Abstract
Pada Test Separator milik Total E&P Indonesie digunakan untuk memisahkan hydrocarbon berdasarkan masa jenis kedalam tiga fasa berupa minyak, air dan gas. Level minyak harus dijaga pada ketinggian 50%, karena jika melebihi atau kurang dari set point akan mengganggu
proses pemisahan serta dapat mengaktifkan Level Alarm yang mengakibatkan shutdown system. Level diatur menggunakan kontroler Proportional Integral Derivative (PID). Namun karena penentuan parameter kontroler menggunakan metode trial and error. Respon data
dari real plant yang didapat memiliki error steady state, overshoot dan time constant yang besar. Beberapa metode kontroler PID dapat digunakan yaitu Ziegler-Nichols, Cohen-Coon dan Analitik, dengan terlebih dahulu mendapatkan model matematis menggunakan identifikasi dinamis bentuk Auto Regressive Moving Average (ARMA)
melalui metode Pendekatan Penyelesaian Persamaan Linier Simultan Parameter Total (P3LS-PT) dan ditentukan nilai Integral Absolute Error (IAE) terkecil dari beberapa model yang didapat. Hasil model yang didapat digunakan juga untuk training simulator Human Machine Interface (HMI). Hasil simulasi pengujian kontroler, didapatkan bahwa dari metode Analitik t*=t dengan parameter Kp=19.23076 dan ti=302.18 s memiliki respons terbaik dan memenuhi spesifikasi desain dengan 0% error steady state, 0% overshoot dan time constant 300.73 s, respons dengan gangguan memiliki error steady state 5% dan memiliki
time constant 304.73 s, serta sinyal kontrol memiliki nilai fluktuatif terkecil sebesar 10.0323%. Hasil parameter kontroler dan simulator HMI akan menjadi rekomendasi serta media training bagi operator di
Total E&P Indonesie.

In Test Separator belongs to Total E & P Indonesie used to
separate hydrocarbon-based specify gravity into three phases types such
as oil, water and gas. Oil level should be maintained at a height of 50%,
because if it exceeds or is less than the set point will disrupt the process
of separation and can activate the alarm level that will make shutdown
system. The level is set using the controller Proportional Integral
Derivative (PID). However, because the determination of the controller
parameters using the trial and error method. Response data from real
plant that has gained steady state error, the overshoot and the big time
constant. Several methods of PID controllers can be used is the Ziegler-
Nichols, Cohen-Coon and Analytical, by first obtaining a mathematical
model using dynamic identification form Auto Regressive Moving
Average (ARMA) through the method of Simultaneous Linear
Equations Total Parameter Approach (P3LS-PT) and determined value
Integral Absolute Error (IAE), The smallest of the models obtained.
Results obtained model was also used for Human Machine Interface
(HMI) training simulators. The simulation results of testing the
controller, it was found that of the Analytical method t*=t parameters
Kp = 19.23076 and ti = 302.18 s has the best response and meet design
specifications with 0% error steady state, 0% overshoot and the time
constant 300.73 s, the response with disturbance has a 5% error steady
state and has a time constant 304.73 s, as well as the control signal
having the smallest fluctuation value of 10.0323%. Results parameter
controller and HMI simulator will be a recommendation as well as media training for operators at Total E & P Indonesie.
