This study, Development of a Coconut Midrib Separating Machine for Local
Broomstick Production aimed to reduce manual labor, improve production
efficiency, and support small scale broom sticks producers through the application
of mechatronics technology. The developed prototype combines mechanical,
electrical and electronics control systems to motorize the stripping process of
coconut midribs. The machine consists of a stripping mechanism powered by AC
and DC motors, control components including start, stop, and emergency stop
functions. Both functionality and performance test were conducted to assess the
machine’s feeding capacity, stripping efficiency, weight sensor accuracy, power
consumption, and motor efficiency. Results showed that the machine successfully
attained its stripping ability. The highest production rate was up to 98 pieces of fresh
coconut leaves under 30 minutes in optimal operating conditions. Power
consumption varied depending on load quantity and operating time with an average
power consumption of 0.2669 kWh and 0.00813 kWh for each motor, while the
machine maintained stable performance throughout testing. Although the coconut
midrib feeding capacity is from five (5) to eight (8) pieces only due to the narrow
feeder section, the machine can operate rigorously for hours without motor
overheating. Findings indicate that the developed machine can serve as a practical
and reliable solution for larger local broomstick production, helping reduce physical
effort and improve productivity among local and small-scale producers.
