Abstract

Currently, fun learning is rarely used by educators, educators more often use the concept of learning by delivering material and assignments carried out full time during learning hours which can make students bored. The concept of gamification in learning is a concept that takes game elements which is expected to make students motivated and enthusiastic in understanding the lessons given by educators. The aim of this research is to apply gamification to the Learning Management System (LMS) so that educators can create content such as quizzes, interactive videos and presentations. In the system there are rewards that make students interested in doing assignments because there is a sense of satisfaction like playing games and can help educators to find out their students' understanding. In making this system, the Multimedia Development Life Cycle method was used with 6 stages, namely concept, design, material collection, assembly, testing and distribution. The final result of this research is a gamification concept in the LMS that applies the LevelUp and badge features, namely giving awards and points by displaying the results obtained in the form of increasing the level of each student on the leaderboard and giving badges according to the criteria determined by the admin and lecturer.

Abstract

Independent learning is an activity carried out by students with the aim that students can explore the material provided by the lecturer. Therefore, the Daily Report application is here to help students report independent learning activities carried out by students. Problems arise when students find it difficult to use the Daily Report application due to several things such as inappropriate button placement, input form design that is too rigid and using inappropriate fonts and icons. The aim of this research is to develop the Daily Report application design by applying the user-centered design methodology. The user-centered design methodology is an application design development methodology that focuses on user needs. This research resulted in the development of the Daily Report application design with test results using the usability scale system obtaining an average usability score of 73 with a scale grade of C and an adjective rating of Good, which proves that the development of the application design makes it easier for students to use the Daily Report application.

Abstract

Student engagement in online learning is an important factor that can affect learning outcomes. One indicator of engagement is facial expression. However, research on facial expression detection in online learning environments is still limited, especially in the use of the YOLOv8 algorithm. This study aims to compare the performance of several YOLOv8 variants, namely YOLOv8x, YOLOv8m, YOLOv8s, YOLOv8n, and YOLOv8l in recognizing six facial expressions: happy, sad, angry, surprised, afraid, and neutral. Student facial expression data was collected through the Moodle platform every 15 seconds during the learning process. All models were trained using 640x640 pixel images for 100 epochs to improve facial expression detection capabilities. The main contribution of this study is to provide a comprehensive analysis of the effectiveness of YOLOv8 in detecting student facial expressions, which can be used to improve the online learning experience. The evaluation results show that the YOLOv8s model has the best performance with the highest mAP of 0.840 and the fastest inference speed of 2.4 ms per image. YOLOv8m and YOLOv8x also performed well with mAP of 0.816 and 0.815, respectively. Although YOLOv8x had the slowest inference speed, it was superior in detecting fear, happiness, and sadness expressions with mAP above 0.9. YOLOv8n had mAP of 0.636, while YOLOv8l achieved mAP of 0.813 with an inference speed of 9.1 ms per image. This study shows that the YOLOv8 algorithm, especially YOLOv8s, can be an effective solution to analyze student engagement based on their facial expressions during online learning.
