Abstract

Kombucha tea is a very interesting traditional drink because this tea is the result of fermentation carried out by a symbiotic culture. The symbiotic culture is SCOOBY (Symbiotic Culture Of Bacteria And Yeast). The tea that can be used is green tea. Green tea contains compounds such as tannins, caffeine, flavonols, flavonoids, alkaloids and saponins. Different types of tea can affect the color of the kombucha. The fermentation time for kombucha tea is 7-14 days. Fermentation time can affect the degree of acidity and physical properties of kombucha tea. This research is a descriptive study which aims to determine the pH and organoleptic properties, namely taste, aroma, color and how to make kombucha tea. The research results showed that the pH of kombucha tea was 2 and in the organoleptic test, many panelists preferred green tea kombucha.

Abstract

Milk is one of the main sources of nutrition for children's growth and development. The quality of milk consumed plays an important role in ensuring that children receive adequate nutrition to maintain their health. One of the efforts of consumers to stop the development of microorganisms and maintain milk quality is to store milk in the refrigerator. The purpose of the study was to examine the effect of the length of storage of SGM formula (0-6 Months) in the refrigerator on the number of bacteria contained in it. The research design was a completely randomized design (CRD) with 6 treatments, namely 0, 1, 2, 3, 4, and 5 days of storage, replicated 3 times. The resulting data were analyzed statistically using Anova and Duncan's Multiple Range Test (DMRT). That Day 5, Day 4, and Day 2 had no significant difference in bacterial counts as they had the same notation 'a'. In contrast, Day 1 and Control, which had the notation 'b', were significantly different from the 'a' group, while Day 3 showed marginal differences with both groups

Abstract

Vegetables are rich in vitamins and minerals and are generally widely consumed by the public. One popular type of vegetable is lettuce because of its attractive texture and color. The cleanliness of vegetables is very important to prevent diseases caused by food contaminated with pathogenic bacteria. In this study, the number of bacteria on lettuce leaves in three different markets in Padang city was tested. The method used was the laboratory observation method by diluting with 3 repetitions. The results showed that the number of bacterial colonies on lettuce in Pasar Raya was 93 colonies, in Pasar Gaung was 61 colonies, and in Pasar Pagi Lolong was 69 colonies. The placement of vegetables in Gaung Market which has a special row for vegetables can maintain the cleanliness of vegetables, while in Raya Market and Lolong Market there is no special placement for vegetables so that vegetables are vulnerable to contamination with other materials. Bacterial contamination of vegetables can come from various factors such as the planting process, spraying organic fertilizer, harvesting, and washing. Therefore, it is necessary to pay attention to hygiene and sanitation in processing and selling vegetables to prevent bacterial contamination.

Abstract

The consumption of chicken continues to rise each year. However, the complete nutritional content in chicken meat makes it highly favored by bacteria. The allicin content in garlic can prevent the growth of various microorganisms that can cause meat spoilage. This study aims to determine the effect of varying concentrations of garlic solution (Allium sativum) on bacterial growth in chicken meat. The method used is an experiment employing a Completely Randomized Design (CRD) with three treatments: marinating chicken meat in garlic solution at concentrations of 0% (Control), 10%, and 20%, each with three replications. The research was conducted in November 2024 at the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, State University of Padang. The results obtained indicate that the optimum concentration of garlic solution as an antibacterial compound is 10%, with an average total microbial count of 2,3 x 104 cfu/g

Abstract

Ecoenzyme is a fermented liquid product containing lactic acid bacteria in fruits and vegetables. Nutrients derived from ecoenzymes such as nitrogen are used for growth. This study evaluated the effect of ecoenzyme administration on the number of Trichoderma asperellum spores in brown glutinous rice medium. Trichoderma asperellum is known as a beneficial fungus in the decomposition of solid waste and the enhancement of plant growth. The use of medium made from brown glutinous rice was tested as an alternative to Potato Dextrose Agar (PDA), with the addition of ecoenzyme as an additional nutrient. This study used a Complete Randomized Design (RAL) with six treatments and five repeats. The treatment given is the addition of ecoenzyme concentrations of 0%, 20%, 40%, 60%, 80%, and 100%. Data was analyzed using fingerprints and follow-up tests with DNMRT at an error rate of 5%. Observation of the number of spores is carried out at the age of 60 days by dilution and hemasitometer. The results showed that the 60% ecoenzyme concentration had the highest average spore count and was different from the 0% control. In contrast, the 20% concentration had the lowest average and was the same as the controls. Giving ecoenzyme to brown glutinous rice medium can increase the number of Trichoderma asperellum spores.

Abstract

This study aims to analyze dextran-producing bacteria, especially from the general Leuconostoc, Weissella, and Lactobacillus, which produce the enzyme dextransucrase for dextran synthesis. This research uses the Systematic Literature Review (SLR) method based on the PRISMA protocol, with data sources from various trusted scientific databases for the 2020–2024 period. The results of the study show that variations in dextran structure, such as molecular weight and degree of branching, are highly dependent on the bacterial strain and fermentation conditions. Optimization of production parameters, including pH, temperature and substrate concentration, can increase dextran production efficiency The conclusions of this study emphasize the need for a multidisciplinary approach to optimize the potential of dextran in industrial and biotechnology applications. Further research is recommended to explore new strains, optimize production processes, and diversify dextran applications.

Abstract

Enzim xilanase memiliki potensi besar dalam berbagai industri. Salah satu kegunaannya adalah dalam industri farmasi dan makanan karena kemampuannya mengubah xilan menjadi xilosa, sebuah gula rendah kalori. Selain itu, enzim xilanase juga digunakan dalam industri kertas sebagai agen pemutihan pulp (biobleaching). Xilanase dapat dihasilkan oleh bakteri termofilik dengan menggunakan xilan dari ekstrak jerami padi sebagai substrat. Produksi enzim dipengaruhi oleh nutrisi yang tersedia, seperti sumber karbon. Penelitian ini dilakukan untuk menentukan sumber karbon terbaik untuk meningkatkan aktivitas spesifik xilanase oleh bakteri termofilik amobil SSA2. Untuk menghitung aktivitas khusus xilanase, dibagi aktivitas xilanase dengan konsentrasi protein. Penelitian dilakukan di laboratorium departemen biologi FMIPA UNP dari November 2021 hingga Januari 2022 dengan menggunakan metode eksperimen yang mengikuti rancangan acak lengkap (RAL) dan melibatkan 5 perlakuan yang diulang sebanyak 3 kali. Temuan dari penelitian tersebut menunjukkan bahwa penambahan xilosa sebagai sumber karbon menghasilkan aktivitas khusus enzim xilanase tertinggi sebesar 1,536 Unit/mg. Kata kunci:  Xylanase, Sumber Karbon, Xylosa, Bakteri Termofilik.
