This study aims to analyze the catch of Sondong as the main information in managing fishing, the availability of data and information about the productivity of Sondong fishing gear fisheries in Selat Akar Village and with the management in the utilization of fish resources, the sustainability of Sondong fishing business can be maintained. The research method used in this research is a survey method used to obtain the necessary data directly from the research site. The results showed that the production of Sondong ship fluctuated. The results showed that the production of Sondong ship fluctuated. So that the annual production value of Sondong ship for 5 years also fluctuates. The productivity value of Sondong ships varies where the highest values in 2017 and 2019 show that the period was a good year in producing fishing using these fishing gear. The low productivity in 2018 was due to temporary weather anomalies, where weather conditions worsened which affected the success of the capture process. and the lowest was in 2020. And the results of the Trend of Sondong fishing gear production show that there is a high correlation that indicates that produce results in the next 3 years will increase and show that the initial production value of sondong fishing gear is relatively high.

Artificial live rock is an artificial live rock that is shaped like living rock in nature. Artificial live rock is designed to mimic natural living rock which is capable of being a substrate for corals, a habitat for epibenthic and the biological filter of a saltwater aquarium. The purpose of this research is to know the technique of making artificial live rock and the development of artificial live rock that are suitable for export on an export scale. The method used in this research is an experimental method with quantitative descriptive analysis. The level of suitability and product standards uses a simultaneous regression coefficient test analysis or the F test. The manufacture of artificial live rock does not have a special pattern, but artificial live rock is made as attractive as possible and resembles the shape in nature. Product standardization is carried out by using artificial live rock materials consisting of: 1 kg of pumice stone, ½ kg of cement, ½ kg of sand, 500 grams of calcium and 1.5 liters of water. The type of substrate that is good and ideal for algae on the surface of artificial live rock is an area with a bottom of coral sand mixed with coral rubble. Artificial live rock can be harvested for 3 months in water, with the characteristics of the surface of the artificial live rock covered algae which is then cleaned and placed in a treatment pond before being exported

Microplastics originated from degraded plastic materials that may be flown to water bodies and accidentally swallowed by aquatic organisms. The research aims to understand the microplastics in the water body in the Lubuk Siam lake and was conducted from September to November 2020. Samplings were conducted 3 times, once per month, in 3 sampling points. At each sampling point, 100 L of water was taken and filtered using a plankton net (30 µm mesh size). To obtain the microplastics, the filtered water was again filtered using Whatman filter paper No.42, and the type of microplastics was identified using a binocular microscope. Results show the types of microplastics found in the water namely fibers, films, and fragments. The microplastic density was (10 fibers/m3), (93 films/m3) and (40 fragments/m3) in the water. Data obtained indicate that the most common type of microplastic found in the waters was film.

Penggunaan rumpon dapat membantu nelayan mengurangi konsumsi bahan bakar, mempercepat penentuan daerah tangkapan, mempersingkat jumlah hari operasi keseluruhan, dan mengurangi biaya operasional. Namun dampak negatif juga timbul seperti konflik dengan nelayan lain dan potensi terjadinya penangkapan yang berlebih. Kementerian Kelautan dan Perikanan telah mengeluarkan peraturan terkait penggunaan rumpon untuk mencegah timbulnya dampak negatif. Peraturan tersebut akan berhasil bila berjalan dan dipatuhi oleh nelayan yang menjadi tujuan peraturan tersebut. Namun saat ini tidak diketahui apakah nelayan di Pelabuhanratu mengetahui, memahami, dan menaati peraturan tersebut. Oleh sebab itu, penelitian ini bertujuan untuk menemukan tingkat kepatuhan nelayan Pelabuhanratu terhadap aturan formal dari pemerintah maupun aturan informal di kalangan mereka sendiri. Penelitian dilakukan melalui wawancara dengan pemilik modal, nakhoda, dan anak buah kapal. Waktu penelitian adalah Agustus-Oktober 2017. Analisis terhadap hasil wawancara dilakukan secara deskriptif dan dilengkapi dengan analisis Likert. Hasil penelitian menunjukkan bahwa pemilik modal mengetahui dan memahami peraturan yang ada tetapi tidak mematuhinya. Nakhoda dan anak buah kapal menjalankan sendiri etika sosial diantara mereka untuk saling menghormati rumpon milik orang lain, sanksi pencurian dan tanggungjawab terhadap rumpon, namun tidak memperhatikan adanya peraturan formal dari pemerintah.

Pancing ulur tuna di Indonesia merupakan perikanan skala kecil dan umumnya tidak dilengkapi dengan alat untuk menarik pancing. Hal ini seringkali menyebabkan nelayan menghadapi berbagai permasalahan seperti beban kerja yang berlebihan dan penurunan kualitas hasil tangkapan saat pancing dimakan oleh ikan tuna yang relatif besar (>10 kg). Penelitian ini memiliki tujuan akhir yaitu untuk membuat suatu alat kejut listrik yang siap digunakan oleh nelayan pancing ulur ikan tuna. Penelitian ini merupakan penelitian awal yang bertujuan menentukan daftar kebutuhan komponen dan membuat sebuah rancang bangun alat kejut listrik. Metode yang digunakan adalah studi literatur dan eksperimen. Hasil penelitian penentuan daftar kebutuhan komponen menunjukkan bahwa jenis kejut listrik DC digunakan sebagai penyetrum ikan. Sementara itu untuk sistem saklar menggunakan timer delay relay. Selanjutnya berdasarkan hasil perhitungan pemilihan bahan menunjukkan bahwa stainless steel menjadi prioritas pertama dengan nilai C sebesar 1. Bentuk tabung dipilih sebagai desain bentuk utama karena memiliki kecepatan dan waktu tempuh tercepat dibandingkan bentuk lainnya, yaitu 2,84 m/detik dan 35,27 detik. Konstruksi untuk merakit satu unit alat kejut listrik membutuhkan setidaknya 26 komponen. Hasil penelitian pembuatan prototipe yang telah dibuat memiliki dimensi berdiameter 6 cm dan tinggi total 40 cm serta berat prototipe 2,67 kg.
