Abstract

This study aims to design and develop a mixing liquid machine trainer kit based on a Programmable Logic Controller (PLC) and Human Machine Interface (HMI) as a learning medium for the Industrial Control Systems course at SMK Negeri 1 Padang. The background of this research is the limited availability of practical learning media in the laboratory, which is still simple and not yet integrated with industrial automation systems required by the workforce, resulting in a lack of students’ hands-on experience in operating industrial control systems. This research employed a Research and Development (R&D) method using a development model consisting of needs analysis, design, development, validation, and practicality testing stages. The resulting product is a trainer kit that simulates a two-liquid mixing process using an automatic control system based on the Omron CP1E E40SDR-A PLC and process visualization through an EasyBuilder Pro-based HMI. The results show that the developed product has a very high level of validity based on expert evaluations in both material and media aspects, and it also demonstrates a high level of practicality based on student trials. This indicates that the developed trainer kit is feasible and effective as a learning medium to improve students’ conceptual understanding and practical skills in industrial control systems. Therefore, this trainer kit is expected to bridge the competency gap between vocational school graduates and industrial demands, particularly in PLC- and HMI-based automation systems.

Abstract

This study aims to design and develop a flood early warning system prototype based on the ESP32 microcontroller using LoRa communication technology and integration with the ThingSpeak platform as an Internet of Things (IoT) monitoring system. The system was developed to address the limitations of previous flood monitoring systems, which were constrained by limited communication range and the lack of real-time information delivery to the public. The development method used is the Waterfall model, consisting of requirement analysis, system design, implementation, and testing stages. The system consists of a transmitter unit equipped with an ultrasonic sensor, a water level sensor, and a water flow sensor used to detect water height and flow conditions. The sensor data is processed by the ESP32 microcontroller and transmitted via a LoRa module to the receiver unit. On the receiver side, the ESP32 is connected to the internet to send data to the ThingSpeak platform, enabling real-time monitoring in the form of graphs and flood status indicators. The results show that the system is capable of accurately detecting changes in water level and flow while providing a wider communication range compared to previous nRF-based systems. The integration of LoRa offers advantages in power efficiency and transmission distance, while the ESP32 ensures stable IoT connectivity. Therefore, this prototype can serve as an effective, fast, and accessible alternative flood early warning system to support disaster mitigation in flood-prone areas.
