Drying and Preservation of Kamalaka Wood from South Kalimantan

Drying properties and preservation of kamalaka wood need to be research in order to support efforts to repair and increase the quality of wood. This study aims to under stand the variations of thickness board to drying properties and the influence of concentrationand soaking duration to the retention and penetration of preservative CCB and Boron. Results of this research showed that the dryingrate decrease in moisture content of kamalaka wood every day to thickness board 2. 0 cm, 2.5 cm and 3.0 cm respectively 0.6%, 0.5 5% and 0.4 9%. During drying, the board changed the farm of cupping, broken and split awng the fibers and most severe occurred on board the size of 2. 0 cm. Retention of CCB and Boron varies.from 4.9 kg/ m' to 11.3 kg/ m', while penetration.from 4.6 mm to 7 mm. Concentration highly significant effact to retention of CCB and Boron so significant effact to penetration of CCB. The addition of concentrationon improve retention CCB and Boron as well as increased penetration of CCB. Wbile soakingduration does not significant effact. Wood kamalika can bepreserved with CCB with concentration 10% and soaking duration minimum during 8 days, and if wear Boron with concentration 10% and soaking duration should be more than 8 days.
