Abstract

Biodiesel is a fatty acid methyl or ethyl esters from vegetable oil or animal fat and is used majorly as fuel in diesel engines vehicles, which is done by esterification process in this research using homogeneous catalyst, the commonly known biodiesel catalysts are homogeneous basic catalysts as Sodium hydroxide and Potassium hydroxide. In this plant design the ultrasonic field induced an affective emulsification and mass transfer so that the mass of ester formation under ultrasonic mixing condition will be higher than that under stirring condition. Emulsification is the first preparation of fat for chemical digestion by specific enzymes. This preliminary plant design represents the study of designing a biodiesel plant capacity of 15,000 ton/year, under Ultrasound agitation in the reactor as the mixing method. Economic analysis of the plant resulted a ROI (Return On Investment) of 26% before cutting the tax to be 21% after tax. POT (Pay Out Time) was calculated to be 2.5 years before tax and 3.5 years after tax. As for BEP (Break Even Point) 53% which means if the plant sell less than 53% there will be no profit. SDP (Shut Down Point) value resulted as 29%, and DCF (Discounted Cash Flow) is 9%. After suggesting to increase the plant capacity to 50% of the original capacity due to low profit and high BEP, According to the economic analysis, this plant has a profit of Rp.183,460,241,614 per year, and of Rp.137,595,181,210 per year after a 25% tax. Percent of Return On Investment (ROI) before tax 80%, after tax 60%. Pay Out Time (POT) before tax is for 1.1 year, and after tax is for 1.5 year. Break Even Point (BEP) value is 28% and Shut Down Point (SDP) value is 16%. Discounted Cash Flow ( DCF) is as much as 26%. According to the previous results, this plant is considered feasible to build in Bontang.
