Abstract

In vitro studies were exploring eleutherine (Eleutherine americana) potential to be used as feed additive for poultry.  The eleutherine bulbs were extracted using four different organic solvents: methanol, ethyl acetate, diethyl ether and hexane.  The crude extracts were analyzed for their bioactive compounds, tested for anioxidant and antibacterial activity and tested for growth of non-pathogen bacteria. The results indicated that bioactives are indentified:phenol and tannin. Average of antioxidant activity were 33.74, 20.36, 15.14 and 1.98 ppm AEAC  for methanol, ethylacetate, diethylether and hexane, respectively. Furthermore, average of inhibition growth for  pathogen bacteria of Escherichia coli was 5.94, 4.75, 4.56 and 4.44  mm  for  methanol, ethylacetate, diethylether and hexane, respectively, while inhibition for  Staphylococcus aureus was 5.37, 6.50, 5.37 and 5.18  mm for  methanol, ethylacetate, diethylether and hexane, respectively. The extracts also have ability to enhance the gorwth of non-pathogen bacteria Lactobacillus acidophilus. Average of bacteria growth improvement was 21.12, 28.57, 28.16 and 19.59 NTU for methanol, ethylacetate, diethylether and hexane, respectively. The presence of antioxidant and antibacterial activity and growth enhancer activity could be attributed to the bioactive and non digested carbohydrate content of the bulbs extracts.  Therefore, it  could be concluded that the bulbs of eleutherine extract is potential source for “feed additive” as phytobiotics as well as prebiotics.Key words: Eleutherine, Extract, Bioactive, Phytobiotics, Prebiotics

Abstract

Government program that sets seaweed and results olahanya as commodity resulted in an increase in the amount of waste from processing into carrageenan seaweed cause environmental pollution. By him that, has done research on the nutritional evaluation of the waste and the efforts to improve the nutritional value of the waste that can be used as feed. This study uses bioconversion technology and using Rhizopus oligosporus as an inoculant. The study was conducted in two phases, namely the early stages of an evaluation study of the nutritional value of waste carrageenan and test its ability to grow on medium Rhizopus oligosporus waste. Furthermore, the implementation of the waste carrageenan bioconversion using Rhizopus oligosporus on some level in the medium (w/w). Preliminary results demonstrate that the solid waste seaweed had higher levels of crude protein 2.43%, fat 0.52%, ash content 4.07%, carbohydrates 7.25%, crude fiber 2.48%, 85.73% water, cellulose 23.29% and hemicellulose 16.51%. Furthermore Showed that Rhizopus oligosporus can grow well on media without the addition of carrageenan waste Nutrients. Bioconversion can improve the nutrient content of solid waste seaweed. Bioconversion of waste produced has a moisture content between 73.91 to 75.97%, protein content between 13.27 to 16.78%, fat content between 0.20 to 0,25%, ash content between 18.15 to 20.60%, a pH value between 6.56 to 7.35 while the crude fiber content Obtained between 13.45 to 20.37%. Based on the series of this study, it can be concluded that the solid waste Eucheuma cottonii seaweed can be used as a growing medium of Rhizopus oligosporus and can improve the nutritional content of seaweed waste. Use of inoculum in the medium waste carrageenan is possible until the level of 15% (w/w).   Key words: Bioconversion, byproducts, seaweed processing, solid waste.

Abstract

The purpose of this study was to determine the nutrient content of the bioconverted palm oil sludge using Rhizopusoligosporus so that it is suitable as functional feed. The used materials were oil palm mud flour and Rhizopusoligosporus fungus. The research design used a factorial completely randomized design with 8 treatments and 3 replications. The treatment consisted of two factors, the first factor was 4 concentrations, namely (0%, 5%, 10% and 15%) and two fermentation times, namely (60 and 96 hours). All treatments were analyzed for nutrient content including dry matter content (BK), crude protein (PK) and crude fiber (SK) fermented palm sludge. The results of the analysis of variety showed that the treatment had a very significant effect (P <0.01) on the content of BK, PK, SK and there was an interaction between the concentration of fungi and fermentation time on SK. The highest dry matter content for BK was obtained in W2K15 treatment (83.24%), PK on W2K15 (18.44%), and SK on W2K15 (24.00%).

Abstract

The purpose of this study was to determine the effect of the interaction between the concentration and time of the Neurospora sp. fungus on palm oil fermentation on the dry matter, crude protein and crude fiber content. This study used a completely randomized design (CRD) with a 3x3 factorial pattern, each treatment was repeated 2 times. The first factor was the concentration level of the fungus (0%, 5%, 10%) and the second factor was the fermentation time (48, 72, and 96 hours). The results of the analysis of variance showed that the interaction treatment between the concentration level of Neurospora sp. And the fermentation time of oil palm sludge had a very significant effect (P <0.01) on the dry matter and crude protein content, while the crude fiber content had no significant effect (P> 0.05). ). Independently, the concentration level and time significantly affected the dry matter content, crude protein and crude fiber. The highest value of dry matter was obtained at a combination of 72 hours and a concentration of 10% (W3K10% = 66.323%) and for crude protein, namely 96 hours and a concentration of 10% (W3K10% = 21.430%), while in crude fiber there was a decrease in each time or concentration.
