Abstract

The research location is located in 4 ditricts, that is Leuwisadeng, Leuwiliang, Cigudeg, and Rumpin, Bogor Regency, West Java. This area has a morphological hilly, sloping, and has a higher level of rainfall than other regions making it vulnerable to landslides. This study aims to analyze the level of landslide vulnerability and types of landslides that develop in each of these areas using fuzzy logic method and kinematic methods so that appropriate ways to tackling landslides will be found. Based on the results of the analysis after passing the fuzzy overlay using the help of ArcGIS stage using 5 parameters namely soil type map, altitude map, slope map, land cover map, and lithology distribution map to obtain a map of landslide hazard level which has 4 classes of vulnerability, including hazard class vulnerable, low hazard class, moderate hazard class, and high hazard class. In addition to describing the level of landslide vulnerability using the fuzzy logic method, the study will observe various types of avalanches/slope failure associated with geological structures so that it can result in a discontinuity in a rock mass. The slopes used as the location of the study amounted to 6 slopes divided into each region. The results of the kinematic analysis using the contouring method in which landslide data were grouped using the help of Rocscience Dips v.5.1 software found 3 different types of landslides, namely circular landslide type, wedge landslide type, and toppling landslide type. Based on the results of the analysis, there are several ways to prevent landslides, namely making waterways on the slope surface, weighting the slope geometry, monitoring slopes regularly to find out the existence of extreme soil movements, and emptying the slopes from human activities, where if initial symptoms of land movement or landslides have appeared.
