Abstract

Useful information system to support of business process an organization/company with no eception immigration authority. Business process that so far has been implemented have not use information technology maximally resulted in a fall in the passer the limits for the low service quality to the unfixed data storage and difficulty for finding data and produce reports. The purpose of the research are to design a cross platform information system architecture to support the business process carried out by the immigration authorities on three (3) Integrated Cross Border Posts (PLBN) under the control of the Class II Immigration Office of Atambua, East Nusa Tenggara. For the purposes of the architecture planning was using the framework of TOGAF ADM based on mapped problems, while the design of the information system is based on the PIECES framework. Information systems that proposed aims to solve the problems faced by and to support policy and the government's national strategies in the management of the border region. It is expected that the design of cross platform information system applied to linking immigration offices, immigration officers in PLBN and the passer. The results of this research are expected to be implemented in support of the business process on the immigration authorities with linking immigration offices, immigration officers in PLBN and the passer and also to improve the services of the immigration officer.

Abstract

Investasi teknologi informasi (TI) menjadi salah satu strategi penting dalam meningkatkan efisiensi dan efektivitas operasional di berbagai sektor, termasuk di sektor pendidikan. Penelitian ini bertujuan untuk menganalisis kelayakan investasi pengembangan dan penerapan sistem e-learning di SMAN 01 Sanggau menggunakan metode Cost Benefit Analysis (CBA). Metode ini membandingkan total biaya yang dikeluarkan dengan besarnya manfaat yang diperoleh, baik manfaat berwujud (tangible) maupun tidak berwujud (intangible). Data diperoleh melalui berbagai metode yakni observasi, wawancara, dokumentasi, serta studi literatur. Hasil penelitian menunjukkan bahwa pengembangan dan penerapan sistem e-learning memberikan berbagai manfaat signifikan, seperti penghematan biaya operasional (ATK, percetakan, pelatihan guru), efisiensi waktu administratif hingga 75%, serta peningkatan efektivitas proses pembelajaran. Selain itu, manfaat tidak berwujud meliputi peningkatan kualitas pendidikan, aksesibilitas materi pembelajaran, dan interaksi antara guru, siswa dan orang tua menjadi lebih efektif. Analisis keuangan menggunakan indikator seperti Net Present Value (NPV), Return on Investment (ROI), dan Payback Period (PP) menunjukkan bahwa investasi ini layak dieksekusi karena manfaat yang diperoleh melebihi biaya yang dikeluarkan.

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.
