Coco shell is waste that spread all over Indonesia, especially in Surabaya. Coco shell is rarely utilized, thus create a lot of waste. Recently, coco shell waste has been gaining popularity because of its unique and strong shape. A lot of craft man has been using coco shell as a decoration. Coco shell unique shape has been utilized into coconut mosaic; a furniture decoration. This research will utilize coco shell as an acoustic tile, specifically resonator, so that coco shell has a better value. Coco shell used will be a young coco shell, since it's a rarely utilized waste. The resonator will be tested in regard of its ability to absorb and scatter sound. The test will be using ISO 354 [1]. The objective of this research is to make a resonator that not only have a value in room acoustic, but also special aesthetically pleasing. Room acoustics prefers to any room that need a treatment regarding acoustics, as in music studio room, broadcasting room, praying room, home theatre, music room etc.
