Abstract
Penelitian ini bertujuan untuk merancang, mengembangkan, dan menguji prototipe sistem monitoring dan kontrol ketinggian air irigasi menggunakan protokol Modbus RTU dan teknologi Internet of Things (IoT) yang terintegrasi dengan Human Machine Interface (HMI). Sistem ini memanfaatkan sensor ultrasonik untuk memantau ketinggian air sungai dan saluran irigasi secara real-time, dengan data diolah oleh mikrokontroler ESP32 menggunakan logika fuzzy untuk mengendalikan pintu air secara otomatis melalui motor DC. Data ketinggian air dan status pintu air dikirim ke HMI Haiwell melalui komunikasi Modbus RTU untuk pemantauan jarak jauh. Pengujian dilakukan pada maket laboratorium, menunjukkan bahwa sistem mampu mendeteksi ketinggian air dengan akurasi rata-rata 97,92% (sensor 1) dan 98,90% (sensor 2), serta mengatur pintu air secara otomatis sesuai kondisi air (rendah, normal, tinggi). Sistem ini berhasil mengelola distribusi air dan mencegah overload dengan menutup pintu air saat ketinggian melebihi batas, meskipun akurasi sensor sedikit dipengaruhi oleh percikan air. Penelitian ini memberikan solusi efisien untuk otomatisasi irigasi, mengurangi ketergantungan pada pengoperasian manual, dan mendukung pengelolaan air yang lebih akurat dan responsif.

The system employs ultrasonic sensors to monitor river and irrigation channel water levels in real-time, with data processed by an ESP32 microcontroller using fuzzy logic to automatically control water gates via DC motors. Water level data and gate status are transmitted to the Haiwell HMI through Modbus RTU communication for remote monitoring. Testing conducted on a laboratory-scale mockup demonstrated that the system can detect water levels with an average accuracy of 97.92% (sensor 1) and 98.90% (sensor 2), and automatically adjust water gates based on water conditions (low, normal, high). The system effectively manages water distribution and prevents overflow by closing gates when water levels exceed the threshold, although sensor accuracy is slightly affected by water splashes. This research provides an efficient solution for irrigation automation, reducing reliance on manual operations and supporting more accurate and responsive water management.
