Abstract

Semi-automatic rambutan boring machine were developed with dimensions of the machine 80 x 170 x 100 cm. The semi-automatic rambutan boring machine was powered by Motor Ac 220 Volt 0.25 kW and transmitted power to a 1:60 reduction gear, driving a chain with 20 sets of rambutan transport with a diameter of 40 mm to transport the rambutan to the seed drill set, size 18 mm. The drilling system was a 4 bar air pressure pneumatic, and the Geneva sprocket controlled the drilling range. The average rambutan boring capacity was 3,185 fruits h-1, and variability of rambutan seed boring speed, rambutan diameter, rambutan height, rambutan weight, rambutan seed diameter, rambutan seed height, rambutan seed weight, rambutan peel, and rambutan seed boring ability were 1.13±0.54, 44.04±2.78, 60.60±3.83, 21.39±1.35, 8.60±0.54, 17.01±1.07, 5.41±0.34, 2.62±0.16 and 69.44±4.39, respectively. The efficiency of the semi-automatic rambutan boring machine was 95.75%, with a machine payback period of 140 days and a break-even point of 288.2 h year-1
