Abstract
Komposit berpenguat nano filler merupakan satu material yang sedang dikembangkan. Salah satu aplikasinya dapat digunakan untuk menyerap suara. Sedangkan Barium Heksaferrit merupakan material yang memiliki sifat magnetik yang baik yang dapat menyerap gelombang elektromagnetik. Penelitian ini menggunakan silicone rubber berpori sebagai matriks, nanoselulosa dan barium heksaferrit sebagai filler. Variabel yang digunakan pada penelitian ini adalah penambahan Barium Heksaferrit dan tanpa penambahan Barium Heksaferrit. Tujuan dari penelitian ini adalah menganalisis pengaruh penambahan nanoselulosa dan Barium Heksaferrit terhadap nilai koefisien absorbsi suara dan nilai penyerapan gelombang elektromagnetik. Pengujian yang dilakukan dalam penelitian ini meliputi uji koefisien absorpsi suara, SEM, TEM, FTIR, densitas, dan uji VNA. Silicone Rubber berporous yang mengandung 6% nanoselulosa dan 10% BaM memiliki nilai α tertinggi 0.4762 pada frekuensi 4000 Hz dan nilai rugi refleksi tertinggi yaitu 23.016 dB pada frekuensi 8.39 GHz.

Composite materials reinforced by nanofiller are now
becoming one of the developed materials. It can be used as an
acoustical material. Acoustical materials are often used as sound
absorber. Meanwhile, barium hexaferrite is a material that has
good magnetic properties which can absorb electromagnetic
waves. This study used porous silicone rubber as the matrix,
nanocellulose and barium hexaferrite as the filler. The variables
used in this study were the addition of barium hexaferrite and
without the addition of barium hexaferrite. The purpose of this
research is to analyze the effect of nanocellulose and barium
hexaferrit to the value of sound absorption coefficient and the
value of electromagnetic wave absorption. Tests performed in this
study were included sound absorption coefficient, SEM, TEM,
FTIR, density and VNA test. Porous silicone rubber which
containing 6% nanoselulosa and10% BaM has highest α value
0.4762 at frequency 4000 Hz and highest reflection loss
value -23.016 dB at frequency 8.39 GHz.
