Public Fuel Filling Stations (SPBU) are important facilities that provide various types of fuel such as gasoline, diesel, and Pertamax to meet the needs of motorized vehicles. The existence of SPBU greatly helps the public in obtaining fuel at a more economical price compared to purchasing retail. However, the transaction system at SPBU generally still uses conventional methods, such as cash payments or the use of debit/credit cards that have not been fully integrated with an efficient digital system. The use of RFID (Radio Frequency Identification) technology has been implemented as a non-cash transaction method at several SPBUs, but this system still has various weaknesses, such as limited device compatibility and delays in transaction processing. This prompted the author to develop the concept of an independent SPBU based on modern technology that is more efficient and secure. The proposed innovation includes the use of contactless smart cards and coin acceptors for the payment system, allowing users to make self-service transactions without operator involvement. In addition, the author also added several supporting components such as proximity sensors, which function to detect the presence of vehicles or people around the SPBU area. These sensors can help in saving electrical energy by activating the system only when needed. Another component is a vibration sensor, which plays a crucial role in detecting excessive vibrations that could potentially cause leaks. If excessive vibration is detected, the system automatically closes the solenoid on the pump to prevent the risk of fire or damage. By integrating this technology, the autonomous gas station system is expected to improve operational efficiency, user convenience, and safety during the automatic refueling process. This development is expected to be an innovative solution for modernizing the gas station system in Indonesia.

A conductor, as a material that allows the easy flow of electric charge, plays a crucial role in various electrical and electronic applications. Understanding how elementary charges, particularly electrons, configure and move within a conductor, especially one with a square shape, is essential for analyzing and designing efficient electrical devices. This article discusses the configuration of elementary charges in a square conductor through simulations using a mechanics and electrodynamics approach, focusing on the interactions between charges to achieve a stable configuration. The simulation is conducted by placing charges randomly around the square conductor. The electro-dynamic interactions between charges cause them to arrange themselves in the most stable positions, where each charge interacts to minimize the system's energy. Although a stable configuration is achieved, fluctuations in the total system energy are still observed, approximately 1.33×10⁻³⁵ Joules. These fluctuations indicate that, despite stability, the system continues to experience dynamics that affect the overall energy. Particles at the corners of the conductor move faster than those on other sides, contributing significantly to the measured energy fluctuations. This charge configuration forms an electric field profile in the shape of a square, with the field being concentric, moving from the inside out of the conductor. This indicates that the electric field distribution is more concentrated inside and gradually decreases toward the outside. Furthermore, the distribution of particles on each side of the conductor is not uniform. There are deviations up to 4% from the expected distribution, and these fluctuations occur within a range of ±1 particle. This phenomenon provides deeper insights into the behavior of charges in a square conductor. Understanding this is important for designing electrical and electronic systems. Although the conductor reaches stability, the energy fluctuations that occur still play a role in optimizing electronic devices. The approach combining mechanics and electrodynamics is very useful for understanding the interactions between charges and electric fields, which can be applied to modern electrical technology.
