Penggunaan Tepung Buah Nipah (Nyfa Fruticans Wurmb) sebagai Ekstender pada Perekat Urea Formaldehid untuk Papan Partikel
Abstract: Nipah fruit (Nyfa
Fruticans Wurmb) is a seasonal forest product abundantly produced in each
season. Nipah fruit flour is believed to also function as an extender during
adhesion process of wood products such as plywoods and particle boards. The
study aims to determine the right composition between nipah fruit flour and
industrial flour as an extender which, together with urea formaldehyde
adhesive, to be applied to particle board. Results revealed that the
composition of 50% industrial flour and 50% nipah fruit flour (A3 treatment)
gave the highest Modulus of Elasticity (MoE) with value of 16,833.90 kg/cm2 while
average value of all treatment was 12,131.41 kg/cm2. The MoE of A3 treatment
fulfilled the national standard (SNI) of 15.000 kg/cm2. As for MoE, the
composition of A3 (50% industrial flour and 50% nipah fruit flour) was the most
efficient mixture in producing the highest MoR with 119.30 kg/cm2. The MoR
value for A3 also fulfilled the national standard of 80 kg/cm2. Comparing
between treatments, all other treatment gave the MoE value less than reuired by
national standard. The particle boards produced by other treatments were easily
bent due to high carbohydrate and water content that weaken the elasticity of
boards. For MoR character, all treatments gave value as required by national
standard (higher than 80 kg/cm2) except treatment A5 which gave the value of
less than required (76,36 kg/cm2).
