Rancang Bangun Alat Pencacah Tembakau Otomatis Berbasis Plc Dan Scada

Abstract

Tobacco leaf chopping still uses the traditional method which is assisted by a motor that drives the blade to rotate, but the speed that cannot be adjusted. Therefore, an automatic tobacco chopper based on PLC and SCADA was created. This machine uses a blade that is driven by a 3 phase 0.5 PK AC motor which can be controlled manually using VSD and automatically using PLC and is also capable of monitoring and controlling using SCADA. In this chopping process using tobacco leaves that are still wet. This machine is equipped with an inverter whose acceleration can be adjusted so that the starting of the motor can be done in a soft start and braking can work optimally and efficiently. The  results within one hour using a frequency setting between 15 to 35 Hz, a maximum of 116 kg of chopped tobacco leaves is produced with a thickness of 1 to 2 mm. The higher the frequency setting, the higher the RPM value where this RPM will determine the total capacity of the chopped tobacco
