Abstract

Cattle farming is one of the livestock business commodities in Indonesia. In the production process, cattle farms produce waste in the form of feces and leftover feed which can be processed in such a way through a decomposition process into organic fertilizer. The rate of the decomposition process is influenced by the existing decomposer microbes. One of the microbes needed in the decomposition process is cellulolytic bacteria. The research was conducted to obtain potential cellulolytic bacterial isolates from the compost which can then be used as a starter in the decomposition process. This research was conducted experimentally with the stages of research including isolation of bacteria from decomposers, the isolates obtained were then reviewed on Nutrient Agar media to produce uniform colonies. Furthermore, screening was carried out to obtain cellulolytic bacteria using NA media added with 1% CMC (Carboxymethyl Cellulose). Based on the results of the study, obtained 7 bacterial isolates that have various cellulolytic indices. The best cellulolytic index was produced by isolates NC-12, NC-17, and NC-16.

Abstract

The increase in the number of consumers of coffee drinks encourages variations in fermented beverage products that use coffee as an additive, one of which is yogurt. The addition of Arabica coffee which contains polyphenols are thought to stimulate growth and increase the activity of lactic acid bacteria. The purpose of this study was to determine the right concentration in the manufacture of Arabica coffee yogurt so as to produce good characteristics and fit into the yogurt standard SNI 01-2981-2009 and can increase the growth activity of lactic acid bacteria. The research method used was thedescriptive experimental method with two replications and 4 treatments of added coffee concentration variations (0%, 1%, 2%, and 3%). The addition of 1% Arabica coffee to yogurt was the best treatment with the characteristics of total titratable acidity of 1.10% and total lactic acid bacteria of 8.94 Log CFU/g which has met the requirements of SNI 01-2981-2009, pH 4.15, and total polyphenols of 1.54 mgGAE/100 mL.

Abstract

Phytoremediation is an effort to restore polluted land by absorbing, degrading, removing, stabilizing, or transforming pollutants using hyperaccumulator plants. Mexican Sword plants in phytoremediation are used as hyperaccumulators that can reduce heavy metal content by rhizofiltration mechanism. This study aims to determine the effect of mexican sword plant quantity on chromium concentration, pH value, and Dissolved Oxygen (DO). The research was conducted using an experimental method using a Completely Randomized Design (CRD), with 4 treatments, P0 = 0 mexican sword plants, P1 = 4 mexican sword plants, P3 = 6 mexican sword plants, P4 = 8 mexican sword plants. Repetition was carried out five times for each treatment. The data obtained were analyzed statistically by Analysis of Variance at = 5% and if there is a significant difference, further tests will be carried out using the Tukey test. The results showed that there was a significant difference (P<0.05) for each quantity of mexican sword plants concerning chromium concentration, pH value, and Dissolved Oxygen (DO). The best treatment results were shown by the quantity of 6 individuals (P2) with a Chromium concentration of 16.87 mg/L, a pH value of 8.45, and a DO of 1.3%.

Abstract

Andaliman contains active compounds including flavonoids, glycosides, tannins, and has a unique taste, which is a spicy blend with the lemon flavor can be used as a natural preservative to reduce the number of bacteria, prolong the time of rot and the acceptability of meat. The aim of the study was to determine the effect of using the different concentrations of andaliman fruit extract and to determine the best concentration that could reduce the total number of bacteria, delay the onset of spoilage and maintain acceptability. The experimental study used a completely randomized design, with four concentrations of andaliman fruit extract; 0% (P1), 0.25% (P2), 0.50% (P3), and 0.75% (P4). Analysis of variance was used to determine the effect of the andaliman extract concentration on total plate count and the onset of spoilage. The differences between the treatments were observed using Duncan’s multiple range test. The acceptability was analyzed using Kruskal-Wallis’s test and Mann-Whitney’s test. The results showed that the marination using andaliman extract at 0.75% gave the best results in terms of total plate count of 7,9 x 106 cfu/g, the onset of spoilage at 717 minutes and acceptability by the panelists.

Abstract

Gelatine is a product produced from collagen hydrolysis.  Solvents that can be use in the manufacture of gelatin are acidic and basic solutions.  The acid used in this experiment is hydrochloric acid (HCl). The quality factor of gelatine can be determined from the amount of yield, moisture content, and ash content. The quality of gelatine also depends on the concentration of hydrochloric acid solution.  This experiment aims to determine the effect of HCl concentration on yield, moisture content, and ash content of gelatine from duck feet, to find the concentration of HCl that can produce the best quality of gelatine from duck feet, and to find the form of tendency between treatments of HCl concentration on yield, moisture content and ash content of gelatine from duck feet. The experiment was conducted experimentally using Completely Randomized Design (CRD).  The treatments used were HCl concentration P1 (4%), P2 (6%), and P3 (8%), with six times repetation so that there were 18 experimental units.  The results showed that the use of hydrochloric acid 6% can gave the best quality of gelatine from duck feet with 8,04% yield, 5,99% moisture content, and 3,98% ash content.
