Abstract

The success of livestock business is influenced by the feeding cost which will affect production costs, Therefore, it is needed to find an alternative feeds which has high quality content with relatively low prices. Coconut dregs can be used as an alternative to livestock feeds, but it has high fiber content, so it has low digestibility. It is necessary to conduct a processing of coconut dregs by using fermentation with fiber degradating bacteria. The purpose of this research was to determine fiber content changes (NDF, ADF, and hemicellulose) in coconut dregs after experiencing fermentation process using fiber degradating bacteria from PLIEK U. The method used complete random factorial which was designed with two different factors and three replications. The results of analysis of NDF, ADF and hemicellulose showed that there were interactions on both factors, the highest fiber content (NDF, ADF, and hemicellulose) is on the interaction of P1W1 (1% and 3 days), and the lowest fiber content (NDF, ADF, and hemicellulose) was on the interaction of P3W3 (5% and 9 days). It was concluded that the fermentation of coconut dregs using bacteria from PLIEK U could degrade the fiber content of coconut dregs, the more bacteria given and the longer the incubation time, so the fiber content (NDF, ADF, and hemicellulose) more decrease, and the best fermentation treatment was found in P3W3 interactions that was fermentation with 5% inoculum and 9 days incubation.

Abstract

The need for animal feed in Pangururan District, Samosir Regency is very lacking, and livestock waste is also a problem in the community environment, so the utilization of EM4 goat's urine waste is expected to increase the growth of Indigofera (Indigofera zollingeriana) and Turi (Sesbania grandiflora) legumes in appropriate doses. . This research was conducted in Pangururan Subdistrict, Samosir Regency, North Sumatra from April to August 2018. The research design used in this research was factorial randomized block design (RBD) which was divided into 2 treatment groups and 3 replications. The first factor is the type of plant (L), L1 = Indigofera zollingeriana and L2 = Sesbania grandiflora and the second factor is the dose of fertilization (P), P0 = without fertilization (Control), P1 = 200 ml / polybag, P2 = 250 ml / polybag, P3 = 300 ml / polybag, and P4 = 350 ml / polybag). Parameters observed were plant height, number of stalks, number of leaves, and stem diameter. The results showed that respons of liquid organic fertilizer of goat urine fermented by EM4 with various doses of fertilization had a significant effect on the parameters of the study, namely plant height, number of stalks, number of leaves, and stem diameter. The conclusion of this study is that fertilization with a dose of 200 ml / polybag gives optimal results in the growth of Indigofera (Indigofera zollingeriana) and Turi (Sesbania grandiflora) legumes.
