Abstract

Fraud represents a critical threat to organizational integrity, particularly within state-owned enterprises in Indonesia. This study aims to examine the influence of whistleblowing systems and internal audit on fraud prevention in PT Angkasa Pura Indonesia. Employing a quantitative approach with Partial Least Squares Structural Equation Modeling (PLS-SEM), the research evaluates the relationships of whistleblowing and internal audit to fraud prevention. Data were collected via a structured questionnaire and validated through reliability and validity tests. The findings reveal that whistleblowing systems and internal audit have significant positive effects on fraud prevention, with internal audit showing a stronger influence (β = 0.594; p < 0.001) compared to whistleblowing (β = 0.335; p < 0.001). The structural model explains 75.2% of the variance in fraud prevention outcomes. Dominant indicators were identified: accessibility of reporting channels (whistleblowing), compliance with audit international standards (internal audit), and consistent enforcement of ethical sanctions (fraud prevention). The study concludes that integrating effective whistleblowing mechanisms and high-quality internal audits is essential to strengthening fraud prevention strategies. These mechanisms must be supported by a governance environment that emphasizes ethical enforcement, transparency, and accountability. Practical implications are offered for public enterprises seeking to minimize fraud risk through internal governance reform

Abstract

KUBE Putri Duyung faces productivity and marketing constraints due to manual packaging methods and traditional sales strategies, leading to salted fish stockpiling and declining selling prices. This community service initiative aims to enhance the group's competitiveness through the integration of packaging technology and digital marketing. The methods employed include socialization, training, technology implementation (drying machine, vacuum sealer, continuous sealer), intensive mentoring, and ongoing evaluation. As a result, production capacity increased by 25-50%, time efficiency improved by 25%, and sales grew by 30% through digital platforms. This program successfully transformed KUBE Putri Duyung into a competitive and sustainable MSME in the Society 5.0 era, aligning with the achievement of SDGs numbers 8, 9, and 12.
