Piyungan Regional Landfill serves the city of Yogyakarta, Bantul and Sleman operated with open dumping system, the landfill area is about 12.5 hectares, operated since 1996 and the amount of garbage that goes around 400-500 tonnes per day. In 2016 the amount of waste reach 550.458 tonnes / day, and predicted the next 10 years the number will reach 663.375 tons / day, and at 20 years will be 676.047 tons / day. One of many problems facing by the current landfill management is the Leachate Processing Unit. Total population of TPA Piyungan service area in 2016 reached 2,581,750 people. TPA Piyungan was predicted able to manage waste from DIY until the year of 2026. The increasement of the population affects to the increasement garbage dump enters into landfill. Will be conducted the analysis if Recycle effort will be done in 2027-2036 before garbage enter to landfill in term to extend landfill’s lifespan up to 20 years. Required optimization of leachate processing unit at Piyungan landfill considering to the leachate quality of existing unit still does not meet quality standards in accordance to Governor Regulation No.07 DIY 2010 (Peraturan Gubernur DIY No. 07 tahun 2010) about Industrial Wastewater Effluent. The Increasement of population growth and landfill management system operated at TPA Piyungan brings problem in the overloading of garbage dump at landfill and influence the higher leachate production. The leachate treatment units are less regularly maintained make the quality of leachate at the outlet still doesn't meet the standard regulation. <br /> <br /> <br /> Will be done the analysis to redesign the leachate treatment installation unit by using three alternatives, those are; chemical-physical alternative, biological alternative, and chemical-biological alternative. From each alternative then will be calculated which is the best efficiently used technically and low cost economically to operate. From the calculation then conclude if biological treatment by using Activated Sludge is the best alternative to be applied in this case. Parameter will be focused on this scope of design will be Total Suspended Solid (TSS), Ammoniak, Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD).
