Abstract:
The aim of the research was to determine the quality of leachate water in the processing unit (IPAL) of TPA Sowi Gunung and the quality of surface water around the TPA in relation to the operation of the IPAL TPA.The method used in this research was descriptive method with cross sectional survey technique by collecting leachate samples from the IPAL unit and surface water samples from two springs around the landfill area.It was accompanied by in-situ measurements of pH parameters and continued with 6 parameter quality analysis others (TSS, TDS, BOD, COD, N-total, TOC) at the Laboratory of the Research Center for Environmental Assessment, University of Papua. The result of the research was known that the parameters of pH, TSS, BOD, COD, N-total, and TOC in the TPA IPAL unit were categorized as under quality standards (PerMenLHK No.59 of 2016).In particular, the TDS parameter does not have a tolerance limit corresponding to this quality standard so it becomes a separate consideration in its management considering that water with a high amount of dissolved solids> 1000 mg / L that has an unpleasant taste, so it is not suitable for consumption. Likewise, the quality of surface water at 2 (two) observation points of springs through parameters of pH, TSS, TDS, BOD, COD, N-total, and TOC were categorized as under class I water quality standards according to PP No. 82 of 2001 concerning water quality management and water pollution control
