IDENTIFICATION OF RECLAMATION AREA IN ANCOL OF NORTH JAKARTA USING IMAGING RESISTIVITY

The coastal reclamation area is the result of the expansion of the coastal area through technical engineering for the development of new areas. Identification of the reclamation area can be done by detecting subsurface imaging using the resistivity method. This study using the resistivity imaging method using multi electrodes (multichannel). The results of this resistivity imaging were obtained underground imaging that showed a good response. With showing a small resistivity value <27.8 Ωm which was identified as an almost total reclamation area within the study area. Depth varying from 4 meters to 30 meters. The reclamation results are composed by loose rocks that have not been fully compacted, so that they have not been properly consolidated. The consequently if they are overloaded they will experience subsidence.
