<![CDATA[This study develops a Tetris game controlled through hand gestures using a machine learning model. The primary objective of this research is to create an interactive and responsive gaming experience by utilizing hand gesture detection as the main control mechanism. A hand gesture dataset was collected from videos segmented into individual frames, which were then analyzed using MediaPipe to detect and label gestures. The machine learning model employs a Convolutional Neural Network (CNN) trained to recognize hand gesture patterns and translate them into commands within the game. After implementation, an evaluation was conducted by distributing questionnaires to 18 Informatics students at Adzkia University to assess the system's comfort and responsiveness. The questionnaire results showed a high satisfaction level, with an average score of 84.56, covering evaluations of control ease, gesture detection accuracy, and system responsiveness. The average score for ease of use reached 85, indicating that the majority of users found the gesture-based controls comfortable. This study demonstrates that applying machine learning models in gesture-based control games can provide a more interactive and responsive experience, with potential applications in other interactive technologies.]]>

<![CDATA[PT. XYZ is a company engaged in the field of digital information technology and telecommunications services in Indonesia, utilizing Fiber To The Home (FTTH) technology as a telecommunications solution to connect service providers with residential customers. PT.XYZ faces challenges in managing FTTH data due to the manual recording of information in books, which can lead to inaccuracies, hinder data accessibility, and complicate the understanding of network transmission point distribution. A viable approach to address this issue is the implementation of a management information system capable of managing FTTH data and visualizing the distribution of transmission points based on current data. This project aims to create a web-based FTTH management information system to enhance the efficiency of fiber optic network data management at PT.XYZ. This research employs the PIECES technique (Performance, Information, Economy, Control, Efficiency, Service) for requirements analysis and system assessment. The system is built using the Waterfall methodology, which includes phases of requirements analysis, design, implementation, and testing. The results of black-box testing indicate that all scenarios effectively meet the specified requirements. Usability testing using the PIECES framework shows that the average user satisfaction falls within the "Satisfied" category across all criteria. This system offers a more effective and organized FTTH data management solution, capable of visualizing the distribution of network transmission points, thereby assisting operators in their daily operations.]]>

<![CDATA[Authentication based on one-Time Password (OTP) is one method that is widely used in securing access to web systems. This study aims to analyze in depth the effectiveness and weaknesses of the OTP authentication system in preventing unauthorized access. Through a qualitative approach based on literature studies, as well as comparisons between other authentication methods, it was found that OTP is able to increase a significant additional layer of security, especially when combined with other authentication methods such as passwords or biometrics. However, this system still has various weaknesses, such as the risk of phishing attacks, man-in-the-middle (MITM) attacks, and vulnerabilities to SIM swapping attacks, especially in the implementation of OTP via SMS. Dependence on user devices and communication networks is also a limiting factor in the effectiveness of OTP. This study provides recommendations for the implementation of strengthening measures such as Multi-Factor Authentication (MFA), the use of authenticator applications, and the implementation of end-to-end encryption to reduce security risks. The results of this study are expected to be a reference for system developers and organizations in choosing and implementing authentication methods that are more secure and in accordance with current cybersecurity needs.]]>

<![CDATA[This study aims to analyze the effect of Green Human Resource Management (GHRM) on employee commitment, with work motivation as a moderating variable at the West Sumatra Department of Transportation. This research employs a quantitative method with an explanatory research approach, collecting data through a survey of 95 employees and analyzing it using SEM-PLS. The results indicate that GHRM has a positive and significant effect on employee commitment. Work motivation also significantly influences commitment but fails to moderate the relationship between GHRM and employee commitment. These findings confirm that effective GHRM implementation can enhance employee loyalty and engagement without being influenced by individual motivation levels. This study provides implications for organizations in developing environmentally-oriented human resource policies to improve employee performance and retention.]]>
