Abstract

The land subsidence risk map of Bandung and Cimahi city has been constructed by the combination of sevens availabole data then grounp into three gorupes such as land subsidence hazard , vulnerability and caapacity of prevention and reduction with Analytical Hierachy Process (AHP) method and Geographic information system (GIS) . Hazard risk analysis of land subsience is so complecated issue aiming at identifying the zone of very high, high, moderate, low and very low, account for 4.26%, 15.92%, 12.15%, 18.60% and 49.07% respectively of the total research area 208.95301km2. The very high risk of land subsidence region is the area of the very high vulnerability, high hazard and low capacity of prevention as in south Cimahi district then, southern district of Bandung City such as Bandung Kulon, Bandung Kidul, BabakanCiparay, Bojong Loa Kidul, Rankasari, and South Cimahi district etc. as high risk regions and moderate risk regions represent in the central of study area such as, central Cimahi, Kiaracondong, Lengkong, Batununggal. In contrast, mostly, the very low risk of land subsidence regions were indicated in the the area of low potential of land subsidence, very low in vulnerability and high capacity of prevention and reduction as at the northern part of research area.

Keywords: Land subsidence risk map, Analytic Hierarchy Process (AHP), Geographic Information System (GIS)
