Abstract

Kitab suci Al-Qur'an terdiri dari 114 surah dengan 6236 ayat yang dijadikan sebagai sumber ajaran dan pedoman untuk umat muslim di seluruh dunia. Semua ayat di dalam Al-Qur’an memiliki keterkaitan satu sama lain yang tersusun secara hierarki yaitu dalam sebuah surah terdiri dari nomor surah dan nama surah, kemudian setiap surah tersebut memiliki banyak ayat. Untuk melihat keterkaitan antar ayat dalam Al-Qur’an tersebut Penyimpanan data secara hierarki pada database relasional membutuhkan lebih banyak tabel dan terlalu banyak join tabel yang dilakukan yang membuat kinerja temu balik informasi menjadi lebih lambat. Oleh karena itu dibutuhkan graph database yang dapat menangani permasalahan tersebut yang mampu menyimpan data hierarki lebih efisien. Selain itu, graph database dapat membantu visualisasi keterkaitan antar ayat di dalam Al-Qur’an. Hasil penelitian ini menunjukkan bahwa graph database sebagai basis data non-relasional mampu menyimpan data hierarki Al-Qur’an dalam bentuk graf yang terdiri dari nodes untuk merepresentasikan surah dan ayat dan edges untuk merepresentasikan relasi atau hubungan antara surah dengan ayat. Hasil lainnya bahwa graph database mampu memvisualisasikan keterkaitan antar surah dengan ayat dengan lebih efisien tanpa membutuhkan kueri data dengan join tabel yang rumit.

Abstract

Website English Proficiency Test (EPT), which functions as a registration system for student English proficiency tests, still exhibits several UI and UX issues, including unclear navigation flow, inconsistent visual design, limited information accessibility, and inefficient interaction processes. These limitations negatively affect usability, user satisfaction, and the overall effectiveness of the system. This study aims to improve the User Interface (UI) and User Experience (UX) of the EPT website by applying the Human-Centered Design (HCD) approach combined with the User Experience Questionnaire (UEQ) as an evaluation tool. The study involved 100 respondents selected using purposive sampling, with data collected through interviews and UEQ questionnaires, and analyzed using mean comparison and UEQ benchmark analysis. The results show significant improvements across all UEQ dimensions, namely Attractiveness (0.64 to 1.60), Perspicuity (0.77 to 1.85), Efficiency (0.81 to 1.65), Dependability (0.86 to 1.75), Stimulation (0.43 to 1.75), and Novelty (0.16 to 1.65), with most dimensions falling into the Good to Excellent categories. These findings indicate that the redesigned interface significantly enhances usability, efficiency, and visual appeal. The novelty of this study lies in the integration of the HCD approach with UEQ-based evaluation using a before-and-after (as-is vs to-be) comparison framework. The implications of this study suggest that user-centered design approaches can be systematically applied to improve digital service quality, increase user satisfaction, and support more efficient academic service systems.
