ABSTRAK

Reverse osmosis adalah suatu proses pembalikan dari proses osmosis. Osmosis adalah proses perpindahan larutan dari larutan dengan konsentrasi zat terlarut rendah menuju larutan dengan konsentrasi zat terlarut lebih tinggi sampai terjadi kesetimbangan konsentrasi. Dalam penelitian ini telah dilakukan pengendalian proses RO dalam Simulink Matlab dengan menggunakan metode Internal Model Control IMC secara invers yang menanggulangi rawan pecahnya membrane RO kembali. Pada RO pertama dan RO kedua menggunakan menggunakan IMC controller untuk pengendali tekanan. Pengendalian dengan model IMC ini menggunakan sistem pengendalian unity dimana masukan dari sistem proses akan distabilkan pada keluaran proses sehingga sesuai dengan setpoint dari masukan proses. Faktor utama dalam penstabilan pengendalian ini adalah pada nlai gain flter hingga mencapai respon signal yang sesuai dengan setpoint. Dari hasil penelitian terlihat bahwa saat pengendali IMC unity ini diberikan suatu disturbance berupa signal sinus maka yang terjadi pada respon sistem membentuk signal osilasi yang stabil tetapi tanpa terjadi redaman sempurna. Hasil untuk metode controller IMC unity ini yaitu pada RO1 maksimal overshoot sebesar 16.5 settling time saat 19 detik dan pada RO2 maksimal overshoot sebesar 0.84 settling time saat 17 detik.


ABSTRACT

Reverse osmosis is a process of reversal of the process of osmosis. Osmosis is the process of moving the solution from the solution with low solute concentration to a solution with higher solute concentration until there is equilibrium concentration. In the present study was conducted RO process control in Matlab Simulink using the Internal Model Control IMC is the inverse of the RO membrane rupture-prone tackling back. In the first RO and RO using the IMC controller both use to control the pressure. IMC control with this model of unity of control system where the input of the system will be stabilized in accordance with the output of the process so that the setpoint of the feedback process. A major factor in stabilizing this control is on nlai flter gain reaching a response signal corresponding to the setpoint. From the research shows that when unity IMC controller is given a disturbance of the sinus signal occurring at the response of the system to form a stable oscillation signal without any attenuation but perfect. The results for this unity IMC controller method that is in RO1 by 16.5 maximum overshoot settling time at 19 seconds and in RO2 maximum of 0.84 overshoot settling time at 17 seconds.
