Analysis of the Efficiency of Using Water for Wudu in Modern Mosque Plumbing Systems

This study focuses on analyzing the efficiency of water usage during ablution in mosques, aiming to identify the factors causing inefficiency and propose solutions aligned with sustainability and Islamic values. Ablution is essential for Muslim prayer, yet modern mosques often neglect water efficiency, leading to waste and high operational costs. A mixed-methods approach was employed, combining observations, water discharge measurements, and surveys from 35 congregants at an urban mosque. The results showed an average ablution water consumption of 2.47 liters per person, with significant variation, primarily due to faucet usage behaviors. The survey also revealed that 45.71% of participants viewed water use as inefficient, with mixed responses regarding the implementation of automatic faucets. These findings underscore that water conservation cannot be achieved solely through technical solutions like sensor faucets or water recycling systems. Instead, it requires integrating Islamic values and education to encourage behavioral change among mosque-goers. By promoting awareness and responsible water use, mosques can become role models in environmental conservation. This study highlights the importance of combining technical engineering solutions with spiritual values, contributing to a more sustainable and efficient use of resources in mosque facilities while adhering to Islamic principles.
