Abstract

The main goal of this study is to develop charging stations that use solar energy as an environmentally friendly alternative, in order to reduce carbon dioxide gas emissions produced from burning fossil fuels. The method used is qualitative with data collection through system observation and analysis of solar panel performance with dual-axis technology that can follow the movement of the sun. The results of the study show that the use of solar panels equipped with dual-axis actuators can increase the efficiency of sunlight absorption, so that the power produced is more optimal. From the analysis, it was found that these stations not only provide an efficient charging solution, but also contribute to a reduction in carbon footprint, with the potential for significant reductions in CO2 emissions. The conclusion of this study shows that the development of solar energy-based charging station technology is a strategic step in supporting the transition to a more sustainable energy source in Indonesia.

Abstract

Indonesia's rising residential electricity consumption and the passive nature of conventional electrical terminals create risks of energy waste, overload, and fire hazards, since existing terminals offer no monitoring or remote-control capability. This research aimed to design and implement Smartura, an IoT-based smart electrical terminal integrating remote load control, real-time monitoring of electrical parameters, a usage timer, automatic overload protection, and energy/cost estimation in a single system. The system uses an ESP32 microcontroller, a relay actuator, ACS712 and ZMPT101B sensors for current and voltage sensing, and a website connected to Firebase for authentication and real-time data exchange. The method comprised a literature study, observation, hardware and software design, and performance testing on data collected from 5–11 June 2026. Results showed reliable on/off control through the dashboard, recording 5,785 relay-on and 408 relay-off data points out of 6,193 readings. Voltage and current monitoring achieved MAPE values of 1.69% (very good) and 12.38% (fairly good). The timer and overload-protection features worked as designed, disconnecting the relay above a 5.45 A/1,200 W threshold. Average measured values were 213.15 V, 0.164 A, 35.07 W, 3.62 kWh, and an estimated cost of Rp5,229.29. Smartura demonstrates an integrated, low-cost IoT solution for residential electrical monitoring and control.
