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

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 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.
