Based on the results of the analysis with this method, it was found that the result of the elastic decrease was 0.212 m. with the thickness of the pile needed was 6 meters to reach the target elevation.therefore PVD planning, with a triangular configuration with the distance between PVD needed is 1.4 meters with a radius of PVD 0.74 meters and a depth of 17 meters. In this planning has a target land can be consolidated with PVD for 90 days.PVD planning requires a budget of Rp.15,137,203,180. these costs include PVD work (Prefabricated Vertical Drain), PHD job(Prefabricated Horizontal Drain,Quality Control and Landfill with Urug Land.
