Abstract

Plaosan sub-district is one of the sub-districts where landslides often occur, landslide events that often occur are influenced by the topography of Plaosan sub-district which has varying slopes. Based on data collected from BPBD in 2020 alone, Plaosan District has a number of landslide disasters of 7 landslides that are spread in Plaosan District. In the study of landslide susceptibility analysis based on geographic information systems by scoring and overlaying landslide susceptibility parameters. The objectives of the research are. Knowing and analyzing the distribution of landslide susceptibility levels in Plaosan District, Analyzing the dominant factors influencing landslide susceptibility in Plaosan District,. The method used is a survey using land units as the unit of analysis, sampling using the Stratifed Method with land units as strata. The method of data analysis is tiered overlay analysis, dominant factor frequency table analysis, and spatial suitability overlay analysis. Based on the research, it was found that. Landslide vulnerability has 3 classes, namely low, medium, and high. Medium vulnerability class with 27 land units namely V3-IV-AND-H, V3-IV-AND-SE, V4-III-AND-H, V4-IV-AND-H, V5-I-AND-TE, V5- III-AND-H, V5-III-AND-T, V5-IV-AND-H, V5-IV-AND-PE, V5-IV-AND-SE, V5-IV-LC-T, V5-V- AND-H, V5-II-AND-PE, V5-II-AND-T, V6-I-RK-T, V6-I-RK-SA, V6-III-LC-P, V6-III-RK- P, V6-III-LC-SA, V6-III-LC-T, V6-IV-LC-P, V6-IV-LC-SA, V6-IV-LC-T, V6-II-RK-PE, V6-II-RK-P, V6-II-RK-SA. The high vulnerability class has 6 land units V3-V-AND-SE, V5-IV-AND-SA, V5-IV-AND-T, V5-V-AND-SE, V5-V-AND-T, V6-IV -AND-T. The low vulnerability class has 3 land units V6-I-LC-SA, V6-III-LC-PE, V6-II-LC-PE. The dominant factor for landslides is land use and the slope of the slope
