CONCLUSION
Dewaka banana can be used as an alternative energy source with bioethanol concentration of 84.43% from
the results of gas chromatographic analysis. The ethanol content of a fermented for 5 (five) days with a fermentation
material fermipan. The hydrolysis which is used was acid hydrolysis using hydrochloric acid. The optimum
concentration was 1.5 N HCl, the optimum temperature hydrolysis was at 900C, while for the optimum hydrolysis
time was 70 minutes.
Furthermore, it is necessary to do further analysis on the part of others such as banana stems and leaves were
harvested after not being used anymore.
