FABRICATION AND CHARACTERIZATION OF COMPOSITE FROM CASSAVA STEMS AND SUGARCANE BAGASSE FIBERS AS PARTICLEBOARD MATERIAL

Abstract

 

Composite particle boards mixed with cassava stems and bagasse has been successfully fabricated. The purpose of this study was to find out the effect of cassava stem powder and bagasse fiber powder can be used to produce particle board, the effect of plastic waste as particle board adhesive, particle boards from cassava stem powder waste and bagasse fiber powder can meet SNI standards. Composition particle of 70:30, 60:40, 50:50, 40:60, 30:70, with variations of plastic adhesive 10%, 15%, 25%. The characterization results of physical properties and mechanical properties of the most optimal particleboard produced at 70:30, 60:40, 50:50 with 25% plastic adhesive variation composition has a density value of 0.44 𝑔/𝑐𝑚³, 0.43 𝑔/𝑐𝑚³, 0.40 𝑔/𝑐𝑚³, 0.36 g/cm³ and 0.36 g/cm³. The moisture content values are 4.44%, 4.44%, 6.52%, 4.76% and 4.65%. The water absorption values were 72.72%, 109.09%, 115.38%, 125% and 154.54%. Flexural strength values (MOE) of 699.87 kgf/cm², 646.77 kgf/cm², 667.25 kgf/cm², 576.65 kgf/cm² and 615.51 kgf/cm². The fracture toughness values (MOR) were 232.23 kgf/cm², 218.07 kgf/cm², 186.55 kgf/cm², 155.95 kgf/cm² and 199.03 kgf/cm². The obtained values of density, moisture content, and fracture toughness have met SNI standards, while water absorption and flexural toughness have not met SNI standards.
