Abstract
The production of organic fertilizer was still constrained by low crushing capacity, especially for paddy straw. This material has not been utilize optimally for organic fertilizer. Paddy rice harvest index is about 0,5, meaning paddy rice plant produced straw as much as 50 percent of the total material which was yielded by paddy plantation. It is a potential source for organic fertilizer. The problem is that farmers could cut it into small piece in high capacity. Several machines have been designed to solve this low capacity but many trouble operations found by these machines. In this research, the knives were replaced by rotary saws. These rotary saws were connected to the shaft by screw mode. The objective of this research was to create a capable machine that could crush the paddy straw and overcome the disadvantage of previous machines. Another objective was to get the yield as small as possible so the decomposition process will run rapidly. This research used an engineering design method. It was conducted through 5 steps; they were Definition of the problem, Gathering of information, Generation of alternative solutions, Evaluation of alternatives and decision making, and Communication of the results. The designed machine was drawn into technical drawing and then fabricated it at the Agricultural Engineering Workshop. The rotary saws were rotated by a 7.5 hp-diesel engine. The material capacity was 190.6 kg per hour at 1400 rpm while the fuel consumption was 0.85 L/hour. In conclusion, the shaft to shaft transmision could be applied to the rotary saw crusher with a lighter fibration and smaller size. Keywords: rotary saws, paddy straw crusher, organic fertilizer
