[en] This study investigated the effect of mixed material composition of jabon (Anthocephalus cadamba Miq.) and andong (Giganthochloa pseudoarundinaceae Steud.) particleboards on their resistance to subterranean termite (Coptotermes curvignatus Holmgren). Six types of 35cm × 35cm × 1.2 cm particleboards were produced and glued with phenol formaldehyde in the proportion of 100:0, 70:0, 60:40, 50:50, 40:60 and 30:70 for jabon and andong. Those panels were tested according to SNI 727-2014. The results showed that material composition of jabon and andong was significantly influenced weight loss and termite mortality. Particleboard with 30:70 jabon-andong proportions had the lowest weight loss (4.28%) and classified as resistant class. Termite mortality rate escalated as jabon composition in the panel decreased.

[en] Andong bamboo (Gigantochloa pseudoarundinacea) is one of the most important bamboo species widely planted in West Java, Indonesia, and play a prominent role in the rural economy. The bottom and the middle parts of Andong bamboo culms are suitable for laminated bamboo lumber raw material. To improve the efficiency of bamboo utilization, the upper part of Andong bamboo culms were use as raw material for strandboard production. The objective of the study was to determine the effect of strand length and specific pressure on the properties of bamboo strandboard. Laboratory scale of bamboo strandboards were fabricated using three different strand lengths (75, 100, and 150 mm), two different specific pressures applied (25 kg/cm² and 30 kg/cm²) and glued with phenol formaldehyde with the targeted density of 0.75 g/cm³. Some physical and mechanical properties of bamboo strandboards were determined. Results showed that the average physical properties of bamboo srandboards were 9.3% (moisture content), 0.76 g/cm³ (density), 3.1% (thickness swelling), 1.6% (wide expansion), and 25.1% (water absorpsion). The average mechanical properties of bamboo srandboards were 760.5 kgf/cm² (MOR), 92.3 10³kgf/cm² (MOE), 5.6 kgf/cm² (IB), and 56.5 kgf (screw holding power). Some physical and mechanical properties of bamboo strandboard were significantly affected by strand length and specific pressure. (paper)
