ASETILASI KAYU RAMBUTAN (NEPHELIUM LAPPACEUM L), CEMPEDAK (ARTOCARPUS INTEGER MERR), DAN RAMBAI (BACCAUREA MONTLEYANA MUELL. ARG)
ABSTRACT: The utilization of
fruit woods increased according of increasing human needs. Several weakness of
fruit woods were bad dimensional stability and susceptible wood from termite
attack. Preservation can improve the dimensional stability and increase the wood
from termite attack. One preservation method of was acetylation. The research
purpose were to known the effect of rambutan, cempedak and rambai woods variety
and acetic acid concentration to retention value, to evaluated the dimention
stability and Weight Percent Gain and to evaluated durability from attack
termite based on graveyard test and laboratory test.
Some kind of wood such as rambutan, cempedak and rambai woods were
treated by soaking during 2 weeks with acetic acid concentration of 10%, 15%,
20% and 25%. The results showed the effective retention on rambai wood with
concentration of 20% was 3.81%. The high dimention stability ASE on rambutan
wood with concentration of 15% was 73.37%, and the high WPG on rambai wood with
concentration of 25% was 46.66%. The increasing of acetid acid concentration
caused the increasing retention and wood resistance from termite attack in
graveyard test and laboratory test.
Key words: Wood, acetylation,
ASE, WPG, termite
