Abstract
Penelitian ini dilakukan untuk menganalisa material
komposit dengan matriks polypropylene berpenguat serat natural,
yaitu serat bambu betung dan serat rami untuk material absorpsi
suara. Tujuan penelitian ini adalah untuk mengetahui hubungan
perbedaan komposisi serat pada komposit dengan matriks
polypropylene terhadap nilai koefisien absorpsi suara (α) dan
morfologi dari material komposit diberikan, serta aplikasinya
dalam material absorpsi suara yang memenuhi standar ISO 11654.
Panjang serat yang digunakan adalah 10 mm dengan fraksi
volume 20% serat : 80% matriks. Terdapat 3 macam variasi
komposisi spesimen yaitu (5%B/15%R-PP), (10%B/10%R-PP),
(15%B/5%R-PP). Selain itu material juga akan diuji TGA
(Thermogravimetric Analysis) untuk mengetahui ketahanan
komposit terhadap temperatur. Metode pembuatan komposit yang
digunakan adalah hand lay up kemudian di panaskan dengan
oven. Metode pengujian yang digunakan berdasarkan standart
ASTM E1050, ASTM E2809 dan ASTM E1131. Hasil pengujian
menunjukkan bahwa spesimen (5%B/15%R-PP) memiliki nilai α
yang tertinggi pada sebagian besar rentang frekuensi, dan material
absorpsi tergolong material absorpsi kelas D menurut ISO 11654.
Hasil pengamatan dengan Scanning Elecron Microscope,
menunjukkan spesimen (5%B/15%R-PP) memiliki struktur
dengan pori paling banyak dibandingkan spesimen lainnya. Uji
TGA menunjukkan batas temperatur yang diperbolehkan untuk
aplikasi material R/B-PP yaitu sebelum material tersebut
mengalami degradasi massa yaitu dibawah 265oC.

This research was done to analize polypropylene
reinforced natural fiber composite material (bamboo and ramie
fiber), for sound absorption material application. The goal this
study is to understand the connection between the composition
difference of the polypropylene composite, sound absorption
coefficient (α) based on ISO11654 standard, and the morphology
of the composite material itself. The length of the fiber was 10
mm with the volume fraction 20% fiber : 80% matrix. There were
3 variation of the composition that used, (5%B/15%R-PP),
(10%B/10%R-PP), (15%B/5%R-PP). The materials have been
tested using TGA (Thermogravimetric Analysis) to find the
material endurance limit due to the temperature increase. The
making of the composite was using hand lay up methode, and
then heated using oven. The testing methode were using ASTM
E1050, ASTM E2809 and ASTM E1131 standard. The test result
indicates that the (5%B/15%R-PP) have a highest α at the most
frequency range, and the material was classified as D class
absorption material based on ISO11654. Obsevation result under
the Scanning Elecron Microscope indicates that specimen
(5%B/15%R-PP) have the most pores sturcture. The TGA test
indicates that the temperature limit alowed for the material to work is under 265 oC.
