Abstract
Buah dan sayur merupakan produk perishable yang kualitasnya akan menurun jika disimpan dalam waktu lama di tempat yang tidak tepat. Kontainer berpendingin atau reefer akan menjaga produk pada suhu rendah selama proses pengiriman. Kargo harus ditempatkan di area di dalam reefer yang suhunya mendekati suhu optimal untuk setiap produk. Penelitian ini akan mengembangkan model Refrigerated-Container Loading Problem (R-CLP) untuk kontainer berpendingin yang memuat kargo berventilasi untuk pengiriman buah dan sayur. Model akan dikembangkan menggunakan metode heuristik konstruktif dengan menggunakan pendekatan wall-building. Simulasi menggunakan Computational Fluid Dynamics (CFD) akan dilakukan untuk mendapatkan data distribusi suhu di dalam reefer. Tujuan dari penelitian ini adalah untuk menghasilkan suatu alat pendukung keputusan untuk mengoptimalkan hasil pertanian serta mengurangi food loss akibat proses distribusi. Hasil dari percobaan menunjukkan kemampuan model untuk meminimalkan biaya penurunan kualitas. Hasil percobaan juga menunjukkan penggunaan kargo berventilasi memberikan hasil yang lebih baik daripada kargo tertutup untuk memuat produk buah. Buah menghasilkan panas hasil respirasi yang harus dikeluarkan dari kargo. Lubang ventilasi kargo memfasilitasi udara dingin dari reefer masuk ke kargo dan udara panas dari buah keluar dari kargo. Diperlukan penurunan suhu sebesar 2°C saat menggunakan kargo tertutup untuk dapat menyesuaikan distribusi suhu mendekati suhu kargo terbuka

Fruits and vegetables is a perishable product that will decrease in quality if stored for a long time in an unsupportive place. Refrigerated containers or reefer will keep the product at low temperature in shipping process. Cargo should be placed in an area within the reefer where the temperature is close to the optimal temperature for each product. This research will develop a Refrigerated-Container Loading Problem (R-CLP) model for refrigerated containers that load ventilated cargo for shipping fruits and vegetables. The model will be developed using constructive heuristic method using wall-building approach. Researchers will conduct simulations using Computational Fluid Dynamics (CFD) to obtain temperature distribution data in the reefer and the cargo. The purpose of this research is to produce a decision support tools to optimize the yield of agricultural and reduce food loss due to the distribution process. The numerical experiment results shows about the ability of the model to minimize cost and quality loss. The numerical experiment results also show that using ventilated cargo have a better results than closed cargo for loading fruit products. The fruit produces heat as a result of respiration which must be removed from the cargo. Ventilation holes facilitate cool air from reefer entering the cargo and hot air from fruit exiting the cargo. To get a similar temperature distribution between closed cargo and ventilated cargo, the temperature in the closed cargo must be less that 2°C compared to ventilated cargo.
