Minyak nabati murni (Pure Plant Oil / PPO) dari kelapa sawit dapat digunakan sebagai subtitusi bahan bakar solar pada mesin diesel. PPO dapat digunakan dengan mencampurkannya dengan solar, sehingga mengurangi penggunaan bahan bakar fosil yang tidak ramah lingkungan. Akan tetapi, bahan bakar campuran PPO juga memiliki sisi negatif seperti Specific Fuel Consumption (SFC) yang tinggi, viskositas tinggi, nilai kalor yang rendah, dan emisi NOx yang cenderung sedikit lebih tinggi. Dalam studi ini berbagai campuran PPO dan solar diuji di PLTD. Hasilnya menunjukkan bahwa PPO sebaiknya digunakan dengan campuran solar dan proses pre-heating dilakukan sebelum masuk ke mesin. Penggunaan PPO juga teruji sebagai bahan bakar yang ramah lingkungan, kandungan sulfur yang rendah, serta menghasilkan emisi gas rumah kaca yang rendah. Agar PPO dapat digunakan pada mesin diesel, maka perlu beberapa perubahan seperti modifikasi mesin seperti pre-heating PPO, modifikasi sistem injektor, dual fuelling, dan blending PPO dengan solar. Kata kunci : biofuel, PPO, kelapa sawit, PLTD, performa mesin diesel

Production of Crude Palm Oil (CPO) is increasing from year to year and is predicted to reach 41.6 million tons per year in 2018. Each ton of CPO will produce 3,28 m3 of POME during the production process. Improper handling of POME, besides causing soil pollution and flying, will release methane gas that categorized as GHG. BPPT cooperate with PTPN V utilized POME to produce biogas and then be converted into electricity in a Biogas Power Plant (PLTBg) in Terantam with a design capacity of 700 kW. The reactor used is a closed Anaerobic Lagoon (CAL) reactor equipped with a recirculation pump. From the evaluations, the technology chosen was not optimal from the operation, its evaluaed from the accumulation of cakes and sludge collected in the reactor which could be disturb during an anaerobic reaction. The next technology development will be carried out with the development of PLTBg in Sei Pagar using CSTR technology. At the same reactor capacity, CSTR has a faster HRT compared to CAL. CSTR is also easier in control of pH and temperature, also requires less land.Keyword : POME, Biogas, CSTR, Covered Lagoon, HRT, OLR
