This study evaluated the effectiveness of the JKN Mobile interface using Nielsen’s Usability Heuristic Principles to identify issues that affect clarity, consistency, and user navigation. The research applied a descriptive qualitative approach through interface observation and visual analysis, focusing on typography, layout, color usage, iconography, and feedback mechanisms. The findings showed that several essential elements of system status were not clearly presented, such as loading indicators, data update information, and synchronization cues. Inconsistencies in icon style, visual hierarchy, and button functions further reduced predictability and increased the cognitive load on users. Some screens also displayed incomplete content and unclear action mapping, which disrupted task flow. The study concludes that improving visual hierarchy, standardizing interface components, refining navigation paths, and providing clearer feedback can strengthen usability and support the application’s role as an accessible digital public service.

The effectiveness of a retail store layout plays a crucial role in supporting operational efficiency, service flow, and customer experience. Brother Parfume, a perfume refill retail store, currently applies a bar-service layout designed based on intuition and daily operational needs rather than systematic planning. This often results in inefficient movement patterns, limited space utilization, and suboptimal coordination among functional areas. This study aims to redesign the store layout by applying the Entity Relationship Chart (ERC) and Total Closeness Rating (TCR) methods to identify functional relationships and determine the ideal spatial arrangement. Data were collected through direct observation and semi-structured interviews with the store owner to understand the interaction between service areas, product displays, and storage sections. The ERC analysis shows that the service area, perfume display, and bottle display have the highest functional interdependence, while the storage area has the lowest necessity for proximity. TCR results confirm these findings, with the service area and perfume display each scoring 90, bottle display 21, and storage 3. Based on these results, two alternative layouts are proposed that integrate high-priority areas into a unified service zone and position storage separately to minimize unnecessary movement. The redesigned layout is expected to enhance service speed, optimize space utilization, support operational procedures, and strengthen the store’s servicescape. This research contributes practical insights into the application of ERC and TCR methods for small-scale retail operations, particularly in the perfume refill sector, where service efficiency and spatial constraints are critical.

Museums are essential for preserving culture and history, especially in cities like Jakarta, which have a history that spans from prehistoric times to modern times. The Fatahillah Museum in Jakarta is the best place to learn history because it has a collection of artifacts, important documents, and thematic exhibitions. The museum is not only a center for education, but it also helps to promote local culture through various activities such as workshops and seminars. The main challenge to improving the visitor experience is poor layout and circulation of the space. The way visitors enjoy the collections on display in the museum is greatly influenced by the layout, including the way the space is arranged. The Fatahillah Museum uses a hub-and-spoke and linear layout to direct visitors in a systematic way. But there are some problems, such as limited space, unergonomic collections and a poor navigation system. The space is filled with unique but sometimes confusing vertical and horizontal circulation grooves due to the architectural style of colonial Dutch museums. Factors such as visibility, lighting, and ergonomics also play a role in improving visitor comfort. With over 615,000 visitors in 2023, this problem is becoming more apparent, especially during busy holidays. To address this, the layout must be optimized, modern navigation is used, and the design of the exhibition hall must be updated to become more interactive and help students learn. In addition, arranging the collection chronologically and thematically can help visitors understand the historical and cultural context of the museum's collections.

This study aims to analyze the effect of store layout and product display on computer spare part sales at Bandung Trade Mall. The background of this study is based on the increasing competition in the computer retail business, which requires effective visual merchandising strategies to attract consumers. The research method used a quantitative approach with a survey of 20 respondents selected purposively. Data were collected through questionnaires, observations, and informal interviews, then analyzed using multiple linear regression. The results show that store layout and product display have a significant simultaneous effect on sales with an F value of 12.43; sig. < 0.05. The coefficient of determination (R²) of 0.62 indicates that both variables explain 62% of the variation in sales, while the rest is influenced by other factors outside the model. These findings reinforce the S-O-R theory that visual stimuli can increase consumer comfort, interest, and impulse buying. This study has practical implications for computer retailers to optimize store layout and product display as a strategy to improve sales performance.

Human Resource Management (HRM) is a very important part of an organization. In the digital era, HRM can be done more efficiently through mobile applications that allow access to employee data, HRM processes, or online attendance. However, the ability of an HRM mobile application to succeed depends on the usability factor or ease of use by users.  Talenta is one of Mekari's business platforms that provides a complete solution for all Human Resources (HR) and payroll management issues. Talenta is an application that will be used for Usability Testing using Cognitive Walkthrough. The initial stage in starting Usability Testing on the mobile-based Talenta application with the Cognitive Walkthrough method begins with conducting a literature study, learning the system or application, then making scenario questions based on the system. Then, respondents will be asked to complete the scenario questions. The scenario data collected includes; data on success in completing the scenario, data on errors in completing the scenario, and data on the time required to complete the scenario. Finally, the interview stage will be continued with the respondents on the scenarios that have been carried out. The scenario and interview data will be analyzed to calculate the effectiveness and efficiency aspects of the Talenta application. After the analysis stage, users will be given a System Usability Scale (SUS) questionnaire to be answered using Google Form using a Likert scale. The results of the questionnaire will be analyzed using SUS calculations, and then suggestions and conclusions will be given in the aspect of user learning ability. After usability testing of Talenta mobile application using Cognitive Walkthrough and SUS methods, the following results were obtained: 78% effectiveness; 0.10 seconds efficiency; and 67 learning ability level. Talenta has met the usability criteria for mobile applications in general, including effectiveness and efficiency in using the ISO 9241-11 model. However, there are still shortcomings in the user learnability level. To improve the usability of this application, it is recommended to change the layout, menu, add features, as well as clarify some display features.
