Abstract

One think In the Parent Stock breeder farm is Scoring Fleshing in growing periode The purpose of this study was to examine the effect of the fleshing score on the production performance of parent stock hens and find problems in the form of deviations from the fleshing score along with evaluations, solutions, and improvement plans. The benefit of this research is to provide information and guidance for farm supervisors and managers regarding target fleshing. Measuring the fleshing score is done by directly measuring the thickness of the chicken breast muscles. The number of samples taken is 5% of the total population ( COBB 2022 ). The data processed by excel 2021 and descriptive analised in order to same with the filed. Fleshing score aims to maintain and monitor body weight so that it is maintained, not to be overweight or otherwise the chickens become too thin. Good fleshing will produce enough fat reserves. This fat reserve is useful for preparation before production. The next hope is that with sufficient fat reserves during production, peak production will be high and production performance will be more persistent. Hens in coops that achieve an ideal fleshing score (less fleshing score 2) in the growing period tend to show better performance during the laying period, lower depletion of laying, higher peak production, higher cumulative PE, and higher cumulative HE. Keywords: flashing score, parent stock, production performance

Abstract

Abiu (Pouteria caimito Radlk.) is a plant of Sapotaceae family that can be consumed fresh, processed, or as a medical product. The fruit and leaves of this plant contain bioactive compounds. This research aims to inform the interaction between leaf:fruit ratio treatment and foliar fertilizer on the quality of the abiu fruit. The study was conducted at Kebun Balungbang Jaya, Dramaga, Bogor, West Java Province, from July 2022 to November 2022. The experiment used a factorial split plot design. The main plot was a leaf:fruit ratio treatment (N1, 45 leaves:1 fruit, and N2, 30 leaves:1 fruit) on each tertiary branch, and the tiller plot was foliar fertilizer (P1: 1 g L-1, P2: 2 g L-1, and P3: 3 g L-1), which consisted of 3 replications. The results showed that treatment of the leaf-fruit ratio and foliar fertilizer did not affect the quality of the abiu fruit. The interaction between leaf:fruit ratio and foliar fertilizer had a significant effect on ATT, as indicated by the lowest acidity value in the leaf:fruit ratio treatment of 45:1 and a fertilizer concentration of 1 g L-1 with a value of 0.12% but has no significant effect on the external and internal quality of other fruits. Keywords: Bioactive compounds, sapotaceae, tertiary branch, titratable acidity

Abstract

Using food ingredients and/or processed food products contaminated with pork, whether unintentionally or intentionally, has become a growing concern and issue. This condition encourages the development of an accurate method for specifically detecting the presence or absence of pork contamination. The research was carried out on two different samples: (1) fresh pork to provide an in-house positive control and (2) samples of pork-based processed meat products (floss, meatballs, corned beef, and sausages), tested using DNA markers. The use of samples originating from processed pork food is to determine the effect of the processing process on DNA fragments and the robustness of the extraction method for the detection process used. The research aimed to detect pork DNA fragments using the quantitative polymerase chain reaction (qPCR) method. The study stages were extracting fresh pork and processed products using an RNA extraction kit, DNA extraction kit, and salt extraction, as well as measuring the purity and concentration of DNA/RNA using a spectrophotometer. The RNA extract was converted into complementary DNA (cDNA), and the DNA extract was analyzed using qPCR with specific primers for pork DNA (Sus scrofa). The results showed that the concentration of RNA and DNA extracts was 71.1–296.025 ng/uL and of various purity. All processed meat product samples and in-house positive controls were amplified in the Ct range of 23–28 ng/uL. In this case, the meat processing had no effect on the DNA of the processed meat products analyzed, so DNA fragments could be detected. DNA qPCR was more time efficient than cDNA qPCR because it did not require an RNA reverse transcription step. Keywords: beta actin, cycle threshold, fresh pork, pork DNA, qPCR

Abstract

The fruit known as wax apple, scientifically named Syzygium samarangense (Blume) Merr. & L.M. Perry, is a well-liked agricultural product originating from Demak Regency in the Central Java Province. When it is difficult to distinguish between different forms of an organism, using DNA barcoding to authenticate the identity of species based on their DNA is an important way. The psbA-trnH intergenic spacer is a commonly used molecular approach to analyse the genetic characteristics of plant species. This study investigated the psbA-trnH intergenic spacer profile of wax apple cultivars from Demak regency. The investigation revealed that the psbA-trnH intergenic spacer sequences of the S. samarangense cultivars, namely Madu Thailand and Madu Deli Hijau, had lengths of 535 and 492 base pairs, respectively. Both cultivars demonstrate a greater nucleotide composition of deoxyadenylic acid (A) and deoxythymidylic acid (T) in comparison to deoxycytidilic acid (C) and deoxyguanylic (G). The genetic distance between S. samarangense ‘Madu Thailand’ and ‘Madu Deli Hijau’ indicates a very tight relationship, with a value of 0.000. The psbA-trnH intergenic spacer proved to be insufficient in differentiating the S. samarangense cultivars from Demak regency, mostly because to its low capacity to discern between the wax apple cultivars. Keywords: Demak, psbA-trnH intergenic spacer, Syzygium samarangense, wax apple

Abstract

Extracellular enzymes produced by fungi can serve as a screening tool for entomopathogen candidates. Enzyme secretion ability is important in determining the virulence level of an entomopathogenic fungus. This study aims to see the potential of fungal isolates through chitinolytic, lipolytic, and proteolytic activities of five entomopathogenic fungal isolated from Bactrocera sp. imago from citrus plants. The research was carried out at the Microbiology Laboratory of the Department of Biology at the University of Lampung. Enzymatic activity is known through the method of observing the clear zone formed on agar media. Quantitative tests based on the calculation of enzymatic index values showed that Nigrospora sp. (IB1) had lipolytic activity, Penicillium sp. 2 (IB5) isolates had chitinolytic, lipolytic, and proteolytic activities. The isolates of Penicillium sp. 1 (IB2), Phytopthora sp. (IB3), and Gliocladium sp. (IB4) did not show the activity of the three enzymes. Keywords: Bactrocera sp., bioinsecticide, entomopathogenic fungi, enzyme

Abstract

Scots pine (Pinus sylvestris L.) wood is one of the most popular timber export products. However, its low durability can reduce the potential and utilization of the wood. Chemical modification is one of the solutions to overcome this drawback. Chemical modification using non-biocide materials such as glycerol and citric acid was carried out to improve the inferior properties of wood. The study aimed to observe the microstructure and evaluate the surface characteristics of glycerol and citric acid-modified scots pine wood. Scots pine wood was modified using glycerol and citric acid with weight percent gain (WPG) values of 20% and 46%. Surface characteristics were measured, including surface roughness, surface free energy (SFE), wettability, and bonding quality. The results show that chemical modification using glycerol and citric acid resulted in the structure of the pine wood being more filled and denser. The modification could also reduce the roughness of the wood surface, resulting in decreased SFE value, increased contact angle, and decreased wettability on the wood surface. It might cause a decrease in the bonding quality because the wood did not have the strength to mechanically lock with the paint. Glycerol and citric acid modified-scots pine wood can be considered for exterior application. Keywords: citric acid, glycerol, microstructure, scots pine, surface characteristics

Abstract

Salak (Salacca edulis Reinw.) in bunch form can be attractive to consumers because its own unique shape. The use of primary and secondary packaging can maintain fruit quality. This study aims to evaluate quality change of salak in bunches including physical damage, mechanical damage, physiological and microbiological damage. Salak bunches were stored for 22 days, with observations every 3 days to analyze fruit damage, TSS, weight loss, and fruit hardness. The study used a single-factor completely randomized design, involving 3 treatments: wooden crates (K1), cardboard without net foam (K2), and cardboard with net foam (K3). Data were analyzed descriptively, analysis of variance, and DMRT at the 5% level. Primary packaging was effective in reducing mechanical damage to fruit after 13 hours of transportation, with mechanical damage reaching 0 (zero) due to net foam. The type of packaging used had a significant effect on quality change of salak during storage, namely physical, physiological and microbiological damage, weight loss, hardness, and TSS. Cardboard packaging with net foam was the best treatment, showing low physiological and microbiological damage until the 16th day of storage, which amounted to 4.05, as well as a low rate of change in quality for 22 days. Keywords: Salak bunches, storage, packaging, fruit quality, transportation

Abstract

Padang satay is a typical West Sumatran food that is part of Indonesia's traditional heritage. The experiment was carried out to overcome the problem of decreasing the quality of padang satay products. The vacuum and sterilization method utilized retort pouch packaging, which was anticipated to preserve product quality for up to 21 days during storage at both room and cold temperatures. This study aims to assess the effectiveness of retort pouch packaging in maintaining the quality of satay products by examining their physical, chemical, and microbiological properties after being packaged in retort pouches and stored for 21 days. The research employed a completely randomized design with a factorial arrangement of 2 factors and 4 replications.. Replications were taken for each temperature and storage time. The results showed a significant interaction between cold temperature treatment and storage for up to 21 days, maintaining pH values, water activity, and microbiological quality. Furthermore, the interaction between room temperature and cold temperature treatment could not significantly affect antioxidant activity and MDA levels (p<0.05). In conclusion, padang satay packaging using retort pouch could improve and maintain physicochemical quality in pH, water activity, and microbiology. However, it could not increase antioxidant activity or reduce the MDA level of the product. Keywords: packaging, retort pouch, satay padang, temperature storage

Abstract

This study develops roselle yogurt ice cream by combining the probiotic benefits of yogurt with bioactive compounds from roselle flowers. Yogurt is produced through milk fermentation by lactic acid bacteria, while roselle flower extract is rich in anthocyanins and flavonoids known for their antioxidant, antibacterial, and anti-inflammatory properties. The research methods included a comprehensive analysis of physicochemical properties, nutritional content, microbiology, antioxidant activity, and organoleptic characteristics. Using a randomized complete design, data analysis employed ANOVA and the Least Significant Difference tests (P < 0.05), with sensory evaluation conducted using the Kruskal-Wallis test. The results of exploring the synergy between roselle yogurt and ice cream in varying proportions (20:80, 30:70, 40:60) showed that the treatment with a 30:70 ratio of roselle yoghurt (P2) was optimal in physicochemical characteristics such as pH 5.47, total titratable acidity 0.74%, overrun 75.61%, and meltdown rate of 26.98 minutes. P2 also exhibited the highest total antioxidant activity at 137 µg/mL, with good sensory acceptance from consumers. This experiment provided an understanding of the potential of roselle yoghurt ice cream as a product that meets increasingly selective consumers' nutritional and health needs. It is hoped that these findings will stimulate the development of ice cream products that are not only commercially popular but also provide significant health benefits. Keywords: roselle yoghurt ice cream, antioxidant activity, consumer health
