Abstract

Landslide in the Southern part of West Java Province, Garut regency in upstream Cimanuk River become a disaster for the population and its economic activities. The region is surrounded by active volcanoes, general condition of land topography is bumpy, hilly and mountainous, weathering the soil and high rainfall accumulatively make this region is very potential to landslides. SINMAP is an additional program of ArcView software developed by Pack, Torboton, and Goodwin at Terractech Consulting Ltd, Utah State University in 1998. The purpose of this research is to analyze the potential areas of landslide disaster in Cimanuk River Basin, Garut regency, West Java with Stability Index Mapping (SINMAP) method. The variables used are rainfall, soil type and slope. In addition, this study also using spatial analysis techniques with overlay between the potential that is validated with the location of landslide. The results showed areas with potential classes: (1) 57.8% of Ci Manuk Hulu Flow Area in stable class; (2) 21.8% in low potential class; (3) 2% in the medium potential class; and (4) 18.3% in high potential class.
