Enhance Utilization of Bentonite, Lime and Waste Buildings to Increase the Land Capacity Tropical

Tropical soils are generally dominated by clay minerals which have a capacity Cation exchange (CEC) and low electric charges resulting in sortition capacity low to soil electrolytes (especially ground water). Flow ability the electron charge that comes from a lightning strike becomes low and resistant soil type becomes high. This has an impact on the ability to flow through the load electrons from lightning strikes become low. For this reason treatment is needed of land that will be used as a grounding media in a way addition of additives. This study uses grounding media between soil mixtures (T) with debris (P), soil with bentonite (B), and soil with lime (K). Each mixture (T: P), (T: B), (T: K), made with a concentration of 25:75, 50:50, 75:25 and 100% land as a control. Distance between electrode implements between 1 meter treatment group, and different ground dimensions. The measurement method used is a three-point method with using a single ground rod electrode. The results showed the best response to decline successive resistance is in the soil mixture with debris, then followed by soil with lime and soil with bentonite. Water content effect on decreasing soil resistance. The greater the water content
