Abstract

The research aimed to determine drying characteristics, developing drying schedule, and its relationship to the axial position of the sample on the stem, board thickness, specific gravity, and percentage of heartwood. This research used cemara gunung (Casuarina junghuhniana Miq.) as samples with 6 replications and 2 factors that are the axial location (bottom, middle, and top) and board thickness (2 cm, 3 cm, and 4 cm). The drying schedule development followed the Terazawa Method, in which the samples were dried within a temperature of 100°C for 72 h. The proper schedule was then applied and evaluated. The research obtained 11 variations of the drying schedule. The chi-square analysis results indicated that the board thickness and percentage of heartwood were significantly correlated with the development of the drying schedule. The drying schedule using board thickness of 2 cm, 3 cm, and 4 cm can be dried with an initial temperature of 60°C, 50°C, and 47°C, respectively. The wet-bulb depression was 4°C, 2°C, and 2°C, respectively, and the final temperature was 90°C, 80°C,and 65°C, respectively.
