Analysis of manganese (Mn) and copper (Cu) content in leachate water of Putri Cempo landfill, Surakarta

Abstract Leachate can contain hazardous components that can pollute the environment and health if not managed. This study aims to determine the content of heavy metals Mn and Cu in leachate from Putri Cempo Solo TPA and provide recommendations if the Mn and Cu values exceed the threshold. The method used is laboratory analysis. Analysis of Mn and Cu content was carried out using Atomic Absorption Spectroscopy by comparing the results of Mn and Cu content with quality standards according to PP 82/2001 Class IV concerning Water Quality Management and Water Pollution Control and PerMenKes 492/2010 concerning Mn content and PP 82/2001 Class IV concerning Water Quality Management and Water Pollution Control against Cu content. Laboratory test results showed that the Mn content was 33.7060 mg/l and Cu was 0.9294 mg/l. It is known that the maximum limit of heavy metal contamination Mn ranges from 0.1-0.4 mg/l and Cu is 0.2 mg/l. It was concluded that the heavy metal content of Putri Cempo landfill leachate has exceeded the quality standard. In order not to exceed the quality standard, it is recommended to treat leachate with coagulation-flocculation, adsorbent, and bioremediation processes.
