Full text linkSalah satu pusat industri perikanan tangkap yang didominasi oleh perikanan skala kecil di Indonesia adalah Pelabuhan Ratu. Pelabuhan Ratu sebagai pusat kegiatan nelayan dan ekonomi perikanan Sukabumi-Jawa Barat. PPN Pelabuhan Ratu adalah salah satu fasilitas penting yang perlu dimanfaatkan dan dikelola agar dapat berkinerja dengan baik. Salah satu alat tangkap yang banyak digunakan oleh masyarakat Pelabuhan Ratu adalah alat tangkap payang. Pengoperasian alat tangkap payang memiliki tingkat ketidakpastian yang tinggi, sehingga termasuk ke dalam kategori usaha berisiko tinggi. Maka dari itu, tujuan dari riset ini adalah mengobservasi pengoperasian alat tangkap payang serta mengetahui komposisi hasil tangkapan utama dan sampingan, selektivitas dan keramah lingkungan alat tangkap bagan apung yang dioperasikan di PPN Pelabuhan Ratu. Hasil tangkapan dari payang adalah ikan semar dan ikan sekartaji. Komposisi masing-masing jenis tangkapan ikan semar (Mene maculata) dan ikan sekartaji (Scomberoides sp) berjumlah 85% dan 15%. Proporsi alat tangkap payang dapat dikategorikan sebagai ramah lingkungan jika dilihat dari segi proporsi hasil tangkapan. Sementara apabila dilihat dari tingkat kematangan gonad ikan hasil tangkapan, sebanyak 10 dari 17 (59%) ikan semar yang ditangkap masih memiliki panjang ikan di bawah ukuran matang gonad. Hal ini menjadi indikasi bahwa alat tangkap payang belum ramah lain lingkungan apabila ditinjau dari aspek kematangan gonad hasil tangkapan. Hasil selektivitas indeks keragaman (H’) Shannon mendapatkan nilai (H’) sebesar 0,022. Nilai H’ < 1 sehingga dapat disimpulkan bahwa tingkat keanekaragaman hasil tangkapan kapal payang di Pelabuhan Ratu rendah
DINAMIKA POPULASI DAN STATUS STOK IKAN TEMBANG PUTIH (Escualosa thoracata) DI PERAIRAN KABUPATEN CIREBON BERDASARKAN SPAWNING POTENTIAL RATIO
Full text linkThe white sardine (Escualosa thoracata) is an essential small pelagic species supporting coastal fisheries in Java's northern waters. This study evaluated the population dynamics and stock status of the species in the coastal waters of Cirebon Regency, using the Spawning Potential Ratio (SPR) as a biological indicator. Field sampling was carried out from December 2024 to August 2025 at principal fishing grounds near the estuaries of Bungko Lor and Cisanggarung. Length–weight data, size distribution, and gonadal maturity stages were analyzed to estimate growth parameters, mortality rates, and key size indicators (Lc₅₀% and Lm₅₀%). The SPR was determined using a length-based approach. The catch was dominated by individuals measuring 66–80 mm total length (TL), with the highest frequency in the 70–74 mm TL class. The length–weight relationship followed W = 0.0000436 L2.6497 (R² = 0.8433), indicating negative allometric growth. The first capture size (Lc₅₀%) was 71.0 mm TL, slightly smaller than the size at first sexual maturity (Lm₅₀%) of 73.0 mm TL. The von Bertalanffy growth parameters were L∞ = 96.08 mm TL and K = 1.60 yr⁻¹. The exploitation rate (E) reached 0.76, exceeding the optimal level (≈ 0.5), while the SPR was 19%, below the recommended biological threshold of 20% needed to sustain recruitment. The white sardine population in Cirebon coastal waters is under heavy fishing pressure, leading to reduced reproductive potential

Penelitian dilakukan di KKP Gili Matra pada bulan Agustus 2024 dengan menggunakan pendekatan kualitatif melalui pemanfaatan data primer dan sekunder. Data primer diperoleh melalui wawancara semi-terstruktur dan mendalam dengan aktor-aktor utama yang terlibat dalam pengelolaan dan pemanfaatan ruang laut, sedangkan data sekunder diperoleh melalui analisis substansi tiga peraturan utama: Peraturan Menteri Kelautan dan Perikanan No. 28 Tahun 2021 tentang Penyelenggaraan Penataan Ruang Laut, Keputusan menteri Kelautan dan Perikanan No. 34 Tahun 2022 tentang Penetapan KKP Gili Air, Gili Meno, dan Gili Trawangan, serta Keputusan Dirjen Pengelolaan Kelautan dan Ruang Laut No. 62 Tahun 2023 tentang Rencana Pengelolaan KKP Gili Matra Tahun 2023–2042. Analisis dilakukan menggunakan konsep rules-in-use dari Elinor Ostrom untuk menilai keselarasan antarperaturan dan efektivitas pengaturan kelembagaan. Hasil penelitian menunjukkan masih terdapat ketidaksinkronan antara substansi peraturan pemanfaatan ruang laut dan pengelolaan KKP Gili Matra, yang berdampak pada hambatan implementasi kegiatan ekowisata. Ketidaksinkronan tersebut disebabkan oleh lemahnya koordinasi dan penguatan kelembagaan antar-pemangku kepentingan, serta belum optimalnya integrasi antara regulasi dan kondisi sosial-ekologis masyarakat setempat.TITLE: MARINE SPATIAL UTILIZATION FOR ECOTOURISM BASED ON OSTROM’S RULES-IN USE IN GILI MATRA CONSERVATION AREAThis study aims to analyze the weaknesses and deficiencies in the substance of regulations governing marine spatial utilization and the management of the Gili Matra Island Conservation Area (KKP Gili Matra) in West Nusa Tenggara Province, within the context of institutional arrangements supporting sustainable ecotourism development. The research was conducted in the Gili Matra Conservation Area in August 2024, using a qualitative approach that combined primary and secondary data. Primary data were collected through semi-structured and in-depth interviews with key stakeholders involved in marine spatial utilization and conservation management, while secondary data were obtained through document analysis of three main regulations: the Minister of Marine Affairs and Fisheries Regulation No. 28 of 2021 on Marine Spatial Planning Implementation, the Ministerial Decree No. 34 of 2022 on the Establishment of the Gili Air, Gili Meno, and Gili Trawangan Conservation Area, and the Directorate General of Marine Spatial and Ocean Management Decree No. 62 of 2023 on the Management Plan of the Gili Matra Conservation Area 2023–2042. The analysis applied Elinor Ostrom’s rules-in-use framework to assess the coherence and institutional effectiveness of these regulations. The findings reveal inconsistencies between the regulatory frameworks of marine spatial utilization and conservation management, resulting in implementation challenges for ecotourism activities. These inconsistencies stem from weak institutional coordination among decision-makers and insufficient integration of regulatory instruments with local socio-ecological dynamics
