ABSTRACT: For optimum
utilization of coconut wood, there are necessity to improve the quality of the
wood caused by higroscopicity, low dimensional
stability, and extreme
variability of dimension
in lateral direction.
The purpose of the
research were to
analyze the characteristics of
coconut wood that
had been treated
by heating and densification. The treatment consist of one or two hours
heating, one hour heating combined to
10 or 20%
densification, two hours
heating combined to 10 or
20% densification. Temperature
that applied for all specimen were 180 oC. The research results are as
follows: (1) Heating treatment combined to densification effective to reduce higroscopicity of coconut wood, (2)
Heating treatment for two hours are suffice
as pretreatment to
densify the soft
part of coconut
wood for 20%,
(3) Dimensional stability
of coconut wood may
improve using heating
combined to densification
treatments that indicated
by decreasing rate of
dimensional change, (4)
Heating and densification
treatment effective to
improve the hardness of soft part
coconut wood.
