Construction of tower foundation

Foundation is reinforced concrete construction to tie foot towers (stub) to ground. Tower foundation types where soil conditions various according to tower site is located and load to be covered by tower. Tower foundation is designed to bear tensile load is stronger/larger than suspension towers type. Typical foundation for Rajamandala 150 kV Transmission is as presented in Figure 2.3.

Figure 2.3. Foundation Typical For 150 kV Transmission Line Tower

On land that has been released for in advance tower site conducted land clearing. After land clearing excavations conducted by width of base as planned. Next stage is installation of stub. Stub is bottom of tower legs, installed together with installation of foundation and fastened together with foundation. Top of stub appears on surface of ground about 0.5 to 1 meters and cement and painted to be protected is not easily corroded.

Concrete work casting involves mixture of cement, sand, gravel and water with a certain ratio in mold plate steel or wood. To establish a solid foundation of tower needed to be able to bear burden of tower and its equipment, including moments that will result. Foundation of tower was designed and built based on type of tower that is: corner towers, strained towers and tower end. At time of construction and installation of tower foundation, land area must be able to meet broad work space.

uncuing (Cacomantis sepulcralis), bamboo cikrak (Abroscopus superciliaris) and kite (Hirundo tahitica). There are also other types of seed suckers, like sparrow (Passer Montanus), Scaly-breasted (Lonchura leucogastroides, L. punctulata), and other groups are fruit eaters, such as chili Java bird (Dicaeum trochileum), tikukur (Streptopelia chinensis), and finches (Pycnonotus aurigaster), as well as small vertebrates and fish eaters, like cekakak (Halcyon chloris).

From mammalian class listed fauna species are omnivores, ie rat (Rattus sp) and carnivores is careuh (Viverriculata malaccensis), as well as sero (Aonix cinera). In addition to mammalian class, in this location fauna species listed from class of reptiles, such as water snakes (Natrix sp) and python (Python reticulata)

b) Diversity, Distribution and Abundance Bird Type Diversity of fauna type that includes class Aves seen from number listed 17 species with a diversity index of Shannon & Wiener 2.749; including not high. This is caused by low diversity of habitat types and species of flora habitat constituent which is generally a cultivated crop.

Based on results, with IPA method (Indices Ponctuels Abondance) several bird species highest spread in around location tower site plan are swallow (Collocalia esculenta), sparrows (Passer Montanus), and Scaly-breasted Java (Lonchura leucogastroides) with frequency relative of each respective 19.6%, 19.6% and 16.1% (Table 2.14). This is understandable given swallows are insectivorous birds which are commonly found around water area / field, whereas sparrow and Java Scaly-breasted seed eater birds are commonly found around garden / fields, shrubs, and residential areas. Most of other birds found in vicinity of 150 kV HVTL tower site has a low spread.

Species diversity, species distribution and abundance of birds in the vicinity of 150 kV HVTL tower site plans are presented in Table 2.20.

Total 96 100 Source : Primmary Data, 2011From table 2.37 above can be explained that 100% of respondents had electricity. Existence of this power facilities, there have been about 1-5 years ago (100% respondents). Installed capacity varied, ie, between 450 VA - 900 VA (83% respondents) and above 900 VA (17% respondents). Existing capacity is used only for one home (100% respondents). When there is no electricity or power outages, residents use alternative energy ie oil for lighting or household activities (100% respondents). Similarly, in need of water for daily life, residents have had wells in each home (100% of respondents), which is used both for washing, cooking, bathing, drinking (100% of respondents). Its waste water directly channeled into gutters that circled around their home (100% of respondents). In waste management, 100% of respondents claimed to burn it in front of their homes or were collected in one spot for garbage disposal and then burned. 100% of respondents, admitted if there is a sick, first aid is carried out using traditional medicines made from leaves or plants that are around the area. However, if no result then the population will usually visit health center closest to their homes. Besides above facilities, there are also access roads that feel people are still far from expected. From interviews with respondents found fact that 60% of respondents considered that existing roads around the region have damaged roads, 30% responded that in general is broken, and other 10% rate on a path generally in decent condition to be passed, both by vehicle and road users.

- Public perception of activity plan

In public perception and attitudes towards activity plan can be drawn that 100% of respondents had been aware of this development plan. 53% of them know of field staff who conduct survey, 47% were aware of rumors that developed in community. Furthermore, 100% of respondents answered approve tower-

building activities in its territory. Of which 73% of respondents considered that construction of transmission is important for national development and 27% of respondents admitted very important. In terms of security of 150 kV transmission line is 83% and 17% saw other safe looked pretty safe. This opinion is a bit much has been affected by the presence of important figures from people who considered a role model for citizens, which in this case 67% answered RW is a person who deserves to be a role model. 20% of government officials or village, and 13% are religious scholars / clerics. Of 30 respondents, 70% support and 30% are very supportive of this action plan and will maintain existing tower at nearby territory. Addition of 30 respondents agreed that 57% of admitted and 43% strongly agree to not interfere with presence of 150 kV transmission lines. Besides, 93% answered disagree and 7% did not agree when his residence near / adjacent to tower site. Even those assessing agree 100% that existence tower will not interfere with daily activities of citizens. If there are obstacles in implementation, 57% strongly agree and 43% agree, that joint consultation is best way out. Likewise with land determination and land prices, at which 77% answered agree and 23% strongly agree, to be deliberation in order to achieve mutual agreement.

Community expectations:

In the recruitment of workers, both during construction of infrastructure, at time of mining operations as well as maintenance, is expected to involve the local community, to be a worker.

Condition of village roads are small and rocky ground, where rainy season as at time of survey is done, turn into a street full of mud and water, residents perceived as an inconvenience. Therefore, asphalt road improvement Village / hotmik so they crave.

Land acquisition price of should be done in a transparent, open to all parties, both the communities, initiator or government.

d) Public health component

Main health problems in Haurwangi Subdistrict is limited health facilities andinfrastructure as well as limited number of medical workers and leading medical health services provided to people feels not maximized. Many people who experience pain, and often times they are treated with traditional medicines. However, if disease is considered not improved, residents who experienced pain will soon be treated to health care institution that is closest to location where his

CHAPTER III ENVIRONMENTAL IMPACT WILL HAPPEN


| III - 1

1) PRE-CONSTRUCTION STAGE

Activities at which is expected to cause impacts on environment is a field survey activities and procurement / land acquisition.

a. Field Survey

Income Level

Field survey activities, especially at time of the survey related to social, economic and cultural, more or less will involve residents around project. This will have an impact on changes in income level citizens, especially those that are directly involved in the survey. Number of people involved is relatively small at around 5-6 people.

Communityrestlessness

Field survey activities cause curious communities about planned 150 kV transmission activities, such as location of tower site, planning transmission lines, as well as negative impact of 150 kV transmission to health. Lack of information communities action plan adopted by potentially cause public unrest.

b. Land procurement

Community restlessness

Categorized types of negative impact, because activities of land acquisition for tower site and compensation for ROW Transmission potentially cause public unrest will indemnity and compensation that are not appropriate and not transparent.

Land area to be released for 150 kV transmission tower site of9.850 m2.While compensating for ROW will be given to owners of stands (plants/vegetation) along 150 kV Transmission is7,65 km in width corridor 20 m.

Impact of activities to public unrest is quite large because number of landowners tower site quite a lot. Impact of activities of public unrest lasted

3ENVIRONMENTAL IMPACT WILL HAPPEN Chapter


| III - 2

a while, but if not handled properly impact can last a long time so it can disrupt level of public acceptance of planned 150 kV transmission activities.

2) CONSTRUCTION STAGE

a. Procurement and mobilization of labor

Income level

Labor mobilization activities will absorb local residents for 60% of total labor of 80 people required. Number of job seekers in study area in 2007 is as much as 3446 people. So with construction stage can reduce number of job seekers at 1.45%.

Impact positive classified because it can reduce unemployment. Create employment opportunities for 1.45% predicted as impact is small. Impact has a derivative form of increased accommodative attitude of communities towards the project so important positive impact categorized.


Mobilization activities equipment and materials to or from project site will have an impact on noise and dust. Dust and noise pollution, based on measurement results still meet required quality standard that is not so detrimental to health of local communities and comfort. Nevertheless, communities located in study area are not bothered by mobilization of equipment and materials as distance between access roads to settlements is quite far apart.

b. Mobilization of equipment and construction materials

Noise

Impact on noise, caused by mobilization activities of equipment and construction materials by vehicles used. Sources of noise generated by use of such vehicles including intermittent type. Approach taken is a voice that emitted an average vehicle is taken as 80 dBA at source, average vehicle speed is 40 km/h, then forecast distribution of noise at time of mobilization activities of equipment and construction materials at a distance of 20 m from source for 56, 5 dBA and at a distance of 50 m from source of 46.9 dBA. Based on measurement results of at measurement site, average noise level of 38.9 - 51.9 dBA. Based on Kep MenLH Number: KEP-48/MENLH/11/1996, about Noise Level standard, still meets noise level of standard for residential (55 dBA).


| III - 3

Road damage level

Mobilization activities categorized as negative impacts on facilities and infrastructure of economy because it could potentially cause damage to roads, especially on rural roads are impassable mobilization.

Mobilization of equipment and materials for 150 kV transmission construction will use a truck capacity of between 1.5 to 5 tons with ritasi 4-5 vehicles per day. Based on interviews with communities in the study of the extent of damage to roads, as much as 90% of respondents stated condition of damaged roads in generally.

Potential damage to roads is expected to occur on rural roads with ground/pavement stones. Impacts will last for 150 kV transmission construction activities are estimated to ± 5 months. With impact spread along mobilization of equipment and materials for 150 kV transmission construction.


Types of impacts are categorized as negative because of convenience that communities living around planned 150 kV transmission construction site will be disturbed by noise and road damage.

Potential impacts to convenience of communities expected and will last for 150 kV transmission construction activities are estimated to ± 5 months. Region is concentrated along pathway impact spread mobilization especially people living in vicinity of 150 kV transmission construction.

c. Construction of foundation and tower assembly

Noise

Tower assembly is done manually, where components are assembled under tower, then gradually carried out by using mounting bolts and nut. After assembly, removal of tower using a crane and a pendulum to keep tower upright 100% assembled.

By analogy with installation of 150 kV Transmission towers in South Bandung area, relative assembly manually does not cause noise, because components are assembled is so material, so it does not require further physical processes in addition to installation. Thus impact of construction and assembly of tower foundation to increased noise does not include negative impact.


Impacts development activities and assembly of tower foundations negative categorized by disruption of communities convenience by pile material and


| III - 4

soil excavation foundation that will affect cleanliness of neighborhoods, especially in times of rain.

Impact scale is relatively large because about 60% of respondents located in vicinity of activities are comfortable with environmental conditions before any development 150 kV transmission tower foundations activity.Impact on public perception lasts for tower foundation construction activities and assembly of 150 kV towers are estimated for ± 2 months.

Environmental sanitation

Impact type categorized negative on environmental sanitation because of decline in environmental cleanliness associated with waste remains of vegetation clearance, residual pile material, as well as residual excavation of foundation soil.

Scale impact estimated is relatively small because most of tower foundation construction site and assembly of 150 kV transmission towers are far away from residential areas. Impact on public perception lasts for tower foundation construction activities and assembly of 150 kV towers are estimated for ± 2 months. Distribution of impact, especially on tower site locations around residential areas.

d. Conductor stringing

Flora

Impacts type on flora components categorized as negative because decline in number of stands of trees along the stringing line 150 kV transmission conductor cable.

At the time of cable conductor stringing (stringing) as long as ±7,65 km should not be exposed to the ground, wounds or dirty because it will cause corona effect when given voltage. For safety cable so 150 kV Transmission Conductor vegetation with a height of 5 m will be cut down.

Garden soil that passes through a conductor cable consisting of a mixture of garden crops/annuals and perennials such as bamboo rope(Gigantochloa appus) and jenjen(Albizia falcata). Impacts activities categorized as small as constituent flora garden vegetation mostly crops/crop and absence of plants and rare or protected.

Fauna

Impacts type on fauna components categorized as negative because declines of fauna habitat and changes in fauna distribution especially class Aves (birds). As mentioned above, potential loss of fauna habitat gardens are concentrated on land that passes through cable conductor.


| III - 5

Scale impact on decline of fauna considered relatively small due to small number of stands will passes through 150 kV transmission conductor cable. Changes in the distribution of fauna is only temporary because of high mobility of types of birds to find a habitat type that is still pretty much around location of activities. Possibility of a further decline of fauna species due to hunting or fishing carried out by workers during 150 kV transmission construction activities.


Conductor cable stringing activities negatively impact public unrest. These impacts arise from land owner used for placement of equipment and stringing material that is so big and so many feared would damage crop. Besides disruption of convenience most of population passes through conductor wire for fear of damage inflicted at time of stringing activity conductor cable.

3) OPERATIONAL STAGE

a. 150 kV Transmission Operation

Space, land and soil

Categorized types of impacts negatively on land space and soil for causing limitations in land use and space use, especially below 150 kV Transmission.

Limitations of land use and space, especially in gardens and settlements. For public safety and security operational 150 kV Transmission minimum vertical clearance of trees and buildings on conductor cable no more than 5 meters.

Rule of 150 kV HVTL free space makes building owner can not develop building into vertical direction. So that land under transmission lines will decrease resale value. Besides information about influence of magnetic fields and electric fields that could endanger human health to be cause of reluctance of people to own land under a 150 kV Transmission.

Length of 7.65 km and a width of 20 m wide corridor of land under 150 kV transmission by 15.3 ± Ha. When compared with a total area of 17,309 km2 of study area below 150 kV Transmission are limited in utilization and use only 0.88% of total study area.

Impact of predicted large enough for a long time, namely during technical life of Rajamandala 150 kV Transmission. Region concentrated impact spread on land that is under 150 kV Transmission.


| III - 6


Operating Rajamandala 150 kV Transmission Activities predicted to negatively affect public unrest (especially communities adjacent to the lane). Unrest is due to lack of information about negative influence of electric and magnetic fields on health.

Based on monitoring results conducted by PT. PLN (Persero) in 2005 showed that average electric field strength of HVTL activities by 1.28 kV / m and for a magnetic field of 0.0032 milli Tesla, measurement results are still below threshold WHO limit of 5 kV / m for electric fields and 0.1 milli Tesla for magnetic field.

Results also indicate that there is no significant correlation between health problems and exposure to electric and magnetic fields. Although results of these studies showed no significant relationship between health problems with induction electric field and magnetic field. But because it has raised fears in community (public concern) then potential negative impacts arising from the operation of relatively large 150 kV Transmission of public unrest.

b. Maintenance of 150 kV transmission

Income level

Rajamandala 150 kV Transmission maintenance activities predicted positive impact on income levels. This impact occurs because during execution of maintenance activities require some labor to job cuts mainly stands of trees so as not to enter free space.

Workforce will be recruited from local population about 10 people. When compared with number of job seekers in study area for 3446 people so 150 kV Transmission maintenance activities would increase revenue approximately 0.29% of job seekers in study area.

Size of impact is relatively small because amount of labor involved 150 kV Transmission activities are few in number. Impact of temporary employment which only lasts for maintenance activities.

Community accommodative stance

Types of impacts are categorized positive attitudes and perceptions of society. This happens because people assume that e 150 kV transmission are monitored and supervised to prevent unwanted risks such as theft that resulted in collapse of iron tower tower brace, possibility of landslides around tower foundation, and existence of stands of trees that exceed the free space.


| III - 7

Community concerns on security level of 150 kV transmission can be suppressed in presence of maintenance activities. So that will bring a positive perception of public acceptance of existence of 150 kV Transmission.

Thus maintenance of 150 kV Transmission potentially quite large on positive reception of community, especially for communities adjacent to Rajamandala 150 kV transmission line.
