Abstract
Corn husk with its lignocellulosic content is a potential biomass as a raw material for bioethanol production. However, before it can be converted into bioethanol, corn husks must go through a delignification process, the removal of lignin that binds cellulose so that the next process, namely hydrolysis, can run optimally. Hydrolysis is the next stage, namely the process of breaking the cellulose bonds to become simpler sugar molecules. Therefore, the purpose of this study was to determine the effect of varying the concentration of NaOH and the delignification process time on reducing sugar levels analyzed from corn husk hydrolyzate. The method used in this research is experimental research, where the variations in the concentration of NaOH for the delignification process are 0.5; 0.75; and 1 M, and the processing time is 1.5; 2; and 2.5 hours. Corn husks that had gone through the delignification process were acid hydrolyzed using 21% HCl at 100 oC. The hydrolyzate was filtered to determine the reducing sugar content. The Nelson-Somogyi method by UV-Vis spectrophotometry was used in the analysis of reducing sugar levels. The optimal result of the analysis of reducing sugar content of corn husks is 0.12% using a concentration of 0.5M NaOH and delignification time of 1.5 hours. Based on the results of the study, it was concluded that the delignification process needed to be optimized again because the resulting reducing sugar content was still very low due to the formation of furfural compounds during the acid hydrolysis process.
