Abstract

Steam Boiler berperan penting dalam menghasilkan steam sesuai dengan kebutuhan berbagai proses yang ada di dalam plant tersebut. Pada berbagai proses dalam suatu plant, steam yang digunakan memerlukan kondisi tekanan dan suhu yang sesuai dengan kebutuhan. Disisi lain, kuantitas dari supply steam ke masing-masing proses tersebut tidak selalu sama bergantung dari kebutuhan proses akan steam tersebut. Bervariasinya kuantitas kebutuhan pada plant tentunya menjadi beban bagi boiler. Pengendalian tekanan dan level air dalam boiler diharapkan mampu menjaga kondisi optimum boiler dan mencegah terjadinya kegagalan boiler. Variabel yang dimanipulasi pada penelitian ini yaitu dalam sistem multi-input multi-output (MIMO), yaitu laju alir air ke dalam boiler dan laju alir bahan bakar ke burner, sedangkan yang menjadi gangguan disini berupa laju alir steam. Dalam penelitian ini diambil tipe pengendalian Fuzzy Logic. Dengan menggunakan data desain boiler dan model matematis yang ada, disimulasikanlah sebuah model boiler dengan menggunakan MATLAB dan Simulink. Setelah dilakukan simulasi diperoleh nilai IAE pada persen disturbance +1% sebesar 72.42 (tekanan) dan 6.58 (level air), persen disturbance +3% sebesar 126.2 (tekanan) dan 11.47 (level air), sedangkan pada persen disturbance +5% sebesar 174.10 (tekanan) dan 15.83 (level air). Hasil yang diperoleh menunjukkan bahwa pengendali fuzzy dapat memberikan unjuk kerja pengendali yang cukup baik pada saat “digunakan penerapannya sebagai pengendali steam boiler yang melibatkan multi variabel.

Steam Boiler was an operating unit at a plant that plays an important role in producing steam in accordance with the needs of the various existing processes within the plant. At various processes within a plant, steam was used of course require pressure and temperature conditions that suit their needs. On the other hand, the quantity of supply of steam to each of these processes are not always the same depending on the needs of the process would be steam. Quantity varied needs of the plant must be a burden to the boiler for producing steam main tool. Control and pressure in the boiler water level was expected to maintain the optimum condition of boiler and prevent boiler failure. This research using multi-input multi-output (MIMO) system, where the manipulated variable were boiler feed water flowrate and fuel flow rate to the burner and disturbance variable was steam flow rate changes. In this research, fuzzy logic control used as controller and simulation using MATLAB and Simulink. After the simulation, IAE value with +1% disturbance were 72.42 (pressure) and 6.58 (water level), disturbance +3% were 126.2 (pressure) and 11.47 (water level), and disturbance +5% were 174.10 (pressure) and 15.83 (water level). The results obtained show that fuzzy controllers can provide the controller performance is good enough when used in its application as a steam boiler controller that involve multi-variable system.
