STABILITAS DIMENSI KAYU KARET (Hevea brasiliensis, Muell. Arg) BERDASARKAN POSISI KETINGGIAN PADA BATANG DAN SUHU PENGERINGAN
Abstract: This research was
carried out in the Wood Workshop Faculty of forestry University ofTanjungpura
to manufacture test and example in the lab Silvikultur for testing the
stability of dimension lumber, Wood is a material that besifat hygroscopic
materials that can absorb and remove water depending on the environment. The
test sample is inserted into each of the oven with a temperature of 50 0 C, 70
0 C, and 90 0 C until it weighs the constant. The purpose of this research is
to know the influence of the position on the stem height and temperature of
drying as well as the interaction of these two factors the dimension stability
of wood against the Rubber as well as knowing the position on the stem height
and the most appropriate drying temperature so that it can show the highest
dimensional stability. The results of the research on the radial direction
indicates that the value of moisture content ranged from 9.8394%-10.3484%
increase of the drying temperature decreases. While the value of density showed
no noticeable difference i.e. ranged from 0.8188%-0.7669%. Depreciation value
dimensions vary greatly on the position of the height of the stem that is ranged
from 1.2189%.-3.1405%. Research on tangential direction indicates that the
value of moisture content ranged from 9.9894%-14.6225% increase of the drying
temperature decreases. While the value of density showed no noticeable
difference i.e. value 0.7390%-0.8143%. Value changes in dimensions ranging from
1.1594%-2.1629%. The value of depreciation is not too mean and very varied
temperature drying.
