    PLTU or power plant is one type of electrical produced utilize fuel combustion in boiler to heat the water and changed the water into steam. Furthermore, the use to drive steam generator. In industrial power plant, stability requires the stability of electricity supply in the process of generating the electricity supply is often for the consumer, the system disturbance caused by a sudden load spikes or because of other factors. So that the control system is needed to maintain the stability of process variables (temperature, pressure, flow rate, etc.). Control Unit or coordinated control system has a role to control the boiler and turbine generator unit as to respond according to the setpoint load changes while keeping all operating parameters on optimal conditions and within safe limits. Control unit is operated in a coordinated mode, boiler follow mode, turbine follow mode and manual. In this final project, we create a simulation of the main steam pressure control system in boiler. This final project simulates a control unit in turbine follow mode and coordinated mode. In the coordinated mode, the change of load (MW) causes changes in the turbine master and boiler master, in this final project only turbine master is used. While the turbine follow mode, manually set the boiler master , in this final project is a major pressure on the boiler is set manually by changing the setpoint values. From the experiment data, an open-loop mode provides good response. When the difference between setpoint and process value of the output changes more quickly and when the difference equal to zero then the output stops at the last value. Error value changes in the value of CO at 0.04. In close loop mode changed CO error of 10%. This simulation does not give exact figures but the actual data can give nearly the same response with the actual conditions of error at 10% in coordinated mode and 12 % in tirbine follow mode. Key words: steam, pressure, Control Systems, a control unit
