Abstract

Kepok banana’s peel is a huge and unused organic waste. Kepok banana’s peel is about 11,48%. Bioethanol from it can increase economic value and reduce organic waste of banana’s peel in society. The aim of research was to identify the impact of starter concentration and fermentation period to bioethanol level on the fermentation of kapok banana’s peel. The research conducted on December 2012 – February 2013 at Microbiology Laboratory of Teacher Training Program Study of Biology Muhammadiyah University of Purwokerto. The research method was experiment that used Random Sampling Factorial with 2 factors were starter concentration (3%, 5%, 7%, 9%) and fermentation period (6, 9, 12 days) with 3 repetitions. Starter was from inoculums Saccharomyces cerevisiae in quantity and physiologic condition that was ready for inoculated on the media of kapok banana’s peel. Research parameter was bioethanol level. Data analysis used analysis of varians (anova) and if there was significant difference, it would get Duncan Multiple Range Test (DMRT) on 5% level test. The result showed that starter concentration and fermentation period gave significant impact to the production of bioethanol level (P<0,05). Starter concentration 7% with fermentation period for 6 days (S7L6) was the best action in production of highest bioethanol about 5,35%.
