Abstract

ABSTRAK Mikroorganisme memegang peran penting dalam ekosistem perairan sebagai agen utama dalam proses dekomposisi, siklus nutrien, dan simbiosis. Studi ini bertujuan mengidentifikasi dan menganalisis faktor biotik dan abiotik yang memengaruhi kelangsungan hidup mikroba di lingkungan perairan. Metode yang digunakan adalah studi literatur yang memfokuskan pada parameter lingkungan seperti suhu, pH, salinitas, oksigen terlarut (DO), BOD, COD, serta interaksi antar mikroorganisme dan organisme akuatik lain. Hasil analisis menunjukkan bahwa keseimbangan faktor abiotik dan biotik sangat menentukan struktur dan fungsi komunitas mikroba. Perubahan lingkungan seperti peningkatan suhu, pencemaran, dan eutrofikasi berpotensi mengganggu stabilitas mikroba dan ekosistem perairan secara keseluruhan. Studi ini memberikan landasan ilmiah dalam pengelolaan kualitas air dan konservasi ekosistem perairan. Kata kunci : Ekosistem perairan, Faktor abiotic, Faktor biotik, Kelangsungan hidup mikroba, Mikroorganisme akuatik.
PENGARUH JUMLAH MATA PANCING LONGLINE TERHADAP HASIL TANGKAPAN IKAN TUNA SIRIP KUNING (Thunnus albacares) Zebua, Nistiarni; Halawa, Vince Kurniawan; Zebua, Ratna Dewi; Telaumbanua, Betzy Victor; Laoli, Destriman; Sanora Laia, Dian Agung

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengkaji pengaruh jumlah mata pancing pada alat tangkap longline terhadap hasil tangkapan ikan tuna sirip kuning (Thunnus albacares) melalui pendekatan tinjauan pustaka. Data diperoleh dari berbagai literatur ilmiah yang relevan dan dianalisis secara deskriptif untuk memahami hubungan antara jumlah mata pancing, efisiensi operasional, serta faktor lingkungan terhadap produktivitas tangkapan. Hasil kajian menunjukkan bahwa peningkatan jumlah mata pancing, khususnya hingga 1592 unit, secara signifikan meningkatkan hasil tangkapan dibandingkan jumlah yang lebih rendah. Namun demikian, penggunaan jumlah mata pancing yang berlebihan dapat menurunkan efisiensi dan meningkatkan risiko overfishing serta tangkapan sampingan (by-catch). Faktor-faktor lain seperti suhu, salinitas, arus laut, serta kemampuan operasional kapal turut memengaruhi keberhasilan penangkapan. Oleh karena itu, pengelolaan jumlah mata pancing harus mempertimbangkan aspek teknis, ekologis, dan keberlanjutan sumber daya ikan tuna. Temuan ini diharapkan dapat menjadi dasar bagi pengambilan keputusan dalam pengelolaan alat tangkap longline yang lebih efektif, efisien, dan berkelanjutan. Kata kunci: longline, mata pancing, tuna sirip kuning, hasil tangkapan, keberlanjutan.

Abstract

Aquaculture plays a vital role in meeting the global demand for animal protein, yet the dependency on expensive imported feed ingredients remains a significant challenge. Optimizing the use of local feed ingredients is a strategic approach to enhance sustainability and cost-efficiency in fish farming. This research aims to optimize the composition of local feed ingredients to achieve 30% protein content in farmed fish feed. The formulation involves rice bran, corn bran, fish meal, and tofu dregs, selected based on local availability and protein content. The methodology includes analysis of the protein content of raw materials, formulation testing, and physical evaluation of feed. The results show that the pellets produced have nutritional quality that meets the target, good physical stability, and cost efficiency of up to 40% compared to commercial feed. This research makes a significant contribution in supporting the sustainability of the fish farming industry and reducing dependence on imported raw materials.

Abstract

Fishing ports play a crucial role in supporting the sustainability and efficiency of the fisheries system, starting from the process of landing catches to distribution and marketing. This study aims to analyze the impact of fishing port location selection on operational efficiency and sustainability of fisheries resources in Indonesia, using a literature study approach. The results of the study show that proper site selection can reduce logistics costs, improve market access, and encourage coastal economic growth. Conversely, inappropriate locations have the potential to create operational bottlenecks, environmental pollution, and social conflicts. Factors such as water depth, accessibility, environmental conditions, and the involvement of local communities need to be considered comprehensively. An ecosystem-based and participatory approach is key in ensuring that the port built is able to support environmental sustainability and community welfare. Therefore, planning the location of fishing ports should involve multidisciplinary studies that integrate technical, social, environmental, and regulatory aspects to produce effective, inclusive, and sustainable development decisions.

Abstract

fishing activities, especially in islands with limited accessibility such as Tello Island, South Nias Regency. This study aims to analyze the function, role, and development potential of Tello Island Fishing Port in order to strengthen the local fishing sector. The method used is a literature study with a qualitative descriptive approach through secondary data review and field observation. The results show that this port functions as a fish landing center for local fishermen, but various important facilities such as the Fish Auction Site (TPI), cold storage, and fish processing units are severely damaged and have not been repaired. The available ice storage is also unable to meet the daily needs of fishermen. Based on these findings, it can be concluded that the development of the fishing port on Tello Island is urgently needed through the improvement of post-harvest facilities, increased storage capacity, and the empowerment of the fishing community. It is recommended that the local government and relevant stakeholders immediately revitalize the port infrastructure to support the sustainability of fisheries and improve the economy of coastal communities.
