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.

Highlights

Coconut plants (Cocos nucifera L.) are a type of palm plant that has multiple functions because almost all parts of the plant can be utilized
Based on duncan test there is increasing of moisture content seen from inocculum bacteria after fermentation, we can find the highest average in P3 from 11,38 % be 12,93 % or as big as 11,98
Based on duncan test there is decreasing of dry matter seen from inocculum bacteria after fermentation, we can find the highest average in P3 from 88,62 % be 86, 99 % or as big as 1,83 % and the lowest average is P1 from 88,62 % be 87,25 % or asa big as 1,54 %, and seen from fermentation time, we can find the highest average in W3 from 88,62% % be 86,99 % or as big as 1,83 % and the lowest average is W1 from 88,62 % be 87,62 % or asa big as 1,12 %

Summary

Introduction

Coconut plants (Cocos nucifera L.) are a type of palm plant that has multiple functions because almost all parts of the plant can be utilized. Coconut plantations in Indonesia reach 3,759,397 ha. Coconut pulp is usually only disposed of or given to other livestock without any process. The main problem of coconut pulp when used as feed ingredients is low crude protein content, crude fat and high crude fiber. Fermentation is a food processing technology with the help of decomposing microbes which in this study used bacterial isolates from pliek u, which are bacteria derived from coconut. Microbes derived from their own substrate have a progressive task in degrading the substrate [3]. The authors are interested in examining the ability of bacteria from pliek u as inoculants in coconut pulp fermentation to improve their quality and nutritional content
