Abstract

Bioethanol is a bioefuel from lignocellulosic biomass fermentation with microbes or bacteria. Indonesia the need for fuel oil is very high so that still importing and depletion of the availability of petroleum. To overcome this, its necessary to establishe a bioethanol from coffe skin for demand of fuel oil in Indonesia. Preliminary plant design of bioethanol from coffe skin will designed with a production capacity of 53.000 tons/year and operates for 330 days a year. The business entity form of this factory is planned as a Limited Liability Company (PT) and a workforce of 187 people. The results of the pre-designed economic analysis of the factory for making bioethanol from coffe skin are as follows: • Total Invesment Capital = Rp. 1.087.364.098.648,- • Total Production Cost = Rp. 856.345.643.535,- • Sales Proceeds = Rp. 1.154.042.693.530,- • Net Profit = Rp. 196.981.598.571,- • Profit Margin = 24,38% • Break Event Point = 31,91% • Return on Invesment = 18,12% • Pay Out Time = 5 year 6 month • Return on Network = 30,2 % • Internal Rate of Return = 39,41 % Based on the results of the economic analysis, it can be concluded that the factory for making bioethanol from coffe skin is feasible to establish.
