Almost all of landslide in Indonesia, especially in West Java, occurred in area with volcanic sediment. Some of them are occurred in Bogor area. The controlling factors that can affect landslide susceptibility area are rock lithology, slope, and land use. In the circumstance when data is insufficient, contain factors causing the landslides used to obtain landslide susceptibility analysis by using the fuzzy logic approach. Therefore, the aim of this paper is to know the landslide susceptibility condition of the research area. In this study, methods used consist of field method to collect geological structure and lithology data also studio method with fuzzy logic to generate the mapping parameters of landslide susceptibility (lithology, geological structure, slope, and land use). The result shows that research area divided into three landslide susceptibility zones, i.e.: (i) non-susceptiblity zone, (ii) low susceptibility zone, (iii) moderate susceptibility zone. The susceptibility area is an area with more massive geological structure and high angle of slope with lithology consist of tuff. The results of landslide susceptibility are useful for the prevention and mitigation of landslide hazards, and appropriate planning for future land use and construction in research area.
