Abstract

Sektor perikanan Indonesia sebagian besar dilayani oleh kapal-kapal tradisional skala kecil di bawah 5 Gross Tonnage (GT), yang banyak di antaranya mengandalkan mesin diesel yang berkontribusi signifikan terhadap degradasi lingkungan. Kehilangan ikan pasca panen (PHFL) masih menjadi masalah kritis, dengan kerugian diperkirakan mencapai 20–30% dari total tangkapan, yang menyebabkan dampak ekonomi dan gizi yang substansial. Metode pengawetan konvensional, seperti penyimpanan es dan pendinginan kompresi uap, dibatasi oleh iklim tropis Indonesia dan kendala energi kapal penangkap ikan kecil. Penelitian ini menyelidiki penerapan sistem pendingin termoelektrik Peltier sebagai alternatif berkelanjutan untuk pengawetan ikan pada kapal-kapal kecil. Sistem ini menggunakan 20 modul Peltier TEC-12715 yang dipasang pada kotak pendingin Styrofoam 170 liter, dengan pelat aluminium (36×29 cm) sebagai media pendingin. Modul didistribusikan secara merata di kedua sisi kotak (10 per sisi) dan didukung oleh heat sink dan kipas untuk pembuangan panas. Ada tiga variasi percobaan—tanpa beban, setengah beban, dan beban penuh. Kotak pendingin mencapai suhu udara 8,6°C selama percobaan tanpa beban, suhu air 5,1°C selama percobaan dengan beban setengah, dan suhu air 5,8°C selama percobaan dengan beban penuh dalam waktu 120 menit. Koefisien kinerja rata-rata (COP) di semua percobaan adalah 0,9. Penelitian ini menunjukkan bahwa sistem pendingin berbasis Peltier, jika dipadukan dengan insulasi yang efektif dan material yang ringan, menawarkan solusi praktis dan hemat energi untuk mengurangi PHFL, meningkatkan kualitas ikan, dan mendukung keberlanjutan perikanan skala kecil di Indonesia.

Indonesia’s fisheries sector is predominantly served by traditional, small-scale vessels under 5 Gross Tonnage (GT), many of which rely on diesel engines that contribute significantly to environmental degradation. Post-harvest fish loss (PHFL) remains a critical issue, with losses estimated at 20–30% of the total catch, leading to substantial economic and nutritional impacts. Conventional preservation methods, such as ice storage and vapor-compression refrigeration, are limited by Indonesia’s tropical climate and the energy constraints of small fishing boats. This research investigates the application of a Peltier thermoelectric cooling system as a sustainable alternative for fish preservation on small vessels. The system uses 20 TEC-12715 Peltier modules installed on a 170-liter Styrofoam cooling box, with aluminum plates (36×29 cm) as the cooling medium. Modules are distributed evenly on both sides of the box (10 per side) and supported by heat sinks and fans for heat dissipation. There are three experiment variations—no load, half load, and full load. The cooling box achieved air temperatures of 8.6°C during no load experiment, 5.1°C water temperature during half load experiment, and 5.8°C water temperature during full load experiment within 120 minutes. The average coefficient of performance (COP) across all experiment was 0.88. The research shows that Peltier-based cooling systems, when paired with effective insulation and lightweight materials, offer a practical and energy-efficient solution to reduce PHFL, improve fish quality, and support the sustainability of Indonesia’s small-scale fisheries.
