An Inventory Tool for Receiving Practicum Report Based on IoT by Using ESP32-CAM and UV Sterilizer: A Case Study at Muhammadiyah University of Sidoarjo

Abstract

Currently, there are several problems related to practicum report collection in
the electrical engineering laboratory at the Muhammadiyah University of Sidoarjo. The first
problem is the presence of crowds during practicum report collection that have their
dangers, specifically during the Covid-19 pandemic. Another problem is the absence of
laboratory assistants in the electrical engineering laboratory when there are students who
will collect reports. A tool that can receive practicum reports was made from these problems,
and it can be monitored remotely by a laboratory assistant. By putting an RFID card to the
RFID sensor on the box so that the solenoid can open the box door and the student can put
the report into the box. At the same time, ESP32-CAM takes pictures of students collecting
the report. Then, notification in the form of photos and student information will be sent to
the laboratory assistant through the Telegram application. After the report is placed into the
box, the UV Sterilizer will turn on to disinfect the report. The expectation of making this tool
is to facilitate the collecting report process of practicum results and reduce the crowd in the
laboratory.
