Abstract

This study aimed to identify the effect of stirring speed on the mechanical and morphological of particulate powder of rice husk burning results using variation of stirring speed at 660 rpm, 885 rpm and 1020 rpm. The material used in this research was particles of rice husk burning with the matrix as Epoxy Resin Bakelite EPR 174 and Epoxy Hardener V-140 and the method used in composite making process was hand lay up. The result of composite the tensile test showed the lowest strength was at 665 rpm with the value of 36,544 MPa and at 1020 rpm rotation variation had the highest tensile strength equal to 39,064 MPa. For the impact test, the lowest absorption energy was found on the 660 rpm stirring variation of 0.85 Joules and the 885 rpm stirring variation generated the largest absorption energy of 14,992 Joules. The results of particle composite morphological testing with a variation of 885 rpm rotation indicated a fracture breakdown that occurred due to the equitable distribution of the particles.
