Abstract

Kebisingan dapat mempengaruhi kenyamanan saat berkendara. pembuatan interior penumpang haruslah menggunakan material yang dapat mengabsorbsi suara. Penelitian ini bertujuan untuk menganalisa pengaruh pembahan serat bambu betung 5, 10, dan 15% pada material komposit unsaturated polyester untuk penyerapan suara pada bagian mesin kendaraan. Permasalahan yang dikaji untuk mengetahui nilai koefisien absorpsi suara, sifat fisik, sifat mekanik dan ketahanan termal serta proses manufaktur. Komposisi fraksi massa serat yang digunakan adalah 5%, 10%, 15%. Pengujian yang dilakukan adalah pengujian FTIR, absorbs suara, SEM, densitas, Flexural, dengan tujuan untuk mendapatkan nilai koefisien absorpsi suara terbaik serta sifat fisik dan pembuatan prototype. Metode yang digunakan berdasarkan standard ASTM E 1050 untuk pengujian absorbsi suara. Dari hasil pengujian didapatkan nilai koefisien absorpsi suara tertinggi 0.502 pada frekuensi 4000 Hz. Nilai tertinggi didapatkan pada komposit dengan presentase 15% serat bambu betung dan 85% unsaturated polyester. ================================================================================================ Noise can affect the comfort in driving. Therefore, the interior should be made by sound absorption materials. Objective of this research was to analyze betung’s bamboo fibre reinforced polyester composite for sound absorption used in the machine part of the vehicle. The problem was to find out the composite morphology, value of sound absorption coefficient, flexural strength, thermal stability and manufacturing process. by comparing variation of composition reinforcement and matrix. The composition of the mass fraction of the reinforcement used were 5%, 10%, and 15%. The goal was to find out the best sound absorption coefficient value, good physical and the prototype. The methods were based on ASTM E1050 for sound coefficient absorption test.. From the results was obtained the sound absorption coefficient, flexural strength, and density were, 0.502 at 4000 Hz frequency, The highest value was obtained on composite with percentage of 15% Dendrocalamus Asper Fiber and 85% Unsaturated Polyester.
