Abstract

Abstract. Kindergarten-aged children are going through an important period of cognitive development, such as the ability to think concretely, including recognizing simple geometric shapes such as circles, triangles, and squares. However, many children find it difficult to understand the basic concepts of two-dimensional shapes.Purpose: It is necessary to develop prototype learning aids in the form of intelligent systems in two-dimensional shapes applications for kindergarten students, which utilize information technology and object visualization directly through cameras on smartphones. This is expected to increase children's learning motivation and help strengthen their understanding of two-dimensional shapes.Methods: The research combines Waterfall and Agile methodologies, tailoring them to four stages: plan and discovery, analysis and design, application development, and testing. Testing gathers accuracy with 120 smartphone-collected data points for square, triangle, circle, and pentagon shapes. Also, usability testing based on learnability, efficiency, memorability, error handling, and satisfaction, was obtained from six kindergarten teacher questionnaires and quantitatively processed.Results: The application achieves an accuracy rate of approximately 79%. Notably, accuracy decreases with fewer corners, mainly due to low resolution or lack of focus, resulting in simplified detected shapes. Regarding usability, it is evident that the application has received positive feedback from users, particularly kindergarten teachers, who have given it an average score of 78.83.Novelty: Distinguished from previous research, the novelty of this study resides in its ability to capture objects through a camera, eliminating the need for predefined shapes within the application, and innovating by creating an educational tool aligned with the kindergarten curriculum to recognize two-dimensional shapes. The research contribution is the creation of an innovative learning tool for kindergarteners, merging smartphone technology with real-world objects to teach two-dimensional shapes, thus integrating technology into early childhood education effectively, which has urgency in efforts to improve the quality of learning.

Abstract

Troubleshooting records at the Information Technology Bureau of Mercu Buana University are still maintained manually, resulting in difficulties tracking reports, data duplication, and delays in handling IT disruptions. These conditions reduce service effectiveness and make it difficult to conduct comprehensive performance evaluations. Therefore, this study aims to design and implement a web-based troubleshooting recording information system capable of managing disruption reports in a structured manner, monitoring repair status in real time, and providing historical data for evaluating IT service performance. The system development method used in this study is the System Development Life Cycle (SDLC), which includes the stages of needs analysis, system design, implementation, and testing. The system was developed using the Laravel framework with a MySQL database to ensure centralised, secure, and integrated data management. System testing was conducted using the black-box testing method to ensure that all functions met user requirements. The test results show that the developed system can speed up the report recording process by up to 45%, increase transparency into the status of disruption handling, and facilitate data-driven decision-making. In addition, the implementation of this system supports the incident management process in accordance with the Information Technology Infrastructure Library (ITIL) principles. It contributes to increasing the efficiency, accountability, and quality of information technology services within the Mercu Buana University environment.
