Abstract

Application of Geographic Information Systems and Remote Sensing for The Study of Landslide Potential and Susceptibility in Tukad Buleleng Watershed, Buleleng Regency Landslides are a ground movement event that descends the slopes and is almost found in every major watershed upstream, due to steep topography and high rainfall. Tukad Buleleng watershed is one of the watersheds with a stretch of rolling land and hills so that it has the potential for landslides. This experiment was been conducted from January to Agust 2020. The aims off this research were to find out the potential lanslide and the level susceptibility to landslide. The method used to determine the potential for landslides was a scoring method referring to PSBA UGM (2001) by overlapping the parameters of the causes of landslides were rainfall, slope, land use, soil types, structural of geology, and landforms maps. Landslide-prone areas were obtained by overlapping landslide potential map, road network map and residential area map. The results showed that the potential landslide in Tukad Buleleng watershed had many categories from not potentially up to high potential. The area had no potential of landslide were widespread in the downstream watershed covering an area of 1,733.94 ha 51.61%, low potential category of 165.08 ha 4,91%, the medium potential category of 77.24 ha 2,32%, and high potential category spread over the upstream part of the watershed of 1,382.87 ha 41,16%. The distribution of susceptibility was seen from administrative boundaries, Sukasada administration area that covered Wanagiri, Pegayaman, Gitgit, and Padangbulia villages.

Abstract

Analysis of Water Carrying Capacity For Domestic Clean Water Needs in Gianyar and Ubud District of Gianyar Regency Water is the main needs used sustainably. The needs of water always increases in line with the growth of the human population. The increase of water needs for domestic compels a region to maintain the availability of water in order to support the clean water needs. The aim of this study was to found out the water carrying capacity to fulfill the need of clean water of domestic in Gianyar and Ubud sub-districts, Gianyar regency. The research was done using descriptive quantitative method and to determine the number of respondent using stratified random sampling method. The water needs for domestic in Gianyar sub-district is 2,671,391.2 m3year-1 and the potency of water availability was calculated based on the surface water is 513,232.9193 m3year-1; groundwater recharge is 653,205.5337 m3 year-1; and the groundwater basin is 22,000,000.16 m3 year-1. The water needs for domestic in Ubud sub-district is 2,111,598 m3 year-1 and the potency of water availability was calculated based on the surface water is 476,395.4871 m3 year-1; groundwater recharge is 582,261.1509 m3 year-1; and the groundwater basin is 18,000,000.99 m3 year-1.Carrying capacity index of surface water in Gianyar sub-district is 0.19; groundwater recharge is 0.24 and the groundwater basin is 8.23. Carrying capacity index of surface water in Ubud sub-district is 0.22; groundwater recharge is 0.27; and the groundwater basin is 8.52. Based on the analysis, it was found that the status of surface water and groundwater recharge carrying capacity in Gianyar and Ubud sub-district was deficit (water supply < water demand), however carrying capacity of groundwater basin was surplus (water supply > water demand).
