EVALUASI KANDUNGAN BAHAN KERING, BAHAN ORGANIK, DAN PROTEIN KASAR LIMBAH SERAI WANGI AMONIASI SEBAGAI BAHAN PAKAN TERNAK RUMINANSIA

This research aims to determine the dose of urea to increase the dry matter, organic matter, and crude protein content of citronella waste as a feed ingredient for ruminants. A factorial design in a 2×3 Completely Randomized Design (CRD) with 3 replications. Factor A (length incubation of 14 and 21 days) and Factor B (3%, 5%, 7% urea dose) were used in this study. The results of the statistics analysis showed that there was no interaction (P>0.05) between factor A and factor B on dry matter and organic matter content. There was an interaction (P<0.01) between factor A and factor B on crude protein content. The best results in this study were found in the length incubation treatment of 21 days at a urea dose of 7% with a dry matter content of 74.5, an organic matter content of 87.37%, and a crude protein content of 16.01%.
