Tingginya permintaan tuna sirip kuning baik dalam memenuhi kebutuhan pasar mancanegara dan pasar lokal, berdampak pada keberlanjutan perikanan tuna tersebut. Wilayah perairan Flores Timur adalah salah satu lokasi migrasi bagi tuna sirip kuning; Kecamatan Larantuka merupakan tempat pendaratan terpenting bagi nelayan lokal handline tuna sirip kuning. Kegiatan perikanan tuna sirip kuning ini merupakan salah satu pendapatan utama bagi nelayan lokal dan pemerintah daerah setempat. Penelitian ini bertujuan untuk mengestimasi tingkat eksploitasi dan menganalisa rezim pemanfaatan dari perikanan handline tuna sirip kuning di Larantuka, Flores Timur. Model bioekonomi Fox dan Copes digunakan dalam penelitian untuk menganalisa tingkat lestari sumber daya tuna ekor kuning dari pendekatan input dan output. Hasil estimasi dari kedua model menunjukkan bahwa tingkat pemanfaatan sumber daya ikan tuna sirip kuning oleh nelayan lokal handline masih dalam zona lestari secara ekonomi dan ekologi. Maximum economic yield (MEY) merupakan strategi terbaik untuk mengelola keberlanjutan perikanan tuna sirip kuning di perairan Flores Timur. Melalui pengelolaan rezim MEY diperkirakan dapat menyerap tenaga kerja lebih dari 30 orang, peningkatan armada alat penangkapan sebanyak 25 unit dan pemasukan keuntungan secara ekonomi sebesar Rp68.123.060.000,00 per tahun.Title: Bioeconomic Analysis of Yellowfin Tuna Fishery in Larantuka of East Flores Regency, Indonesia The high demand for yellowfin tuna both in national and international markets has a consequence to the fish resources sustainability. Eastern Flores water is a major area of this tuna mobility; the district of Larantuka is the central port for local yellowfin tuna handline fisheries. These activities are substantial incomes for the local community and regional government. This study, therefore, aims to calculate fish exploitation level and to analyze appropriate management for yellowfin tuna fisheries in Larantuka, East Flores. The bioeconomics Fox and Copes models are used to evaluating the optimal fisheries from input and output approaches. The models’ applications demonstrated that yellowfin tuna handline fisheries are currently estimated sustainable both in ecology and economics. During the study period, the maximum economic yield (MEY) is a recommended strategy to manage yellowfin tuna fisheries in Larantuka, Eastern Flores. The strategy contributes to increasing the number of workers about 30 people, the number of fishing fleets about 25 units and reaching the economic rent  IDR 68.123.060.000,00 in a year

This research was conducted in the city of Bitung, North Sulawesi Province with activities centered on the Bitung Ocean Fisheries Port (PPS), which began from mid March to April 2019. The fishing activities studied are using the fishing areas around the waters of  North Sulawesi Province namely the Sulawesi Sea and The Maluku Sea which are included in WPP 715 and 716 based on tuna catch landed data on PPS Bitung. The purpose of this study was to analyze the value of sustainable potential by looking at the level of utilization and Maximum Sustainable Yield (MSY) of tuna in the waters around North Sulawesi Province based on a surplus production model approach (Schaefer Model). This research is expected to be used as a consideration in the management of tuna stocks around the waters of North Sulawesi Province, and can be used as a basis for further research. This study uses a secondary data collection method in the form of fishery statistics documents. The data used are data from tuna fishing and fishing (effort), from 2014 to 2018 (5 years). The results showed that the sustainable potential of tuna fisheries around the waters of North Sulawesi Province based on North Sulawesi PPS data indicated that, the sustainable potential value of tuna that could be caught was 14,173.51 tons / year which is counted as 80% of the value of tuna resources around the waters of North Sulawesi Province. PPS Bitung data which amounted to 17,716.15 tons / year for Hmsy, 1,200.15 trips / year for Emsy, with an average CPUE value of 2014-2018 of 19 tons / trip. The level of tuna utilization around the waters of North Sulawesi Province is based on data from PPS Bitung in 2014, 2017 and 2018 which indicate that there were indications of overfishing with the largest utilization rate in 2014 which reached a value of 155.09%.Keywords: tuna, Bitung, Bitung PPS, sustainable potential, MSY. ABSTRAKKegiatan penelitian ini berlangsung di Kota Bitung, Provinsi Sulawesi Utara dengan kegiatan berpusat di Pelabuhan Perikanan Samudera (PPS) Bitung, yang dimulai  dari pertengahan bulan Maret hingga bulan April 2019. Aktivitas perikanan tangkap yang ditelaah berlangsung di sekitar perairan Provinsi Sulawesi Utara yaitu Laut Sulawesi dan Laut Maluku yang masuk ke dalam WPP 715 dan 716 berdasarkan data tangkapan tuna yang didaratkan di PPS Bitung. Tujuan dari penelitian ini adalah untuk menganalisis nilai potensi lestari dengan melihat tingkat pemanfaatan dan maximum sustainable yield (MSY) ikan tuna di sekitar perairan Provinsi Sulawesi Utara berdasarkan pendekatan model produksi surplus (Model Schaefer). Penelitan ini diharapkan dapat digunakan sebagai bahan pertimbangan dalam pengelolaan stok ikan tuna di sekitar perairan Provinsi Sulawesi Utara, serta dapat digunakan sebagai dasar untuk penelitian selanjutnya.  Penelitian ini menggunakan metode pengumpulan data sekunder berbentuk dokumen. Data yang diambil adalah data tangkapan ikan tuna dan upaya penangkapan ikan atau effort (trip), dari tahun 2014 sampai dengan 2018 (5 Tahun). Hasil penelitian menunjukkan potensi lestari perikanan tuna di sekitar perairan Provinsi Sulawesi Utara berdasarkan data PPS Bitung Sulawesi Utara nilai potensi lestari tuna yang bisa ditangkap adalah 14.173,51 ton/tahun 80% dari nilai pemanfaatan sumber daya perikanan tangkap tuna di sekitar perairan Provinsi Sulawesi Utara berdasarkan data PPS Bitung yang sebesar 17.716,15 ton/tahun untuk Hmsy, 1.200,15 trip/tahun untuk Emsy, dengan nilai CPUE rata-rata tahun 2014-2018 sebesar 19 ton/trip. Tingkat pemanfaatan tuna di sekitar perairan Provinsi Sulawesi Utara berdasarkan data PPS Bitung Sulawesi Utara di tahun 2014,2017 dan 2018 sudah yang menandakan adanya indikasi overfishing dengan tingkat pemanfaatan terbesar di tahun 2014 yang mencapai nilai 155,09%.Kata Kunci: ikan tuna, Bitung, PPS Bitung, potensi lestari, MSY.

Abstract The model of the skipjack tuna resource management that can provide maximum rent can be done with a clear ownership regime (sole owner) or in the condition of MEY balance. However, the management and utilization of skipjack tuna resources must also consider the factors that can result in overfishing of both biological and economics overfishing. This study aims to assess the management and utilization of skipjack tuna fisheries resources in North Gorontalo Regency using a bioeconomic approach. Data processing is done by approaching the bioeconomic model using skipjack tuna fisheries biological and economic parameters. The results showed that the maximum rent obtained in skipjack fisheries in North Gorontalo Regency was at the MEY regime compared to the MSY and OA regime. However, based on the actual data obtained, it is known that the average production of skipjack tuna in North Gorontalo Regency has not reached the optimum catch value in the equilibrium condition of MSY (hMSY ), but in some period the actual catch value has passed the optimal catch value (hMSY ), this means that skipjack tuna has overfished (biological overfishing). While the actual production value of skipjack tuna catches in North Gorontalo Regency has passed the production of optimum MEY (hMEY ). This condition indicates that actually skipjack tuna resources have experienced an economic overfishing.
