Abstract


Abstrak

Cadangan bahan bakar fosil yang bersifat tidak dapat diperbarui semakin menipis. Pengembangan energi terbarukan perlu dilakukan untuk mengurangi ketergantungan terhadap bahan bakar fosil, diantaranya dengan pemanfaatan minyak nabati menjadi biodisel. Pada penelitian ini digunakan bahan baku biodisel campuran minyak jarak dan biodisel minyak jelantah yang dikombinasikan dengan minyak solar. Tujuan penelitian ini adalah untuk mengetahui kinerja dari mesin disel dengan menggunakan bahan bakar solar 100% dan campuran biodisel jarak – jelantah dan solar dengan variasi 5% biodisel – 95% solar (B5), 10% biodisel – 90% solar (B10) dan 15% biodisel – 85% solar (B15). Penelitian dimulai dengan melakukan pengujian sifat fisis bahan bakar meliputi viskositas, densitas, flashpoint, nilai kalor. Selanjutnya dilakukan uji unjuk kerja mesin disel. Hasil penelitian menunjukkan bahwa daya yang dihasilkan dari bahan bakar B5, B10, B15 masih lebih rendah daripada bahan bakar solar murni. Laju konsumsi bahan bakar pada biodisel B5, B10, dan B15 lebih rendah dibanding bahan bakar solar murni.

 

Abstract

Reserves of non-renewable fossil fuels are diminishing. Renewable energy development needs to be done to reduce dependence on fossil fuels, including the utilization of vegetable oil into biodiesel. This research used a mixture of jatropha and waste cooking oil biodiesel combined with diesel oil. The purpose of this study was to determine the performance of diesel engines using 100% diesel fuel and biodiesel with a variation of 5% biodiesel - 95% diesel (B5), 10% biodiesel - 90% diesel (B10) and 15% biodiesel - 85% diesel (B15). The study has begun by testing the physical properties of the fuel, including viscosity, density, flashpoint, heating value. Then the diesel engine performance test was carried out. The results showed that the power produced from B5, B10, B15 fuels was lower than pure diesel fuel. The fuel consumption rate of B5, B10, and B15 biodiesel is lower than pure diesel fuel.
