Abstract

This research aims to redesign the user interface of the Reparation application, a motorcycle repair service in Makassar, using the Goal-Directed Design (GDD) method. Data collection was carried out through interviews and questionnaires with 20 users, and the data was processed using the System Usability Scale (SUS). The initial test obtained an average SUS score of 46.375 with a "Not Acceptable" rating. The second test used a new design prototype, which achieved an average score of 84.5 with an "Acceptable" rating. These results indicate an improvement in interface quality from the "Poor" category to "Excellent". With an average score of 84.5 in the second test, the new design has met the standard average SUS of 68. Thus, the prototype design using GDD has successfully met user needs and produced an attractive and user-friendly interface.

Abstract

Hi Jobs! is a mobile application that will help people find work because it provides various information concerning job vacancies. This application is still relatively new and has never been tested before. However, this application already has several criticisms and suggestions from users regarding problems that had occurred when using the Hi Jobs! application. The problems that occurred were related to aspects of application usability. Therefore, usability testing is needed to determine the effectiveness, efficiency and user satisfaction when using the Hi Jobs! application using Performance Measurement and Concurrent Think Aloud techniques. The test was conducted on 20 participants who were divided into two categories, advanced and novice. The results of the study showed that advanced participants had a success rate of 96% with a total of one failed task, while novice participants had a success rate of 89% with a total of four failed tasks. The average time for participants in the advanced category was 30 seconds and the novice category was 37 seconds. Based on the results of interviews conducted, there were problems with 4 application features of the Hi Jobs! application. In conclusion, this application was very effective but it was not efficient nor has it meet user satisfaction because there are some features that are difficult to find. Therefore, recommendations for improvement have been made based on the received criticisms and suggestions to meet user satisfaction.

Abstract

Search Buddy is a website that provides service search services accessible through any platform. To consistently meet users' expectations of the website's services, an analysis of the website is essential. The conducted research aims to implement the WebQual 4.0 method in analyzing the quality and user satisfaction of the Search Buddy website. The WebQual 4.0 method is a framework that encompasses three main dimensions: usability quality, information quality, and service interaction quality. This method is considered suitable as it measures website quality from the perspective of end users. The analysis results indicate that the variables of usability quality and service interaction quality have a positive impact on user satisfaction. However, the information quality variable does not have a positive impact on user satisfaction. The coefficient of determination analysis shows that the variables of usability quality, information quality, and service interaction quality collectively influence user satisfaction by 40.3%. Based on these findings, it is recommended to pay attention to the aspects of usability quality and service interaction quality present on the website. Additionally, there is a need to enhance the quality of information presented on the website to make it more informative, relevant, and user-friendly, thereby potentially elevating user satisfaction with the Search Buddy website.

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

Service Electronica Online (SERVIO) is a web-based application project developed to provide online repair services for electronic goods. SERVIO can be accessed online through the website (https://serviceonline.bopolewali.com). The usability of the SERVIO website requires a usability analysis with the aim of ensuring that the website is accepted and used by users, as well as identifying the shortcomings of the SERVIO website. Usability testing on the SERVIO website will be conducted using the Think Aloud method. Based on the results of the usability test of the SERVIO website, respondents believe that the flow of the website is still not understandable. After the errors found in the website display were identified, recommendations were provided in the form of design improvements. The changes in design can be found in the login menu, navigation, service messages, and service progress.

Abstract

Another World Reborn was developed using the Game Development Life Cycle (GDLC) method, which consists of six stages: initiation, pre-production, production, testing, release, and post-release. The initiation stage involved a literature study on RPGs and GDLC, as well as identifying player needs and initial game specifications. In the pre-production stage, a Game Design Document (GDD) was prepared, along with a storyline, character designs, UI sketches, gameplay flowcharts, and the selection of RPG Maker and legal community assets. The production stage included the creation of visual and audio assets, the implementation of turn-based gameplay, a battle system, dialogue writing, and the implementation of UI/UX. Testing was conducted in two stages: an alpha test using the blackbox testing method by an internal team, and a beta test with 15 high school students using the System Usability Scale (SUS). The test results showed that the game had good story and gameplay quality. The game was released in APK format through a personal website. The post-release stage included documentation, feedback collection, and version update plans. This project demonstrated that GDLC is effective in producing engaging and playable educational RPG games.
