PENGARUH KONSENTRASI DAN LAMA PERENDAMAN KAYU SENGON (Paraserianthes falcataria L. Nielsen) DALAM EKSTRAK DAUN SIRSAK (Annona muricata L.) TERHADAP SERANGAN RAYAP TANAH (Coptotermes sp.)
Abstract: Wood has many
contribution for life. It can be useful for bueldings, huose ware, and for
other using. The use of wood are followed by huma needs for manufactured wood
in creasingly, while long life wood tend to be more scarce and higher in price.
This research aims to know the influence of the concentration and the immersion
time for sengon wood treated in extracted soursop leaf to defence from
subterranean termite. This research was conducted in both forestry
Laboratorium, Departement and faculty of forestry, University of Tadulako and in
rural of Baiya, Distict of Tawaely. Starting from Desember 2013 till Februari
2014. This research used a complete randomized factorial design. The first
factor was the concentration of extracted soursop leaf (A) was 4.76% (A1),
13.04% (A2) and 16.66% (A3). The second factor was the immersion time for
sengon wood treated in extracted soursop leaf (B) was 5 days (B1), 10 days
(B2), and 15 days (B3). The results show that the highest of losing weight is
in the control (A0B1) with 3.3%, and the lowest of losing weight is in the
concentration of 150g with 10 days immersion (A1B2) with 1.21%. The
concentration of extracted soursop leaf and the immertion time of sengon wood
did not significantly influence to the lose of weight in tested sample.
