POTENSI EKSTRAK KULIT BUAH JENGKOL (Pithecellobium lobatum Benth.) SEBAGAI TERMITISIDA NABATI PADA KAYU PULAI (Alstonia scholaris L.)
Abstract: Pulai(Alstonia
scholaris L.) wood widely used because it’s easy to obtained and demand is
quite high. Pulai wood included in durable class V and strong class IV-V, so
easily attacked by termite (wood destructive organisms). To prevent and reduce
the impact of termite attack, we can utilize natural materials as basic
materials botanical termiticide. Materials derived from plants are guaranteed
environmentally friendly, because it’s quickly decomposes on ground and does
not harm the non-target. One of the potential is jengkol (Pithecellobium
lobatum Benth.) fruit skin. This research aimed to know about the effectiveness
and potential of jengkol fruit skin extract as botanical termiticide to controlling termite (Coptotermes
curvignathus Holmgren.) attack at pulai wood. This research used Completely
Random Design method wich consists of 4 treatments and 3 replicates with
concentration levels of extract, T0 = 0 g/l of water (0%); T1 = 21 g/l of water
(2%); T2 = 42 g/l of water (4%); T3 = 64 g/l of water (6%). The results showed
that the application jengkol fruit skin extract at the concentration 4% and 6%
is the best treatment to controlling termite, with total mortality amounted to
100%. The value of retention meets National Standards ofIndonesia amounted to
8,58kg/m3 (interior) 4% treatment and 12,35 kg/m3 (exterior) 6% treatment. Both
of it also, able to improve the resilience of pulai wood into class II with
termite consumption levels lower than control treatment. Jengkol fruit skin
extract is effective and has potential as base material botanical termiticide.
