Abstract
Landslide is a disaster that occurs in Jlantah Sub watershed during rainy season. Landslide problems arise in the study area because that area has sloping topography and based on data from related agencies, landslide often occurs, so evaquation route is needed. The aim of this research are to map spatial distribution of landslide vulnerability level and to determining the effective evacuation route in Jlantah Sub Watershed. The research method that used is skoring of parameters that used. The sampling method that used is purposive sampling of landuse based on the landslide vulnerability class. The parameters that used in this study are rainfall, slope, geology type, soil type, and landuse. Identification of vulnerability level of landslide have 3 results, that are high, medium, and low class. The highest level og landslide are located in Jatipuro, Girimarto, Manyaran, Nguter, and most of Jatiyoso district. Medium class of landslide are located in Jatipuro district, Jumapolo district, most of Wonogiri regency, and some of Sukoharjo regency. Low class of landslide are located in most of Sukoharjo regency and some of Wonogiri district. Based on the result of spatial analysis of vulnerability level of landslide, it can be used as an early warning system for general public that live in prone area. As a form of application, an evacuation route was made by using least cost path analysis technique. Through this technique , an effective evacuation route will be formed. The technique was chosen because it can effectively show the closest evacuation route at the lowest cost. That technique can help the public about evacuation process. Keywords: Landslide, Evaquation Route, Least Cost Path Analysis
