Abstract

Increasing fuel demand has an impact for decreasing fossil energy reserves. One of the government ways to solve this problem is by increasing the production of biomass fuels, for example biodiesel. Biodiesel can be produced from waste cooking oil through the transesterification stage that reacts oil molecules with alcohol and catalyst to produce methyl esters. Heating method that can be used is microwaves method. This method utilizes wave emission which is absorbed by the sample to make sample’s temperature being higher than surface’s temperature of the reactor’s wall. In the process of making biodiesel, there are several factors that affected heating process. There are ratio of waste cooking oil and methanol, an amount of catalyst, reaction temperature, voltage, and distance of electrodes. The effect of that factors can be seen from the result of the biodiesel’s rendement. From this research, we had ratio 5:1 of waste cooking oil and methanol got 85,. % rendement, 2% of catalyst got 87.12% rendement, 60oC reaction temperature got 88.88% rendement, 10 kV got 89.12% rendement, and 1 cm of electrode’s distance got 86.34% rendement. This result suggests that a biodiesel production prototype with microwaves and high voltage utilization can produce a high percentage of biodiesel rendement

Abstract

Kerupuk and kemplang industries produce at least 65 liters of waste cooking oil per production. One form of the application of science and technology in the field of new and renewable energy can be done in processing the waste oil from industrial production through the conversion process into one of the environmental friendly alternative fuels, biodiesel. Biodiesel production process can be carried out by various methods, such as utilizing induction heating technology. This technology has non-contact properties that do not interfere with the reactions that occur because of its application, which produces heat from the workpiece. This study uses waste cooking oil as raw material with variations in the molar ratios 1:3, 1:4, 1:5, 1:6, and 1:7. The analysis showed that the maximum biodiesel production was used of 1: 7 molar ratio with 86.95% yield, 0.86 gr/cm3 of density, 5.73 cSt of viscosity, 190oC of flash point, and 0.44 mg-KOH/gr of acid number. The using this ratio produces maximum yield and following SNI.
