VARIASI LAMA PERENDAMAN DAN KONSENTRASI PHENOL FORMALDEHIDA TERHADAP KUALITAS PAPAN LAMINA DARI BATANG KELAPA SAWIT
ABSTRACT: One way to approve
laminated board quality of palm oil trunk was soaked the laminated board with phenol formaldehyda (PF). The purpose of
this study was to evaluate the influence soaking time variation and concentration
PF than to determine the best treatment in this research. Laminated board was
consisted 3 (three) layers with size 45
cm (length) x 7 cm (width) x 3 cm (thick). The variation of these research were
soaking time (10 minutes, 2 hours, and 24 hours) and PF concentration (5.10.15.
and 20% ). These study used random experimental factorial design and the
results were compared with JAS 243:2003 standard. Results showed weight gain
value, density, moisture content, water absorption 2 hours and 24 hours,
thickness swelling on immersion 2 hours and 24 hours, thickness swelling on
immersion 2 hours and 24 hours around, delamination test, modulus of rupture,
and modulus of elasticity. Result showed that 3.82-15%, 0.39-0.47 g/cm3,
11.66-14.16%, 36.15-46.38%, and 78.87-98.65%, 2.5-11.58% and 5.13-17.58, 0%,
170.23-250.15 kg/cm2, and 17224-43767 kg/cm2. Moisture content and delamination
values have fulfilled JAS 243:2003
standard. The other hand, MOE and MOR values were not fulfilled yet. The best
treatment laminated board made from palm oil trunk was to immerse 10 minutes
consentration 15%.
