Abstract

Noise at the airport can be reduced by building materials that can dampen sound in the form of acoustic boards. One of the natural materials that has potential as a candidate for acoustic sound dampening board material is corn cobs. This study will determine the effect of the volume fraction of corncob powder on the quality of the composite acoustic board. The volume fraction variations studied were 0%, 45%, 55% and 65% corncob powder. The quality of the acoustic board reviewed only includes sound attenuation capabilities in the form of Noice Absorption Coefficient (NAC) values and bending strength. Acoustic board production process using the Hand Lay-Up method. This study concluded that the addition of corncob powder to epoxy resin (range 0% -65%) can increase the sound attenuation ability. The best dampening ability is found in composites reinforced with 65% corn cob powder with a Noice Absorption Coefficient (NAC) value of 0.275 at a frequency of 160 Hz, according to ISO 11654:1997 standards. In addition, the addition of corncob powder to epoxy resin (range 0% -65%) can increase bending strength. The best bending strength of the 65% variation of corncob powder was 17.91 MPa. The best volume fraction variation is the composition of 65% corncob powder.
