Various recent studies have shown that natural active compounds contained in traditional and fermented plants play a crucial role in supporting human health. These compounds include flavonoids, polyphenols, tannins, saponins, alkaloids, organic acids, probiotics, and other phenolic compounds. Detection of these compounds is usually carried out through specific chemical reactions that allow researchers to more precisely identify the bioactive components. Their biological activities are diverse, including antioxidant, antibacterial, anti-inflammatory, and antimicrobial properties, which work to protect the body from cell damage and infection. Natural compounds are considered promising agents for disease prevention and health promotion due to their broad biological activities. The fermentation process has been shown to increase the content of bioactive compounds while lowering the pH of the medium, creating conditions unfavorable for the growth of pathogenic bacteria. Furthermore, probiotics that develop during fermentation play a role in maintaining the balance of the gut microbiota, strengthening the immune system, and improving digestive health. Fermented products are widely recognized as functional foods because they contain beneficial probiotics and enhanced bioactive compounds. These naturally derived products, rich in secondary metabolites, have also been shown to have significant physiological effects, such as lowering cholesterol levels, controlling blood sugar, and maintaining stable blood pressure. This makes natural ingredients and fermented products not only sources of nutrition but also have great potential for development as functional foods and traditional herbal medicines. This highlights the importance of integrating traditional knowledge with modern scientific approaches in developing functional foods and herbal medicines. Therefore, research on natural bioactive compounds and the role of fermentation in enhancing their effectiveness is highly relevant to supporting sustainable public health.

The Atur Dahar tradition is a ceremony to feed supernatural beings by leaving food overnight in a room, some are also drowned in the river. This tradition has become a hereditary custom by their ancestors. The existing actions are considered tabzir/wasteful and shirk. This study uses a normative empirical research type, the focus of this research is the views of religious leaders on the Atur Dahar tradition in Pait Village, Long Ikis District. The data analysis technique is carried out using a qualitative descriptive method, namely describing, explaining, and analyzing the results of the study by reviewing the study of 'urf. The procession of the Atur Dahar tradition in the celebration of the Banjar community in Pait village is divided into two implementations, namely dishes provided for ancestors, some are left overnight in the corner of the house and some are drowned in the river, but now the Atur Dahar tradition has been changed from food to which prayers are read and some have not changed, namely in the procession such as leftover food that becomes waste, and food that is less suitable or dirty is given to the community. Ten religious leaders agreed on the existence of the Atur Dahar tradition in celebrations if it complies with Islamic law. The Atur Dahar tradition is part of 'Urf Amali' because it is an act carried out by the community, especially the Banjar tribe in Pait village. This tradition is included in 'Urf Khash' because it is a custom of the Banjar tribe in Pait village. In terms of law, it is included in 'Urf Sahih', because some of the procession is in accordance with Islamic law, such as praying to Allah SWT and sharing food as alms with others. This tradition can also be included in 'Urf Fasid' because it is wasteful.

Bekasam is a traditional Indonesian fermented product made from tilapia (Oreochromis niloticus) through a spontaneous fermentation process with the addition of rice and salt. This fermentation process encourages the growth of various microorganisms, especially bacteria, which play a role in the formation of flavor, aroma, and natural preservation of the product. This study aims to observe the microbiological characteristics of bekasam tilapia through colony observation on agar media and microscopic staining using crystal violet and safranin. Macroscopic observations showed the presence of microbial colonies that were round, cloudy white, with a smooth surface and even edges. These colony characteristics indicate good microbial growth on agar media. Microscopically, the bacteria observed in bekasam samples had an irregular distribution, forming aggregates that absorbed intense purple and pink colors. Crystal violet staining gave a purple color to gram-positive bacteria, while safranin gave a pink color to gram-negative bacteria. These findings indicate that bekasam contains an active microbial community that plays a role in the fermentation process. This microbial community can be observed visually through simple staining that provides an overview of the types of bacteria involved in the fermentation process. Microbiological analysis such as this is crucial for understanding the fermentation dynamics of traditional food products like bekasam. Thus, this study provides deeper insight into the microorganisms involved in bekasam production, as well as the importance of monitoring microbiological quality in the manufacturing process of traditional fermented products. Furthermore, the diversity of microbes involved in bekasam fermentation can affect product quality and consistency. Therefore, monitoring the dominant bacterial species during the fermentation process is crucial for maintaining bekasam quality, including its taste, texture, and safety for consumers.

Tempoyak is a traditional fermented product derived from the flesh of durian fruit (Durio zibethinus) that has undergone a spontaneous fermentation process. This product is very popular in various regions in Indonesia, especially in Sumatra and Kalimantan, and is usually consumed as a cooking spice or side dish. The fermentation process primarily involves the activity of lactic acid bacteria (LAB), a group of microorganisms capable of converting acidic sugars into lactate. LAB plays an important role in forming the distinctive taste of tempoyak, lowering pH, inhibiting the growth of pathogenic microbes, and potentially providing health benefits for consumers. This study aims to isolate and characterize LAB from tempoyak using a microbiological approach. Tempoyak samples were taken from traditional markets, then isolated using MRS agar measurement media. Characterization was carried out through observation of colony morphology, Gram staining, and biochemical tests such as catalase and fermentation of various types of sugars (glucose, sucrose, and maltose). The isolation results showed that all isolates had the typical LAB characteristics, namely Gram-positive, catalase-negative, and rod- and coccus-shaped. The different sugar fermentation abilities indicate species diversity, with the suspected dominant genera being Lactobacillus, Streptococcus, Enterococcus, and Lactococcus. Furthermore, several isolates demonstrated antibacterial activity against Escherichia coli, indicating the potential use of LAB from tempoyak as a probiotic or natural preservative in the food industry. The decrease in pH from 6.2 to 3.6 during the fermentation process also confirmed the metabolic activity of LAB in acid-producing lactate. These findings open up opportunities for utilizing local LAB from tempoyak as functional agents in the development of safe, healthy, and economically valuable fermented food products. Thus, tempoyak not only has cultural value but also has significant scientific and commercial potential.

Bekasam is a traditional fermented fish product commonly produced in South Sumatra and South Kalimantan, known for its distinctive sour taste resulting from the metabolic activity of lactic acid bacteria (LAB). LAB play a crucial role in the fermentation process, contributing to the product’s flavor, texture, and safety. This study aimed to isolate, identify, and characterize LAB from bekasam made using tilapia (Oreochromis niloticus). Isolation of bacterial strains was performed using the pour plate method on Nutrient Agar (NA) medium at various serial dilutions to obtain discrete colonies. The colonies were observed macroscopically to assess their morphological characteristics, including shape, size, color, surface texture, and edge profile. Further identification involved Gram staining to determine cell wall type and microscopic morphology. The results revealed that the bacterial colonies were generally small, round, white to cream in color, with smooth surfaces and flat edges. Gram staining demonstrated that the dominant isolates were Gram-positive bacteria, exhibiting rod-shaped or oval morphology. These characteristics are consistent with members of the genus Lactobacillus sp., a common LAB group in fermented fish products. Additional phenotypic traits observed included catalase-negative reactions, absence of spore formation, and the ability to produce lactic acid as the main metabolic end product. The combination of morphological, staining, and basic biochemical characteristics supports the initial identification of the isolates as LAB. The presence of Lactobacillus sp. in bekasam suggests their significant contribution to the fermentation process, influencing the product’s sourness, safety, and preservation. The findings of this study provide a basis for further molecular characterization and potential selection of LAB strains as starter cultures to improve the quality, consistency, and safety of bekasam in traditional and industrial production.

This study examines the practice of reciprocity within the persatuan barang (goods-sharing) group during the implementation of the rewang tradition in Desa Banglas, Kecamatan Tebing Tinggi, Kabupaten Kepulauan Meranti. The main focus of the research is to identify the various forms of exchange that occur, whether in the form of money, goods, or labor. A narrative qualitative approach was used, with data collected through in-depth interviews, non-participant observation, archival review, and documentation of bookkeeping records. The subjects of this research are members of the persatuan barang group who actively participate in social and cultural events in the village. The findings reveal three types of reciprocity: generalized, balanced, and negative. Generalized reciprocity is evident in voluntary contributions without expecting immediate return, often practiced among close kin or neighbors. Balanced reciprocity is demonstrated through exchanges of equal value with a certain expectation of timely return, particularly during communal events like weddings or funerals. Negative reciprocity, although rare, involves unequal exchanges that may lead to social tensions or perceptions of unfairness. These findings indicate that the persatuan barang group functions not only as an informal economic mechanism but also as a cultural institution that fosters mutual assistance, reinforces social cohesion, and preserves traditional values. The exchange systems operate within an implicit moral economy that prioritizes collective welfare over individual gain. Additionally, the tradition of rewang and the organizational role of persatuan barang highlight the resilience and adaptability of indigenous practices in supporting rural livelihoods amid changing socioeconomic conditions. The study suggests that such local systems of reciprocity play a vital role in sustaining social capital, strengthening community identity, and ensuring social security in the absence of formal welfare structures. Further research is recommended to explore the long-term impact of these practices on community resilience and rural development.

Pedada leaves (Sonneratia caseolaris), a type of mangrove plant that grows in tropical and subtropical coastal areas, have high ecological and pharmacological value. In addition to functioning as coastal protection from abrasion and seawater intrusion, this plant is also known to contain various secondary metabolite compounds such as flavonoids, tannins, saponins, and alkaloids. These compounds have been widely reported to have important biological activities, one of which is as an antimicrobial agent. This study aims to identify the effectiveness of pedada leaf ethanol extract in inhibiting the growth of pathogenic microorganisms, especially bacteria that cause infections. The extraction process was carried out using 96% ethanol solvent through the maceration method, namely soaking the material in the solvent for a certain time to optimally obtain active compounds. The obtained extract was then tested for its antimicrobial activity using the disc diffusion method against test bacteria, both Gram-positive and Gram-negative. The inhibition zone formed around the disc was measured as an indicator of the antibacterial effectiveness of the extract. The results showed that pedada leaf extract was able to produce inhibition zones with varying diameters depending on the concentration used. The higher the extract concentration, the larger the diameter of the inhibition zone formed. This indicates a positive relationship between extract concentration and its antibacterial strength. This activity is believed to originate from the ability of compounds such as flavonoids and tannins to damage bacterial cell walls or disrupt microbial metabolic processes. This study provides initial evidence that pedada leaves have potential as an environmentally friendly and sustainable source of natural antibacterials. This potential is highly relevant in efforts to develop alternative antibacterial materials based on local plants, especially amidst increasing bacterial resistance to synthetic antibiotics.

Durian is a tropical fruit belonging to the climacteric group, meaning it experiences a surge in respiration after harvest and quickly deteriorates. Due to its perishable nature, processing is necessary to extend its shelf life and maintain its nutritional value and flavor. One traditional method of processing that has long been known in Indonesia, particularly in Kalimantan and Sumatra, is the fermentation of durian flesh into tempoyak. Tempoyak is a natural fermentation product made from ripe durian flesh that has undergone a further ripening process and has a distinctive sour taste and strong aroma. The tempoyak fermentation process involves the activity of microorganisms, particularly lactic acid bacteria (LAB) such as Lactobacillus plantarum and Lactobacillus curvatus, which play a crucial role in producing flavor, a semi-solid texture, and functional health benefits. Human food needs depend not only on the quantity of food but also on the quality of its nutritional content, such as carbohydrates, protein, fat, vitamins, and minerals. In this context, fermented foods such as tempoyak provide added value in the form of probiotics that have the potential to improve digestive health. Lactic acid bacteria, which dominate the natural fermentation process, play a crucial role in the formation of flavor compounds and beneficial biological activities. This study aimed to isolate and identify the types of LAB present in traditional tempoyak from Jambi. Isolation was conducted to obtain pure strains of bacteria with potential probiotics, while identification aimed to determine the dominant bacterial species in the tempoyak fermentation process. The results of this study are expected to contribute to the development of functional food products based on local fermentation.

Traditional salted fish is a widely consumed food product in Indonesia due to its high shelf life and distinctive flavor. However, the production process, which is generally carried out conventionally and openly, has the potential to cause contamination by pathogenic microbes, which can endanger consumer health. This study aims to identify and analyze the presence of pathogenic microorganisms in traditional salted fish products through a microbiological approach. Salted fish samples were taken from various traditional markets and analyzed using microbial culture methods, biochemical identification, and molecular confirmation for pathogenic bacteria such as Salmonella spp., Vibrio spp., Escherichia coli, and Staphylococcus aureus. The results showed that most contained pathogenic bacteria exceeding the threshold set by SNI and BPOM, indicating weak sanitation and hygiene control in the processing process. These findings emphasize the importance of implementing hygiene standards and quality control in the home industry of salted fish processing. Furthermore, environmental factors such as sea air quality, drying methods, the use of unclean containers, and minimal knowledge of business actors regarding hygiene practices are the main causes of contamination. In some locations, salted fish is dried directly on the ground or on unsterilized surfaces, increasing the risk of exposure to dust, insects, and microorganisms. The study also found that labeling and date information were not available on most products, making it difficult for consumers to assess their safety. As a preventative measure, educating producers and providing training on Good Manufacturing Practices (GMP) and Sanitation Standard Operating Procedures (SSOP) is crucial. Collaboration between the Health Office, the Food and Drug Monitoring Agency (BPOM), and local governments is also recommended to conduct regular inspections and provide food safety certification facilities for small businesses.
