【 摘 要 】

Generally, the problem of wood industry in Indonesia is about wood supply for its raw material. Utilization of non-wood materials is alternative solution. Bamboo and corn stalk for example of non-wood lignocellulosic materials had a good potention to develop as biocomposite materials especially for particleboard. The objective of this research was to evaluate of physical, mechanical and durability properties of sandwich particleboard (SPB) made from bamboo Belangke and corn stalk bagasse bonded with isocyanat resin in various level. Board was produced in size of 25 by 25 cm2 with density and thickness target of 0.70 g/cm3 and 1 cm respectively. Bamboo was place for surface layer and corn stalk bagasse as core layer with composition ratio of 1:2:1. Various level of Isocyanat resin consited of 4, 6, 8, and 10% used as binder in SPB manufacruring. Hot pressing temperature and time were set on 160?C and 5 minutes with pressure of 30 kg/cm2. Durability testing of SPB with graved yard test method and sample weight loss was calculated to determine of durability class. The results showed that the physical and mechanical properties generally had fulfilled the JIS A5908-2003 except of internal bond parameter. According to economical reason, board bonded with 4% Isocyanat was recommended as a better product. The durability test showed that weight lost value of board ranged of 8.48 to 10.33 %. Sandwich particleboard was produce in this research classified into durability class moderate to not durable.
