Abstract

Abstract. The natural wealth of Indonesia produces a wide range of natural resources. This research will discuss sawdust and coconut fibre for example from natural resources which can be processed into building materials. The use of the absorber as a facade is needed, especially for buildings located in noisy urban areas. Various research has studied the absorber made from sawdust and coconut fibre, but only a few studies that study the absorber material that has the texture of waffle on its surface. The research method used is the method comparisons of the value of the absorption coefficient, density and Sound Transmission Loss (STL) impedance tube with 1/3 octave filter. The result is that the waffle the panel from the sawdust has a higher density than waffle the panel from coconut fibre. The value of the coconut fibre panel STL ranged 46,134 – 51,312 dB. This value is lower than the STL material from sawdust that has a value between 47,301 – 62,688 STL. Absorption coefficient, coconut fibre panels between 0,432 – 0,511, while the value of the coefficient of absorption sawdust panel range 0,469 – 0,529. (max 200 words).
