Development of Internet of Things (IoT) based learning media in efforts to improve student skills at the industrial revolution era 4.0

Practicum is an essential component in the learning process at universities, especially in the fields of science and technology. Realizing quality practicum requires a balanced amount of equipment that supports the process, but practicum participants often exceed practicum equipment. The solution is to create a remote laboratory that can be accessed from anywhere while connected to the internet. The remote laboratory consists of three essential parts, namely a server that includes a computer or laptop connected to the data processor sent by the user and then connected to the actuator, a server is also connected to the camera that the user can observe the practical work. The second part is an internet connection, and the third part is the user. All that is controlled by ThinVNC software, Ngrok, and GUI that has been provided. On the server computer, GUI, ThinVNC, and Ngrok are installed as controllers for the practical work, while the user can open the website to access the lab computer. Based on theory and experience, this technique is very suitable if used in PLC and pneumatic practicum. The use of remote labs makes students more skilled in facing the era of the industrial revolution 4.0.
