Abstract

This study was conducted to develop the mechanical properties of the rice straw board as the building material. All the three samples were made up with same composition of 80% of low density polyethylene (LDPE) and 20% of the rice straw but different in pre- heating temperature which are 160 °C, 170 °C and 180 °C. The sample are being tested using three different test which is hardness test, tensile test and thermal conductivity to determine the mechanical properties of the rice straw board. Through this study, it can be concluded that sample with 180 °C of pre-heating temperature has the most suitable composition that can be applied as a building material. The rice straw board has the highest hardness, 42 with the lowest value of the thermal conductivity, k, 0.4858 W/mK. Furthermore, it also havethe maximum load that can be applied to the sample, 167.623 N and also have the highest value of tensile stress, 4.298 MPa
