EVALUASI ASAP CAIR SEBAGAI BIO-TERMITISIDA UNTUK PENGENDALIAN RAYAP TANAH Coptotermes sp.
ABSTRACT: Coptotermes sp. is
the most important genus of termites in buildings and plantations. In recent
years, methods to combat termite infestation by using chemicals have caused
serious hazards to humans and environment. The utilization of liquid smoke as
the bio-termiticide to combat termite infestation is one of the appropriate and
interesting technologies to develop. The aims of this research are: (1) to
produce liquid smoke made from waste of empty fruit branch of oil palm by
applying a condensation process, (2) to determine the optimum temperature of
the production of liquid smoke, (3) to identify the component of liquid smoke, (4)
to evaluate the bio-activity of liquid smoke as bio-termiticide on termites in
the laboratorium.
Liquid smoke was produced under various temperatures 350, 400, 450 ยบ C
for 90 minutes. Phenol and acid analysis the components of liquid smoke were
qualitatively analysed by using a gas chromatography mass spectrometer/GCMS.
Evaluation of liquid smoke on subterranean termite was done according to Ohmura
(1997) procedure under various concentration of 1%, 2%, 3%, dan 4%.
Identification of the component of liquid smoke showed that mostly
phenols and acetic acids were present in all temperature of pyrolisis. Content
of phenols and acids were increasing with higher temperatures. The highest
mortality of termite after 3 (three) weeks observation was recorded using
liquid smoke produced at a temperature of 450 ยบC, followed by 400ยบC, 350ยบC and
the control, respectively. The highest weight loss of the paper disc was observed
with the control with a weight loss of 100%, followed by 350ยบC, 400ยบC, dan
450ยบC, respectively.
