Abstract

This study develops an IoT-based Fresh Fruit Bunch (FFB) filling prototype for vertical sterilizers using the HC-SR04 ultrasonic sensor to enhance the accuracy and efficiency of the filling process in palm oil mills. The system incorporates a non-contact distance sensor to ensure precise measurement and integrates IoT technology and a Telegram bot for real-time monitoring and automation. Testing results indicated that the HC-SR04 sensor achieved high accuracy, maintaining a low tool failure rate of 0.036%, making it highly reliable for industrial applications. Visual and audio indicators, including LEDs and buzzers, were used to enhance user awareness and safety during the filling process. By automating and optimizing FFB loading, the system minimizes operational inefficiencies commonly associated with manual filling methods and improves safety by reducing human intervention. These findings suggest that the developed prototype can provide significant operational benefits to the palm oil industry and other sectors requiring similar improvements in productivity and sustainability. Future research will focus on refining the prototype and evaluating its scalability for broader industrial use.

Abstract

This study presents the design and implementation of an IoT-based automated conveyor system using the ESP32 microcontroller and Telegram bot for remote control. The system integrates the L298N motor driver to precisely control the speed and direction of a 12V DC motor. Telegram serves as the communication platform, enabling real-time notifications, remote monitoring, and operational control, thereby enhancing user convenience and operational flexibility. The experimental results demonstrate the system's stability across various operating conditions. Testing revealed consistent performance in controlling motor speed and direction without overheating or disruptions, even during extended operations. The system effectively integrates IoT and automation technologies to provide a scalable, cost-effective solution for modern industrial conveyor systems. This research contributes to the advancement of Industry 4.0 by addressing the growing demand for efficient, remote-controlled automation. The proposed system offers significant potential for application in industrial settings, emphasizing reliability, ease of use, and adaptability. Future enhancements could focus on incorporating additional sensors and advanced analytics to improve system intelligence and extend functionality.
