Kajian Tekno Ekonomi Biodiesel Berbahan Waste Cooking Oil sebagai Bahan Bakar Alternatif

Abstract

This research was conducted to analyze the techno-economics of biodiesel made from Waste Cooking Oil (WCO) as fuel and to find out how much electrical power is used to produce biodiesel. The parameters used to measure electrical power are in KWh units and for feasibility in the biodiesel business, namely by using financial ratios which include Break Event Point (BEP), Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period (PBP). The methods used in this research are the Stirring method and the Ultrasonic method. Based on test data, it was found that the method using Ultrasonic is much larger than the Stirring method, namely 0.841 KWh. From the results of the test data calculations, the Capex and Opex values were obtained at IDR 80,474,900 and IDR 7,288,320. The Break Event Point (BEP) value that must be obtained to reach the break-even point in biodiesel production is 14 units (in units) or IDR 183,289 (in rupiah). The Net Present Value (NPV) obtained was IDR 399,057,362 with a positive value, so the business can be said to be feasible. The Internal Rate of Return (IRR) value obtained was 78.83%. Where the rate of return is greater than the 15% rate that has been determined so that investment in biodiesel production is also feasible. The payback period calculation obtained is 1.3 years (1 year 3 months or entering the 2nd year), or if using a cumulative cash flow calculation, a value of IDR 77,545,437 is obtained in the 2nd year.
