Abstract

Indonesia has abundant fisheries potency, one of fisheries potency in Indian Ocean is tuna fish. Primary productivity data used as indicator of tuna fisheries potency in Idian Ocean.Research location is in Indian Ocean 070 - 210 S and 1070 - 1210 E. Weekly satellite data in 2007 used are chlorophyl, sea surface temperature, Photosynthetic Available Radiation (PAR) and euphotic zone (Zeu) data. Daily fisheries data is from tuna fish catching data 2007 in PT. Perikanan Samudera Besar (PT. PSB). Satellite data is processed by Vertically Generalized Production Model (VGPM) formula to obtained primary productivity. Tuna fish catching data correlated to satellite data to know correlation of primary productivity value to fish catching data.Result of this research is there four species of tuna fish catch in Indian Ocean, that are Madidihang or Yellowfin tuna (Thunnus albacores), Bigeye tuna (Thunnus obesus), Southtern Bluefin tuna (Thunnus macoyii), and Albacore (Thunnus alalunga). Where 73% tuna fish is Bigeye tuna. Bigeye, Albacore and Yellowfin tuna are produced annually, while Southern Bluefin tuna in northwest monsoon is no fish production. Chlorophyll-a, sea surface temperature and primary productivity value in research location are from 0,06 mg/m3 to 0,38 mg/m3, from 24,640C to 31,820C, and from 73,22mgC/m2 to 658,57 mgC/m2 respectively. Coefficient correlation in primary productivity and fish catching in fishing ground area is small (r = 0.008), its explained that, fish catching number is not influenced by primary productivity. In high or low primary productivity condition tuna fish catched in Indian Ocean area. Potential fishing ground area of Bigeye tuna, Albacore, Yellowfin and Southern Bluefin tuna in Indian Ocean are in 110 – 160 S and 1060 – 1210 E, the primary productivity value is from 73 mgC/m2day to 732 mgC/m2day and differences of sea surface temperature value of tuna fish are from 240 C to 310 C, 240 C to 300 C, and 250 C to 310 C for Bigeye tuna, Albacore and Yellowfin tuna, respectively. While Southern Bluefin tuna distribution is in temperature area from 260 C to 300 C and primary productivity value is from 92 mgC/m2day to 449 mgC/m2day

Abstract

Pemberdayaan masyarakat nelayan payang di Palabuhanratu sangat dibutuhkan untuk mendapatkan solusi permasalahan terhadap produktivitas alat tangkap payang yang semakin rendah, terutama saat musim paceklik dan musim ikan sedang. Kegiatan ini bertujuan untuk mendeskripsikan kondisi nelayan payang, mengukur faktor teknis perikanan payang dan memberikan rekomendasi strategi pemberdayaan masyarakat. Metode yang digunakan dengan melakukan FGD, sosialisasi aspek IPTEKs dan uji coba penggunaan inovasi teknologi rumpon booster protein hewani pada kapal payang. Pengumpulan data dilakukan pada bulan November – Desember 2023 dengan teknik wawancara terhadap 20 nelayan pemilik kapal dan 20 nelayan ABK. Uji coba penangkapan ikan dilakukan sebanyak 10 trip dengan kapal payang perlakuan dan kontrol di Teluk Palabuhanratu. Hasil kegiatan menunjukkan bahwa nilai skor faktor teknis yang diperoleh nelayan pemilik kapal sebesar 1,60 dan nelayan ABK sebesar 1,33 dengan rata-rata sebesar 1,50. Atribut yang paling rentan bagi nelayan pemilik kapal adalah alat bantu penangkapan sebesar 1,00. Hasil tangkapan ikan pelajis banyak diperoleh pada kapal payang perlakuan, karena pengaruh dari penggunaan rumpon booster protein hewani yang menyebabkan ikan-ikan berlimpah di permukaan air. Kapal-kapal payang kontrol bila tidak mendapatkan kemunculan ikan di permukaan air, maka kapal payang akan di arahkan ke perairan yang lebih dangkal untuk mendapatkan jenis ikan demersal, seperti eteman dan ikan layur. Pola berburu ikan pada operasi siang hari akan mengakibatkan penggunaan BBM yang cukup besar karena tidak ada kemunculan ikan di permukaan. Dengan demikian, penggunaan alat bantu penangkapan ikan yang disebut dengan rumpon booster protein hewani dibutuhkan oleh kapal payang operasi siang hari.

Abstract

The community empowerment program for the fishermen who are members of KUB Berkah Sagara aims to disseminate the innovation of frozen bait booster and 2-deck krendet trap technology as additional fishing gear in their fishing operations. The activities were carried out at Loji Village and the IPB Palabuhanratu Marine Field Station. Activities were carried out using FGD methods, interviews, technical training and trials of catching crustaceans. The KUB Berkah Sagara Partner Fishermen are between 30 and 59 years of age and have with a formal education level between elementary and vocational/high school. Skills fishing have been passed down from generation to generation and they are not yet aware of the innovation of the 2-deck krendet trap and the frozen bait booster innovation. After the training activities, the fishermen finally understood the 2-deck krendet trap and frozen bait booster innovation. Fishermen carry out trial activities to catch crustaceans alternately on each trip. The 2-door 2-deck krendet trap provides a higher catch of crustaceans in term of the number of tails and weight compared to traditional, 1-door and 3-door of 2-deck krendet trap. The average distribution of crustaceans caught in 2-deck krendet trap was more than 70% in the bottom trap and <30% in the upper trap. The use of a 2-door of 2-deck krendet trap should be operated with a single buoy colony system with a ratio between the number of 2-deck krendet traps and the number of frozen bait boosters of 5:1, where the frozen bait booster is placed in a collapsible trap and the 2-deck krendet trap uses trash fish bait, such as sardine or pony fish.
