The sophisticated Geoelectrical instrument owned by consultant Prihaditama with the ARES II from Czech Republic participated in helping the PLP Team and Drinking Water DPUTR Gresik Regency in
finding water sources in Banyuurip Village, Kedamean District and Karangandong Village, Driyorejo District on Friday, April 30, 2021.
This geoelectric tool is an instrument that can inject a maximum of 500 watts of an electric current into the earth through a pair of electrodes. Electrodes made of stainless steel are connected with a single cable and the tool
is through an automatic scanner box. Automatic box scanners have complex circuits that can accommodate as many as 48 electrode cable lines. At the same time an electric current is flowing into the earth, another pair of
electrodes acts as a measure of the voltage difference arising from the injection of the electric current. The special algorithm for the geoelectric device is capable of making 24 pairs of electrodes (48 channels) act as
current injections and as a measure of the difference in electric voltage. The material below the earth's surface contains minerals or fluids in rocks that have electrical properties, namely continuing or conducting electric
currents or inhibiting electric currents. Materials that can easily conduct electric current are called conductors and are conductive, while materials that are difficult to conduct electric current have resistive properties.
The physical property of the rock, known as resistivity, is calculated by involving the injected
electric current, the measured voltage difference, and the distance between the 2 pairs of electrodes. Some geoelectric measurement techniques can be read further in this article. The results of geoelectrical measurements in
the form of resistivity are then continued to the modeling stage.
The presentation of geoelectrical model results can be more easily interpreted by an experienced geophysicist and also discussed further with related geologists.
