Abstract

Sistem pemantauan dan pengendalian level permukaan air memerlukan presisi dan responsivitas maksimal terhadap perubahan level air yang tidak dapat dicapai melalui proses manual. Oleh karena itu, penelitian ini dilakukan dengan merancang sistem otomasi pompa air pada simulator level permukaan air berbasis Arduino ESP32-S3 Nano dan PLC Mitsubhisi FX3U. Simulator ini terdiri dari dua buah tangki, dimana tangka 1 berfungsi sebagai tandon (inlet) dan tangki 2 berfungsi sebagai representasi dari wadah dari air seperti sungai yang permukaannya dikendalikan. Sistem ini dilengkapi dengan satu pompa inlet yang mensimulasikan pasokan air dari hulu atau curah hujan, serta tiga buah pompa outlet untuk membuang air dari tangki 2. Sensor ultrasonic HC-SR04 digunakan untuk membaca ketinggian permukaan air pada tangki 2 secara real-time. Data keluaran dari sensor akan diproses oleh Arduino ESP32-S3 Nano dan dikirim ke PLC untuk menentukan logika operasi dari pompa secara otomatis. Sistem ini juga dilengkapi dengan layar LCD lokal yang menampilkan informasi ketinggian air, status pompa, dan kondisi sistem sistem secara real-time. Pengujian dilakukan dalam tiga skenario. Hasil pengujian menunjukkan bahwa dalam skenario 1, sistem menunjukkan adanya overshoot hingga 34 cm dan memasuki kondisi steady pada detik ke-160. Pada skenario 2, sistem mengalami overshoot yang lebih besar yaitu 54 cm dan settling time sekitar 220 detik. Sedangkan skenario 3 terjadi overshoot hingga 67 cm dan membutuhkan waktu 330 detik untuk mencapai kondisi steady.

The water level monitoring and control system requires high precision and responsiveness to changes in water level, which cannot be achieved through manual processes. Therefore, this research was conducted by designing an automated pump control system on a water level simulator using the Arduino ESP32-S3 Nano and Mitsubishi FX3U PLC. The simulator consists of two tanks: Tank 1 functions as a reservoir (inlet), while Tank 2 represents a water body such as a river, whose surface level is controlled. The system is equipped with one inlet pump to simulate water inflow from upstream or rainfall, and three outlet pumps to discharge water from Tank 2. An HC-SR04 ultrasonic sensor is used to measure the water level in Tank 2 in real time. The sensor output is processed by the Arduino ESP32-S3 Nano and sent to the PLC, which determines the automatic operation logic of the outlet pumps. The system also includes a local LCD display that shows real-time information on water level, pump status, and overall system conditions. Testing was carried out under three different scenarios. The results showed that in Scenario 1, the system experienced an overshoot of up to 34 cm and reached a steady-state at 160 seconds. In Scenario 2, the system had a larger overshoot of 54 cm with a settling time of approximately 220 seconds. In Scenario 3, the overshoot reached 67 cm and required 330 seconds to stabilize.
