| dc.description.abstract | FEBRINA HERYANI TARIGAN. Wood Acetylation Of Aleurites moluccana,
Durio zibethinus, And Garcinia mangostana woods. Supervised by Luthfi
Hakim and Rudi Hartono.
The alternative that was used to solve the problem of the unstable
dimensions of wood fruits and the susceptible of the wood from termines attack is
an attempt preservation of wood by chemical modification of wood acetylation.
The purpose of this research are to evaluate the stability dimension and the
quantity of the preservatives that absorbed into the Aleurites moluccana, Durio zibethinus, and Garcinia mangostana woods, and to know the durability of wood from termite attack by acetylation with laboratory tests and grave test.
This research carried out by soaking the kemiri wood, durian wood, and
manggis wood for 2 weeks with the concentration of acetic acid solution 10%,
15%, 20%, and 25%. The results showed that concentration of 15% has good stability dimension 67.8% and in addition 44.41%. The greatest retention from the concentration 25% by 7.73 gr/cm3 this his means that the greater the concentration of acetic acid solution, effect to the higher retention becomes which means resistance and the wood becomes better | en_US |
