It has high economic value. The </em><em>nipa waste </em><em>content was lignin</em><em> which</em><em> can be processed to produce </em><em>second generation of </em><em>bioethanol. It is an alternative material to substitute or mixture of petroleum. Bioethanol made in several stages, sample preparation, pretreatment, hydrolysis, fermentation and purification using distillation</em><em> process</em><em>. The purpose of this study was to compare the enzymatic hydrolysis process and acid in producing high-purity bioethanol.&nbsp; Hydrolysis process using white rot fungus extract&nbsp; as an enzyme and 1.5 N HCl solution (acid) as a hydrolyzing agent. The fermentation stage was used Saccharomyces cerevisiae yeast to convert glucose into bioethanol. Based on the results of the researc</em><em>h</em><em>, the hydrolysis process using enzymes was better of hydrolysis in producing bioethanol rather than acid. The highest purity was 11.78%, while bioethanol produced from the acid hydrolysis process had a purity level of 3.4%.</em></p&gt;}, number={1}, journal={Photon: Jurnal Sain dan Kesehatan}, author={Yuliandani, Reni and Anita, Sofia}, year={2022}, month={Nov.}, pages={36-44} }
