Abstract

Abstract The aim of the research is looking for probiotic bacteria strategy for depresing the growth of patogenic bacteria in digestion of grouper fish. Some of anti bacteria can be produced by bacteria, such as protease, bacteriocia (germicidine, pyrocydia, circulin), amilase lipase, and lyzozym. In this case, Bacillus sp. is chosen because it can produce antibacteria againts Vibrio sp. and probiotic multifactor effect, that is enzyme production and competition of nutrient and space.

Abstract

Abstract Utilization of fish waste as an alternative feed ingredient in the effort to increase the availability of raw materials making up rations. Banana skin is one that has the potential of agricultural waste into alternative feed ingredients, but the nutritional value contained in the banana peel is still low so we need to attempt to improve nutritional content, one of which is fermentation method using Trichoderma viride and Bacillus subtilis in order to improve crude protein and lower content of crude fiber on a banana peel. This study aims to determine the influence of Trichoderma viride on crude protein and crude fiber are fermented banana skin, know the effect of Bacillus subtilis on crude protein and crude fiber are fermented banana skin and know the effect of interaction of Trichoderma viride and Bacillus subtilis of crude protein and fiber fermented banana skin rough. This research method is to experiment with Completely Randomized Design (CRD) as a factorial experimental design. The treatments used consisted of two factors, namely the effect of Trichoderma viride (factor A) and Bacillus subtilis (factor B). Factor A consisted of three dose levels: 0%, 3% and 6%, while factor B consists of three levels ie dose of 0%, 4% and 8%. Each treatment combination was replicated 3 times. The results showed that the use of Trichoderma viride and Bacillus subtilis in fermentation processes plantain skin showed significant differences on crude protein and crude fiber on dry matter (p<0.05).

Abstract

Abstract Water hyacinth (Eichornia crassipes) is a one of the feed materials from the green plants a potential. Howefer, the water hyacinth are low of protein and high fiber contents. Therefore, there should be efforts intentionally done to increase the leaf protein. One the ways to raise water hyacinth nutrient is performing biologically fermentation by using microbes. The Kombucha organism is a symbiotic colony of yeast's and bacteria that composed by strong membrane that covers gelatinous mass. Kombucha microorganism is living together with permeate the tea drink. The objective of this research is to know the effect of Kombucha to increased crude protein and decreased crude fiber contents in water hyacinth fermentation. The advantage of the research is to provide information regarding a Kombucha dosage which is required to enhance crude protein and reduce crude fiber content on water hyacinth fermentation. The research used water hyacinth as substrate and Kombucha as fermentor. Kombucha dosaged used here were P0 (0%), P1 (7,5%), P2 (15%) and P3 (22,5%). The fermentation took place 7 days and then proceeded with proximate analysis. Variables observed consisted of crude protein and crude fiber contents after being fermented using Kombucha. The result showed that Kombucha that was used for fermenting water hyacinth, could increase the crude protein content from 13,3040 % (P0) to 15,9972% (P3) and not significantly reduce the crude fiber. The Kombucha dosage at 7,5% (P1) was most effective for fermenting the water hyacinth.
