PENGEMBANGAN FUMIGASI AMONIA SEBAGAI METODE FINISHING DAN PENGAWETAN
ABSTRACT: Enhancement of
surface appearance of wood products in wood working industry has been done by
application of wood stain. However, the
use of wood stains has been recently limited due to emission of a hazardous
material. Through this work a new
technique of ammonia fuming has been experimented. The purpose of the research work was to
investigate the effect of ammonia fuming and wood characteristics on the
surface appearance of nangka wood (Artocarpus heteropyllus). The experimental result showed that ammonia
in the volume of 2 liter could change significantly the natural color of (16 x
8 x 2) cm size nangka wood after 24 hours of fuming. Increasing in the period of fuming to 48
hours did not provide any difference in color compared to the 24 hours of
fuming, however the 48 hours fuming generated deeper changes in color on the
surfaces of the wood. Heartwood of nangka
was observed to generate more significant changes in color compared to the
sapwood. Fresh wood produced a darker
color than air-dried wood. The wood
treated by ammonia fuming showed an increase in resistance against termite and
decayed fungi attacks.
