    The grounding system plays an important role in the electrical system part as it gives protection during fault or lightning occur. The main purpose of the grounding system is to protect humans, electrical appliances and buildings from electrical shock due to lightning or another form of electricity that hazardous. Thus, to install an excellent electrical system and complete its circuit, a grounding system performance must be taken into account. But, in certain cases, due to the geological condition, the soil resistivity is not good enough. Therefore, enhancement filler material has been used to reduce grounding resistance. In this project, it is aimed to elaborate on the usage of Coconut Husk, Paddy Husk, and Bentonite as grounding filler materials to reduce the soil resistivity and improves the grounding system. The result showed that Bentonite showed better performance compared to Coconut Husk and Paddy Husk.

    Natural enhancement material often uses to improve performance of the soil resistivity in grounding system. Due to the different soil condition, focus for effective grounding go to the soil itself. Soil resistivity, moisture content and surrounding environment contribute to the impedance of the grounding. The usage of material to enhance the grounding can be considering important to maintain the grounding system performance. There are several techniques used to treat the soil using chemical substance known as grounding enhancement material. This technique produces low resistivity to the grounding electrode however the soil become contaminated. This paper will discuss about the performance of coconut husk ashes and bentonite as natural enhancement material and method being used to evaluate the results.
