Abstract

Occupational Health and Safety (OHS) in the fishing industry is often overlooked, despite the extremely high potential for work-related accidents. This study aims to analyze the risks during the post-harvest process of shark fins at Tanjung Luar Fishing Port and UD Mamenasae using the Hazard and Operability Study (HAZOP) method. The results indicate that nearly all activities, especially cargo hold unloading, transfer, transport, identification, shark cutting, and fin drying, have a high-risk potential for accidents such as falls/slips, musculoskeletal complaints, cuts, and sunburn. Some processes, including transportation to collectors, storage, sorting, and packaging, carry a moderate risk of concussion or respiratory disorders. Furthermore, all stages present a low risk of bacterial infectious diseases. The primary hazards identified include slippery floors, non-ergonomic work postures, sharp objects, the absence of Personal Protective Equipment (PPE), sun exposure, and a lack of railings. As a mitigative measure, temporary actions such as improved hygiene, provision of PPE, ergonomic improvements, and education are highly recommended to reduce potential hazards and enhance workplace safety. Key words: HAZOP, occupational safety, post-harvest, risk analysis, shark fin

Abstract

Potensi ikan layang di perairan Kepulauan Kei menunjukan peluang signifikan sebagai sumberdaya perikanan bernilai ekonomi tinggi dengan metode penangkapan menggunakan alat tangkap pukat cincin, bagan dan pancing tonda. Purseine memungkinkan penangkapan dalam jumlah besar secara efisien, sedangkan bagan dan pancing tonda memberikan alternatif bagi nelayan dengan tingkat selektifitas yang berbeda. Meskipun potensi tangkapan cukup besar, eksploitasi berlebihan dapat mengancam kelestarian stok ikan layang dan ekosistem laut setempat. Oleh karena itu, keberlanjutan sumber daya ikan layang perlu dipertimbangkan. Penelitian ini bertujuan menganalisis pola pertumbuhan, faktor kondisi, dan tingkat penangkapan perikanan ikan layang yang didaratkan di Ohoi Sathean,  Selayar, Namar, Dian Pulau, Dunwahan, Ohoiren, Mastur dan Banda ely di Kepulauan Kei dari Desember 2023 hingga Mei 2024. Data primer dikumpulkan melalui survei lapangan dengan pengamatan langsung  terhadap 502 ekor sampel secara acak, data sekunder mengenai hasil tangkapan dan usaha penangkapan selama lima tahun terakhir dikumpulkan dari nelayan melalui wawancara dengan Teknik purposive sampling. Analisis meliputi distribusi panjang ikan, hubungan panjang-berat (nilai b = 2,36 menunjukan pertumbuhan alometrik negatif), faktor kondisi (K = 1,00–1,08 menandakan kondisi fisiologis kurang optimal), tingkat penangkapan serta daerah penangkapan. Tingkat penangkapan tertinggi ditemukan pada pukat cincin dengan fluktuasi selama 6 tahun terakhir, bagan dan pancing tonda relatif stabil. Hubungan upaya penangkapan terhadap tingkat penanngkapan menghasilkan nilai determinasi (R²) = 0,5275 dengan persamaan regresi Tingkat Penangkapan (CPUE) = 2332,8 - 0,5098E, yang menunjukkan hubungan negatif antara peningkatan upaya tangkap dengan hasil per unit usaha. Temuan ini menjadi dasar ilmiah untuk kebijakan pengelolaan perikanan layang berkelanjutan di Kepulauan Kei.

Abstract

Respons fisiologi mata ikan selar (Selaroides leptolepis) dan ikan kembung (Rastroliger brachysoma) berbeda untuk setiap warna cahaya. Respons fisiologi mata ikan bisa dijadikan indikator dalam menentukan tingkat ketertarikan ikan terhadap warna cahaya tertentu. Penelitian ini bertujuan untuk mengidentifikasi tingkat ketertarikan ikan selar dan ikan kembung terhadap cahaya warna putih, kuning, hijau dan biru. Metode penelitian menggunakan metode percobaan yang dilakukan di bagan tancap. Sepuluh ekor ikan selar dan ikan kembung yang dibatasi dengan jaring diberi cahaya selama 30 menit. Sampel ikan yang telah diberi perlakuan cahaya diambil matanya dan dilakukan analisis histologi. Analisis data yang digunakan dalam penelitian ini adalah analisis regresi ukuran ikan, indeks sel kon dan kecepatan pergerakan sel kon. Hasil penelitian menunjukkan bahwa ikan selar sangat tertarik terhadap cahaya LED warna hijau dan biru, sedangkan ikan kembung tertarik terhadap cahaya warna biru. Rata-rata indeks sel kon ikan selar pada cahaya warna biru dan hijau adalah 77,3±7,4% dan 70,7±6,8%, sedangkan rata-rata indeks sel kon ikan kembung yang diberi cahaya warna biru adalah 79,9±2,0%. Kecepatan rata-rata pergerakan sel kon ikan selar yang diberi cahaya biru mencapai 0,0180±0,0028 μm/det, sedangkan ikan kembung dengan cahaya hijau adalah 0,0157±0,0018 μm/det. Berdasarkan hasil penelitian dapat disimpulkan bahwa ikan selar sangat tertarik terhadap cahaya warna hijau dan biru, sedangkan ikan kembung sangat tertarik terhadap cahaya warna biru.

Abstract

The blue swimming crab (Portunus pelagicus) is a high economic importance marine species and serves as a primary target for local fisheries employing collapsible traps in Gebang Mekar, Cirebon Regency waters. This study aimed to examine the sex ratio and growth pattern based on variations in carapace width and body weight of crabs captured in the area. Fieldwork was conducted from April to May 2023 in Gebang Mekar Village. Data collection involved measuring the carapace width and body weight of crabs obtained from 30 fishing trips. A total of 2,191 individuals were recorded, comprising 638 males (29.2%) and 1,553 females (70.8%), resulting in a male-to-female ratio of 1:2.4. Carapace width ranged from 6 to 16 cm, while body weight varied between 21 to 338 grams. The analysis of the width-weight relationship yielded a regression coefficient (b) of 2.923, indicating a negative allometric growth pattern, where carapace width increases faster than body weight. The results also demonstrated a positive correlation between carapace width and body weight, suggesting that larger individuals tend to be heavier. Key words: blue swimming crab, carapace width and weight, sex ratio

Abstract

Squid jigging fisheries in Indonesia have developed rapidly, leading to a substantial increase in energy consumption due to the growing number of squid jigging units. Traditionally, metal halide (MH) lamps with electrical power ranging from 24 to 30 kW are used as light attractors. This study aimed to design a LED (light-emitting diode) lamp for squid fishing with a light distribution pattern comparable to that of MH lamps and to evaluate its fuel consumption. The research involved the design and construction of an LED-based squid lamp, measurement of light intensity in air, and comparison of fuel consumption between LED and MH lamps under laboratory conditions. Underwater light intensity was measured in the waters of Banten Bay. The electronic system employed components with total LED power of 450 watts. Results showed that the average light intensity of the LED lamp decreased by only 10.57% compared to the MH lamp. The Specific Fuel Consumption (SFC) of MH lamps ranged from 0.00162–0.00176 kg/hp·h, while that of LED lamps ranged from 0.00109–0.00119 kg/hp·h. The LED system achieved a fuel efficiency of 40.54%, indicating a 19.03% improvement compared MH lamps. Further field-scale experiments are required to validate effectiveness in actual squid fishing operations. Key words: intensity, light, measurement, squid

Abstract

Blue swimming crab (Portunus pelagicus) is the dominant catch in Betahwalang, Demak, and the most important export fish commodity, particularly to USA. The high demand for this crab has been promoting an excessive fishing effort, causing a decrease in the crab's natural stock. This study aims to investigate the biological condition of P. pelagicus on the northern coast of Central Java and assess the crab stock exploitation status in this study area. Carapace width, body weight, Gonad Maturity Stages (GMS), and sex of crab samples were collected from the fishers and collectors landing sites or meeting points. This study employs a simple random sampling technique with no replacement. This study revealed that the maximum carapace width of female crabs was 56-164 mm, and the estimated carapace width at first maturity (Lm) was 98.2 mm. The relationships between carapace width and body weight between male and female crabs indicated positive and negative allometric growth patterns. During this assessment, the P. pelagicus stock indicated an 'over-exploited status, with an LB-SPR parameter of 19 percent and an exploitation rate (E) of 0.66. Management measures such as minimum legal size, reduced effort, and open-close areas and seasons should be implemented to achieve sustainable use of the crab fishery.Keywords:Blue swimming crabFishing gearDemak watersCarapace lengthSpawning potential ratio
