Salah satu permasalahan yang dihadapi PT.X sebagai perusahaan yang terus berkembang adalah permasalahan dalam pengelolaan sampah. Meskipun sudah ada mekanisme pengelolaan sampah seperti pemilahan dan pewadahan tetapi belum sepenuhnya terlaksana dengan baik. Salah satu upaya yang dilakukan adalah dengan merencanakan fasilitas pengelolaan sampah yaitu Material Recovery Facility (MRF). Konsep MRF; SOP dalam operasional MRF; potensi ekonomi sampah; dab analisa gas rumah kaca (GRK) di PT.X Penentuan karakteristik, komposisi dan berat sampah dilakukan dengan menggunakan wadah plastik dan penimbangan selama 8 hari mengacu pada SNI 19-3964-1994 dan SNI 19-2454-2002. Perencanaan komponen MRF dibuat berdasarkan perhitungan karakteristik, komposisi, dan berat sampah. Standar Operasional Prosedur (SOP) dibuat berdasarkan kegiatan operasional yang ada dalam MRF. Analisa gas rumah kaca mengacu pada buku Tchobanoglous dkk, 1993. Hasil penelitian yang dilakukan selama 8 hari berat sampah organik di PT.X adalah 119,83 kg sedangkan untuk berat sampah anorganiknya adalah sebesar 241,64 kg. Densitas sampah sebesar 612,52 kg/m3. Laju timbulan sampah karyawan tahun 2015 sebesar 0,1646 kg/orang/hari sedangkan laju timbulan sampah kontainer tahun 2015 sebesar 0,0034 kg/kontainer/hari. Proyeksi pertambahan jumlah karyawan dan kontainer pada tahun perencanaan (2020) sebanyak 70 orang dan 15.962 unit kontainer menghasilkan laju timbulan sampah yang dihasilkan oleh karyawan sebanyak 11,232 kg/orang/hari dan laju timbulan sampah yang dihasilkan oleh sampah kontainer sebanyak 15,17 kg/kontainer/hari. Prosedur pemilahan sampah kering dan basah, prosedur penyimpanan barang sortir, prosedur penampungan sampah organik, prosedur proses komposting, dan prosedur penyimpanan produk kompos. Total nilai ekonomis satu hari sampah organik Rp.7000 sedangkan nilai ekonomis sampah anorganik sebesar Rp.108.418. Total keseluruhan penjualan sampah organik dan anorganik sebesar Rp.115.418. Dari hasil perhitungan gas rumah kaca dapat disimpulkan bahwa besarnya produksi gas karbondioksida (CO2) pada presentase berat kering sampah cepat terurai sebanyak 205,97 kg menghasilkan gas karbondioksida (CO2) sebesar 673,9 m3 pada kondisi STP, sedangkan pada presentase berat kering sampah lambat terurai sebanyak 56,89 kg menghasilkan gas karbondioksida (CO2) sebesar 14,94 m3 pada kondisi STP Kata kunci : gas rumah kaca, MRF, SOP, timbulan sampah.


Abstract

one of the problems faced PT.X as the company continues to grow is the problem of wate management. althought existing mechanisms such as sorting waste management and lug but not yet fully implemented properly. this will result in increasing the amount of waste. increasing waste generation require increasingly better waste management. one of the effort is to plan the waste management facility which is Material Recovery Facility (MRF). MRF concept was chosen as one of the efforts to manage waste without compromising economic factors. Additionally in this study can find descriptive analysis related to the reduction in greenhouse gas (GHG) emissions due to the construction of MRF that can later be implemented in overcoming the problems of waste management in PT.X Determination of characteristic, composition, and the weight of garbage is done by using plastic containers and weighing over 8 days refers to the SNI 19-3964-1994 and SNI 19-2454-2002. Planning MRF component is based on the calculation of the characteristics, composition and weight of garbage. Standarf Operating Procedure (SOP) is based on the existing operations in the MRF. Analysis of greenhouse gases refee to the book of Tchobanoglous et al, 1993. Result of research conducted during the eight days of heavy organic waste in PT.X is 119,83 kg while for inorganic waste weight amounted to 241,64 kg. Waste density of 612,52 kg/m3. The rate of waste generation employees in 2015 amounted to 0,1646 kg/person/day, while the rate of waste containers in 2015 amounted to 0,0034 kg/container/day. Projections in the number of employees and container yield rate of waste generated by the employees as much as 11,232 kg/person/dat and the rate of waste generated by trash containers as much as 15,17 kg/container/day. Procedure dry and wet waste sorting, sorting goods storage procedures, procedures of organic waste collection, composting process procedures, and storage procedures compost product. The total economic value of organic waste a day Rp 7000 while the economic value of Rp 108.418. Total inorganic overall sales of organic and inorganic waste Rp 115.418. From the calculation of greenhouse gases can be concluded that the amount of production of carbon dioxide (CO2) on a dry weight percentage of trash rapidly unfolding much as 205,97 kg produce carbon dioxide (CO2) amounted to 673,9 m3 on condition STP (Standart Temperature and Pressure), while on a dry weight percentage of garbage slowly decomposes to produce as much as 56,89 kg of carbon dioxide (CO2) 14,94 m3 on condition STP (Standarr Temperature and Pressure). Keywords : greenhouse gases, MRF, SOP, waste.
