Abstract

Checking the identity of motorcycle owners when leaving the college area is a mandatory activity for security officers to ensure that vehicles entering and exiting the college are the same driver. The conventional checking process often causes the impact of vehicle queues when the volume of vehicles increases. Therefore, an intelligent system is needed to detect multi-plate vehicles automatically. One approach in the world of image detection of an object is the use of the YOLO (You Only Look Once) algorithm. This algorithm predicts bounding boxes and possible classes in a single frame. This research divides objects into 3 classes, namely vehicles, driver's faces, and vehicle plates. The dataset used was 74 varied images consisting of 50 training data, 12 validation data and 12 testing data. The image was trained using 300 epochs and a batch size of 8 and resulted in an F1 score calculation for detecting objects reaching 92%.

Abstract

Writing scientific articles is an essential academic competency for students of the Teacher Professional Education (PPG) program. However, many students face difficulties in understanding research methodology, academic structure, as well as data processing and scientific language. To address this issue, Universitas Negeri Medan (UNIMED) initiated a Collaboration for Scientific Article Writing Assistance involving lecturers, mentor teachers, and PPG students. This study employed a qualitative approach using a case study method to evaluate the program’s effectiveness. Data were collected through observations, interviews, and document analysis of article drafts before and after the mentoring sessions. The results show that this mentoring program improved students’ academic competencies, with 85% of participants acknowledging the benefits of the guidance in understanding the structure and quality of scientific writing. Additionally, 70% of students expressed high satisfaction with the program, with the increased number of articles submitted to national and international journals serving as an indicator of its success. However, challenges remain, such as limited time and restricted access to scientific references. Therefore, it is recommended to improve access to academic resources and develop online platforms to support more flexible mentoring. Overall, the results of this study affirm that academic mentoring collaboration is an effective strategy to enhance the scientific writing skills of PPG students and strengthen the academic culture in higher education environments.

Abstract

The research was conducted due to the lack of interesting learning media, thus making students' interest in physics subjects to study physics low and resulting in unsatisfactory student learning outcomes.  This research aims to develop digital student worksheets based on Problem Based Learning (PBL) on hydrostatic pressure material for grade XI high school. This research is a Research & Development (R&D) study using the ADDIE model which consists of stages (Analyze, Design, Development, Implementation, and Evaluation). The subjects of this study were students of grade XI high school. The results of feasibility validity by experts analyzed with Aiken'V index obtained a result of 0.82 with a very feasible category.  The results of practicality by teachers 95% (very practical), students in small groups 90% (very practical), and large groups 86.44% (very practical) and in the effectiveness test obtained the results of the gain score of the difference between pretest and posttest scores showed an average in small groups of 0.76 while in large groups 0.77 with the effective category.  Based on this information, it is concluded that the PBL-based student worksheet on hydrostatic pressure material developed by researchers and tested at SMA Negeri 2 Binjai is feasible to use, very practical and effective. This PBL-based digital student worksheet on hydrostatic pressure material can be a reference for the development of similar teaching materials and can be teaching materials used in schools.

Abstract

This research aims to develop a motorcycle rider registration system using facial recognition technology that can improve the efficiency of rider data management. This system is designed to identify and authenticate riders with high accuracy, thereby simplifying the registration and monitoring process. The methods used in this research include collecting rider facial data through cameras, image processing for feature extraction, and implementing a facial recognition algorithm. Testing was conducted in several locations with varying lighting conditions and viewing angles to ensure the system's robustness. The results show that the developed system is capable of achieving facial recognition accuracy of up to 95%. In addition, this system provides an intuitive user interface to facilitate the registration and data management process. With the implementation of this system, it is expected to reduce the time and costs required in managing motorcycle rider data, as well as improve safety and comfort while riding.
