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.

Abstract

In the modern era, electrical energy has evolved into an indispensable cornerstone of societal function, particularly in dense urban environments, where infrastructure demands are relentless. Ensuring both the effectiveness and efficiency of energy distribution from generation plants to end consumers is a paramount challenge for utility providers. A significant hurdle in this process is the inevitable phenomenon of energy loss, which degrades system performance and increases operational costs. This study provides a comprehensive analysis of power loss within the medium-voltage distribution network at PT. PLN (Persero) ULP Panakkukang. Several critical factors contribute to these inefficiencies, most notably the load imbalance between phases, which leads to neutral current flow and resistive heating generated within conductors. Furthermore, physical degradation, such as poor conductor connections, acts as a persistent impediment to seamless distribution. To quantify these issues, this research employs a dual-methodology approach: utilizing Electrical Transient Analyzer Program (ETAP) software alongside rigorous manual calculations to measure voltage drop and real power loss. These findings indicate that the losses fluctuate significantly in response to shifting load conditions throughout the day. Ultimately, this research serves as a vital technical reference for optimizing grid performance and enhancing the reliability of future electricity distribution systems.
