Pendekatan HCI dalam Evaluasi dan Redesain Aplikasi Jaklitera untuk Peningkatan UX

The Jaklitera application is a digital platform aimed at supporting literacy among Jakarta residents through features such as digital book collections, online borrowing, and literacy-related information. However, the application faces challenges in usability, including unintuitive navigation, inconsistent design, and a lack of clear user guidance. This study evaluates and improves the quality of the user interface (UI) and user experience (UX) of the Jaklitera application using a Human-Computer Interaction (HCI) approach. Methods employed include heuristic evaluation based on Nielsen’s 10 principles, interviews with active users, interface redesign using Figma, and measuring user satisfaction through the System Usability Scale (SUS). The research aimed to identify usability issues that hinder user engagement and propose targeted solutions through iterative design improvements. The redesign process addressed critical areas, including reorganizing the navigation menu, improving visual layouts for clarity, and introducing onboarding features to guide new users. Efforts were also made to enhance the application’s accessibility, ensuring inclusivity for a broader range of users, including those with limited digital literacy. User interviews provided insights into expectations, highlighting that aesthetics, functionality, and ease of access were top priorities for improving the user experience. After implementing the HCI-based redesign, the SUS score increased significantly to 84.64, indicating improvements in efficiency, effectiveness, and user satisfaction. This study demonstrates how applying HCI principles can lead to more user-centered digital platforms, encouraging sustainable usage and fostering literacy among the community. The findings and redesign process offer insights for developing more inclusive, user-friendly digital literacy applications.
