Abstract

The main objective of this study is to find the the optimum conditions for the biodiesel production where it involved the control parameter of molar ratio, reaction temperature, reaction time and catalyst concentration. Biodiesel production methods that used in this study is via transesterification which includes pre-processing process, transesterification, washing and drying process. All of the biodiesel production is carried out in the laboratory scale by using waste vegetables oil (WVO), methanol and potassium hydroxide (KOH). The experiment were conducted of control parameter selected as follows : 0.5 wt.% and 0.9 wt.% of KOH, 30 and 60 minutes of reaction temperature, 4:1 and 6: 1 molar ratio methanol to oil, and 60 °C of reaction temperature. The highest yield was achieved under optimum condition at 60 °C of reaction temperature, 60 minutes reaction time, 0.5 wt.% of catalyst concentration, and 4:1 molar ratio. Under the optimum condition, the highest yield percentage was reached at 95.52%. The result was noted that the reduction of molar ratio from 6:1 to 4:1 and catalyst concentration from 0.9 wt.% to 0.5 wt.% produced the higher value of coversion efficiency (yield). Futhermore, the yield percentage of the experiment was varied from 82.5% to 95.52%.
