【 摘 要 】

Grounding resistance of the earthing system is affected by soil resistivity. Soil resistivity should have a high-water content (moisture) inside the ground. Soil moisture can be made and maintained by substance addictive that can absorb water in vicinity. This research uses bentonite as an additive. It has undergone the heating process in different temperature and duration before used, thenbentonite is mixed into the soil with the different composition. Those treatments are categorized as physics-activated. The aim of this research is to analyze the effect of bentonite in order to reduce soil resistance. The grounding resistance is observed with and without bentonite. The earthing system with bentonite as addictive has the smaller grounding resistance than that without bentonite. The biggest percentage of reduction in grounding resistance are 74% due to bentonite which is activated at temperature 2000C. Non-activated bentonite can achieve 68% reduction in grounding resistance. In contrast, the composition of 50% non-activated bentonite and 25% soil can reduce the grounding resistance by 69%.
