DISTRIBUSI KOMPONEN KIMIA KAYU MAHANG (Macaranga hosei King)
Abstract: This research aim
was to know the chemical distribution of wood (Macaranga hosei King) based on
its stem height/axial direction (base, middle and end of stem) and the depth of
stem/radial direction (2/3 3/3 rays, 1/3 2/3 rays and 0 1/3 rays). The
experimental includes the percentage of alcohol benzene-soluble extractive
content, lignin content, holocellulose and ?- cellulose. The result showed base
on stem height that the percentage of alcohol benzene soluble extractive,
lignin, holocellulose and ?- cellulose content decrease from the base, middle
and to the end of stem. Base on depth of stem, the result showed that the
percentage of alkohol benzena-soluble extractive content, lignin content,
holocellulose and ?- cellulose decreasing from 2/3 3/3 rays, 1/3 2/3 rays and
to the part of 0 1/3 rays. The interaction of stem height and depth of stem has
significantly affected to the percentage of alcohol benzene-soluble extractive
content. The overall result showed that Mahang wood is suitable for used as
sawn timbers, wood panels and raw materials for pulp and paper.
