Ethanol Synthesis from Jackfruit (Artocarpus Heterophyllus Lam.) Stone Waste as Renewable Energy Source
Year: 2015
Type: conference-paper
Abstract: This study was aimed to develop renewable energy from jackfruit's stone. The jackfruit's stone was sliced and dried for 2 d to 4 d afterward the stoness were analyzed for fungi and microbes through microscope. The stone was retrieved from 9 mo and 1 yr shelf life through 2 d to 4 d drying process. The process was made in acid method resulted to high glucose on the solution level 25%, pH 3.5, and temperature 135 ̊C in 3 min. The enzyme method was more simple and resulted 19.24% higher glucose than acid method that is 17.36%. Fermentation was using 0.03 g of Saccharomyces cerevisiae, 0.10 g of urea and 0.05 g of N-P-K on concentration solution of jackfruit’ flour by adding 0.3 mL to 0.7 mL of alpha–amylase, 0.2 mL to 0.6 mL of Gluco-amylase for and fermentation process 3 d to 6 d result of ethanol level is 11% to 13%.
