<![CDATA[Water waste in Palm Oil Mill (POM) is not effectively utilized yet. Before waste water discharge from POM, the waste water is processed by an aerobic treatment in several ponds to decrease the influence of organic matter. Methane gas generated in the anaerobic ponds is a Green Gas House giving a contribution to global warming impact. In Palm Oil Mill of Sei Silau located in North Sumatera, the potential generated methane gas in two anaerobic ponds has been investigated using measurement of Chemical Oxygen Demand (COD) of waste water in the sites. Based on the potential generated methane gas, the reduction of GHG emission is calculated, and the feasibility of the project as CDM project was evaluated.Keywords : Pabrik Kelapa Sawit, gas metana, gas rumah kaca, proyek CDM (CleanDevelopment Mechanism),, COD (Chemical Oxygen Demand)]]>

<![CDATA[The methodology of calculation for emission factor for grid connection is determined by IPCCC Intergovernmental Panel Climate Change). The methodology is revised periodically,and become comprehensive calculation. Mainly in developed countries, the emission factor is provided by government related institution yearly. Therefore the developers who need that value can get easily, and they can save a time and money in the developing Clean Development Mechanism Project. In Indonesia, until now there is no government institution or other related institutions that have an obligation to provide and calculate that number.PTPSE-BPPT has initiated to calculate the emission factor of grid system of Jawa-Madura-Bali using data between 2002 and 2006. The Approved Consolidated Methodology 0002 and Approved Methodology Simple I-D were used in the calculation. Based on the calculationresult, it was proved that the emission factor of JAMALI grid increased 18.2%, resulted to coal consumption increased. The value of this emission factor has been adopted by Directorate General Electricity and energy Utilization and recognized by Indonesian Designated National Authority, as a National Number of emission factor in JAMALI in 2008.Keywords : faktor emisi, emisi karbon, sistem JAMALI, pembangkit listrik,Clean Development Mechanism,]]>

<![CDATA[Pada akhir Maret 2017, telah dikeluarkan regulasi baru oleh Pemerintah terkait harga jual listrik. Sayangnya,harga jual listrik yang baru ini lebih rendah dari pada harga jual listrik sebelumnya. Penetapan harga baru ini akan menurunkan tingkat keekonomian dari pengoperasian pembangkit listrik tenaga biogas (PLTBg), sehingga pembangunan PLTBg di Indonesia menjadi kurang menarik bagi para investor. Kondisi ini sangat tidak baik bagi iklim pembangunan energi terbarukan di Indonesia. Untuk itu berdasarkan studi kasus pembangunan PLTBg Terantam, Riau maka direkomendasikan pemanfaatan gas metana tidak hanya sebagai bahan bakar PLTBg saja tetapi juga sebagai pengganti sebagian bahan bakar cangkang di boiler PKS. Makalah ini membuktikkan kenaikan tingkat keekonomian dari hasil penjualan cangkang untuk PLTBg dengan kapasitas 1.025 kW. Estimasi ketersediaan jumlah gas metana dilakukan dengan menggunakan metodologi UNFCCC (United Nations Framework Convention on Climate Change). Dengan adanya pendapatan tambahan, IRR naik dari 11,45% menjadi 16,41% dan NPV naik dari  Rp. -1.086,4 x 106 menjadi  Rp 3.717,85 x 106.]]>

<![CDATA[Waste water utilization in palm oil mills (POMs) in Indonesia is limited only for land application and in some palm oil mills the waste water is unutilized and it is only discharged to a river. The technology of methane gas utilization produced from waste water have been developed, unfortunately economical barrier is a big problem to implement it in the POMs. Since Clean Development Mechanism (CDM) have been being introducing in Indonesia, many foreign investors who looking for Certified Emission Reduction (CER) visit and investigate potential reductions in Indonesia. Using CDM Mechanism, it will change feasibility of an activity of methane gas capture. An income from selling CER makes theeconomical feasibility of methane gas capture increase. The purpose of this study is to investigate the potential methane gas produced in waste water pond in all POM owned by PTPN V, located in Riau Province. Area of own plantation, amount of processed (Fresh Fruit Bunch (FFB) and distance of the location are proposed as a consideration for selecting candidate locations. The potentialmethane gas captured was calculated. It was known that four POMs have a potential methane gas amount produced from waste water pond, and the investment in those locations were feasible based on the NPV calculation result. Utilization of captured methane gas as a fuel for power generation is inconsiderate, because negotiation is predicted will be takes a long time.Key words: green house gasses, palm oil mill, empty fruit bunch, fresh fruit bunch, palm mill oil effluent, clean development mechanism]]>

<![CDATA[Umumnya di dalam pemanfaatan air limbah di Pabrik Kelapa Sawit (PKS) Indonesia terbatas hanya untuk aplikasi daratan. Teknologi untuk menangkap dan memanfaatkan gas metana yang dihasilkan dari kolam anaerobik pengolahan air limbah telah dikembangkan, akan tetapi halangan ekonomi merupakan masalah besar untuk menerapkan teknologi ini. Karena Mekanisme Pembangunan Bersih (CDM) telah diperkenalkan di Indonesia, teknologi untuk menangkap dan memanfaatkan gas metana mempunyai peluang untuk diterapkan. Menggunakan revenue CDM, investor asing mempunyai kesempatan untuk menginvestasikan instalasi untuk menangkap dan membakar gas metana yang dihasilkan dari kolam anaerobik pengolahan air limbah di PKS. Sebagian dari mereka memanfaatkan gas metana yang ditangkap sebagai bahan bakar untuk menggantikan bahan bakar fosil. Di dalam studi ini, potensi pengurangan Gas Rumah Kaca dari gas metana di PKS PT. Perkebunan Nusantara VI diteliti. Menggunakan AMS-III.H (Approved Methodology) mengenai metodologi recovery metana di dalam pengolahan limbah dan AMS-I.D mengenai pembangkitan energi listrik terbarukan yang terkoneksi dengan jaringan grid , potensi gas metana yang ditangkap dan listrik yang dibangkitkan dihitung. Ada dua jenis revenue yang mungkin diperoleh dalam proyek ini, yaitu satu dari penjualan karbon kredit ke para pembeli CER (reduksi emisi yang bersertifikat), dan yang lainnya dari penjualan listrik ke PT. PLN (Perusahaan Listrik Negara). Telah diketahui terdapat dua PKS yang layak menerapkan teknologi ini.]]>
