Accumulation of Copper (Cu) and Cadmium (Cd) Ions in Settling Basins to Assess the Effectiveness of the IPLT TPA Putri Cempo, Surakarta

Abstract Decreased water quality is caused by various human activities. One of the most dangerous types of water pollution is heavy metal pollution. Exposure to heavy metals can endanger human health even at low concentrations. One source of heavy metal pollution comes from domestic waste pollution from domestic activities, fecal waste. Fecal sludge contains solids dissolved in water, in the form of a mixture of organic materials and heavy metals, making it hazardous if not treated first before disposal. In this research, the author used water samples from the IPLT TPA Putri Cempo to determine the levels of Copper (Cu) and Cadmium (Cd) and the hazards posed by heavy metals, in order to assess the effectiveness of the Putri Cempo TPA IPLT system. The method used was wastewater sampling from the Putri Cempo landfill final sedimentation tank, sample preparation and analysis with atomic absorption spectrophotometer (AAS). The results of the investigation show that the final pool water at Putri Cempo landfill contains 0.0155 mg/L of copper and -0.0076 mg/L of cadmium, where these results are still below the threshold set by wastewater quality standards in Indonesia.
