KARAKTERISTIK PAPAN PARTIKEL TANPA PEREKAT DARI KAYU PULAI (Alstonia scholaris)
Keywords:
Pulai (Alstonia scholaris), particleboard, oxidant, FeSO4Abstract
Pulai (Alstonia scholaris) is a fast-growing species coming from community forests. Most of the tree parts, namely stem, bark, fruits and roots, have enormous benefits. Especially for the stem, it has the potential to be developed into forest products include particleboard without adhesive. This study aimed to analyze the characteristic properties of the particleboards without adhesive (physical and mechanical properties of the boards) at various levels of oxidants. Particleboards with a size of 30 cm x 30 cm x 0.7 cm and a target density of 0.75 g/cm3 were manufactured through particle activation with H2O2 and FeSO4 at various level of consentration. The board were hot pressed at 180oC with pressure of 25 kg/cm2. Physical and Mechanical properties of boards were evaluated based on Japanese Industrial Standard (JIS) A5908 2003. The results showed that the optimal oxidant consentration of H2O2 and FeSO4 from the parficleboards made was 20% and 5%, respectively, because its physical and mechanical properties fulfilled JIS standard
