Abstract

this research was conducted to develop granular organic fertilizer composer. the machine produces organic fertilizer in granular form so that can be carried an applied to the land easier. the machine was designed to have capability to process organic materials that available around the agricultural area in order to overcome the problem of shortage of fertilizer. this study used functional and structural approach. technical data of the machine was 60x80x140x in dimension, the 24 hp engine that attached to the machine has speed 1200 rpm, the transmission was 1 : 6 and 188 kg by weight. performance test showed the following result; effective capacity for granulation was 409.94 kg per hour at 198.2 rpm; it produced granular 6 mm in diameter mm and 6-10 mm in length, motor power used was 3.052hp which generate noise level 97.4 dB so that operators can operate the machine for 3 hour without having a bad influence on them. the result of economic analysis engine got value cost of good- Rp35.34/kg; break even point = 4013,067kg per year; BC ratio = 1,414 and NVP = 28,4746 milion. this resarch expected could spur the development of organic fertilizer and agricultural mechanization industry in west sumatera and alaso creating new job for the community
