The use of concrete as the main material in the construction does not mean it has no weaknesses. The brittle, low-density concrete properties make it collapse unexpectedly. In this work, a concrete innovation was performed to increase the compressive strength by the addition of rice husk ash as cement substitution that contains 92.31% of SiO2 and by the addition of banana tree bark. The proportion of rice husk ash used was obtained from preliminary tests to determine the proportion of rice husk ash by 5%, 7%, 10%, 12% and 15% of the cement’s weight. The result of the proportion which yielded the optimum concrete compressive strength by 24.4 MPa in the proportion of rice husk ash by 7%, then was made with the same ash content with banana tree bark fiber variation 0%; 1.5%; 2% and 3%. The Result of the test concluded that the addition of banana tree bark fiber can decrease the compressive strength and tensile strength of concrete because it is caused by the fibers that make hard concrete become solid. However, for all proportions of fiber, it still qualifies as the minimum tensile strength to be achieved i.e. 8% of the compressive strength of the plan.
