Bakasang is a fermented fish product traditionally made using the viscera (internal organs) of tuna (Thunnus spp.) and skipjack tuna (Katsuwonus pelamis), with the addition of a high concentration of salt, typically around 20% or more. The fermentation process occurs naturally and spontaneously through the activity of indigenous microorganisms, particularly those belonging to the lactic acid bacteria (LAB) group. LAB are Gram-positive, catalase-negative bacteria capable of producing lactic acid, which plays a crucial role in preservation and flavor development, and also possesses potential probiotic functionality. This study aims to evaluate the diversity and population of LAB in locally produced bakasang from the Bacan and Sanana regions, as a basis for the development of functional foods utilizing local microbial resources. Enumeration and isolation of LAB were conducted using the pour plate method on de Man, Rogosa, and Sharpe (MRS) agar, followed by morphological colony characterization, Gram staining, and physiological profiling. The results showed that LAB populations in bakasang samples from both regions ranged from 10⁵ to 10⁸ CFU/g. The LAB count in bakasang from Bacan (2.4 × 10⁸ CFU/g) was higher compared to that from Sanana (4.6 × 10⁵ CFU/g). Macroscopic, microscopic, and physiological characterization of the isolates indicated similarities to the genera Lactobacillus and Lactococcus. The diversity of LAB observed in this study reflects local microbiota with promising potential to be developed as fermentation agents and probiotics for the functional food industry.

Kegiatan pengabdian kepada masyarakat berlangsung pada lahan percontohan PKK di Kelurahan Maliaro Kota Ternate. Kegiatan diikuti oleh seluruh anggota PKK dan tim pengabdian masyarakat beserta mahasiswa yang dilaksanakan pada Mei 2024. Metode yang digunakan adalah penyuluhan dan pelatihan. Kegiatannya mencakup eksplorasi dan penanaman yang dilakukan secara langsung pada lahan percontohan. Eksplorasi meliputi kegiatan pembersihan gulma atau rumput liar di area lahan dan penggemburan tanah dan persiapan media tanam. Reboisasi atau penghijauan difokuskan dengan melakukan penanaman bibit tanaman kangkong, sawi dan jagung. Tujuan dari PKM ini adalah untuk meningkatkan pengetahuan kepada masyarakat tentang pentingnya menjaga kelestarian lingkungan melalui gerakan penghijauan. Kegiatan pengabdian ini mendapatkan apresiasi dari masyarakat khususnya PKK Kelurahan Maliaro. Kegiatan ini juga diharapkan dapat meningkatkan kesadaran masyarakat dalam menjaga kondisi lingkungan agar tetap lestari dengan langkah dan upaya sederhana seperti melakukan Gerakan penghijauan. Penamanam tanaman sayuran di lahan percontohan PKK Kelurahan Maliaro juga dapat dimanfaatkan untuk konsumsi sekaligus memberikan nilai ekonomi bagi masyarakat. Kata Kunci: Penanaman, Lingkungan, dan bibit tanaman sayuran

Ekosistem hutan mangrove merupakan perpaduan antara dua habitat yaitu terrestrial dan akuatik. Perpaduan ini menjadikan ekosistem hutan mangrove memiliki karakteristik khas, baik ditinjau dari segi fisiografi maupun keragaman biota yang terintegrasi dalam sistem ekologi mangrove. Menyangkut kerusakan hutan mangrove di Kao Teluk sekitar daerah Akesahu yang saat ini mengalami kerusakan yang cukup parah akibat dari aktifitas masyarakat yang selalu memnafaatkan potensi dari hutan mangrove setempat untuk dijadikan bahan kayu bakar maupun dijual serta digunakan sebagai bahan bangunan. Tujuan penelitian adalah untuk mengungkap status dari jenis-jenis mangrove yang ada di Kao TelukÂ sekitar daerah Akesahu. Metode yang digunakan adalah metode line transek ditarik tegak lurus dari garis pantai memotong vegetasi menuju ke arah darat dengan lebar belt transek 20 m. Parameter vegetasi yang diukur meliputi: densitas, frekuensi dan dominasi serta penentuan Indeks nilai penting (INP). Hasil penelitian menunjukkan bahwa mangrove jenis R. apiculata, R. mucronata, X. moluccensis, X granatum dan B. gymnorrhiza, yang dahulu banyak ditemui, namun sekarang populasinya menjadi semakin berkurang. Hal ini berarti jenis mangrove tersebut telah mengalami kerusakan yang cukup besar, sehingga dikhawatirkan jenis-jenis tersebut akan terancam beberapa tahun mendatang, maka pelu disegerakan upaya rehabilitasi maupun reboisasi secara cepat dan tepat guna penyelamatan plasma nutfah dimasa mendatang di daerah Akesahu tersebut.

Seagrass meadows are ecosystems consisting of one or more species of seagrass interacting with biotic and abiotic factors in their environment. Ecologically, seagrass has several important functions in coastal areas, one of which is seagrass as a primary producer in shallow waters which is a food source for several types of organisms. This research aims to find out the types of seagrass plants in the waters of Teluk Buli Village, and find out the pattern of seagrass plant distribution, and find out what environmental factors affect the growth of seagrass plants. This type of research is descriptive explorative, where the data collected includes the types of seagrass plants that have been identified, the pattern of seagrass plant distribution, and environmental factors that affect the distribution pattern of seagrass plants. The method used for data collection is the quadratic method (calculated plot). Analysis of seagrass plant type data using seagrass plant identification manuals, seagrass plant distribution patterns using morista spread index formulas, and environmental factors that affect the pattern of seagrass plant distribution are described and contained in observation tables. The results showed that the type of seagrass plant found in the waters of Teluk Buli Village was a type of Enhalus acoroides. The results of the calculation of the morista spread index showed that the seagrass plant Enhalus acoroides had a clustered distribution pattern with a value of Id 1. The results of measuring the environmental parameters of seagrass plants in the waters of Teluk Buli village, namely pH 5-6.6 categorized as acid, Humidity 20%-50%, and Salinity 28% - 31% Optimum category.

Penelitian ini bertujuan untuk menginventarisasi dan mengidentifikasi spesies Asteraceae di jalur pendakian Gunung Gamalama, Ternate, serta menganalisis distribusi tribus, potensi etnobotani, dan implikasi ekologinya. Metode yang digunakan adalah eksporasi jalur. Hasil inventarisasi mencatat 10 spesies yang tergolong ke dalam enam tribus dari dua subfamili, dengan dominasi Eupatorieae dan Senecioneae masing-masing 30%. Beberapa spesies yang ditemukan, seperti Ageratum conyzoides, Bidens pilosa, dan Mikania micrantha, merupakan gulma invasif yang berpotensi mengganggu regenerasi vegetasi lokal. Di sisi lain, spesies seperti Elephantopus mollis, Emilia sonchifolia, dan Erechtites valerianifolius diketahui memiliki nilai etnobotani dan aktivitas farmakologi penting. Temuan ini menunjukkan peran ganda Asteraceae di Gunung Gamalama, baik sebagai ancaman ekologi melalui invasi maupun sebagai sumber biofarmaka potensial. Hasil penelitian ini diharapkan menjadi dasar untuk pengelolaan kawasan yang mengintegrasikan konservasi dan pemanfaatan keanekaragaman hayati.
