Summary: | Agricultural wastes contain lignocellulose components consisting
cellulose, hemicellulose, and lignin. Cellulose can be converted into glucose using
cellulase enzymes. Glucose resulted from the process will be able to be used as
material for bioethanol production. The ease of cellulosic hydrolysis in
agricultural waste varies depending on the crystallinity of cellulose and the
existance of lignin and hemicellulose within the waste.
The study was conducted by analyzing the initial lignocellulosic
composition of each wastes and the cellulose crystallinity index of the waste. To
determine the level of ease of hydrolysis of cellulose, the Cassava Peel, Cocoa
Peel (Pod), Banana Peel, Pineapple Peel and Pineapple Core are hydrolyzed by
commercial cellulase enzyme �celluclast� with activity of 100 FPU/ml at a
temperature of 50oC for 72 hours.
The results showed that lignin has major role to hold up cellulose
hydrolyzed rather than hemicellulose and cellulose crystallinity index. Sample
with the highest level of hydrolysis ease is the pineapple core with a value of %
CCR (Cellulose Conversion Ratio) 87.34. While the sample with the highest
glucose production is pineapple peel with 152.4 g of glucose/kg of waste.
