Traditional bamboo shoot fermentation is a hereditary practice still preserved by the people of Panti Village, Pasaman Regency. This process not only serves as a natural preservation method but also makes an important contribution to the formation of distinctive flavors and increases the nutritional value of bamboo shoots. One key aspect of this fermentation process is the activity of microorganisms, particularly lactic acid bacteria, which play a role in the production of metabolites such as lactic acid, which functions as a natural preservative, inhibits the growth of pathogenic microbes, and contributes to the distinctive flavor and aroma of fermentation. The main objective of this study was to isolate and identify the types of lactic acid bacteria found in traditionally fermented bamboo shoots. Fermented bamboo shoot samples were taken from several local production houses in Panti Village. The microbial isolation process was carried out using selective media MRS (de Man, Rogosa, and Sharpe) agar, which is commonly used for the growth of lactic acid bacteria. The obtained isolates were then analyzed through colony morphology observation, Gram staining, and microscopic tests to determine initial characteristics. Further identification was carried out through a series of biochemical tests to determine the genus and species of the bacteria. The results of the study showed the presence of several Gram-positive, rod-shaped bacterial isolates that are strongly suspected to belong to the lactic acid bacteria group, such as Lactobacillus plantarum. This bacterium is known to have probiotic potential and functional benefits in fermented food products. These findings indicate that traditional fermented bamboo shoots can be a potential source of functional bacterial isolates that are beneficial for the food industry, particularly in the development of probiotic products, natural preservatives, and food additives based on local fermentation. This study emphasizes the importance of preserving local wisdom in food fermentation practices as a foundation for sustainable, culturally aware food technology innovation and supporting food security based on local resources.

Tempoyak is a traditional Indonesian fermented food made from the flesh of durian (Durio zibethinus Murr.), which undergoes spontaneous fermentation driven by indigenous microorganisms. The fermentation process generally occurs under anaerobic conditions and is primarily dominated by lactic acid bacteria (LAB), including species such as Lactobacillus, Leuconostoc, and Pediococcus. These bacteria play a crucial role in modifying the physicochemical properties of the product, including a significant reduction in pH, an increase in the concentration of organic acids, and the formation of volatile compounds responsible for tempoyak’s distinctive aroma and overall flavor complexity. In addition to enhancing its unique sensory profile, the fermentation process also extends the shelf life and introduces probiotic potential to the final product. This study aims to observe and analyze the microbiological and chemical aspects of tempoyak fermentation and to evaluate its potential as a local functional food with health-promoting properties. Laboratory tests and microbial analyses confirmed that the fermentation process not only retains essential nutrients but also promotes the growth of beneficial bacteria, provided the production conditions are hygienically maintained at all stages. The study emphasizes the importance of controlled fermentation techniques to ensure product safety and consistent quality. Furthermore, the findings reveal that tempoyak could serve as a promising probiotic-rich food that supports digestive health, contributing to the diversification of traditional Indonesian fermented foods. With its appealing flavor, cultural value, growing consumer interest, and potential health benefits, tempoyak holds significant promise for future development and commercialization, particularly in the field of functional food innovation rooted in indigenous culinary practices.

Based on the observations that have been made, it is shown that students' mathematical communication skills are still relatively low so that an innovative learning model is needed to improve students' mathematical communication skills. This study aims to see whether the improvement in students' mathematical communication skills taught with the Two Stay Two Stray cooperative learning model is higher than the mathematical communication skills of students taught with the Think Pair Share cooperative learning model and to see how the improvement in mathematical communication skills taught with the two models. This study is a study that is included in the quasi-experimental category with a pretest-posttest control group design. The subjects in this study were 62 students in grades VIII-A and VIII-E of SMP Negeri 4 Balige. Based on the research that has been done, the results of the N-Gain test were obtained with an average N-Gain value in experimental class 1, namely 0.813 in accordance with the Gain index criteria in the high category and the average N-Gain value in experimental class 2, namely 0.693 in accordance with the Gain index criteria in the medium category. Based on the research that has been done, because the data is normally distributed and homogeneous, the hypothesis test is carried out using the t-test. Through the t-test that has been done, it was obtained that , namely 2.465>2.000. Therefore  is rejected, which means that the increase in mathematical communication skills of students taught with the Two Stay Two Stray cooperative learning model is higher than those taught with the Think Pair Share cooperative learning model.

Good mastery of programming algorithms is absolutely necessary for people who want to study computer science or mathematics. Therefore, this article aims to help readers who want to learn the importance of programming algorithms through basic concepts. This paper uses a literature review method from various types of existing sources to discuss history, function and properties, algorithm structure, notationincluding natural, pseudocode and flowcharts.
 

This study aims to analyze the difference in students' reading comprehension ability between innovative and conventional teaching methods. The research uses a quantitative approach with a quasi-experimental design. The sample consists of 30 students, divided into two groups: the experimental group using innovative learning and the control group using conventional learning. Data was collected through a reading comprehension test and analyzed using an independent t-test. The results showed a significant difference between the two groups, with a t-value of 2.419 and a Sig.
