Resvi Chandra Septia Syaharani Universitas Lampung Indonesia , Anabella Thalety Rizky Universitas Lampung Indonesia , Esmoyojati Universitas Lampung Indonesia , Anjas Darmansyah Universitas Lampung IndonesiaThe rapid transition to online learning has led students to depend heavily on smartphones for accessing video conferencing platforms such as Zoom Cloud Meeting, mainly because of limited laptop availability. Nevertheless, the mobile interface introduces various technical and ergonomic issues that lead to low user interface comfort and high cognitive workload during online learning. This study examines the usability and mental workload associated with the Zoom mobile application during online classes using the System Usability Scale (SUS) and NASA-Task Load Index (NASA-TLX). Data were obtained through a Google Forms survey involving 36 respondents, consisting of university and school students. The findings revealed an average SUS score of 59.09, which falls below the accepted usability benchmark, indicating poor usability and low interface comfort. In addition, the NASA-TLX analysis produced an average Weighted Workload (WWL) score of 67.46, showing that most participants experienced a substantial mental workload primarily driven by the mental demand dimension. Practically, these findings imply an urgent need for mobile interface optimization and highly recommend using larger-screen devices like laptops for synchronous classes to minimize cognitive fatigue

Az Zahra Putri Aulia Program Studi Pendidikan Teknologi Informasi, Universitas Lampung Indonesia , Berliantina Julia Putri Universitas Lampung, Program Studi Pendidikan Teknologi Informasi Indonesia , Tegar Pujiono Program Studi Pendidikan Teknologi Informasi, Universitas Lampung IndonesiaThis study aims to analyze the usability of TikTok Shop and its impact on users' online shopping experience by applying Nielsen's five usability attributes: Learnability, Efficiency, Memorability, Error Handling, and Satisfaction. A mixed-methods approach was employed, integrating task-based usability testing, structured observation, and in-depth interviews with ten active TikTok Shop users aged 18–35 years, who were selected through purposive sampling. The System Usability Scale (SUS) served as the primary quantitative instrument for evaluating overall usability. The findings indicate a mean SUS score of 76.5, placing TikTok Shop within the "Good" usability category (Grade B). The platform demonstrated strong performance in the Learnability and Satisfaction dimensions, largely due to its interactive video-based interface, which facilitates user engagement and ease of use. However, notable cognitive friction was identified in the Efficiency and Error Handling dimensions. The average checkout completion time was 4 minutes and 37 seconds, primarily resulting from complex navigation and the presence of non-specific error messages during the transaction process. Based on these findings, the study recommends streamlining the checkout workflow to a maximum of three steps and implementing contextual, informative error feedback to improve transaction efficiency and overall user experience.

Nadia Valentina Universitas Lampung Indonesia , Nofa Ariko Aldiyansyah Universitas Lampung Indonesia , Antika Maharani Universitas Lampung Indonesia , Novita Rahayu Universitas Lampung IndonesiaThe rapid growth of social media has transformed information-searching behavior, particularly among Generation Z, who increasingly use TikTok and Instagram as social search engines. This study aims to analyze Generation Z's perceptions of perceived usefulness, perceived ease of use, trust, and user decision regarding the use of TikTok and Instagram as social search engines. A quantitative descriptive survey approach was employed by distributing a five-point Likert-scale questionnaire to 106 Generation Z respondents who had used the search features on TikTok or Instagram. Descriptive analysis revealed that perceived usefulness achieved the highest mean score (4.24), followed by user decision (4.11), perceived ease of use (4.06), and trust (4.04). These findings indicate that respondents have positive perceptions of using TikTok and Instagram to search for visual information, particularly related to culinary, tourism, products, entertainment, and lifestyle. The findings provide insights into the changing information-searching behavior of Generation Z and may serve as input for social media platform developers to design search systems that are visually engaging, easy to use, and supportive of users' information validation processes.

Fauzan Raditiya Universitas Lampung Indonesia , Tyas Syafa Pratiwi Universitas Lampung Indonesia , Larasati Universitas Lampung Indonesia , Muhammad Aditya Rahman Universitas Lampung IndonesiaThe development of educational technology (edtech) has increased the use of digital learning applications, especially by Generation Z who grew up as digital natives with high expectations for responsive and intuitive interfaces. Many edtech applications have not been able to provide a user experience (UX) that aligns with mental models, users’ cognitive representations of how systems work, potentially triggering technology rejection. This study aims to analyze the mental model characteristics of Generation Z toward digital learning applications, identify the UX factors that most influence their acceptance, and explain the relationship between interface design and Generation Z preferences. A systematic literature review (SLR) method following PRISMA guidelines was used, analyzing 11 sources from Google Scholar, IEEE Xplore, and Semantic Scholar published between 2015–2024. Results show that Generation Z’s mental models are shaped by social media interaction habits, leading them to reject applications with complex navigation and slow responses, while accepting minimalist design, instant feedback, and personalization. Unlike previous UX reviews that focus on general usability, this study specifically synthesizes the intersection of generational cognitive characteristics and edtech interface design, offering a novel analytical framework that links mental model theory with Generation Z’s behavioral tendencies. The practical contribution of this study lies in providing evidence-based design guidelines for edtech developers to align interface architecture with the cognitive expectations of Generation Z users, ultimately supporting higher adoption rates and reduced technology rejection in digital learning environments.

Asifa Dwi Lestari Universitas Lampung Indonesia , Doris Olga Ulimaz Alzena Universitas Lampung Indonesia , Maulia Fitri Universitas Lampung IndonesiaMobile application development demands interfaces that are usable and user-friendly, making usability evaluation at the prototype stage essential. This literature review, rather than an empirical study involving direct user testing, examines usability evaluation techniques (including observation, interviews, questionnaires, System Usability Scale, User Experience Questionnaire, and heuristic evaluation) applied to mobile application prototypes. Searches were conducted through Google Scholar, ResearchGate, and accredited national journal portals covering 2025–2026, yielding 15 articles of which 12 were analyzed. This study aims to identify the strengths and limitations of each technique and their suitability for various scenarios. Findings show each technique offers distinct advantages: the System Usability Scale is practical and sensitive to design changes, the User Experience Questionnaire captures multidimensional user experience, and heuristic evaluation enables expert-based inspection without user involvement. Combining multiple techniques yields more comprehensive results. Technique selection should be aligned with evaluation objectives, available resources, and the stage of application development.
Pages: 32-39Views: 30 Downloads: 13Analisis Antarmuka VClass Universitas Lampung: Evaluasi Prinsip Heuristik dan Eksplorasi Kebutuhan Sistem Pengingat Batas Waktu Tugas
Kahfi Asafa Pendidikan Teknologi Informasi, Universitas Lampung Indonesia , Eka Dyta Sari Pendidikan Teknologi Informasi, Universitas Lampung Indonesia , Reza Prawira Adijaya Pendidikan Teknologi Informasi, Universitas Lampung Indonesia , Raisya Putri Rahayu Pendidikan Teknologi Informasi, Universitas Lampung IndonesiaThis study examines the VClass interface of the University of Lampung from two interrelated perspectives: first, evaluating the suitability of the interface design with the principle of system status visibility (one of Nielsen's 10 heuristic principles); second, exploring and formulating the features needed for an effective assignment deadline reminder system. The background of the study stems from the phenomenon where 45% of students admitted to being "sometimes" late in submitting assignments, while 40% stated "rarely," indicating that the problem of lateness is not caused by pure negligence, but by deficiencies in information design on the platform. The study used a descriptive quantitative approach with a questionnaire instrument based on a Likert scale of 1–5 distributed to 20 Information Technology Education students of the Faculty of Teacher Training and Education, University of Lampung. The results of the heuristic evaluation showed that the average system visibility score only reached 3.43 out of 5.00 (moderate category), with critical points being the deadline list feature on the main page (M=2.90) and the clarity of the deadline under the assignment title (M=3.00). The needs analysis revealed that respondents strongly needed automatic H-3/H-1/H-0 notifications (M=4.16), a centralized widget across courses (M=4.10), and general system improvements (M=4.30). The contribution of this research is a structured needs analysis document that can be a reference for developers in redesigning the VClass deadline reminder system to be more proactive, contextual, and integrated.
