The Properties of Particleboard Composites Made from Pleurotus ostreatus Baglog Waste Using Citric Acid and Sucrose Adhesive

Pleurotus ostreatus (PO) is one of the edible mushrooms cultivated in baglog as medium. Baglog’s productive age around 4-5 weeks. The more PO produced, amount waste also increases. main component wood sawdust, which contains lignocellulose; therefore, has great potential to be used a raw material for making particleboard. This research aims make particleboard from and determine effect type adhesive concentration on physical mechanical properties that produced. Particleboard made by mixing waste, whose particle size 40 mesh, with citric acid sucrose adhesives concentrations are varied between 50%, 60%, 70%. Furthermore, was formed using hot press machine (200 °C, 10 MPa) 15 minutes. obtained will analyzed its properties, including density, moisture content, water absorption, thickness swelling, morphology, modulus rupture (MOR) elasticity (MOE). test refers JIS A 5908-2003 8 standard. As result, (citric 70%; C70) better compared adhesive, density value 0.86 g/cm³, content 4.118%, expansion 3.992%, absorption capacity 36.89%, 13.456%, MOR 9.682 MPa, MOE 1.455 GPa.
