Physical Properties of Sago Bark

Abstract

This study aim was to determinate physical properties of sago bark. This research was a descriptive research with five repetitions. Physical properties observed included moisture content, acid resistance, alkaline resistance, compressive strength, and modulus of rupture. The results obtained were then compared with JIS A 5908-2003 and SNI 01-0608-89. The results showed that water content of sago bark was 33.74%, resistant against acid and alkaline, compressive strength equal to 64.09 N/mm2, and modulus of rupture 87.29 N/mm2. The water content was not conform to JIS A 5908-2003 and SNI 01-0608-89 standards, but resistance against acids and alkaline corresponded to JIS A 5908-2003. The compressive strength and modulus of rupture were classified in strong classes I and II in SNI 01-0608-89 wooden strength class.
