Effect of Urea Usage Rate on Ammoniation of Banana Bunch Waste Pulp on Dry Matter Digestibility Dry Matter, Organic Matter Digestibility, Ammonia, and Volatile Fatty Acids (In Vitro)
Abstract
Banana bunch waste is an agricultural waste that comes from banana bunches after the banana fruit is harvested. Banana bunch waste can be utilized, one of which is used as animal feed. This study aims to determine the effect of the level of urea use on ammoniation of banana bunch waste pulp on KcBK, KcBO, ammonia, and volatile fatty acids (in vitro). The research was conducted on January 05 - February 05, 2025, at the Laboratory of Ruminant Animal Nutrition and Animal Feed Chemistry, Faculty of Animal Science, Padjadjaran University, Jatinangor District, Sumedang Regency, West Java. The method used in this research is an experimental method using the Completely Randomized Design (CRD) method with 4 treatments and 5 replicates. The treatments consisted of the level of urea addition to ammoniation as P0 (0%), P1 (2%), P2 (4%), and P3 (6%). Data processing used analysis of variance and Duncan's test. The results showed that the treatment had a significant effect (P<0.05) on KcBK, KcBO, ammonia, and volatile fatty acids. The highest value was obtained in P3 treatment with 62.15% KcBK, 66.60% KcBO, and 168.24 mM of volatile fatty acids. From the results of the study, it can be concluded that the processing of banana bunch waste pulp with the ammoniation technique is best using urea as much as 6%.
