Abstract
Salah satu pabrik Petrokimia di Gresik, dalam memproduksi bahan baku STPP memerlukan tiga peralatan utama yaitu Spray Dryer, Calciner, dan Boiler. Untuk mengoperasikan ketiga peralatan tersebut, menggunakan bahan bakar gas sebagai bahan bakar Burner di setiap ketiga peralatan tersebut. Burner tersebut digunakan untuk kebutuhan proses yang berbeda-beda yaitu untuk sebagai pemanas tambahan untuk boiler, kemudian untuk spray dryer digunakan sebagai tambahan udara panas begitupun di calciner. Dari hal tersebut dilakukan pengendalian temperatur berdasarkan referensi dari tekanan yang ada di pressure regulator dan bukaan dari solenoid valve yang dikonversikan melalui pemodelan matematis sehingga dapat merepresentasikan temperatur dari burner masing-masing peralatan. Dengan menggunakan PID controller pada Simulink matlab dengan metode trial and error berdasarkan perubahan nilai kurva reaksi yang menghasilkan respon untuk kedua burner boiler dengan (td = 25,07s , tr = 38,61s, tp = 79,55s, mp = 3,913%, tr = 219 s) untuk mencapai 1200 C, lalu untuk satu burner spray dryer (td = 20,6s, tr = 36,40s , tp = 77,517s, mp = 3,11%, ts = 215,3 s) untuk mencapai 1200 C, kemudian untuk satu burner calciner (td = 17,21s , tr = 24,84s, tp = 58,626 detik, mp = 14,82%, ts = 309s) untuk mencapai 1200 C. Selanjutnya switch sebagai pengendali on/off secara otomatis saat trip sehingga dapat dilakukan langsung pada control room tanpa harus turun ke lapangan dalam hal ini direpresentasikan simulasi akan berhenti.

One of the Petrochemical factories in Gresik, in producing STPP raw materials requires three main tools namely Spray Dryer, Calciner, and Boiler. To operate the three equipment, use the fuel gas as Burner fuel in each of the three equipment. The burner is used for different process requirements that is for as an additional heater for the boiler, then for spray dryer is used in addition to hot air as well as in the calciner. The temperature control is based on the reference of the pressure in the pressure regulator and the opening of the solenoid valve converted by mathematical modeling so that it can represent the temperature of the burner of each equipment. By using PID controller in Simulink matlab with trial and error method based on the change of reaction curve value which yield response for both boiler burner with (td = 25,07s, tr = 38,61s, tp = 79,55s, mp = 3,913%, tr = 219 s) to reach 1200 oC, then for one burner spray dryer (td = 20,6s, tr = 36,40s, tp = 77,517s, mp = 3,11%, ts = 215,3s) to reach 1200 oC, Then for one calciner burner (td = 17.21s, tr = 24.84s, tp = 58.626sec, mp = 14.82%, ts = 309s) to reach 1200 oC. Next switch as the controller on / off automatically when the trip so it can be done directly on the control room without having to go down to the field in this case is represented the simulation will stop.
