Abstract

The problem in STMIK KHARISMA Makassar in this study is because the management of lecturer evaluations is only in the form of distributing questionnaires on lecture evaluations and does not produce a value that can be used as a reference for lecturers’ performance. The purpose of this study is the application of new performance appraisals and creating applications that can provide visual information for lecturers’ performance. The application that is built is a website that uses the PHP programming language and MySQL database. Data collection is done by conducting interviews and distributing questionnaires to determine the condition of the problem. From the results of the analysis obtained if perceptional assessment can be used as a standard assessment that has included the assessment of students, colleagues, and leaders. From the results of testing the application, it is known if the dashboard with perceptional assessment can provide information on the performance of the lecturer and provide an overview of how the lecturer performs. And then, from the information on the results of the persepsional assessment can be used for the needs of leaders in making decisions or others.

Abstract

The aim of this study is to implement Progressive Web Apps (PWA) technology on the Frizfoo website using the Express.js framework so that it can be accessed in the form of native applications via the user’s smartphone home screen and can be run offline. The implementation of PWA as one of the “should have” features aims to provide added value and improve website performance, as well as overcomes website limitations in displaying offline pages, and avoid the cost of developing native applications on various operating systems platforms. Data collection methods involve literature study and direct measurement using several tools. Testing included installable testing, PWA criteria, performance, size transferred resources, and offline mode. Components used in PWA include web app manifest, service worker, and cache storage. PWA implementation involves creating a web app manifest, service worker registration file, configuring service worker files, adding script tags, creating custom routes in Express.js, and testing PWA. The test results show that the Frizfoo website can be installed and used properly on various types of mobile devices. PWA was successfully implemented and met all PWA criteria, by getting a total score of 10 on Lighthouse and a total score of 25 on PWABuilder. The results of performance testing on Lighthouse and GTMetrix have increased by 36% after the implementation of PWA. The size of transferred resources has reduced from 3.1 MB to 1.8 MB and the website load time has decreased from 3.65 seconds to 826 ms so that the website can be loaded faster. And offline mode feature of the Frizfoo website is successfully used in offline conditions or with an unstable internet connection.

Abstract

This research involves the design of a mobile application prototype called Frizfoo using the User-Centered Design (UCD) approach to ensure the alignment between design and user needs. Primary data was obtained through interviews and observations of five Frizfoo users, using the "magic number five" approach to identify usability issues. The analysis results showed significant problems with some tasks. Furthermore, the research measured the time required to complete tasks (Time on Task) and the error rate (Errors) made by users. It was found that one user experienced delays in completing some tasks, attributed to factors such as age and lower technological skills. However, these delays were still within acceptable limits. The average error rate for all tasks was approximately 5.30%. The testing results indicated that the designed interface of the mobile application had low error rates, efficient task completion times, and a high level of user satisfaction. Adjustments and design improvements made based on the testing results had a significant positive impact on the performance and responsiveness of the mobile application prototype. This research provides a clearer insight into the quality of the Frizfoo application prototype design and serves as a foundation for further development that better aligns with user needs.

Abstract

This research aims to analyze the usability of the user interface in the VirCle application using the usability metric method. Data were collected through observation testing, questionnaires, and interviews. The research results indicate problems in task success, particularly in the photo uploading process that requires a description before posting. Although some users exceeded the predetermined time in the time on task, the overall required time is relatively short. The error rate is low, only around 4%. The System Usability Scale (SUS) questionnaire results show an average score of 75, which falls into the "Good" category. The interview results obtained positive user responses, although some problems were identified. Overall, the VirCle application has good potential and usability, with some improvements needed, especially regarding photo description filling and toolbar icons. This research is expected to contribute to application developers in improving the usability of VirCle and providing a better user experience.

Abstract

This study redesigns the category feature interface on the WarShop application using the user-centered design method to improve the user experience. The goal is to make it easier for users to find the products they want specifically and quickly. Data was obtained through interviews and observations of 10 WarShop users, where 9 users felt that the existing category features were not specific, causing users to take longer to find the products they wanted. The user-centered design method was chosen because it involves users from the beginning of the design process, resulting in a better interface that meets user needs. This interface design resulted in a more specific category feature that helps users find items directly according to the category they are looking for, and provides recommendations for similar products based on the product being searched for using keywords or the product being displayed. After the redesign, an evaluation was carried out using testing with the metrics task success, time on task, and error metrics with five users who had been previously interviewed, based on research indicating that the majority of usability issues can be found by the first five users tested. There were no problems found in the task success test and the error test resulted in an average error rate for all tasks of 0%, while in the time on task, some users exceeded the time limit. However, this is because users were interested in other products displayed based on category and recommendations.

Abstract

The fashion and garment industry is growing rapidly, making individuals' needs for appropriate clothing continue to increase. Jahitku is a web-based platform created so that tailors can reach more customers, provide good service, and customers get information according to their needs at affordable prices and high quality. However, Jahitku has problems in optimizing the relevant website, inconsistent layout, button navigation that doesn't work, and using colors that lack contrast. The aim of this research is to redesign the Jahitku website to achieve better user satisfaction. In this research, by applying the Design Thinking method, existing functions are analyzed and their usefulness is tested on the System Usability Scale (SUS). Making a prototype using the Design Thinking method produced significant recommendations through SUS testing, resulting in a final test score of 78.775. This score has increased compared to the previous score of 48.125 which was still in the low category. This improvement shows a significant improvement in user experience from “Poor” to “Good”. Thus, it can be concluded that by updating the appearance of the Jahitku website, the user experience can be improved and the Jahitku website can become more effective and attractive to users.
