Abstract

Natural fiber as a sound-absorbing biocompisite material is believed to not only reduce noise pollution but also to absorb heat. There are many underutilized coconut husks, which so far the use of coconut husks is only conventional. The focus of this research is to find the right solution in the use of coconut fiber as well as composite material engineering for technological purposes. The research method will use pure experiments using controlled specimens in the mechanical Engineering laboratory of ITB, including mechanicals tests, soundproofing. The results of he tensile test are the tensile strength of the largest coconut fiber composite fiber is found in the fiber volume fraction of 25% with a value of 59.072 Mpa, followed by 20% fiber fraction with a value of 59.025 Mpa, 15% fiber fraction with a value of 56.736 Mpa, fiber fraction 10% with a value of 56.807 Mpa, 5% fiber fraction with a value 53.736. and for he results of the soundproof test with frequency of 250 Hz – 2000 Hz at 5% fiber fraction, it has an absorption coefficient value of 0,03, 10% fiber fraction, has an absorption coefficient value of 0.18, 15% fiber fraction has an absorption coefficient value of 0.18. 0.18, the fiber fraction of 20 has an absorption coefficient of 0.22, the fiber fraction of 25% has an absorption coefficient of 0.28.
