Abstract

Penelitian ini berfokus pada penggunaan campuran bahan alami sebagai insulasi pada dinding palka ikan. Tujuan penelitian ini adalah mendesain komposisi dinding palka ikan dengan lapisan insulasi berbahan campuran polyurethane dan sabut kelapa dan menganalisa distribusi suhu pada dinding palka serta menganalisa suhu pendinginan di dalam ruang palka ikan. Metode yang digunakan adalah metode numerik berupa simulasi FEM (Finite Element Method) untuk melihat distribusi suhu pada dinding dan simulasi CFD (Computational Fluid Dynamics) untuk melihat distribusi fluida dan ikan di ruang palka. Simulasi FEM dilakukan sebanyak 4 variasi yaitu polyurethane 100%, polyurethane 90% dan sabut kelapa 10%, polyurethane 80% dan sabut kelapa 20%, dan polyurethane 70% dan sabut kelapa 30%. Simulasi CFD dilakukan sebanyak 3 variasi yaitu ruang palka kosong, ruang palka berisi chilled water, dan ruang palka berisi chilled water dan ikan. Metode analisis data dilakukan dengan membandingkan data antara hasil simulasi dengan hasil perhitungan. Hasil simulasi FEM menunjukkan bahwa dinding palka dengan insulasi dari campuran polyurethane 90% dan sabut kelapa 10% dipilih sebagai desain dinding terbaik dengan suhu minimum yang didapatkan paling rendah yaitu bernilai -8,5265e-14°C. Hasil simulasi CDF menunjukkan terjadinya kenaikan suhu pada chilled water yang bermula bernilai 1,259°C kemudian menjadi 3,5°C ketika ditambahkan ikan dan suhu ikan menjadi 2,2°C. Perbandingan antara hasil simulasi dengan hasil perhitungan memiliki perbedaan. Data hasil simulasi memiliki nilai yang lebih rendah dari hasil perhitungan sehingga dapat dikatakan bahwa metode simulasi terbilang lebih akurat jika dibandingkan dengan metode perhitungan manual.

This research focuses on using natural materials as insulation on the walls of fish hold. The purpose of this study was to design the composition of the fish hold wall with an insulating layer made from a mixture of polyurethane and coconut fiber and analyze the temperature distribution on the hatch wall and cooling temperature in the fish hold. The method used is a numerical method in the form of FEM (Finite Element Method) simulation to see the temperature distribution on the walls and CFD (Computational Fluid Dynamics) simulation to see the distribution of fluids and fish in the hold. The FEM simulation was carried out in 4 variations, namely 100% polyurethane, 90% polyurethane and 10% coconut fiber, 80% polyurethane and 20% coconut fiber, and 70% polyurethane and 30% coconut fiber. The CFD simulation was carried out in 3 variations: an empty hold, hold with chilled water, and a hold with chilled water and fish. The data analysis method is done by comparing the data between the simulation results and the calculation results. FEM simulation results show that the hatch wall with insulation from a mixture of 90% polyurethane and 10% coconut fiber was chosen as the best wall design with the lowest minimum temperature obtained, which is -8.5265e-14°C. The results of the CDF simulation show an increase in the temperature of the chilled water which starts at 1,259°C then becomes 3,5°C when fish is added, and the fish temperature becomes 2.2°C. There is a difference between the simulation results and the calculation results. The data from the simulation results have a lower value than the calculation results, so it can be said that the simulation method is more accurate than the manual calculation method.
