Pengendalian Rayap Tanah Coptotermes curvignathus Holmgren Menggunakan Ekstrak Daun Gulma Sembung Rambat (Mikania micrantha Kunth)

Abstract: Mile-a-minute weeds (Mikania micrantha Kunth) contain secondary metabolite compounds such as tannins, alkaloids, saponins, steroids and terpenoids that can be used as insecticides. Those compounds can be used to  regulate  subterranean  termites  Coptotermes  curvignathus  Holmgren.  This  study  aims  to  find  Lethal Concentration (LC)50 extract of M. micrantha on C. curvignathus and extract concentration of M. micrantha which caused least weight loss percentage of paper disc. The research was conducted in 3 months at the laboratory  of  Biotechnology  in  Faculty  of  Mathematics  and  Science  of  Tanjungpura  University  and laboratory of Forest Product Technology in Faculty of Forestry of Tanjungpura University. Extract of  M. micrantha  was  obtained  through  maseration  method  using  methanol.  The  no-choice  bioassay  test  was carried-out by treating paper discs with extracts at the concentration of 6%, 8%, 10% w/v (g/ml), DMSO 10%  as  control  solvent  and  termiticide  (has  active  compounds  fipronil  50  g/l)  was  made  at  the concentration of 5% v/v (ml/ml) as positive control. LC50  determined by probit analysis. The bioassay test showed  that  LC50  extract  of  M.  micrantha  has  an  effect  to  C.  curvignathus  in  8,07%,  and  caused  least weight loss percentage of paper disc (27,26%) in 10%.
Key words: Mikania micrantha, subterranean termite, mortality, weeds
