Program “Gotong Royong Komunitas Sabtu Bebas Sampah” di Negeri Passo dilaksanakan sebagai upaya pemberdayaan masyarakat dalam meningkatkan kebersihan lingkungan dan memperkuat kohesi sosial melalui kolaborasi antara mahasiswa Kuliah Kerja Nyata (KKN), pemuda, pemerintah negeri, pemerintah kecamatan, dan masyarakat setempat. Pemilihan program ini didasarkan pada pentingnya pengelolaan sampah berbasis partisipasi masyarakat sebagai solusi terhadap permasalahan lingkungan. Metode pelaksanaan dilakukan melalui observasi lapangan, koordinasi dengan pemangku kepentingan, serta pelaksanaan kerja bakti kolaboratif. Hasil observasi menunjukkan bahwa masyarakat telah memiliki sistem kebersihan yang terstruktur dan terdapat kebijakan pemerintah terkait pembersihan wilayah pesisir, sehingga program mengalami penyesuaian agar tetap relevan dan mendukung kebutuhan komunitas. Kegiatan yang dilaksanakan dalam tiga tahap kerja bakti, meliputi pengangkutan sampah rumah tangga dan pembersihan pesisir pantai, menunjukkan peningkatan kebersihan lingkungan, terbentuknya sinergi lintas komunitas, serta meningkatnya kesadaran dan partisipasi masyarakat dalam pengelolaan sampah berbasis gotong royong. Program ini menegaskan bahwa pengabdian masyarakat yang adaptif dan kolaboratif berkontribusi penting terhadap keberlanjutan pengelolaan lingkungan di Negeri Passo

Cajuput (Melaleuca spp.) is a high-value non-timber forest product in Seram Island, Maluku. The quality of cajuput oil is primarily determined by its 1,8-cineole (eucalyptol) content, which is influenced by genetic, environmental, and raw material factors. This study analyzed the effects of species, growing location, and raw material condition on the yield and chemical composition of oil derived from Melaleuca leucadendra and Melaleuca cajuputi collected from Hatusua and Eti villages, using distillation and GC-MS analysis. The results showed that fresh leaves yielded higher amounts than dried leaves. The highest yield was obtained from M. leucadendra from Eti (1.022%), while the lowest yield was recorded from dried leaves (0.008%). M. leucadendra oil was dominated by eucalyptol (56.62–58.50%), whereas M. cajuputi was dominated by methyleugenol (81.61%) with a lower yield (0.1213%), reflecting differences in genetically controlled metabolic pathways. Environmental factors influenced yield and minor compounds without altering the dominant constituents. Overall, the quality and quantity of cajuput oil are determined by the interactions among genetic, environmental, and post-harvest factors. The use of fresh raw materials, appropriate species or chemotypes, and optimal growing locations is key to improving oil quality and ensuring consistent production.

Pengelolaan limbah tempurung kelapa yang selama ini kurang dimanfaatkan menjadi masalah lingkungan sekaligus peluang ekonomi bagi masyarakat di Desa TNS, Kabupaten Maluku Tengah. Program pengabdian kepada masyarakat ini bertujuan memberdayakan kelompok pemuda untuk mengolah limbah tersebut menjadi briket sebagai sumber energi alternatif, sekaligus meningkatkan kemandirian ekonomi berbasis potensi lokal. Metode pelaksanaan mencakup survei awal, sosialisasi, pelatihan teknis produksi briket, pendampingan lapangan, dan evaluasi, dengan pendekatan partisipatif agar masyarakat aktif terlibat dalam setiap tahapan kegiatan. Hasil kegiatan menunjukkan peningkatan kapasitas produksi hingga 50 kg briket per minggu dengan kualitas stabil, terbentuknya kelompok usaha mikro, peningkatan keterampilan teknis dan manajerial masyarakat, serta pendapatan tambahan dari penjualan briket. Dampak sosial terlihat dari meningkatnya kesadaran lingkungan, budaya gotong royong, dan kolaborasi antara masyarakat dan pihak akademisi. Kelebihan kegiatan terletak pada relevansi dengan kebutuhan lokal, penerapan teknologi tepat guna, dan keberhasilan transfer pengetahuan, sedangkan keterbatasan mencakup peralatan produksi awal yang terbatas dan jaringan pemasaran yang masih perlu diperluas. Program ini memiliki potensi pengembangan lebih lanjut melalui peningkatan efisiensi produksi, diversifikasi produk, penguatan manajemen usaha, dan perluasan jejaring kerja sama untuk mendukung keberlanjutan usaha masyarakat.

Increasing antibiotic resistance has prompted the search for safer and more sustainable natural alternatives. Ipomoea pes-caprae, a coastal plant traditionally used for the treatment of wounds and inflammation, is known to be rich in secondary metabolites such as flavonoids, terpenoids, alkaloids, and phenolic acids that have potential antioxidant and antibacterial properties. This study aimed to map the metabolite profile of the methanolic extract of I. pes-caprae leaves using LC-HRMS, to analyze its relationship with antioxidant activity measured by the DPPH method, and to evaluate its antibacterial activity against Staphylococcus aureus and Escherichia coli. LC-HRMS analysis identified 406 compounds with Palmitic Acid as the dominant component (24.503%), including primary and secondary metabolite groups such as flavonoids (quercetin, rutin, kaempferol), phenolic acids (caffeic, ferulic, chlorogenic acid), terpenoids (caryophyllene oxide, lupeol), alkaloids, and phytohormones. The methanol extract showed moderate antioxidant activity (IC₅₀ = 136.71 ppm) and antibacterial activity against E. coli (inhibition zone 9.5 mm), which is thought to originate from the synergy of various secondary metabolites through free radical scavenging mechanisms and bacterial membrane damage. These findings strengthen the scientific basis for I. pes-caprae as a natural source of antioxidant and antibacterial agents for the development of natural pharmaceutical products.
