Identification of aquifer zone in the southern part of Sukoharjo Regency using VES method as a means of irrigation of agricultural land

Abstract

Sukoharjo is one of the regencies in Indonesia that is famous for its agricultural land. Sukoharjo itself has 12 sub districts spread evenly throughout. In recent years, there have been many conflicts of irrigation water shortages for agricultural land. Therefore, research was conducted on the aquifer zone of the southern district of Sukoharjo. The research was conducted by Vertical Electrical Sounding method to determine the structure of soil in order to improve the efficiency of deep groundwater drilling for irrigation. The study used Schlumberger’s configuration with a target zone of deep aquifers for agricultural irrigation. The length of the track used is 275-300 meters. As a result of the study, it is suspected that the aquifer zone in southern Sukoharjo Regency has a depth of about 11.54-83.93 meters below the subsurface. The soil structure in south of Sukoharjo is dominated by sandy clay layers, limestone layers, and sedimentary layers.
