Optimum Ratio Between Waste Cooking Oil and Coconut Oilas Raw Material for Biodiesel Production
Biodiesel is a energy that is processed from biological processes and employ agriculture products rather than geological processes. Waste Cooking Oil (WCO) and Coconut Oil (CO) are some of agriculture products that have been applied for this work. The utilization of WCO enables to cycle the waste from the environment and also CO may promote local home industries. The aims of this work are to produce biodiesel from mixture of waste cooking oil and coconut oil. This work is also to study the optimum composition between these two materials (0% to 100% WCO or CO in reverse) in producing biodiesel. Several methods were applied in this work: i.e. esterification, trans-esterification, washing, drying and filtering processes. Some steps of characterization were conducted to fulfil the International Standard (EN 14214).Yield of biodiesel produced was 97.65% with oil mixture composition of50% WCO and50% CO. The FAME component in 50% WCO and 50% CO showed as the nonanoic acid methyl ester (C15H20O2) with composition of 37,79%.
