Pengendalian level air pada boiler merupakan aspek penting untuk menjaga efisiensi dan keselamatan operasional, karena ketidakstabilan level air dapat menyebabkan gangguan proses dan potensi kerusakan peralatan. Penelitian ini bertujuan untuk membandingkan kinerja metode tuning PI controller menggunakan Ziegler-Nichols dan Cohen-Coon pada sistem pengendalian level air Tangki 11 Boiler Drum Simulator BDT921 di PPSDM Migas Cepu. Berdasarkan tinjauan pustaka, kedua metode memiliki karakteristik perhitungan parameter Kp dan Ti yang berbeda, sehingga memengaruhi respons transien sistem. Penelitian dilakukan secara eksperimental dengan pengujian step input pada manipulated variable (MV) untuk memperoleh data karakteristik respons sistem, meliputi dead time (DT) dan time constant (TC). Parameter DT dan TC digunakan untuk menentukan nilai Kp dan Ti PI controller sesuai formulasi masing-masing metode tuning. Simulasi dilakukan menggunakan MATLAB untuk menganalisis rise time, settling time, overshoot, dan peak time. Hasil penelitian menunjukkan bahwa metode Ziegler-Nichols menghasilkan rise time 0,8376 s dan settling time 1,2828 s, lebih cepat dibanding Cohen-Coon yang memiliki rise time 1,0314 s dan settling time 1,5990 s. Kedua metode menghasilkan respons yang stabil tanpa overshoot maupun undershoot, dengan peak time masing-masing sebesar 13,0136 s dan 13,9836 s. Berdasarkan hasil tersebut, metode Ziegler-Nichols memberikan respons sistem yang lebih cepat tanpa mengurangi kestabilan, sehingga direkomendasikan untuk aplikasi pengendalian level air boiler yang membutuhkan respons cepat dan stabil.
