Abstract

Since the Covid-19 pandemic occurred, teaching and learning activities must be held remotely. Learning is done online. Students and lecturers carry out WFH (work from home). In principle, online learning is not expected to reduce the knowledge transfer process. However, in terms of learning that requires tools or practicum activities, it is still necessary to get a breakthrough to replace these activities with WFH. In this regard, research is proposed to develop and build a prototype of a basic refrigeration system training unit that students can access online at their respective places using a computer, tablet, or smartphone. Students can do practical work on the refrigeration system through this device, starting from how the system works, instrumentation, control, and online operation on equipment placed in the laboratory. With the development of a device system that can be accessed remotely, it was found that direct learning activities can be replaced online, although not completely. The steps taken started from designing the refrigeration system, instrumentation, control and supporting software for online or remote access learning systems, web servers, building a refrigeration system training unit, and system integration. Remote access is built with a web server in LOGO PLC. The result can be presented in the form of Ms. Excel files. The condition of the refrigeration system can be set remotely. The system can be monitored from the user interface which displays system data and state. The average value of COP and the refrigeration system’s efficiency is 3.9 and 76% respectively.
