dc.description.abstract | Oil palm empty fruit bunches (TKKS) are waste from palm oil mill utilization is
still limited. Lignin utilization of oil palm empty fruit bunhes made of natural
adhesive manufacture. Making adhesive is carried out in several stages namely the
manufacture of powder oil palm empty fruit bunches free extractives, lignin
isolation, the manufacture of sodium lignosulfonate, sodium purification
lignosulfonate and the manufacture of adhesive.making the lignin resorcinol
formaldehide adhesive is done by differences sodium lignosulfonate : resorcinol :
formaldehyde mole ratio are ratio 1:1:1, ratio 1:1:2 and ratio 1:1:3. Analysis
perrformed on this adhesive is a test appearance, pH/acidity, density and viscosity
at room temperature and gelatinization time at 100 0C as well the rest levels of
evaporation at 105 0C. The results obtained from testing the appearance of the
adhesive has a blackish brown color. pH of each ratio is ratio 1:1:1 11,2, ratio
1:1:2 11,4 and ratio 1:1:3 12,0. Adhesive Densities are ration 1:1:1 1,2857, ratio
1:1:2 1,2119, and ratio 1:1:3 1,3097. Viscosities are ratio 1:1:1 108,83 cps, ratio
1:1:2 94,31 cps and ratio 1:1:3 129,92 cps. Adhesive gelatinization time don’t
comport with standard. The rest of the evaporation are ratio 1:1:1 50,77%, ratio
1:1:2 42,35% and ratio 1:1:3 41,01%. Of thr treatment was compared with
standard phenol formaldehyde which is SNI 06-4567-1998 liquid phenol
formaldehyde. | en_US |
