Abstract
Surface porosity conditions in part of flood-prone areas at Rawa Makmur Village have been mapped from the surface to a depth of 30 meters. The aims of this research are to identify the infiltration of soil which is described by variations in resistivity and rock porosity values. It is obtained from the 1D geoelectric method using Vertical Electrical Sounding and as many as 10 measurement points. According to analysis, it is explained that Rawa Makmur area has low porosity and resistivity values. The porosity conditions in the observation point area were in very bad conditions. The infiltration process is very slow, causing the accumulation of a large amount of water mass and a fairly high pool of water. It also showed that the water flowing in this area was difficult to infiltrate, so it caused the Rawa Makmur area to become flooded when it rained.
