Identification resistivity value of soil: Alternative substitute resistance material on resistor

Abstract

This study utilized soil as a raw material for making resistor. The type of soil use is latosol soil, organosol soil, and clay. The method used is an experiment. These soils are very densely compressed into a tube with a surface area (A) = 6.3 × 10-4 m2. Each of the tube have a length (l) = 1.5 × 10-2 m and diameter (d) = 1 × 10-2 m. The results of resistance value can be observed through measurement using a multi-meter on the artificial resistor. Found the resistance value from latosol soil, organosol soil, and clay in a row is at 66.3 kΩ; 58.6 kΩ; 47.1 kΩ. The results are used to determine the value of resistivity through a formula. The results showed that latosol soil, organosol soil, and clay respectively have a value of resistivity of 2.78 kΩm; 2.46 kΩm; 1.98 kΩm. This study shows that soil can be used as an alternative to resistance on the resistor material. These results also indicate that resistivity value of latosol soil higher than organosol soil and clay.
