Abstract

This study aims to test the activity of cellulase enzyme (CMCase) from indigenous bacteria "Bacillus Sp YLB1" as bioactivator of palm oil based feed. The treatment consists of various combinations of substart (feed), namely: P1 = 80% palm leaves + 10% palm kernel cake + 10% sludge; P2 = 60% palm leaves + 20% palm kernel cake + 20% sludge and P3 = 60% palm leaves + 30% palm kernel cake + 30% sludge. The parameters observed were cellulase enzyme activity (CMCase) on various combinations of palm oil waste and fermentation time. The results showed that cellulase enzyme (CMCase) production of Bacillus sp YLB1 bacteria during fermentation fluctuated ie 0.143 Units / ml; 0.372 Units / ml; 0.588 Units / ml; 1.013 Units / ml; 0.906 Units / ml; 1,065 Units / ml and 1,198 Units / ml.The activity of cellulase enzyme (CMCase) on substrate P1 (0.460 Unit / ml) is lower than P2 (0.897 Unit / ml) and P3 (0.908 Units / ml). From the results of this study can be concluded that cellulase enzyme activity indigenous bacteria Bacillus sp YLB1 influenced by the combination of substrate and fermentation time. The P3 substrate fermented with Bacillus sp YLB1 for 7 days gave a more optimal result than the other treatments.   Keywords: Cellulase enzyme, indigenous bacteria, substart (feed)

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

Coconut plants are common in Indonesia, which is the second largest copra producer in the world. Coconut dregs has never been used before, as result  it is one of large wastes in Indonesia. The main problems of coconut dregs were the content of crude fiber and crude fat which are high and low crude protein. Special attention was needed to improve the nutritional content by using fermentation technology. Fermentation was used in this study by using bacteria which had derived from the coconut plant itself called pliek u, isolate (YNH11). This study was conducted for 3 months starting from April to July 2018 at the Animal Production Laboratory and the Laboratory of Animal Food Nutrition Sciences Faculty of Agriculture, University of North Sumatra. This research was designed using a Completely Randomized Design (CRD) factorial pattern of 3 x 3, with 3 replications where remarked as factor 1 was the various levels of bacterial inoculum YNH11 from pliek u and factor 2 was the duration of fermentation (incubation). the parameters measured were water content, dry ingredient , crude protein, crude fiber, crude fat, and ash content using proximate analysis.The results showed that coconut pulp fermentation using bacterial origin of pliek u (isolate YNH11) with the level of inoculum administration and fermentation time had an effect on the measured parameters. it eventually increased water content and crude protein, meanwhile it decresed crude fiber, crude fat, dry ingredient, and ash content as well.
