Lactic Acid Bacteria (LAB) are a group of Gram-positive, cocci or rod-shaped microorganisms characterized by their catalase-negative phenotype. These bacteria are known to produce various antibacterial compounds, including organic acids, hydrogen peroxide, carbon dioxide, and bacteriocins, which exhibit bacteriostatic or bactericidal properties against pathogenic bacteria. The aim of this study is to isolate LAB that produce antibacterial compounds during the fermentation of Pakoba fruit (Syzygium luzonense) into sweets, with a focus on inhibiting the growth of Escherichia coli and Staphylococcus aureus. This research employs a quantitative descriptive method, involving the isolation of LAB from candied Pakoba fruit samples and subsequent testing of their antibacterial activity against the aforementioned pathogens. The barrier zone formed around the wells is then measured. The data from the study showed that BAL isolation from Pakoba fruit candied was obtained from as many as 10 isolates, and antibacterial activity tests showed that 10 BAL isolates produced antibacterial compounds with inhibitory diameters of 7.6 – 15.3 mm. The isolates with the greatest antibacterial activity are LAB isolate MP(1)5.2 for E. coli and LAB isolate MP(3)6.3 isolates for S. aureus. Based on the results of identification using the profile matching method, it was shown that the selected LAB isolates, namely MP(1)5.2 and MP(3)6.3, were classified in the genus Lactobacillus with the characteristics of stem cell shape, single cell arrangement, catalase-negative, non-motile, did not form spots, and did not produce gas from glucose.

Tridax procumbens L. and Aloe vera L. are plants commonly used in the treatment of burns. This study was conducted to determine the effect of giving a combination gel of T. procumbens and A. vera leaf extract on second-degree burn healing in mice. This study used 24 male mice (Mus musculus) which were divided into four treatment groups, namely positive control (KP, Bioplacenton®); negative control (KN, gel base); leaf extract of T. procumbens 0.5% and A. vera 0.5% (P1); and leaf extract of T. procumbens 1% and A. vera 0.5% (P2). The process of inducing burns on the backs of mice requires the use of a 1x1 cm iron, which is subjected to heat in a fire for three minutes. The iron is placed on the mice's back for five seconds, which leads to the development of a second-degree burn. The gel was applied twice a day for 21 days. The highest level of burn wound healing was recorded with the Bioplacenton® treatment, which achieved a full recovery of 100% on day 15. Following this, the combined gel treatment of 1% T. procumbens leaf extract and 0.5% A. vera also reached 100% healing by day 18. While it may not be as potent as Bioplacenton®, the gel formulation containing 1% T. procumbens and 0.5% A. vera leaf extract presents a viable alternative for treating second-degree burns.

Turtles They are among the world's protected animals and one of the rare, almost extinct species. The preservation of their habitat and knowledge of the traits of turtle-friendly habitats are two ways that the rescue and protection of these turtles must go on. For rescue operations, turtle sustainability, and sustainable coastal management, research is being conducted on the features of the turtle nesting habitats on Popareng Beach. This research aims to determine the characteristics of turtle nesting habitats and identify the parameters that hinder turtles from nesting at Popareng Beach, Tatapaan District, South Minahasa Regency. The method used in this research is the descriptive-exploratory method. With characteristic parameters consisting of beach width measurement, beach slope, sand temperature, sand humidity, sand texture, beach vegetation, and the presence of predators. From the research results, it shows that station 1 and station 2 have results that are suitable for turtle nesting habitats, with values obtained at station 1 being 88.33% and station 2 being 92%. Meanwhile, at station 3, with an evaluation score of 72%, it is considered fairly suitable and the station has tolerable limitations.

Red beans are a horticultural crop belonging to the annual legume group that grows upright and has a fairly high nutritional content. To obtain maximum growth and yield from red beans, several factors must be considered, including balanced fertilizer application. The factor of providing organic fertilizer from chicken manure with the right dosage is the target of this study. This study aims to determine the effect of red bean growth on the dosage of chicken manure fertilizer. This study was conducted from December 2024 to February 2025 and was carried out on the plantation land of the Department of Science Education, Faculty of Mathematics, Natural Sciences and Earth Sciences, Manado State University. The method used is a quantitative method with a type of experiment in the form of a Randomized Block Design (RAK) with five treatment combinations with each repeated three times. A0 = 0 (control), A1 = 1.00 kg, A2 = 1.50 kg, A3 = 2.00 kg, A4 = 2.50 kg, so there are 15 experimental bed units, and the data obtained are then analyzed using analysis of variance (ANOVA). The results of this study indicate that good plant height growth, number of leaves and stem diameter are found in treatment A1 with a dose of 1.00 kg of chicken manure fertilizer and A2 with a dose of 1.50 kg of chicken manure fertilizer because there is the most maximum growth.
