As Jakarta's buffer zone, the mobilization inhibition of Bekasi people will impact economic activities in Jakarta. Therefore, a mitigation measure is needed to reduce losses. This research aims to map the flood exposure of Bekasi's settlement areas as a reference for mitigation action. The level of exposure in this research is analyzed by assessing rainfall, land use, slope, altitude, drainage conditions, and distance from rivers. This exposure mapping uses remote sensing data based on Geographic Information Systems (GIS).
