Abstract

Universitas Widya Dharma Pontianak merupakan perguruan tinggi yang dalam pelaksanaan segala proses bisnisnya telah memanfaatkan bantuan teknologi informasi, salah satunya yakni pada proses penerimaan mahasiswa baru (PMB). Adapun teknologi yang berbasis website tersebut telah digunakan dan memberikan kepuasan bagi pihak perguruan tinggi karena mempermudah proses penyajian informasi serta pengelolaan data yang berkaitan dengan penerimaan mahasiswa baru. Namun jika dilihat dari perspektif mahasiswa baru sendiri, penggunaan website tersebut belum pernah dievaluasi sehingga belum diketahui tingkat kepuasannya. Oleh karena itu, perlu dilakukan evaluasi untuk mengetahui hal tersebut sehingga dapat memberikan rekomendasi untuk peningkatan fungsi dan layanan dari website PMB. Evaluasi yang dilakukan menerapkan metode End User Computing Satisfaction (EUCS) dengan melibatkan 292 responden dari pengguna website yang merupakan mahasiswa baru pada periode tahun akademik 2024/2025. Berdasarkan hasil perhitungan TCR diketahui bahwa rerata nilai TCR dari setiap dimensi berada di atas 81% dan termasuk dalam kategori sangat tinggi, sehingga lima (5) hipotesis yang dibangun yaitu H1, H2, H3, H4 dan H5 yang masing-masing menyatakan bahwa hasil perhitungan nilai TCR dari dimensi konten, akurasi, format, kemudahan penggunaan dan ketepatan waktu termasuk dalam skala kategori sangat tinggi disimpulkan dapat diterima. Hasil tersebut menggambarkan persepsi positif dari para responden yang berarti bahwa tingkat kepuasaan responden sangat tinggi terhadap website PMB, sehingga website tersebut dianggap sangat berguna dan sangat layak untuk digunakan.

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

Penelitian ini mengkaji penerapan teknologi blockchain dalam sistem akademik di perguruan tinggi sebagai respons terhadap meningkatnya kebutuhan akan keamanan, transparansi, dan efisiensi dalam pengelolaan data akademik. Tujuan utama penelitian ini adalah menganalisis secara sistematis bagaimana blockchain telah digunakan, sedang diterapkan, dan berpotensi diintegrasikan dalam berbagai proses akademik, termasuk verifikasi kredensial, pengelolaan rekam jejak belajar, serta interoperabilitas data antar-institusi. Menggunakan pendekatan systematic literature review, penelitian ini menerapkan protokol pencarian, seleksi, dan sintesis literatur secara ketat untuk mengidentifikasi publikasi relevan dalam lima tahun terakhir. Hasil kajian menunjukkan bahwa meskipun blockchain menawarkan manfaat strategis seperti imutabilitas data, desentralisasi, dan otomatisasi melalui smart contract, implementasi praktisnya dalam konteks perguruan tinggi masih terbatas pada verifikasi sertifikat dan belum banyak menjangkau keseluruhan siklus akademik. Temuan juga mengungkap adanya sejumlah tantangan, termasuk kesiapan infrastruktur, regulasi, dan kapabilitas institusional yang masih rendah, khususnya di negara berkembang. Penelitian ini memberikan kontribusi teoretis melalui integrasi konsep teknologi blockchain dengan karakteristik sistem akademik modern, serta kontribusi praktis berupa pemetaan peluang dan hambatan implementasi yang dapat menjadi acuan bagi institusi pendidikan tinggi dan pembuat kebijakan dalam merencanakan adopsi teknologi secara lebih terarah dan berkelanjutan.   This study examines the application of blockchain technology in academic systems at universities in response to the increasing need for security, transparency, and efficiency in academic data management. The main objective of this study is to systematically analyse how blockchain has been used, is being implemented, and has the potential to be integrated into various academic processes, including credential verification, learning record management, and inter-institutional data interoperability. Using a systematic literature review approach, this study applies strict literature search, selection, and synthesis protocols to identify relevant publications from the last five years. The results of the study show that although blockchain offers strategic benefits such as data immutability, decentralisation, and automation through smart contracts, its practical implementation in the context of higher education is still limited to certificate verification and has not yet reached the entire academic cycle. The findings also reveal a number of challenges, including infrastructure readiness, regulations, and low institutional capabilities, especially in developing countries. This research provides a theoretical contribution through the integration of blockchain technology concepts with the characteristics of modern academic systems, as well as a practical contribution in the form of mapping the opportunities and obstacles to implementation, which can be used as a reference for higher education institutions and policymakers in planning a more focused and sustainable adoption of the technology.

Abstract

The increasing demand for cloud computing services has led to the rapid expansion of cloud data centers, which consume significant amounts of energy and contribute substantially to global CO2 emissions. As the IT industry grows, the environmental impact of these data centers becomes an urgent concern. Green Cloud Computing (GCC) has emerged as a solution to mitigate this impact by focusing on energy efficiency and reducing carbon footprints while maintaining the necessary functionality and performance of cloud infrastructures. However, traditional blockchain consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS) face limitations regarding energy consumption and scalability, which exacerbates the environmental burden. This study proposes a quantum-inspired blockchain consensus algorithm designed to optimize energy consumption and reduce latency in cloud data centers. By integrating quantum principles such as superposition and entanglement, the algorithm enhances task scheduling and resource utilization, enabling more energy-efficient operations without sacrificing performance. Simulations in a green cloud environment showed that the quantum-inspired algorithm resulted in up to a 30% reduction in energy usage compared to traditional consensus methods, with a 40% improvement in consensus processing time. These results suggest that quantum-inspired algorithms hold significant potential for enhancing the sustainability of cloud infrastructures by improving energy efficiency and scalability. Furthermore, this study discusses the feasibility of implementing quantum-inspired algorithms on classical hardware, addressing challenges in scalability and integration into existing blockchain frameworks. The findings provide valuable insights into the potential of quantum-inspired technologies to drive energy-efficient solutions in cloud computing.

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.
