By Sasa Abdurrohim and Didik Achmad Sudika

Abstract

Most of the Indonesian wood species exhibit a wide differences in treatability. This may reduce effectiveness in loading several wood species simultaneously. This study investigated treatability of 41   wood  species   through  full-cell   process   using  CCB  (copper-chrome-boron)  preservatives. Representative wood samples, measuring 5 cm wide, 5 cm thick and I 00 cm long were preparedfrom each species and then remain to reach the air-dry condition.  Pressures imposed during the process were consisted of initial and final vacuum al 500 mm Hg for  15 minutes, and a hydraulicpressure of 10 atmospheresfor 60 minutes. The results revealed that 20 of the study species were classified easy, I 2 species were moderate, 5 species were difficult, and the remaining 4 species were very difficult.  Wood species within the class could be treated simultaneously. Results also indicated that there were great variations of chemical retention within the same class of penetration
