Various patterns on the character letters have various handwriting models made by the author. The problem that arises in the process of hand recognition is how an introduction can recognize various letters with size, thickness, shape, and slope between one author and another. One of the algorithms on an artificial neural network is backpropagation which has undergone several significant changes made by a neural network that is continuously leveled up to a certain level to be able to generalize. The test results of the block letter handwriting character recognition system from 10 tests only 1 letter that was not legible, namely the letter D. The test resulted in the lowest error of 0.066672. The results of the test are 90% this means that the level of accuracy between the test data and produces 90% this means that the level of accuracy of the test accuracy between the test data and the training data yields 90%. The implementation of the Backpropagation Neural Network method with small epochs in carrying out something in a pattern can cause errors that occur during training. By applying the Backpropagation Neural Network method, you will get a higher success rate for training than new data} }
