The growing accumulation of plastic waste in coastal regions like Pangkajene and Islands Regency has become a pressing environmental concern due to inadequate waste management systems. This study proposes an innovative solution by utilizing post-consumer plastic waste (PET, HDPE, and LDPE) combined with local Pinrang sand to produce lightweight, eco-friendly paving blocks. The experimental method involved melting shredded plastic and blending it with sand in various ratios (1:1, 1:2, 1:3), then molding and testing the compressive strength based on SNI 03-0691-1996 standards. Results showed that the 1:1 composition achieved the highest average compressive strength of 9.84 MPa among plastic-based samples, while conventional blocks reached up to 34.80 MPa. Plastic waste paving blocks met Class D criteria, suitable for light-use pavements, while conventional ones met Class B. Although the mechanical strength of plastic-based blocks was lower, their environmental benefits and lighter weight make them suitable for garden paths and pedestrian areas. This study affirms the potential of integrating plastic waste into construction materials, offering a sustainable and practical response to local waste challenges
