Abstract

Lignocellulosic waste from oil palm industry is a potential versatile resource. It can be used as raw material of bio-composite, pulp and paper, bioenergy, and many chemicals products.  The aimed of this research was to investigate the characteristics of particleboard from oil palm empty fruit bunch (EFB) bonded with phenol formaldehyde (PF)-fortified oil palm EFB liquid adhesive.  Fortification level of EFB liquid was varied at 5, 10, and 15%. The adhesive level of 10, 15, and 20% were used for particleboard manufactures with target density of 0.7 g cm-3. The particleboard quality was evaluated based on its physical (density, moisture content, thickness swelling) and mechanical properties (modulus of elasticity, modulus of rupture, internal bonding, and screw holding resistant) according to JIS standard. In order to improve bonding quality, the EFB particles was treated by hot water at 100 oC for 6 h.  The results showed that the quality of particleboard increased by addition of fortifier as well as adhesive level, except for thickness swelling. The best particleboard properties was produced with 20% adhesive level and 15% fortifier, however, physical and mechanical properties of most particleboard produced did not satisfy the JIS A 5908:2003 requirement.Keywords: empty fruit bunch, fortifier, liquid adhesive, oil palm, particleboard, phenol formaldehyde

Abstract

Lignin is one of the major component of bamboo, together with cellulose and hemicellulose, which may differ comparing to wood lignin. Lignin characteristics of four bamboos species, i.e.  betung (Dendrocalamus asper), ampel (Bambusa vulgaris), andong (Gigantochloa nigrociliata), and tali (Gigantochloa apus) were investigated. As lignin characteristics;  lignin content and proportion of lignin monomer were investigated by Klason method, UV spectrophotometry, and Pyrolysis Gas-Chromatography analysis, respectively. Lignin content of bamboos varies depending on species and position of sample. Bamboo lignin was categorized into syringyl-guaiacil-p-hydroxyohenil (S-G-H) lignin. There was high correlation between proportion of syringyl unit with acid-soluble lignin obtained during Klason lignin procedure.
