Sungai Tumapel di Malang digunakan oleh masyarakat untuk berbagai aktivitas sehari-hari sehingga berpotensi menurunkan kualitas air. Penelitian ini bertujuan menilai kondiai kualitas air sungai Tumapel menggunakan metode Biotilik dan FBI. Metode eksploratif digunakan dengan pengambilan sampel di empat stasiun pengmatan sebanyak 5 kali ulangan, dan analisis biologis menggunakan indeks Biotilik dan FBI. Hasil penelitian menunjukkan bahwa kedua metode biologis tersebut sama-sama menunjukkan bahwa air Sungai Tumapel telah tercemar. Aliran sungai pada kawasan Riparian alami menunjukan kondisai kualitas air tercemar sedang. Tercemar berat pada kawasan Pertanian dan pemukiman. Sedangkan untuk aliran sungai pada kawasan Peternakan Kualitas air tercemar sangat berat. Penelitian ini merekomendasikan pemantauan rutin kualitas air, peningkatan metode Biotilik dengan melibatkan akademisi, identifikasi sumber pencemaran, edukasi masyarakat, dan pengelolaan sungai secara berkelanjutan.

The existence of marine fish in Indonesian waters is very abundant and will continue to provide benefits as long as it is managed properly. Marine fish that act as a source of animal protein can be utilized through the fishing process. The agriculture, forestry, and fisheries sectors are the main pillars of GDP at 23.01 percent. The East Coast region contributed the most, namely 74.73% or around 717.04 trillion rupiah to the GDP of North Sumatra. Bagan Percut is one of the potential areas in North Sumatra for efforts to develop the non-port fisheries subsector. Therefore, the social capital of fishing fishermen to be able to realize food security at the local level is important to be studied. This study aims to analyze the role of capture fisheries in realizing food security with sociological theory. This research uses a qualitative approach. The results showed that capture fisheries play a role in realizing food security in three pillars, namely availability, affordability, and utilization. Fishermen play an important role in fish production, agents play a role in distributing catches, and households play a role in food utilization. During the lean season, fishing households can maintain food security by utilizing social capital through the Serikat Tolong Menolong (STM), officers, and cooperatives. In conclusion, from the economic side, capture fisheries contribute to regional income and fishermen's source of income. From the social side, fishermen and agents/distributors must have social capital to support capture fisheries activities in realizing food security.

This study aimed to evaluate the effectiveness of using surround nets in increasing the catch of male mackerel in Siofabanua Village, North Nias Regency. In an effort to overcome the low catch of conventional methods, this study investigated the technical and environmental factors that influence the success of surround nets. The research method used a descriptive qualitative approach with field observations, in-depth interviews with fishermen, as well as the study of relevant documents. The results showed that the use of circle nets significantly increased the number and quality of catches, as well as the time and labor efficiency of fishers. The main factors influencing the successful use of circle nets are the condition of the net, placement techniques, and environmental factors such as water depth, food sources, and underwater habitat structure around Siofabanua Village. In addition, weather and seasonal factors also impact catch success. Recommendations include improving net specifications, providing technical training to fishers, and developing policies and regulations that support sustainable fisheries. In conclusion, the use of circle nets has the potential to be an effective and environmentally friendly technology in increasing the productivity of local fisheries in Siofabanua Village, as well as supporting sustainable fisheries practices and marine resource conservation
