Abstract

Document archiving is a very important supporting factor for a company's business processes. In accordance with KUHD, which states that the document retention period in a company is 10 years, then of course company’s must apply the right document archiving method to ensure the condition, availability and ease of document retrieval. The status of document archiving at PT XXX so far still uses the form of hardcopy, which certainly begins to take up document storage space. In addition, searching for documents takes time and effort, even though the archives are well organized and classified. Another obstacle is that electronic mail and mail attachments sent via electronic mail are also difficult to archive with a clear classification. By taking advantage of technological developments, various types of documents such as letters, reports, and other types of documents can be archived not only in the hardcopy form, but also in the form of digital copies (softcopy). Therefore, PT. XXX needs a computer application that can help archive documents digitally, both for documents in the hardcopy form and documents from electronic mail. The goal is that PT. XXX can implement good document governance so that it can support the business processes carried out. Through this research, the application will be built by applying the GXP development model, which will produce various document management features, namely scanning, synchronization with electronic mail, classification, storage, and search and digital document preview. Through the results of user testing, it is found that the application through its various features can help PT. XXX to manage document archives and support its business processes.

Abstract

The high cost of ICT investment is often an obstacle to ICT implementation, especially for educational institutions with limited budgets. Without analysis, the risk of budget waste and incompatibility with the real needs of the institution becomes higher. This study aims to assess the readiness of information and communication technology (ICT) investment using an integrative approach that combines Cost-Benefit Analysis (CBA), Technology-Organisation-Environment (TOE) Framework, and OODA Loop. This approach is designed to provide a comprehensive evaluation of economic, technological, organisational, and decision-making dynamics in ICT investment. The research method uses a qualitative approach with data collection through observation, interviews, and documentation studies. The analysis is carried out by integrating the results of CBA to assess the feasibility of investment, the TOE Framework to identify factors influencing technology adoption, and the OODA Loop to understand the iterative and adaptive decision-making process. The research findings indicate that based on the CBA analysis, the ICT investment in the form of developing and implementing an e-learning system at SMAN 01 Sanggau is highly feasible to execute. However, from the TOE Framework perspective, the organisation's readiness to adopt the e-learning system is still partial with some shortcomings. From the OODA Loop perspective, the investment is deemed feasible after considering: financial calculations showing benefits through metrics such as NPV, ROI, and PP, non-financial benefits such as improved access to learning and educational quality, and proactive risk mitigation against technical, financial, and operational challenges.

Abstract

The escalating complexity of computer networks and cybersecurity threats demand analytical approaches capable of systematically and measurably representing network structure. Discrete mathematical graph theory offers a formal framework for modeling network topology as nodes and edges, thus potentially supporting more effective intrusion detection and firewall placement optimization. This research aims to conduct a Systematic Literature Review of publications from 2022–2026 to identify graph theory applications in intrusion detection, evaluate the most effective graph-based firewall optimization methods, and map research gaps and future development trends. The methodology employed follows the SLR protocol with stages of systematic search across reputable databases, selection based on inclusion-exclusion criteria, and analysis through descriptive-comparative meta-analysis, thematic meta-synthesis, and content analysis. Results show the dominance of weighted graphs and structure-based learning approaches for network anomaly detection, as well as firewall optimization modeling through integer linear programming and graph heuristics. This research contributes to presenting an integrated synthesis between intrusion detection and firewall optimization within discrete graph framework, and provides conceptual foundation for developing adaptive network security models based on mathematical structure.
