Abstract

The objective of this community service project is to explore and strengthen the role of mosques as ecological agents in mitigating climate change through the innovative “Compost Waqf” initiative. Conducted at Nurul Amin Mosque in Metro City, this study employed a Community-Based Research (CBR) and Participatory Rural Appraisal (PRA) approach, involving 120 participants, including mosque administrators and congregants. This program integrates Islamic teachings with practical solutions for managing organic waste, enhancing environmental literacy, and fostering climate action awareness among mosque attendees. By focusing on waste segregation and composting, the initiative significantly reduced organic waste, minimized greenhouse gas emissions, and provided sustainable economic benefits for mosque operations and community empowerment. This study demonstrates how integrating Islamic environmental values with sustainable practices transforms mosques into centres of ecological education and local climate action. The Compost Waqf initiative bridges spiritual responsibility with environmental stewardship, providing a scalable and replicable model for mosques to address global climate challenges while fostering collective awareness and behavioural change within communities. The research highlights the strategic role of mosques in promoting ecological resilience, positioning them as key actors in climate change mitigation efforts.

Abstract

Technological advances in electric motor control systems have encouraged the adoption of more efficient and adaptive control devices. One of the commonly used devices is the Variable Frequency Drive (VFD), which plays a role in regulating the speed and torque of a three-phase induction motor. This study aims to analyze the effect of a three-phase induction motor rotational speed control system using a Powtech brand VFD. The main focus of this study is to evaluate motor performance in terms of rotational speed, torque, energy efficiency, and system response to frequency variations provided by the VFD. The research method used is an experimental approach, where a three-phase induction motor is connected to a Powtech VFD and tested under various load conditions and operating speeds. The test results show that the use of a Powtech VFD is able to provide more accurate speed and torque control, and contributes to increasing the efficiency of induction motor operation. In addition, smoother and more responsive rotation control can be achieved through flexible frequency adjustment, resulting in reduced power consumption and increased overall system performance. This study contributes to the development of VFD technology in three-phase induction motor drive systems, especially in efforts to improve energy efficiency in industrial applications.
