Identifikasi Parameter Akustik Permukaan Sumber dengan Metode Elemen Batas

Abstrak: Penentuan medan suara yang terjadi akibat radiasi sumber atau akibat hamburan gelombang suara merupakan salah satu permasalahan yang banyak diteliti oleh para peneliti akustik. Kasus seperti ini dapat disebut sebagai kasus langsung (direct problem). Kasus lain yang juga ditemui dalam akustik adalah kebalikan kasus langsung yakni penentuan parameter akustik seperti tekanan, kecepatan partikel atau impedansi akustik pada permukaan sumber berdasarkan informasi hasil pengukuran parameter akustik di titik-titik medan di sekitar sumber akustik. Kasus seperti ini dikenal sebagai kasus inversi (inverse problem). Solusi numerik yang digunakan pada tesis ini adalah Metode Elemen Batas. Kelebihan utama dari metode ini adalah penurunan dimensi masalah, karena hanya permukaan sumber akustik yang perlu didiskritisasi sehingga mengurangi dimensi persoalan yang dihadapi, misalkan persoalan tiga dimensi diselesaikan dengan perlakuan dua dimensi. Pada makalah ini disajikan solusi inversi dengan metode elemen batas untuk permasalahan radiasi akustik dalam domain akustik interior. Uji kasus radiasi melibatkan sumber akustik berbentuk kubus. Hasil perhitungan parameter akustik permukaan sumber dengan inversi metode elemen batas menunjukkan kesesuaian dengan nilai sebenarnya

Perluasan Kinerja Akustik Limbah Kayu Batang Kelapa Sawit Termodifikasi Bahan Formaldehida

Chemical modifications for waste oil palm trunks had carried out as acoustic material. This modification was conducted in two stages. Firstly, formalization with formaldehyde solution and secondly is impregnation with melamine-formaldehyde resin. Formalization was conducted in alkaline condition (pH 10) for 3 days and 5 days. Impregnation was carried out under pressure 3 bar and 5 bar and held for an hour. For completed these modification, the samples was cured at 120oC for 10 minutes and then dried at (103±2)oC to reached moisture content of less than 6%. This modification has changed the chemical structure and the morphology of wood, as shown by the FTIR and SEM results. The samples became denser, stronger and more rigid. Furthermore, the mechanical and physical properties of modified wood are also increasing. The absorption coefficient decreases with increasing formalization time and impregnation pressure. Based on trend of absorption coefficient, BKS wood can be applicated as resonant absorber with work class from A to class B and D
