SOUND PROOFING PANEL MADE FROM PATCHWORK AND GYPSUM AS A GREEN MATERIAL INNOVATION
Jogjakarta as a student city and tourism has become a target for investors to invest their capital. Hotels, housing, apartments, shop houses, malls, and many other new buildings were built in Jogjakarta. One effort to support the environmental-friendly building movement is to develop new materials that can support environmentally friendly development itself. Composite materials with silencer properties can be considered to be developed into building materials. Composites that use industrial waste materials are one of the innovations in building materials. At present, the garment industry in Indonesia leaves traces of patchwork waste that is stacked/ignored. Fabrics are materials that have sound muffling capabilities. The character of the fabric that is capable of absorbing the fabric of patchwork can be processed into sound absorption material. This article compares the dampening effect between patchwork panels and patchwork composites. Patchwork experiments are used to be processed and developed into building materials that can reduce indoor noise. The results of this study are patchwork material which is arranged in layers and is considered capable of reducing noise and is a green material alternative.
