Abstract

Erosion Prediction and Planning of Soil Water Conservation at Yeh Ho Watershed in Tabanan Regency The actual problem in the Yeh Ho watershed is the use of land with steep slopes to steep slopes for the use of mixed gardens without conservation measures and poor land cover conditions. The objectives of this study are to predict the magnitude of actual erosion that occurs (A) in the Yeh Ho watershed and to plan soil and water conservation techniques on land units whose erosion exceeds the allowed erosion (Edp) in the Yeh Ho watershed in Tabanan Regency. The method used in this study is a survey/observation method that is taking data in the field and continued with soil analysis in the Soil Laboratory of the Faculty of Agriculture, Udayana University. The stages of the research were carried out in five stages of work, namely: (1) Determination of land units, (2) Field observations and soil sampling, (3) Laboratory analysis and data processing, (4) Erosion prediction using USLE (Universal Soil Loss Equation) method, (5) Determination of allowable erosion and soil and water conservation planning if the actual erosion exceeds the allowable erosion. The results showed that erosion that occurred in the Yeh Ho watershed was classified as very mild to mild at 0.06 to 34.89 tons/ha/yr. Very light erosion occurred inland units 1, 2, 5, 6, 7, 8, 10, and 13 with an area of ??11,096 ha with erosion that occurred in the range of 0.06 to 3,226 tons/ha/yr, mild erosion occurred inland units 3, 4,9,11, and 12 with an area of ??4,868 ha with erosion that occurred from 4.93 to 52.57 tons/ha/year. The land that requires conservation measures covers 1,717 ha from the area of ??the study area and the land that needs to be maintained is 11,096 ha. It is expected that the people in the Yeh Ho watershed in Tabanan Regency can pay attention to land management by maintaining and conserving so that the actual erosion that occurs does not exceed the allowable erosion.

Abstract

Mapping of Land Drought in El Nino Phenomenon 2002, 2009 and 2015 in Bali Province Using Remote Sensing Technology and Geographical Information System Land dryness caused by the El Nino phenomenon in an area has a major impact on land productivity. The objectives of this study are (1) to compare the level of land dryness based on the El Nino phenomenon in 2002, 2009 and 2015, and (2) to determine the impact of El Nino on food crop production in Bali Province. To achieve this goal, this study uses Terra MODIS images. Drought condition is evaluated using vegetation greenness and air temperature parameters. Normalized Difference Vegetation Index (NDVI) and Vegetation Condition Index (VCI) are used to predict the vegetation greenness, where as Land Surface Temperature (LST) and Temperature Condition Index (TCI) are utilized to estimate the air temperature. Finally, Vegetation Healthy Index (VHI) is calculated based on value of VCI and TCI. The results shows that the El Nino phenomena in 2002 is the strongest dryness in Bali Province followed by the El Nino in 2015 and 2009. Most of the drought is spread over coastal area of Bali Province. There is the time lag around 6 months between decreasing of rainfall and appearance of drought symptoms. The total production of food crops in 2015 is the lowest, namely 1,032,067 tons, compared with production in 2002 and 2009 that is 1,127,452 tons and 1,252,443 tons respectively. However, statistically El Nino phenomena has no significant effect on food crop production. This is caused by the rice field irrigation sistem in Bali Province is still well maintained and the ability of farmers to mitigate the impact of drough on agriculture production.
