Abstract

Indonesia has a majority of hardwood species. Each wood has different strength and stiffness values between one wood and another, and to decide the strength and safety of the structure,and the wood must be tested or measured first in a non-destructive manner, which is commonly called wood sorting. To support research on sorting, visual sorting and mechanical sorting methods are used on hardwood. This research is based on SNI, the research was executed in the laboratory of Civil Engineering in Muhammadiyah University of Surakarta and in order to obtain representative results, 5 test specimens were made for testing compressive strength parallel to grain, 5 test specimens for compressive strength perpendicular to the fiber, 5 test specimens for tensile strength parallel to the grain, 5 test specimens for tensile strength perpendicular to the grain, 5 test specimens for flexibility strength and modulus of elasticity, and 5 test specimens for shear strength. The results of the research that has been executed on jati and keruing wood types concluded that the percentage value of strength for visual sorting is only 23% of the strength value of mechanical sorting. And in terms of strength ratio, teak wood is slightly superior with an average ratio of 0.55 and keruing wood with an average ratio of 0.53.
