The ever-increasing problem of plastic waste is an environmental issue that requires innovative and sustainable management. This research aims to develop a plastic waste-based roster product as an alternative solution to reduce plastic pollution while creating a functional and environmentally friendly product. This research used a quantitative approach with the Design of Experiments and Analysis of Variance method, along with the Newman-Keuls test to determine the effect of varying the proportion of plastic waste on the roster's compressive strength. The types of plastic used were High-Density Polyethylene (HDPE) and Polypropylene (PP), with three variations in the amount of plastic waste: 1.084 grams, 2.168 grams, and 4.336 grams. Additional materials used were sand, coarse aggregate, gypsum powder, cement, and water, the composition of which was constantly controlled. The manufacturing process includes plastic shredding, material mixing, molding, and compression testing using a Compression Testing machine type AMU 20. The results showed that a lower dose of plastic waste produced a higher compressive strength, with a maximum value of 8.04 MPa at a composition of 1.084 grams, while the highest composition produced the lowest compressive strength of 4.02 MPa. This study concluded that plastic waste can be utilized effectively in roster production, with a significant influence on product strength.
