Abstract: Indonesia known as an archipelago where sea transport is transport is dependable by for shipping Inter Island. The height of waves is one of the causes of accidents at sea transportation for that this research will be carried out the prediction of a wave height to minimalise of the accident in sea transportation. Neural network is one of algorithm intelligent for nonlinear advantage predictions which having blackbox can studying the relations between input and output system. Neural network is very suitable as prediktor the waves. The prediction results show that the neural network has small’s RMSE.
