JEJAK KARBON PENGOLAHAN SAMPAH DI tps tlogomas malang Carbon Footprint of Solid Waste Processing At TPS Tlogomas MalangSunarto1, Sudharto P. Hadi2, Purwanto31,2,3Program Doktor Ilmu Lingkungan Universitas DiponegoroAlamat korespondensi : Jl. Imam Bardjo, SH No. 3 Semarang 50241Email: 1) [email protected], 2) [email protected] sector is one of human activities that cause global warming. Decomposition of organic waste in landfill produces greenhouse gas emissions in the form of biogas consisting of methane and carbon dioxide. Solid waste processing in transfer station in the form of recycling and composting product potentially reduce carbon footprint, directly from the reduction in the volume of waste dumped in landfill and indirectly from the recovery of material. The purpose of this study was to determine the carbon footprint of waste processing at the transfer stations of Tlogomas Malang if developed several scenarios to enhance the capacity of processing. Life cycle approach is used to assess carbon footprint of waste management scenarios with the help of software SWM-GHG Calculator. The results showed that the processing of solid waste at current recycling rate of 40,57% – 80,41% (Status Quo) resulted in net carbon footprint of 1.147 ton CO2–eq /year. Increasing of processing capacity to 60 - 88% (Scenario 1) and 90 - 95% (Scenario 2) would reduce net carbon footprint to 801 ton  CO2–eq /year and427 ton CO2–eq/year respectively. If the processing of waste in transfer station of Tlogomas was discontinued (Scenario 3), net carbon footprint increased to 4,063 t CO2-eq/year.Keywords: carbon footprint, greenhouse gases, solid waste processing, life cycle analysis.AbstrakSektor persampahan merupakan salah satu kegiatan manusia yang menyebabkan pemanasan global. Proses dekomposisi sampah organik pada timbunan sampah menghasilkan emisi gas rumah kaca berupa biogas yang terdiri atas gas methana dan gas karbon dioksida. Pengolahan sampah di TPS untuk produk daur ulang dan kompos berpotensi mereduksi jejak karbon secara langsung dari penurunan volume sampah yang dibuang ke TPA dan secara tidak langsung dari pemulihan material sampah. Tujuan penelitian ini adalah untuk mengetahui jejak karbon pengolahan sampah di TPS Tlogomas di Kota Malang jika dikembangkan beberapa skenario pengolahan untuk meningkatkan kapasitas pengolahan sampah yang telah dilakukan selama ini. Pendekatan daur hidup digunakan untuk menaksir jejak karbon dari beberapa skenario pengolahan sampah di TPS dengan bantuan perangkat lunak SWM-GHG Calculator. Hasil analisis menunjukkan bahwa pengolahan sampah pada saat ini dengan tingkat daur ulang sampah sebesar 40,57% – 80,41% (Status Quo) menghasilkan jejak karbon bersih sebesar 1.147 ton CO2–eq/th. Peningkatan kapasitas pengolahan sebesar 60 – 88% (Skenario 1) dan 90 – 95% (Skenario 2) akan menurunkan jejak karbon bersih menjadi masing-masing sebesar 801 ton CO2–eq/th dan 427 t CO2–eq/th. Apabila pengolahan sampah di TPS Tlogomas dihentikan (Skenario 3), jejak karbon bersih yang dihasilkan meningkat menjadi 4.063 t CO2–eq/th.Kata kunci: jejak karbon, gas rumah kaca,  pengolahan sampah, analisis daur hidup.

As part of its mandate, the National Energy Board (NEB) regulates the construction, operation, and abandonment of interprovincial and international pipelines. The primary legislation which directly and indirectly addresses reclamation of NEB lines are the National Energy Board Act and the associated Onshore Pipeline Regulations, 1999, and the Canadian Environmental Assessment Act. The NEB uses a life cycle approach to pursue appropriate reclamation of disturbed rights of way. Initially, reclamation related issues are addressed at the application stage. Subsequent to the application process, the actual implementation of reclamation measures occurs during construction of the line. Success of reclamation is monitored during the operational life of a line through inspection and auditing procedures, with additional measures being implemented as necessary.
