Abstract

Northern Jakarta coastal area is formed by some marine clay layers which has high compression as sedimentary soil. Land subsidence can occur due to several factors, such as load of building, excessive groundwater exploitation and normally consolidation process. Consolidation is a process of soil compacting due to the compression. The compression process of the soil occurs when soil receives the load from its above structure which makes a reduction of pore water pressure. Then, the dissipation of groundwater is followed by compaction of the volume of soil. A significant level of land subsidence in the coastal areas of Jakarta especially in Kamal Muara can lead to failure of building structures built on sedimentary clay soils. Therefore, research on the level of compression of sedimentary soils in the coastal areas of Jakarta needs to be done. This research is conducting by laboratory tests on UDS (undisturbed) soil samples taken by drilling a depth 50 meter point. The method used is the conso compression index lidation test for further analysis of the parameters of Pc, Cr, and OCR. Testing result shows the level of marine clay soil of coastal sediment clay in Kamal Muara North Jakarta is under consolidation. Keywords: compression index, pre-consolidation pressure, over consolidation ratio
