		abstract={Coal feeder system is one of the most important systems in a steam power plant. This tool is used to supply coal fuel from coal bunkers to boilers. This tool is equipped with a variable vrequency drive (VFD) that works in accordance with its function, namely to regulate the speed of the motor drive belt coveyor so that the coal that supplies the boiler can be regulated in number, so that the process of forming heat in the boiler can run well and efficiently. VFD has a setting of 4mA-20mA so that the motor rotational speed can be varied according to these settings, and cause the amount of coal that can be transported per hour also varies depending on the motor rotational speed. From the research, it is found that the 4FA VFD setting of the motor speed produced is 0Rpm so that coal that can be transported is 0 Ton / hour. Whereas at the setting of 20mA the speed of the motor produced is 1500Rpm so that coal that can be transported is 18.27Tons / hour.}
