Abstract

This study aims to determine the legal use of the FaceApp application in terms of the Qur'an, sunnah, and opinions of the scholars, as well as its relation to the problem of changing God's creation. This study uses descriptive-qualitative with content analysis and library research technique. The results showed that: first, FaceApp is an application that can change face photos using technology in the form of neural networks that automatically produce very realistic facial transformations in photographs. The opinions of the scholars in the matter of changing God's creation are: 1) neutering humans and animals ; 2) changing physical form; 3) make a tattoo on the body; 4) change the religion of God. Second, the legal use of the FaceApp application in an Islamic perspective by the scholars was divided into two: some scholars banned the use of the FaceApp application and others allowed it. Nevertheless, the majority of the scholars chose to forbid it, based on the evidence in the Qur'an and related hadith and the number of violations and harms posed by this application.

Abstract

This community service focuses on the application of wearable technology in the form of Mosque Watches and Portable Al-Qur'an Watches, which are designed to support Muslim worship practices by increasing accessibility to information on prayer times and the text of the Al-Qur'an. This activity involved structured training attended by 25 participants, including mosque administrators and congregation, to ensure understanding and ability to utilize this device optimally. The results of the training showed a high level of participant satisfaction with aspects such as usefulness, quality, suitability for needs and ease of use of watches. Despite challenges such as limited digital literacy, the evaluation showed significant improvements in participants' ability to integrate this technology into their daily lives. The success of this program indicates that the integration of technology in religious practice has great potential to provide real benefits for society, and can be an inspiration for further developments in religious technology in various communities.

Abstract

The development of digital technology demands mastery of 21st century skills, particularly the 4Cs (Critical Thinking, Creativity, Collaboration, Communication). However, conventional microcontroller learning is often limited to technical aspects without training these skills. This research aims to develop a microcontroller simulator based on AI (Artificial Intelligence) and IoT (Internet of Things) as an interactive media to improve 4C skills in digital technology learning. The research method uses a Research and Development (R&D) approach with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The simulator is designed with machine learning integration for learning difficulty adaptation and IoT for cloud-based project simulation. Validation was conducted through expert tests (pedagogy, AI, and embedded systems experts) and field trials on engineering students with questionnaire instruments, observations, and 4C skills tests. The results of the developed Simulator are proven to improve the understanding of microcontroller concepts while training 4C skills, with the following results: 1) Critical Thinking: Participants were able to analyse problems 25% faster through AI-based case simulation. 2) Creativity: There was a 30% increase in the variety of IoT project solutions generated. and 3) Collaboration & Communication: Teamwork effectiveness improved based on the collaboration rubric assessment. The implications of this research can be applied in technical education curriculum, vocational training, or STEM/STEAM development.

Abstract

This study developed an object detection system based on 8 proximity sensors implemented in a line follower robot using a switching algorithm. The system is controlled by an Arduino Nano microcontroller and displays detection results on a 16x2 LCD. The switching method is employed to read the sensors alternately, thereby reducing channel interference and lowering power consumption without compromising reading speed. Each sensor is calibrated with a predefined threshold to convert analog readings into digital signals, which are then visualized as icons or underscore symbols on the display. This research follows an experimental approach involving hardware design, microcontroller programming, and direct testing on a robotic track. The system was tested in five different track position scenarios. The results show that the system consistently and responsively detects objects. The switching method proved effective in improving reading efficiency and enhancing the robot’s navigation stability for accurate line following..

Abstract

The development of energy-efficient robotic systems has become increasingly important, particularly in servo-driven robotic arms where continuous PWM signals lead to unnecessary energy loss and thermal stress. This study proposes an adaptive pulse-width modulation (PWM) algorithm designed to activate servo signals only during motion phases and automatically deactivate them once the target position is reached. A four-degree-of-freedom robotic arm prototype was developed using an ESP32 microcontroller, MG90S servos, and ACS712-based current monitoring to evaluate power efficiency under conventional continuous PWM and the proposed adaptive control. Experimental results demonstrate a 28–33% reduction in average power consumption, a decrease of 6–8 °C in servo operating temperature, and the preservation of positional accuracy within ±5%. These findings confirm that significant energy savings and thermal improvements can be achieved without modifying hardware components. The proposed algorithm offers a practical, lightweight, and software-based optimization approach suitable for educational, research, and low-power robotic applications. This work introduces a distinct adaptive activation strategy that fully disables PWM in steady-state conditions, representing a low-cost and effective contribution to sustainable servo control.
