Abstract
Produksi pupuk pada PT Petrokimia ini memerlukan
steam yang dihasilkan oleh steam drum sebagai komponen
pendukung proses produksi. Bahan baku utama produksi
steam pada steam drum adalah air. Air umpan steam drum
harus tidak mengandung O2 sehingga dihilangkan terlebih
dahulu pada sistem Deaerator . Pada penelitian tugas akhir
ini, akan dirancang kontrol level pada deaerator
menggunakan fuzzy logic control. Berdasarkan hasil
pengujian sistem didapatkan bahwa menggunakan kontroler
fuzzy menunjukan respon menuju set point dan menjaga tetap
stabil Pada pengujian tracking set point naik dan turun, sistem
dapat bergerak menuju set point. Pengendali PI pada plant
deaerator 101 U masih konvensional sehingga dapat diatasi
dengan kontrol modern logika fuzzy yang memiliki parameter
kestabilan lebih baik yaitu maximum overshoot (MP) sebesar
0.83 % , settling time 71 detik ,error steady state (ess) sebesar
1.2% sedangkan PI kontrol maximum overshoot (MP) sebesar
16 % , settling time 384 detik error steady state (ess) sebesar
0.04%
==============================================================================================
Fertilizer production at PT Petrokima requires steam by
the steam drum as a supporting component of the production
process. The main raw material production of steam in the steam
drum is water. Feedwater steam drum should not be contain O2
so it will removed on Deaerator system. In this research, will be
designed in the deaerator level control using fuzzy logic control.
Based on test results showed that the test system using fuzzy
controller shows the system's response towards the set point and
keep steady , In the tracking set point test, the system can move
towards the set point. In the comparison of fuzzy and PI response
system, fuzzy controller respon’s is better than the PI controller
with performance parameter’s , settling time 71 seconds ,error
steady state (ess)of 1.2% and maximum overshoot (MP) of 0.83 %
Therefore PI control with performance parameter’s maximum
overshoot (MP) of 16 % , settling time 384 seconds error steady
state (ess) of 0.04%
