Abstract
Peningkatan kepadatan penduduk dan aktivitas perkotaan menyebabkan meningkatnya tingkat kebisingan serta kebutuhan pendinginan bangunan, sehingga diperlukan material yang mampu memberikan kinerja akustik dan termal secara bersamaan. Salah satu alternatif yang berpotensi dikembangkan adalah panel termo-akustik berbasis limbah egg tray dan sekam padi yang ramah lingkungan. Penelitian ini bertujuan menganalisis pengaruh variasi komposisi egg tray dan sekam padi terhadap karakteristik fisik, sifat termal, dan kinerja akustik panel termo-akustik. Panel difabrikasi menggunakan lima variasi komposisi, yaitu 100:0, 75:25, 50:50, 25:75, dan 0:100, serta satu panel sandwich dengan perbandingan 1:1 menggunakan perekat lem kayu. Karakterisasi dilakukan melalui pengujian densitas, porositas, konduktivitas termal, Sound Transmission Loss (STL), dan koefisien absorpsi suara menggunakan tabung impedansi. Hasil penelitian menunjukkan bahwa peningkatan proporsi sekam padi menurunkan densitas panel dari 0,2757 g/cm³ menjadi 0,1898 g/cm³, meningkatkan porositas dari 29,49% menjadi 35,52%, serta menurunkan konduktivitas termal dari 0,1269 W/m·K menjadi 0,1009 W/m·K, sehingga kemampuan panel sebagai isolator panas semakin baik. Pada karakteristik akustik, nilai koefisien absorpsi suara tertinggi diperoleh pada sampel ETSP-3 dan ETSP-4 pada frekuensi 1400 Hz dengan koefisien absorpsi mencapai 0,98, sedangkan nilai STL tertinggi diperoleh pada sampel ETSP-1 pada frekuensi 3000 Hz dengan nilai sebesar 13 dB. Hasil tersebut kemudian direpresentasikan menggunakan parameter Noise Reduction Coefficient (NRC) dan Sound Transmission Class (STC). Peningkatan kandungan sekam padi meningkatkan kemampuan penyerapan suara dengan nilai NRC tertinggi sebesar 0,442 pada variasi ETSP-4. Sebaliknya, kemampuan insulasi suara menurun, ditunjukkan oleh nilai STC yang berkurang dari 11 pada ETSP-1 menjadi 2 pada ETSP-5 akibat menurunnya massa permukaan panel. Secara keseluruhan, panel berbasis egg tray dan sekam padi berpotensi dikembangkan sebagai material penyerap bunyi dan isolator panas ramah lingkungan, terutama sebagai lapisan tambahan (lining) pada sistem dinding komposit.

The increasing population density and urban activities have led to higher noise levels and greater building cooling demands, creating the need for materials that simultaneously provide acoustic and thermal performance. One promising alternative is thermo-acoustic panels fabricated from environmentally friendly waste materials, namely egg trays and rice husks. This study aimed to investigate the effect of varying egg tray and rice husk compositions on the physical characteristics, thermal properties, and acoustic performance of thermo-acoustic panels. The panels were fabricated using five composition ratios (100:0, 75:25, 50:50, 25:75, and 0:100), along with one sandwich panel with a 1:1 composition bonded using wood adhesive. Characterization was conducted through density, porosity, thermal conductivity, Sound Transmission Loss (STL), and sound absorption coefficient measurements using an impedance tube. The results showed that increasing the proportion of rice husk reduced the panel density from 0.2757 g/cm³ to 0.1898 g/cm³, increased the porosity from 29.49% to 35.52%, and decreased the thermal conductivity from 0.1269 W/m·K to 0.1009 W/m·K, thereby improving the panel's thermal insulation performance. In terms of acoustic characteristics, the highest sound absorption coefficient was obtained by ETSP-3 and ETSP-4 at 1400 Hz, reaching a value of 0.98, while the highest STL value was achieved by ETSP-1 at 3000 Hz with an STL of 13 dB. These acoustic characteristics were further evaluated using the Noise Reduction Coefficient (NRC) and Sound Transmission Class (STC). Increasing the rice husk content enhanced the sound absorption performance, with the highest NRC value of 0.442 achieved by ETSP-4. In contrast, the sound insulation performance decreased, as indicated by the reduction in STC from 11 for ETSP-1 to 2 for ETSP-5, due to the decrease in the panel's surface mass. Overall, egg tray–rice husk-based panels demonstrate considerable potential as environmentally friendly sound-absorbing and thermal insulating materials, particularly as lining layers in composite wall systems.
