Abstract

Kolang-kaling is a half-ripe palm fruit. Its vitamins and minerals were efficacious in maintaining health. Kolang-kaling damage was characterized by a change in color to brown and a change in texture. Ingredients to maintain the quality for example cinnamon and clove extract. The purpose of this study was to determine the best concentration of cinnamon extract (0.3 %, 0.4 %, 0.5 %) and clove extract (0.4 %, 0.6 %, 0.8 %) as natural preservatives to the shelf life of kolang-kaling with optimal sensory properties. Kolang-kaling in syrup was stored at room temperature and observed the shelf life using conventional methods on days 0, 7, 14, 21, 28 and 35. Observed parameters include shelf life, pH, moisture content, protein, fat, degree of syrup brix, fierce levels, total plate numbers, and hedonic tests. Data analysis uses descriptive methods. The results showed that kolang-kaling in syrup with a concentration of 0.5 % cinnamon and 0.4 % cloves was preferred by hedonic panelists with a score of 3.05. The results of the total plate number test show the results of 3.1 x 104 colonies/gr, which means that it has not been able to meet the provisions of the Total Plate Number of SNI 01-4472-1998.

Abstract

Beef is a source of food that is much needed and consumed by humans, because it has a high protein content. Protein has a function as a building, regulatory, and replacement substance for body parts or tissue that has been damaged. In addition, protein can also be a source of energy and contains essential amino acids needed by the human body. Beef is widely marketed by sellers and is easily available. Beef can be used to become shredded so that it has added value. Housewives in Rantau Fajar Village Raman Utara District Lampung Timur Regency have a habit after completing household tasks, they do not have other jobs. Usually they visit each other with neighbors and chat which is of no use. The team for community service at the University of Lampung plans to conduct training in making beef shredded to train housewives who do not have jobs to have the skills to make beef shredded. The aim of the training in making beef floss for housewives in Rantau Fajar Village Raman Utara District Lampung Timur Regency is to provide knowledge and skills to housewives so that they have skills. With the acquired skills, it is hoped that they can increase their household income. The results of the community service that were carried out received a very enthusiastic appreciation from the community, as well as increased public knowledge about how to make shredded beef which has high nutritional value, as well as technology transfer in the form of a slicer that separates the oil content from beef shredded.

Abstract

Strawberries (Fragaria ananassa) are highly sought after for their vibrant color and unique flavor. However, their high perishability and rapid quality degradation lead to significant post-harvest losses and a decrease in market value. This study aimed to evaluate the effect of an edible coating based on WSC nanoparticles and PVA on the quality characteristics of strawberries during storage. The research methodology included the synthesis of WSC nanoparticles, preparation of the coating solution, application to strawberries, and subsequent storage. A Completely Randomized Design (CRD) with a single-factor arrangement was utilized, comprising five PVA concentrations (0%, 2%, 3%, 4%, and 5%) with three replications. The results demonstrated that the application of the nanoparticle WSC-PVA-based edible coating effectively reduced weight loss and delayed physical deterioration. Increasing PVA concentrations led to a more effective preservation of total soluble solids (°Brix), a lower weight loss percentage, and a slower decline in vitamin C content. Higher PVA concentrations were found to reduce the rate of quality degradation and moisture loss. The coating formulation containing 4% PVA (P3) exhibited the best performance, maintaining a water content of 92.24%, total soluble solids of 2 °Brix, a pH of 4.3, a weight loss of 30%, and a vitamin C retention rate of 9.02%. The findings of this study offer a valuable solution for farmers to mitigate strawberry quality decline and provide new insights for future research on food preservation.
