Produksi Bioetanol Dari Mikroalga Chlorella Sp. Dengan Variasi Konsentrasi H2so4 Dan Volume Inokulum Saccaromyces Cerevisiae

---

ABSTRACT
Microalgae is one type of raw material that is potentially used as bioethanol,
because it has the ability to grow in a relatively short time, can be propagated in
a limited area, and some types of microalgae have high carbohydrate content. The
purpose of this study was to determine the effect of variations in H2SO4
concentration on the glucose produced and determine the effect of variations in
the volume of inoculum volume on the bioethanol produced. The substrate used in
the fermentation process in this study was microalgae Chlorella sp. obtained from
the cultivation of microalgae by fed-batch in the oil palm liquid waste media. The
preliminary stage conducted in this study was the preparation of raw materials
for microalgae Chlorella sp. to form a powder. Microalgae powder was used as a
substrate and hydrolyzed with variations in H2SO4 concentrations of 3%, 4%, and
5%. The hydrolysis solution was then fermented using Saccaromyces cerevisiae
with variations in the concentration of Saccaromyces cerevisiae inoculum volume
of 10% and 12%. The results showed that at 4% H2SO4 (v/v) produced the highest
glucose concentration, amounting to 37,87 mg / mL with the resulting bioethanol
concentration of 19,73 mg / mL at an inoculum volume concentration of
Saccaromyces cerevisiae 12%.
Keywords: bioethanol, H2SO4, microalgae, Saccharomyces cerevisiae
