Abstract

Oil Palm frond wastes that are stacked in the rows between oil palm plants take a long time to decompose. To accelerate the decomposition, oil palm leaves need to be chopped into small size and the palm frond need to be compressed into flat. This research aims to design and analyze the performance of an integratedmachine for chopping oil palm leaves and compressing fronds. The design of the machine is performed using engineering characteristics of palm leaves and fronds. The machine consists of palm leaf cutting unit, palm compressing unit and palm leaf chopping unit. All units are integrated and powered by a diesel engine. The leaf cutter used circular blades, the frond compressor used two pairs of grid-rolls and the leaf chopper used a reel-bed knife. All units were tested in order to obtain the machine capacity, percentage of leaves cut, percentage of reduction and increase in frond dimension and chopping leaves size. Leaf cutting unit was tested at blade speeds of 480, 640, and 800 rpm. The compressing unit was tested at rollers speeds of 70, 90, and 110 rpm. The chopping unit was tested at blade speeds of 800, 1200, and 1600 rpm. The test results showed that the optimum machine capacity was 207 frond/h (equal to 1.97 ton/h), leaf cutting was 83.01%, frond height decrease was 18.18 %, fronds width increase was 41.20%, and chopping leaves length and width were 23.3 mm, 3.20 mm, respectively. The optimum operation condition was achieved at cutting blade speed of 640 rpm, 110 rpm compressing rolls speed, and 1600 rpm chopping blade speed.
