Abstract

Perubahan iklim dan kurangnya teknologi penyimpanan dingin menjadi tantangan besar bagi nelayan tradisional Indonesia dalam menjaga kualitas tangkapan mereka. Penggunaan blok es sebagai metode pendinginan konvensional memiliki banyak keterbatasan, termasuk efisiensi rendah, durasi pendinginan terbatas, dan tuntutan logistik yang tinggi. Studi ini bertujuan untuk mengevaluasi kinerja sistem pendinginan berbasis termoelektrik Peltier yang diterapkan pada kotak pendingin berkapasitas 170-liter melalui pemodelan dan simulasi menggunakan perangkat lunak MATLAB dan CFD ANSYS Fluent. Proses penelitian meliputi perancangan model geometri kotak pendingin dan unit Peltier, melakukan simulasi awal di MATLAB Simscape untuk mengevaluasi kinerja termoelektrik, serta menganalisis distribusi suhu melalui simulasi aliran panas dan fluida dalam keadaan steady-state menggunakan ANSYS. Hasil menunjukkan bahwa sisi dingin Peltier dapat mencapai 274,85 K atau 1,7 °C pada arus 15 A, sementara sisi panas mencapai 323,8 K atau 50,65 °C. Distribusi suhu di dalam kotak pendingin menunjukkan kinerja pendinginan yang efektif pada periode 90 menit, terutama ketika setengah volume internal diisi dengan air. Dengan setengah volumenya diisi dengan air, suhu yang terukur sekitar 283,66 K atau 10,512°C, sedangkan untuk distribusi beban penuh, suhunya 285,13 K atau 11,98°C. Studi ini menyimpulkan bahwa simulasi terintegrasi MATLAB dan Ansys mampu memprediksi kinerja termal listrik Peltier, dan menunjukkan bahwa sistem pendingin berbasis Peltier dapat berfungsi sebagai solusi teknologi ramah lingkungan dan efisien energi yang sesuai untuk pendinginan penyimpanan ikan kecil di kapal penangkap ikan tradisional.

Climate change and the lack of cold storage technology pose major challenges for traditional Indonesian fishermen in preserving the quality of their catch. The use of ice blocks as a conventional cooling method has many limitations, including low efficiency, limited cooling duration, and high logistical demands. This study aims to evaluate the performance of a thermoelectric Peltier-based cooling system applied to a 170-liter cooling box through modeling and simulation using MATLAB and CFD software ANSYS Fluent. The research process includes designing the geometry model of the cooling box and Peltier unit, conducting an initial simulation in MATLAB Simscape to assess thermoelectric performance, and analyzing temperature distribution through steady-state thermal and fluid flow simulations using ANSYS. The results show that the cold side of the Peltier can reach 274.85 K or 1.7 °C at 15 A current, while the hot side reaches 323.8 K or 50.65 °C. The temperature distribution inside the cooling box indicates effective cooling performance at 90-minute period, especially when half of the internal volume is filled with water, with half of its volume filled with water showed temperatures around 283.66 K or 10.512°C and for distribution full load is 285.13 K or 11.98 °C. This study concludes that the MATLAB and Ansys coupled simulation are capable to predict the Peltier’s thermal electric performance and it shows that Peltier based cooling system a Peltier-based cooling system can serve as an environmentally friendly and energy-efficient appropriate technology solution for cooling of small fish cold storage onboard traditional fishing boat.
