The decision-making process in learners’ failure using fuzzy scale

This study aims to determine how to use an ambiguous scale to assess student performance and proficiency, whether students perform well or poorly in subjects such as reading comprehension, vocabulary, and punctuation. In this study, Sugeno Integral is a good choice for decision-making. Although other scales may be better than the one used, Sugeno Integral is easier to use than different scales, as evidenced by the results obtained.
