Abstract

Sliced cheese merupakan keju yang dipotong menjadi irisan tipis dengan ukuran yang seragam. Keju terbentuk dari gumpalan akibat koagulasi protein susu oleh enzim rennet. Rennet memiliki harga yang relatif mahal sehingga dibutuhkan alternatif yang dapat digunakan dalam proses koagulasi. Salah satu alternatifnya adalah enzim papain dari getah pepaya. Namun, penggunaan papain tersebut dapat berdampak pada tekstur keju yang mengeras sehingga ditambahkan minyak jagung untuk memperbaiki tekstur dari keju tersebut karena mengandung asam lemak tak jenuh yang tinggi. Penelitian ini bertujuan untuk mengetahui konsentrasi minyak jagung yang akan menghasilkan pH, kekompakan (firmness), dan keempukan terbaik. Penelitian dilaksanakan pada bulan Januari-Maret 2024 di Laboratorium Teknologi Pengolahan Produk Peternakan dan Laboratorium Riset dan Pengujian Bioteknologi, Fakultas Peternakan, Universitas Padjadjaran. Penelitian ini dilakukan secara eksperimental dengan Rancangan Acak Lengkap (RAL) menggunakan empat perlakuan dan lima ulangan dengan persentase minyak jagung yang terdiri dari P0 (tanpa pemberian minyak jagung), P1 (5%), P2 (10%), dan P3 (15%). Data dianalisis menggunakan analisis sidik ragam dan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa penambahan minyak jagung pada pembuatan sliced cheese memberikan pengaruh yang sama terhadap nilai pH dan keempukan. Namun, menurunkan nilai kekompakan (firmness). Penambahan minyak jagung dengan konsentrasi 5% merupakan konsentrasi terbaik karena menghasilkan nilai kekompakan (firmness) yang tinggi.

Abstract

Processed cheese is a cheese product made from one or more types of fresh cheese that undergoes further processing to extend shelf life and develop new cheese varieties. Corn oil contains saturated fatty acids, unsaturated fatty acids, and phenolic compounds that can inhibit microbial growth. This study aims to determine the effect of corn oil addition in making sliced cheese with dried papaya latex coagulant on the total of yeast, bacteria, and mold. This study was conducted experimentally using a Completely Randomized Design (CRD), consisting of 4 treatments of corn oil concentration (P0 = 0%, P1 = 5%, P2 = 10%, and P3 = 15%), where each treatment was repeated as many as 5 replicates. Data on the total of yeast, bacteria, and mold were analyzed using the variance test and Duncan's further test. The results showed that the addition of corn oil at 15% in the manufacture of processed cheese (sliced cheese) had a significantly lower effect on the total yeast count of 0.59×103 cfu/g and no significant effect on the total bacteria and mold.

Lactic acid bacteria are group of bacteria which ferment food carbohydrates and produce lactic acid as the main product of fermentation. This study aimed to determine the specific growth rate of lactic acid bacteria (Streptococcus thermophilus FNCC 0040 (ST), Lactobacillus bulgaricus FNCC 0041 (LB), Lactobacillus acidophilus FNCC 0051 (LA), Lactobacillus casei ALG.2.12 (LC ALG 2.12), Bifidobacterium ATCC 12746 (BF) as a preliminary study for the production of flavored yogurt. In this study, lactic acid bacteria was culture in two different medium, deMan Rogosa Sharpe (MRS) Broth and deMan Rogosa Sharpe (MRS) Broth with red bean extract. Optical density, lactic acid biomass and pH was measured during fermentation processed. The results showed that the addition of red bean extract increased the specific growth rate of lactic acid bacterial isolates and lowering the pH of the medium so that the use of red bean extract can be used as a prebiotic which can increase the growth of lactic acid bacteria. The highest specific growth rate was Bifidobacterium in MRS Broth medium with red bean extract.

Abstract

Escherichia coli is commensal bacteria in the intestinal of broiler chickens with low virulence. However, mostly pathogenic and cause colibacillosis illness. Inappropriate use of antibiotics in broiler chickens has been widely reported. This research aims to determine the presence of E. coli contamination in the poultry environment and determine the levels of antibiotics resistance of erythromycin, doxycycline, oxytetracycline and neomycin. The research was carried out through isolation and identification of E. coli using EMB media, Gram staining, and biochemical tests. Then, an antibiotic resistance test was carried out using by Kirby-Bauer method. From a total of 10 samples (3 coops), 7 (70%) were positive for E. coli. The positive of 7 which for E. coli, 43% of the isolates came from fresh feces obtained from coops 1, 2, and 3; 43% of the isolates came from litter from coops 1, 2, and 3; and 14% of isolates from soil outside the coop 3. The antibiotic resistance results by Kirby-Bauer method showed that E. coli was 100% resistant to erythromycin, 100% to neomycin, 66.7% to doxycycline, and 66.7% to oxytetracycline throughout isolates from feces and litter. Other results showed that isolates from soil outside coop 3 showed resistance to all antibiotics. Taken together, we concluded the E. coli has been contamination which is proven by antibiotic resistance.

Abstract

This research examined the effect of different densities on carcass weight, carcass parts, and carcass percentage. The material used in this research was 200 broiler chickens aged three weeks, reared for 14 days until they were 35 days old. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments and four replications. If the analysis of variance showed an effect of treatment (P<0,05), then Duncan's Multiple Range Test was carried out to determine the effect between treatments. The treatments used were P1 = density of 13 birds/m², P2 = density of 14 birds/m², P3 = density of 15 birds/m², P4 = density of 16 birds/m², and P5 = density of 17 birds/m². The study found that density had no significant effect (P>0,05) on the carcass weight, carcass parts, and carcass percentage. Based on the research results, it can be concluded that a density of 16 birds/m² for broiler chickens kept in closed houses still provides good production performance and meat quality.

Abstract

Cheese is a food produced through the process of coagulation and separation of curd and whey. Processed cheese has become a favorite of many people due to its unique and practical characteristics. The complex process of cheese making involves the use of rennet enzyme as one of the key components. Noni contains a significant amount of protease enzyme that can be used as a substitute for rennet. This study aimed to determine the effect of mung bean starch addition on yield, color, and firmness of processed cheese coagulated with noni fruit juice. This study used a Completely Randomized Design with four treatments of mung bean starch concentration (P0=0%, P1=2,5%, P2=5%, P3=7,5%) and five replication. Analysis of variance was carried out after the data was obtained and continued with Duncan's Multiple Range test. The results showed that the addition of mung bean starch did not give a significant effect on color, but gave a significant effect on yield and firmness. The use of 7,5% mung bean starch concentration produced the best processed cheese with a yield of 70,16%, color including L* of 58,03, a* of -0,22, b* of 18,48, and firmness of 67,73N.
