Abstract

Salah satu jenis reaktor yang banyak digunakan dalam proses waste water treatment adalah Continuous Stirred-Tank Reactor (CSTR). Aliran massa masuk dan keluar berlangsung secara terus-menerus serta terjadi proses di dalamnya (pada penelitian ini) yaitu reaksi penetralan asam kuat HCl dan basa kuat KOH. Debit aliran larutan KOH kemudian dikendalikan menggunakan pengendalian PID dengan berbagai macam metode tuning. Dengan pendekatan FOPDT (First Order Plus Dead Time) pada sistem close loop, nilai-nilai karakteristik dinamik sistem didapatkan lalu diterapkan pada metode tuning untuk menentukan metode yang terbaik sesuai karakteristik pengendalian sistem. Percobaan dilakukan pada software MATLAB. Sistem pengendalian diberikan set point pH sebesar 7, disturbance pada debit aliran asam, dan diberikan perbedaan pada metode tuning pengendalian PID. Hasil yang baik diperoleh dari metode tuning Cohen-Coon yaitu dengan maximum overshoot dan error steady state sebesar 0%, serta settling time sebesar 72,9 detik. =============================================================================================== Kind of reactor that is widely used in the waste water treatment process is a Continuous Stirred Tank Reactor (CSTR). The mass flow rate of input and output takes place continuously and there is a process in it (in this study) that is the reaction of neutralizing the strong acid HCl and the strong base of KOH. The KOH solution is then controlled using PID control with a variety of tuning methods. With the FOPDT (First Order Plus Dead Time) approach the control parameters are obtained and then the tuning method is applied to determine which method best fits the system's static characteristics. The experiment was carried out in MATLAB software. Given a pH set point of 7 and given variations on the PID control tuning method. Good results are obtained from the Cohen-Coon tuning method which is with maximum overshoot and steady-state error of 0%, and a settling time of 72,9 seconds. This is a good result according to the characteristics of the control system in accordance with the plant in previous studies.
