PEMETAAN POTENSI BAHAYA LONGSOR DI DAS MANIKIN DENGAN MENGGUNAKAN ANALISIS SISTEM INFORMASI GEOGRAFIS

Abstract

ABSTRAK This research was conducted in order to understand the potential of landslide hazards in the Manikin Watershed and to map the slide hazards so that it can be used as a reference in conducting landslide disaster mitigation. The method used was scoring which was based on the Regulation of Minister of Public Works Number 22 /PRT/M/2007 about Guidelines for Spatial Planning for Landslide Disaster Prone Areas, and the parameter used were soil type, geological formation, rainfall, land use and slopes. The results of the research showed that the landslide potential in the Manikin Watershed is dominated by Low Landslide Class which is 6,924.703 Ha in area or 54.912 %. The next is Medium Landslide Class which covering an area of 3,881.911 Ha or 30.783%, the High Landslide Class covering an area of 1,758.058 Ha or 13.941%, and the Very High Landslide Class covering an area of 45.96 Ha or 0.364%.
