Self-compacting concrete (SCC) is an innovation of conventional concrete that is able to fill spaces in the mold without the compaction process, and is able to flow by itself.This type of concrete can solidify itself and possess high workability so it does not need a vibrator and compactor tool to compact it. Self-compacting concrete must be able to withstand compressive and bending forces so that the building does not experience structural failure, stable and safe. Flexural strength can be predicted using fuzzy logic. Fuzzy logic is a logic for solving problems by mapping input space into the output space. This study aims to determine the predictions of the flexural strength of self-compacting concrete using fuzzy logic to the amount of material used. Modeling is done by the fuzzy mamdani method found in the MATLAB software toolbox with the membership function of the trapezoidal curve representation. The prediction of the next flexural strength will be compared with secondary data obtained from previous research on self-compacting concrete. The modeling results show that the predictive value of fuzzy logic flexural strength approaches the laboratory flexural strength with an average percentage error of 5.79% and a deviation of flexural strength value of 4.20%, so that the flexural strength value is not much different.
