Alternative raw materials and environmentally friendly adhesives are important for the particleboard industry. The purpose of this experiment is to develop eco-friendly particleboard made of alang-alang (Imperata cylindrica) and sorghum (Sorghum bicolor) bagasse mixture bonded with citric acid-sucrose. A preliminary experiment was conducted using alang-alang and citric acid only to observe effect of resin content, pressing temperature and pressing time on the board properties. The resin contents of citric acid used were 15, 20, 25, and 30% based on dry weight of the particles. The particles were hot pressed at temperature of 160, 180, and 200 °C and pressure of 25 kgf/cm2 for 5, 7, and 10 min. Enhancements of the board properties were attempted. The first enhancement properties was conducted by mixing citric acid with sucrose at ratio of 25:75; 20:80; 15:85; 10:90; 5:95; and 0:100. The second attempt was by mixing alang-alang with sorghum bagasse at ratio of 75:25; 50:50; and 25:75. All the boards were made with target density of 0.8 g/cm3. The Japanese Industrial Standard (JIS) A 5908 was used to evaluate the properties of the boards. The results showed that the alang-alang board properties using 20% citric acid, pressing temperature of 200 °C for 10 min were met the JIS standard for type 8 board. Properties enhancement was achieved at ratio of citric acid and sucrose of 10:90; and ratio of alang-alang and sorghum bagasse of 25:75. It is concluded that alang-alang/sorghum bagasse and citric acid-sucrose are promising materials for preparation of particleboard.
