Design and Construction of an IoT-Based Smart Laboratory at the Information Technology Study Program Laboratory of the PSDKU Pontianak State Polytechnic in Sukamara Regency

Abstract

The Software and Networking Laboratory of the Information Technology Study Program at the Off-Campus Program of Politeknik Negeri Pontianak in Sukamara Regency serves as a space for practical work and research for students. However, the safety and security systems in this laboratory are still very minimal, relying only on CCTV cameras. This poses risks to the safety and security of students and laboratory equipment, especially when the laboratory is not directly supervised. This study aims to design an Internet of Things (IoT)-based monitoring system that enables real-time and remote monitoring of the laboratory space by technicians, laboratory heads, and study program coordinators. The system is designed to be accessible via mobile devices and computers. The methodology used consists of eight stages: defining the project's goals and requirements, designing the system architecture, developing the User Experience (UX) interface, and assembling and integrating hardware and software components. The ESP32 microprocessor is used as the main controller, connected to the IoT platform Thingsboard to monitor temperature, humidity, and access conditions in the laboratory. The system is also equipped with automatic notifications in case of emergency situations. The IoT devices have been installed in the software laboratory, networking laboratory, and library, and they function as designed. The result of this research is a prototype of an IoT-based monitoring system ready to be tested to enhance the safety and security of the laboratory environment
