Produksi Bioetanol Dari Bungkil Inti Sawit Berdasarkan Kondisi Optimum Proses Hidrolisis Dengan Variasi Konsentrasi Ragi

---

ABSTRACT
Indonesia is a country with a growing human population, causing the need of
energy also increases. Bioethanol has been widely used in transportation as a fuel
that is increasingly reduced. Palm kernel expeller has a high enough potential to
be developed into an alternative energy source, namely bioethanol because of its
lignocellulosic content. The purpose of this study was to determine the composition
of yeast in the fermentation process, and determine the optimal processing time for
the formation of bioethanol in the Hydrolysis and Separate Fermentation (SHF)
method. The stages in this study were the hydrolysis of palm kernel expeller using
H2SO4 3M for 5 hours at 100 oC. The fermentation process is carried out with
variations in time for 24 hours, 48 hours, 72 hours, 96 hours and 120 hours. The
fermentation process is carried out with variations composition of yeast for 4 g/L,
6 g/L, dan 8 g/L. The results showed that in the fermentation using a sugar
concentration of 22,11 g/L, obtained an optimal fermentation in 2,5 % (v/v) or
19,73 g/L at 6 g/L composition of yeast and 96 hours time on fermentation. The
greater the concentration of Saccharomyces cerevisiae and the longer fermentation
time, the more bioethanol is obtained.
Keywords: Bioethanol, fermentation, palm kernel expeller, Saccharomyces
cerevisiae.
