Composition of mixing gypsum additives as environmentally friendly material in tropical soil to reduce grounding resistance

Abstract

Grounding resistance is directly proportional to the amount of soil type resistance. While soil type resistance is influenced by several things, namely soil structure, temperature, the effect of water content (moisture), and the effect of chemical content in the soil. The purpose of this study was to analyze the decrease in the value of earth resistance by adding additives in the form of gypsum without a mixture of soil and gypsum mixed with soil. The results showed that the value of grounding resistance with the addition of gypsum without soil mixtures had a higher resistance value than grounding resistance without the addition of additives. Grounding resistance with the addition of gypsum mixed with soil on average can reduce the value of grounding resistance by 153.56 ohms with 25% gypsum, 157.2 ohms with 75% gypsum and 169.91 ohms with 50% gypsum.
