Abstract The types of wood in Banda Aceh used was seumantok, meranti , and sembarang wood. The process of wood leaves sawdust. The sawdust becames rubbish and could pollute the environment. There was five quality of woods, namely quality I - quality V. The purpose of this study is to optimize the sawdust of seumantok (quality I), meranti (quality II), and sembarang wood (quality III) to be processed into wood ash as a substitute for a part of cement in concrete with its percentage were 5% and 10%. The research method was experimentally in a laboratory-based on ASTM (American Society for Testing and Materials) and ACI (American Concrete Institute). The maximum diameter of the aggregate was 25.4 mm, and the compressive strength of concrete was 14.5 MPa with 21 specimens of cylindrical concrete. Concrete compressive strength results at 28 days with 5% wood ash variation and 10% respectively for quality I were 15.83 MPa and 14.20 MPa, quality II was 13.56 MPa and 12.75 MPa, and quality III were 13.79 MPa and 10.75 MPa. While the normal compressive strength of concrete was 15.86 MPa.
