Abstract

The number of residents in Bandung continues to increase every year, especially in the southern part of Bandung. The development of residential areas needs to get attention from the local government and people in Bandung, especially to evaluate various geological hazards such as floods, landslide, earthquake, and other. Research methodolgy is qualitative method by interviewing local community and analyzing landsat image using Google Earth and Digital Earth Model (DEM) image to know land use in the research area. In addition, quantitative methods are also used with superimposed manual statistical analysis and weighting methods using Microsoft Excel, Global Mapper, and Mapinfo software. The result of research shows that South Bandung area has Land Suitability Score > 130 (Residential Area) and Land Suitability Score > 135 (Agriculture Area) which are categorized as very good settlement and education area; Land Suitability Score 116-130 (Residential Area) and Land Suitability Score 92-135 (Agriculture Area) are categorized as an obstacle area with various constraints such as water supply, disaster, and others but can still be overcome by artificial engineering. Land Suitability Score <116 (Residential Areas) and Land Suitability Score <92 (Agricultural Area) are limitation area that are not feasible to be used as residential and educational areas, a variety of constraint reduction efforts can be done but require very high cost. Therefore it is suggested  to convert the area into conservation. It is concluded that the best areas to be used as residential and agricultural areas are located in the Banjaran District such as Banjaran, Kamasan, Sindangpanon, and Tarajusari Village.

Abstract

The flood can affect an area so cause great loss. Muaragembong is one of the sub-districts in Bekasi Regency. This area is known as an area that is regularly hit by floods. The purpose of this study is to analyze changes in flood areas, specifically those related to residential areas. The results showed significant changes in the flood area from 1993 to 2016. Increased changes in land use from swampy areas and mangrove forests to residential areas are thought to be the cause of the increase in flooding every year. One way to reduce the impact of flooding in Muaragembong is to restore the existence of mangrove forests along the Citarum River to the sea.Keywords: Flood, Muara Gembong, Citarum River, Land Use
