PRARANCANGAN PABRIK BIODIESEL DARI MIKROALGA DENGAN KAPASITAS 8.500 TON/TAHUN

This Biodiesel Plant will be established in Indramayu, West Java started in this year with the capacity 8500 tons/year. Begin with the microalgae cultivation process which is need at least 1 year to overcome the highly mass production. We need 382.5 liter of microalgae to be cultivated in the beginning. Total area needed is about 14.5 hectares, 90% of it is utilizing as cultivation area. To produce biodiesel, we use reactive distillation technology through 2 steps of heterogeneous reaction, esterification and transesterification. The raw materials are 39610.368 kg/hr of microalgae, 25936.86888 kg/hr of n-hexane as the solvent in extraction process, and 3341.9232 kg/hr of methanol. The utilities unit includes water at the rate of 56.0071 m 3 /ton of product and electricity at the rate of 28.4737 kW/ton of product. Based on economic analysis, the biodiesel plant has the following results: 1. Fixed Capital : Rp144,555,036,100.9 2. Working Capital : Rp27,770,748,480.07 3. Profit before taxes : Rp47,999,833,203.39 4. Profit after Taxes : Rp23,999,916,601.69 Feasibility Study Calculation Requirement ROI after Taxes 16.60% 11% minimum POT after Taxes 3.72 year 5 years maximum BEP 42.78 % 40-60% SDP 19.87% DCFRR 30.88% 18% minimum Based on the data above, the biodiesel plant from microalgae with capacity 8500 ton/year is potential to be established
