Abstract

The rapid growth of the e-commerce industry requires mobile applications to provide intuitive interfaces that support efficient and satisfying user interactions. Shopee, one of the largest e-commerce platforms in Indonesia, continues to receive user complaints regarding visual density, complex navigation, and excessive interface elements that may increase users' cognitive load. This study aims to evaluate the usability of the Shopee mobile application by employing a mixed-methods approach that combines quantitative and qualitative techniques. Quantitative data were collected using the System Usability Scale (SUS) questionnaire administered to 150 respondents, while qualitative insights were obtained through the Concurrent Think-Aloud (CTA) method involving 10 participants performing representative shopping tasks. The findings reveal an average SUS score of 73.18, indicating a Good usability rating with an Acceptable level of user acceptance. The relatively favorable score is strongly influenced by users' familiarity with the platform, reflecting learned behavior developed through repeated use. However, the qualitative findings identified several usability issues, including the absence of a search feature on the shopping cart page, visual distractions caused by autoplay mechanisms, inconsistent navigation flow, and a suboptimal hierarchy of product information. Based on these findings, this study recommends redesigning the interface hierarchy, minimizing unnecessary visual clutter, introducing contextual search functionality, and simplifying navigation to improve interaction efficiency and overall user experience.

Abstract

This study aimed to determine the effectiveness of implementing the Problem-Based Learning (PBL) model assisted by Quizizz in improving students’ learning outcomes in Informatics, particularly on the topic of data sources, among tenth-grade students at SMA Negeri 2 Paguyaman. The study employed a quantitative approach with an effectiveness research design using a pre-experimental method in the form of a one-group pretest-posttest design. The research subjects consisted of tenth-grade students of SMA Negeri 2 Paguyaman. Data were collected through observation, interviews, documentation, and learning achievement tests in the form of pre-tests and post-tests administered using the Quizizz platform. The data were analyzed using descriptive quantitative statistics, including the calculation of mastery percentages and N-Gain scores. The results indicated that the average student learning outcomes increased from 68% in the pre-test to 79% in the post-test. The N-Gain score of 0.4 was categorized as moderate, indicating that the implementation of Problem-Based Learning assisted by Quizizz was moderately effective in enhancing students’ learning outcomes in Informatics. Furthermore, the use of Quizizz as a digital assessment tool contributed to a more interactive and engaging evaluation process while providing immediate feedback to students. These findings suggest that integrating Problem-Based Learning with digital learning platforms such as Quizizz can effectively support student learning and improve academic achievement.

Abstract

This study aimed to develop an Android-based interactive learning media called DynaVersity and to determine its effectiveness in improving students' learning outcomes in the Computer Systems topic of the Informatics subject at SMK Negeri 1 Boalemo. The study employed a Research and Development (R&D) method using the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research subjects were 21 tenth-grade students. Data were collected through observations, interviews, expert validation, and pretest-posttest assessments. The validation results indicated that the learning media achieved a score of 92.6% from the media expert and 96% from the subject matter expert, both categorized as highly valid. Student responses reached 93.7%, which was categorized as very good. The effectiveness results showed an improvement in students' learning outcomes, as evidenced by the increase in the average pretest score from 65.2 to 82.8 on the posttest. Furthermore, the N-Gain analysis yielded a score of 0.50, which falls into the moderate category. The findings indicate that the developed Android-based learning media is effective in enhancing students' learning outcomes in Informatics.
