Penelitian ini membahas perancangan dan implementasi sistem pengendalian level cairan pada vessel menggunakan mikrokontroler ESP32 yang terintegrasi dengan teknologi Internet of Things (IoT). Sensor ultrasonik digunakan untuk mengukur ketinggian cairan, sementara aktuator berupa servo valve mengatur aliran masuk berdasarkan data yang diproses oleh ESP32. Sistem ini dikendalikan dan dipantau secara real-time melalui aplikasi Blynk yang berfungsi sebagai antarmuka pengguna pada perangkat mobile. Selain pemantauan jarak jauh, penggunaan Blynk dapat memungkinkan pengaturan setpoint dan gain dari kontroler secara real time. Sistem dirancang untuk meningkatkan efisiensi dan akurasi dalam pengendalian proses cairan. Selain itu, integrasi IoT memungkinkan pemantauan jarak jauh dan pengambilan keputusan yang lebih responsif. Tiga metode tuning kontroler PID dibandingkan dalam pengujian, yaitu Cohen-Coon, Ziegler-Nichols, dan Internal Model Control (IMC). Berdasarkan hasil pengujian, metode Cohen-Coon dengan kontroler PI memberikan kinerja paling optimal dengan rise time sebesar 17 detik, settling time sebesar 62 detik, dan overshoot sebesar 5%. Konfigurasi ini direkomendasikan karena mampu memberikan respons cepat, minim osilasi, dan kestabilan tinggi. Skala laboratorium sebagai solusi otomatisasi yang efisien dan hemat biaya.
