Pengaruh Konsentrasi Yeast Saccharomyces Cerevisiae Dan Waktu Fermentasi Terhadap Pembentukan Bioetanol Dari Mikroalga Chlorella Sp.

---

Bioethanol is an alcohol produced from the fermentation process. Bioethanol is
also called ethyl alcohol, which is produced through a microbial process, which is
the opposite of ethanol synthesized from petrochemical sources. Microalgae
Chlorella sp. can be used as raw material for bioethanol by utilizing
microorganisms. Microorganisms used to process microalgae Chlorella sp. to
become bioethanol is Saccharomyces cerevisiae. The purpose of this study was to
determine the effect of Saccharomyces cerevisiae yeast concentration on
bioethanol formation and determine the effect of fermentation time on bioethanol
formation. This research phase consisted of hydrolysis, inoculum making,
bioethanol fermentation, separation and analysis of bioethanol concentration. The
variation of bioethanol fermentation time is 1, 2, 3, 4 and 5 days, while the
variation of Saccharomyces cerevisiae concentration is 0.2%; 0.4%; 0.6% and
0.8% (w/v). The optimum fermentation results is bioethanol 2% (v/v) or 15.876
g/L. This optimum bioethanol concentration was obtained on the 5th day of
bioethanol fermentation with a yeast Saccharomyces cerevisiae concentration of
0.6% (w/v).
