Abstract

Data protection in higher education remains a pressing concern as student records and program registration data are frequent targets of cyber incidents. This paper presents the design and implementation of AES-256 to secure the registration feature within an academic information system (AIS). Specifically, this study delivers three main contributions: a modular cryptographic implementation at the controller level, a granular field-level encryption policy for sensitive attributes, and a validated security mechanism. We integrated a cryptographic module into a Fastify (Node.js) backend and PostgreSQL datastore. The results demonstrate the fulfillment of these contributions: first, the modular implementation effectively isolates encryption logic from the database layer; second, the field-level policy successfully secures sensitive PII while maintaining 100% query efficiency for non-sensitive data; and third, the security mechanism was validated through 17 white-box scenarios and dual-layer API testing. These results confirmed 100% functional correctness in encryption/decryption cycles and robust handling of invalid data inputs. The study contributes a practically deployable pattern for field level encryption in university information systems.

Abstract

The increasing use of E-government (SPBE) has accelerated digital change in public administration but has also created real risks to information security. This study aims  to evaluate the level of information security risk management maturity at the Central Java Provincial Data Center by merging the Indonesian SPBE Risk Management framework (PermenPANRB No. 5/2020) with SNI ISO/IEC 27001:2022. The evaluation utilized a descriptive qualitative method, backed by observations, interviews, and a survey-based maturity assessment that aligns with the control areas of ISO/IEC 27001. Findings reveal that the overall maturity sits between “Managed and Measurable” (Level 4) and “Optimized” (Level 5), indicating that most procedures are organized, documented, and consistently observed; however, some sub-controls still need enhancement, especially those related to incident response, ongoing improvement, and staff awareness. This research emphasizes the necessity for a more flexible security governance approach and contributes by integrating national regulatory guidelines with global information security frameworks to enhance the maturity assessment of government data centers.

Abstract

In the rapidly evolving retail industry, executives are increasingly challenged to make timely and accurate decisions based on complex and dynamic data. This study aims to design a strategic information system (SIS) that can support executive-level decision-making by integrating key business intelligence components. The proposed system is developed using a user-centered approach and incorporates a web-based dashboard that visualizes real-time sales, inventory, and customer behavior analytics. Through a case study at a medium-sized retail company, the system was evaluated based on its usability, effectiveness, and impact on decision quality. The results demonstrate that the implementation of the SIS significantly improves the speed and accuracy of executive decisions, particularly in areas related to inventory control, sales forecasting, and strategic planning. This research contributes to the advancement of digital decision-support tools in the retail business environment and provides a model that can be replicated in similar organizational contexts.

Abstract

Financial reporting transformation is a crucial requirement for Micro, Small, and Medium Enterprises (MSMEs), particularly in improving the accuracy, efficiency, and quality of the information presented. Accurate financial reporting plays a crucial role in supporting decision-making, business planning, resource management, and improving access to financing. This study aims to examine the transformation of accurate financial reporting in accordance with Financial Accounting Standards (SAK) at Haji Tenry Digital Printing. The method used in this study is descriptive. Data collection techniques were conducted through interviews, observations, and documentation of financial recording and reporting activities before and after the transformation. The results show that before the transformation, financial recording was still done manually using cash books and physical notes, making it susceptible to recording errors, lost documents, and delays in report preparation. After the transformation using the SIAPIK application, the recording process became more orderly, accurate, and efficient. In addition, this transformation also increases business actors' awareness of the importance of financial reporting in making more appropriate business decisions. Digitizing financial reporting systems has been proven to accelerate work processes, improve information reliability, and help business owners understand their overall financial condition. In conclusion, the use of the Financial Information Recording Application Information System (SIAPIK) has a positive impact on the quality of financial reporting information. It is recommended that this system be implemented continuously, along with training for staff to ensure optimal application utilization.
