The aims of research were to determine the effects of log diameter and steaming duration on the productivity and the recovery of sungkai, to determine factors affecting both, and to test the veneer delamination of Sungkai. The research method was the 3x3 factorial design. The diameter classes of sungkai were 20-25Cm, 31-35Cm. If analysis ofvariance test had showed a significant effect at the level of significance of 5% and 1%, test would have been continued with honest significant difference test. The productivity of Sungkai were affected by the diameter and the steaming duration. The wider the diameter was and the longer the steaming duration was, the higher the productivity was obtained, idest for sungkai with steaming duration 36 hours. The recovery of Sungkai were by the diameter and the steaming duration. The wider the log diameter was, the higher the Slimilarly, the longer the steaming for 36 hours, the hardness of log decreased, wood was more elastic, knots and irregular fibres were softer, and the surface of wood was smoother. The sungkai productivity for A1 (20-25 cm), A2 (26-30 cm), and A3 (31-35 cm) were 0.0281 m3/h, 0.0300 m3/h and 0.0307 m3/h respectively. That of B1 (24h), B2 (30h), B3(36h) were 0.0287 m3/h, and 0.0313m3/h respectively. The sungkai final recovery of A1 (20-25cm) was 7.62%, A2 (26-30 cm) was 8.15% and A3 (31-35 cm) was 8.49%. That of B1 (24h) was 7.35%, B2 (30h) was 8.26% and B3 (36h) was 8.64%. Plywood samples used for A1 were 9 sheets (B1=24 hours), 10 sheets (B2 = 30h), for A2 were 14 sheets (B1), 16 sheets (B2), and 24 sheets (B3).
