Abstract

Khusus nya di Daerah pedesaan  salah satu  kawasan  yang memerlukan listrik adalah konsep a hybrid energi  PLTA(Pembangkit listreik tenaga air ) dan PLTS (Pembangkit Listrik Tenaga Surya)  dengan  peralatan pembangkit energy listrik yang merubah cahaya matahari menjadi listrik. PLTS sering juga disebut sebagai solar cell, atau solar photovoltaic, atau solar energy. Dengan konsep sederhana yaitu mengubah cahaya matahari menjadi energy listrik yang mana cahaya matahari adalah salah satu bentuk energi dari sumber daya alam. Cahaya matahari sudah banyak digunakan untuk memasok daya listrik di satelit komunikasi melalui sel surya. Sel surya ini dapat menghasilkan energy yang tidak terbatas langsung di ambil dari matahari, tidak memerlukan bahan bakar sehingga sel surya sering dikatakan bersih dan ramah lingkungan.Untuk menambah daya listrik pada waktu diperlukan maka digabungkanlah kedua energi  PLTA dan PLTS dengan konsep Hybrid. Energy baru dan yang terbarukan mempunyai peran yang sangat penting dalam memenuhi kebutuhan energy, hal ini di sebabkan penggunaan bahan bakar untuk pembangkit-pembangkit listrik konvensional dalam jangka waktu yang panjang akan menguras sumber minyak bumi, gas dan batu bara yang makin menipis dan juga dapat mengakibatkan pencemaran lingkungan. Salah satunya upaya yang telah dikembangkan adalah pembangkit listrik tenaga surya. Pada penelitian  ini akan dibahas mengenai apa itu PLTS dan bagaimana apabila digabung dengan PLTA sesuai dengan kebutuhan.dan dengan adanya penelitian  ini diharapkan dapat memberikan pengetahuan mengenai PLTS  Hybrid dengan PLTA .

Abstract

Scholarship selection is a strategic process in higher education institutions that requires fairness, transparency, and objective decision-making. However, conventional selection methods often face challenges in handling multiple assessment criteria and large volumes of applicant data. This study proposes a Data-Driven Decision Support System (DSS) for scholarship selection in Deli Serdang Regency based on Multi-Criteria Analytics. The system integrates academic and non-academic indicators, including Grade Point Average (GPA), family income, academic achievements, organizational involvement, attendance records, and extracurricular activities. A quantitative approach was employed using student data collected from higher education institutions in Deli Serdang. Multi-criteria analysis was applied to evaluate and rank scholarship candidates according to predefined weighting schemes. The results demonstrate that the proposed system effectively identifies eligible candidates while improving consistency, transparency, and decision accuracy. Furthermore, the data-driven framework reduces subjective bias and supports evidence-based scholarship allocation. The study concludes that the proposed DSS can serve as a reliable tool for educational institutions and local governments in optimizing scholarship selection processes and promoting equitable access to educational opportunities.

Abstract

The use of unbalanced electrical loads in power systems can significantly impact the lifespan of electrical equipment. Load imbalance often occurs in power distribution systems serving various types of consumers with diverse consumption patterns. This study aims to analyze the effect of unbalanced load usage on the lifespan of electrical equipment, such as transformers, cables, and protection devices. The methodology involves measuring electrical parameters such as current, voltage, and power factor under balanced and unbalanced load conditions. Operational data are processed to determine the level of imbalance and its effects on temperature rise, power losses, and equipment efficiency degradation. The analysis is complemented with simulation models to predict equipment lifespan reduction based on thermal and electrical standards. The results indicate that load imbalance leads to a significant increase in operating temperatures, particularly in transformers and cables, accelerating insulation degradation. Additionally, load imbalance increases power losses, reducing overall system efficiency. This study concludes that better load management to achieve balance can extend the lifespan of electrical equipment and improve the reliability of power systems.

Abstract

The reliability of the electric power transmission system is a crucial factor in ensuring the continuity of electrical energy distribution to customers. Disturbances in the transmission system can cause significant technical and economic losses. Therefore, the application of Adaptive Defense Schemes (ADS) was developed as an effort to improve the performance of the protection system and the reliability of the electric power transmission system. This study aims to analyze the performance of ADS on the Barikin-Tanjung bay line electric power transmission system and evaluate its technical and economic effectiveness. The disturbance data used include the number of disturbances, the duration of disturbances, and Energy Not Supplied (ENS) during the period 2015–2022, which is divided into the pre-implementation period of ADS (2015–2018) and post-implementation period of ADS (2019–2022). The Autoregressive Integrated Moving Average (ARIMA) method is used to analyze the characteristics of time series data and forecast disturbances in the period 2023–2026. The results of the analysis show that the implementation of ADS is able to reduce the number of disturbances, the duration of disturbances, and the ENS value significantly in the post-implementation period. The selected ARIMA models, namely ARIMA (2,1,1) for the number of disturbances, ARIMA (3,1,1) for the duration of disturbances, and ARIMA (2,1,1) for ENS, produced stable predictions with residuals without significant autocorrelation. In addition, the results of the economic analysis showed that the implementation of ADS was able to reduce the company's potential losses by more than 50% compared to the scenario without ADS. Thus, ADS has proven effective in improving the reliability of the electric power transmission system and is worthy of being recommended for implementation in other transmission lines with high levels of vulnerability.

PPF installation requires optimal temperature conditions (20-27°C) to ensure proper adhesion, but workshop environments often experience temperature fluctuations that compromise installation quality. The research method uses computational simulation with a modified Mamdani fuzzy logic approach, incorporating more aggressive membership functions, adaptive aggression factors, and integral control. Simulation was conducted with a setpoint of 20°C, initial temperature of 30°C, and duration of 30 minutes. Results show the system successfully achieved a steady-state error of 1.491°C, overshoot of 45.14%, and settling time of 30.0 minutes, meeting validation criteria with steady-state error < 1.5°C. The system maintained temperature within the manufacturer-recommended range for PPF installation. The research concludes that modified fuzzy logic control strategies effectively enhance system performance for specific PPF workshop applications. The main contribution is the development of a control system tailored to the specific requirements of PPF workshop environments, filling a research gap in intelligent control system applications for this context.

Abstract

The rapid advancement of portable electronic device technology, particularly laptops, necessitates a charging solution that is faster, more efficient, and compatible with diverse standards. The USB-C Power Delivery (USB-C PD) protocol has emerged as a universal charging standard due to its ability to support flexible voltage and current configurations. Nevertheless, the overall charging efficiency remains constrained by dynamic load behaviour, fluctuations in power sources, and the limitations of conventional power management techniques. This paper described the integration of a Maximum Power Point Tracking (MPPT) algorithm into a USB-C PD-based fast-charging system for laptops, aiming to enhance energy transfer efficiency between the power source and the device. The research methodology involves the design and simulation of a power management system incorporating MPPT, hardware prototyping, and performance evaluation based on efficiency, charging duration, and voltage stability metrics. Experimental results indicate that the implementation of the MPPT algorithm significantly improves charging efficiency, minimizes energy losses, and reduces charging time compared to conventional charging methods. The proposed approach not only contributes to the advancement of USB-C PD-based fast-charge technologies but also lays a foundation for future developments in intelligent, energy-efficient power management systems. These findings have broad potential applications in next-generation electronic devices that demand fast, adaptive, and sustainable charging solutions.
