Abstract

Consideration of people, problems, and context is part of the design thinking approach to problem solving. Redefining complicated problems effectively can benefit greatly from this method. Specifically in this study, the development of the nutrition fulfillment application program for autistic children. The calculation of the percentage of test participants who successfully completed the task was 94.3%. The prototype provides high effectiveness based on the assigned task related to the daily diet food menus for autism. The results of the evaluation of the efficiency aspect present a value of 0.085 goals/sec which means that test participants completed 1 task in about 11.76 seconds and is more efficient than the manual process. The result of satisfaction evaluation based on SUS shows that average of the result of the questionnaire is 72 from 100 means that the user easily operates the prototype.

Abstract

Some boarding schools prohibit the use of gadgets in daily life. Prohibition of the use of gadgets makes students unable to keep up with the development of existing information technology, so it can affect the ability of students to operate information technology related to their utilization of information technology. Students feel dissatisfied with their gadgets because they feel left too far behind with existing technological developments. This dissatisfaction affects individual motivation to accept the development of information technology, causing discomfort, stress, and even fear when dealing with information technology. The rapid growth of technology, but the lack of access for students, can lead to technostress. Technostress has five components: techno-overload, techno-invasion, techno-complexity, techno-insecurity, and techno-uncertainty. This study aims to determine the effect of limiting gadget use on technostress, which affects students' academic performance and life satisfaction. Statistical analysis using PLS-SEM was conducted in this study. Statistical results show that restrictions on gadget use can cause techno-complexity (51.7%) and techno-insecurity (14.5%) in students. However, techno-complexity and techno-insecurity do not affect students' academic performance. On the other hand, techno-insecurity affects the decrease in students' life satisfaction (21.7%) and academic performance (14.1%). Techno-uncertainty affects the reduction of students' academic performance (10.9%).

Abstract

Web application performance has emerged as a critical determinant of digital business success, where load time reductions demonstrably correlate with user conversion rates. Nevertheless, the prevalence of JavaScript frameworks in contemporary development landscapes introduces a fundamental trade-off between developmental convenience and inherent performance overhead. This challenge is compounded by the divergent architectural paradigms adopted by frameworks, distinguishing between Virtual DOM (VDOM) and compile-time approaches. While optimization techniques exist, the question remains whether their efficacy is universal or moderated by framework architectural characteristics. This study analyzes the interaction effects between these two factors on user-centric performance metrics through a two-way factorial experimental design, developing two identical news portal websites using VDOM and compile-time frameworks. Five optimization strategies were implemented sequentially as experimental scenarios. Statistical analysis employed Aligned Rank Transform (ART) ANOVA and ART-C post-hoc testing on FCP, LCP, and TBT metrics. Findings indicate a consistent superiority of compile-time architecture over VDOM in FCP (p-value < 0,05), absent statistically significant optimization strategy influence (p-value > 0,05). Conversely, significant interaction effects emerged within LCP and TBT metrics (p-value < 0,05). The research concludes that optimization strategy effectiveness regarding LCP and TBT is contextual, contingent upon the architectural characteristics of the framework employed
