EFEKTIVITAS BAHAN PENGAWET ALAMI DARI TANAMAN TEMBELEKAN (Lantana camara L) PADA BEBERAPA JENIS KAYU TERHADAP SERANGAN RAYAP TANAH (Coptotermes sp.)
Abstract: Many favorable
properties of wood are available in almost all parts of the world, easily
obtained in different shapes and sizes, relatively easy to process, as well as
very decorative appearance. However, wood also has a weakness that could be
damaged by a variety of factors either biological, physical, mechanical or
chemical. In reality, the main factors causing damage to the wood are fungi,
bacteria, insects and marine animals (marine borer). The organisms might damage
the wood because they make as a shelter or as feed. Therefore, there should be
conducted wood preservation to overcome the unfavorable properties of the
woods. Wood preservation aims to extend the use of low-class durability of
timber species such as Bayur (Pterospermum sp), Durian (Durio zibethinus) and
Benuang (Octomeles sumatrana Miq). This study aimed at determining the
effectiveness of a natural preservative tembelekan (Lantana camara L). The
research was conducted at the Forestry Sciences Laboratory, Department of
Forestry, Forestry Faculty, Tadulako University and Talise Mantikulore Sub-district,
started from May to July 2013. The study was designed with the method of
completely randomized design (CRD) with three wood species treatment, namely
bayur, durian and benuang. Each was preserved with a natural preservatives of
tembelekan extract with a concentraation of 13,04%. There were 10 samples of
each type of wood, consisting of 5 test samples preserved and 5 controls
(without preserrvatives). There were 30 test samples. The parameters observed
were preservative effectiveness of the sample weight after feeding on soil
termites. The study shows that highest natural preservative effectiveness on
benuang wood was preserved with the sample weight loss of 2,25% and the lowest
on bayur wood was preserved with the sample weight loss of 3,47% when they were
compared with the control sample (without preservative). Using tembelekan
extract might increase wood resistance to soil termite attacks.
