T he northern part of DKI Jakarta is composed of alluvial deposits of quarter age (Turkandi et al., 1992). The rocks in these deposits have soft physical characteristics because they have not been completely consolidated. Taman Sari District is administratively included in the City of West Jakarta but geographically is located in the north. Population growth and urbanization activities have the potential to cause disasters, one of which is land subsidence. Analysis of the influence of building loading and soft rock bearing capacity was carried out based on sondir and N – SPT data. Observation of the land cover of the research area was carried out by observing satellite imagery and direct observation in the field within 15 location. Calculation of the estimated building load using the equivalent truss method. Based on the analysis carried out, the carrying capacity of 5 m depth has the lowest value of 3.1 tons/pile and the highest value of 22.7 tons/pole. At a depth of 10 m the lowest value of carrying capacity is 16 tons/pole and the highest value is 64 tons/pole. Buildings with a 5 m depth pile foundation in the study area have the potential to cause soil subsidence because the load is greater than the rock's bearing capacity. Meanwhile, buildings with 10 m deep piles in the study area do not fully have the potential to cause land subsidence.
