Daftar Isi:
- Binderless particleboard is an alternative product to optimize the biomass potential of mangrove plant in Indonesian, such as nipa frond (Nypa sp.). Considering the difference characteristic between inner and outer part of nipa frond, this research used both parts as raw materials for binderless particleboard. This research aimed to analyze the interaction between composition factor and pressing temperature factor on physical and mechanical properties of binderless particleboard from nipa frond. This research used completely randomized design with two factors, i.e. composition factor (inner part particles, outer part particles, mixed particles of inner and outer (50%:50%) ,and three layer particleboard with comparation of outer 25% : inner 50% : outer 25%) and pressing temperature factors (180°C and 200°C). The particle which passed 10 mesh were obtained from Ayah village, Kebumen city, Central Java. The pressing time were 15 minutes with the target density 0.9 g/cm3. The evaluation test referred to JIS A 5908-2003 for its physical properties (density, moisture content, thickness swelling and water absorption) and mechanical properties (modulus of elasticity, modulus of rupture and internal bond strength). The result showed that interaction between composition factor and pressing temperature factor is not significantly affected to properties of particleboard. Composition factor only significantly affected to water absorption properties and highly affected to density, moisture content, thickness swelling, modulus of elasticity, and internal bond of particleboard. Pressing temperature factor only significantly affected to density of particleboard. The best properties of particleboard were obtained from particleboard made from 100% composition of outer part with pressing temperature 180°C. This board had 0.74 g/cm3 density value, 6.08% moisture content, 1.52 % thickness swelling, 61.95 % water absorption, 7.379 kgf/cm2 modulus of elasticity, 23.33 kgf/cm2 modulus of rupture, and 1.74 kgf/cm2 internal bond strength.
