Abstract

This study integrates Zero Trust Architecture (ZTA) and Blockchain to strengthen cloud computing security. In the digital era, cloud computing has become a mainstream technology for data storage and processing globally. However, traditional perimeter-based security models have proven ineffective in dealing with modern threats, such as insider threats increasing by 60% and ransomware attacks on major cloud computing providers in 2022 resulting in billions of dollars in losses, highlighting the weaknesses of existing security models. Zero Trust Architecture (ZTA) offers a solution with a granular access control approach and layered authentication, but its implementation still faces challenges in efficiency and scalability, Blockchain, with its decentralized technology and immutable records, improves data transparency and integrity, but its use is often constrained by high energy consumption and latency. This study aims to explore between ZTA and Blockchain as innovative solutions to improve cloud security. By combining ZTA-based access control and Blockchain transparency, this study develops a security model that is resilient to both internal and external threats. Simulations show that ZTA and Blockchain integrity can reduce insider threats by 35% and increase data audit efficiency by 20%. This approach not only offers stronger protection but also provides an adaptive and transparent system for rapidly evolving cloud infrastructure.

Abstract

Keamanan jaringan nirkabel menjadi perhatian kritis seiring meningkatnya penggunaan Wireless Local-Area Network (WLAN) diberbagai sektor. Penelitian ini mengevaluasi efektivitas protokol keamanan WPA2-PSK dan WPA3-SAE dalam mencegah serangan deauthentication dan brute-force menggunakan Aircrack-ng suite. Metodologi penelitian menggunakan pendekatan penetration testing etis dalam lingkungan lab terkontrol dengan dua access point yang di konfigurasi menggunakan protokol WPA2-PSK dan WPA3-SAE. Pengujian dilakukan menggunakan Kali Linux 2024.4 dengan Aircrack-ng suite versi 1.7 dan adapter TP-LINK WN722n yang mendukung monitor mode. Hasil penelitian menunjukkan bahwa WPA2-PSK sangat rentan terhadap serangan deauthentication, dimana frame deauthentication palsu berhasil memutuskan koneksi klien dari access point. Analisis Wireshark mengonfirmasi keberhasilan injeksi paket deauthentication tanpa verifikasi yang memadai. Setelah handshake berhasil ditangkap, proses brute-force menggunakan wordlist 300.000 kata dapat dieksekusi dalam waktu 2 menit 21 detik. Sebaliknya, WPA3-SAE menunjukkan ketahanan signifikan terhadap kedua jenis serangan berkat implemetasi Protected Management Frames (PMF) yang menolak frame deauthentication palsu dan mekanisme simultaneous authentication of equals (SAE) yang mengeliminasi kerentanan terhadap offline dictionary attack. Penelitian ini membuktikan bahwa WPA3-SAE memberikan peningkatan keamanan substansial dibandingkan WPA2-PSK, dengan rekomendasi migrasi segera ke WPA3 untuk organisasi yang mengutamakan keamanan jaringan nirkabel.

Abstract

Abstrak - Dalam jurnal ini, para penulis akan mengkaji bagaimana Roblox, sebuah platform pengembangan permainan edukatif berbasis cloud computing, dapat diterapkan dalam praktik. Pengembangan permainan edukatif secara tradisional biasanya dibatasi oleh biaya infrastruktur server dan kompleksitas teknis. Roblox menyediakan model Platform as a Service (PaaS) sebagai salah satu solusi untuk memisahkan distribusi konten dan lingkungan pengembangan (Roblox Studio). Jurnal ini akan menganalisis arsitektur, kemampuan, dan dampak integrasi Roblox dalam pembelajaran menggunakan pendekatan studi literatur dengan pendekatan deskriptif terhadap berbagai artikel relevan. Temuan analisis menunjukkan bahwa arsitektur cloud di Roblox memungkinkan instruktur untuk mengembangkan kelas interaktif 3D tanpa perlu memelihara server hardware. Platform ini telah terbukti efektif dalam meningkatkan motivasi intrinsik siswa, serta hasil belajar mereka di berbagai disiplin ilmu, termasuk teknik otomotif dan literasi. Namun, penggunaannya terkait dengan masalah besar terkait keamanan siber, seperti ancaman perundungan siber, grooming, dan aspek moral komodifikasi pengguna (playbour). Disimpulkan bahwa meskipun Roblox memiliki potensi besar untuk mendemokratisasi pengembangan media pembelajaran modern, penggunaannya mutlak memerlukan pengawasan ketat dan strategi mitigasi risiko yang komprehensif.Kata kunci : Roblox; Game Edukasi; Cloud Computing; Game-Based Learning; Platform as a Service; Abstract - In this journal, the authors will examine how Roblox, a cloud computing-based educational game development platform, can be applied in practice. Diagnosis Educational game development traditionally has been constrained by the costs of server infrastructure and the complexity of the game.. Roblox provides a Platform as a Service (PaaS) model as a solution to separate content distribution and the development environment (Roblox Studio). This journal will analyze the architecture, capabilities, and impact of Roblox integration in learning using a literature study approach with a descriptive approach to various relevant articles. The findings of the analysis show that the cloud architecture in Roblox allows instructors to develop interactive 3D classes without the need to maintain hardware servers. This platform has been tested to be useful in enhancing the intrinsic motivation of students and their learning outcomes in other subjects, such as automotive engineering and literacy. However, its use is associated with major cybersecurity issues, such as cyberbullying, grooming, and the moral aspects of user commodification (playbour). It is concluded that despite having enormous potential of democratizing the development of modern learning media, the usage of Roblox must be strictly supervised and the process of implementing its usage should be accompanied by the extensive risk mitigation strategies.Keywords: Roblox; Educational Games; Cloud Computing; Game-Based Learning; Platform as a Service;

Abstract

As the number of users and digital activities increases, the need for quality internet networks in boarding houses is also increasing. However, Wi-Fi networks in boarding houses face challenges in the form of multi-story buildings with concrete walls, long corridors, and many small rooms, coupled with the high number of connected devices and differences in the characteristics of the 2.4 GHz and 5 GHz frequencies, which cause dead spots, decreased throughput, and increased delay during peak hours. This study uses a Systematic Literature Review method on 15 studies related to indoor Wi-Fi network design, bandwidth management, and Quality of Service analysis in boarding house environments. The results of the study show that the most suitable topology is the application of several access points at the center of the building or main corridor, reinforced by APs or repeaters in areas with high physical barriers, designed using a Top Down Network Design (TDND) approach to align with the needs of residents and the characteristics of the space. From a management perspective, the combination of User Manager, CAPsMAN, and PCQ is effective for authentication, fair bandwidth distribution, and access point load balancing, thereby reducing misuse and preventing overload. Quality of Service parameters such as throughput, delay, jitter, and packet loss are used to compare network conditions before and after optimization, and various studies show that this combination of topology design and bandwidth management consistently improves speed, stability, and equitable Wi-Fi access for boarding house residents.

Abstract

WiFi connectivity is crucial in supporting academic activities on campus, but its signal quality is affected by distance, physical obstacles, and Non-Line of Sight (NLOS) conditions. This study uses a Systematic Literature Review method to examine the influence of distance and environmental factors on the strength and stability of WiFi signals in campus buildings. The findings indicate that increased distance and the presence of physical barriers reduce RSSI and Signal-to-Noise Ratio (SNR) values, which subsequently decreases throughput and increases delay. Channel interference also contributes to connection instability. Optimization strategies such as proper access point placement and frequency channel management are essential to maintain network quality and ensure Quality of Service (QoS). This study provides strong indications of the key factors that need consideration in managing campus WiFi networks to support user comfort and usage efficiency.
