Abstract

The use of 100% palm oil polyol without the addition of a chain extender produced foam which initially expands and then collapses so that the resulting foam has tight pores, dense texture, and brittle (brittle). It was necessary to use a chain extender to improve the flexible properties of the foam. This study aimed to examine the ratio of palm oil polyols with a chain extender to produce flexible polyurethane foam with good characteristics. The treatment of this study was a combination of types and comparisons of palm oil polyols with chain extenders which were carried out 3 times, consisting of factor A = type of chain extender (diethylene glycol (DEG), diethanolamine (DEA), and polyethylene glycol (PEG)-400) and factor B = ratio of palm oil polyols. with a chain extender (80%:20%; 70%:30%; 60%:40%; 50%:50%). The obtained foam was observed visually, foam development, and foam density. The best sample for each type of extender was analyzed by FTIR. The results showed that 40% PEG-400 has succeeded in producing flexible polyurethane foam with higher expansion (291.22%), lower density (29 kg/m3), and visually has the best flexible properties. Based on FTIR analysis, the use of PEG-400 in the polyol system can increase the reactivity of palm oil polyols to isocyanates.

Abstract

Bioplastics are one of the alternatives to replace synthetic plastics. Bioplastics are plastics made from natural materials readily decomposed by microorganisms so that they are environmentally friendly. Oil Palm Empty Fruit Bunches (OPEFB) have cellulose content that can be utilized as raw material in the manufacture of bioplastics. This research aims to determine the best formulation of OPEFB cellulose-based bioplastics as environmentally friendly packaging. The method used in this research is the Response Surface Methodology (RSM) optimization method in the Mixture (Optimal Custom Design) section found in the Design Expert version 13 application. The factors analyzed in making bioplastics are glycerol, starch, CMC, and chitosan. Bioplastic observations include tensile strength, elongation, elasticity, thickness, water resistance, and biodegradation. The result of OPEFB cellulose obtained in this study is 71.88%, where the cellulose produces strong bioplastic properties. The optimum solution of bioplastic formulation produced is the addition of glycerol of 0.89 g, starch of 2.99 g, CMC of 2.11 g, and chitosan of 3 g Laboratory verification responses produced are tensile strength of 12 MPa, elongation of 31.34%, elasticity of 890.67 MPa, thickness of 0.25 mm, water resistance of 88.95%, and biodegradation of 4.34%/day.
