【 摘 要 】

The research conducted in order to find out how the susceptibility for landslides in the village of Belandingan, Songan A Village and Songan B Village. Scoring and overlay method used to determine the results of landslide susceptibility in the study area. Parameter used as the basis for overlay and scoring are soil types, rainfall data, structural geology, landform, slope and land use map. From the overlay result, 41 land unit were mapped on the research area. Based on scoring and GIS analysis, there are 4 classes of landslide susceptibility including not susceptible, low susceptibility, moderate susceptibility and high susceptibility. Most area of study area are are included as low susceptibility and medium susceptibility. Meanwhile high susceptibility mainly concentrated on the ancient caldera on west part of Batur Lake. Belandingan, Songan A and Songan B villages have various levels of landslide susceptibility, starting from this non-susceptible category, covering land units 34 and 39. Low susceptibility on land units 26, 29, 25, 23, 21, 38, 3, 12 and 11. While on land units 36, 30, 31, 32, 14, 15, 16, 17, 19, 4, 20, 40, 24, 6, 13, 2, 37, 7, 8, 9, 27.10, 22, 41, 1.5 and high susceptibility on land units 33, 18, 35, 28. The no susceptibility class mainly located in Songan A and Songan B Village with total area 94,405 Ha. Low susceptibility class are located mainly in Songan A Village with small amount in Songan B Village with total area 1196.768 Ha. Moderate susceptibility class located in all with total area 1866.346 Ha. High landslide susceptibility class located mainly in Songan B Village with small amount in Belandingan Village and Songan A Village with total area 339,979 Ha.
