Pembuatan Bioetanol Dari Limbah Bunga, Akar dan Rambut Jagung (Zea mays L.)

Abstract

Corn plants have many benefits ranging from roots, stems, leaves, flowers, to the hair. Utilization of agricultural waste in corn plants, especially in flowers, roots, and corn silk is still very limited. Judging from the composition of the corn plant which contains lignin, hemicellulose and cellulose which is quite large, the flowers, roots and hair of corn have the potential to be used to make bioethanol. Where this high cellulose content can be obtained through biomass conversion using fermentation technology and microbial activity. The aim of this study was to analyze a ratio of the volume of acid to the level of glucose produced and to determine the level of ethanol produced based on variations in the fermentation time for different materials. The results showed that the average glucose level in cornflowers was 29.3%, corn roots was 26.7%, and corn silk was 27.1%. The highest average ethanol content was produced in cornflower fermentation of 12.64% on the fifth day of fermentation, 10.86% on corn roots on the seventh day of fermentation, and 12.64% on corn silk on the seventh day of fermentation. . With this it can be concluded that the higher the volume of acid given, the lower the glucose level produced and vice versa and the highest percentage of ethanol content was found in flowers and corn silk of 12.64% on the fifth and seventh day of fermentation.
