Landslide Vulnerability in Residential Areas for Disaster Mitigation in Sawangan District, Depok City

Abstract

Disaster occurs due to the interaction of threat factor, vulnerability and inability of the people. The lack of the capacity for decent settlement for the people has extended the use of lands for residential areas in unsuitable zone. Depok city is one of buffer zones of the capital city, Jakarta, with the population growth increasing significantly because of the pressure of the high human migration. The rapid development of an area becomes the trigger of the increasing need for lands. One of the destinations as settlement in Depok city is Sawangan district. Analyzing data technique that will be used is the descriptive analysis with the spatial approach. Map analyzing using the overlay analysis and classification. Based on the result of the overlay analysis from some maps, it shows that Sawangan district has the bumpy physical condition of an area with the slope rate of 3-8 %, population density rate of 4.001-6000 inhabitants per km2. But it has a potency leads to the land movement that is typically medium. It shows that there is a potency of human activity by building the residential-area with the high population density causes the landslide vulnerability tends to be high.
