Abstract

This study aimed to design and develop a prototype of an Arduino-based automatic ablution faucet to minimize water consumption and promote sustainable resource use in worship facilities. This study employed an engineering research approach using a prototyping method that included system analysis, hardware and software design, prototype construction, and performance evaluation. The developed system integrates a proximity sensor to automatically control the opening and closing of the faucet, a water flow sensor to measure water usage, and an LCD display to present real-time consumption data. Functional and usability evaluations were conducted according to the ISO 25010 standard through direct testing and user questionnaires involving 30 mosque congregants. The results indicated that the prototype effectively reduced water usage by an average of 44.03% compared to manual faucets, achieved a 100% functionality score from expert assessments, and received a usability rating of 87.8%, classified as “very effective.” These findings demonstrate that the system performs accurately, efficiently, and conveniently for small-scale mosques. The novelty of this research lies in combining the ISO 25010-based quality evaluation with a real-time monitoring system to ensure measurable performance and reliability. This innovation contributes to the advancement of intelligent water-saving technologies and supports environmental conservation through the integration of automation, sustainability, and user-centered design in the context of Islamic practices.

Abstract

This study aims to develop and evaluate an Arduino-based automatic ablution faucet designed to reduce water consumption through proximity sensing and real-time water-flow monitoring. Using an engineering research approach with a prototype development model, the system was constructed using an Arduino Uno microcontroller, a proximity sensor, and a water-flow sensor, followed by direct testing and usability evaluation involving 30 respondents. Functionality assessment was conducted by experts using the ISO 25010 framework, while usability testing employed a Likert-scale questionnaire. The results show that the automatic faucet successfully regulated water flow based on user presence and displayed real-time water usage on an LCD. Comparative testing between manual and automatic faucets demonstrated a 44.03% reduction in water consumption, with the prototype achieving 100% functionality and an 87.8% usability score, indicating that the system is operationally reliable, accurate, and user-friendly. Sensor calibration produced an average error rate of 1.2%, which falls within acceptable tolerance limits. The novelty of this research lies in its integration of dual-sensor technology, quantitative water-efficiency measurement, and ISO 25010-based quality evaluation within a single prototype framework an approach not commonly adopted in previous studies on ablution automation. The incorporation of real-time water monitoring also enhances the system’s practicality and contributes to technological advancements in water conservation and electrical engineering applications.
