<![CDATA[Fraud in financial management is one of the risks that frequently arises in manufacturing companies and can undermine the integrity of financial statements and stakeholder trust. This study aims to analyze the effect of internal control on fraud prevention and to examine the role of business ethics as a mediating variable at PT Wahana Interfood Nusantara Tbk. The research employs a quantitative approach using the Structural Equation Modeling Partial Least Square (SEM-PLS) method. Data were collected through questionnaires distributed to 50 respondents involved in finance, accounting, and operational functions, and subsequently analyzed using measurement models and structural models.The results indicate that internal control has a positive and significant effect on fraud prevention. Furthermore, internal control is proven to have a positive and significant effect on business ethics, and business ethics also has a positive and significant effect on fraud prevention. Another important finding is that business ethics is able to mediate the effect of internal control on fraud prevention, thereby strengthening the relationship between these two variables. This suggests that the effectiveness of internal control is not only determined by the systems and procedures implemented by the company but also heavily depends on the ethical values and integrity of the employees who execute them.]]>
