PEMILIHAN SALURAN ENGINE STAND UNTUK MEREDUKSI KEBISINGAN

Abstract

Abstract: This research sets out to acquire the overall description of noise caused by the engine stand, which is made of pipe and bamboo, and the rate of its reduction. The object for this research is two premium engines located in the State University of Malang. The selected engine stand is mounted by an outtake made of pipe and bamboo before it is ignited. The analysis method used is descriptive approach complemented by Anova technique. The result shows that the noise range of engine stand are: 72 dBA to 78 dBA in rotation of 800 rpm, 78 dBA to 79 dBA in rotation of 1500 rpm, and 88 dBA to 89 dBA in rotation of 2500 rpm before the pipe outtake is mounted; meanwhile, after the pipe outtake is mounted the result shows the range of 69 dBA to 71 dBA at 800 rpm, 75 dBA to 76 dBA at 1500 rpm, and 85 dBA to 87 dBA at 2500 rpm. For the bamboo outtake, the result shows the range of 68 dBA to 69 dBA at 800 rpm, 72 dBA to 75 dBA at 1500 rpm, and 86 dBA to 88 dBA at 2500 rpm. This overall result shows significant difference with P = 0,000 for each rotation (rpm); the usage of pipe and bamboo outtake can reduce the noise.
