INTRODUCTION Higher education aims to produce educated people according to the existing criteria (Indrajit & Djokopranoto, 2006). Universities are expected to produce quality professionals in terms of knowledge, capital, and ethics (Apriani et al., 2017). The learning process can shape students' character as provisions in carrying out the world of work. However, in reality, the environment in higher education still has deviant behaviour. One of the problems in the university environment is academic fraud. According to the student team research at various universities in Bogor, 80% of students committed academic fraud (Murni & Pratiwi, 2020). Academic fraud is a form of bad behaviour that will hurt students (Padmayanti et al., 2017).
