Abstract
The limitations of machine size and cost are main problems for coffee harvesting using machine picking. Therefore, the prototype of Robusta coffee harvesting machine with portable and low cost was designed and created in this research. Moreover, the effects of bristle hardness, bristle size and brush rotation speed on the coffee harvesting efficiency were investigated. The experimental results showed that the prototype of portable Robusta coffee harvesting machine was effective to harvest the Robusta coffee. It provided the highest coffee harvesting efficiency of 75.24% by using the bristle hardness of 75 shore A, bristle size of 8 mm and brush rotation speed of 700 rpm. The bristle hardness, bristle size and brush rotation speed were significantly affected the coffee harvesting efficiency. The coffee harvesting efficiency was increased when increasing the bristle hardness from 60 shore A to 75 shore A and the brush rotation speed from 600 rpm to 700 rpm. On the other hand, the increase of bristle size from 8 mm to 10 mm provided the lower coffee harvesting efficiency.
