- Fermentation can be defined as a process of anaerobic oxidation of carbohydrate which produces alcohol and carbon dioxide. Batch fermentation is fermentation system closed, where there is no addition of new media, there are no additions (O2), antifoam, acid/alkaline pH control is done in a way. the fermentation process using Saccharomyces cerevisiae producing optimum conditions on the addition of the Saccharomyces cerevisiae of 7% (v/v) and the time of fermentation produces ethanol for 10 days of 20.88% and a residual sugar of 2.44%. Use of microbial Nopkor Mz. held on the addition of the sugar with the levels of 15% (b/v) and time for 8 days of fermentation produces alcohol levels of 9.3%. From the research that has been done, the process of fermentation can take place using Microbe Saccharomyces Cerevisiae, K. Marxianus, Nopkor Mz, and Zymomonas Mobilis, Mz CP4. This research has been conducted on the analysis focusing on the purpose to find out the optimum time and glucose concentration, with a fermentation process for 7 days using glucose off grade and fermiol as well as urea and NPK nutrients as microorganisms. After dilution it is known that the content of glucose in glucose off grade raw materials amounting to 80%. From the results of this process of dilution is done according the levels of variables being run, then fermented for 7 days using fermiol. The best results on the fermentation of glucose levels at 14% and lasted for 6 days that generate levels of bioethanol of 11% (v/v) with the highest percentage yield of 61.63%.
