Abstract

The factory design for making bio-char from rice husks using a slow pyrolysis process has a capacity of 25,000 tons/year and operates for 330 days a year. The amount of rice husks required to reach annual production capacity is 17,102.06443kg/hour. A factory for making bio-char from rice husks using a slow pyrolysis process is planned to be established in Licin District, Bnayuwangi Regency, East Java. The land area required is 9.163 m2. The planned form of company organization is a Limited Liability Company (PT) with a line and staff organizational structure, and a total of 204 employees. The results of the economic analysis on the pre-design of this factory are as follows:  Fixed-Capital Investment (FCI) = Rp 112.472.221.574  Working Capitas (WC) = Rp 1.161.349.095.439  Variable Cost (VC) = Rp 1.086.313.022.424  Total Sales = Rp 1.086.313.022.424  Profit Margin (PM) = 20,79 %  Break Even Point (BEP) = 36,45 %  Return on Investment (ROI) = 15,849 %  Pay Out Time (POT) = 6,30 year  Return on Netwrk (RON) = 26,41%  Internal Rate of Return (IRR) = 15,32 % Based on the results of the analysis from technical aspects, economic aspects and environmental aspects, it can be concluded that the manufacturing factory bio-char from rice husks using a slow pyrolysis process is feasible to establish.
