Abstract

SMK Karya Abadi Sumedang has limitations in terms of Teaching Factory (TeFa) facilities, particularly in the field of Retail Business, as a result of which students do not have the opportunity to gain direct experience in modern business management. Telkom University is collaborating with industry partner PT Sinai Teknologi Abadi to meet this need through the Smart Mini Market: Qmart program as part of its community service program. The goal is to improve student competence through the creation of Teaching Factory facilities for practical learning. The QMart application was developed as a Point of Sales (POS) system, along with modules and video tutorials as operational guides, as well as mini market facilities for practical training, and the implementation of QMart Operational Workshops. All of these stages are part of the implementation process. The results of the activity show that participants gained a better understanding of stock management, using digital cashier systems, and creating product marketing strategies. Teachers benefited from the integration of the Teaching Factory into the curriculum, while the school gained an independent business that can provide financial assistance. Additionally, the results of the questionnaire given to workshop participants indicate that this program meets their needs and is able to improve their understanding of mini market operations, particularly the QMART application. Participants' average initial scores increased from the moderate category (2.27–3.14) to the high category (4.03–4.68) after the workshop. The aspect of confidence in using the QMart application and encouragement for digital entrepreneurship showed the most significant improvement. It has been proven that the QMart implementation program is appropriate, efficient, and has a positive impact on improving the quality of vocational education in the scope of work practices through the Teaching Factory. This program also supports the link and match between vocational education and industry needs as well as the empowerment of the surrounding community.

Abstract

This research develops a virtual mouse control system that uses real-time hand gesture recognition implemented on an ESP32-CAM–based Internet of Things (IoT) platform. By leveraging OpenCV for image processing, the system translates hand gestures into corresponding mouse actions, including cursor movement, clicking, and scrolling. The study evaluates system performance under different lighting conditions and Wi-Fi speeds. Results show that higher Wi-Fi speeds significantly reduce latency, enabling smoother real time gesture recognition and high definition video output, while lower speeds lead to noticeable delays and reduced accuracy. The system successfully enables remote cursor control through camera captured hand gestures, supporting functions such as left click, right click, scrolling, and dragging. In latency tests performed with an internet speed of approximately 60 Mbps, the system achieved an average delay of about 50 milliseconds. Under optimal lighting conditions with minimal background interference, it accurately tracked hand movements and recognized gestures such as pointing, clicking, dragging, and scrolling in real time, achieving an accuracy rate of 95%. Despite its lower resolution compared to conventional webcams, the ESP32-CAM proves to be an effective solution for virtual mouse control, particularly in scenarios where high-resolution imaging is unnecessary. Its IoT capabilities support remote operation, allowing users to control the virtual mouse from a distance as long as both the ESP32-CAM and the computer remain connected. Overall, the findings highlight the ESP32-CAM based IoT platform as a viable alternative for gesture based interaction in real applications, although further enhancements are needed to improve performance in challenging environments.
