UJI RETENSI DAN EFEKTIVITAS TANAMAN KUMIS KUCING (Orthosiphon aristatus) TERHADAP SERANGAN RAYAP TANAH (Coptotermes sp) PADA KAYU DURIAN (Durio zibethinus)
Abstract: Nowadays,
utilization ofnon-durable wood species in Indonesia is one alternative to meet
the needs ofthe wood. Use
natural preservatives such
as Orthosiphon aristatus
in natural wood
preservation processis
highly recommended as
environmentally friendly.This study
was aimed to
determine retention and the effects of Orthosiphon aristatus leaves
extracts as preservation material of Durio zibethinus wood on the Coptotermes
sp. Attacks. Regency and the laboratory of Forestry Science, Tadulako University, from May to June 2013.
The study was using completely randomized design with factorial
pattern. The treatment
of study was
applying two factors.
First, concentration of Orthosiphon aristatus
extracts with three
levels, namely; 9.09%
(A1), 16,67% (A2),
and 23,07% (A3). Second, Dipping
time with three levels,namely: 1 day (B1), 3 days (B2), and 5 days (B3). The results showed
that the highest
retention value (3,538g/cm3)
was achieved by
the combination treatment between
concentration 23,07% and dipping time 5 days (A3B3) while the lowest retention value (0,562g/cm3)
was achieved by
the combination treatment
between concentration 9,09%
and dipping time 1 day (A1B1). Hence, the lowest effectivity of
preservation materials indicated by the highest
weight loss,was achieved
by A1B1 combination
treatment (3,37%) while
the lowest (highest effectivity)
was achieved by (A3B3) combination treatment (1,88%).
