Wood has been widely used as raw material for making products needed by human, such as building, furniture, interior and exterior products. Indonesia has more than 4000 species of woods, but 80% of the woods are categorized as low-durability class, so for these types of wood require preservation to extend its life service. Since chemical preservation methods are not environmentally friendly, a natural method was used in this study. Research on preservation of Ketapang wood (Terminalia catappa) using Sambiloto (Andrographis paniculata) leaf extract for the manufacture of home interior products has been carried out. Ketapang wood was preserved by hot bath at temperature of ± 80oC using Sambiloto leaf extract with variation of concentration of 10%, 12.5% and 16.67% for immersion time of 1 hour, 2 hours and 3 hours. The retention value of each variation was calculated and compared with the preservative value for the interior product of SNI 03.5010-1.1999 (≥ 8 kg/m3). The result of the study has been in accordance with SNI, which is 9,6 kg/m3, obtained at the concentration of preservative 12.5% for 3 hours immersion time.
