Abstract

Dangke, a dairy product of cow or buffalo, is a traditional food of Enrekang, South Sulawesi Province. Addition of papain in dangke preparation is responsible for the formation of solid texture of dangke. This study was aimed to find optimum conditions (temperature and concentration of papain enzyme) and their effects on physical, chemical, microbiological, and hedonic qualities of dangke. This study consisted of two stages: preparation of papain and dangke production with heating temperatures (70, 80, and 90 °C) and papain treatments (0.2%, 0.3%, and 0.4%). The experiment was conducted in a completely randomized design with a 3 x 3 factorial arrangement with three replicates. The first factor was the processing temperature consisted of 3 levels i.e., 70, 80, and 90 °C.  The second factor was the papain concentration consisted of 3 levels i.e., 0.2%, 0.3%, and 0.4%. The obtained data were evaluated using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test to observe the significances among treatments. Papain and amino acids were characterized using descriptive methods and organoleptic study was performed by non-parametric test (Kruskal-Wallis). The highest protein concentration was found in commercial papain (Merck, 360.63 mg/100 g), while the protein content of papain used in this study was of 323.21 mg/100g. However, these enzymes had similar molecular weight of 19.17 kDa. The optimum condition of dangke preparation was found at heating temperature of 80 °C and 0.3% of papain concentration, resulting in the most desirable characteristics of dangke in terms of chemical, physical, and microbiological properties as well as hedonic evaluation.

Abstract

Whey from the dangke processing center in Enrekang district, South Sulawesi, is the main by-product which can contribute to environmental pollution. On the other hand, the nutritional content of whey is highly potential to be developed into high value food products and provide functional benefits. Whey processing into a fermented drink is one of the easy and inexpensive alternatives with good prospect to be developed. The aim of this study was to investigate the microbial, physical, chemical and sensory characteristics of the whey drink fermented (FWD) by probiotic lactic acid bacteria (LAB) isolated from dangke. The LAB strain used were Lactobacillus fermentum strains B323K, C113L, A323L, C222L, and B111K. The results showed that the LAB strains grew well the whey medium and the viability met the standard of dairy fermented product. FWD have similar pH, % titratable acidity, and aW characteristics in all fermentation treatments with LAB strains from dangke, however to adjust the pH and acidity level of FWD to the yoghurt standard (pH 4.4 and %TAT 0.9–1.2%), the FWD fermentation must be stopped at the 20th hour. Changes in the level of moisture, ash, and carbohydrate contents of FWD occurred after the fermentation. The sensory quality tests showed that the FWD fermented by LAB strains from dangke was preferred by the panelists than the unfermented one (Whey + 8% sucrose).

Abstract

Pathogenic bacterial contamination found in fresh cow's milk can be caused by poor milking management. This traditional milking process allows the milk to be contaminated from bacteria and dirt. Dyeing dairy cows using a commercial antiseptic is a common measure that can be done to prevent mastitis. Nipple immersion can be done after milking using synthetic antiseptic agents such as povidone iodine and chlorine. However, the use of synthetic antiseptics can actually cause a slight irritation and allergic effect and leave a residue. Therefore, it is hoped that the use of natural-based antiseptics can replace synthetic antiseptics. One of the natural based antiseptics that can be used is bacteriocin. This research aimed to analyze the application of the plantaricin IIA-1A5 as a substitute for synthetic antibacterial for teat dipping before milking namely microbiological tests, physicochemical tests, and pH measurements. The study was conducted using a randomized block design (RBD) with three replications. The treatment design consisted of control (without immersion), plantaricin 0.0074%, and povidone iodine 0.2%. Results showed application of plantaricin IIA-1A5 as teat dipping before milking can reduce the Total Plate Count, Escherichia coli, and Staphylococcus aureus population. The use of plantaricin IIA-1A5 as teat dipping did not change pH value and physicochemical quality (fat, SNF, lactose, and protein), which is below the Indonesian National Standard (SNI) about fresh milk. This ability is comparable to the iodine group, a synthetic antibacterial widely used by smallholder breeders in Indonesia. It is concluded that plantaricin IIA-1A5 can be used as a substitute for synthetic antibacterial (iodine group) for teat dipping before milking.

Abstract

This research aims to measure supply chain performance of dairy concentrate in cooperative with the SCOR-AHP approach and develop improvement based on the performance result, and to analyze the quality suitability as a basis to develop a comprehensive quality standard and its quality control mechanism. This research was conducted at a dairy farmer cooperative located in West Java. The analysis used to measure the performance was supply chain operation reference-analysis hierarchy process (SCOR-AHP). For measuring the product quality, ten post-production concentrate samples, 27 samples after the distribution process, and 25 samples for homogeneity test from five mixer machines were taken. Concentrate quality parameters were moisture, ash, crude fat, crude protein, crude fiber, total digestible nutrients (TDN), and salt content. Post-production samples data were compared with Indonesian National Standard (SNI) using one-tailed one-sample t-test, samples data from the field were tested using two samples independent t-tests compared to post-production samples data, and homogeneity test was seen from the coefficient of variation value of the salt content. The results show that the supply chain performance value of dairy cow concentrate at the cooperative is excellent. The nutrient content complies with SNI, but the homogeneity of the mixture is classified as poor category. The nutrient content of samples taken from the field shows differences with post-production samples except for TDN. The excessive total cost can be utilized to enhance performance in generating a better quality product. The cooperative should enhance homogeneity by concerning the mixing process and maintain the quality consistency by reformulating, stabilizing the quality of feedstuff, and calculating stock properly to avoid longer storage.

Abstract

There have never been specific research or study about cattle health during shipment using a Camara Nusantara ship as a mode of transportation. The objective of this study was to investigate the ship environment and physiological responses of cattle during transport from Tenau Port (Kupang) to Tanjung Priok Port (Jakarta) using Camara Nusantara 3 ship. The sample of 12 Bali cattle was determined using the purposive sampling total of 250 Bali cattle during transportation. Physiological parameters (including rectal temperature, respiratory rate, pulse rate) were used to evaluate the welfare status and stress level of animals, during the respective transport journeys. Transient changes in physiological parameters were found in the transported animals from day 2 to 4 relative to baseline levels, and the values were within the mild stress level of physiological range for the age of animals involved. There were significant differences (P<0.05) in rectal temperature, humidity, and temperature humidity index (THI). Using factorial Analysis of variance (ANOVA), there was an interaction between deck and day trip in the respiratory rate parameter. The cattle regained their initial normal range of physiological level and had slightly recovered by the time of their arrival on the 5th day of the journey.

Abstract

Bakteriosin adalah peptida dengan aktivitas antibakteri yang diproduksi oleh bakteri asam laktat dan digunakan sebagai pengawet alami. Penelitian sebelumnya menunjukkan bahwa Lactobacillus plantarum IIA-1A5 memproduksi bakteriosin yang diberi nama Plantarisin IIA-1A5 pada medium pertumbuhan yang dibuat dari whey yang diperkaya skim. Untuk aplikasi sebagai pengawet alami dan untuk memperbaiki masa simpan dan aktivitas anti mikrobanya, plantarisin perlu dienkapsulasi dan dikeringbekukan. Tujuan dari penelitian ini adalah untuk mengkarakterisasi dan mengevaluasi aktivitas antimikroba dari sediaan plantarisin IIA-1A5 yang terpurifikasi parsial dan terenkapsulasi kering beku. Ekstraksi dan purifikasi dari bakteriosin dimulai dengan presipitasi dengan ammonium sulfat, yang diikuti dengan dialysis, dan penukar kation kromatografi. Purifikasi parsial dari plantarisin kemudian dimikroenkapsulasi dengan maltodextrin kemudian dilanjutkan dengan proses kering beku. Berdasarkan pada SDS-PAGE, fraksi protein ke-7 (F7) dari plantarisin yang dipurifikasi parsial memiliki pita tunggal dan berat molekul sekitar 9,65 kDa. Konfirmasi lebih lanjut dengan menggunakan MALDI-TOF MS, ternyata pita tunggal tersebut terdiri dari 5 peptida yang diidentifikasi berbobot molekul masing-masing sebagai berikut 5,5, 7,80, 7,96, 9,09, dan 9,27 kDa. Plantarisin kering beku memiliki aktivitas antimikroba terhadap Staphylococcus  aureus tiga kali lipat dibandingkan dengan aktivitas antimikroba dari supernatan bebas sel, dan lebih tinggi dibandingkan dengan nisin, namun kurang bila dibandingkan dengan antibiotik ampisilin dan penisilin. Kesimpulannya, aktivitas antimikroba plantarisin kering beku dapat ditentukan dan lebih tinggi dibandingkan dengan nisin, ampisilin dan penisilin.Characterization of Plantarisin IIA-1A5 as Antimicrobial subtances and Evaluation of Acitivity of Freeze-dried Microencapsulated PreparationAbstractBacteriocins are peptides with antibacterial activity produced by lactic acid bacteria and used as natural preservatives. Previous studies showed that Lactobacillus plantarum IIA-1A5 produces bacteriocin named plantaricin IIA-1A5 in the medium consisting whey enriched with skim milk. For application as food preservatives and to improve its shelf-lie and activity, plantaricin was needed to be microencapsulated and freeze dried. The objective of this research was to characterize and evaluate the activity of partially purified freeze dried microencapsulated plantaricin IIA-1A5. Characterisation of partially purified plantaricin IIA-IA5 includes the identification of active fractions and molecular weight, evaluation of activity at different stage of purification and evaluation of antimicrobial activity of freeze dried microencapsulated plantaricin IIA-IA5. Extraction and prificafication of the bacteriocins started with precipitacion with ammonium sulfate, followed by dialysis, and cation exchange chromatography. The partial purified of plantaricin was then microencapsulated in maltodextrin followed by freeze drying. Based on SDS-PAGE, the protein fraction F7 of partially purified plantaricin had a single band and molecular weight about 9.65 kDa. Further analyses using MALDI-TOF, it revealed that five peptides were identified from one single band plantaricin with molecular weight 5.5, 7.80, 7.96, 9.09, and 9.27 kDa, respectively. The freeze dried plantaricin freeze showed antimicrobial activity against Staphylococcus aureus three times stringer as compared to the activity of cell free supernatant, and was higher than nicin, but less than antibiotic ampicilin and penicilin. As concusion, the activity of freeze dried plantaricin could be determined and had a higher value than nicin, ampicilin and penicilin.

Abstract

The aims of this study were to evaluate the quality of feedstuff as concentrate feed raw material, the quality of feed concentrate, and customer satisfaction toward concentrate quality produced by the cooperative. The parameters observed were nutrient contents (moisture, ash, crude protein, crude fat, and crude fibre) and physical quality (density, bulk density, and compacted bulk density). Farmer satisfaction was measured using customer satisfaction index (CSI) and gap analysis. The data obtained consisted of primary data (nutrient content of feedstuff and physical quality) and secondary data (nutrient content of concentrates) that were then analysed descriptively. Total respondents in the satisfaction analysis were 100 farmers. The results of this study indicated that feedstuff nutrient content varied, even though corn gluten feed (CGF) was in the range of Indonesian National Standards (SNI). The highest density and bulk density were limestone, and the highest compacted bulk density was salt, while the lowest physical quality was coffee chaff. Nutrient content of concentrate complied with SNI except for crude fat content. Meanwhile, the physical quality of the concentrate was still within the normal range. Farmer satisfaction was in the satisfied category with the highest gap values absence of foreign objects. Key words: concentrate feed, CSI, farmer satisfaction, feedstuff, quality
