Design of leachate treatment in final disposal facility (TPA) Troketon, Klaten, Central Java
Troketon landfill is the only Waste Recycling Site owned by the Klaten government under DPU-PR with a capacity of 40.5 tons/day covering an area of 9.77464 hectares. This landfill has been operating since 2018 and has 3 landfill zone, 2 of them still under construction, while the other one is active...

| Summary: | Troketon landfill is the only Waste Recycling Site owned by the Klaten government under DPU-PR with a capacity of 40.5 tons/day covering an area of 9.77464 hectares. This landfill has been operating since 2018 and has 3 landfill zone, 2 of them still under construction, while the other one is actively using a controlled landfill collection system. Unfortunately, because it is new and emergency, this landfill does not yet have IPL. Based on field observations, the leachate produced will be allowed to collect at the lowest point of the landfill through waterways made from earth excavation, if rain arrives, the leachate will certainly overflow in all directions and cause environmental pollution. For this reason, it is necessary to design an IPL that serves to reduce environmental pollution due to leachate seepage in the Troketon landfill. The landfill zone of 2,3656 hectares is expected to produce leachate discharge of 180 m3 / day. Based on the results of the lab test analysis compared with LHK Regulation No. 59 of 2016, 5 of 7 parameters did not meet the quality standard with a concentration of pH = 7.3; BOD = 1640 mg / L; COD = 8000 mg / L; TSS = 340 mg / L; Total nitrogen = 3976 mg / L; cadmium = 0.001659 mg / L; and mercury <0.004 mg / L. Therefore, leachate treatment is needed in order to meet the specified quality standards. When viewed from leachate BOD / COD value of 0.201, it is included in the class of wastewater that is not biodegradable, but when viewed from the fraction of COD owned, the leachate is dissolved COD so that biological treatment can be applied. The alternative configuration was chosen using the SAW (Simple Additive Weighting) weighting method so that one of the configurations was chosen such as an equalizer, anaerobic contact tank, activated sludge, clarifier II, maturation pond, gravity thickener, and sludge drying bed. |
