Abstract

Chicken is one of the animal protein sources utilized to fulfill humans nutritional needs. Chicken is prone to be damaged and susceptible to be contaminated by pathogenic bacterial because chicken contains high nutrition. Ground meat is one of the livestock food production processed by meat-cutting and frequently sold in supermarkets. This research aims to seek the quality of microbial in chicken sold in supermarkets located in Jatinangor region. Specifically, this study attempts to ascertain the amount of bacterial and Staphylococcus aureus contained in chicken. The sampling method is carried out by simple random sampling in which the chickens are obtained from two different supermarkets in Jatinangor region. Furthermore, the calculation is carried out by using Total Plate Count (TPC) and the result is analyzed statistically by the descriptive method. The result shows that the average number of bacteria in Supermarket A is 5,43 x 10⁷ CFU/g, while in Supermarket B is 4,64 x 10⁷ CFU/g. Correspondingly, the amount of Staphylococcus aureus in Supermarket A is 7,2 x 10⁴ CFU/g and in Supermarket B is  2,9 x 10⁴ CFU/g. The number of bacterial and Staphylococcus aureus in ground chicken in both supermarkets exceeds the maximum number of microbial contamination limitations that have been determined by SNI in 2009 No.7388 which are 1 x 10⁶ CFU/g and 1 x 10 ² CFU/g.

Abstract

Processed cheese is a natural cheese that has undergone further processing to produce a more homogeneous texture. Bromelain enzyme derived from pineapple fruit which was used as a coagulant. Emulsifier in the form of monosodium phosphate (NaH2PO4) was used as an emulsifier. This study was aimed to determine the effect of the NaH2PO4 addition on moisture content, yield, and acceptability of processed cheese with pineapple juice coagulant. This research was conducted by experimental method using a completely randomized design with a significance level of 5% for 3 treatment concentrations (P1=2%, P2-3%, and P3=4%). Each treatment was repeated 6 times. If there was a difference, Duncan’s further test is carried out. Acceptability data was tested using Kruskal-Wallis, if there was a difference, the Mann-Whitney further test was carried out. The results showed that the use of NaH2PO4 with concentration of P1 (2%), P2 (3%) and P3 (4%) had no effect on moisture content and yield. The best acceptability value was found in P2 (3%) with a numerical scale for the best taste, namely 3.67 (slightly like-like), color 3.73 (slightly like-like), aroma 4.27 (like-like very much), texture 3.60 (slightly like-like), and the total acceptance is 3.53 (slightly like-like).

Abstract

Utilization of rabbit skin as a food product has not been carried out optimally, it is not in line with the increasing production of meat. The high protein content makes rabbit skin potential to be used as gelatin. Gelatin is a protein-derived compound that has translucent, colorless, and tasteless properties. This makes gelatin suitable as a raw material for the manufacture of edible films. Edible film is a packaging layer for edible food products. The added glycerol plasticizer can affect the characteristics. This study aims to determine the right concentration to obtain moisture content, film, and water vapor transmission rate of edible film from rabbit skin gelatin. The method used is an experimental method with a completely randomized design (CRD) with 4 treatments consisting of glycerol concentrations of 5%, 10%, 15%, and 20%. Each treatment was repeated 5 times with observed moisture content, thickness, and water vapor transmission rate. The statistical test used ANOVA’s test, then Duncan's advanced test at the 5% level. The results of statistical analysis showed that the different of concentrations glycerol had a significant effect (P<0,05) on the moisture content, thickness, and water vapor transmission rate of edible film. The best film was produced in 10% glycerol (P2) with 8,8% moisture content, 0,15 mm thickness, and 41,9 g/m2.24hours water vapor transmission.

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

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.
