Abstract

Landslide is one of the most common disaster in Bogor City and Bogor Regency. BNPB stated that between 2013-2018 there are 44 landslides with death toll of 68 persons. Therefore, it is important to generate map to identify landslide susceptibility in research area. In this study, we try to create landslide susceptibility map of Bogor area (Bogor Regency and Bogor City) using Analytical Hierarchy Process (AHP). We use various factors to identify landslide susceptibility, including slope curvature, slope gradient, topographic wetness index, slope aspect, elevation, stream power index, distance to river, river density, distance to lineament, lineament density, lithology type, soil type, normalized differential vegetation index, rain intensity, land cover, distance to road, and building density. Various factors above are derivative from openly accessed data of Digital Elevation Model (DEM), landslide distribution, Bakosurtanal Map, Landsat 8 Imagery, engineering geology map, rain intensity data, and soil type map. After all, input data collected, the landslide susceptibility map is created using the AHP method. To validate the result, Receiver Operating Characteristic (ROC) applied, the value of the area under the curve (AUC) to determine the success rate of the AHP method is 0.834, this value represents that the landslide suscepbility map produced by the AHP method is a good model.
