Abstract

This study aims to evaluate the effect of different levels of putak starch (Corypha utan Lamk) in market vegetable waste silage on fermentability in vitro, particularly on total VFA (Volatile Fatty Acids) concentration, NH3 (ammonia), and pH. The research was conducted from April to June 2025 at the Animal Feed Chemistry Laboratory, Faculty of Animal Husbandry, Marine and Fisheries, Nusa Cendana University. The study used a completely randomized design (CRD) with four treatments and four replicates. The treatments were P0 (without putak starch), P1 (10% putak starch), P2 (20% putak starch), and P3 (30% putak starch). The variables observed were total VFA, NH3, and pH. The results showed that the addition of putak starch had a significant effect (P<0.05) on increasing total VFA concentration, highly significant effect (P<0.01) on decreasing NH3 concentration, and significant effect (P<0.05) on pH. The highest total VFA was found in P3 (146.201 mM), while the lowest NH3 was also found in P3 (6.780 mM). The pH values ranged from 6.625 to 6.850, which were still within the optimal range for rumen fermentation (6.0–7.0). It was concluded that the addition of putak starch up to 30% could improve the fermentation quality of market vegetable waste silage, with the best treatment being 20% putak starch.

Abstract

This study aims to evaluate the effect of the use of pollard as an additive on the content of the silage fiber fraction of banana peel waste. The ingredients used are raw kepok banana peel and pollard as additives that are fermented for 28 days. The method used was an experimental method using a complete random design (CRD) consisting of 4 treatments and 4 replicates. The treatment is P0 = raw banana peel waste without pollard; P1 = raw banana peel waste + 10% pollard; P2 = raw banana peel waste + 20% pollard; P3 = raw banana peel waste + 30% pollard. The parameters measured are: NDF, ADF, Hemicellulose, Cellulose, and Lignin. Data analysis used variance analysis (ANOVA) to test the effect of treatment on parameters and followed by Duncan's follow-up test to get the best treatment. The results of statistical analysis showed a very significant influence (P<0.01) on the measured parameters. It was concluded that the use of Pollard by 30% as an additive in the manufacture of banana peel waste silage resulted in a decrease in the content of NDF, ADF, Cellulose and Lignin but increased the content of Hemicellulose.
