Abstract

This study investigates the phytochemical composition, antioxidant, and antibacterial activities of stingless bee, Tetragonula sapiens propolis from four locations in Buton Utara, Southeast Sulawesi, Indonesia. Phytochemical screening confirmed the presence of flavonoids, tannins, and polyphenols in all samples, while alkaloids were absent. Antioxidant activity, measured by DPPH assay, varied significantly among samples, with Lakonea exhibiting the strongest activity (IC₅₀ 42.22 ppm), followed by Linsowu (66.33 ppm), Lemo Ea (85.13 ppm), and Lantagi (113.39 ppm). Antibacterial tests against Escherichia coli, Staphylococcus aureus, and Salmonella typhi revealed distinct inhibitory patterns, with Lakonea showing the broadest spectrum of activity at 30% concentration. Statistical analysis indicated a strong negative correlation (rₛ = -0.80) between IC₅₀ values and total antibacterial inhibition, suggesting that samples with higher antioxidant capacity tend to possess stronger antibacterial effects. The findings highlight the influence of geographical origin and botanical sources on the bioactivity of propolis. This study concludes that stingless bee propolis from Buton Utara, particularly from Lakonea, holds promising potential as a natural source of antioxidants and antibacterial agents, supporting its future application in the development of functional foods, nutraceuticals, and pharmaceuticals.

Abstract

The International Collaborative Community Service Program, conducted by the Forestry Study Program of the Faculty of Forestry and Environmental Sciences in collaboration with the University of Technology of Mara, Malaysia, aims to: Provide training on utilizing sengon/jabon wood waste (harvested) by converting it into wood pellets as a renewable energy source; and Increase the economic value of community forests by improving the quality of primary wood and creating value-added products from waste. This community service activity is implemented through outreach and practical training on making wood pellets from sengon/jabon waste, introducing the potential of wood waste as a renewable energy source. Techniques for collecting, drying, and shredding wood waste, as well as the process of molding the shredded waste into pellets, are also covered. After this activity, community forest farmer groups can utilize and convert previously unused waste from sengon and jabon felling into wood pellet products. Environmental benefits include more sustainable forest management and reduced wood waste, which can otherwise pollute the environment. The expected benefits for the partner (UiTM) include applying existing knowledge and technology in the context of international community service and strengthening collaborative networks.
