Besides the dull appearance, potential errors also occur due to saturation. To help the work, we need a computer method to recognize each letter to present an answer option (e.g. a, b, c, d and e), save it as a pattern and use as a comparison when reading the questionnaire answer sheets, so that each respondent answer can be recognized by the computer. To create a software model for this purpose we use the concept of Artificial Neural Network (ANN) by using the Back PropagationenNeural NetworksBack PropagationPattern RecognitionUR-Proceedings
