Responden berjumlah 33 orang yang berasal dari pelaku usaha, peneliti dan akademisi, staf Dinas Perikanan Kota Tual dan penyuluh perikanan yang dipilih secara purposive sampling. Berdasarkan nilai indeks keberlanjutan, diperoleh bahwa status keberlanjutannya memang masih belum baik, 4 dimensi (57,17 untuk lingkungan; 52,89 untuk ekonomi; 54,29 untuk sosial; 55,13 untuk teknologi) dalam kategori cukup, dan 1 dimensi (44,89 untuk kelembagaan) dan 49,95 secara multidimensi masuk dalam kategori kurang. Semua atribut dimensi, berdasarkan kriterianya, menjadi faktor-faktor SWOT yang dianalisis lebih lanjut menggunakan Internal Factor Analysis Summary dan Eksternal Factor Analysis Summary (IFAS dan EFAS). Hasilnya, kegiatan usaha berada pada Kuadran II, sehingga strategi besarnya diversifikasi, yang dalam hal ini diartikan sebagai perubahan atau perluasan upaya. Formulasi strategi kemudian dilakukan melalui matriks SWOT, dan dihasilkan perubahan atau perluasan upaya pada perizinan, sarana penyimpanan, sarana pengasapan, dan pemasaran.Kata Kunci: Ikan Asap, Ikan Tongkol, RAPFISH, Strategi Keberlanjutan Usaha, SWOTABSTRACTThe business of the smoked mackerel tuna (Euthynnus affinis) on Dullah Island South of Tual City is not yet sustainable. This research aims to formulate a business sustainability strategy based on its dimensions. Strategy formulation is carried out through Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis, preceded by sustainability analysis by modification of the Rapid Appraisal for Fisheries (RAPFISH mod) with 5 dimensions and 20 attributes for each dimension. Respondents totaled 33 people from business actors, researchers and academics, Tual City Fisheries Service staff and fisheries extension servicers who were selected using purposive sampling. Based on the sustainability index values, it was found that the sustainability status is still not good, 4 dimensions (57.17 for environmental; 52.89 for economic; 54.29 for social; 55.13 for technology) are in the sufficient/enough category, and 1 dimension (44.89 for institutional) and 49.95 multidimensionally falls into the poor category. All dimensional attributes, based on the criteria, become SWOT factors which are analyzed further by Internal and External Factor Analysis Summary (IFAS and EFAS). As a result, business activities are in Quadrant II, so the grand strategy is diversification, which in this case is defined as changing or expanding efforts.

Harga ikan kurisi relatif terjangkau bagi masyarakat lokal ataupun internasional. Beralihnya masyarakat dari konsumsi daging merah ke ikan menyebabkan tingginya permintaan akan ketersediaan ikan kurisi. Peningkatan penangkapan ikan kurisi di Labuhan Maringgai menyebabkan diperlukannya langkah lebih lanjut terkait informasi aspek biologi ikan sehingga terbentuk pengelolaan perikanan yang berkelanjutan. Penelitian ini bertujuan untuk mengetahui pola pertumbuhan dan faktor kondisi ikan kurisi (Nemipterus japonicus) di Labuhan Maringgai, Lampung Timur. Pengambilan data dilakukan pada Bulan November 2023 – Januari 2024 dengan tiga kali pengamatan. Sebaran frekuensi panjang total ikan kurisi di Labuhan Maringgai memiliki kisaran panjang dan berat masing-masing 115 – 230 mm dan 18 – 159 g. Ukuran panjang ikan terbanyak berada pada selang kelas 147 – 162 mm. Hasil analisis panjang berat menunjukkan pola pertumbuhan ikan kurisi memiliki sifat alometrik negatif dengan persamaan W = 0.004 L1.89. Fungsi fisiologis ikan kurisi di perairan Labuhan Maringgai berada pada kondisi yang baik berdasarkan nilai rata-rata faktor kondisi (Kn) sebesar 1.06. Hal ini menjelaskan bahwa ekosistem perairan sebagai habitat ikan berada dalam keadaan baik yang dimungkinkan karena cukupnya ketersediaan makanan dan faktor abiotik lainnya.

The species is relatively affordable for local and international community. Switching from red meat to fish consumption has led to a high demand for the availability of this species. The increase in threadfin bream fishing has required further steps related to information on biological aspects of species to ensure a sustainable fisheries management. This study aims to determine the growth patterns and condition factors of Japanese threadfin bream. Data were collected in November 2023 to January 2024 with three observations. The species frequency distribution has a length and weight range of 115 – 230 mm and 18 – 159 g, respectively. Most of the fish lengths were in 147 to 162 mm class interval. The results of length-weight analysis show the growth pattern of the species has a negative allometric (W = 0.004 L1.89). The physiological function of the species is in good condition based on the average condition factor (Kn) of 1.06. This explains the aquatic ecosystem as a fish habitat is in good condition, which is possible due to the sufficient availability of food and other abiotic factors.Key words: condition factor, growth pattern, Japanese threadfin bream, Labuhan Maringgai","PeriodicalId":325230,"journal":{"name":"Juvenil:Jurnal Ilmiah Kelautan dan Perikanan","volume":"2 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140410572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in September 2023. The collection point consisted of 3 stations, and sampling was carried out at high tide with three repetitions. The filtering process uses a plankton net with a mesh size of 30 µm. Phytoplankton at the research location consists of five classes, namely Cyanophyceae, Euglenophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. Meanwhile, zooplankton consists of 7 groups consisting of Protozoa, Rotifera, Crustacea, Polychaeta, Gastropoda, Pelecypoda, and Nematoda. Phytoplankton has the highest percentage in the Bacillariophyceae class, reaching 71.7%, and the lowest 1% (Dinophyceae, Euglenophyceae, and Chlorophyceae). The abundance of phytoplankton at station three during the study ranged between 2,025,600 cells/m3 - 6,710,400 cells/m3 and zooplankton in the range of 23,400 ind/m3 - 33,480 ind/m3.
