Abstract

Concentrated layer poultry farm produce manure that accumulate in one place and have the potential to pollute the environment. Manure is an organic material that is not yet stable and contains both pathogenic and non-pathogenic microbes, therefore it needs to be handled so that the organic waste material decomposes into nutrients that are stable and safe for the environment. Manure can be processed by vermicomposting, one of the requirements for vermicomposting is a C/N ratio, manure has a low C/N ratio, to increase the substrate C/N ratio, leaf litter can be added. The purpose of the study is to know the effect of C/N ratio in vermicomposting of chicken excrement mixture and foliage on the temperature changes, total number of bacteria and coliform and on the C/N balance that produces the lowest total coliform. Research was conducted using a complete randomized design consists of 3 treatment with different ratio C/N, P1(C/N 25), P2(C/N30), P3(C/N 35) which is repeated 6 times, Data were analyzed with the variance and continued with Duncan Test. The results showed that the C/N ratio balance in vermicomposting of the mixture of manure and leaf litter had a significant effect on the total number of bacteria, but had no significant effect on total coliform. The balance of C/N ratio of 30 resulted in the highest total bacterial count and the lowest coliform in the decomposition process of 60.67 x 1011 cfu/g and 12,86 MPN/mL.

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

Set yogurt is a yogurt product that has a characteristic thick texture containing dry ingredients about 20% derived from fresh milk and skims milk. The addition of Red Dragon Fruit Pulp to yogurt is used as a good substrate with simple sugar components to stimulate the growth of lactic acid bacteria, pH value, and total acid set yogurt. The method used in this study is a Completely Randomized Design (CRD) in various concentrations of each treatment were 0% (P0), 5% (P1), 10% (P2), 15% (P3), and five replications. The obtained data were statistically analyzed by ANOVA at = 5% and if there were significant differences, further tests will be carried out using the Duncan Multiple Region Tests (DMRT). The results showed significant differences (p<0,05) in various concentrations of Red Dragon Fruit Pulp on total acid bacteria, pH value, and total acid. The red dragon fruit pulp concentration of 15% added to the milk resulted in the best set yoghurt with a total lactic acid bacteria of 9,52 x 108 CFU/ml, pH value of 4,19, and total acidity of 1,12%.

Abstract

Management of layer excreta and leaf litter can be done by using the vermicomposting method that utilizes the activity of earthworms and microorganisms. The activity of earthworms and microorganisms will reduce the C/N ratio and shrinkage in vermicomposting. This study aimed to determine the effect of a mixture of layer excreta and leaf litter on vermicomposting to the C/N ratio and shrinkage in vermicompost. This study used an experimental method with a completely randomized design (CRD), with three C/N ratio treatments, namely T1 (25), T2 (30), and T3 (35) with six replications. Further analysis using Duncan's multiple distance test. The process begins with initial decomposition for 14 days, followed by vermicomposting for 14 days. The results showed that the C/N ratio during vermicomposting reached 17.84 – 33.23 with shrinkage ranging from 15.00% - 33.50%.
