Abstract

Wastes that we often encounter easily is waste from cigarette filters, one example of its utilization is the utilization of wast .filter. filter cigarettes as a composite mixture, by utilizing materials originating from waste which are easy to obtain by
 utilizing cigarette filter waste as a sound absorbing material. this study aims to
 determine the composition of the composite mixture reinforced by cigarette filter
 waste on sound intensity and sound absorption coefficient. The production method
 is with a fraction of 30%: 70%, 44%: 56%, and 51%: 51%, which is the best composite
 fraction with respect to sound intensity values and sound absorption coefficient
 values, composite materials with a frequency of 510 Hz get sound intensity values
 the highest is the 30%:70% fraction of 104,867 dBa. and the lowest is the 51%:49%
 fraction, which is 96.676 dBa, and the highest sound absorption coefficient is the
 51%:49% fraction of 0.196 and the lowest is the 30%-70% fraction, namely 0.129,
 so it can be concluded that the smaller the fiber fraction of the acoustic material of
 cigarette filter waste, the higher the sound absorption coefficient produced. The
 best sound absorption coefficient value is obtained for the material acoustic with a
 fraction of 51% :51% frequency of 510 Hz which is 0.196.
