Abstract
Salah satu cara menghilangkan kadar H2S dari gas alam adalah dengan pembakaran. Gas sisa dari pembakaran ini masih memberi dampak negatif terhadap lingkungan, salah satunya yaitu SO2. Larutan asam H2SO4 yang masuk ke CSTR bersifat asam sehingga pH larutan tersebut harus dikendalikan menjadi basa agar aman dibuang ke lingkungan. Pengendalian pH menggunakan dua pemodelan yaitu statik dan dinamik. Agar sistem pengendalian mencapai set point pH sebesar 7,5 digunakan metode Fuzzy-PID. Berdasarkan hasil dari simulasi menggunakan MATLAB-SIMULINK, pengendali PID biasa pada uji set point mendapatkan settling time 48,787 detik dan Integral Absolute Error 25,77. Untuk pengendali Fuzzy-PID didapatkan settling time 46,735 detik dan Integral Absolute Error 24,77. Sehingga disimpulkan pengendali Fuzzy-PID menghasilkan respon yang lebih baik.

One from many way to remove H2S from natural gas is by combustion. The residual gas from this combustion still gives negative impact to the environment, one of them is SO2. H2SO4 acid solution into the CSTR is acidic so that the pH of the solution must be controlled to be a base for safe discharge into the environment. PH control uses two static and dynamic modeling. In order for the control system to reach the set point pH of 7.5 used Fuzzy-PID method. Based on the result of simulation using MATLAB-SIMULINK, the usual PID controller on set point test get settling time 48,787 seconds and Integral Absolute Error 25.77. For the Fuzzy-PID controller the settling time is 46,735 seconds and the Integral Absolute Error 24.77. So it is concluded that Fuzzy-PID controller produces better response.
