Various biodiesel production processes through transesterification reaction with a variety of catalysts have been developed by previous researcher. This process still has the disadvantage of a long reaction time, and high energy need. Dielectric Barrier Discharge (DBD) plasma electro-catalysis may become a solution to overcome the drawbacks in the conventional transesterification process. This process only needs a short time reaction and low energy process. The purpose of this study was to assess the performance of DBD plasma rector in making biodiesel such as: the effect of high voltage electric value, electrodes gap, mole ratio of methanol / oil, and reaction time. The Research method was using GC-MS (Gas Cromatography-Mass Spectrofotometry) and FTIR (Fourier Transform Infrared Spectrofotometry) and then it will be analysed the change of chemical bond between reactant and product. So, the reaction mechanism can be predicted. Biodiesel is produced using methanol and palm oil as reactants and DBD plasma used as reactor in batch system. Then, reactants contacted by high voltage electric. From the results of this research can be concluded that the reaction mechanism occurs in the process is the reaction mechanism of cracking, the higher of electric voltage and the longer of reaction time lead to increasing of product yield. The more of mole ratio of methanol / oil and widening the gap between the electrodes lead to decreased product yield. From this research, product yield maksimum is 89,8% in the variable of rasio mol metanol/palm oil 3:1, voltage 10 kV, electrode gap 1,5 cm, and reaction time 30 seconds. }, issn = {2460-9919}, pages = {116--122} doi = {10.14710/teknik.v34i2.5636}, url = {https://ejournal.undip.ac.id/index.php/teknik/article/view/5636} }
