PENGARUH DIAMETER LOG DAN LAMA PEREBUSAN TERHADAP PRODUKTIVITAS DAN RENDEMEN FINIR KAYU SUNGKAI DALAM KEGIATAN PENYAYATAN FINIR (SLICING) DI PT. DAYA SAKTI UNGGUL CORPORATION
Abstract: 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 3 x
3 factorial design. The diameter classes of sungkai were 20-25 cm, 26-30 cm,
31-35 cm. If analysis of variance 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 also
affected by the diameter and the steaming duration. The wider the log diameter
was, the higher the recovery was. A wide log produced more veneer than a narrow
log. 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 (24 h), B2 (30 h), and B3 (36 h) were 0.0287 m3/h,
0.0288 m3/h, and 0.0313 m3/h respectively. The sungkai final recovery of A1
(20-25 cm) was 7.62%, A2 (26-30 cm) was 8.15%, and A3 (31-35 cm) was 8,49%.
That of B1 (24 h) was 7.35%, B2 (30 h) was 8.26% and B3 (36 h) was 8.64%.
plywood samples used for A1 were 9 sheets (B1 = 24 hours), 10 sheets (B2 = 30
h), for A2 were 14 sheets (B1), 16 sheets (B2), and 17 sheets (B3), and for A3
were 20 sheets (B1), 23 sheets (B2), and 24 sheets (B3).
Key word: Log diameter and
