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

Potio was a mobile-based alarm application that functioned as a medication reminder for users who often forgot their medication schedules, which consisted of several features, such as adding alarms, medication history, themes customization, and medicine information research. In its development, this application used a MySQL database to store the results of inputting alarm data and medicine information. However, with the increasing amount of data that needed to be managed, researchers faced challenges in data management, because the very large number of medicines needed to be inputted manually, so it took longer and there was the potential for errors in data input. Therefore, the development of a medicine information search feature in the Potio application was carried out using one of the models, namely Gemini AI, by obtaining an Application Programming Interface key to be implemented into the medicine information search feature, followed by a prompt technique to provide effective output. The results of testing using Blackbox Testing with test cases showed that Potio successfully utilized Gemini AI for the medicine information search feature, eliminating the need for manual input of medicine information into the MySQL database.

Abstract

KAMI ADA is a digital platform startup that connects the public with service providers such as well drilling, toilet suction, and iron welding through the website kamiada.com. Currently, KAMI ADA has 56 users, but feedback indicates concerns about the website's poor appearance. Measurements using the System Usability Scale (SUS) on 20 users resulted in a score of 42.875, with a grade of F, a rating of "poor" and an acceptance level of "not acceptable." This score indicates that the majority of users experienced difficulties, indicating a very poor user experience and the need for design improvements. To address this issue, KAMI ADA will redesign the system on the website using the User-Centered Design (UCD) method. The UCD approach was chosen because it places the user as the main focus in every design stage, with the hope of creating a system that is functional, satisfying, efficient, and enjoyable for users. Through this redesign, KAMI ADA aims to increase the value of services, strengthen relationships with users, and encourage sustainable business growth.
