Detailed mapping for the conservation of karst area in the limestone prospect area in Bojongmanik, Lebak regency, west Java province, Indonesia

Conservation of karst area is necessary amid the rampant exploitation that occurs. The area of Bojongmanik in Lebak Regency, West Java Province has potential limestone content. Detailed mapping of the karst phenomenon is important to reduce the negative impact of exploitation of this area. The results of this study recommend 4 karst areas that are feasible to be conserved and 5 blocks of limestone mining prospect areas. One of the conservation areas is the Cimuli Karst Conservation Area, which is located in the west of the exploration area and occupies an area of around 9.23 hectares.
