One of the obstacles on the path to the sea is a wave heights, the wave can cause in accidents sea that the ship sank. To minimize accidents, this study will make a neural network algorithm to predict wave heights in the next hour. The advantages of this neural network that has a black box that can process data input and output. The prediction results show that the neural network has small’s RMSE.
