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

Ekosistem mangrove memiliki peran penting dalam menjaga stabilitas wilayah pesisir, mendukung keanekaragaman hayati, menyimpan karbon, serta memberikan manfaat sosial dan ekonomi bagi masyarakat pesisir. Namun, keberlanjutan ekosistem tersebut masih menghadapi berbagai tekanan akibat perubahan penggunaan lahan, pembangunan kawasan pesisir, pencemaran, dan rendahnya kesadaran masyarakat terhadap pentingnya konservasi mangrove. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memperkuat literasi lingkungan generasi muda melalui pemanfaatan media digital sebagai sarana kampanye konservasi mangrove. Sasaran kegiatan adalah mahasiswa dan pelajar dari berbagai latar belakang yang memiliki ketertarikan terhadap isu lingkungan dan media digital, dengan melibatkan 15 peserta dalam kegiatan lomba video pendek “Satu Menit Selamatkan Mangrove”. Metode pelaksanaan menggunakan pendekatan partisipatif-edukatif melalui tahapan persiapan, sosialisasi konservasi mangrove, penyusunan konsep dan produksi video, publikasi kampanye digital melalui Instagram, penilaian karya, serta evaluasi kegiatan. Hasil kegiatan menunjukkan bahwa peserta berhasil menghasilkan 15 video edukatif bertema konservasi mangrove. Kampanye digital yang dilakukan melalui Instagram mampu menjangkau sekitar 5.400 akun dan memperoleh sekitar 3.200 interaksi digital berupa tanda suka, komentar, dan berbagi. Kegiatan ini menunjukkan bahwa lomba video pendek berbasis media digital dapat menjadi strategi edukasi lingkungan yang kreatif, komunikatif, dan sesuai dengan karakter generasi muda. Program ini berkontribusi dalam meningkatkan partisipasi generasi muda dalam penyebarluasan pesan konservasi mangrove serta berpotensi dikembangkan secara berkelanjutan melalui evaluasi literasi lingkungan yang lebih terukur.

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.

Abstract. Pujirahayu N, Uslinawaty Z, Ritonga H, Hadjar N, Prasetya D, Dirvin, Gari A. 2025. Chemical profile, botanical origin, and antioxidant activity of stingless bees propolis from Konawe Island, Southeast Sulawesi, Indonesia. Biodiversitas 26: 2495-2507. This study aimed to determine the chemical profile, plant sources, and antioxidant activity of stingless bee propolis from Konawe Islands Regency, Southeast Sulawesi, Indonesia. Gas Chromatography-Mas Spectrometry (GC-MS) was used to determine the chemical composition of propolis. The antioxidant activity of propolis ethanol extract was then tested using the DPPH method. The results showed that 2 species of stingless bees, Tetragonula aff. biroi and Tetragonula sapiens exhibited chemical compounds with similarities and differences. These compounds consisted of triterpenes and diterpenes, such as 9,19-cyclolanost-24-en-3-ol, (3?.), 9,19-cyclolanost-24-en-3-ol acetate, lupenone, solanesol, norolean-12-ene, beta-amyrone, methyl commate b, ergosta-8,24(28)-dien-3-ol, 4,14-dimethyl-,(3?.,4?,5?), ?-amyrenone, and tricyclo[20.8.0.0(7,16)] triacontane, 1(22),7(16)-diepoxy. Others included phenolics, such as 3-[pentadecylphenol and 5-heptylresorcinol. A comparison of GC-MS analysis of propolis extract and plant exudates showed that the botanical origin of propolis was Anacardium occidentale (cashew), Mangifera indica (mango), and Artocarpus heterophyllus (jackfruit). Propolis ethanol extract from T. aff. biroi and T. sapiens had strong antioxidant activity with IC50 of 96.8 4±2.35 µg/mL and 49.5±0.42 µg/mL, respectively. Based on the results, the extract from two species of bees could be a potential source of antioxidant agents as medicinal ingredients and immune supplements in the food and pharmaceutical industry.

Abstract

Management of Forest Areas with Special Purposes requires an integrated approach that combines conservation, education, research, and community empowerment functions to support ecological and social resilience. The KHDTK UHO has strategic potential as a center for forestry knowledge development and innovation; however, its management faces several challenges, including unclear area boundaries, overlapping spatial utilization, limited community capacity, and suboptimal coordination among stakeholders. This community engagement program aimed to strengthen collaborative management of KHDTK UHO through a community empowerment approach and multi-stakeholder collaboration. The program was conducted in Tobimeita Urban Village, Nambo District, Kendari City, involving Halu Oleo University, Regional Section 1 of PSKL Sulawesi, the Southeast Sulawesi Provincial Forestry Agency, the Kendari City Government, Nambo District Government, Tobimeita Urban Village Government, Forest Farmers Groups (KTH), and community leaders. The methods applied included field observations, community outreach, Focus Group Discussions, stakeholder mapping, and participatory spatial mapping to identify potential resources, management challenges, and alternative solutions for sustainable forest area management. The results indicated that KHDTK UHO has significant potential to support biodiversity conservation and improve community livelihoods through the utilization of non-timber forest products (NTFPs). However, the optimization of these potentials remains constrained by spatial conflicts, limited processing technology, restricted market access, and weak community institutional capacity. Based on the analysis, five priority management strategies were formulated: participatory boundary delineation through spatial mapping, community-based forest rehabilitation, local resource-based economic empowerment, capacity building for local communities, and strengthening multi-stakeholder institutional coordination. A collaborative management approach that integrates academic capacity, Government policies, community experiences, and local knowledge represents an essential strategy for establishing KHDTK UHO as a sustainable educational forest area while generating ecological, social, and economic benefits for surrounding communities.
