Abstract:    Many plywood factories were built in Indonesia. Plywood Ash is waste material from plywood factory. Wasting plywood ash cause contamination to the environment. The aim of this research to establish the potential of the using plywood ash as material addition in concrete mixture. Plywood Ash was sieved through laboratory sieve number 100 in order to remove any organic impurity and larger size particles. Variation of plywood ash addition used 0%, 10%, 20 %, 30 % and 40 % from weight of Portland Cement. The specimen was formed of the cylinder 15 cm in diameter size and 30 cm in height for testing of the compressive strength and split tensile strength test. The specimens test conducted with a curing in water until 28 days. The result of this research known that plywood ash can be used as material addition in concrete mixture. For addition of Plywood ash 10 % of cement, it obtains the maximum compressive strength and split tensile strength of concrete. Using plywood ash more than 20 % will decrease compressive strength and split tensile strength lower than control concrete. The research of the using waste material must be continued to prevents environmental pollution.
