Abstract: Along with the advancement of time, technology in the field of building construction, especially concrete manufacturing, is also experiencing very rapid development, almost every aspect of human life is always associated with concrete. The use of added materials has been done in the process of concrete admixture. Based on this, this study aimed to determine the increase in optimal compressive strength of concrete with additional material of husk charcoal and compressive strength of the plan at 28 days is 20 MPa. In this study using the percentage variation of husk charcoal 0 %, 2 %, 4 %, and 6 % by weight of cement. The analytical review of this research is the compressive strength, with concrete cylindrical specimens having a diameter of 15 cm and a height of 30 cm. The concrete mix planning method uses the Indonesian National Standard (SNI) method. The material for this experiment is rice husk which is made into charcoal by manual process. After testing and research, the results show that the use of rice husk charcoal results in reduced workability because the absorption capacity of rice husk is quite high, and the strength of concrete with the addition of husk charcoal by 2 %, 4 %, and 6 % concrete increases its strength from compressive strength concrete plans of 20 MPa. Concrete compressive strength with a mixture of 2% husk charcoal produces compressive strength of 24, 3 MPa, there is an increase of 4, 3 MPa with the addition of husk charcoal by 2 %.
