Abstract
Sanitary condition is one of the components that influencing of public health. Bogor Regency has total area 2,663.81 km2, with total population 5,965,410 in 2019. The sanitation of Bogor Regency nearly 100% is using on-site systems. Utilization of septic tank reduce the level of contamination of surface water and groundwater. However, the sludge still contain high E.Coli that potentially caused diarrhea, vomiting desease, and others, so that the handling of the sludge needs Fecal Sludge Treatment Facilities (FSTF). Before 2016, The Bogor Regency already had 10 units of fecal suction truck services, but the disposal process still was done in Kalimulya FSTF, Depok City. So that, this study aims to find feasible FSTF site location which fulfill the spatial plan, technical, and non-technical criteria. The process on determining of feasible FSTF location was using multicriteria analysis using Geographic Information Systems (GIS). Several spatial data such as the land slope, the type of soil, distance from water bodies / river, the administration of Bogor Regency, as well as land use and land capability were used for FSTF site selection.
