A series of study to explore possibility in using paddy-straw as main material to construct cheap and high quality panels has been developed. Prior to this study, laboratory research to examine strength of compression and tensile of the panels have been conducted, which is showed a significant value for a non-structural panel. The compression is 15 N/mm2 and tensile averaged at 0,5 N/mm2 . In this study, acoustic properties of the panels is to be examined, i.e.: transmission loss (TL), absorption coefficient (), and reverberation time (RT60). The test showed TL of 10 dB and 16 dB, of 0,4 and 0,8 and improve RT60 from 0,88 sec to 0,35 sec and 0,16 sec (500 Hz is used for reference). Abstract in Bahasa Indonesia: Ketersediaan panel pelapis dinding yang bersifat akustik dengan harga yang lebih terjangkau seperti yang terbuat dari bahan limbah sangatlah penting. Pada penelitian awal telah diselidiki penggunaan jerami sebagai bahan baku pembuatan panel akustik, sekaligus telah dilakukan pengujian terhadap kareakteristik struktural (uji desak dan lentur) dari panel tersebut. Dari uji kekuatan struktural, panel memiliki kekuatan desak mencapai 15 N/mm2 dan kuat lentur reta-rata 0,5 N/mm2. Kekuatan ini dianggap mencukupi bagi panel non-struktural yang hanya bertugas untuk memikul beban sendiri. Oleh karena tujuan awal pembuatan panel adalah untuk kepentingan akustik, maka pada penelitian lanjutan, dilakukan uji laboratorium dan lapangan untuk melihat karakterisktik akustiknya. Adapun pengujian meliputi: redaman/insulasi (TL), koefisien serap () dan waktu dengung (RT60). Dari hasil pengujian, panel mempunyai TL 10 dB dan 16 dB, 0,4 dan 0,8, serta mampu memperbaiki RT60 ruangan dari 0,88 detik menjadi 0,35 detik dan 0,16 detik. Kesemua pengujian menggunakan band frekuensi 500 Hz sebagai acuan. Kata kunci: panel jerami, insulasi, koefisien serap, waktu dengung.Downloads
