This study focuses on the development of an interactive web-based learning platform for Proportional-Integral-Derivative (PID) control systems, aimed at addressing the conceptual challenges faced by electrical engineering students when learning PID through conventional teaching methods. Despite its foundational role in control theory, PID remains difficult to grasp without practical visualization and hands-on experimentation. To bridge this gap, the research introduces a practical and accessible platform that enhances conceptual understanding through real-time simulations and physical interaction. The proposed system integrates key hardware components including an ESP-32 microcontroller, DC motor, rotary encoder, BTS 7960 motor driver, and I2C LCD. The platform’s web interface is built using HTML, Tailwind CSS, and JavaScript, enabling intuitive user interaction. Motor response data is captured via the ESP-32 and transmitted to the web interface using the WebSocket protocol, allowing users to instantly visualize system behavior as PID parameters (Kp, Ki, Kd) are adjusted. This dynamic feedback mechanism enables students to observe changes in system characteristics such as rise time, overshoot, and settling time in real time. To evaluate the platform’s feasibility, practicality, and educational effectiveness, beta testing was conducted among electrical engineering students using Likert-scale questionnaires. The results demonstrated that users were able to successfully interpret the impact of PID tuning on system performance. The average evaluation score reached 75.13%, indicating strong agreement regarding the platform’s educational value and its effectiveness in enhancing learning outcomes. In conclusion, the study affirms that the developed web-based platform offers a feasible, engaging, and pedagogically effective alternative to traditional learning approaches. By combining interactive simulations with physical experimentation, the platform significantly improves students’ understanding of PID control systems.

Profitability is one of the key indicators in assessing a company's ability to generate profits and plays a crucial role in financial decision-making. According to the pecking order theory, companies with high profitability tend to prefer using internal funds and reduce reliance on debt. This study aims to analyze the effect of profitability on debt policy, as well as to examine the role of dividend policy as a moderating variable in this relationship. The study employed Slovin’s formula for sample selection and analyzed 263 non-financial publicly listed companies on the Indonesia Stock Exchange (IDX) in 2023. The data used in this research were secondary data obtained from annual financial reports published on the official website of the IDX or the respective company websites. Profitability was measured using return on assets (ROA), debt policy was measured by the debt-to-equity ratio (DER), and dividend policy was measured by the dividend payout ratio (DPR). The analytical method used in this study was multiple linear regression analysis with the help of the SPSS software. The results indicate that profitability has a negative effect on debt policy, meaning that the more profitable a company is, the less likely it is to depend on debt financing. Additionally, the findings suggest that dividend policy does not significantly moderate the relationship between profitability and debt policy. This implies that whether a company distributes dividends or not does not meaningfully influence how profitability affects its debt decisions. These results are in line with the pecking order theory and provide insight for corporate financial managers in planning funding structures. It also emphasizes the importance of internally generated funds for companies with strong earnings performance.

Digital transformation in government bureaucracy has become a strategic step to improve efficiency, accountability, and transparency, including in the management of regional legal products.

Good Corporate Governance (GCG) refers to the practices and processes that guide a company's operations and decision-making, significantly influencing its financial performance. This study employs secondary and quantitative data, utilizing the Systematic Literature Review (SLR) method, with sources obtained from the Google Scholar website. The research focuses on the impact of the Independent Board of Commissioners, the Audit Committee, and Managerial Ownership on financial performance. The findings indicate that effective corporate governance, particularly the presence of an independent Board of Commissioners, positively influences financial performance as assessed by Return on Assets (ROA). Additionally, the Audit Committee is shown to have a significant and positive effect on financial performance. In contrast, while Managerial Ownership does not appear to impact financial performance when evaluated through ROA, it does exhibit a positive correlation when assessed using Tobin's Q. This suggests that higher managerial ownership can enhance market perceptions of the company's long-term value and stability. The study concludes that the successful implementation of Good Corporate Governance practices can lead to improved financial performance for companies. Conversely, inadequate execution of these governance principles may result in diminished financial performance and overall company value. Therefore, it is crucial for organizations to prioritize and effectively implement GCG to foster better financial outcomes and enhance their market standing. This research underscores the importance of governance structures in shaping financial results and highlights the need for companies to focus on governance practices to achieve sustainable growth and value creation. Ultimately, the study emphasizes that a strong commitment to GCG can lead to increased investor confidence and long-term success in the competitive business landscape.
