The aim of this research is to identify changes in net geometry and analyze the correlation between the physical properties of the net and the geometry of the net that has been used for 1 to 3 years. The research used an experimental method by directly measuring the geometry of the net, namely mesh size, net diameter and knot height. The research also analyzed data on breaking strength and net elongation which were correlated with net geometry. The condition of the net when tested was dry. There were 4 treatments used in the research, namely control nets, nets that had been used by fishermen for 1, 2 and 3 years. The results of the research stated that the highest average gillnet mesh size value was for the 2 year net treatment and the lowest was 3 years. The highest average value of net diameter was the 1 year net and the lowest was the 2 year net. Meanwhile, the highest average gillnet node height is 1 year and the lowest is 3 years. The correlation value of net geometry with breaking strength has varying values. Breaking strength is closely related to the height of the knots in the mesh with a positive value of 0.77, whereas for mesh elongation all the mesh geometry indicators have negative values, so each increase in the mesh geometry value will decrease the elongation value.

Wilayah Pengelolaan Perikanan Negara Republik Indonesia atau sering disingkat dengan WPP NRI merupakan wilayah pengelolaan perikanan untuk penangkapan ikan, konservasi, penelitian, dan pengembangan perikanan yang meliputi perairan pedalaman, perairan kepulauan, laut teritorial, zona tambahan, dan zona ekonomi ekslusif Indonesia (ZEEI). Setiap tahun Pemerintah Indonesia mengalami kerugian yang besar akibat pencurian ikan dibeberapa wilayah di WPP 711, salah satu permasalahan disebabkan oleh belum terpilihnya satuan kerja utama di WPP 711, memilih satuan kerja utama tidaklah mudah karena harus mempertimbangkan banyak kriteria sehingga Kementrian Kelautan dan Perikanan dalam mengambil keputusan harus melalui perhitungan dan pemikiran jangka panjang agar keputusan yang diambil tidak salah, maka diperlukan suatu sistem pendukung keputusan yang dapat memperhitungkan segala kriteria yang mendukung pengambilan keputusan dalam menentukan wilayah satuan kerja utama di WPP 711. Metode yang digunakan dalan mengambil keputusan adalah AHP (Analytical Hierarcy Process) dan TOPSIS (Technique For Order Preference by Similarity to Ideal Solution). Dengan menggunakan metode tersebut, maka diperoleh wilayah satuan kerja utama dari beberapa kriteria (Daerah perbatasan, potensi sumber daya ikan, alur laut international, fasilitas & sarana prasarana, jumlah armada, penegakan hokum) adalah Satker Pontianak (0.780), Satker Natuna (0.778) dan Satker Batam (0.769). Hasil perangkingan tersebut akan dijadikan acuan sebagai dasar penentuan strategi peningkatan pengawasan wilayah perikanan di WPP 711 sehingga mampu meminimalisasi kerugian Negara akibat pencurian SDA di wilayah WPP 711 Indonesia.

Research related to the influence of facilities on the quality of fish landed and auctioned has been done previously, but the catches under this study are still limited to large pelagic fish with complex fish auction facilities. This study was conducted for small pelagic fish where the handling facilities at this location are still very limited. Therefore, survey research with purpose to analyze the effect of handling facilities (ships, fish auction sites, baskets) on the quality of small pelagic fish. The data taken is daily data with the method of observation at the location on the ship, fish auction place, and baskets. The species that taken were Eleutheronema tetradactylum, Ilisha elongate, Pampus argenteus, and Johnius trachychepalus. Each species consists of 5 individuals. Its tests was done by looking at the organoleptic and pH values. The tests were done to every species of fish. The pH value was obtained by testing the fish meat sample on the meat pH meter, while the organoleptic value was obtained by looking at the physical condition of the fish using a score sheet of fresh fish quality parameters. Then after the results are obtained, an analysis is carried out to determine the magnitude of facility influence on fish quality by simple linear regression analysis. The organoleptic values of four kinds of samples were on average 6.84 - 4.95, while the pH values measured in these fish ranged from 6.3 - 5.94. The effect of fish handling facilities on the organoleptic value is 82% compared to other factors. The fish quality as measured by the organoleptic test showed a fairly good quality, while measured by the pH test showed good results. Handling facilities do not greatly affect the quality of fish and there are other factors that can affect the decline in fish quality other than facilities. The relationship between fish handling facilities and quality can give an overview of the contribution of handling facilities to fish quality.Keywords:Fish auction marketFish qualityHandling facilities

This study was conducted to analyze the catches of sharks, such as composition, length-weight relationship, and to determine the distribution of shark fishing areas. Every fishing activity has by-catch issues. Fishers commonly catch sharks as by-catch. These fishing activities will harm the shark ecosystem in the waters. This research was conducted in March – May 2021 at PPS Cilacap. The results of this study showed that A. superciliosus (paitan shark) was a common catches and its total catch was 1,820 kg. The next common catch was Carcharhinus falciformis and the total catch was 723 kg. The lowest catch was the Carcharhinus sorrah shark (sorrah shark) and its total catch was 16 kg. The growth of Carcharhinus falciformis was negative allometric because b-value <3. Meanwhile, the growth of A. superciliosus is positive allometric because b-value was > 3. Length-weight relationship of Carcharhinus falciformis and A. superciliosus was isometric, which means that the growth between length and weight is balanced. Shark fishing areas are located at coordinates 8º - 15º South and 100º - 111º East. The area of shark fishing is at coordinates 8º - 10º South and 108º - 110º East.

Even though the government has established regulations regarding wages, the reality is that the wages received by crew members of fishing vessels are still not in accordance with regulations. Therefore, the purpose of this study is to identify the distribution of wages on purse seine vessels and to find out the gap between the wages received by crew. To achieve this goal, this study uses catch data for three fishing trips from March to May 2022, as well as crew wages from selling catches on the purse seine vessel PT Hasil Laut Sejati. The secondary data used is the productivity of the annual catch of purse seine vessels as well as supporting data from references related to the topics discussed. The data obtained were then analyzed using descriptive analysis, income analysis, and gap analysis. The average wage received by purse seine vessels crew is around Rp. 677,649.67 Rp. 1,190,134.00, the wages received are far below the City Minimum Wage, with a gap of 71.57% - 83.81%. The wages of Batam City purse seine crew are not in accordance with the City Minimum Wage of Batam City. Economic conditions and wages for crew members significantly require crew to continue working, to make ends meet.Keywords:CatchCrewIncome

Setiap operasi penangkapan ikan tidak terlepas dari proses manajemen yang dilakukan secara bertahap mulai dari perencanaan (planning), pengorganisasian (organizing), pelaksanaan (actuating) dan pengendalian (controlling) agar ketercapaian penangkapan ikan dapat dipenuhi. Purse seine merupakan alat tangkap yang menghasilkan produksi perikanan yang paling tinggi di PPS Nizam Zachman Jakarta. Kajian mengenai proses manajemen operasi penangkapan masih terbatas sehingga perlu dilakukan kajian mengenai manajemen operasional penangkapan pada KM. Mekar Kencana 03 di PPS Nizam Zachman Jakarta. Pengumpulan data dilakukan dengan observasi kegiatan penangkapan ikan di KM. Mekar Kencana 03 dan wawancara. Analisis data yang digunakan adalah analisis deskriptif kualitatif. Persiapan keberangkatan dilakukan 30 menit sebelum keberangkatan. Jumlah anak buah kapal saat melakukan penangkapan di laut minimal sebanyak 32 orang termasuk nakhoda. Perbekalan disiapkan sesuai dengan jumlah awak kapal. Kondisi kapal harus dipantau seperti mesin induk dan mesin gardan. Dokumen perizinan kapal harus disiapkan, pengecekan alat tangkap dan pengecekan alat navigasi kapal juga dilakukan. Pengawasan operasi penangkapan dilakukan langsung oleh pemilik kapal yang berperan sebagai nakhoda kapal. Kata kunci: manajemen, operasional, purse seine, PPS Nizam Zachman
