This paper presents an IoT-enabled dual-axis solar tracking system that integrates  a Kalman filter and a Proportional-Integral-Derivative (PID) controller to enhance tracking accuracy, energy efficiency, and operational stability. Addressing the ongoing challenge of maxi- mizing photovoltaic (PV) panel output, the proposed system leverages an ESP32 microcontroller and the Blynk platform to provide real-time monitoring, remote parameter adjustments, and flexible connectivity. Light Dependent Resistor (LDR) sensors measure sunlight intensity from multiple directions, while MG90S servo motors dynamically adjust the panel’s azimuth and elevation. The Kalman filter refines noisy sensor data to yield precise sun position estimates, enabling the PID controller to respond quickly and accurately to deviations in panel orientation. Through extensive testing conducted over several days, including both clear and partially cloudy conditions, the system achieved an average Root Mean Square Error (RMSE) as low as 1.2° under clear skies and maintained RMSE below 2.0° even under partial shading. Compared to a fixed-panel baseline, daily energy harvesting improved by approximately 43%. These results confirm that advanced estimation and control algorithms, when combined with IoT functionali- ties, significantly outperform simpler tracking methods and static installations. Furthermore, the low-cost, compact design and user-friendly interface facilitate practical deployment in a range of scenarios, including small-scale and off-grid installations. By ensuring continuous alignment of the PV panel with the sun, the system not only increases overall energy capture but also reduces maintenance requirements through remote oversight. This research thus offers a robust, scalable approach to improving solar energy utilization in diverse and evolving environmental conditions.

Oil production from a reservoir will naturally decrease or even not be able to produce at all. This condition does not necessarily indicate that the oil reserves in the reservoir have run out. If we only rely on primary production methods (primary recovery), it is likely that there is still a lot of oil left in the reservoir, so advanced production methods are needed to be able to drain the oil that is still left in the reservoir. Advanced oil recovery technology or Enhanced Oil Recovery (EOR) continues to develop to overcome the challenges in increasing oil production from reservoirs that have entered the secondary or tertiary production stage. One method that has attracted attention is Miscible Gas Flooding (MGF), which involves injecting certain gases into the reservoir. This method allows the creation of perfect mixing conditions (miscible) between the injected gas and the oil in the reservoir, thereby increasing the efficiency of oil transfer and maximizing recovery results. This technology is a solution to maximize the potential of oil wells that have experienced decreased productivity. The main principle of Miscible Gas Flooding is to reduce the interfacial tension between oil and gas, and reduce the viscosity of the oil, so that the oil can flow more easily to the production well. Commonly used gases include carbon dioxide (CO₂), nitrogen (N₂), or light hydrocarbons such as methane and ethane. With the right pressure and temperature, these gases can mix homogeneously with oil, resulting in higher displacement efficiency compared to water or immiscible gas injection methods. These advantages make MGF one of the most effective approaches to increase oil well productivity in complex reservoirs. Although promising, the implementation of Miscible Gas Flooding requires careful planning and a comprehensive evaluation of reservoir conditions. Factors such as the minimum pressure to achieve miscibility, the type of gas used, and potential disturbances such as fingering or channeling must be carefully considered. In addition, operational costs and the infrastructure required are also aspects that need to be taken into account.

This study aims to analyze the effect of the Debt to Equity Ratio (DER) on the Net Profit Margin (NPM) of PT Astra International Tbk, listed on the Indonesia Stock Exchange (IDX) during the 2021–2023 period. This research employs a descriptive quantitative approach using secondary data obtained from the company's annual financial reports. Data analysis techniques include descriptive analysis, Pearson correlation test, and simple linear regression. The results show a negative relationship between DER and NPM, with a correlation coefficient of -0.726, indicating that an increase in DER tends to be followed by a decrease in NPM. However, this relationship is not statistically significant, with a p-value of 0.483. Regression analysis results reveal that DER can only explain 52.7% of the variation in NPM, while the remaining percentage is influenced by other variables outside this research model. Therefore, although capital structure plays a role in influencing profitability, other factors such as operational efficiency and cost management also need to be considered to improve the company's financial performance.
