Preserving Wood Preserving Jabon Cold Heat Soak.
Supervised by RIDWANTI BATUBARA and Lutfi HAKIM.
The durability of the wood is the durability of a wood species against
destructive factors coming from outside the body of the wood itself. The purpose
of this study was to quantify the value of retention and penetration, dimensional
stability and strength test Jabon after preserved wood preservatives boric acid
(H3BO3) with a heat bath of cold preservation method. Treatment of wood
preservation research Jabon consists of sample size (20 x 5 x 1, 20 x 5 x 5 and 25
x 5 x 5) and reagent (2 g of turmeric extract in 100 ml of alcohol and 20 ml of
HCl is dissolved in 80 ml of alcohol and saturated with salicylic acid) using boric
acid preservative. Testing of mechanical properties and the size of the test sample
based on the standard ASTM D 143 in 2005
The results showed that Wood Jabon retention values ranged from 16.31
kg/m3-25, 31 kg/m3, the penetration value ranging between 13 mm-16.8 mm and
ASE values ranged from 4.82% -13.46%. MOE values ranged between 19415
kg/cm2-20364 kg/cm2, while the MOR values ranged between 829.28 kg/cm2-901,
88 kg/cm2. Concentration differences significantly affect retention and
penetration value, while the value of dimensional stability, MOE and MOR, the
differences do not affect the real concentration. | en_US |
