<![CDATA[Abstrak:Kebakaran yang terjadi pada Tempat Pemrosesan Akhir (TPA) Cinangsi pada tahun 2015 menyebabkan TPA Nangkaleah di Kec. Wangunreja, Kab. Tasikmalaya harus dioperasikan lebih cepat, walau pun TPA Nangkaleah belum dilengkapi beberapa fasilitas pengolahan akhir, di antaranya adalah unit pengolahan lindi. Desain awal unit pengolahan lindi TPA Nangkaleah dinilai jauh lebih kecil daripada total timbulan lindi dari sampah yang didatangkan dari area pelayanan TPA Cinangsi dan rencana area pelayanan TPA Nangkaleah. Dengan demikian diperlukan desain fasilitas pengolahan lindi yang memiliki kapasitas jauh lebiih besar. Tujuan penelitian ini adalah untuk merencanakan desain unit pengolahan lindi berdasarkan proyeksi timbulan sampah dari 2 (dua) area pelayanan, data curah hujan dan proyeksi timbulan lindi. Hasil penelitian ini menunjukkan bahwa proyeksi debit timbulan lindi adalah sebesar 0,94 m3/hari. Fasilitas pengolahan lindi yang direncanakan terdiri dari 2 (dua) unit kolam penampungan lindi dengan kapasitas masing – masing kolam sebesar 30 m3, kolam stabilisasi dengan kapasitas 20 m3, kolam aerasi dengan kapasitas 20 m3, kolam maturasi dengan kapasitas 15 m3, sistem resirkulasi lindi dan lahan basah (wetland). Fasilitas tersebut dinilai mampu menurunkan kadar pencemar lindi hingga memenuhi baku mutu lingkungan.Kata Kunci: Tempat Pembuangan Akhir Sampah, lindi, fasilitas pengolahan lindi, kadar pencemar, baku mutu lingkungan.Abstract: A fire disaster that occurred at the Cinangsi sanitary landfill in 2015 leads the Nangkaleah sanitary landfill in Wangunreja, Tasikmalaya must be operated earlier, even though the Nangkaleah landfill has not been equipped with several final processing facilities, including a leachate processing unit. The initial design of the leachate treatment unit at the Nangkaleah landfill is considered to be much smaller than the total leachate generation from waste imported from the Cinangsi's service area and the planned Nangkaleah's landfill service area. Thus, it is necessary to design a leachate treatment facility that has a much larger capacity. The purpose of this study is to plan the design of leachate treatment units based on projections of waste generation from 2 (two) service areas, rainfall data, and projections of leachate generation. The results of this study indicate that the projected discharge of leachate at Nangkaleah landfill is 0.94 m3/day. The leachate processing facility that is planned consists of 2 (two) units of leachate storage ponds with a capacity of 40 m3 each, a stabilization pool with a capacity of 20 m3, an aeration pool with a capacity of 20 m3, a maturation pool with a capacity of 15 m3, a leachate recirculation system and wetland area. The facility is considered capable of reducing levels of leachate pollutants to meet environmental quality standardsKeywords: Landfill, leachate, leachate treatment facility, pollutant levels, environmental quality standards.]]>
