Abstract

Kemuning Lor is one of the villages in district of Jember that is prone to landslides, especially when the intensity of rainfall is high. Previous research on the classification of landslide vulnerability level which was analyzed based on socio-cultural, economic, physical and environmental parameters, showed that the level of vulnerability in the PTPN XII Kebun Renteng Afdeling Rayap which includes Kemuning Lor village in medium class. This condition contradicts the actual facts which show that Kemuning Lor village has a high level of vulnerability based on data on the number of landslide disasters during the last 10 years. The purpose of this study was to conduct spatial analysis and mapping of landslide-prone areas in Kemuning Lor Village. The method used to determine the location of landslide-prone areas is the Storie Index, which will be used in the Geographical Information System program. Before the overlay process is carried out, several parameter maps (slope and rainfall maps) will be made and scores will be given on each criterion from the parameter map. After doing the store index and getting the values in the form of numbers, the next step is to convert this range value into several levels as needed.
