ASETILASI KAYU KEMIRI (ALEURITES MOLUCCANA), DURIAN (DURIO ZIBETHINUS), DAN MANGGIS (GARCINIA MANGOSTANA)
ABSTRACT: The problem solve of
unstable dimensions wood fruits and susceptible wood from termites attack was
an attempt preservation of wood by acetylation. The research purposes were to
knew the effect of wood variety and acetic acid concentration to retention
value, to evaluated the Weight Percent Gain (WPG) and dimention stability, and
to evaluated durability from attack termite based on laboratory dan grave yard
test.
Some kind of wood such as kemiri, durian, and manggis woods were treated
by soaking during 2 weeks with acetic acid concentration of 10%, 15%, 20%, and
25%. The results showed that high retention on kemiri wood with concentration
of 25% was 7.73 gr/cm3. Durian wood in concentration of 15% had WPG value
(44.41%) was good dimention stability (67.8%). The increasing of acetic acid
concentration caused the increasing of retention and wood resistance from
termite attack in laboratory and grave yard test.
Key words: acetic acid, wood
