STATUS ALAT TANGKAP JARING KEJER DI CIREBON, JAWA BARAT
Get PDFKegiatan penangkapan ikan dengan menggunakan berbagai jenis alat tangkap yang dilakukan terus-menerus akan mempengaruhi kondisi sumberdaya ikan dan lingkungan. Penangkapan ikan dengan metode tidak ramah lingkungan akan mempercepat terjadinya over fishing karena kegiatan penangkapan yang semakin tidak selektif dan terjadinya kerusakan habitat sebagai akibat dari metode penangkapan yang merusak. Namun penangkapan legal juga tetap menyebabkan over fishing jika penerapan effort dilakukan melebihi kapasitas yang mungkin bagi stok sumber daya dalam melakukan pemulihan. Penggunaan alat tangkap ramah lingkungan berbasis Code of Conduct for Responsible Fisheries (CCRF) merupakan salah satu langkah dalam menjaga keberlangsungan kegiatan penangkapan ikan yang tetap memperhatikan sumberdaya ikan dan lingkungan. Terdapat berbagai jenis alat tangkap yang digunakan nelayan di wilayah Cirebon, salah satunya yaitu jaring kejer (bottom gill net). Tingginya tingkat operasi penangkapan ikan tradisional di sekitar perairan pantai Cirebon diduga mempengaruhi ketersediaan stok sumberdaya ikan. Tujuan penelitian yaitu menentukan status alat penangkapan ikan jaring kejer ramah lingkungan di perairan Cirebon. Penelitian dilakukan pada bulan Februari – April 2020 di Kabupaten Cirebon. Metode penelitian yang digunakan yaitu metode deskriptif. Analisis data Jaring Kejer ramah lingkungan menggunakan metode pembobotan (Scoring method) berdasarkan 9 kriteria alat tangkap ramah lingkungan. Pada penelitian ini diambil sebanyak 13 sampel unit alat penangkapan ikan. Hasil penelitian menunjukan alat tangkap jaring kejer yang digunakan nelayan di Cirebon Jawa Barat termasuk kedalam kategori alat tangkap ramah lingkungan dengan skor 30,38

PENGEMBANGAN DESAIN PINTU MASUK BUBU LIPAT BERDASARKAN ASPEK TINGKAH LAKU RAJUNGAN: Development of Collapsible Trap Entrance Design Based on Blue Swimming Crabs Behavior
No full textBlue swimming crab fishing using collapsible traps is widely used by fishermen because its caught live crabs and high selectivity. However, the passive fishing operation causes its low fishing productivity. The success of crabs fishing using folding traps is influenced by the suitability of the entrance design used. The size of the net and the inclination angle that are not by the crab\u27s behavior will cause the crab to fail to be caught. This study aims to determine the more effective entrance design for catching crabs using the collapsible trap. The study was conducted in a laboratory using three mesh sizes, including 1.00, 1.25, and 1.50 inches with 30°, 40°, and 50° inclination angles. Each treatment combination uses different individual crabs. The study was conducted at night in an aquarium equipped with an infrared camera. Differences in mesh size and angle of inclination affect the crab\u27s success rate and crawling speed in crossing the net field. The results showed that the highest percentage of crabs that successfully crossed the net field was obtained using a 1.25-inch mesh with an angle of 40°. The highest average crawling speed was also obtained at the same mesh size and angle of inclination. The use of a 1.25-inch mesh with an angle of 40° is expected to increase the effectiveness of catching crabs with folding traps
The Purse Seine Fleet Compliance strategy to Fishing Regulations at Nizam Zachman Fishing Port, Jakarta: STRATEGI PENINGKATAN KEPATUHAN ARMADA PURSE SEINE TERHADAP REGULASI PENANGKAPAN IKAN DI PPS NIZAM ZACHMAN JAKARTA
No full textImporter countries of Indonesian fishery products, such as European Union countries (EU) and the United States (USA), are very concerned about the treacebility of fishery products, which lead to some rejection of fishery products obtained from illegal, unreported and unregulated activities (IUU Fishing) in NZFPJ. Approximately 231 vessels, 121 of it are purseiners, conducted fishing operations outside permitted fishing areas and at least 42 vessels were moored outside their assigned fishing ports. Considering the number of violations, this study is aiming at formulating strategies to improve compliance level of fishing vessels. Data from the case study were analyzed using Strengths Opportunities Weaknesses Threats (SWOT) method and Quantitative Strategic Planning Management (QSPM). The results showed that strategies to improve the compliance of purseiners to fishing regulations in NZFPJ are by developing an integrated fishing vessel monitoring system with relevant agencies conducting law enforcement in the field of marine and fishery. In addition, reward and punishment scheme along with education for fishermen and businessmen are required to improve awareness. Lastly, there is need to provide facilities and training to support the monitoring activities.

The Impact Study of Re-Measurement of Fishing Vessels Based at Tumumpa Coastal Fishing Port
No full textPhysical inspection of fishing vessels is part of the flow applied by the Directorate General of Capture Fisheries to verify and confirm the congruence of the actual dimension of the fishing vessel with the official document of fishing license. This inspection includes the calculation of the vessel size measured in Gross Tonnage (GT) which determine the amount of fishery retribution paid as Non-Tax State Revenue (PNBP) in the capture fisheries sector. The purpose of this study is to examine the size discrepancy due to mark down practices by re-measurement and to calculate PNBP based on mooring services at Tumumpa Coastal Fishing Port, Manado. A comparison method using a t-test is applied to investigate the difference between two measurements. Based on the test, there is a significant difference between written and actual measurements of GT which affects PNBP.

The Economies of Scale and Efficiency of Small-Scale Capture Fisheries in Kurau Village, Central Bangka District
Get PDFThis study investigates the economies of scale and efficiency of small-scale capture fisheries, as well as to know how the socio-economic variable influencing the small-scale capture fisheries business in the Kurau village, Central Bangka district. The approach used is a quantitative method by applying multiple linear regression models to adopt the Cobb-Douglas production function. The study found that the scale-economies condition in the small-scale fisheries is decreasing return to scale. We also found the results of allocative efficiency in this small-scale fisheries business are relatively inefficient. Other findings of model estimation indicated that the variables of capital, labor, and fishing distance have a positive and significant effect, while the variables of age, experience, and education level of fishermen have no significant effect on small-scale fisheries production. The main factor that is an obstacle for local fishermen is technology, therefore technology assistance and support from the government are needed as a policy to improve small-scale capture fisheries business and fishermen welfare

UKURAN LAYAK TANGKAP IKAN PELAGIS KECIL DI PERAIRAN KENDARI, SULAWESI TENGGARA
Get PDFThe small pelagic resources in the waters of Kendari (FMA 714) that are dominant are mackerel scad (Decapterus macarellus) and Indian mackerel (Rastrelliger kanagurta). Fishing in these waters uses a mini purse seine, with the production of 2 species of fish has reached 38.2% of the total allowed catch FMA 714. Because of intensive use, management needed to preserve resources. The purpose of this study is to determine the decent size based on a comparison of length of the first capture (Lc) and the length of first mature (Lm), and prediction of spawning season. Data collection was conducted by researchers and assisted by enumerators monthly. The results showed that the size of the mackerel scad in between 17.5 - 30.5 cm FL (n = 3207 tails). The size of the Indian mackerel found between 18.5 - 26.5 cm FL (n = 2556). The length at first captured of both species was larger than the size at first matured (Lm> Lc) so that the decent size is 23 cm FL for mackerel scad and 22 cm FL for Indian mackerel. The prediction of the spawning season in May-August can be the basis for closing the area during the spawning season.

ASPEK ERGONOMI AKTIVITAS PENANGKAPAN IKAN TUNA PADA KAPAL LONGLINE KM SATELIT, DI MUARA BARU, JAKARTA UTARA
Get PDFThis research was aiming at analysing ergonomic aspects and identifying potential hazards resulted from fishing activities. Data was collected from a long line fishing vessel MV Satelit. Analysis of ergonomic aspects focused on four major activities namely setting, drifting, hauling and fish handling. The investigation was conducted to examine the suitability of on board working area with fishermen’s movement. The result showed that on board working area was inadequate compared to fishermen’s movement because of limited zones for fishermen (ranged from 1 – 3 m2/ person) without any safety equipment. Based on Job Safety Analysis (JSA), it was revealed that there were 14 potential hazards emerging from fishing activities; 64,29% of them were moderate risk and the rest were trivial risk. However, fishermen have no significant efforts to prevent those hazards.
