Lightweight concrete is concrete that has a lighter specific gravity than normal concrete. Foam concrete is one of the types of lightweight concrete. Foam concrete is made through a physical or chemical process that involves adding air or gas to the slurry. Glass powder can be utilized as a filler. This study uses variations in the percentage of glass powder 20%, 30%, and 40% with a glass powder size of 50 Mesh, the volume ratio of foam and slurry used is 0.3 and 0.7 with a w/c variation of 0.3; 0.4; 0.5; 0.6; and 0.7. Fresh concrete testing in the form of setting time test and slump flow test, while for hard concrete testing in the form of testing compressive strength, specific gravity, and modulus of elasticity. Setting time test on lightweight concrete with 20% GP percentage variation value; w/c 0.3 with a value of 161 minutes has the fastest binding time compared to other w/c variations. Based on the slump flow value, the specimen with a variation of 40% GP percentage; w/c 0.7 has the highest workability value compared to other variations. The specific gravity value of the specimen with 20% GP percentage variation; w/c 0.3 on the 28th day has the largest value compared to other variations, which is 1519.5 kg/m3. The most optimal compressive strength value is obtained when the specimen with a percentage variation of GP 20%; w/c 0.5 with a compressive strength value of 3.18 MPa. The largest value for the modulus of elasticity was obtained in the specimen with a percentage variation of GP 20%; w/c 0.5 with a value of 8134.66682 MPa. The concrete mixture that has the most optimal value is a lightweight concrete variation containing 20% glass powder as filler with a w/c variation of 0.5 which has a specific gravity of 1398 kg/m3, a compressive strength of 3.18 MPa, and an elastic modulus value of 8134.66682 MPa.
