KUALITAS KAYU PULAI (ALSTONIA SCHOLARIS) TERDENSIFIKASI (SIFAT FISIS, MEKANIS DAN KEAWETAN)
ABSTRACT: Pulai (Alstonia
scholaris) was classification as IV-V
for strenght class and V for durability class. This means that pulai has a low
quality. One effort to improved the quality of pulai wood was densification
process. This research aimed to evaluation the physical, mechanical and
durability of pulai wood before and after densification process and to
evaluated the temperature and pressing time on resulted the best quality of
pulai wood. Densification was conducted on 160 °C and 180 °C with three pressing time 40 minute, 50
minute and 60 minute respectively. Densification targetted was 30%. Physical
and mechanical process was conducted based on
British Standard Methods No. 373 (1957), meanwhile durability test
against subterranean termites was conducted with modified wood block test
methods. Result of the research showed that densified pulai wood has the highest quality on physical,
mechanical and durability properties than pulai wood control. The best
densified treatment was on 180 °C with pressing time 60 minute. Densification
process has improve the quality of pulai wood on one level class.
