Abstract

ABSTRAKTujuan penelitian ini adalah untuk mengetahui cemaran baku mutu air limbah Rumah Potong Hewan (RPH) Sapi dan Ayam di Kota Mataram. Semua hasil melebihi baku mutu kecuali nilai pH. Kandungan ALT rerata air limbah RPH sapi 284004 x 104 koloni/ml dan mengandung mikroba jenis E.coli dan Salmonella. Sedangkan air limbah RPH ayam ALT rerata 101596 x 105 koloni/ml dan mengandung kuman jenis E. coli, Pseudomonas aeruginosa dan Klebsiella pneumoniae. Tingginya kandungan BOD, COD, TSS, ammonia, pH, minyak dan lemak maupun cemaran mikroba diduga disebabkan tidak difungsikannya Instalasi Pengolahan Limbah (IPAL) pada RPH sapi dan tidak optimalnya fungsi IPAL di RPH ayam.Kata kunci: RPH sapi, RPH ayam, Baku mutu limbah RPH, Cemaran mikroba, kota Mataram yABSTRACTThe purpose of this study was to determine the contamination of waste water quality standard and microbiologic contamination ofcattle and chicken slaughterhousein Mataram city. TPC average content of waste water of cattle slaughterhouse was 284004 x 104 colonies/ ml, and contained microbial species of E. coli and Salmonella. However, the TPC avarange of wastewater of chicken slaughterhouse accounted for 101596 x 105 colonies/ml and contained microbial species of E. coli, Pseudomonas aeruginosa and Klebsiella pneumoniae. High content of BOD, COD, TSS, ammonia, pH, oil and fats as well as microbial contamination may relate to disfunctionality of Waste Water Treatment Installation (IPAL) in cattle slaughterhouse and too less optimum function of the IPAL in chicken slaughterhouse.Keywords: cattle slaughter house, chicken slaughter house, slaughterhouse waste quality standard, microbial contamination, Mataram cityCitation: Aini, A., Sriasih, M, dan Kisworo, D.

Abstract

The term "organoleptic testing" is synonymous with the more specific term "sensory evaluation". The objective of the study was to ascertain the impact of incorporating supplementary yellow corn in the formulation of broiler chicken nuggets on their sensory quality and cooking loss. The research method employed was of an experimental nature, utilising a Completely Randomised Design (CRD) with three distinct treatments: P0, representing the control, P1, which involved the incorporation of 25 g of yellow corn into a 100% nugget mixture (10%), P2, encompassing the addition of 37.5 g of yellow corn into a 100% nugget mixture (15%), and P3, comprising the inclusion of 50 g of yellow corn into a 100% nugget mixture (20%). Recent studies have demonstrated that the provision of yellow corn does not exert a significant influence on the sensory quality values and cooking losses of broiler chicken nuggets (p > 0.05). The cooking loss of P1 nuggets was found to be 0.019% lower than that of P2 nuggets (0.22%) and P3 nuggets (0.41%). The Duncan test demonstrated that there was a negligible difference between P1 and P2, and between P2 and P3. Furthermore, there was no significant difference between P2 and P3. The lowest cooking loss for chicken nuggets in the treatment with the addition of yellow corn was P1 0.019%. This shows that the higher the level of yellow corn added, the lower the cooking shrinkage. The lower the cooking shrinkage value, the better the product quality because there will be less nutritional loss, on the other hand, the higher the cooking shrinkage value, the lower the product quality. The findings showed that the provision of yellow corn did not have a significant effect on the sensory quality or cooking loss of broiler chicken nuggets.

Abstract

The utilization of natural polymer-based feeding films has emerged as an alternative to plastics and as a solution to the problem of environmental pollution. Concurrently, these films maintain the function of maintaining the shelf life, quality, and safety of food products. The objective of this study was to ascertain the effect of varying proportions of whey-chia seed combinations and types of plasticiser on the physicochemical characteristics of food films. The present study employed a completely randomised factorial design, comprising Factor A: whey-chia seed combination (A1 = 1:0.5; A2 = 1:0.75 and A3 = 1:1) and Factor B: type of plasticizer (B1 = sorbitol and B2 = polyethylene glycol/PEG). The interaction between the whey-chia seed combination and the type of plasticizer did not show a significant effect (P>0.05). However, the whey-chia seed combination itself had a significant impact (P<0.01) on film elongation and tensile strength. The utilisation of sorbitol as a plasticiser resulted in enhanced flexibility of the film, thereby rendering it more appropriate for utilisation in healthy and environmentally friendly food applications. The optimal treatment was determined to be a mixture of whey-chia seeds in a 1:1 ratio with sorbitol plasticizer, yielding an elongation at break of 74.23%, tensile strength of 3.997 MPa, and crude fibre content of 15.67%.

Abstract

Nugget ayam merupakan salah satu produk olahan daging yang semakin diminati oleh masyarakat karena kepraktisannya. Kualitas nugget dipengaruhi oleh beberapa faktor, termasuk aroma yang dapat meningkatkan daya tarik produk bagi konsumen. Penelitian ini bertujuan untuk mengoptimalkan produksi nugget ayam dengan menambahkan vanili sebagai bahan pemberi aroma dan mengukur pengaruhnya terhadap kesukaan konsumen. Menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan penambahan vanili (0,2%, 0,5%, dan 0,8%), hasil penelitian menunjukkan bahwa penambahan vanili tidak berpengaruh signifikan terhadap warna, aroma, dan tekstur nugget ayam. Namun, penambahan vanili pada kadar tinggi (0,8%) menghasilkan rasa pahit yang mengurangi tingkat kesukaan konsumen, meskipun juga menunjukkan susut masak yang lebih rendah, mengindikasikan kehilangan nutrisi yang lebih sedikit. Kesimpulannya, penggunaan vanili perlu dilakukan dengan takaran yang tepat untuk menghindari perubahan rasa yang tidak diinginkan, dan penelitian lebih lanjut diperlukan untuk mencari bahan pemberi aroma lain yang lebih efektif.

Abstract

Palopo is a traditional food typical of West Sumbawa, West Nusa Tenggara Province, made from pure buffalo milk with a characteristic soft texture with the addition of eggplant (Solanum virgianium L) in the coagulation process. The use of probiotics and microorganisms in the milk fermentation process is part of the development of milk-based functional foods. This study aims to determine the microbiological properties of Palopo added with lactic acid bacteria as a functional food to determine the role and impact of microorganisms on the quality of Palopo. LAB viability data were analyzed by analysis of variance (ANOVA) using SAS software. If the treatment had a significant effect, then we continued with Duncan's difference test. The results of analysis of variance showed significant differences in LAB viability in Palopo. The highest number of LAB was found in Palopo, added with Streptococcus thermophilus (ST), with a total of 10,172 Log CFU/ml. Based on Duncan's further test, there was no significant difference in LAB viability in ST against LB and LP. Palopo without the addition of LAB was found to have viable LAB with a total of 2, 623 Log CFU/ml. So that LAB is concluded to be able to significantly improve the quality of Palopo products.

Abstract

Edible film is a thin, edible film used as a food coating. The advantages of edible film include its biodegradability and its ability to maintain the quality and shelf life of the food product it covers. The objective of this study was to ascertain the impact of varying concentrations of sorbitol on the thickness, water vapor transmission rate, and microstructure of whey-chia seed edible film. The present study employed a Completely Randomized Design, comprising three distinct treatments, each with three replicates. The data obtained were analysed using Analysis of Variance, and if there were significant differences between treatments, these were followed by Duncan Multiple Range Test. The treatments incorporated the following: P1 (10% sorbitol), P2 (20% sorbitol), and P3 (30% sorbitol). The variables measured in this study were thickness, water vapor transmission rate and edible film microstructure. The findings demonstrated that the incorporation of sorbitol at varying concentrations elicited a highly significant effect (P<0.01) on the thickness of the edible film. However, the water vapor transmission rate test did not yield a significant difference (P>0.05). The mean thickness of the samples ranged from 0.0296 to 0.0303 mm, and the water vapor transmission rate ranged from 4.60 to 5.68 g/mm²/day. Microstructure analysis revealed that the incorporation of sorbitol enhanced the flexibility and uniformity of the distribution of the films at concentrations of 10% and 20%. However, at a concentration of 30%, the films exhibited increased rigidity and reduced flexibility. The utilization of a 20% sorbitol concentration was identified as the optimal treatment.

Abstract

Oyster mushrooms are a healthy alternative food source for reducing the fat content of sausages due to their low fat content. Chicken sausage is a processed meat product that typically contains meat, binders, and fillers. This study aimed to investigate the physical and microbiological properties of chicken sausage with varying concentrations of oyster mushrooms, which are added to improve its quality. The study employed a completely randomized design with three treatments. If a treatment showed a difference, the Duncan Multiple Range Test was conducted. The treatments consisted of J0: 0% oyster mushroom, J1: 1% oyster mushroom, and J2: 2% oyster mushroom. Statistically, the use of different concentrations of oyster mushrooms did not result in a significant difference (P>0.05) in the water binding capacity, breaking power, pH, and total plate count of chicken sausages. However, the addition of oyster mushroom concentrations can improve the physical and microbiological quality of the sausages. The addition of different concentrations of oyster mushroom to chicken meat sausage resulted in a water binding capacity of 39.28-46.12%, breaking strength of 0.4-0.5 kg/cm2, pH value of 6.46-6.56, and total plate count of 1.57-1.86 cfu/g. The treatment that yields the highest water binding capacity (45.06%), breaking power (0.04 kg/cm2), pH (6.56), and total plate count (1.57 cfu/g) is the addition of 1% oyster mushroom concentration. The concentration of oyster mushroom used in the preparation of chicken meat sausages should not exceed 1% of the total sausage mixture.

Abstract

The male Peking duck is a type of meat duck that has great potential to be developed as a producer of carcasses and primal carcass cuts. The research was carried out with the aim of finding out the best level of addition of pineapple peel fermented yeast (Saccharomyces cereviceae) culture to the percentage of carcasses and carcass primal cuts of male Peking ducks. The material used in this research was 240 male Peking ducks with an initial weight of 343.90 ± 0.90 g. The ration used contains 16% crude protein, with a metabolic energy (ME) of 2.900 kcal/kg. The cage system used is a battery colony cage measuring 200 cm x 60 cm x 50 cm with 30 plots. Each plot contained eight male Peking ducks which were kept until 8 weeks of age. The research data were analyzed using One Way Anova based on a Completely Randomized Design with a unidirectional pattern and followed by the Duncan Multiple Range Test (DMRT) using the SPSS version 16 program. The research results showed that the treatment with the addition of 10% fermented pineapple peel in the ration (P2) could produce a male Peking duck carcass percentage of 55.52% higher than the P0 treatment (54.94%); P1 (54.11%); P3 (53.85%); P4 (53.61%) and P5 (52.07%), while in primal carcass cuts the highest percentage was found in the chest at 37.17%, followed by the back (22.67%), wings (13.96%), lower thighs (13.72%) and upper thighs (12.43%).  Conclusion: The addition of yeast (Saccharomyces cereviceae) culture fermented pineapple peel at a level of 10% in the ration can produce a higher percentage of carcasses and carcass primal cuts of male Peking ducks compared to other treatments.
