Abstract

Some plastic waste processing into economically valuable recycle products has been done. By using a plastic waste processing machine, a variety of products made from plastic waste can be made, one of which is a paving block that is commonly used as building material. This paving block is called as eco paving block to show the ecology side by using plastic waste as raw material. It has been produced with various compositions and type of plastics, but the optimal composition is not yet known to produce good quality. So, this experiments were carried out using the factorial design as one of the Design of Experiment (DOE) methods to determine the effect of type of plastics and compositions ratio to the eco paving block compressive strength and also it can be obtained optimal composition of the eco paving block. The result showed that the ratio of compositon is 2:3 of sand and plastic can produce optimum eco paving block based on compressive strength. This paving block has an average compressive strength 9.91 MPa. It can be classified into D quality classification that can be used for yards, parks, and others.
