(GIS) in Ho Watershed, Tabanan

Regency

Introduction

Corn is an important food crop for human and is the second food crop commodity after rice.

All parts of the plant can be used for various purposes such as raw materials / processed materials

for cooking oil, corn-starch, ethanol, dextrin, acetone, glycerol, adhesives, textiles and organic acids

for biofuel.

This study aims to evaluate the suitability of the use of corn in the Ho River Basin, to know the limiting

factors for the suitability of the use of corn land and to determine or provide directions for the use of

corn land in the Ho River Basin.

The research location was carried out in the Ho River Basin, Tabanan. Administratively the Ho water-

shed is located in two sub-districts in Tabanan Regency, Bali, Indonesia, namely Kerambitan and

Penebel sub-district. Astronomically, the DAS Ho is located at position 115o 01 '26.3 "- 115o 09' 04.9"

East and 8o 16 '30.2 "-8o 34' 03.7" South.

Methodology

Before physical data collection activities are carried out in the field, detailed

land units are overlayed from slope maps, climate maps, soil type maps and

land use maps using GIS software. Land unit map functions to direct

sampling in the field. Each land unit is sampled proportionally to its area.

Sampling is done by transect in a sloped area and with a grid system in a flat

area. Soil samples are taken in layers at a depth of 0 - 30 cm, whereas to

determine the effective depth is continued up to a depth of 150 cm for soils

classified as deep or until lytic contact in shallow soils.

All data taken from the drilling results are then evaluated in the field, to obtain

representative samples. Each soil sample then analysed in a laboratory to

determine the characteristics of the soil. The characteristics of the soil to be

analysed are Soil texture, Organic C, N- Total, P- available, K- available,

Cation Exchange Capacity (CEC), Base Saturation (KB), soil pH, Soil

permeability, and salinity.

Result and Discussions

Delineation of land units is done through overlapping 4 types of maps, namely land, climate, slope and

land use maps.

Result and DiscussionsLand Unit Analysis

Land units is mapped through

overlaying 4 types of maps, na

mely land, climate, slope and la

nd use maps

There are six land units and six

samples to be anaysed in the

lab

Result and Discussions

Based on the analysis of soil samples in the Laboratory, it shows that the

physical properties of the soil samples shows that soil texture dominated by a

rather fine texture, medium texture (clay). Drainage conditions range from

rather poor (ABr) to bad (Br). Coarse material, and surface rocks are found in

the the upper stream of the Yeh Ho watershed, which are located in the land

units II and III in Mangesta Village and Penatahan Village of Penebel Sub-

District. Rock outcrops are not found in all irrigated rice fields in the Yeh Ho

River Basin. The slope of the study site ranges from 2% (flat) to> 45%

(Steep). Chemical properties and soil fertility including soil pH ranges from

slightly acidic to neutral, salinity levels range from low to very high, C-organic

ranges from very low to high, soil CEC varies from moderate (21.79 me/

100g) to high (30, 59 me/ 100g), base saturation ranges from moderate

(46.15%) to very high (107.21%). N-total is classified as low (0.18%) to

moderate (0.35%), P-available is classified as very low (0.56 ppm), to high

(10.03 ppm); and K-available is high (120.58 mg / 100g) very high (334.08

mg / 100g).

Land Suitability Analysis

Result and Discussions

Based on agro-climate data which includes annual mean temperature, rainfall from the Meteorology Climatology and Geophysics Agency of the Central Tabanan Region. Average annual temperatures range from 21.5-28.9 0C, humidity ranges from 58-82%, and annual average rainfall ranges from 1000 mm - 2000 mm. Based on Bali's geological map data, the Yeh Ho watershed has soil types that are dominated by Yellowish Brown Latosol soil type, then followed by Regosol Brown Gray and Andosol Brown Gray soils.

The landform of Ho watershed is dominated by the form of a undulating to hilly sloping area, then followed by hilly to mountainous region in the upstream area of the Ho watershed, as well as the flat area form in the downstream area of the Ho River watershed.

Result and DiscussionsThe actual land suitability for corn is classified as non-suitable (N) and marginally suitable (S3) with the limiting factors are slope, erosion hazard, soil drainage and nutrient availability (P-available). Potential land suitability for corn is classified as suitable 2 (S2) to marginally suitable (S3) with limiting factor is temperature that is higher than required, especially for Berabanand Tangguntiti areas with limiting factors are slopes, erosion hazards and nutrient availability (P-available). The suitability of potential land for corn is quite suitable 2 (S2) and marginally suitable (S3) with limiting factors in temperature, slope and erosion hazard. Several efforts to improve the existing limiting factors are improvement of drainage, addition of P-fertilizer, terracing treatment for erosion prevention.

Conclussions

The actual land suitability for corn in Ho Watershed is classified as non-suitable (N) and margi-

nally suitable (S3) with the limiting factors are slope, erosion hazard, soil drainage and nutrient

availability (P-available). Potential land suitability for corn is classified as suitable 2 (S2) to mar

-ginally suitable (S3) with limiting factors are temperature slopes, erosion hazards and nutrient

availability (P-available).

Several efforts to improve the existing limiting factors are improvement of drainage, addition of

P fertilizer, terracing treatment for erosion prevention.
