Abstract

Self-service has been widely adopted by various companies worldwide for different purposes; for example, in customer service settings, it automates repetitive and simpler tasks handled by agents. However, self-service systems for resolving customer issues have limitations. This study thus aims to evaluate the usability of the self-service system on the help center of an e-commerce app. Usability evaluation was conducted using both qualitative and quantitative methods. Quantitative data were collected through a survey with demographic and introductory questions, the System Usability Scale (SUS) questionnaire, and follow-up questions. In total, 200 responses were collected (195 of which were valid). Since the average SUS score was 67.35, the data analysis revealed that the self-service system has usability issues, particularly in learnability and efficiency. Additionally, usability testing and in-depth interviews were conducted with 12 participants to collect qualitative data to be analyzed using thematic analysis. Based on these findings, the study concludes that the development team can prepare a plan to enhance the user interface of the self-service system on E-Commerce XYZ’s help center to enhance usability.

Abstract

In the digital era, the challenges faced by lecturers and students in learning are increasingly diverse, which makes students tend to be less involved in learning. A student response system called “K-Owl” is proposed to support the Know, Want to Know, Learn (KWL) strategy where lecturers can monitor students’ knowledge in real-time while the platform helps students stay actively engaged in class. User-Centered Design was used as a methodology to ensure that the proposed platform aligns with user needs, with stages including identifying user problems and needs, system design and development, and evaluation. This study involved 16 interview participants and 71 usability testing participants. Quantitative data were collected using the System Usability Scale (SUS) and the Maze application to usability testing and analysed using the SUS Score and Maze Score. Meanwhile, qualitative data were collected through user interviews and analysed using thematic analysis. This study resulted in three main features including courses management, KWL, and dashboard. The results of user acceptance testing and usability testing were with a score of 100% and a SUS score of 69 (Good category), respectively. The results of the study indicate that K-Owl is a promising platform to support active learning.

Abstract

The GoFood Merchant application serves as a critical platform for merchant onboarding and product activation within Indonesia’s digital food delivery ecosystem. Despite its key role, user feedback indicates persistent usability issues, particularly in corporate onboarding. This study evaluated and improved the usability of GoFood Merchant by focusing on workflow complexity, information clarity, and interface consistency. A mixed-methods exploratory case study was conducted involving quantitative and qualitative data collected from merchant owners, merchant staff, and IT experts. Quantitative data were obtained using the system usability scale (SUS) questionnaire, while qualitative data were collected through task-based usability testing, open-ended questions, and an evaluation based on heuristic design principles derived from Shneiderman’s eight golden rules of interface design. The initial evaluation of the existing (“as-is”) interface yielded an SUS score of 63.83, indicating usability below the accepted benchmark, and revealed 10 consensus usability issues related to complex task flow, unclear system feedback, and inconsistent interface elements. Based on these findings, a redesign was developed using user-centered design (UCD) principles through iterative low-fidelity and high-fidelity prototyping. The redesigned (“to-be”) prototype was subsequently evaluated using the same instruments. Usability was significantly improved, with an SUS score of 85 and average principle-based evaluation ratings above 4.0 across all interface design principles derived from Shneiderman’s eight golden rules. These findings demonstrate that systematic usability evaluation combined with iterative UCD-based redesign can effectively enhance user satisfaction, efficiency, and comprehension in complex onboarding systems. This study provides validated design recommendations for improving GoFood Merchant onboarding and contributes empirical evidence for usability-driven interface redesign in large-scale mobile platforms.

Abstract

This study focuses on evaluating and improving the usability of the XYZ Checkout System, which previously exhibited several issues that negatively affected transaction completion, including unclear information hierarchy, inconsistent interface behaviour, and inefficient checkout flows. To address these challenges, the research adopted a User-Centered Design (UCD) approach supported by a mixed-method evaluation strategy, combining the System Usability Scale (SUS), usability testing, and open-ended questions. A between-subject research design was employed, involving two independent groups of participants. The initial as-is evaluation was conducted with 35 users and produced an average SUS score of 69.57, indicating marginal usability and the presence of notable interaction barriers. Based on the findings, a high-fidelity to-be prototype was designed using established usability heuristics and UCD principles. The redesigned interface was subsequently evaluated by a different group of 35 users, resulting in a significantly improved average SUS score of 96.64, classified as Excellent with high acceptability. Overall, the results demonstrate that the proposed design improvements successfully enhanced interface consistency, clarity of interaction, and checkout efficiency, emphasizing the critical role of systematic usability evaluation in optimizing e-commerce checkout systems.

Abstract

The digital transformation of the insurance sector has necessitated mobile services with superior usability. The My Taspen Life mobile application has experienced low user satisfaction attributed to its suboptimal user interface (UI) and user experience (UX). This study aimed to evaluate the application's usability and propose a validated high-fidelity prototype employing a User-Centered Design (UCD) approach. A mixed-methods evaluation comprised a System Usability Scale (SUS) survey, a Cognitive Walkthrough with experts, and Usability Testing. The identified issues were mapped against Shneiderman’s Eight Golden Rules of Interface Design to develop an adequate solution. The initial results showed an average SUS score of 65.51, below the global SUS average, and identified critical constraints in layout, navigation, and visual representation. Following the redesign, the prototype was re-evaluated by 12 participants, equally distributed between employees and external users. The final evaluation demonstrated a significant improvement, achieving a SUS score of 83.54 (Grade A, "Excellent"). Task scenario testing further confirmed that the new interface significantly reduced user dissatisfaction. We conclude that implementing UCD-based intervention can address significant usability problems in e-insurance applications.

Abstract

The Bot Usability Scale (BUS-42) is a tool specifically designed to evaluate chatbot usability, yet it has not been extensively applied in Indonesian contexts. This study aimed to adapt the BUS for Indonesian users, following Beaton’s cross-cultural adaptation framework to ensure cultural and linguistic relevance. The Indonesian adaptation was tested with 103 participants from the Faculty of Computer Science at one of large public universities in Indonesia, resulting in a high Cronbach’s Alpha of 0.922, confirming strong internal consistency. The adapted BUS-42 covers various usability attributes, including ease of use, accessibility, and response speed, making it suitable for assessing chatbot usability in academic settings. Findings suggest that the Indonesian-adapted BUS-42 is a reliable and comprehensive tool, applicable to different domains beyond education, such as e-commerce and government services. Future research should focus on extending BUS-42 testing to diverse chatbot applications and performing validity and sensitivity analyses to optimize its utility across various Indonesian user contexts.
