Abstract

This study aims to examine the potential of microorganisms in Indonesian local fermented foods as functional food through a qualitative descriptive approach using literature review. Traditional fermented foods such as tempeh, oncom, shrimp paste (terasi), brem, lemea, kabuto, poteng reket, and swansrai are cultural products rich in various microorganisms, including Rhizopus sp., Neurospora sitophila, Lactobacillus sp., and Saccharomyces cerevisiae. These microorganisms play essential roles in the fermentation process, producing bioactive compounds such as lactic acid, probiotics, proteolytic enzymes, and B-complex vitamins that provide physiological benefits beyond basic nutritional functions. Fermentation not only enhances nutritional value and food safety but also offers positive health effects, including maintaining gut microbiota balance, boosting immunity, reducing the risk of degenerative diseases, and serving as natural antimicrobials and antioxidants. Data were collected from national and international scientific literature published in the last ten years. The findings indicate that Indonesian local fermented foods hold great potential to be developed into functional foods based on local wisdom. With appropriate utilization of natural microorganisms, traditional Indonesian foods can contribute to food security, public health, and the sustainable development of the functional food industry.

Abstract

Local Ecological Knowledge (LEK) and Traditional Ecological Knowledge (TEK) play a crucial role in mangrove ecosystem management, restoration, and community livelihoods. Over the past decade, scholarly interest in this topic has grown, yet research remains scattered across regions and disciplines. This study employed a bibliometric analysis of Scopus-indexed publications from 2014–2024, focusing on LEK/TEK in mangrove ecosystems. A total of 93 open-access articles and conference papers were identified. Results show two major research clusters: (i) ecosystem restoration, conservation, and ecosystem services, and (ii) ethnobotany and medicinal applications of mangrove species. Global publication patterns highlight Indonesia, India, and Bangladesh as leading contributors, while citation impact is distributed across both ecological and ethnobotanical studies. Despite growing attention, gaps remain in cross-regional comparisons, integration of LEK/TEK into policy, and interdisciplinary approaches bridging ecological, cultural, and governance perspectives. The findings provide a comprehensive overview of global scholarship and highlight future directions to strengthen the role of LEK/TEK in sustaining mangrove ecosystems.

Abstract

Sponges have the potential to symbiont with bacteria that produce antibacterial compounds. This study was conducted to isolate and test the antibacterial activity of sponge symbiont bacteria. Bacterial isolates obtained were tested for antibacterial activity against Staphylococcus aureus, Bacillus subtilis and Escherichia coli using the Kirby-Bauer method. The identification results of both sponges have similarities with Clathria sp. and Hyrtios sp. symbiont bacteria obtained from both sponges as many as 16 isolates. Antibacterial activity testing had a weak inhibitory effect on isolates Sp1A, Sp2C, Sp2D and Sp2F, while Sp2J showed moderate inhibition against gram-negative and positive bacteria. The antibacterial activity of the whole supernatant of symbiont bacteria obtained the diameter of the inhibition zone with weak, medium and strong categories. Sp1A isolate supernatant was obtained, potentially able to fight Escherichia coli bacteria with a strong category as a representation of gram-negative bacteria and against gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus) classified into the medium category. In conclusion, 16 symbiont bacterial supernatants have antibacterial activity mostly active against gram-negative bacteria Escherichia coli and gram-positive bacteria Bacillus subtilis. There are 6 isolates (Sp1A, Sp1B, Sp1E, Sp1F, Sp2D, Sp2F) active as antibacterial against Staphylococcus aureus with weak and moderate categories.
