Effendi Arsad

Abstract


Acacia Mangium wood can to used for substitution comercial wood. Materiel Acacia mangium woods  was take from HTI at  seven age with diameter   30 – 33 cm.   The results Physical properties and mechanical strength obtained by the water content of dry air from 13.78 to 14.89%; density of 0.60 to 0.62 gr/cm3; specific gravity of 0.59 to 0.61; compressive strength parallel fibers from 319.54 to 361.70 Kg/cm2; compressive strength perpendicular to fiber 117-197 kg/cm2; bending strength (MOR) from 509.25 to 680.50 kg/cm2; cleave strength 80.25 to 110.90 kg/cm2; tensile strength of 98.27 to  133.03 kg/cm2; shear strength of parallel fiber from 93.53 to 149.43 kg/cm2 and hardness from 453 to 565 kg/cm2.  Physical properties and mechanical  strenght  can was  standard  for furniture and  construction.

Keywords: acacia mangium wood, physical  and mechanical  wood
