Safe and proper disposal of waste is an important component in integrated waste management. The method of accumulating garbage in landfills (TPA) can result in a decrease in environmental quality due to air pollution due to solid waste burning, groundwater pollution due to leaching, and an increasing number of disease vectors that can endanger the health of waste collectors and residents. around the landfill. The purpose of this study was to determine the metal content of Lead (Pb), Mercury (Hg) and Copper (Cu) in the leachate of TPA BatuBola. This research method uses descriptive exploratory method by conducting a survey first. Atomic Absorption Spectrophotometer is a tool used in this study. Data analysis was carried out by comparing the test result data with the quality standards by Permen LHK P.59 / 2016 and Permen LHK No.5 / 2014. The data shows that the concentration of Hg metal is <0.0004 mg / L. Meanwhile, the threshold set by the government is 0.005 mg / L. The concentration of lead metal (Pb) also shows a value that is below the quality standard threshold, namely <0.003 mg / L, while the set limit is 0.1 mg / L. As well, the measurement of copper metal (Cu) is still below the quality standard threshold, namely <0.006 mg / L, while the limit set by the government is 2.0 mg / L. However, caution must be exercised because if it is accumulated in large quantities it can still be dangerous.
