Concrete is one of the materials commonly used for building construction. The rapid development of infrastructure in Indonesia, as it is today, causes the need for concrete use to increase . The compressive strength test used a total of 36 samples consisting of normal concrete and 3 variations in the ash content of corn cobs starting from 5%; 10%; 15%. The test will be carried out at the age of 28 days. Based on data analysis from the results of the compressive strength test, the values for each normal concrete and ash variation are 5%; 10%; 15%; successively at age. The compressive strength value at the age of 28 days is 19.67 MPa; 19.74 Mpa; 21.81 Mpa; 18.98 Mpa. With an increase in the maximum compressive strength of 23.714 MPa at an optimum level of 10%. where the added material content of 10% based on the age of the concrete for 28 days actually has the highest compressive strength value compared to the added content of other corncob ash. This of course will also have an effect if the temperature variations of the burning of corncob ash waste are used differently.
