Abstract
The need for good materials requires scientists to use natural and artificial material waste to be processed into more useful things. Variations in NaOH treatment are without immersion, 5%, 10% and 15% NaOH. Large percentage of fusion uses volume fraction with teak powder by 65% and pine resin matrix by 35%. The size of teak wood powder used is 8 mesh ? a ? 7 mesh. Noise absorption testing using two microphone impedance tubes with ISO 10534-2: 1998 and ASTM E:1050:1998 standards. The tensile test is performed with a tool with astm standard D 638-03. The results of the test obtained the highest sound absorption strength in specimen concentrations of 5% NaOH with a value of 0.69 at a frequency of 300 Hz. The maximum pressure value and also the highest strain are at the concentration of 5% NaOH of 4.28 MPa and 5.00%
Keywords : NaOH, Teak Wood Powder, Pine Resin, Biocomposite
