ANALISIS RISIKO BENCANA DAN MITIGASI LONGSORLAHAN DI KECAMATAN SUKASADA, KABUPATEN BULELENG, BALI (kasus longsor di sepanjang jalan menuju kawasan pariwisata)

The research, entitled risk analysis and disaster mitigation of landslide in sub-district Sukasada, Buleleng, Bali (cases of landslides along the road to the tourism) done with some purpose namely: (1) knowing the level of landslides hazard, (2) knowing the level vulnerability of the elements at risk, (3) knowing the level risk of landslide, (4) provide input appropriate mitigation landslide in the research area. The method used in this research based on AGSO consept, 2001. Preparation of landslide hazard map, vulnerability, and risk of using spatial analysis of ArcGIS and matrix system, with the rain, slopes, soils, land use, geology and geomorphology. Scoring and weighting used in the determination of hazard and vulnerability. Sampling method in this study using the method of stratified random sampling based on the landslide hazard zone in the area of research. The data analysis methods used in this research is descriptive qualitative analysis. The results of this research can be described as follows: (1) the level of landslide hazard in the central part of the region that includes the village of Sukasada Sub-district Ambengan, Gitgit, Pancasari, and Wanagiri with the highest score from 350 to 440. (2) the level of vulnerability (physical, social, economic) which is the highest in the village of Pancasari and Pegayaman with the highest score from 0.7 to 1.0. (3) the highest risk landslide disaster spread in southern sub-districts Sukasada viilage Gitgit, which includes Wanagiri, and Pancasari through results in an accumulation matrix with the system. (4) some mitigation effort input obtained from various backgrounds, such as making retaining walls, slope drains, signs the danger of landslide, and plans for disaster-based curriculum in high school and college by considering the conditions and the location of each point of mitigatio
