Paving block is one of the construction productions commonly used for pavement, yards, sidewalks, and others. Paving block molds in rectangular shape with a size of 20 cm × 10 cm × 6 cm as many as 36 pieces of plan quality, which is 8.5 MPa. Paving block printing using hydraulic press. The percentage of corn husk pulp ash as a substitute for cement is 0%, 2%, 4%, 6%, 8% with a mixture of 1 cement: 3 sand. Paving blocks are tested at 28 days of age and tested for compressive strength and water absorption. For compressive strength testing, paving blocks are cut into cube shapes measuring 5 cm × 5 cm × 5 cm, and tested using Unit Testing Machine (UTM) compressive testing equipment, while for water absorption testing on paving blocks using the initial mold size. In this study, a normal paving block compressive strength value of 2.19 MPa was obtained. The highest compressive strength value is obtained in 2% incremental variation with a compressive strength value of 2.03 MPa. As for normal paving block water absorption, an absorption value of 813.30% was obtained. The smallest water absorption value is obtained in a variation of 4% addition, which is 10.70%.
