Abstract

ABSTRACT The increasing use of battery-powered electronic devices necessitates efficient and fast charging solutions. This research aims to optimize battery charging at a charging station using the Maximum Power Point Tracking (MPPT) method integrated with Proportional Integral Derivative (PID) control. This method is chosen to address overshoot issues and speed up the stabilization process. The study begins with a literature review to understand the basic theory of MPPT optimization and PID control. Subsequently, hardware and software for the battery charging station were designed and developed. An Arduino ATMega328 microcontroller was used as the main controller, with an LCD to display charging information. Tests were conducted on 12V batteries with capacities of 5Ah and 9Ah. The results showed that using PID control in MPPT optimization successfully increased battery charging efficiency. The fastest charging duration was achieved for a 12V 5Ah battery with parameters Kp=6, Ki=9, and Kd=4, where the battery was fully charged in 19 minutes, and for a 12V 9Ah battery with parameters Kp=5, Ki=3, Kd=1, where the battery was fully charged in 27 minutes. Conversely, the longest charging duration occurred for a 12V 5Ah battery with parameters Kp=5, Ki=3, Kd=1, where the battery was fully charged in 34 minutes, and for a 12V 9Ah battery with parameters Kp=2, Ki=5, Kd=1, with a charging time of 38 minutes. The designed system was able to reduce input current and increase input voltage to reach the 14.5V set point, ensuring that there was no excessive voltage and current that could prolong battery life. This research demonstrates that the PID method in MPPT optimization is effective in accelerating and optimizing battery charging. Future research is expected to further develop this method to improve battery charging efficiency and duration.

Abstract

This study analyzes the power flow in the 150 kV Kedinding–Bangkalan Transmission Circuit using two simulation platforms, ETAP and MATLAB Simulink, to evaluate the performance of the transmission system and ensure the sustainability of the electrical power supply. Power flow analysis is essential in electrical systems to determine steady-state conditions, including voltage, current, active power, and reactive power. The Kedinding–Bangkalan circuit plays a crucial role in the stability of the electricity supply to Madura Island, which relies on energy from Java Island. The objective of this study is to compare the simulation results between ETAP, which uses the Newton-Raphson method for high accuracy, and MATLAB Simulink, which is more flexible in dynamic modeling. The simulation results show that the voltage profiles from both platforms are highly consistent, with minimal differences in active and reactive power (less than 2%). ETAP's simulation slightly underestimates the power loss (around 1.5%) compared to Simulink, but both show good stability under full load and fault conditions, with respective power losses recorded at 3.2% and 3.5%. These results indicate that both platforms can be used together to obtain a more comprehensive view of the transmission system's performance. Their integration allows for the exploration of more complex scenarios, such as load variations and faults, while enhancing simulation accuracy. This research is expected to contribute to the development of more effective and adaptive transmission system analysis methods, strengthening the reliability and efficiency of power systems, and supporting decision-making in transmission network planning and management

Abstract

Marine concrete is used for structures in marine environments that are susceptible to chemical attacks such as sulfates and chlorides. This study aims to analyze the effect of adding 7% silica fume on the compressive strength of marine concrete soaked in seawater. The experimental research method was carried out by making 12 concrete cylinder samples (diameter 15 cm × height 30 cm), consisting of two variations: concrete without silica fume and concrete with 7% silica fume. Compressive strength testing refers to SNI 03-1974-1990 and ASTM C39, with seawater immersion for 50 days and testing at the ages of 14, 28 and 50 days. The results showed that concrete with 7% silica fume achieved an average compressive strength of 39.90 MPa at the age of 28 days, higher than concrete without silica fume (37.64 MPa). This increase is due to the pozzolanic reaction of silica fume which fills the pores of the concrete and forms calcium silicate hydrate (CSH) compounds, increasing the density of the concrete matrix. The slump value of both concrete variations is stable at 12 cm, meeting the planned workability criteria. This study states that the addition of 7% silica fume is effective in increasing the compressive strength and resistance of marine concrete to the marine environment. Recommendations include the use of silica fume for marine structures, strict supervision in mixing materials, and optimization of mixing time to prevent too fast setting time. This study contributes to the development of environmentally friendly concrete with high durability in coastal areas.

Abstract

The use of additives originating from nature in the form of latex (rubber latex) and charcoal ash from coconut shells is expected to be a solution in improving the quality of road pavement. Latex (rubber latex) substitution of 1%, 2% and 3% and charcoal ash of 1%; 1.5%; and 2% were used in this research, with the aim of determining the effect of additives on asphalt properties values based on the 2018 Bina Marga Specifications. In the penetration test there was a decrease with an optimum substitution of 59.1 at a proportion of 2% latex and 1.5% charcoal ash. . In flash point and burn point tests, the addition of latex and charcoal ash caused the asphalt to heat up more quickly at lower temperatures than asphalt without additional ingredients. In testing the flash point and burning point, the optimum substitution was 1% latex and 1.5% charcoal ash. Meanwhile, in the ductility test, with the substitution of 1% latex and 1.5% charcoal ash, a ductility value of 105 mm was obtained. From several tests, it was concluded that the optimum substitution was for the 2% latex variant and 1.5% charcoal ash. These results meet the 2018 Bina Marga Specifications

Abstract

ABSTRACT Things that can influence soil to experience erosion include the nature of the distribution and erodibility of the soil. The level of soil erodibility is determined based on the structure, texture, permeability and organic matter content of the soil. The material tested in the pinhole testing in this case is clay material which will be used as embankment material for the Merauke PLTGM project, Papua. This test aims to classify whether the material is included in the dispersive (D) or nodisoercive (ND) clay category, while the aim is to determine the value of the erodobiolity coefficient K. This test uses the SNI-03-3405 method. What is observed in this test is the water discharge and turbidity of the water coming out of the testing equipment. From laboratory tests and analysis of the test results that have been carried out, the value of K = 0.19 is obtained, while the soil classification is in the D2 clay category. Keywords: diversive and Erodibility

Abstract

An important development in industrial automation is the combination of deep learning with cyber-physical systems (CPS), which allows systems to make data-driven, intelligent decisions with little assistance from humans. With an emphasis on its capacity to handle massive amounts of data for tasks including object detection, semantic segmentation, predictive maintenance, and autonomous control, this research investigates the revolutionary effects of deep learning on CPS. It looks at how technology has developed from early frameworks that relied on visual cues to complex systems that use cutting-edge neural networks that can function in dynamic, unstructured contexts. The study also emphasizes how important it is to integrate ethical frameworks, organizational preparedness, and human-centered design in order to successfully implement CPS. This study analyzes important trends, obstacles, and best practices that influence the application of deep learning in CPS through an extensive examination of recent literature. The significance of CPS in facilitating the Industry 4.0 and Industry 5.0 paradigms—which prioritize sustainability, human-machine collaboration, and real-time adaptation in industrial processes—is given particular attention.
