Abstract

Indonesia merupakan negara kepulauan terbesar di dunia dengan luas wilayah laut yang dapat dikelola sebesar 5,8 juta km2 yang memiliki keanekaragaman sumberdaya kelautan dan perikanan yang sangat besar. Di kota Surabaya, jumlah nelayan yang mewakili perikanan tangkap memiliki jumlah jauh diatas angka 2000. Hal tersebut menunjukkan bahwa perikanan tangkap memiliki potensi yang besar sebagai sumber mata pencaharian penduduk Kota Surabaya. Penelitian ini bertujuan untuk mengetahui efektivitas alat pemanggil ikan berbasis gelombang bunyi pada jaring insang permukaan yang dioperasikan pada waktu berbeda. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian kunatitatif dengan menggunakan metode eksperimen yang terdiri dari 2 perlakuan dan 16 ulangan. Analisa data dilakukan dengan uji normalitas dan uji homogenitas kemudian dilanjut uji T. Hasil penelitian ini didapatkan bahwa efektivitas alat pemanggil ikan berbasis gelombang bunyi pada jaring insang permukaan yang dioperasikan pada waktu berbeda terbaik didapat pada pagi hari dengan nilai sebesar 1,099 gram. Sehingga hasil tangkapan terbaik didapat pada pagi hari, yakni sebesar 1,099 gram. Dari hasil penelitian tersebut disarankan agar pengoperasian jaring insang yang dilengkapi dengan alat pemanggil ikan berbasis gelombang bunyi, dilaksanakan pada pagi hari saat suhu air masih rendah.

Abstract

This study aims to determine the type and composition of the catch, as well as describe the operation of the sondong fishing gear (push net) in the waters of the Rupat Strait, Dumai City, Riau Province. The method used is a descriptive method with quantitative and qualitative approaches. Data collection was carried out through direct observation, interviews with fishermen from KM Camar Laut, and documentation of catches from January to June 2025. The results of the study indicate that the sondong fishing gear has a simple construction with high effectiveness in catching white shrimp (Penaeus sp) as the main catch. In addition, there are bycatch in the form of senangin fish, gulama fish, sole fish, flatfish, black pomfret, swimming crab, sea eel, and tiger shrimp. The discarded catch that has no economic value is dominated by puffer fish (Tetraodon sp). Of the total catch of ±2,437 kg, approximately 43.4% is the main catch, 25.2% is bycatch, and 31.4% is discarded. Although effective, this tool is considered less selective and has the potential to damage the waters bottom. Therefore, sustainable management and monitoring of the use of sondong fishing gear is needed so as not to threaten the sustainability of the marine ecosystem in the area.

Abstract

Penelitian ini bertujuan mengevaluasi penerapan sistem Hazard Analysis and Critical Control Point (HACCP) pada perusahaan pengalengan rajungan, berdasarkan Peraturan BKIPM Nomor 32 Tahun 2023. Metode yang digunakan adalah benchmarking model Standard vs. Actual Performance untuk mengidentifikasi kesenjangan antara standar dan implementasi aktual. Hasil penelitian menunjukkan kesenjangan pada deskripsi produk yang belum mencantumkan karakteristik mikrobiologi, kimia, dan fisika, serta batasan bahaya yang tidak dijelaskan secara rinci. Kelompok pengguna belum menyebutkan kelompok rentan, dan tidak terdapat label alergen pada kemasan produk. Diagram alir proses juga tidak sesuai dengan praktik di lapangan akibat kerusakan mesin pengering. Penyebab kesenjangan antara lain kebiasaan tim HACCP menggunakan dokumen lama yang dianggap masih relevan, kurangnya pemahaman teknis, serta dominasi buyer dalam desain kemasan yang menyebabkan minimnya pencantuman informasi wajib seperti label alergen. Solusi yang diusulkan meliputi pembaruan dokumen HACCP, revisi diagram alir, penyesuaian label sesuai standar, serta pelatihan rutin dan audit internal berkala untuk memperkuat penerapan HACCP di perusahaan.
PENGARUH JENIS MEREK DAGANG ARTEMIA YANG BERBEDA TERHADAP HATCHING RATE DALAM PROSES DEKAPSULASI PADA SALINITAS 30 PPT Ramadhan, Rinto Fajar; Subagio, Hari; Rosana, Nurul; Trisyani, Ninis

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh jenis merek dagang artemia terhadap daya tetas (hatching rate) setelah proses dekapsulasi pada salinitas 30 ppt. Artemia merupakan pakan alami penting dalam tahap larva budidaya ikan dan udang karena nilai nutrisinya yang tinggi (Istiqomah et al., 2024). Metode eksperimen yang digunakan melibatkan empat jenis merek dagang artemia (A, B, C, dan D) dengan lima ulangan dalam Rancangan Acak Lengkap. Hasil menunjukkan bahwa terdapat perbedaan signifikan antar perlakuan (p < 0,05). Merek A menunjukkan daya tetas tertinggi (72,1%), sementara C terendah (57,2%). Faktor-faktor yang berperan termasuk spesies artemia, kualitas kista, efektivitas dekapsulasi, serta stabilitas kualitas media seperti suhu, salinitas, oksigen terlarut, dan pH. Temuan ini dapat menjadi acuan pemilihan artemia untuk hatchery guna meningkatkan efisiensi produksi larva.

Abstract

The Bahari 64 fishermen group located in Bulak District, Surabaya City is one of the fishermen groups fostered by the Faculty of Engineering and Marine Sciences, Hang Tuah University. As a form of concern for the community in introducing current developments in renewable technology and a form of the Faculty of Engineering and Marine Sciences' commitment to Community Service, it is necessary to conduct socialization and technological counseling to fishermen, in this case the 64 Bahari fishermen group. Android-based technology, modern materials and knowledge related to ship stability and ship repair technology are some of the information conveyed through the Focus Group Discussion between the 64 Bahari Fishermen Group and the Faculty of Engineering and Marine Sciences. The activities carried out are expected to have a positive impact and be directly beneficial to the community, especially those who work as fishermen

Abstract

Vannamei shrimp (Litopenaeus vannamei) is a leading aquaculture commodity in Indonesia, with high market demand for both domestic consumption and export. However, cultivation continues to fail, primarily due to water quality problems. Water-quality parameters play a crucial role in the ecosystem of intensive shrimp ponds. This study aimed to determine the effect of stocking density on water quality and production outcomes. The research was conducted over one shrimp culture cycle at PT Shihe Udang Industry Indonesia. The results showed that the water-quality dynamics in all three observed ponds tended to increase as the day of culture progressed, and the parameters that most strongly influenced shrimp growth and production were NH4⁺, total organic matter, and total Vibrio count. The data indicate that higher stocking densities strongly affect water quality: Pond A1 (361 shrimp/m²) had more stable water quality than ponds A5 (637 shrimp/m²) and C (1,296 shrimp/m²). Production in Pond A1 was the most optimal at 11,220.31 kg, with a survival rate of 68% and a feed conversion ratio of 1.47. The lowest production occurred in Pond C at 1,484.56 kg, with a survival rate of 25% and a feed conversion ratio of 2.43. The poor production performance in Pond C was driven by the very high stocking density, which deteriorated water quality; the high total Vibrio count also contributed to shrimp mortality.
