Abstract

Bioethanol is commonly used as a fuel; it is renewable, has a high-octane number, and has clean combustion. Indonesia needs to reach 23% in 2025. With enormous palm oil plantation, OPT (oil palm trunk) is a potential alternative source to produce bioethanol by utilizing their sap or lignocellulose from dried palm trunk. The purpose of this research is to find the best method and parameters regarding the inoculum used, temperature of operation, pH, and hydrolysis method to produce bioethanol from OPT. The research method used is the literature review, in which data in this thesis were obtained from research papers, thesis, journals, and reports. This thesis compares two kinds of OPT material, sap and dried. Even though dried OPT produces more bioethanol (44.25%wt) than OPT sap (6.08%v), it was found that the OPT sap is currently far better than dried OPT. Simplicity, viability, and minimum equipment with the non-excessive chemical process and minimum energy required results in a more efficient method of OPT sap process. For bioethanol production from OPT sap, the most optimum bioethanol production parameter conditions are as follows: pH 4.0, temperature 30 °C, and inoculum size of 10% (v/v), and a fermentation period of 24 h with no nutrients added to the process. This method produces 47.5 g/l. of bioethanol.
