They are considered to be promising feedstocks for bioconversion into value-added products such as bioethanol. However, using these lignocellulos ic materials to produce bio ethanol remains a significant challenge for small and medium enterprises. Hence, techno-economic and sensitivity analys es of bioethanol plant simultaneously treating these materials were performed in this study . The information based on preliminary experimental data in batch operations w as employe d to develop a simulation of an industrial-scale semi-continuous production process. Calculation s of mass balance , equipment sizes , and production cost estimation of the production plant of various capacities ranging from 10,000 L/day to 35,000 L/day were summarized. The result based on 20 years of operation indicated that the n et p resent v alue of the plant of lower capacities was negative. However, this v alue became positive when the plant operated with a higher capacity, 35,000 L/day. The highest ethanol yield, 294.84 L EtOH /ton feedstock , was produced when the plant treated only an empty fruit bunch generating 8.94% i nternal r ate of r eturn and US \$ 0.54 production cost per unit. Moreover , the higher oil palm trunk ratio in the feedstock, the lowe r ethanol yield contributing to the highe r production cost per unit . }, pages = {319--328} doi = {10.14710/ijred.9.3.319-328}, url = {https://ejournal.undip.ac.id/index.php/ijred/article/view/29568} }
