The research was aimed to evaluate the effect of biogas liquid waste as a fermentation starter of rice husk to the nutrient content, gross energy and bulk density. The method used laboratory experiment using a completely randomized design (CRD) on factorial pattern (6 x 5) with the level of biogas waste liquid : P0-treatment (0% negative control), P0+ (Cellulomonas sp as positive control), P1 (5%), P2 (10%), P3 (15%), P4 (20%) ml/g, and the incubation time : T0 (0 day control ), T1(7 days), T2 (14 days), T3 (21 days) and T4 (28 days). The variables measured was the content of ash, crude protein, crude fiber, crude fat, gross energy and bulk density. Data were analyzed by analysis of variance (anova) CRD Factorial pattern and if there is a significant difference was followed by Duncan's Multiple Range Test. The results of research was the level of biogas liquid waste and the incubation time provides a significant influence (P |
