Abstract

Research on new and renewable energy (EBT) continues to be developed to reduce dependence on fuel oil whose availability continues to decrease. Currently, an alternative energy product that has the opportunity to be developed is bioethanol because it has a high oxygen content so that it burns more completely and is environmentally friendly. Bioethanol can be processed or converted from biomass by the fermentation method. In this study, the use of klutuk banana stems (pseudostem is of Musa balbisina) as raw material will be carried out. Klutuk banana stem is a waste from community agriculture which is known to contain 40% lignin, 44.4% cellulose, and 15% hemicellulose. This research is focused on the initial process of the raw material, namely the delignification process. Delignification process is the process of removing lignin from the material, so that the result of this process is cellulose with a fairly high purity. So far, there have been many studies exploring lignocellulosic biomass as raw material for bioethanol, but there are still few studies examining the effect of the delignification process. Therefore, this study was conducted to examine the effect of NaOH concentration and the effect of time in the delignification process on the decrease in lignin content and the quality of bioethanol produced. The process begins with pre-treatment and delignification with NaOH concentrations of 10%, 20%, 30% and 100 °C, 125 °C, 150 °C, 175 °C, and 200 °C. In delignification, 10% NaOH concentration at 150 °C produced the best cellulose and lignin content with 81.3% cellulose and 10.1% lignin. Pseudostem fibers that have passed the delignification are hydrolyzed and fermented to produce bioethanol.
