Ditambahkan oleh Kawamoto et al. (2001) bahwa kandungan serat kasar pelepah sawit mencapai 70%, sedangkan kandungan karbohidrat terlarut dan protein kasar masing-masing hanya 20% dan 7% (Dahlan, 2000). Kandungan lignin pelepah sawit mencapai 20% dari biomassa kering, sehingga merupakan pembatas utama dalam penggunaan pelepah sawit sebagai pakan ternak (Rahman et al., 2011). Pemanfaatan pelepah sawit sebagai bahan pakan ternak ruminansia perlu adanya treatment terlebih dahulu guna menurunkan kandungan li...

This study aims to determine the effect of some types of manure on growth and production of elephant grass (Pennisetum purpureum) cv. Taiwan. The expected results of this research can determine which is the type of manure suitable for the area of the former coal mines that have acid soils (marginal lands). This research using Complete Random Design with four treatments and six replications. The treatment is different source of manure which is control, cow manure, goat manure, and chicken manure. The parameters observed were plant growth including plant height, leaf width, leaf length, fresh weight production, and dry weight production.

Sugarcane tops and tithonia are alternative forages that can be used as an energy source and protein source in ruminants, but are constrained by the presence of lignin and anti nutrients. For this reason, a study was conducted to determine the effect of a combination of fermented sugarcane tops and fermented tithonia on the digestion of the fiber fraction(NDF, ADF, cellulose, and hemicellulose).The research design used a randomized block design (RBD) with 4 treatments, namely A (100% fermented sugarcane tops and 0% fermented tithonia), B (75% fermented sugarcane tops and 25% fermented tithonia), C (50% fermented sugarcane tops and 50% fermented tithonia), D (25% fermented sugarcane tops and 75% fermented tithonia) with 5 replications. Effect of treatment on parameters tested using analysis of variance and continued with Duncan's Multiple Range Test (DMRT) if there are differences between treatments. The results of experiments showed that treatments gave a very significant difference (P 0.01) to the in-vitro digestibility of fiber fraction (NDF, ADF, cellulose, and hemicellulose). From the results of the study, it can be concluded that the treatment C (50% sugarcane tops fermentation and 50% fermented tithonia) gives the best results on the in-vitro digestibility of fiber fraction NDF (78,13%), ADF (76,76%), cellulose (80,81%) and hemicellulose (81,11 %).
