Abstract
At the moment requirement of fuel increases with the increase population and the development of technology without balanced with reserves of petroleum resources derived from fossil dwindling because it is not renewable. Several countries, including Indonesia started doing a lot of research in the search for renewable fuels, one of which is biodiesel. This research aims to make biodiesel from coconut oil through the transesterification process using microwave. This study uses a mole ratio of oil to methanol (1:9), concentration of KOH catalyst (0.01%; 0.05%; 0.1%; 0.15%; 0.2% and 0.25%), time of reaction (30, 60,90,120 and 150 seconds) and power of microwave (100, 264 and 400 watts). In this research study the effect concentration of KOH catalyst, time of reaction, power of microwave to yield and quality of biodiesel product. Results from this study indicate that concentration of KOH catalyst is 0.20%, time of reaction is 150 seconds and power of microwave is 400 watt and the largest yield of biodiesel product is 93.22%. The quality product of biodiesel in this research complies with biodiesel quality standard ISO 7128: 2012.
