Abstract

Just Meme is a mobile application used for expressing people's feelings by creating stickers, GIFs, and funny videos. The aim of this research is to evaluate the user interface of the Just Meme application using the Heuristic Evaluation Method. Prior to this study, the researcher conducted an evaluation with 20 users of the Just Meme application, resulting in a plethora of user comments. Consequently, the researcher decided to assess the quality of the user interface in the Just Meme application with the goal of ensuring user satisfaction with the new feature displays and attracting more users to use this application. This was accomplished by distributing questionnaires to individuals considered experts in the field. The research findings, based on the ten principles of Heuristic Evaluation, revealed two principles with significantly higher scores than the others. Firstly, "recognition rather than recall" received a total score of 1.444 (cosmetic problem), indicating no need for improvement as it does not affect the user. Secondly, "Help and Documentation" scored similarly, with a total of 1.333 (cosmetic problem), suggesting that no significant improvements are required, and it does not impact the user

Abstract

Saheb is a web-based pet shop application built with Next.js and Firebase, offering pet product sales and online veterinary consultation services. However, Saheb faces challenges in integrating with third-party applications and system efficiency due to its reliance on Firebase. This study aims to design a REST API using Express.js to enhance modularity, integration, and application performance. The research methodology includes literature review, REST API design using layered architecture principles, and JWT authentication implementation. Evaluation shows that the REST API implementation reduced Firebase resource usage by 57.66% and significantly improved website performance, with average reductions in Speed Index, TBT, and LCP times. The integration of the REST API with third-party applications successfully facilitates interaction without direct Firebase connections. The study concludes that the implementation of REST API improves the efficiency, scalability, and performance of the Saheb application, and opens up opportunities for further development.

Abstract

This research aims to design an optimal user interface and user experience for language learning applications with the Mobile-First Design approach with the Goal-Directed Design method, which focuses on user goals. User needs analysis was conducted through questionnaires, surveys, and observations to develop usage scenarios. UI design focused on clarity, intuitive navigation, and simple layout, as well as visual appeal. At the UX stage, responsive design principles and user experience testing were applied to ensure that the app could be accessed properly on various devices. After the improvement of the Lingualy application, an evaluation using the System Usability Scale (SUS) resulted in an average score of 74.8, falling into the category of “Acceptable”, with a predicate of “C” and a rating of “Good”. This research concludes that user-centered UI/UX design makes language learning more effective and enjoyable, and enables proficiency without the limitations of time and place.

Abstract

The F1Math application was developed to assist students in learning mathematics through an interactive concept inspired by Formula 1 racing. This study aims to evaluate the effectiveness of the grey box testing technique in testing the F1Math application. The testing method used is grey box testing with a Regression testing approach, combining an analysis of the application's internal structure and observation of its external behavior. The testing process began with analyzing the system specifications and source code, followed by unit Testing, integration Testing, and regression Testing. User simulations across various game levels were also conducted. The results indicate that the grey box testing technique is effective in detecting bugs during the early stages of development. This approach accelerates the debugging process and enhances application stability, especially in critical areas such as gameplay features and mathematical calculations. In conclusion, the implementation of the grey box testing technique significantly contributes to improving the quality of the F1Math application. This approach successfully combines the strengths of code-based and user-behavior-based Testing, resulting in a more reliable and efficient application.
