Abstract
Recently, potential plastic garbage and sawdust
increasing fastly. Disposal of
plastic waste and
sawdust in large numbers at random are very disturbing
quality of the environment. Various
attempts were made to utilize waste plastic waste and
sawdust, one of which is the manufacture of plastic
composites. The study aims to determine the optimal combination between the composition of plastic waste materials and sawdust kind
Polyethylene sengon by using adhesive urea
formaldehyde (UF) which can produce
optimal quality composite
board. The research design used is a
factorial experiment with three (3) replicates arranged in a completely randomized
design or a Completely Randomized Design (CRD), which consists of two factors,
namely the composition of plastic waste materials and sawdust sengon (10%: 90%
and 30 %: 70%), and the factor levels of gluten (7% and 8%) of the weight of
air-dried material, with analyzed using SPSS. Parameters measured were moisture
content, density and firmness press parallel to the surface. The results showed
the composition of the material and content of the adhesive significantly
affect the density and firmness press, while the water content only on the
composition of the material. The average value of the water content of 6.461 to
9.977%, a density from 0.412 to 0.573 g / cm3, and firmness press parallel to
the surface of 18.652 to 28.520 kg / cm2, in accordance with the standards
dipersyaratkan.Limbah sengon plastic and sawdust can be used as a raw material
composite board , the composition of materials that produce optimal products in
this study using the composition of the waste material and plastic sawdust sengon
70%: 30%.
Keywords: Waste plastic,
