Abstract

Endophytic fungi isolated from medicinal plants have high diversity and the secondary metabolites produced have biological activity. Endophytic fungi isolated from medicinal plants have been the subject of many studies on their diversity and biological activity, one of which is jambu mawar (Syzygium jambos (L.) Alston). S. jambos has long been used as a traditional medicine to treat infections caused by pathogenic bacteria in many parts of the world, including South Sumatra. This study purposed to explore the diversity of endophytic fungi isolated from the branches of S. jambos, the antibacterial activity of endophytic fungi extracts, the determination of the structure of the compounds, and the activity of the active compounds of the selected endophytic fungi. Observations of the morphological characteristics of endophytic fungi were macroscopically and microscopically. The endophytic fungal extracts were then tested for antimicrobial activity against test bacteria Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, and Escherichia coli using the Kirby-Bauer paper disk diffusion method. Isolation of pure compounds using a gravity chromatography column, the determination of the structure of the compound is determined based on 1H-NMR, 13C-NMR, HMQC, and HMBC spectroscopy. Four endophytic fungi, code SJC1–4, were isolated from a branch of S. jambos. The results of macroscopic and microscopic morphological characterization showed three genera of Botryosphaeria, Trichothecium, and Aspergillus. The endophytic fungal isolate SJC1 exhibited strong activity against Gram-positive bacteria and moderate activity against Gram-negative bacteria, while SJC2–4 showed moderate activity against the four bacteria. Molecular identification of SJC1 revealed that it was Botryosphaeria mamane. Isolation of SJC1’s pure compound yielded compound 1, which was identified as 5-acetyl-6-hydroxy-3-methyl-2H-pyran-2-one. This compound is thought to have antibacterial properties.

Abstract

Abstrak Program pengabdian kepada masyarakat ini dilaksanakan dengan tujuan meningkatkan pengetahuan dan keterampilan ibu-ibu Pemberdayaan Kesejahteraan Keluarga, organisasi perempuan tingkat desa (PKK) Desa Pulau Semambu dalam budidaya dan pemanfaatan Tanaman Obat Keluarga (TOGA). TOGA dipilih sebagai alternatif peningkatan kemandirian kesehatan berbasis potensi lokal. Permasalahan utama mitra adalah rendahnya literasi kesehatan terkait jenis tanaman obat, manfaat, serta teknik pengolahan dan pemanfaatannya untuk penanganan penyakit ringan. Selain itu, belum tersedia media edukasi yang dapat diakses sebagai panduan praktik berkelanjutan. Kegiatan ini dilakukan melalui beberapa tahap: survei awal, sosialisasi, pelatihan budidaya dan pengolahan TOGA, penyediaan buku saku dan media digital, serta pendampingan lapangan. Metode pelaksanaan menggunakan pendekatan partisipatif melalui penyuluhan, praktik langsung, dan pendampingan berkelanjutan. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman peserta tentang tanaman obat dan penerapannya dalam kehidupan sehari-hari. Mayoritas peserta menyatakan mendapat pemahaman baru terkait budidaya TOGA dan mulai menerapkannya di pekarangan rumah. Selain itu, kegiatan ini juga menumbuhkan kesadaran kolektif tentang pentingnya pemanfaatan tanaman obat sebagai solusi kesehatan yang mudah diakses, ekonomis, dan ramah lingkungan. Rencana tindak lanjut berupa pembentukan Kelompok TOGA Desa Pulau Semambu dan pendampingan lanjutan disusun untuk menjamin keberlanjutan program. Kegiatan ini diharapkan tidak hanya menambah kemampuan pengetahuan masyarakat, tetapi juga memperkuat ketahanan kesehatan keluarga dan mendukung pelestarian kearifan lokal berbasis tanaman obat. Kata kunci: tanaman obat keluarga; literasi kesehatan; keterlibatan masyarakat; pelestarian pengetahuan lokal; ketahanan kesehatan keluarga. Abstract This community service program was developed to address low health literacy regarding medicinal plants and inadequate access to educational resources in Semambu Island Village. The initiative aimed to enhance PKK women's knowledge and skills in cultivating and using Family Medicinal Plants (TOGA) as a sustainable, accessible health solution. Through a participatory approach encompassing surveys, socialization activities, hands-on training in TOGA cultivation and processing, distribution of educational materials, and continuous field mentoring, the program engaged community members directly in the learning process. Results revealed significant improvements in participants' understanding of medicinal plant types, their health benefits, and processing techniques. Most notably, the majority of participants successfully implemented TOGA cultivation in their home gardens and began applying herbal remedies to manage minor illnesses. Beyond individual skill acquisition, the program fostered collective awareness about medicinal plants as an economical and environmentally friendly alternative to conventional healthcare. To ensure long-term sustainability, the Semambu Island Village TOGA Group was established with plans for ongoing mentoring. This initiative not only enhanced community capacity and health literacy but also strengthened family health resilience while preserving valuable local knowledge about medicinal plants for future generations. Keywords: family medical plants; health literacy; community engagement; local wisdom preservation; family health resilience.
