dc.description.abstract | Kebisingan di sekitar bangunan yang terus meningkat serta naiknya permintaan bahan bangunan yang bersifat akustik untuk kebutuhan ruang music dan film di dalam rumah (dikenal dengan istilah Home ·theatre). Telah menyebabkan kebutuhan bahan bangunan yang bersifat akustik juga meningkat. Namun, bahan semacam ini tidak secara merata terjangkau masyarakat.Pemanfaatan bahan limbah, seperti ijuk aren, sabut kelapa dan Polyurethane sebagai bahan baku pembuatan material akustik. Dimana selain kita mudah mendapatkan limbah ijuk aren, sabut kelapa mudah otom.at.is harga dari suatu bahan material tersebut dapat terjangkau oleh masyarakat kalangan menengah ke bawah. Material yang berpori, berserat dan lunak pada wnumnya merupakan jenis material dengan sifat penyerap bunyi yang baik. Noise around buildings continues to increase and increase demand for acoustic building materials for music rooms and films at home (known as Home theater). Has caused The need for acoustic building materials is also increasing. However, materials This kind of thing is not evenly affordable by the community. Utilization of waste materials, such as palm fiber, coconut fiber and polyurethane as raw materials for making acoustic materials. Apart from that, we can easily get palm fiber waste and coir coconut is easy otom.at.is the price of these materials can be affordable by lower middle class society. Porous, fibrous and soft material In fact, it is a type of material with good sound absorbing properties. | en_US |
