Abstract

This research has been done by testing the adhesive firmness of resorcinol formaldehyde from Johar sawdust extract. This study aims to determine the best adhesive characteristic made of the mixture of Johar sawdust extract with resorcinol and copolymerized with formaldehyde. The composition comparison of tannin extract, resorcinol, and formaldehyde extracts are 3: 1.4: 1; 3: 1,6: 1; 3: 1.8: 1, and 3: 2.0: 1 gram. The adhesive firmness test, physical test and chemical test of for lamina wood aims to determine the quality of the adhesive result. Based on the test result of adhesive firmness of lamina wood was obtained the best value from composition ratio of 3:1,6:2 is equal to 115,37 kg / cm2, which has the physical characteristics of brownish red liquid, phenol typical odor, has a viscosity of 2.82 poise , mass type equal to 1.176 g / mL, pH equal to 11.02, solid resin content equal to 43.08% and formaldehyde emission levels equal to 0.295 mg/L. The value of adhesive firmness which obtained is appropriate with SNI (1998) SNI (1998) and JAS standard (1996).
