Determination Study of Landfill Location As A Potential Replacement For Bulusan Landfill Using Geographic Information System

Landfill is one of the important needs that must be provided and considered by a District. Nowadays, in Banyuwangi Regency already had one site of the landfill, but1.5 Ha site of this landfill could only accommodate wastes from 13 areas in Banyuwangi Regency. Bulusan landfill has currently exceeded the limit so it needed a new landfill. It was truly difficult to choose the new location for landfill if it had togo through a measurements field and check in every indicator session directly, so by using Geographic Information System (GIS) application, the selection of the location of landfill will be helped by using this system in terms of time, cost and energy with an effective and efficient process, and an optimal results. This research aimed to determine the candidate of location replacement of the Bulusan landfill that appropriate to Indonesia's National Standards (SNI) No. 19-3241-1994 with Geographic Information System (GIS) help. The process of determining landfill candidate used a scoring method by using Geographic Information System (GIS) to search certain areas that decent to be the location of the landfill. The selection of landfill area consisted of 3 stages namely regional stage, allowance stage, and determination stage. In the regional stage, there were 10 candidates as the recommended location with the highest overlay score. Then, it continued to the allowance stage. In this stage, the highest score of 10 recommended locations would be chosen. The final stage was the determination stage, which was one of the new landfill location decided. As the result, the appropriate recommendation for the replacement candidate of Bulusan landfill was Location Candidate number VII which was located in Ketapang Village, Kalipuro sub-regency with area 0.4641 km
