<![CDATA[The rapid development of infrastructure has led to an increase in demand for infrastructure materials. The use of natural materials in concrete production is becoming increasingly uncontrolled with the continuation of current infrastructure development. With the increase in marble production in Indonesia, the marble powder waste produced has become an environmental problem that needs to be addressed. This study aims to determine the compressive strength of concrete with the addition of 0%, 15%, 25%, and 35% marble powder waste. The research design used in this study is quantitative with a experimental research type. Data analysis uses the ACI (American Concrete Institute) standard. The test specimens in this study were made using cylinders with a diameter of 15 x 30 cm with a planned concrete compressive strength of ƒʾϲ 21.7 MPa. The percentage of marble powder waste used varied between 0%, 15%, 25%, and 35% with a planned age of 7 and 28 days. The results showed that the addition of marble powder waste affected the compressive strength of the concrete, with an optimal value of 23.79 MPa achieved at 28 days with a variation of 15%.]]>
