Abstract

Stress represents a prevalent psychological challenge among final- year university students, particularly during thesis completion. Academic pressure, social demands, and future uncertainty trigger stress that negatively impacts mental health. Social media, especially TikTok, is increasingly utilized as a coping mechanism to reduce stress through entertainment, educational, and motivational content. This study aims to analyze TikTok content utilization as a coping strategy for stress reduction among final-year students using a classification method. This quantitative research employed a survey approach with a population of 342 active TikTok users among final- year students at Sari Mulia University. Data were collected through an online questionnaire covering variables including content type, duration, features used, and psychological indicators such as anxiety, emotions, escapism, and coping effectiveness. Data preprocessing included one-hot encoding, SMOTE, and normalization, followed by classification using Support Vector Machine with RBF kernel optimized through GridSearchCV. Results revealed very high correlations among psychological variables (r ≈ 0.93–1.00), while correlations between content type and stress reduction were relatively low (0.00–0.15). Some pure entertainment content showed negative correlations with psychological improvement. The SVM model achieved high classification accuracy of approximately 94%. This study demonstrates that TikTok can serve as a short-term stress coping tool for final-year students, though its effectiveness depends heavily on the type of content consumed. Educational and motivational content shows greater potential for stress reduction compared to pure entertainment content. This research contributes to understanding digital mental health support mechanisms and provides insights for developing healthier media consumption strategies among university students.

Abstract

This study discusses the design of the integration of LAN, WAN, and WiFi network systems with centralized management and the implementation of Network Monitoring System (NMS) in Building E of Sari Mulia University with an area of ±600 m². The initial state of the network that is still running separately, without clear segmentation and without real-time monitoring, leads to limited network visibility, connectivity disruptions, and uneven WiFi distribution. This study aims to design and develop an integrated network system that combines LAN, WAN, and WiFi infrastructures with centralized management and NMS to improve network performance, security, and management efficiency. The method used is the network design method which includes needs analysis, network architecture design, device implementation and configuration, and system performance testing. Network integration is carried out through the implementation of a managed switch-based backbone, Virtual Local Area Network (VLAN) segmentation, strengthening security using firewalls and VPNs, and continuous network monitoring using NMS. The design results show an increase in connection stability, network security, and infrastructure management efficiency, with a ≥99.5% uptime and even WiFi coverage throughout the building, so that this system design is considered feasible to be applied as an integrated network solution in the educational institution environment.

Abstract

The advancement of information technology in higher education requires a reliable network infrastructure to support academic, research, and administrative activities. This study aims to design a computer network infrastructure for Building E at Sari Mulia University using the Waterfall model. The research includes needs analysis, system design, simulation-based implementation with Cisco Packet Tracer, and performance evaluation. The needs analysis identifies user requirements, devices, and applications to ensure the network supports high-speed internet, central server connectivity, and e-learning systems. The proposed design uses a hierarchical topology with core, distribution, and access layers, along with VLANs to optimize data traffic and reduce congestion. The simulation results showed that the network design performed as expected, with a success rate of 90-95%. However, improvements are needed, particularly in the wireless network (WLAN), where coverage was insufficient in certain areas due to limited access points and physical barriers. In conclusion, the network design effectively supports the university's academic and administrative needs, with room for growth and future technology integration.

Abstract

The implementation of the Indonesian Standard Quick Response Code (QRIS) has driven the growth of cashless payment systems in Indonesia through interoperability and expanded financial inclusion. However, the QRIS security mechanism still has limitations, particularly due to the use of CRC16-CCITT as the sole data integrity check. CRC16 is not designed to withstand intentional data manipulation, thus opening up opportunities for QR Code substitution-based phishing attacks and undetected transaction amount manipulation. This study aims to evaluate a hybrid security model that combines Hash-based Message Authentication Code (HMAC) with the SHA-256 algorithm and dynamic tokenization to improve QR Code payment security. The method used is an experimental approach based on software simulation by comparing the existing CRC16-based system with the proposed system based on HMAC-SHA256 and tokenization. Testing was conducted through several attack scenarios, including transaction amount manipulation and replay attacks. The test results show that the CRC16 mechanism has a high detection failure rate, where the manipulated QR Code is still considered valid as long as the checksum is recalculated correctly. In contrast, the HMAC-SHA256 mechanism is able to consistently detect all payload changes due to the use of a secret key. Dynamic tokenization has also proven effective in preventing the reuse of expired QR Codes without disrupting the user experience. In conclusion, the integration of HMAC-SHA256 and dynamic tokenization significantly improves the resilience of the QR Code payment system against phishing attacks and data manipulation, and has the potential to become the basis for strengthening the security of QRIS in the future.

Abstract

The rapid growth of digital payment systems and online transaction services has intensified the need for stronger mechanisms to protect sensitive user data from interception, leakage, and unauthorized access. Although Transport Layer Security (TLS) is widely adopted to secure communication channels, it primarily protects data during transmission and does not fully address risks arising from compromised servers or application-layer vulnerabilities. This study proposes and simulates an end-to-end secure channel architecture that integrates client-side encryption using the Advanced Encryption Standard in Galois/Counter Mode (AES-GCM) with the TLS 1.3 protocol to provide layered security. A web-based simulation was developed using HTML, CSS, and JavaScript with the Web Crypto API to illustrate the complete workflow, including client-side key generation, application-layer encryption, TLS 1.3 handshake, secure channel establishment, transport-layer encryption, and server-side processing. The simulation also implements a zero-knowledge mode, ensuring that the server does not possess the client-side encryption key and therefore cannot decrypt sensitive data at the application layer. The experimental results indicate that separating cryptographic keys between the application layer and the transport layer significantly enhances confidentiality and minimizes the impact of key compromise or server-side breaches. Furthermore, the visualization provided by the simulation helps clarify the interaction between client-side encryption and TLS 1.3 mechanisms, making it a useful educational and analytical tool. Overall, this study demonstrates that combining AES-GCM-based client-side encryption with TLS 1.3 offers a robust and practical approach for securing digital payment systems and other applications requiring high levels of data protection.
