PERUBAHAN KIMIA KAYU PADA GUBAL GAHARU (AQUILARIA MALACCENSIS LAMK.) HASIL REKAYASA
ABSTRACT: Indonesia is the
biggest producer gaharu (A. malaccensis Lamk.) in the world with the best
quality. Agarwood is elite commodity non timber forest products that have
potential as an industrial raw material The research objective is measuring
physical properties (water content and density) of wood tissue is induced to
form the agarwood. Measuring changes in the chemical content (hemicellulose,
cellulose, alpha cellulose and lignin) of wood tissue induced 12 months, 6
months, and the control of long induced agarwood. Treatment in research was
induced period of 6 months, 12 months and control. The analysis was done
according to ASTM Standard D 4933-99 and
TAPPI. The result of research showed that the induced agarwood for 12 months
had a higher density than the control, and 6 months. while the water content
was not significanctly different. The extractive substances that contained in
induced agarwood had a higher value than the control (the value of agarwood
solubility in cold water, solubility in hot water, solubility in NaOH,
solubility in alcohol and benzene). The content of hemicelluloses, cellulose
and alpha cellulose in the induced agarwood
for 12 months trend to be lower than the control.
