ABSTRACT

BananaI peel is a waste, and a lignocellulose biomass used as an alternative raw material to bioethanol by utilizing the enzymatic ability of Aspergillus fumigatus. ThisIstudy therefore was conducted to test the potential of banana peel to be converted into bioethanol. TheI research started by cultivatingi A. fumigatus on Potato Dextrose Broth media with the banana peel mechanically converted into powder and used as a substratei. This wass followed by the pretreatment process by adding A. fumigatus to the substrate container in ratios of 1: 1, 1: 5, and 1:10, respectively. Furthermore, thei gravimetric method was used to determine the level of lignin due to pretreatment with contact times of 24, 72, and 120 hours. This was preceded with the hydrolysisi stage using the DNS method to measure the amount of sugar produced, with the removal of the highest lignin content at the pretreatment stage of 7.3% and the highest sugar level at the hydrolysis stage of 1.353 g/L. This research shows that banana peell contains lignocellulose and has the ability to be used as raw material for bioethanol. Therefore, to iincrease the levels of bioethanol derived, it is necessary to carry out a fermentation process and further research.
