Abstract
Deaerator adalah alat yang berfungsi untuk menghilangkan
kandungan oksigen pada make up water sebelum masuk ke boiler
dan heat exchanger. Deaerator bekerja dengan memanfaatkan
kandungan oksigen yang terdapat pada steam untuk pelepasan
kandungan oksigen pada make up water. Pengendalian level pada
deaerator perlu dilakukan untuk menjaga kestabilan pasokan air
ke boiler dan heat exchanger. Perancangan sistem pengendalian
dengan metode Internal Model Control bertujuan agar respon
pengendali memiliki performansi yang lebih baik daripada
pengendalian PID. Dari hasil simulasi didapatkan bahwa
pengendali IMC memiliki respon yang lebih baik pada saat uji
disturbance dan mampu mencapai set point pada saat uji tracking
set point. Parameter tuning IMC menunjukan respon terbaik pada
saat λ = 1. Parameter respon pengendali IMC yang didapatkan
yaitu settling time = 14,56 s dan IAE = 20,92.

Deaerator is a tool that serves to eliminate the oxygen content of
the make-up water before it enters the boiler and heat exchanger.
Deaerator works by utilizing the oxygen content contained in the
steam to release oxygen content of the make-up water. Control of
the deaerator level necessary to maintain a stable water supply to
the boiler and heat exchanger. The design of control systems with
the Internal Model Control method aims to control the response
has better performance than the PID control. From the
simulation results showed that the IMC controller has better
response at the time of the disturbance test and is able to achieve
set point when the set point tracking test. IMC tuning parameters
showed the best response when λ = 1. IMC controller response
parameters were obtained, settling time = 14,56 s and IAE =
20,92.
