DENSITAS BIODIESEL DARI MINYAK JELANTAH DENGAN METODE NONKATALIS

Abstract

The need for fuel is increasing along with advances in technology, industry and transportation, both in Indonesia and the world. The transition to renewable forms of energy as a cleaner alternative energy has begun in many countries, for example biodiesel which is expected to meet fuel needs, one of the materials that can be made into biodiesel is used cooking oil. The aim of this research is to determine the density value of biodiesel from used cooking oil. This research is using experimental method. The transesterification process takes place in a Bubble Colum Reactor (BCR) at a temperature of 150 °C. The molar ratios between methanol and used cooking oil are 160, 170, and 180. The results of this research produce density values of 889.6 Kg/m3, 888.6 Kg/m3, and 885.2 Kg/m3 and produce the best yield levels of 31.33%.

Keywords: used cooking oil, biodiesel, molar ratio, density, transesterification
