The Optimal coral reefs are distributed in shallow waters between 0 and 30 m deep, influenced by the hydro-oceanographic variability of the waters. Globally, corals are distributed in various forms of water predominantly found in the Coral Triangle region. This study aims to examine the spatial distribution of coral biodiversity in the Tidore Island Waters. This study was conducted in the Tidore Island Waters at three research stations, namely Tugulufa Station, Toloa Station and Tanjun Konde Station. This study analyzed the spatial distribution of coral and the relationship between coral biodiversity and the hydro-oceanographic conditions of the Tidore Island waters. The results showed that the highest coral diversity was found at Toloa Station, with the largest area being the Acropora tabulate coral life form. Acropora coral species were found throughout the research location, with the highest percentage of cover found at Toloa Station. Temperature and salinity variables are the main characteristics in the three research locations. Temperature has a role and main characteristics in Toloa Station. The spatial distribution of Acropora corals is related to temperature and salinity variability.Keywords:Coral reefTidore waterTemperatureSalinity

Groundwater quality degradation in small volcanic islands presents complex challenges for freshwater availability, particularly where communities heavily rely on groundwater resources. A study of groundwater dynamics in dug wells on Ternate Island, Indonesia, examined the relationship between water volume changes and water quality parameters while evaluating seawater intrusion potential through hydrostatic balance analysis. Researchers measured physical parameters (temperature, surface pressure) and chemical parameters (salinity, dissolved oxygen, electrical conductivity, total dissolved solids) in three sample wells and one coastal point. The analysis incorporated calculations of water volume changes, flushing rates, and regression analysis between water volume changes and water quality parameters to assess the dynamics of groundwater quality fluctuations. Water level changes showed a 27-minute lag after tidal shifts, with well 1 showing dominant volume changes during ebb tide (65%), while wells 2 and 3 were dominant during flood tide. Well 2 showed higher susceptibility to quality changes due to its lower flushing rate (13.7%) compared to well 1 (56.6%). Statistical analysis revealed that water volume increases did not significantly influence water quality changes (p > 0.05). These findings enhance our understanding of groundwater dynamics in volcanic islands and suggest that factors beyond water volume changes should be considered when managing groundwater resources in these settings. The research provides valuable insights for developing effective water resource management strategies in similar geological contexts worldwide.

Kegiatan pengabdian kepada masyarakat dengan tema “Peningkatan Kapasitas Masyarakat Melalui Budidaya Ikan Sistem Bioflok” dilaksanakan di Desa Ake Dotilou, Kecamatan Oba Tengah, bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam budidaya ikan yang efisien dan berkelanjutan. Sistem bioflok dipilih karena teknologi ini memanfaatkan mikroorganisme untuk mengubah limbah menjadi sumber nutrisi tambahan bagi ikan, sehingga mendukung produktivitas budidaya dengan biaya yang lebih rendah dan ramah lingkungan. Kegiatan ini melibatkan pemberian materi dan diskusi interaktif. Hasil dari kegiatan menunjukkan peningkatan pemahaman masyarakat mengenai konsep dan penerapan sistem bioflok. Peserta secara aktif berdiskusi tentang kendala yang mereka hadapi, seperti manajemen kualitas air dan penggunaan pakan, serta solusi praktis yang ditawarkan oleh teknologi bioflok. Selain itu, pelatihan ini membuka wawasan masyarakat terhadap diversifikasi budidaya, termasuk potensi ikan lele dan komoditas lain yang sesuai dengan kondisi lokal. Kegiatan ini juga memotivasi masyarakat untuk memanfaatkan potensi sumber daya air di desa untuk mendukung keberhasilan budidaya. Selain itu, pemateri juga memaparkan peluang budidaya udang vaname menggunakan sistem bioflok, menekankan manfaat ekonomi dan tantangan teknis yang harus diatasi. Kegiatan ini diharapkan dapat menjadi langkah awal dalam mendorong penerapan teknologi bioflok secara luas, meningkatkan produksi perikanan, serta mendukung kesejahteraan masyarakat Desa Ake Dotilou secara berkelanjutan.

Selected as the National Fish Reserve (LIN), Maluku Province is known for its abundant marine resources and enormous fishery potential, supported by a capture fishery area of 658,294.69 km² which is the largest in Indonesia. Maluku has three Fishery Management Areas of the Republic of Indonesia (WPPNRI), namely WPPNRI-714, WPPNRI-715, and WPPNRI-718. However, based on production data for the capture fishery and aquaculture sectors in Maluku Province during the 2018-2022 period, these resource potentials have not been optimally utilized. Therefore, this research aims to analyze the ecological conditions and utilization of fishery resources in Maluku Province as a consideration for developing targeted policies and strategies for fishery resource utilization. This research uses a quantitative descriptive approach with data presented in narrative format, simple tables, graphs, and Multidimensional Scaling (MDS) analysis. Data collection was conducted from various sources over a 5-year period (2018-2022). Based on the analysis results, the status of ecological conditions and fishery resource utilization in Maluku Province is classified as less sustainable, indicated by Rapfish scores below 50. To improve the sustainability of fishery resource management in this region, strengthening of monitoring systems and community education about the importance of aquatic ecosystem conservation is needed.

Kegiatan pengabdian kepada Masyarakat, bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat khususnya kelompok pembudidaya ikan dan udang tentang budidaya ikan yang efisien dan berkelanjutan. S metode kegiatan pengabdian yaitu dengan memberikan materi dan diskusi aktif dengan peserta kegiatan, materi yang diberikan yaitu budidaya ikan dan udang dengan sistem bioflok. Sistem bioflok dipilih karena memiliki keuntungan dapat menghemat pakan karena mengandung protein dan lemak yang dapat dikonsumsi ikan sebagai tambahan nutrisi. Mengurangi pencemaran air karena limbah organik diubah menjadi biomassa dan sangat efisien dalam pemggunaan air karena tidak perlu sering mengganti air, cocok untuk daerah dengan keterbatasan air dan bisa digunakan dalam kepadatan tinggi karena kualitas air lebih stabil. metode kegiatan ini yaitu pemberian materi dan diskusi interaktif. Hasil dari kegiatan menunjukkan peningkatan pemahaman mereka mengenai konsep dan penerapan sistem bioflok. Peserta secara aktif berdiskusi tentang permasalahan yang mereka hadapi, seperti manajemen kualitas air dan penggunaan pakan, serta solusi praktis yang ditawarkan oleh teknologi bioflok. Kegiatan ini juga memotivasi kelompok pembudidaya ikan dan udang untuk memanfaatkan potensi sumber daya di desa untuk mendukung keberhasilan budidaya. Kegiatan ini diharapkan dapat menjadi langkah awal dalam mendorong penerapan teknologi bioflok secara luas, meningkatkan produksi perikanan, serta mendukung kesejahteraan masyarakat Desa Tuada secara berkelanjutan.
