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

Automation technology has significantly improved the efficiency of various sectors, including car washing services, which traditionally require intensive time and labor.This research aims to design and develop a prototype of an automatic car washing system using Outseal PLC and Modbus HMI to enhance the effectiveness and quality of car washing processes.The prototype integrates infrared proximity sensors, DC gearbox motors, DC pumps, DC fans, and a conveyor system controlled by a ladder diagram programmed through Outseal Studio. Wireless monitoring and control are enabled using the DT-06 WiFi module with Modbus TCP/IP protocol. Performance testing was conducted to evaluate system responsiveness, sensor accuracy, and the stability of wireless communication between the PLC and HMI.The system successfully automated all stages of the car washing process, including soap spraying, brushing, rinsing with clean water, and drying, achieving response times ranging from 0.14 to 0.3 seconds. Wireless communication remained stable up to a distance of 16 meters, and the infrared proximity sensors demonstrated high detection accuracy with an error margin of only 2–3.2%.The developed prototype effectively automates the car washing process with accurate detection and responsive control, operating reliably under testing conditions. This system is suitable for small-scale car washing operations and educational laboratory applications, with potential scalability for broader industrial implementation with additional development in advanced brush mechanisms and cloud-based monitoring integration.

Abstract

Motor induksi tiga fasa banyak digunakan sebagai penggerak konveyor batubara pada coal feeder PLTU karena konstruksinya yang sederhana dan andal. Namun, karakteristik nonlinier motor induksi menyebabkan kecepatan motor sulit dipertahankan konstan saat terjadi perubahan beban, sehingga mengganggu kestabilan aliran batubara dan menurunkan efisiensi pembakaran. Oleh karena itu, diperlukan sistem kendali yang mampu menjaga kestabilan kecepatan motor secara adaptif. Penelitian ini bertujuan menganalisis kinerja pengendalian kecepatan motor induksi menggunakan metode Fuzzy-PID dan membandingkannya dengan PID konvensional. Metode penelitian dilakukan melalui pemodelan matematis motor induksi, perancangan pengendali Fuzzy-PID berbasis aturan Mamdani, serta simulasi menggunakan Simulink MATLAB. Pengujian dilakukan pada kondisi setpoint konstan, perubahan setpoint, dan variasi beban. Hasil simulasi menunjukkan bahwa pengendali Fuzzy-PID mampu memberikan respon yang lebih baik dengan rise time dalam waktu 0.5 detik, overshoot sebesar 0,8% dan undershoot dibawah 1%, serta kestabilan arus yang lebih baik dibandingkan PID konvensional. Dengan demikian, metode Fuzzy-PID terbukti lebih efektif dalam menjaga kestabilan kecepatan motor induksi dan meningkatkan keandalan sistem konveyor batubara di PLTU.
