Timbulan sampah di Indonesia terus meningkat mencapai 64 juta ton/tahun pada tahun 2015. Sebesar 69% dari sampah tersebut diangkut dan ditimbun di Tempat Pemrosesan Akhir (TPA), menunjukkan paradigma “Kumpul-Angkut-Buang” yang masih diterapkan pada pengelolaan sampah masyarakat Indonesia. Upaya daur ulang telah diketahui menjadi cara yang cukup efektif untuk mengurangi beban timbulan sampah di TPA. Namun, pada kenyataannya masih ditemukan sampah di TPA yang masih berpotensi untuk didaur ulang. Material Recovery Facility (MRF) merupakan fasilitas pengelolaan sampah yang bertujuan untuk mengolah sampah dan memanfaatkannya kembali dengan serta mereduksi jumlah sampah yang dihasilkan. Perancangan yang dilakukan yaitu berupa perancangan tipikal desain MRF dengan kapasitas 50 ton/hari pada lokasi studi lahan bekas TPA Leuwigajah. Sampah input yang digunakan yaitu sampah domestik rumah tangga khususnya sampah anorganik dengan komposisi 48,27%. Alternatif MRF terpilih terdiri dari pengolahan mekanis awal berupa bag opening, teknologi pemisahan berupa penyaringan menggunakan trommel screen, pemindahan material menggunakan conveyor belt tipe flat dan incline conveyor tipe crossbars, pemilahan manual, magnetic separator menggunakan pulley magnetic, serta eddy current separator. Pengolahan mekanis size reduction menggunakan shear shredder, pengolahan mekanis akhir berupa kompaksi menggunakan horizontal baler, dan fasilitas kantor, tempat parkir, pos satpam, drainase, serta akses jalan yang dilengkapi dengan jembatan timbang. Total luas tipikal MRF sebesar 0,574 Ha. Proses di MRF menghasilkan material daur ulang yang telah terpilah dengan total sampah yang di recovery sebesar 36,329 ton/hari, total residu sebesar 13,671 ton/hari, recovery system sebesar 93,41%, kemurnian material recovery sebesar 100%, serta efisiensi sistem sebesar 93,41%.

Deskripsi Alternatif :

The waste generation in Indonesia has increased, reaching 64 million ton/year in 2015 and 69% of the waste just dumped into direct landfill. The figures showed that Indonesian people still “Collect-Transport-Disposed” their waste. Recycling efforts have been known to be a fairly effective way to reduce waste discharge on landfill. However, it is in fact still found waste in landfill is still potentially to be recycled. Material Recovery Facility (MRF) is a waste management facility that aims to cultivate the waste and put it back with the aim of reducing the amount of waste generated. The design is a typical design of MRF with the capacity of 50 ton/day in Leuwigajah landfill. The waste input will be from household domestic waste especially inorganic waste with the composition is 48.27%. The chosen alternative of MRF consist of pre-mechanical treatment for bag opening, separation technology for screening using a trommel screen, moving conveyor belt using material type flat and incline conveyor type crossbars, manual sorting, magnetic separator using magnetic pulley, and eddy current separator. Mechanical size reduction using shear shredder, compaction process using horizontal baler, and additional facilities such as office, workshop, parking, post security, drainage, as well as the access roads that are equipped with weighbridge. Total area of MRF is 0.574 Ha. MRF process produces recycled materials that have been disaggregated by total waste on recovery of 36.329 tons/day, total residues of 13.671 tons/day, recovery system is 93.41%, purity of the material recovery is 100%, and efficiency of the system of 93.41%.
