Abstract

Website Praditainfo merupakan situs profil resmi Universitas Pradita yang dituntut memiliki kualitas tinggi dari segi fungsi, performa, dan kenyamanan pengguna. Penelitian ini bertujuan mengevaluasi kualitas website berdasarkan standar ISO 9126, yang mencakup enam aspek: functionality, reliability, usability, efficiency, maintainability, dan portability. Metode penelitian meliputi pengujian teknis menggunakan black-box testing, tools WAPT v10.0 untuk uji performa, analisis GTmetrix untuk evaluasi efisiensi, serta penyebaran kuesioner USE Questionnaire kepada pengguna. Hasil evaluasi menunjukkan bahwa aspek functionality berjalan optimal dengan seluruh 34 fungsi berfungsi baik tanpa kendala (skor 1,0). Reliability mencapai tingkat keberhasilan 99,2% dalam pengujian 10 virtual users selama 10 menit, melampaui standar Telcordia sebesar 95%. Usability memperoleh skor 0,8 yang menunjukkan kemudahan penggunaan dan pengalaman pengguna yang cukup baik. Namun, aspek efficiency masih tergolong rendah dengan nilai performa 40%, struktur 58%, LCP sebesar 7,3 detik, dan CLS sebesar 0,42, yang menunjukkan perlunya optimasi seperti kompresi aset, penyederhanaan rantai permintaan, dan penerapan lazy loading. Maintainability dinilai baik berkat penggunaan framework Laravel dengan arsitektur Model-View-Controller (MVC) yang mempermudah pengelolaan kode. Portability menunjukkan hasil baik dengan kompatibilitas tinggi pada berbagai perangkat desktop maupun mobile. Secara keseluruhan, website Praditainfo telah memenuhi sebagian besar standar ISO 9126, namun peningkatan pada aspek efficiency dan usability masih sangat diperlukan.

Abstract

The development of information technology requires the banking sector to implement measurable IT governance and information security to ensure operational reliability and customer data protection. However, many financial institutions, including Bank Maju, do not yet have a comprehensive picture of the maturity of IT governance and information security in an integrated manner. This study aims to evaluate the maturity of information technology governance using the COBIT 4.1 framework and to assess information security readiness using the KAMI Index version 5.0. This study uses a case study method with a descriptive qualitative approach through document analysis, observation, and assessment of IT processes in four COBIT 4.1 domains: Plan and Organize, Acquire and Implement, Deliver and Support, and Monitor and Evaluate, and five main areas of the KAMI Index. The evaluation results show that Bank Maju’s IT governance maturity level is 3.58, or Level 3 (Defined Process), indicating that the process has been documented but not consistently and measurably implemented. The KAMI Index assessment shows information security readiness is in the Sufficient/Moderate category, with major weaknesses in risk management, asset management, and personal data protection. These findings indicate that weaknesses in IT governance directly impact the low effectiveness of risk management and information security. This research contributes to this by providing an integrated evaluation approach that links IT governance and information security readiness as a basis for formulating improvement recommendations in the banking sector.
