Bandung is the capital of West Java, which has a population in each region, one of the regions is Rancaekek. Population density must have sufficient water needs for daily needs. However, excessive use of water and must be carried out by taking ground water continuously without control will cause soil settlement or land subsidence which will have a major impact. In addition to these factors, there are some who report land subsidence such as decreases due to building loads, decreases due to an increase in the number of layers of soil, and a decrease due to tectonic forces. Land subsidence is land subsidence from changes that occur underground. This study proves the reversal of land subsidence in Rancaekek which causes cone subsidence. Cone subsidence is formed by a basin from the surface of the earth and causes a difference in height with the surrounding area. The results of proving the existence of a sinking cone will be a consideration of the abundance of flooding in Rancaekek with the presence of a river near the area. The methodology used is the study of literature and direct data collection to the Rancaekek area using multi GNSS RTK technology.
