The research study developed an alternative composite roof tile by utilizing waste plastics such as polypropylene as a binder of fine perlite as fine aggregates and dried coir fibers as reinforcement fibers that aims to address environmental problems and the death of marine mammals caused by solid waste and plastic pollution and to provide roofing material that can be used as a substitute for concrete roof tile in terms of flexural strength, compressive strength, and water absorption. The prototype, with dimensions of 35.56 cm x 30.48 cm and a weight of 2500 grams, was developed by melting polypropylene, mixing it with fine perlite and dried coir fibers, and molding it into a metal molder, which was then cured for 3-4 days. The study used two mixtures: A with PP 96.5%, fine perlite 2%, and dried coir fibers 1.5%; B with PP 96.5%, fine perlite 1.5%, and dried coir fibers 2%. Mixtures A and B both achieved passing results in the flexural strength, compressive strength, and water absorption tests using the standards of ASTM D790, ASTM D695-15, and ASTM C406. However, mixture A achieved higher compressive and flexural strength while obtaining less water absorption than mixture B. The prototype was evaluated by 18 individuals, including civil engineers, CET students, and staff from two hardware stores. It was deemed highly acceptable in aesthetics, workability, functionality, economy, safety, and efficiency, indicating its potential as a roofing material.
