PENGARUH LAMA FERMENTASI EM-4 TERHADAP KANDUNGAN PROTEIN KASAR PADATAN KERING LUMPUR ORGANIK UNIT GAS BIO
ABSTRACT: The objective of
this research is to know good duration against the influence of the duration of
EM-4 fermentation by adding EM-4 to increase contents of crude protein for dry
solids of unit organic sludge bio gas. The materials of this research were dry
solids of organic sludge biogas unit resulted from the separation of organic
sludge. The research method was experiments using Completely Randomized Design
with different duration of fermentation treatments as follow 0 hour (P1), 24
hours (P2), 48 hours (P3), and 72 hours (P4) with 6 times recurrences to each
treatments. Data were analyzed using Analysis of Variance (ANOVA) and continued
by Duncan's Multiple Range test if they were significantly different. The
result of Analysis of Variance shows that there was an increase of rough
protein to P1, P2, P3, and P4. Specifically for P4 treatment gave very
different influence (P<0.01) against crude protein contents. The research
suggested adding EM-4 in the fermentation process of organic sludge solids
biogas unit for 72 hour to increase the crude protein content.
