T The coastal area of north jakarta is a region with a high level of vulnerability toliquefaction phenomena due to the dominance of saturated sandy soil layers andshallow groundwater levels. this study aims to identify the depth of soil layers thatare potentially susceptible to liquefaction. the research method involves theanalysis of subsurface soil data obtained from 26 borehole points distributed acrossthe ancol, pluit, tegal alur–pantai indah kapuk (pik), and cilincing areas. theevaluation of liquefaction potential is conducted based on geotechnical soilparameters, particularly n-spt values, soil type, degree of saturation, andgroundwater level. the results indicate that the ancol and cilincing areas exhibitthe highest level of vulnerability, characterized by more extensive and evenlydistributed liquefaction-prone depths compared to other areas. meanwhile, thepluit and tegal alur–pik areas show relatively more limited liquefaction potential;however, these areas still require attention due to the presence of dense residentialsettlements located above susceptible soil layers. the estimated economic loss toresidential buildings caused by liquefaction in the study area reachesapproximately rp4.73 trillion, with per capita losses ranging from rp3.46 millionto rp6.34 million per person. the highest relative losses occur in areas with higherproperty values and greater levels of building damage. the findings of this studyare expected to serve as a consideration for disaster risk mitigation planning,particularly related to liquefaction hazards, as well as a basis for policymaking andsustainable development management in the coastal area of north jakarta
