Production and Performance Test of Biodiesel Produced from Waste Cooking Oil

Abstract

Biodiesel has become an important source as a subtitution fuel for diesel engines. As an alternative fuel for diesel engines, it is becoming increasingly important due to diminishing fossil fuel reserves and the environment consequeness of exhaust gases from petroleum fuelled engines therefore, it needs to be further investigated how biodiesel blend percentage could affect the performance and emission of diesel engine. Waste cooking oil (WCO) is one of the raw material for Biodiesel. WCO that has been converted into biodiesel is made using esterification and transesterification methods. Then, biodiesel is mixed until it has the composition of B20, B30 and B50. The mixture is then tested for performance and emissions. In testing, B30 did not have a significant decrease in performance but the emission test results (opacity) were higher than B20. B50 has a significant decrease in performance when compared to B20, but has the lowest opacity test results.Biodiesel merupakan sumber energi terbarukan yang berasal dari minyak nabati. Penggunaan biodiesel sebagai bahan bakar mesin diesel di Indonesia, akan terus meningkat hingga mencapai B100. Salah satu bahan baku yang dapat digunakan untuk memproduksi biodiesel adalah minyak jelantah. Pembuatan biodiesel dari minyak jelantah, dibuat menggunakan metode esterifikasi dan transesterifikasi. Kemudian biodiesel dicampur dengan bahan bakar minyak diesel hingga memiliki komposisi campuran B20, B30, dan B50. Setiap campuran akan dilakukan pengukuran performa dan emisinya. Dalam pengujian ini, B30 tidak mengalami penurunan performa yang signifikan namun hasil uji emisi (opasitas) lebih tinggi apabila dibandingkan dengan B20. B50 mengalami penurunan performa yang signifikan jika dibandingkan dengan B20, namun memiliki hasil uji emisi (opasitas) yang paling rendah
