PT. Kaltim Prima Coal Sangatta is a coal mining company that uses heavy equipment in Overburden removal activity. Heavy types of equipment use oil engines as engine lubricating fluid which is limited by its usage time, when the engine oil's useful life has been reached, the engine oil is drained and some of it is used as a mixture for explosives, a substitute for diesel fuel. This study will analyze historical data on the impact of blasting activities using used engine oil from heavy equipment, on operations and the environment using Response Surface Methodology, in the form of Ground Vibration. The result of historical data analysis that has been carried out using Response Surface Methodology, to obtain Ground vibration values that do not exceed 3,0 mm/sec, by maximizing the weight of explosive material by 907.46 Kilogram, then the percentage of explosives using used engine oil as a mixture of explosives is 43,98 %.

Keywords : Used engine oil, Response Surface Methodology, Ground Vibration.
