Good quality concrete is concrete that has high compressive strength, and one of the efforts to increase the compressive strength of concrete can be done by using sugarcane ash as an added ingredient. Bagasse ash has the same content as the main ingredients for forming portland cement, namely silica (SiO2) and ferrite (FeO2), so that it can be used as a pozzolan and can also increase the strength of concrete. This study aims to determine the magnitude of the increase in the compressive strength of concrete, and also to determine the percentage of addition of bagasse ash to obtain the optimum value of concrete compressive strength. The method used in this research is to study the literature on various matters and information related to the research to be carried out. Based on the research results, it was found that the greater the percentage of addition of bagasse ash as a substitute material, the lower the compressive strength of the concrete obtained. Variations in the percentage of bagasse ash can affect the quality of the concrete obtained at the age of 28 days, namely concrete with 6% bagasse ash obtained a compressive strength of 24.39 MPa and concrete with 8% bagasse obtained a compressive strength of 21.49 MPa. Concrete added with 6% bagasse ash has a high characteristic compressive strength but for concrete with the addition of 8% bagasse ash, the characteristic compressive strength of concrete is low, compared to normal concrete without substitutes. In normal concrete, the compressive strength is 25.58 MPa.
