| Summary: | 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 mitigation
