Preserving  rubber  wood (Hevea brasiliensis)  can avoid quality decrease  that caused  by termite and fungi. For preserving  rubber  wood  we can use "Blue Vitriol (Terusi)" with sulphur copper as active material.  This research used 3% and 5%  concentration  of Blue Vitriol, while for preserving  we use a simple and pressure   method.    The  simple   method   contained   dyeing,   varnish,   and submersion  of rubber wood in preserving.  It pressure.method  used empty cell and complete  cell method,  with 3 time variable of pressure,  they were 0.5, 1, and 2 hours.The result of this research, concluded that the most effective simple method of preserving  to avoid the attack of fungi and termite was  submersion  for 1 hour and  5%  concentrate  of preservative   material.  While  when  using  pressure method   the  effective   way  was using  0.5  hour  and  3  % concentrate   of preservative  material.
