Abstract

The rapid growth of digital logistics has increased dependence on mobile delivery applications to manage shipments, package information, and courier operations under strict time constraints. Nowdays, ergonomic and usable user interface design is essential to reduce cognitive load, minimize errors, and maintain operational efficiency. However, empirical usability research focusing specifically on delivery service applications remains limited, particularly studies conducted in realistic usage contexts. This study evaluates the ergonomic quality of a mobile delivery application using online usability testing. A quantitative evaluation framework is applied, employing three established metrics: the System Usability Scale (SUS), task completion time, and error rate. These measures capture perceived usability, interaction efficiency, and error occurrence during representative delivery-related tasks. The findings reveal key usability issues related to navigation structure, information presentation, and interaction flow that negatively affect user performance. The result, study proposes data-driven UI design improvements aimed at enhancing clarity, efficiency, and cognitive ergonomics. The novelty is its integration of online usability testing with ergonomic evaluation in the delivery application domain, an area that remains underrepresented in recent human–computer interaction research. The outcomes provide scalable evaluation benchmarks and practical design guidance to support the development of more efficient, user-friendly, and ergonomically appropriate mobile delivery applications.

Abstract

Abstract— Low reading interest in Indonesia (0.001%) demands innovation in digital literacy applications like Bacana. However, Bacana's current interface remains conventional, potentially limiting user satisfaction. This study aims to evaluate the implementation of the Super Golden Ratio (ψ≈1.4656) and horizontal scrolling navigation to enhance aesthetics and user experience. The research method involved instrument testing with high reliability (Cronbach’s α>0.94) and linear regression analysis. The results indicate that all regression assumptions were met, showing no heteroscedasticity or autocorrelation, with a significant linear relationship (p<0.001). Empirical findings prove that the combination of the Super Golden Ratio and horizontal scrolling effectively improves readability, interaction smoothness, and user satisfaction. This study provides a strategic contribution to UI/UX development for literacy applications by utilizing mathematical ratios to achieve better visual harmony and navigational efficiency.
