Model Fisik Kincir Air Untuk Irigasi Pertanian Analisis Daerah Rawan Longsor Berbasis Sistem Informasi Geografis (Studi Kasus : Kabupaten Lima Puluh Kota, Sumatera Barat)
Lima Puluh Kota is one of the regency in West Sumatera Province that prone to landslide, particularly when the rainfall intensity is high. The research is conducted to determine the area that prone to landslide in Lima Puluh Kota regency in order to prevent the risk that potentially leads to disaster. The method applied to determine the prone landslide areas is Indeks Storie method, which would be treated in Geographic Information System’s program. Overlay process performed on parameters related such as slope, soil types, precipitation, and landuse, then marked the score in each of criteria from the parameters map. Based on the level classification analysis by Arifin S, et al (2006) Lima Puluh Kota regency is on the very low, low, and medium levels of landslide prone. This condition is contradicting with the actual fact. Based on level classification analysis by Nugroho, J.A, et al (2009) there are areas in Lima Puluh Kota that have very low, low, medium, high, very high levels of landslide prone which close to the actual fact.
