Spatial model of land subsidence mitigation at lowland areas

South Sumatera is one of the provinces with a large number lowlands in Indonesia consisting tidal land and lowland swamps, which located Tanjung Api-Api. The conversion into built-up areas will cause physical, socio-economic, environmental, public health impacts. One impacts arising from development settlements infrastructure subsidence flooding. purpose this research to create model for mitigating spatially. spatial carried out by weighting Analytical Hierarchy Processes (AHP) then mapping mitigation efforts that be based on potential subsidence. results show if area developed an industrial residential area, it have impact moderate high level. Based zoning subsidence, best pre-disaster do are choosing type construction according soil, conserving groundwater, maintaining infiltration green open spaces, regional planning.
