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.
