Abstract
Abundant resouce of coconut fiber in a small vilage in Kulon Progo, Kadigunung haven-t been used before this research. Even though it can be used to become raw material organic fertilizer for agriculture that most of the population member are making a living as a farmers. But there is a problem when processing to make the fertilizer, it is the use conventional maner to crush the coconut fiber. So needed appropriate technology, namely crushing machine. The design of crushing machine uses a drive gasoline engine with the power 5.5 HP and the spin is 2,000 rpm. The blades amount to 21 moved and 12 fixed blades. It was measured by digital tachometer and sound level meter. And the others analysis were doing by formula calculating. The results of this research invove fuel consumption, depreciation of raw coconut fiber, noise level, linier v-belt velocity, and rpm of the blade shaft. They were resulted 1,800 cc, 0.05 kg, 99.3 dB, 2π m/s, and 10,595 rpm. That can be infered in the of this crushing machine is good performance.
