Abstract

The development of sustainable agriculture is one of the steps to

achieve national food security. The created agricultural system is

demanded to be able to continue for the present and the future in

managing resources for the sake of agriculture in meeting human

needs. Over time, agricultural land in Indonesia has also decreased

due to the consequences of increasing population growth. It is

predicted that the depreciation of agricultural land can hamper

sustainable agricultural development. Indonesia is included in the wet

tropics, where many soils have undergone a further weathering

process. This soil has low nutrient content, cation exchange capacity,

pH, and organic matter, while for anion exchange capacity, the

exchangeable aluminum, oxide, and clay content are high. High levels

of aluminum in the soil can be toxic to plants. Toxic properties in the

soil, which are caused by aluminum, which can be exchanged on acid

soils, can be overcome by using pyrolysis charcoal, from now on

better known as biochar. The purpose of this research is to design a

biochar making machine to increase food security. Based on the

needs, technology, and several other aspects, this research gets to

design a prototype of a biochar making machine.

1,2,3 Universitas Pembangunan Nasional Veteran Yogyakarta

Abstract

The purpose of this study is to carry out environmental management

in the split-making industry, especially on the spread of dust. In the

field of building construction, at the stage of casting activities, various

construction materials are needed, such as cement, sand, water, iron,

and splits. The existence of a split will further increase the strength of

the cast. Therefore, splits are indispensable in the field of

construction. The raw material for the split is andesite stone. In the

split production process using a stone crusher called a stone crusher.

In the operation of this stone crusher, dust appears generated from

andesite stone flakes which are being reduced in size to split. The dust

will spread to the surrounding environment because it is carried away

by the wind. This condition will cause a negative impact, namely a

decrease in air quality. Therefore, steps / actions should be taken to

minimize the spread of dust, namely by capturing the dust that comes

out of the stone crusher tool carried by the exhaust gas flow. The

equipment used in this research is laboratory scale using fogging

method dust catcher. The sprayer hole diameter is the independent

variable, while the other quantities are the dependent variable.

Research was conducted on the nozzle diameter as much as 5

quantities and carried out 3 replications for each quantity, then

averaged the results. After the research was carried out, the data

obtained from the research showed that the optimum condition for the

mass of dust that was caught by the fog was the diameter of the sprayer

hole 1, 45 mm with an average dust mass that can be caught by the

fog is 14,068.33 µg and an average efficiency value of 72.67%. The

line equation which states the relationship between the variable

sprayer hole diameter and the mass of dust caught by the fog is Y = -

4

14.722.X3 - 782.86 X2 + 4978.5X +6265.7 with a percent error of

1.53%, while the line equation states the relationship between

diameter nozzle with an efficiency value that is Y = 0.1042X3 -

5.3775X2 + 28.608X + 30.564 with an average percent error of

2.37%.

Maju

Heriyanto1, Yuli Fauziah2, Dyah Ayu Irawati3


Abstract

Kelompok Wanita Tani (KWT) SUKAMAJU is a women's

association in Palihan village, Bambanglipuro sub-district. The KWT

activities include monthly social gatherings, savings, and loans,

gardening by growing vegetables and family medicinal plants in the

KWT Sukamaju garden, regular monthly meetings for agricultural

extension agents, and food production. The community service team

provides assistance in the form of increasing production by supporting

production equipment which is considered to be still long for large

quantities of products and multimedia and internet-based marketing

as a means of establishing marketing communications for the group

of craftsmen for processing banana tree food made by KWT Sukamaju.

In the midst of the physical distancing period of the Covid-19

pandemic, community visits to the field as the only marketing

communication channel must stop. The use of internet marketing

means to spur production to be fast and in large numbers. The

difficulty of producing such large quantities is constrained by the tools

and the processing time that must be fast due to a large number of

orders from the internet. The test using linier regression before and

after adding equipment for the production of KWT UMKM has an

average result of 56.54% of the estimate after being given additional

equipment of 55.63%. The result is between estimation and reality

after using the tool, and before using the tool close to an accurate

estimate of between 56, 5% with 55.6% have only a 0.9% difference

in error. Based on the results of the prediction of KWT production

rates using simple linear regression, it can be concluded that the

addition of the data tools used to produce has a big effect, and

6

predictions are close to accuracy using time series data, which greatly

affect the accuracy of prediction calculations.

New Method in The AHP

-Weighting of Criteria For Supplier

Selection

Agus Ristono1, Tri Wahyuningsih2, Agus Munandar3


Abstract

In the coming years, researchers in the supplier selection are more

likely to use a combination of methods of multi-criteria decision

making (MCDM). One method of MCDM which often used in such

combinations is Analytic Hierarchy Process (AHP). The function of

AHP in the combination of MCDM is as weighting in each criteria. In

the AHP weighting, it has a very important problem. The problem is

difficult to obtain consistent results when the amount of matrix is

relatively large. This study proposes a new methodology to solve the

problem. The results of this study indicate that the proposed method

is able to fix the inconsistent matrix data of pair wise comparison to

be consistent.

Keywords : Analytic Hierarchy Process, criteria, consistency index, multi-

criteria decision making.

Trade-Off Value Precision Analysis On

Ideal Solution Value in Distance Based

Multi Criteria Decision Making Techniques

Sutrisno1, Dyah Rachmawati L2

1,2 Universitas Pembangunan Nasional Veteran Yogyakarta

Abstract

Most of the problems that exist in this world fall into the category of

multi-criteria decision-making problems. Multi-criteria decision-

making problems are characterized by conflicting objectives on a

problem to be decided or resolved. Most of the problems in an industry

are also included in the category of multi-criteria decision-making

problems. Multi-criteria decision making is done by determining the

trade-off value of conflicting objective functions using multi-criteria

decision-making techniques. The trade-off value is the compromised

solution value of conflicting objective-function objectives. A good

trade-off value is a trade-off value that is close to the ideal solution

value of each objective function. To determine the trade-off value in

multi-criteria decision making, multi-criteria decision making

techniques can be used. Distance-based multi-criteria decision

making techniques include the minimum deviation method and the

global criterion method. The precision of the trade-off value to the

value of the ideal solution is needed by an industry when making

decisions. A precise trade-off value, one that is very close to its ideal

value, will help an industry get the best decisions. This research will

analyze the multi-criteria decision making techniques based on

distance in producing the trade-off value. Through this research, we

will find the most precise distance-based multi-criteria decision-

making technique in generating trade-off values, so that it can be a

reference for the management of an industry in choosing the best

multi-criteria decision-making technique when solving multi-criteria

decision-making problems in the industry. the. Based on the analysis

that has been done, it can be concluded that the minimum deviation

11

method is more precise than the global criterion method in producing

a trade-off value.

Keywords : distance based multi criteria decision making techniques,

precision, trade off value, ideal value

Abstract

Government education has issued various policies to make

education costs cheaper and more affordable for all people, one of

which is the UKT (Single Tuition Fee) system, a portion of the Single

Tuition Fee that is borne by each student based on their financial

ability. The mechanism for determining the Single Tuition Fee group

is currently still done manually by UPN "Veteran" Yogyakarta. Single

Tuition Fee can be challenged according to the ability of the student's

family. A common objection mechanism is filling in some fundamental

data such as parents' income, electricity bills, water, motorbike, car

taxes and family economic conditions and interviews. Therefore we

need an interactive and responsive Single Tuition Fee rebuttal

mechanism for students in particular and UPN â€œVeteranâ€•

Yogyakarta in general. The Single Tuition Fee system was built on a

web basis. This user-friendly designed system will make it easier for

students to object to Single Tuition Fee during the Covid pandemic or

after the Covid pandemic. The methodology used for this research is

the waterfall. The result of this research is a Single Tuition Fee

objection system capable of filtering and recapitulating.

Keywords : Single Tuition Fee, Refute, Economic, Covid

Abstract

Urban farmer groups have limited yards. Vegetable cultivation can

be conducted using a verticulture system because they can utilize

limited land in urban areas. 10% of yards in urban areas have been

planted, but 90% of the land is still not planted. The existence of

farmer groups can provide an example in managing home yards, and

the products produced can increase income. Meanwhile, the skills and

knowledge of farmer group members regarding verticulture and

organic fertilizer production are still low. One of the ways to improve

skills and knowledge is through training. This study aims to improve

the skills and knowledge of farmers in the cultivation of vegetable

verticulture and the manufacture of liquid organic fertilizers. The

method used is the descriptive method, which is to perform descriptive

analysis to describe the concept of increasing skills and knowledge of

farmers. The results of the training are organic vegetable products

and liquid organic fertilizers. This research will provide a conceptual

framework for farmer groups in applying verticulture technology and

making liquid organic fertilizers on limited land.

Adventri Wibowo3


Abstract

The spread of COVID-19 disease is increasingly widespread in

various regions around the world. The speed of the spread of COVID-

19 varies in different areas. This difference can be caused by multiple

things, such as community habits, government policies, and climate.

Research on predicting the spread of COVID-19 has been carried out

using various methods. One method that can be used to model the

spread of COVID-19 is Agent-Based Modeling. Through this model,

the spread of the virus can be seen from each individual or agent so

that the model will look more real. In making models using Agent-

Based Modeling, standardization is necessary so that the model

description is more complete and easier to understand.

Standardization can be done by determining the ODD (Overview,

Design Concept, and Details) Protocol. This study will discuss the

determination of the ODD Protocol in making agent-based models of

the spread of COVID-19 disease. The ODD protocol that has been

created can be used to build models and coding in the next step in

agent-based modelling.

Abstract

Practical Work (KP) is one of the compulsory courses for students

in Petroleum Engineering Department, UPN Veteran Yogyakarta.

Previously, the administrative system that was implemented used a

manual system. This system has several weaknesses, including the

ineffectiveness of drafting course letter, an activity reporting system,

and an activity assessment. The ineffectiveness of the Practical Work

(KP) administration system can also be seen from the results of the

satisfaction survey of the existing administrative system. The survey

results stated that 34.6% of respondents stated that the administrative

system implemented was less effective. This study creates an online

administration system using an online form (google forms) to simplify

the system for making course letter, reporting and assessing Practical

Work (KP) activities The steps were carried out, among others,

satisfaction surveys, making online forms, making online SOPs,

manuals and socializing the application of the online administration

system. From this research, it is hoped that the administration system

will be more effective and can be paperless

Abstract

The steel industry is one of the industries that concentrate on energy,

and types of upstream industries are prioritized in Indonesia. National

steel demand will continue to increase up to 32 million tonnes in 2025

to make the steel industry remain competitive. The amount of energy

used in the production process, i.e., the energy of LNG and electricity,

and the high prices of raw materials to make the steel industry should

be able to use all three of these things efficiently. On the other hand,

the activity of the production process is often a breakdown on a rolling

machine that makes the production process on the stage rolling line

stop, except the reheating furnace was still burning. This leads to the

inefficiency of using energy and reduce the productivity of reinforced

concrete that can be generated. One of the causes of the breakdown in

the rolling machine is negligence labor. The study aims to calculate

the level of efficiency in production units, rolling mills one and two.

The disruption of the production process is the breakdown in the

production of rolling mills. The research uses the approach of the

Data Envelopment Analysis model CRS input-oriented. From the

evaluation is known that there are eight concrete iron production units

are inefficient by an average of 98%. Then, a significant improvement

potential values of input parameters using the unit of production of

rolling mills is the use of electrical energy by 93.56%, amounting to

65.20% of LNG energy, labor amounted to 49.00%, and raw materials

by 11.92%. One of the causes of the potential value improvement or

inefficient use of the input parameter is the breakdown of the engine

by adding biosurfactants or increasing the temperature that has been

carried out in the EOR process. Naïve Bayes Classifier is used to

classify oil data into three categories: light oil, medium oil, and heavy

oil, based on the prediction of the viscosity value. The Naïve Bayes

Classifier is a robust algorithm for performing machine learning-

based predictive modeling that applies the Bayes theorem. This

predictive modeling for the physical properties of crude oil was built

using the Python programming language and the PyQt5 library to

build desktop-based applications. The classification of oil has arrived

at labeling the prediction results of crude oil's viscosity into three

categories, namely light oil, medium oil, and heavy oil. The test results

with testing data produce accurate data; the predicted value is within

the specified range.

Abstract

These instant herbs and instant red ginger are much in demand by

consumers because they taste good and are fresh and can also

increase the body's immunity. The business of instant herbal medicine

and instant red ginger has not been managed professionally. This is

indicated by the quality of the product that has not been standardized,

that is sometimes too wet and sometimes too dry, resulting in

durability and taste of the product. Since the Covid -19 pandemic,

demand has increased by almost 400%. Meanwhile, the production of

these two business groups is now only able to meet 50% to 60%. Based

on the partners' problems, to increase production and improve the

quality of herbal medicine, practically designed chopper machines

have been used. The chopper machine that is donated to this partner

is capable of chopping various types and sizes of herbal medicine with

a production speed of around 30 kg of wet herbs per hour or greater

± 50 times the manual work done by the partner at this time.

Production process training and mentoring are also carried out so

that the product quality lasts longer and the taste of herbs does not

change. With technological innovation and business training carried

out by the service team, the partners feel very useful, that is: 1).

Organization is able to increase production capacity to fullfill demand

2). The quality of the herbal products will be better 3) Better

organizational management 4). The economy of the members of the

crafters' group has improved mor.

Abstract

Identifying the area of interest is a must for every student in each

study program before choosing the elective courses. Ideally, a student

chooses their area of interest by considering the scores of all courses

that they have been completed. Nevertheless, they do not thoughtfully

choose their interest since they may follow what their friends' are.

Decide to choose the wrong area of interest may result in difficulty

while completing their education. This research aims to help students'

academic supervisors guide their students by implementing a decision

support system to help students and academic supervisors determine

their area of interest. Decision support systems in this research are

built through two stages: observation, decision-support modelling.

Observations were made to determine the criteria and attributes used.

The decision support model was made using the Fuzzy Multi-Attribute

Decision Making (FMADM) method, followed by ranking the result to

obtain the best possible recommendation using the Simple Additive

Weighting (SAW) method. With FMADM and SAW, the decision

support system has been successfully carried out and resulted in the

recommendations ranking to support the assortment of area of interest

for Information System students in UPN "Veteran" Yogyakarta.

Improving The Quality of Ceramic Products

Through The Application of The Taguchi

Multi Response Method to Increase The

Competitiveness of Ceramic UKM in The

Global Era (Case Study at The Kasongan

Ceramics UKM Center, Bantul, DIY)

Dyah Rachmawti L1, Sutrisno2


Abstract

Kasongan Ceramic UKM Center is an association of UKM

which makes goods made from clay. Kasongan Ceramic UKM

Center, located in Bantul Regency, DIY. The problem that is

often experienced by Kasongan Ceramics Center is that

products that are often cracked, warped, and easily brittle. The

total production of Kasongan UKM Center from September

2019 to February 2020 was 32,256 units, with the number of

defective products amounting to 3,873 or 12% of the total

production. Based on the studies that have been carried out, it

can be concluded that the crack, warping, and brittle defects that

occur are caused by the lack of maximum flexural strength and

the high percentage of dry shrinkage in the ceramic products

produced. To maximize the flexural strength and minimize the

percentage of dry shrinkage in the resulting ceramic products,

the optimal ceramic manufacturing process parameters will be

determined using the Taguchi multi response method. To

maximize the flexural strength and minimize the percentage of

dry shrinkage in the process of making ceramics using the

Taguchi multi response method, it is necessary to carry out an

experimental design. The first thing to do is to determine the

30

controlled factors and levels in the ceramic manufacturing

process that affect the flexural strength and dry shrinkage of

ceramics. After that determine a suitable orthogonal array and

perform experiments based on the specified orthogonal array.

The experimental results will be tested for flexural strength and

dry shrinkage percentage in the laboratory. The resulting

flexural strength and dry shrinkage percentage data will be

processed to determine the optimal ceramic manufacturing

process parameters that maximize the flexural strength and

minimize the percentage of ceramic dry shrinkage. Based on the

data processing carried out, it is found that the optimal ceramic-

making process parameters at the Kasongan Ceramics UKM

Center that maximize the flexural strength and minimize the

percentage of dry ceramic shrinkage are 2 parts Godean soil

composition, 1 part kasongan soil composition, 1 part sand

composition, and combustion using a tub open.

Abstract

Nutrient availability will affect plant growth, especially at the early

development of plant. Organic and inorganic fertilizer provide

different level of nutrient. This research aimed to study the early

growth of tomato cultivated under different fertilizer types and

dosages. The green house experiment was set in a Randomized

Completely Block Design. The treatments were various type of

fertilizer (Liquid Organic Fertilizer/LOF, inorganic fertilizer,

LOF+AB Mix) and different dosages per day (225 mL, 450 mL, 675

mL 900 mL). Tomatoes were planted in polybags in a green house and

with treatments according to the experimental design, each treatment

were repeated three times. Fertilizer was applied together with

irrigation water, as drip fertigation and otomatically set as to irrigate

at 06.00 am. 12.00 pm, 06.00 pm. Liquid fertilizer concentration

applied was 5 mL/L. Plant height and number of leaves were observed

every two days for two weeks. The results showed there was no

interaction between fertilizer type and fertilizer dosage in affecting

plant height and number of leaves during early vegetative gowth of

tomato plant, except for plant height at 8 dap (days after planting) and

10 dap. Until 6 dap, application of inorganic fertilizer and 225 mL

liquid fertilizer/day resulted in significantly higher plant height than

other treatments. However, at 8 dap until 16 dap, application of LOF+

NPK Mix and 450 mL liquid fertilizer/day resulted in significantly

higher plant height and higher number of plant leaves than other

33

treatments. This result indicating that mixed between inorganic and

organic fertilizer support better growth of tomato plant at their early

stage. Futher study, examining the effect of types of fertilizer and

fertilizer dosage supplied in drip irrigation on the yield and quality of

tomato is needed to confirm the recent results.

Abstract

The development of information technology has now been widely

used to facilitate, accelerate and streamline work. The presence

system that is still being applied is a type of precession using on-site

presence. When viewed from a special point of view, lecturers have a

weakness because they have to come to the location of the biometric

machine. The new technology of attendance system using location

(LBS) is an alternative solution for some employees, especially

lecturers who often have scheduled in the field. Even though it is not

on campus, this location-based presence is able to capture the position

of employees during attendance. The truth data is matched with a

warrant from the leadership for the correctness of the employee's

path. The result of this research is that location-based employee

attendance applications have been developed. With the location-based

attendance system that is integrated with the official letter system

(SIRADI), employees who have difficulty coming to campus locations

to do fingers can still get their rights in a position when the online

presence is doing other tri dharma activities.

Abstract

Sentiment and emotion analysis on social media is an interesting

study because it reveals the emotional state of the public in a domain.

The challenges in sentiment analysis research in Indonesian are

inefficient preprocessing, inaccurate feature extraction methods and

low classification accuracy by machine learning. One aspect of

sentiment analysis is fanaticism. Fanaticism contains an emotional

element in sentiment analysis. This article discusses how to detect

opinions that contain political fanaticism, then categorize them into

several polarities of political fanaticism. Feature extraction is done

by processing sentiment, anger, happines, disgust, surprise, fear, and

hate speech analysis. Knowledge for classification are K-NN, Naive

Bayes, Random Forest and Decision Tree. The aim is to find out the

best combination of machine learning methods for feature extraction

and finally used for fanaticism categorization. The best method is

Random Forest with accuracy of 81% and will be used as a final

method for monitoring fanaticism on social media.

Abstract

Polymer injection is a method to get higher oil recovery by

increasing the viscosity of displacing fluid (water / brine and polymer

solution) which makes the mobility of displaced fluid (oil) become

higher than the mobility of polymer solution. It will result in better oil

sweep efficiency due to front stability and reduction of viscous

fingering effect. Therefore, polymers are used to overcome the

problem of viscous fingering that occurs in water flooding. However,

implementing polymer injection on field scale needs previous

experimental study to analyze the performance and flow behavior of

polymer injection in obtaining polymer with certain conditions that

can give optimum oil recovery. At this stage of experimental study, a

micromodel is used in order to visualize the flow behavior of polymer

injection clearly and in detail. If within experimental study we already

got the optimum polymer with its conditions, then a pilot test can be

conducted. In this case, pilot test is an experimental test of a project

that carried out on a certain well or reservoir to find out whether the

project is profitable (economically) or not, where if the project is

successful, polymer injection can be implemented on a field scale. This

review paper will deeply discuss about the factors that can affect the

performance of polymer injection in oil recovery at pore scale by

using micromodel.

Abstract

acquisitions require enough space to obtain detailed information.

However, in certain conditions, such as limited measurement

instruments and conditions in the research area, this cannot be done.

Several ways can be applied such as improvisation during data

acquisition or when processing data. In this study, a spatial frequency

data processing approach has been carried out which aims to

enhancement and obtain target anomalies more clearly using spatial

filter analysis. The target of this research is the mineralization zone in

Mount Parang Karangsambung, Kebumen Regency, Central Java,

using the Time Domain Induced Polarization method with 4 lines

using a Dipole-dipole configuration with a measuring spacing of 10

meters. The output of this research is to compare the real data

processing of 10 meters spatial field with spatial filter processing to

be 5 meters. The processing results show an increase in the sharpness

of the resistivity and chargeability images on the 5-meter spatial data.

There was an increase in the target image, namely mineralization as

indicated by the response of contrast resistivity and chargeability. The

use of spatial filters can increase the resolution of the resistivity and

chargeability sections so that the lithology and mineralization zone

can be well defined

Abstract

The research area is administratively located in the Tumpang Pitu

Pit Site, Sumberagung Village, Pesanggaran District, Banyuwangi

Regency, East Java Province which is included in the coordinate

system of the Universal Transfer Mercator (UTM) WGS 84 zone 50S.

Compared with phreatomagmatic activity, which is caused by

interaction / direct contact between the body of magma and water,

phreatic activity releases less energy, and consequently smaller

phreatic breccia dimensions. Phreatic breccia or hydrothermal

breccias are quite often misinterpreted as phreatomagmatic

structures. Hydrothermal breccias are formed in the hydrothermal

system, generally at a depth of 200-300 m, and rarely at a depth of

500-1000 m. Based on geological structure analysis, it can be seen on

the structure pattern map in the Tumpang Pitu area, there are 2 major

faults in the Northwest - Southeast direction. These 2 major faults are

the main controller for the formation of minor faults in the Tumpang

Pitu area. There is a structural pattern that develops between these 2

major faults, which is a "metallogentically fertile structure" fault or in

this pattern mineralization occurs. Based on field observations, core

drilling, ASD analysis, and petrographic analysis, the type of

alteration based on the mineral assemblage is divided into five, they

are quartz, quartz-alunite, quartz kaolinite, kaolinite-

montmorillonite-chlorite, and kaolinite-montmorillonite alteration.

Mineralization rocks in the study area are volcanic and volcanic

53

clastic rocks and occur as vuggy replacements and stockworks,

disseminated, fractures, and veins. Hydrothermal breccias in the

Tumpang Pitu area are characterized by enrichment zones of the

hydrothermal system with an abundance of sulfides (Goetite, Hematite

and Limonite), with Jigsaw and Crackle breccia textures, the mass in

the form of sulfide minerals Goetite, Limonite, Hematite, 50-90%

silica content and weak to strong vuggy texture. Veins and veinlet that

develop are Sugary quartz - sulphide veins (chalcopyrite, bornite) (A

Type), sulphide-center line crystalline veins (B Type), pyrite + quartz-

chalcopyrite veins (D Type), early biotite (EB Type), High sulfidation

epithermal veins (pyrite-bornite-chalcocite-covellite-tetrahedrite-

tennatite-enargite) (HSE type), and Magnetite veins (M Type).

Assuming homogenisation temperature is identical to formation

Hafiz Hamdalah1, Eko Wibowo2


Abstract

Kalirejo, Kokap, Kulonprogo area is part of Yogyakarta in the west

which borders the Province of Central Java. In general, the

geomorphology of this research area consists of hills with varying

slopes ranging from 15o - 60o, lithology consists of massive andesite

intrusion with intense weathering, this can be a mass movement. The

study uses geoelectric and geomagnetic approaches to identify

components that allow mass movement or landslides to occur. Based

on the response of geoelectric data, it is known that andesite rocks

which have impermeable properties can become a slide plane having

a resistivity contrast between 100 - 3000 ohm meters. Geoelectric data

also describes the presence of surface aquifers which can be an

important component in landslides. The water-saturated lithology has

a resistivity range of 10 - 40 ohm meters. Based on the analysis of

geomagnetic data with a magnetic intensity value range ranging from

-400 - 1400 nT, it is known that the research area has a fairly high

structural intensity. Analysis of geoelectric data shows that the

thickness of the unconsolidated sediment is thick enough and the layer

underneath is an impermeable rock layer, so it can be concluded that

has a high potential for landslides

Abstract

Mining activities have a considerable influence on groundwater

availability. One of the efforts to manage the quantity and quality of

groundwater is by analyzing the vulnerability of groundwater.

Various methods have been applied to analyze groundwater

vulnerability, one of which is the SINTACS method. This method

consists of seven parameters, namely groundwater level depth, aquifer

type, infiltration rate, unsaturated zone material, soil type, hydraulic

conductivity, and topography. These parameters are classified based

on the rating and weight of the level of groundwater vulnerability. The

results of the classification will be processed using ArcGIS software

to determine areas that are potentially vulnerable to groundwater

vulnerability. The results of the level of groundwater vulnerability in

the study area showed 9% low vulnerability, 63% moderate

vulnerability, 23% high vulnerability, 5% high vulnerability.

Abstract

Groundwater is one of the sources of community water needs.

Technically, groundwater potential in each area depends on the

condition\ of the abiotic components which are the providers,

distributors and storage of groundwater. Groundwater providing,

distributing and storing media are strongly controlled by geological

conditions which description the potential presence of groundwater.

The geological conditions of each area are different from one another,

so it is important to conduct research on groundwater potential based

on geological conditions as one of the basic steps to fulfillment

community water needs. Candi Abang area is a hilly area with

constituent rocks in the form of pyroclastic products which make it

difficult for groundwater to be stored in it. This condition is interesting

to know the groundwater potential as the basis for fulfillment

community water needs. Research on groundwater potential in the

Candi Abang Area was carried out by mapping and direct

measurement of geological components including; landform, soil

thickness, lithology, groundwater level depth, rock weathering level,

and density of discontinuity fields. Then, analyzed with a weighting

method based on the level of influence. The results of the weighting

analysis obtained the level of groundwater potential in the Candi

Abang area are very difficult, difficult, easy, and very easy.

Abstract

The research location is in the village of Wukirsari, Imogiri Imogiri,

Bantul Regency, Special Region of Yogyakarta. The study was

conducted quantitatively and qualitatively, with data collection by

purposive and snowball. Landslide area of 7,922 m2 on 17/3/2019 was

at coordinates 433409.04 mE, 9124439.00 mS, moving towards

N190oE. The type of landslide is found in the form of rock flow and

debris slide. Landslides are triggered by high rainfall and nonworking

drainage system in the study area so that the water load increases

beyond the critical limit. Until now there has been no landslide

information system. Collecting the geology information, using

participatory mapping, has been able to increase community based

awareness of resilience in (1) assessing landslide risk, (2) monitoring

character of landslide haz-ards, (3) disseminating information on

potential landslides, and (4) strengthening community response ca-

Abstract

Sclerotinite as maceral from Group Inertinite is a mycelia

mushroom, containing black melanin in the form of black cells. The

fungus is rich in melanin to form sclerotinite cells. Sclerotinite is oval

or circular consisting of single cells (single sclerotinite) and multiple

cells (multiple sclerotinite), has high reflectivity (Stach et al., 1982).

The purpose of this study was to determine the condition of the peat

swamp facies or changes in the swamp water level in Seam-B coal in

Marapi area, Lahat, South Sumatra. Changes in the water level of peat

swamps in tropical climates affect the growth system of sclerotinite

fungi on the peat surface. This condition can be seen from the

Gelification Index (GI) values between 0.01 - 0.15 and various Tissue

Preservation Index (TPI) between 8.68 - 36.50 (Diessel, 1986). The

Seam-B coal facies in the Marapi area of South Sumatra consist of:

limnic, limno-telmatic and marsh, these terms are used to determine

the depositional environment based on the classification of the

hydrological regime according to water level depth (Mitsch and

Gosselink, 1986). Based on the results of the coal facies study

(Diessel, 1986), there are variations of Seam-B coal facies which are

deposited in limnic (wet / very humid) conditions where the

sclerotinite fungus develops colony to form multiple sclerotinite in

sample B (2), while sample B ( 1), B (3) and B (4) are deposited in

conditions of marsh facies (moist soil) to limno-telmatic (relatively

63

dry) so that some of the sclerotinite fungi develop separately to form

a single sclerotinite (in relatively dry conditions) and some live

independently colonize

The Effects of VICOIL BOPANPROG

Usage as a Substitute of Crude Oil for Oil-

Based Drilling Fluids

Pasaribu3


Abstract

The use of water base mud often faces some difficulties in dealing

with shale zones which can cause shale problems. Oil based mud has

better performance than water based mud in overcoming shale

problems. However oil base mud can cause unfavorable

environmental impacts and it iss more costly than water base mud.

Various efforts were made to find oil base mud materials that are

environmentally friendly and do not cost too much money, but still

function as a standard oil base mud with all its advantages compared

to water base mud. Oil base mud by using VICOIL Bopanprog as its

liquid phase is expected to be a substitute material for oil based mud.

The first test is to analyze the shale content of the cutting samples

which will be tested on the designed mud by using MBT and XRD.

From the results of these tests, we can find out the potential shale

problems that will occur. Then we can determine the correct mud

composition to prevent the shale problem from happening. To

determine the physical and rheological properties of the designed

mud, tests are carried out in the laboratory. After meeting the testing

standards, the mud filtrate is tested to the cutting sample that has been

analyzed at the beginning to determine its performance in overcoming

shale problems. From the research results, the use of VICOIL

Bopanprog oil based mud has met the normal oil base mud standard

and it is able to overcome clay swelling caused by smectite and illite

minerals from the tested cutting samples. However, in testing the

cutting samples also contain kaolinite minerals which tend to cause

sloughing problems. OBM VICOIL also has good mechanical,

67

hydraulics, and or properties of drilling mud to prevent shale

sloughing.

A Review of Coal Liquefaction Using Direct

Coal Liquefaction (DCL) and Indirect Coal

Liquefaction (ICL) Techniques

Mitha Puspitasari1, Mahreni2


Abstract

Coal liquefaction is a process of converting solid coal fuel into

liquid fuel. This process is developed by various countries to overcome

the scarcity of liquid fuels, therefore, this coal liquefaction is very

useful for countries that have few petroleum reserves, yet, have large

coal reserves. There are two coal liquefaction techniques, namely

direct coal liquefaction (DCL) and indirect coal liquefaction (ICL). In

ICL, there is a gasification process that usually develops products,

generating Fischer-Tropsch (F-T) liquid, methanol (CH3OH/MeOH),

and dimethyl ether (CH3OCH3/DME). On the other hand, DCL

involves a hydrogenation reaction to produce synthetic gasoline and

diesel which is the same as LPG, a hydrocarbon fuel product similar

to hydrocarbon fuel derived from petroleum. This paper discusses the

ICL and DCL coal liquefaction techniques, including the process

stages, the type of catalyst used, and the products resulted from these

techniques.

Characteristics of Coal and Coal Ash

Edy Nursanto1, Adi Ilcham2


Abstract

The physical character or composition of coal in the form of deposits

used as trading materials are different. This is due to conditions,

including peat formation, change in geological time, and methods or

process of mining. The characteristics of coal, including water

(moisture), volatile matter, porosity, density, grindability, friability,

weathering, size composition, strength, and abrasiveness determine

the use. Furthermore, ash is a residue obtained from mineral matter

due to changes in coal. The chemical composition is different with less

weight than the mineral matter present in the original form. Also, the

change in mass recorded during this entire process is attributed to

water loss from the original silicate, CO2 and oxide from carbonate

and pyrite oxide, respectively. However, the main components of ash

elements include Sodium, Calcium, Magnesium, Potassium,

Aluminum, Silicon, Iron, and Sulfur

Abstract

Steam flooding (SF) and Cyclic Steam Stimulation (CSS) are

thermal recovery methods that had been proven to improve oil

recovery from heavy oil reservoir. Our previous work shows that the

combination of CSS and SF give the better result than solely CSS or

SF. However, the optimum operating parameter of this combination is

yet to be determined. Our current work aims to determine the optimum

development scenario of a combined CSS-SF applied to X-Field, a

heavy oil field located in Sumatera, Indonesia. A polynomial proxy

model is developed to evaluate the objective function, by running

several simulations for the field subsurface model using CMG-STARS

simulator and CMOS to assist multiple simulations. Optimum

development scenario is obtained through maximization of objective

function. This work shows that the combination of proxy model

development and optimization results in best scenario of combined

CSS-SF for heavy oil recovery in X-Field.

Abstract

Naturally fractured carbonate reservoirs generally have very large

residual reserves and are suitable for advanced production stages,

where oil recovery in the natural fracture reservoir of carbonate can

be carried out by injecting polymers. This study uses a hypothetical

model using 4 wells, where during the initialization process it has an

OOIP of 12.129 MMSTB. Running was performed at basecase, then

basecase showed an RF of 8% with a cumulative production of 973.66

MSTB. This small recovery factor is the reason why polymer is used,

the working mechanism of the polymer is by reducing the mobility

ratio so that the viscosity of the water will increase and be able to

sweep away the oil that is still left in the reservoir rock. There are 5

scenarios used in this study, where each scenario has different

concentrations of 50 lb/d, 100 lb/d, 150 lb/d, 150 lb/d, 200 lb/d, 250

lb/d, respectively. , then each scenario is tested with different rates in

succession of 500 bbl / day, 750 bbl / day, 1000 bbl/day, 1250 bbl/day,

1500 bbl/day, but the pattern of each scenario is the same as using

inverted-5-spot pattern. From the five scenarios, the best scenario is

obtained in the third scenario, namely using a polymer concentration

of 150 lb/d and a rate of 1250 bbl/d can increase RF by 10.81 to

18.81% with a cumulative production of 2.28178125 MMSTB. Keywords : Naturally Fractured Reservoir, Reservoir Simulation,

Modelling of A Low Salinity Waterflooding

in Carbonate Reservoir

Suranto1, Ratna Widyaningsih2, Hidayat Tulloh3


Abstract

Some studies about low salinity waterflooding (LSW) was carried

out to observe the mechanisms of LSW and the response of each

reservoir in a certain condition. The majority topics about LSW are in

a laboratory investigation and in a sandstone implementation.

Although the benefits of LSW were reported, but only a few studies

discussed about the LSW simulation process especially in carbonates

reservoir. Therefore, this research is deemed necessary to discuss

about the modelling process of LSW in carbonates reservoir for a

comprehensive understanding in simulation application. One of

primary mechanism of LSW in carbonate is wettability alteration. The

geochemistry software which is used provides the calculation of some

reactions that affect to the oil recovery mechanism. By developing a

homogeneous cubic model with 5-spot pattern, the simulation

scenarios are arranged to compare the injection water using

formation water (salinity is about 179,730 ppm) to lower salinity brine

by diluting 10 and 20 times of formation water. The LSW process

during 50 years improves oil recovery about 4% more higher than

formation water injection. But it has potential increasing oil recovery

if we see the trend. It can be concluded that a low salinity

waterflooding is an opportune method that considered to be applied

for increasing oil recovery in carbonates reservoir. Eventhough the

process is not immediately visible because it needs time for reaction,

it means the sooner LSW implemented is suggested. Keywords : low salinity waterflooding, enhanced oil recovery, recovery

Abstract

The core sampling procedure must be carried out properly in order

to produce cores of good quality. A good core sample will have an

effect on the accuracy on the data that will be used. The core sampling

method consists of Drill-string Coring and Wireline Coring. EOR

study is a laboratory study to measure compatibility and amount of

recovery. In that laboratory study, core samples from the reservoir are

required to be carried out by the EOR study. Because the cost of taking

the original core samples from the reservoir is quite expensive, usually

the core samples used in this study often called artificial core. A good

candidate for artificial core is a core that has similar characteristics

and properties to the condition of the reservoir. The candidate quality

of core samples is very important because the sample will represent

the properties of the reservoir. By evaluating physical properties of

the rock such as porosity, permeability, rock mineralogy, and the

distribution of physical properties in the core sample, the best quality

of the core sample will be obtained where the sample can represent

the reservoir in the research area that EOR study will be conducted.

Abstract

Increasing the people's energy needs requires alternatives, one of

which is using agricultural waste materials. Carcoal briquette is a

solid fuel made from carcoal with a pressing process so that it

coagulates with a certain density, can be burned continuously and has

a high calori value. Conversion of various kinds of agricultural waste

to carcoal briquettes needs to be done in order to meet the SNI

requirements. In this research, briquettes will be made from raw

materials of peanut shells, rubber seed shells and sonokeling wood

because they have high cellulose content. The aim of this research is

to produce charcoal briquettes and test their characteristics. The

study was designed with 2 variables, namely the type of raw material

(peanut shells, rubber seed shells and sonokeling wood) and pyrolysis

temperature: 300, 400, 500 and 600oC. The size of the charcoal

powder is -35 +50 mesh, 8% starch adhesive, and 100 kg / cm2 of

pressing pressure. The parameters measured were moisture content

(%), ash content (%), volatile matter content (%), and fixed carbon

content dan calorific value (cal/g). The results showed that, the best

characteristic of carcoal briquettes were obtained from rubber seed

shells, temperature of pyrolysis of 600oC, with the moisture content of

7.4%, ash content of 3.55%, volatile matter content of 13.44%, fixed

carbon content of 75.92% and calorific value of 7105 cal/g.

Abstract

The increasing consumption of diesel oil results in depletion of

petroleum supply so that biodiesel is made out of crude palm oil. The

purpose of this study was to determine the effect of production of

biodiesel by using NaOH catalysts. First, crude palm oil is analyzed

for its free fatty acid content. If the free fatty acid is less than 5%, the

transesterification process can be carried out immediately, if its more

than 5%, the esterification process is carried out first. The

esterification process lasts for 60 minutes temperature of 60°C with

an acid catalyst H2SO4 then separated and washed. After the washing

process, the transesterification process is continued with NaOH

catalyst for 30 minutes at 60°C and then the washing process is

proceeded in order to purify the results. From the research that has

been done, the result of biodiesel has a yield 87.2866%, kinematic

viscosity 4.655 mm2/s, flash point 110oC, pour point 12oC, and density

at 15oC of 0.875 g/ml.

method. Like solvotermal/hidrotermal, mechanochemical,

microwave-assisted, sonochemical, electrochemical and layer by

layer synthesis. Moreover, it is to knowing implementation MOFs as

a heterogeneous catalyst in chemical industry. Based on review paper

conducted we know that MOFs synthesis with used sonochemical

method is good better than other method. It is because sonochemical

method need short crystallization time and eco-friendly and using

energy like ultrasonic radiation (20kHz-10MHz). MOFs are can used

to fulfil like heterogeneous catalyst because MOFs has widely surface,

similar pore size and has high thermal stability. MOFs application as

Abstract

Plastics, rubber tires and styrofoams are commonly used as

disposable materials in our society, which contribute to the constant

buildup of waste accumulation. A method called waste pyrolysis is

able to transform the aforementioned waste into fuels. This method

was performed at temperature of 350 - 500°C with variations of

styrofoam decoy mass are 50 gram, 100 gram, 150 gram, 200 gram,

and 250 gram and for tire decoy mass are 500 gram, 750 gram, 1000

gram, 1250 gram, and 1500 gram. A decoy mass variation that

produce the highest yield production is subjected to catalyst addition.

Active zeolite catalyst with 2%, 4%, 6%, 8%, and 10% content level

was added to each material in order to obtain the volume of pyrolysis

result. In this research, we got the optimum decoy mass of 200 gram

with 84% yield for styrofoam and 750 gram with 32,67% yield for tire.

The optimum catalyst percentage for pyrolysis oil volume derived

from styrofoam is 6% with 90% yield and the optimum percentage for

the volume of tire-derived pyrolysis oil is 10% with 45,33% of yield.

Based on the density and viscosity of conventional fuels, biodiesel has

the most similar characteristic to our result. And based on flash point,

fire point, and calorific value of conventional fuels, the one with the

closest characteristic is kerosene. The utilization of styrofoams and

Empowerment of Women Farmer Groups in

Salamrejo Village Kulon Progo Regency

Through Independent Procurement of

Organic Fertilizer

Nanik Dara Senjawati1, Liana Fatma Leslie Pratiwi2


Abstract

Inorganic fertilizer has some weaknesses in its application which is

not good for plant growth, not environmentally friendly and has a

fairly expensive price. The use of inorganic fertilizers especially on

the household scale can be replaced with organic fertilizers that can

be made independently. In addition to being good for plant growth,

the costs incurred to make it are quite cheap. The purpose of this

activity is so that the group of farmers in each hamlet can utilize the

resources that exist around it that can increase the productivity of

agricultural crops and reduce the costs incurred for crop production

activities by producing organic fertilizers independently and limiting

the use of chemical fertilizers. The method carried out in this activity

is counseling (education-agriculture) about the manufacture of MOL

(Micro Organisms Local) and the utilization of organic waste around

the residence to be made into liquid organic fertilizer. The results of

the activities obtained in the form of increasing knowledge of the

members of women farmer group about the function of making MOL

(Micro Organisms Local) and how to make liquid organic fertilizer by

utilizing organic waste that is around the place of residence so as to

reduce the use of inorganic fertilizers and save the cost of farming.

This community service activity is proven to solve the problems of the

members of the women farmer group and utilize the resources that

exist around it that can increase the productivity of agricultural crops

and reduce the costs incurred for crop production activities.

Eko Amiadji Julianto1, Partoyo2, Sri Suharsih3


Abstract

One of the volcanoes known as the most active mountain in the world

is Mount Merapi. The impact of the Merapi eruption can lead to the

addition of volcanic material whose deposits can fertilize the soil. This

study aims to determine the relationship of several fertility parameters

to the production of Ciherang variety on regosol soil in the Southern

Slopes of Merapi, Yogyakarta, Indonesia. Observations were made by

taking soil fertility samples as many as 37 demonstration plots using

the stratified purposive sampling method. Statistical data from the

relationship between fertility parameters on rice production were

processed using simple linear regression. From this simple linear

regression, we can find parameters that have a significant effect and

non-significant effects on rice production and also information on

fertility parameters in the form available in the soil with a greater

effect than those in the total form. The results showed that phosphorus

in the total form has a value of R2 = 0.3229 to DGH, whereas

phosphorus in the available form (Bray 1) has a value of R2 = 0.7142

to plant production (DGH). Potassium in the total form has a value of

R2 = 0.1124 to GKP, while potassium in the form available (Morgan

K2O) has a value of R2 = 0.3233 to DGH. Cation Exchange Capacity

(CEC) and Base Saturation (BS) each have a value of 0.3651 and

0.5758 for plant production (DGH). C-org and Si each have R2 =

0.4639 and 0.324 values for crop production (DGH). R2 values close

to 0.5 in the cross section data can be said to be high.

Abstract

Citrus production in Indonesia and a part of the world facing CVPD

or greening disease as the most devastating disease. Diaphorina citri

play an important role as pathogen main vector. Guava leave raise as

a potential control means for reducing D. citri population. Research

was conducted to investigate the response of D. citri to various guava

shoots. Responses to grinded dried upper shoot of 50oC and 80oC of

white, non-seed, and red guava shoots to ten mixed gender of adult

psyllids were determined in Y-tube olfactometer. The result shows that

D. citri adult refused to move into guava shoots odours sources. The

number of D. citri moved to citrus leave extract with the addition of

upper shoots leave extract of red guava and non-seed guava is

2.53±0.22 and 3.80±0.31 respectively. The number of D. citri move is

2.60±0.13 and 5.47±0.22 for red guava and white guava odour

sources respectively. The responses increased as the increase of

drying temperature. Highest response is found from white guava

shoots, followed by non-seed guava and red guava. It is suggested that

properties of red guava shoots have the highest potency for reducing

D. citri population. However, properties of red guava upper shoot still

have attractant effect to M. sexmaculatus, predator of D. citri.

Abstract

Decreased yield and quality of chilies was mainly due to the attack

of fruit flies and white flies as virus-carrying vectors. Until now, to

control these pests farmers still rely on the use of synthetic chemical

pesticides that leave residues. Efforts to control pathogens and

improve yield and quality of red chilies use biological agents

Trichoderma sp., Mycorrhizal and organic materials that have been

completely decomposed. The objective of this research was to examine

the effect of level of decomposition of leaf litter in combination with

application of different biological control agents and NPK dosage on

plant growth. This experiment was conducted at Experiental Garden,

Condongcatur Campus, Depok, Sleman, Yogyakarta from June until

September 2020. The experiment was arranged according to

Randomized Completely Block Design with two factors, each

treatment consist of three replicates.The first factor was

decomposition of leaf litter with C/N ratio of 28.52 and decomposition

of leaf litter with C/N ratio of 16.57. The second factor was NPK

dosage and/or types of biological control agents with the following

five treatments: 1) Only recommended NPK dosage (500 kg.ha-1), 2)

Combining Trichoderma and 50% recommended NPK dosage, 3)

Combining Mycorrhiza and 50% recommended NPK dosage, 4)

Combining PGPR and 50% recommended NPK dosage, 5) Pest

control, 6) Stimulant. The data were subjected to analysis of variance

followed by Duncan’s Multiple Range Test. The result of the

experiment showed that the decomposition of leaf litter with C/N ratio

of 28.52significantly improved the plant height at 14, 28, and 42 days

102

after transplanting and shoot dry weight in comparison with chili that

was treated by decomposition of leaf litter with C/N ratio of 16.57. The

using of decomposition of leaf litter with C/N ratio of 16.57 in

combination with biological control agents + 50% recommended

NPK dosage significantly increased number of branches and had a

faster flowering stage. However there were no significant different

among three types of biological control agents in affecting the number

of branches and flowering stage. The growth plants treated with NPK

fertilizer only has the lowest plant growth compare to other

treatments.It is suggested that to increase plant growth and accelerate

flowering stage, chili can be treated with fully decomposed leaf litter

combine with biocontrol agents and 50% recommended NPK.

Abstract

Data quality and transparency are of the utmost importance for

organizations. Collecting original data from the source without any

indication of interruption or interception is an indicator of an attack

on the server. The most common attack is Denial of Service (DoS)

which is a type of pattern that will crash, shutdown, reboot, or not

respond to services of a host on the network. One technique for this

attack is the use of the k-means clustering method with a snort. This

study aims to design a SNORT-Intrusion Detection System (IDS)

application with a k-means algorithm that can categorize attacks into

high, medium and low attacks and is accurate on DoS attacks. Snort

accuracy testing functions to measure the packet size detected by snort

using an attack application, then the number of packets caught can be

categorized using clustering techniques. From the measurement

results, the increase was 73.18%. The contribution of this research is

a survey and analysis of anomalous packets contained in a network. It

can identify the level of types of attacks and take preventive measures

from these attacks.

Abstract

The COVID-19 pandemic has a profound impact on all groups,

including governments, agencies, and individuals. It can make anxiety

have a bad effect. So it is necessary to detect the existence of anxiety

from the government to suppress and improve the community's

psychology. This research aims to design text mining to detect anxiety

during a pandemic by applying machine learning technology. Two

methods of machine learning are designed, namely, random forest and

XGBOOST. This design uses a sample of data from YouTube

comments with a total of 4862 consisting of 3211 for negative data

and 1651 for positive data. Negative data identify anxiety, while

positive data identifies hope (not worry). The design of the application

of this method was carried out by preliminary testing with three

calculations, namely accuracy, precision, and recall. The accuracy of

the Random Forest and XGBOOST methods is 83% and 73%.

Meanwhile, precision and recall have an inversely proportional value.

Random Forest has a precision value greater than 45% compared to

XGBOOST. Whereas Recall, XGBOOST is bigger than ten compared

to Random Forest. Random Forest can reference machine learning

methods to detect someone's anxiety based on data from social media.

Non-Invasive Anaemia Screening Using

Nails and Palms Photos

Mangaras Yanu Florestiyanto1, Nandha Juniaroesita Peksi2


Abstract

Anaemia is a condition where the haemoglobin level is below

standard. Haemoglobin is an iron-rich protein that gives blood its

red colour and is tasked with helping red blood cells carry oxygen

from the lungs throughout the body including essential body organs

such as the heart, kidneys, and other organs. So that if anaemia is

allowed to drag on, it will interfere with the function of these organs

and cause various kinds of diseases. This study applies the Naive

Bayes method to detect anaemia using digital images of the nails and

palms as parameters. The image processing method used in this

research is image segmentation in digital images of nails and palms

so that they are separated from the background using the threshold

method after which the mean values of Red, Green, Blue and their

standard deviation are found. Furthermore, the value obtained will

be processed using the Naïve Bayes classification method to

categorise the palm image data entered into the anaemia or non-

anaemia category. The proposed method achieves 90 per cent

accuracy for the paleness classification of nails and palms pictures.

The proposed paleness screening method can be further fine-tuned to

identify the intensity of anaemia-like pathologies by using a

controlled collection of local images that can then be used for

potential benchmarking purposes.

Abstract

Aluminum is a metal that is widely used for various purposes, from

use for canned beverage packaging to building construction,

automotive, and transportation. Aluminum is widely used because of

its toughness, light weight and rust resistance. The number of uses of

aluminum has an effect on the existence of its waste which will also

increase. Aluminum waste processing has been carried out using the

melting method into aluminum ingots as raw material for the

aluminum industry. Aluminum waste samples come from vehicle and

automotive repair shops. A total of 1.5 kg of workshop waste is cut

into sizes smaller than 7 cm and then melted separately for 500 grams

each using a crusibel furnace (lift-out). The melting is carried out 3

times by varying the amount of flux entered, respectively 0%, 0.2%,

and 0.4% w/w. The flux used in this smelting is Na2CO3 (Borax). The

melting process takes 20-30 minutes and the temperature of the molten

metal pouring is 697-715 oC. The results of the melting of the first 500

grams of waste without using flux resulted in 460.7 grams of ingot and

27.6 grams of melting dross. In melting using a flux of 0.2%, it

produces 437.7 gr of ingots and 61.2 gr of dross. In smelting using

0.4% flux, the ingot weight was 420.7 gr and dross weight 68.1 gr. The

more use of flux in the aluminum waste recycling process using the

melting method, the effect of reducing the resulting ingot weight and

increasing the weight of the dross that is wasted. This is because the

impurities in the ingot have bonded with the flux and migrated to the

waste along with the dross

This study aims to apply the principles of an environmentally

friendly work area. One of the batik home industries, Dinda Hayu

batik, which is located in Munggon Hamlet. Padukuhan Munggon,

Sendangtirto Village, Berbah District, Sleman Regency, Yogyakarta

Special Region, became the object of this research. The leader and

owner of Dinda Hayu Batik is Mrs. Riyo Ety. A high level of sales and

a large profit to be obtained is one of the goals of a business. To

achieve that goal requires maximum employee performance, good

product marketing, and a supportive work environment. This research

discusses how environmental aspects can support employee

performance so that it leads to increased profits that will be obtained

by Dinda Hayu Batik. Environmental aspects are comfortable in terms

of the availability of adequate locations to fulfill the Green Open

Space (RTH) and parking areas. In addition, the comfort of the work

area also greatly affects employee performance. A hot work

atmosphere will make employees sweat more than they should, so

employees will feel tired quickly. Therefore, the solution of providing

a sufficient green open space (RTH) or garden and supported by

smooth air circulation in the work area will make the work area

temperature cool and comfortable. A hot work atmosphere will make

employees sweat more than they should, so employees will feel tired

quickly. Therefore, the solution of providing a sufficient green open

space (RTH) or garden and supported by smooth air circulation in the

work area will make the work area temperature cool and comfortable.

Abstract

Wastewater from small-scale gold processing is discharged directly

into the surrounding rivers, causing mercury contamination in the

river. It is important to know the estimation of the carrying capacity

of river pollution due to mercury to support the improvement of the

river ecosystem. The research objective was to calculate the load

capacity of mercury pollution (Hg) in rivers around the gold mining

and processing area of the people of Pancurendang Village,

Ajibarang District, Banyumas Regency, Central Java. The research

begins with river discharge measurements. River discharge is

measured by referring to SNI 8066: 2015. Water sampling was carried

out at 12 river points with a purposive method that took into account

the location (upstream, middle, downstream) and river

characteristics, according to SNI 6989-78: 2008. Actual mercury

levels in river water were tested at the UGM Integrated Research and

Testing Laboratory (LPPT) with Mercury Analyzer. The results of the

mercury and discharge levels are used to calculate the actual

pollution load. The maximum pollution load is based on the quality

standard of mercury in class 2 rivers, namely 0.005 ppm multiplied by

river discharge. The load capacity of mercury pollution is obtained

from the difference between the maximum pollution load and the

actual pollution load. The results of river discharge measurements at

the research location are quite varied, ranging from 0.0024-2.925

meters/second. In the lower reaches of the river, the width of the river

118

and the river flow is getting bigger, so the discharge is getting bigger.

The actual mercury pollution load at 8 points is undetectable (

Abstract

Groundwater exploration is a method to produce the needs of clean

water. Most of Indonesian people use groundwater for daily

consumption. Groundwater contamination can occur because of

various human activities that produce pollutants. One of the activities

that can affect the quality of subsurface water is the existence of a Gas

Station. Caturtunggal is one of the areas in Sleman Regency which

has a dense population. Caturtunggal has varied activities such as

hotels, restaurants, shopping centers, and education. If there is

pollution due to hydrocarbons, the impact that occurs can pollute the

densely populated area. Geophisycs methods is one of techniques to

explore the groundwater, specially geoelectrical resistivity. The

objective of this research is to identify the exixtences of hydrocarbon

in the grounwater around gas stations using geoelectrical resistivity

method. This research conducted with the methods i.e. observation,

mapping and geophysiscal method, geoelectrical resistivity. The result

from geoelectrical resistivity analysis shows that contamination of

hydrocarbon is not occur in the groundwater. In general, the lithology

of the composing area of the study area consists of loose sediments

with coarse to very coarse grain sizes which are represented by large

resistivity values. At the measuring point 1 to 4 there is no indication

of the presence of groundwater pollution which is represented by the

resistivity value of the aquifer zone in the teilitian area which is still

in the resistivity order of 101 ohm meters. The existence of aquifers in

122

the research area is at a depth of 12 meters to 15 meters. Getting

deeper towards the south. However, the colaboration data is required

to analyze more details about the contamination.

Erosion and Flood Discharge Plans Analysis

on The Capacity of The Dead River Lake

Andi Renata Ade Yudono1, Muammar Gomareuzzaman2


Abstract

Sometimes a development is not in accordance with the carrying

capacity of the land or area designation because it is not in

accordance with the characteristics of an existing area. The dead river

lake in Pondok and Parangjoro villages has various benefits for the

surrounding community, resulting in land conversion that is not in

accordance with its purpose and has a negative impact (erosion) on

the surrounding environment. Therefore, it is necessary to know how

much erosion has occurred in the area around the Dead River Lake,

the magnitude of the planned flood discharge and the potential for

lake water overflow to the surrounding area. The study used several

methods, including the usle method to determine the amount of

erosion, the planned flood discharge to determine the estimated

maximum discharge in several return periods, and spatial to

determine the capacity of the dead river lake. Based on the results per

parameter, it was found that the total erosion in the study area was

87,454,918 tonnes / ha / year or 678.02 m3 / ha / day with an area of

63,971,488 m2. The existence of continuous erosion can cause the

capacity of the dead river lake to be reduced and indirectly it can

cause flooding due to lake overflow on the 7th day for the 25 year

return period, 10 for the 10 year return period, 12 for the 5 year return

period, and 16 for a 2 year return period.

environmental problems that complicates the lives of local people. The

research location is included in drought-prone areas that need to be

further identified, whether including meteorological drought or

hydrological drought. This study focuses on the study of subsurface

aquifer conditions, especially determining the position of the depth

where fresh water is located. The purpose of this study was to

determine the characteristics of the subsurface aquifer and to estimate

the depth of fresh water as a source of clean water. The research

method used is the geoelectrical resistivity test of the Schlumberger

configuration. Data processing and modeling were carried out to

obtain resistivity data that represented subsurface rock types. The

results obtained are the lithology of the area comprising the study

area consisting of fine-grained sediments. The value of the resistivity

range assumed to be the aquifer layer is 20 - 40 Î©m. The indication

of the presence of an aquifer layer is at measuring point 2 with an

indication of the number of aquifers of two layers, namely at a depth

of 12.2 meters and 71.5 meters, and at measuring point 4 with an

indication of the number of aquifers in one layer at a depth of 79.2

meters.

Abstract

Umbulrejo Village, Ponjong District, Gunungkidul is one of the

villages that has both karst and non-karst landforms. The variation of

landforms that exist in this research area affects the quality of

groundwater, either naturally or due to human activities. In the area

obstructed by topography such as Umbulharjo Village, a centralized

water management system is quite challenging, especially those that

use a piping system in its distribution. Hence, a decentralized water

treatment system is required. The direct filtration method as one of

reliable methods in decentralized water treatment system, will be

observed to treat water with the turbidity level of less than 10 NTU

and 10 – 50 NTU. This study aims to analyze the effectiveness of

turbidity removal using the direct filtration method. This research was

conducted by a laboratory experiment. The coagulation, flocculation,

and filtration were conducted in a continues mode during 3 hours. The

dependent varibles measured were turbidity and Hydraulic loading

rates (HLR). The effectiveness of turbidity removal in this experiment

was all good. Better effectiveness was achieved by the filter columns

operated in the lower HLR (2.88 – 3.1 m/h). The HLR was proven

affecting the filter performance thus increase the workability of direct

filtration. While the higher HLR (4.8 m/h) resulted a fluctuation in

effluent turbidity. However, these two HLRs as recommended in the

direct filtration method were excellent resulting the effectiveness of

turbidity removal ranging from 71.7% to 100%. It can be concluded

that the direct filtration can be used in a decentralized water treatment

system.

Abstract

Residents of Dusun Gesikan Rt 04 Panggungharjo, Sewon, Bantul

have not managed household organic waste properly. Household

organic waste management is very important to do to minimize

environmental pollution. This activity aims to provide direction and

assistance to residents to process organic waste into liquid organic

fertilizer (LOF) using the Stacked Bucket method or Tong Kompas as

well as utilizing LOF produced for plants that are planted

independently in each resident's house. Although it has not been

analyzed in the laboratory, the physical characteristics of the LOF

produced are quite good in terms of color, odor, and viscosity.

Indirectly, this activity reduces the dependence of the community on

commercial fertilizers. Also, residents contribute to efforts to protect

the environment so that it is free from waste. It is hoped that the

resulting vegetables will not only be useful for food sources but also

improve the health of citizens in the Covid-19. The community

becomes more productive by empowering household organic waste to

become more useful products.
