Abstract

Penelitian ini menginvestigasi dampak edge caching terhadap reliabilitas pengiriman audio assessment online berskala kecil melalui perbandingan empat konfigurasi: Direct No-CDN, Direct CDN, HLS No-CDN, dan HLS CDN. Konteks ini mengevaluasi audio prerecorded berdurasi pendek (3–13 detik) pada jaringan mobile Indonesia dengan 235 pengguna riil menggunakan desain within-subjects dan analisis sensitivitas threshold Acceptable Delay (0 ms, 500 ms, 3000 ms). Hasil Cochran's Q menunjukkan efek signifikan konfigurasi terhadap reliabilitas (Q = 265,88, p < 0,001). CDN mengurangi tingkat gagal AD dari ~75–82% menjadi ~14–21% secara independen dari protokol. Uji Mann-Whitney U mengkonfirmasi tidak terdapat perbedaan signifikan pada median gagal AD antara Direct CDN dan HLS CDN pada threshold 500 ms (p = 0,706, median keduanya 0%). Temuan ini menyanggah stereotip bahwa HLS kurang cocok untuk konten berdurasi pendek dan mengidentifikasi edge caching sebagai determinan utama reliabilitas, menggeser prioritas dari pilihan protokol ke implementasi CDN.

Abstract

The “AntriSmecone” queuing system was implemented in the PPDB process at SMK Negeri 1 Purwokerto to improve efficiency by up to 70%. However, the system encountered several issues, such as race condition conflicts in queue numbers and code execution errors caused by automatic translation. This study employs the IT-IL V3 framework, focusing on the Service Operation domain to analyze IT service management, particularly in the subdomains of incident management and request fulfillment. The research methodology includes interviews, observations, questionnaire distribution, and literature studies. The analysis results indicate that the system's maturity level is at level 4 (Managed and Measurable), with an average score of 3.74. The system has structured and monitored procedures, allowing deviations to be effectively addressed. Recommendations were formulated to optimize incident management and fulfill user requests. This study contributes to the development of the “AntriSmecone” system to ensure service quality and efficiency in the PPDB process.
