Abstract :
Earth resistivity measurements have been carried out using a rock
electrical resistance determination tool using the Arduino Uno based Wenner
configuration geoelectric method, this study aims to determine the underground
structure around the Bengkalis State Polytechnic. This research was conducted
using the Arduino Uno-based Wenner configuration geoelectric method.
Measurements were made for 4 days, the first day, the stretch of cable was varied
and the average rock type produced was quartz, andesite, rock salt, granite,
limestone, sandstone, dry gravel. On the second day AB measurements were made
constant, which is 30 meters and the average rock type obtained was, quartz ,
rock salt, granite, limestone, sandstone, shales, dry gravel, andesite. On the third
day the AB stretch measurements were made constant, ie 90 meters and the
average rock type obtained including, quartz, rock salt, granite, limestone,
sandstone, dry gravel, andesite. On the third day AB measurements were made
constant, ie 210 meters and the average rock type obtained including, quartz, rock
salt, granite, andesite. In general, quartz rock, rock salt, granite, andesite are
always obtained in every measurement.
