The Effect of Bamboo Species and Particle Geometry on Physical Properties of Cement Board

Abstract

Non-wood raw materials that are lignocellulosic include bamboo, it mostly found in the tropics area such as Asia, Africa and America. The potential of bamboo in Maluku especially Seram Island is spread among others in Taniwel located in Buria village, and Kairatu sub district, where there are several types of bamboo such as bamboo petung (Dendrocalamus asper), bamboo jawa (Gigatocchloa atter) and bamboo suanggi (Bambussavertillata) can be used as raw material of cement board. The cement board as well as the particle board, the particle shape for the cement board, among others, can be a flake, shaving, strand, splinter, wood wool (excelsior), fiberand wood flour. This study used three species of bamboo as a factor A and particle geometry as factor B with each of them three levels and three replications, where the experimental design used was a completely randomized design. The result of the analysis showed that the particle geometry had a significant effect on the oven dry moisture content and had a height significant effect on air dry density and oven dry density. The data show that the average air dry moisture content rate is 4,544%, oven dry of 8.482%, air dry density of 0.542 g / cm3, oven dry density of 0.547 g / cm3, water absorption of 21.15% and thickness swelling of 25.45 %.
