"This paper investigates the stack effect on the power consumption of refrigerated containers. The investigation is based on measurement experimentation that was conducted in Hakata Island City Container Terminal, Fukuoka, Japan. Experimentation was carried out over summer 2015, using three stacks of high cube refrigerated containers. Several sensors and devices were employed to ascertain parameters, including pyranometers, thermocouples, and power analyzers. Five units of pyranometers were set on a horizontal and vertical plane, facing all cardinal directions. Thermocouples were installed inside and outside of walls at a total of twenty points. Power meters employed to measure energy consumption were set on the power plug station nearby the measurement object. Measurement results showed that the stacking position of refrigerated containers affects the distribution of surface temperatures and power consumption. The average surface temperatures obtained on the top tier, middle tier, and bottom tier were 45°C, 41°C and 38°C at noon, respectively. Consequently, the average power consumption from the top tier, middle tier, and bottom tier were shown as 7.7 kW, 7.4 kW and 7.5 kW, respectively. From these results it can be concluded that the stacking effect of containers provides thermal benefit to the power consumption of refrigerated containers that are located on the middle tier and bottom tier."

"Penanganan kontainer berpendingin atau refrigerated container memiliki tantangan yang lebih besar karena membutuhkan efisiensi yang tinggi. Penanganan melalui pemantauan manual di lapangan penumpukan menimbulkan risiko terhadap kerusakan muatan akibat ketidakmampuan dalam memberikan respons dengan cepat. Tujuan dari penelitian ini adalah merancang perbaikan proses penanganan refrigerated container melalui penggunaan teknologi internet of things (IoT) dengan pendekatan business process re-engineering (BPR) untuk mendapatkan informasi secara real-time dalam menjaga muatan dari kerusakan dan mempercepat waktu proses penanganan di terminal kontainer. Penelitian ini memiliki tiga skenario perbaikan proses yang terdiri dari kombinasi perbaikan BPR best practice melalui integrasi teknologi, yaitu dengan pengimplementasian automatic container damage detection system (ACDD) dan IoT based reefer real-time monitoring system (RRMS). Hasil simulasi terhadap ketiga skenario tersebut menghasilkan waktu proses penanganan yang berbeda untuk setiap skenario. Model sistem informasi juga dirancang untuk mendukung hasil proses perbaikan bisnis dengan mengadopsi model To-Be skenario ketiga yang merupakan skenario terlengkap dari penelitian dengan penurunan waktu siklus keseluruhan proses sebesar 61,7%.

Handling refrigerated containers poses more significant challenges because they require high efficiency. Handling through manual monitoring in the stacking yard poses the risk of cargo damage due to the inability to respond quickly. The purpose of this research is to design improvements of the refrigerated container handling process through the implementation of internet of things (IoT) technology with a business process re-engineering (BPR) approach to obtain real-time information in keeping cargo from damage and increase the processing time at container terminals. This study has three process improvement scenarios consisting of a combination of best practice BPR improvement through technology integration by implementing the automatic container damage detection system (ACDD) and IoT based reefer real-time monitoring system (RRMS). The simulation results for the three scenarios resulted in different handling processing times for each scenario. The information system model is also designed to support the business improvement process's results by adopting the third scenario To-Be model, which is the most comprehensive scenario from the study, with a reduction in the cycle time of the entire process by 61.7%."
