Development Directives in Disaster-prone Areas based on Identification Level Vulnerability Using Geographical Information System Applications in Bogor Regency

Abstract

Bogor regency is one of the areas adjacent to the capital city of Indonesia, located at an altitude of between 15-2500 height mean sea level. The form of land in Bogor regency around 100-156 m shaped lowlands located in the northern part, about 100-500 m an undulating land located in the central part, mountainous area of 500-1000 m and Puncak area covering 2000 to 2500 m. The geographical position of Bogor regency, this area has led to disaster prone areas are large, among other disasters volcanoes, landslides, earthquakes, floods and erosion. Bogor regency most disaster-prone areas and is a protected area. Spatial direction of West Java province assign 45% of the area in Bogor Regency has a protective function as well as the National Strategic Urban Area is Jabodetabekpunjur area. Therefore require referral Bogor regency regional development in accordance with the conditions of the region, particularly in disaster-prone areas. Bogor Regency has a population density of 16.31 soul/km2 in 2010 and a population of 4759.329 soul in 266.383 km2 Bogor regency consisting of 40 districts. Bogor Regency developments led to an increasingly crowded housing needs and supporting facilities is increasing. Given the Bogor Regency is a disaster-prone area and most of the protected works, this research was conducted to provide recommendations on the direction of the development of disaster-prone areas that require development restrictions as one of the disaster relief effort. It is therefore necessary identification of areas - areas prone to superimpose maps pattern space, the ground motion hazard map, flood prone map, and seismic maps using Geographical Information System software (GIS.) GIS interpretation of the results shows that the area free of disasters and disaster-prone areas along its range. Once it is done compiling the results of interpretation of GIS with population density, so that the identified risk areas with limited development of the district which has a population density Ciomas 84.95 Soul / km2 with an area of 100% of disaster-prone areas. In this analysis, also conducted screening social characteristics and precedent studies to determine the direction of the proper development of the area restrictions in order to keep growing, especially Ciomas District in accordance with the potential and characteristics. Overall analysis of the results obtained on the development direction of the District of disaster-prone areas Ciomas based on the physical aspects, policy, social and related stakeholder.
