RETENSI BAHAN PENGAWET EKSTRAK DAUN TEMBELEKAN (Lantana camara L) PADA BEBERAPA JENIS KAYU DAN EFEKTIFITASNYA TERHADAP SERANGAN RAYAP TANAH (Coptotermes sp.)
Abstract: High-grade
durable wood could not be longer to meet the various needs, this caused by
limited and the more expensive price, so it must use low grade durable wood.
The use of low grade durable wood should be followed by the wood preservation
process. This study aims to determine the preservative retention of leaves
tembelekan (Lantana camara L) on bayur (Pterospermum sp), benuang (Octomeles
sumatrana Miq) and durian (Durio zibethinzs) and its effectiveness against
subterranean termites (Coptotermes sp), attack. It was conducted at the
Laboratory of Agrotechnology, Faculty of Agriculture, University Tadulako in
March to june 2014. Testing Subterranean termites (Coptotermes sp) test was
carried out at the Maku Village, District of Dolo, Sigi Regency, Central
Sulawesi, using a completely randomized design (CRD), with treatment of
different wood species and 3 days soaking duration at a concentration of 1%
preservative with 6 replications. The results show the moisture content of
bayur, benuang and durian woods are 13,10%, 10,81% and 11,35% respectively. The
wood densiy of bayur 0,480g/cm3, benuang 0,277 g/cm3 and durian 0,402g/cm3 and
the highest retention values is found at wood of durian 59,09 g/cm3 and the
highest retention values is at bayur 41,67 g/cm3. In addition, the highest
weeight loss (leas effectiveness) of 15,02% on the wood of bayur (control) and
the lowest (highest Effectiveness) on wood of benuang 0,72%.
