Optimizing production of biodiesel from Nyamplung oil with microwave power setting

Abstract

This experimental study examined the processing of biodiesel from Nyamplung oil by microwave power regulation. The aim is to optimize biodiesel yields based on the time process and heating temperature of 650 °C. A suitable method for analyzing biodiesel results is to set the 400 Watts microwave power to 10%, 30%, and 50% of the maximum power. In this process a 1% w/w KOH catalyst is used with a variety of molar ratios of oil-methanol such as 1:6, 1:9, and 1:12. The results showed that the 1:6 molar ratio is the highest percentage of biodiesel obtained with a variation of power of 10% or equal to 40W. The fastest time in this process is 10 minutes. In contrast, the 1:12 molar ratio is the lowest obtained percentage of biodiversity. The higher the temperature and the molar ratio used the fewer biodiesel products are obtained.
