Tujuan dari penelitian ini adalah untuk mengetahui bagaimana audit sistem informasi berbasis komputer dapat mencegah terjadinya kecurangan (fraud). Metode yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan analisis deskriptif. Jenis -jenis teknik yang digunakan didasarkan pada penelitian literatur. Analisis data dilakukan oleh editor data, presentasi, dan urutan kompensasi data. Jika teknologi audit berbasis komputer meningkatkan pengawasan keuangan dan bertekad untuk mengetahui kemungkinan penipuan sebelumnya. Sistem uji berbasis komputer semakin banyak digunakan di dunia bisnis untuk meningkatkan transparansi dan mencegahnya (penipuan). Teknologi seperti Teknologi Bantu Komputer (CAAT), Kecerdasan Buatan (AI), dan analisis data memungkinkan penguji untuk menganalisis transaksi lebih cepat, lebih akurat dan lebih efisien daripada metode tradisional. Sistem ini dapat mengenali pola transaksi yang mencurigakan, mengurangi kesalahan manusia dan meningkatkan kontrol internal perusahaan. Namun, aplikasi menetapkan hambatan seperti sumber daya SDM yang terbatas, persyaratan pertemuan personel, ancaman dari keamanan data, dan biaya investasi yang tinggi. Oleh karena itu, strategi yang tepat diperlukan untuk mengoptimalkan metode audit untuk menciptakan sistem keuangan yang lebih bertanggung jawab, lebih efisien dan transparan.

Internal access abuse is a form of fraud that can significantly harm a company, both financially and reputationally. Therefore, it is essential for companies to implement effective preventive measures to protect the integrity of their information systems and assets. This article discusses various strategies that can be applied to prevent fraud, including the implementation of strong internal controls, segregation of duties, and strict access controls. Additionally, features such as audit trails, clear security policies, and the use of advanced security technologies are key elements in detecting and preventing access abuse. Building a culture of ethics and transparency within the company, as well as providing ongoing education and training to employees, is also crucial for raising awareness of fraud risks. Conducting regular audits and risk assessments can help companies identify potential weaknesses in their internal control systems. By adopting a comprehensive and integrated approach, companies can protect their assets, maintain operational integrity, and build trust among employees and stakeholders, ultimately contributing to the long-term success of the organization

The purpose of this study is to analyze the implementation of Accounting Information Systems (AIS) in managing the company's revenue cycle control. The revenue cycle involves a series of crucial activities such as receiving orders, shipping goods, billing, and receiving payments, which require strict supervision to reduce errors and manage existing risks. Without the implementation of AIS, some common problems that often arise in managing the revenue cycle include inaccurate information, loss of employee data archives, difficulty in detecting errors in supervision, as well as limited reporting supervision and invalid data. As a solution, AIS can be implemented to increase data processing capacity, improve storage space, and improve control between parts of the organization. This study investigates the implementation of AIS in recording revenue transactions and its impact on internal control, such as preventing fraud, increasing data accuracy, and accelerating business processes. The results of the study are expected to provide an understanding of how the implementation of AIS can improve revenue cycle control and reduce risks associated with large business transactions.
