Analysis of Displacement with Variations in Brushless Motor Speed on an Oil Palm Frond Cutting System as a Drone Attachment

Harvesting oil palm is a critical activity in the plantation industry, but prolonged use of manual tools such as dodos and egreks often leads to health issues such as musculoskeletal disorders, repetitive strain injuries, and carpal tunnel syndrome. With advancements in technology, solutions like drones are increasingly being utilized to enhance efficiency in harvesting. This study aims to analyze displacement in relation to variations in brushless motor speed on an oil palm frond cutting system as a drone attachment. Tests were conducted at three motor speeds: 5700 rpm, 8200 rpm, and 9700 rpm, using three types of attachments—chainsaw, dodos, and egrek—at three different points: the gearbox (point 1), shaft pole (point 2), and drive motor (point 3). The average displacement values at motor speeds of 5700 rpm, 8200 rpm, and 9700 rpm were 0.068 mm, 0.089 mm, and 0.089 mm for the chainsaw; 0.785 mm, 2.158 mm, and 2.337 mm for the dodos; and 0.788 mm, 2.160 mm, and 2.364 mm for the egrek. The chainsaw demonstrated relatively smaller displacement compared to the dodos and egrek, indicating a higher level of stability when paired with the drone.
