Abstract

One way to overcome the problems of banana skin waste is to use it as raw material for the manufacture of nata through fermentation by the bacteria Acetobacter xylinum. The purpose of this experiment is to study the effect of the use of some waste of various banana skins on the physicochemical properties of nata produced. The design of experiments was conducted using Completely Randomized Design divided into four treatments, namely KP1  use of kepok kuning banana skin, KP2 use of raja banana skin, KP3 use ambon banana skin and KP4 use of kluthuk banana skin. Each treatment was conducted with three replications. Medium starter and fermentation made use of medium Hassids and Barker which had been modified with N sources of ZA, and vinegar table. Testing the physicochemical properties of nata produced was done through the measurements of the thickness, weight, yield, texture, and water content. The results showed that differences in the types of banana skin waste had an effect on the physicochemical properties of nata produced. The use of ambon banana skin produced the best results on the physicochemical properties of nata.

Abstract

Bulbs of great varieties can be used as raw materials for alcoholic fermentation. The purpose of this experiment is to study the effect of different time of alcoholic fermentation on the quality of solid brem produced. This research was conducted by using completely randomized design with three replications. The samples comprised 4 treatments of fermentation time, including 2 (two) days, four (4) days, six (6 ) days and 8 ( eight ) days. The solid brem quality was determined by measuring the alcohol content, yield, pH and moisture content. The results showed that all four treatments of fermentation affected the quality of the solid brem, which includes analysis of alcohol content, solid brem yield, and pH. While, the results of analysis of the water content measurements showed no significant difference. The results of fermentation with longer time showed an increase in alcohol content and yield, while the level of acidity ( pH ) decreased.

Abstract

Trichoderma mass production requires the appropriate media, so the first step is necessary to identify the substrates which are appropriate, inexpensive, stable, and easily available. The purpose of this study was to evaluate the effect of agricultural waste corn straw, rice straw and bagasse against fungal radial growth activity of Trichodema viride. The study was conducted with one control and three treatments. The control was without the addition of agriculture waste; the three treatments were with the addition of corn straw powder substrate, rice straw powder substrate, and bagasse powder substrate. The observation of the research parameters included the macroscopic and microscopic observation of the fungus Trichoderma viride isolate and the measurement of growth rate during the incubation period, namely within 24 to 110 hours. The result of the measurement of the activity of radial growth of Trichoderma viride showed that the addition of the substrate bagasse was the highest in which the diameter was 74.96 mm, while the addition of corn straw substrate had the lowest in which the diameter was 32.69 mm. The highest rate of radial growth of 20.11 mm/day was produced by the addition of substrate bagasse, while the lowest rate, namely 11.42 mm/day, was the result of the addition of corn straw.
