Abstract
Penelitian ini mengembangkan refrigerated-container loading problem (R-CLP) model untuk produk perikanan dengan mempertimbangkan distribusi temperatur internal. Model ini mempertimbangkan temperatur optimal produk perikanan dan distribusi temperatur internal kontainer berpendingin untuk memuat kargo produk perikanan ke dalam kontainer berpendingin dengan penurunan kualitas yang minimum. Tujuan model ini adalah untuk meminimasi total biaya yang terdiri dari biaya penalti, biaya penurunan kualitas, biaya pendingin, dan biaya tetap dengan memenuhi batas kualitas dari pelanggan. Algoritma model ini mengikuti metode constructive heuristics dengan pendekatan wall-building. Pendekatan yang dilakukan juga mempertimbangkan batasan pemuatan kargo (loading constraint) yang digunakan dalam implementasi nyata, antara lain batas berat, tumpukan, dan stabilitas vertikal. Simulasi computational fluid dynamics (CFD) dilakukan untuk mendapatkan data distribusi temperatur sebagai parameter untuk batasan distribusi temperatur internal. Model yang dikembangkan dapat digunakan untuk eksperimentasi dengan berbagai macam tipe produk perikanan, dimensi kargo, dan data distribusi temperatur. Hasil eksperimentasi pada penelitian ini menunjukkan signifikansi batas kualitas dari pelanggan, temperatur atur, dan kecepatan udara dingin pada biaya total. Perbandingan antara R-CLP dengan general container loading problem menunjukkan kemampuan model untuk meminimasi penurunan kualitas dan memunculkan tradeoff dengan volume utilisasi kontainer berpendingin, biaya penalti kargo yang gagal termuat, dan biaya tetap kontainer berpendingin.

This research aims to develop refrigerated-container loading problem (R-CLP) model for fishery products considering internal temperature distribution. The model considers the optimal temperature of fishery products and internal temperature distribution of refrigerated containers to pack fishery products cargo boxes into refrigerated containers with minimum quality loss. The objective of the developed model is to minimize total cost which consists of penalty cost, quality loss cost, refrigeration cost, and fixed cost with fulfilled quality requirement. The algorithm of the model follows constructive heuristics method based on the wall-building approach. The approach includes real practical loading constraints, such as weight limit, stacking, and vertical stability. Computational fluid dynamics (CFD) simulation is performed to obtain temperature distribution data as the parameter for the internal temperature distribution constraint. The developed model can be used for experimentation with various type of fishery products, cargo box dimensions, and temperature distribution data. The numerical experiments result of this research shows significant effect of quality requirement, temperature setting, and cold air velocity to total cost. The comparison between R-CLP with general container loading problem shows the model’s ability to minimize quality loss while also cause tradeoff with reefer volume utilization, penalty cost, and reefer fixed cost.
