Descripción
The innovation of parallel strand lumber (PSL) from oil palm trunk waste was intended to develop alternative raw materials other than wood as well as improve the characteristics of the oil palm trunk. This study aims to analyze the effect of soaking duration on the phenol-formaldehyde adhesive solution to the characteristics of PSL. Variations of soaking duration used in this study were 30, 60, 90, and 120 minutes. The results of this study showed the modulus of elasticity (MOE) ranged from 53.7 × 103 to 103.2 × 103 kg/cm3 while the modulus of rupture (MOR) ranged from 358 to 596 kg/cm2 . The compressive strength ranged from 301.86 to 439.96 kg/cm2. The hardness of horizontal, vertical, and parallel grain ranged from 439.17 to 747.41 kg/cm2 , 361.86 to 526.01 kg/cm2, and 285.09 to 451.09 kg/cm2, respectively. The best quality of PSL which was soaked in a phenol- formaldehyde adhesive solution for 120 minutes. It can be concluded that oil palm trunk waste can be utilized to substitute the wood for lightweight construction material and support the development of green material.
