Abstract: This research focuses on the optimization of bioethanol production from palm waste by minimizing energy consumption and scheduling the production line. Commercial software named ASPEN Plus Suite is used, including Aspen Plus, for studying the bioethanol production process from oil palm trunk, Aspen Batch Process Developer for scheduling the minimum time operation, Aspen Energy Analyzer for minimizing energy consumption by pinch analysis, and Aspen Plus Dynamics for studying the process dynamic. The minimum process operation time can achieve by batch scheduling and Gantt chart. In steady-state condition, it can conclude that bioethanol production from oil palm trunk can produce ethanol 10,592.22 litter per day by using oil palm trunk 47,208 kg per day and in part of bioethanol production from empty fruit bunch can produce ethanol 13,950 litter per day by using oil palm trunk 47,208 kg per day. The production schedule can introduce the system to operate simultaneously between batch and continuous processes by using an overlapping operation of the subsequent processing batch. It can reduce the interval time of equipment significantly. Bioethanol production from oil palm trunk use 3 tanks of SSF process (simultaneous saccharification and fermentation) proposes the target of bioethanol every 24.5 hours rather than every 60.5 hours by a single tank and bioethanol production from oil palm empty fruit bunch also use three bioreactors of simultaneous saccharification and fermentation (SSF) proposes the target of bioethanol every 24.5 hours rather than every 72.5 hours by a single tank. Bioethanol production from oil palm trunk with/without heat exchanger network has the totals cost per year at 691,481.9 $/year and 789,374 $/year, respectively. The implementation of a heat exchanger network can reduce costs around 12.40% per year. In the part of bioethanol production from oil palm, empty fruit bunch without/with heat exchanger network has the totals cost per year at 1,006,063.4 $/year and 1,343,861.4$/year, respectively. The implementation of a heat exchanger network can reduce costs around 25.14% per year. Finally, both bioethanol production from oil palm trunk and oil palm empty fruit bunch is simulated by Aspen Plus Dynamic in terms of process dynamics & control for adding controller into both simulations.
