Abstract

Telah dilakukan penelitian kenyamanan akustik yang dilakukan pada ruang kelas dengan memanfaatkan limbah sebagai bahan untuk membuat material akustik. Pada penelitian ini bahan yang digunakan adalah berasal dari limbah kardus yang sudah tidak terpakai sehingga selain untuk memperbaiki kualitas akustik pada ruangan, penggunaan kardus sebagai bahan peredam juga dapat mengurangi limbah pada lingkungan. Pada penelitian ini diperoleh hasil koefisien serap bahan dari limbah kardus adalah 0,57 dengan intensitas bunyi 90 dB dan variasi frekuensi 125 Hz, 250 Hz, 500 Hz, 1KHz, 2 KHz, dan 4 KHz. Dengan hasil koefisien serap sebesar 0,57 dapat memperbaiki tingkat kualitas akustik pada ruangan. Hal ini dilihat dari data hasil pengukuran 3 aspek kebisingan yaitu bising latar belakang, tingkat tekanan bunyi dan waktu dengung pada ruangan yang mengalami penurunan nilai kebisingan setelah dilakukan pemasangan material akustik pada dinding ruangan, sehingga kualitas akustik pada ruang kelas dapat dikatakan nyaman dan sesuai dengan standar SNI.
