DESIGN AND DEVELOPMENT OF AUTOMATIC REBUNG TOOLS USING VARIABLE FREQUENCY DRIVE BASED ON ARDUINO UNO

In chopping Rebung for the home industry, they still use conventional methods and lack application of technology. This, course, causes productivity quality industry products to be less than optimal. Productivity is influenced by several factors, including requiring workers more careful so that it requires a lot concentration, worker fatigue, which makes optimal in using time, workers' speed. Therefore, primary control system was made an automatic chopper based on VFD with Arduino Uno. The 3-phase induction electric motor used as prime mover blades (Variable Frequency Drive). For critical system, spring open pressing tube's lid servo buzzer monitoring medium. test uses adjust rotational speed motor. results show at frequency 20 Hz 147.8 rpm, produces chops length 3 cm 2 minutes 54 seconds. At 35 221.2 Rpm, chunks 1 minute 53 50 260.1 5 If done manually, takes average
