Abstract

Design of geoelectric resistivity measurement system using a constant current source has been successfully created and analyzed. Geoelectric resistivity measurement system consists of a boost converter circuit, constant current source, and a microcontroller as the control system in the process of measurement and data acquisition resistivity geoelectric form of resistance data. Data acquisition system using the principles of Ohm’s law, the geoelectric method of Wenner. In this study, a constant current source that is successfully implemented on geoelectric resistivity that is a current of 0,1 mA work on resistance 0,4  until 2,345 M and a current of 1mA is working on 0,4  resistance to 8,53 k. As well as the resistance measurement can be measured by either the resistance measurement 33 to 470 k.
