EVALUATION AND IMPROVEMENT OF INTERFACE DESIGN OF SI KROMO PAGE USING USER CENTREED DESIGN APPROACH

Introduction

Evaluation and improvement of interface design of si kromo page using user centreed design approach. Evaluasi dan perbaikan desain antarmuka website pembelajaran Si Kromo menggunakan User Centered Design (UCD). Meningkatkan usability dari skor SUS 54,75 menjadi 80,15.

Abstract

Website Si Kromo adalah salah satu website pembelajaran bahasa Jawa Krama dengan alamat website yaitu www.sikromo.com. Sejak diresmikan pada tahun 2021, pengguna Si Kromo pada tahun pertama terbukti meningkat, namun pada tahun kedua yakni 2022 pengunjung mulai menurun. Maka dari hal tersebut, peneliti melakukan evaluasi desain dan merancang ulang antarmuka beberapa halaman pada website Si Kromo. Penelitian ini bertujuan untuk mengetahui tingkat usability website Si Kromo. Proses evaluasi dan perbaikan desain website Si Kromo menggunakan metode pendekatan User Centered Design (UCD) dengan pengambilan data responden menggunakan System Usability Scale (SUS) dan Usability Testing. Kuesioner evaluasi dibagikan sebanyak dua kali, yaitu evaluasi pertama pada desain lama website Si Kromo dan evaluasi kedua pada desain baru Si Kromo. Responden yang digunakan dalam penelitian ini sebanyak 50 responden yang sama baik evaluasi pertama maupun evaluasi kedua. Penelitian ini menghasilkan skor SUS evaluasi pertama sebesar 54,75 dan skor SUS evaluasi kedua sebesar 80,15 dengan peningkatan skor SUS yakni 25,4. Pengujian lain dengan Performance Measurement menghasilkan nilai Effectiveness Completion Rate sebesar 94.8%. Sedangkan rerata waktu responden dalam menyelesaikan task antara 1-10 detik dan mendapatkan temuan permasalahan pada task 2, task 9, dan task 10. Pada analisis hipotesis, hasil yang diperoleh dari uji tersebut yaitu hipotesis H0 ditolak dan H1 diterima yang menandakan bahwa hasil skor rata-rata usability website Si Kromo tidak sama dengan 68 yaitu lebih besar dengan nilai skor sebesar 80,15.

Review

This paper presents a focused evaluation and improvement initiative for the Si Kromo website, an online platform dedicated to learning the Javanese Krama language. The motivation for this study is clearly articulated: despite initial growth following its 2021 launch, the website experienced a concerning decline in user engagement during its second year. Recognizing this critical issue, the researchers aimed to assess the current usability of the Si Kromo website and subsequently redesign its interface to enhance the user experience. This objective is highly relevant, addressing a common challenge faced by digital platforms in retaining user interest and effectiveness. The methodology employed is robust, centered around a User-Centered Design (UCD) approach, which is appropriate for interface improvement studies. Data collection relied on two well-established methods: the System Usability Scale (SUS) for quantitative usability assessment and Usability Testing to uncover specific interaction issues. A commendable aspect of the study design is the use of the same 50 respondents for both the initial evaluation of the old design and the subsequent evaluation of the redesigned interface, ensuring consistent feedback. Beyond SUS, the study also incorporated Performance Measurement, including Effectiveness Completion Rate and average task completion times, to provide a more holistic view of usability, complemented by hypothesis testing to statistically validate the improvements. The results strongly support the effectiveness of the redesign effort. The initial SUS score for the old design was a concerning 54.75, indicating poor usability. Following the UCD-driven improvements, the SUS score significantly rose to 80.15, marking an impressive increase of 25.4 points. This final score, being well above the industry average benchmark of 68, confirms a substantial enhancement in usability. Further analysis from Usability Testing revealed a high Effectiveness Completion Rate of 94.8% and identified specific problem areas in tasks 2, 9, and 10, despite generally quick task completion times. The statistical rejection of H0 and acceptance of H1 further solidifies the conclusion that the improved design led to a statistically significant increase in the website's average usability score, providing clear evidence of the project's success in addressing the initial decline in user engagement.
