Abstract: Plywood ash is one of waste material from plywood factory. Its bigger and cause contamination problem to the environment. The aim of this research to establish the potential of using plywood ash as substitution partial of cement in concrete. By reducing using of cement in concrete can reduce the effect of CO2 emission which produced from the cement factory. The sample material was formed of the cylinder of 15 cm in diameter size and 30 cm in height for testing of compressive strength after curing in 28 days. From the result of research known that plywood ash can be used as substitution partial of cement. Using of cement can be reduced by 10% to get compressive strength almost equal to normal concrete without plywood ash. Using of plywood ash up to 10% cause decrease of compressive strength and cause increase water absorption of concrete. The research to using waste material to reduce using of cement must continue to prevents environment contamination and reduce CO2 emission to the atmosphere.
