Mapping the Semeru lahar-flood hazard of Supiturang Village using the analytical hierarchy process (AHP) method

Abstract Supiturang is one of the villages in Kecamatan Pronojiwo, Kabupaten Lumajang that sits on lahar flow path Semeru Volcano. The village constantly faces a lahar-flood hazard, inevitably impacting local community. Therefore, this paper aims to map hazard using analytical hierarchy process (AHP) method. main parameters are 1) slope (%), 2) distance from drainage (m), 3) elevation (m ASL), 4) rainfall (mm), and 5) land cover (water body/bare land/forest/grassland/plantation/ricefield/mixed agriculture/built-up area). This research descriptive-quantitative study used survey geographic information system (GIS) approaches. result showed class varies very low, moderate, high, high. high distributed near path. Despite most settlements being moderate class, some class. findings can advantage further improvement development evacuation routes, assembly points, refuges, observatory stations, other related Volcano disaster risk mitigation actions.
