Methyl Ester factory with raw material of Jatropha Oil and Methanol which has a capacity of 65,000 tons per year is planned to operate for 330 days per year. Factory methyl ester of castor oil was established to meet the fuel needs of alternative energy in view of the depletion of fossil fuels, thus reducing the amount of imported diesel. The factory is planned to be established in Gresik, East Java, with a land area of 20,000 m2 and the number of employees 154 people. Methyl Ester-making process is done by a transesterification process is carried out in a stirred reactor CSTR is by reacting castor oil and methanol. In the process used NaOH as a catalyst. This process takes place in the reactor for 60 minutes with a liquid-liquid phase mole ratio of castor oil with methanol 1: 6 are reversible, exothermic with isothermal conditions, non-adiabatic at 60 ° C and at a pressure of 1 atm. This plant is classified as a low risk operating at atmospheric pressure conditions. Raw material needs of castor oil at 8247.86 kg per hour and methanol amounted to 1775.56 kg per hour. Supporting materials that NaOH at 247.44 kg per hour. Methyl Ester product in the form of 8207.07 kg per hour. The factory was established Methyl Ester require Rp 414,009,351,098.31 fixed capital and working capital of Rp 150 164 569 486. From the economic analysis shows a profit before tax of Rp 119 527 403 866 per year after taxes amounted to 30% profit reached Rp 83,669,182,706 per year. Percent Return On Investment (ROI) before tax after tax 28.87% and 20.27%. Pay Out Time (POT) before tax for 2.6 years and 3.3 years after tax. Break Even Time (BEP) amounted to 52.27%, and Shut Down Point (SDP) amounted to 27.79%. Discounted Cashflow (DCF) accounted for 39.35%. From the data above feasibility analysis concluded that the plant is profitable and feasible to set.
