Abstract

This research aims to design an acoustic enclosure combined with coconut fiber to reduce the level of external noise generated by the portable generator. The study conducted with measuring the noise level in the generator before and after installing acoustic enclosure. The experiment has done with measuring the noise level of the generator before and after pairing the enclosure. Measurement of noise level has done according to ISO standard.Measurements are made five times in each point, the data shown is the average value of the measurement results. Then noise level data is displayed in table form and noise contour. Enclosure made using steel plates with a thickness of 3 mm and coconut coir fiber sheet of thickness of 35 mm. The results show that noise levels after installing with enclosure acoustic less than 70 dB. The noise level of the portable generator was 91.20 dB before covering with acoustic enclosure. Experimental results show that the use of enclosures combined with coconut fiber can lower the noise level of the portable generator. The use of coconut fiber in the acoustic enclosure is expected to replace the use of industrial acoustic materials. So, the public can make a cheaper acoustic enclosure
