Abstract

Abstract: Jetak Sub-Village, Getasan Sub-District, Semarang Regency, was an area that had found difficulty in getting clean water because it was not located in the groundwater basin area. The correlation between the Horizontal to Vertical Spectral Ratio (HVSR) and the Resistivity method could be used to determine the estimation of the aquifer's presence. Based on the interpretation of the correlation results of the HVSR model using the Vp/Vs ratio against the rock resistivity value showed the presence of shallow aquifers at a depth of between 20-50 m below the earth's surface in the sandstone layer. Sandstone based on HVSR at a location that has a Vp/Vs ratio of 1.8-2.3 and in resistivity modeling had a value of 21.1ohm-m. These results indicated that the aquifer is not a groundwater aquifer that can be used for needs during the dry season.
