Abstract

The population in Semarang City is increasing in number. The limited area of settlements has caused many settlements to be established in unfavorable locations, which are located in landslide prone areas. The purpose of this study is (1) Determine the distribution of settlement environments prone to landslides with the help of GIS (Geographic Information System) technology in the Ngaliyan District of Semarang City, (2) Analyze community efforts in tackling settlements that are prone to landslides.The variables studied were: (a) terrain physical including: slope, soil texture, density (number) incision, land use, rock weathering depth, steep walls, soil solum, soil permeability, vegetation density, rock weathering, structure rock lining, rock strength, groundwater depth, concentration of springs / seepage, and rainfall; (b) Land use for settlements. Data was collected through field surveys. Data analysis with scoring, and overlaying with GIS technology. The total score is used to determine the distribution of landslide prone areas. Landslide hazard maps are then overlay with residential land use maps with the ArcGIS program, so that maps of residential areas prone to landslides can be obtained.
