Pengaruh Suhu Terhadap Pembentukan Bioetanol Pada Tahap Asidogenesis Pengolahan Limbah Cair Palm Oil Mill Effluent(Pome)

---

ABSTRACT
POME (Palm oil mill effluent) has a high chemical oxygen demand
(COD) content of 32,000 mg / L it has the potential for bioethanol formation.
Bioethanol formation is carried out at the acidogenesis stage with anaerobic
conditions. Setting the optimum temperature conditions of anaerobic digesters
can increase microbial growth and activity, affect retention time, use of maximum
substrates and increase the efficiency of bioethanol formation. This research
about the effect of temperature variations of 30°C, 32°C, 35°C on bioethanol
formation, total COD removal, dissolved COD, bacterial growth through volatile
suspended solid (VSS), total volatile acid formation, in the processing of POME
for 5 day. The seeding process is carried out for 5 days using a Circulating Bed
Reactor (CBR) with a working volume of 5 L, the ratio of the substrate to the
inoculum is 50: 50%. The inoculum produced from the seeding stage will be used
as the main research inoculum source. The main research used Erlenmeyer with a
work volume of 400 ml with a substrate: inoculum ratio of 70: 30%. The
increasing temperature of fermentation also increases the level of bioethanol
produced. But on the contrary the decreasing fermentation temperature also
decreases the levels of bioethanol produced, in this research optimum conditions
were reached at a temperature of 35 ° C with the main research results showing
the highest efficiency and bioethanol formation of 13% and 84.61%, removal
efficiency The highest total COD and dissolved COD were 72.72% and 75%; the
highest VSS formation of 2,294 mg / L / day was obtained at 35 ° C, for the
highest TAV formation of 1,255.9 mg / L / day on the 5th day.
