520			_aConcrete floor tile is a durable flooring material composed of cement, aggregates, and sand, providing exceptional durability and longevity. However, concrete floor tiles have some drawbacks, including voids and cracks that can weaken the tile. This study examines the effect of corn cob ash as a filler and PET fiber as reinforcement on concrete floor tiles. The experiment incorporates a cement-sand-aggregate ratio of 1:1:1.5 and tests five different percentages of corn cob ash (0%, 2%, 4%, 6%, and 8%) relative to the weight of the cement, along with 0.5% of PET fiber used as reinforcement by weight of the concrete floor tile, which measures 20 mm in length. The tile had dimensions of 203.20 mm x 203.20 mm x 25.40 mm and underwent 28 days of curing. The concrete floor tile underwent testing to determine its properties according to ASTM C1731-21, which included a Compressive Strength Test, Flexural Load Test, Water Absorption Test, Ultrasonic Pulse Velocity Test, and Ultrasonic Pulse Echo Test. The test results show that Mix 3 has the most optimal mix design, achieving the highest flexural strength while maintaining the lowest water absorption. According to the Ultrasonic Pulse Velocity Test and Ultrasonic Pulse Echo Test, mix five indicates that there are no voids, honeycombs, or cracks in the concrete floor tile. All mix designs passed the required standard for the compressive strength of the concrete floor tile. The evaluation has an average score of 4.46, which is considered "Very Acceptable."
