<![CDATA[Waste water produced from Crude Palm Oil’s process in Palm Oil Mill (POM) is usually treated using water treatment ponds that consist of anaerobic ponds and aerobic ponds. It is known well, methane gas is generated from degradation of organic matter in anaerobic ponds. The methane gas results global warming impacts. Regarding to tackle the global warming impact, the methane gas generated from POM can be captured and flared to convert methane gas tocarbon dioxide. This study was conducted in one of the big capacity of Pinang Tinggi POM owned by PT Perkebunan Nusantara 3. Methane gas potential was investigated by using pH, COD (Chemical Oxygen Demand) and waste water measurement. And from these result the methane gas potential was predicted. In this study, using Clean Development Mechanism (CDM), capturing methane gas generated from anaerobic pond gave a result that the project can be an economically feasible based on the condition measured.Keywords : oil palm industry, methane gas, gas rumah kaca, CDM project(CleanDevelopment Mechanism), COD (Chemical Oxygen Demand)]]>

<![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[In this study, the effect of diameter particle and the effect of inter-particlecohesion force due to liquid bridge formation on the minimum fluidization velocityin the fluidized bed have investigated. Also the effect of inter-particle cohesionforce on a fluidization condition of the bed has observed by video camera. Theinvestigation results showed bigger diameter can give higher minimumfluidization velocity, and stronger inter-particle force can give higher minimumfluidization velocity, and then make a quality of fluidization of bed lower. Usingwith this investigation results, the mechanism of fouling and slaggingphenomena, which are happen in the coal-fired boiler can be explained.Kata kunci: fluidized bed, minimum fluidization velocity, particle diameter,relative humidity, inter-particle cohesion force]]>

<![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.]]>

<![CDATA[The use of Pure Plant Oil (PPO) as a fuel blend in a power plant is mandatory as stipulated in the Ministerial Decree of Energy and Mineral Resource of the Republic of Indonesia. However, the implementation of PPO used in power generation has many obstacles due to a lack of information concerning the impacts of PPO used in the operating performance of the power generation engine. In this study, the effect of PPO as a blended fuel with High-Speed Diesel (HSD) was studied by using the gas turbine with a capacity of 18 MW. The PPO was blended based on volume with a ratio of 0%, 5%, 10% and 20%. As the results, it is shown that the use of PPO with a blend ratio of 20% is the maximum fuel blend ratio according to the threshold value of a flue gas temperature and a vibration velocity in the gas turbine.]]>

<![CDATA[Renewable energy fueled power generations are few developed by private sector in Indonesia. High-cost investment and low electricity selling price to PT PLN as a single buyer is main barriers for private sector to involve in the development of renewable energy fueled power generations. In this project, the economic feasibility of Mini Hydro Power Plant of Cikaso with capacity of 5.3 MW, located at Sukabumi Regency, West Java province was assessed. This project utilized revenue generated from carbon market to increase the economic feasibility. Procedure to register the project to United Nation for Climate Change Convention (UNFCCC) as a Clean Development Mechanism project was explained in detail. Approved Consolidation Methodology (ACM) 0002 Version 12.3.0 was used to calculate grid emission factor in Jawa-Bali-Madura the grid electricity system. It was calculated that the grid emission factor is 0.833 (t-CO2/MWh), and the carbon emission reduction generated for this project is 21,982 ton/year. From the analysis result, it can be proven that the additional revenue from carbon credit could increase the project IRR from 10.28% to 13.52%.]]>

<![CDATA[Utilization of empty fruit bunch (EFB) waste as a fuel for power electric generation is one of the options available for palm oil factory in the effort to reduce EFB waste. At the moment, there are several options to utilize EFB waste such as fertilization and composting. However, both ways show ineffective result, particularly in handling huge amount of EFB. Up to now, Indonesia only has a limited number of EFB fueled power plants. This paper explains technically and economically EFB fueled power plant supplying to PLN grid in Pinang Tinggi Palm Oil Factory located at Sei Bahar, Jambi Province. The economical feasibility is low, if the additional revenue generated from selling remnant oil, selling ash of EFB and selling credit carbon are not counted as an income. Using these additional revenues, the IRR project increased from 2.03% to 15.12%. The investment cost and the selling electricity price are critical sensitivity factors for project economics. ]]>

<![CDATA[Indonesia is a country having a big biomass potential. This is proven by the fact tahat experts from many developed countries have visited Indonesia to explore and to utilize biomass waste. Utilizing biomass waste as a substitute for fossil fuel is one of the valuable opportunity to implement CDM project for energy sector in agro industry in Indonesia. In this paper eight kinds of biomass wastes potential in Indonesia were theoretically analyzed, then the results were compared with real condition of the biomass waste in sites. Several sites were explored to investigate eight kinds of biomass waste.The utilization and availability of those biomass waste potential as a fuel for power generation in recent conditon is discussed and then the opportunity level for utilization of the biomass wastes is qualitatively described in this paper.]]>
