Renewable energy systems, particularly those incorporating solar and wind power, are prone to stability issues due to the intermittent and fluctuating nature of these energy sources. This paper investigates several nonlinear control techniques—namely, adaptive control, sliding mode control, and fuzzy logic control—that are designed to improve stability in renewable energy systems. Through simulations, we demonstrate how these methods can effectively reduce fluctuations and maintain stable energy output, offering a robust approach to enhancing the reliability of renewable energy systems.

This study focuses on how the portrayal of female power in one of Disney's films, Mulan. Film can provide a construct in socio-cultural reality. With this construction, the content of the film needs to be considered, because the content of the film can change the mindset of the audience who watches. Women are usually often complementary figures and do not have dominance than men. This is an interesting study because women can be constructed with the image above. Therefore, researchers dissect the portrayal of female power presented by Disney. Researchers use Ferdinand De Sausure's semiotic analysis method which focuses on signifiers and signified in interpreting women's power in Mulan. The supporting theory in this study is film as mass communication and women in the media. The results of the study showed three depictions of female strength from the film Mulan, namely women who are brave, women who resist and women who has a confident nature.

This article aims to describe the implementation of the Madrasah Education Section's Educator and Education Personnel Management Information System (SIMPATIKA) at the Palangka Raya City Office of the Ministry of Religious Affairs. The main focus in this research includes: implementation, effectiveness of use, and inhibiting factors of SIMPATIKA implementation. This research was conducted qualitatively with data collection through in-depth interviews, observation, and documentation. The results showed that: 1) The implementation of SIMPATIKA has been carried out by the Madrasah Education Section at the Palangka Raya City Ministry of Religious Affairs Office, which is managed by SIMPATIKA Special operators.2) The effectiveness of using SIMPATIKA as a madrasah data management system has not been fully realized.3) The inhibiting factors of SIMPATIKA implementation are mainly caused by the ignorance of some teachers in accessing the management information system for educators and education personnel (PTK). This has led to the delegation of SIMPATIKA account management to madrasah operators, whereas the account should be managed individually by each educator. The proposed solution is to hold technical guidance on the SIMPATIKA management information system, and provide an understanding of the rights and responsibilities in using individual SIMPATIKA accounts..

Early childhood plays an important role in forming the basis of development, which involves stimulation of various aspects such as moral religious values, social emotional, language, cognitive, and physical motor skills. The concept of early childhood learning is focused on play, where every activity is designed to be play, so that learning becomes more effective. Parents also need to understand today's children's education to interact with children positively. This research focuses on sentiment analysis of children's education-based app reviews on the Google Play Store, using Random Forest and Logistic Regression methods. The review data is taken from three apps with the theme of child development, namely "About Kids", "PrimaKu", and "Teman Bumil", with a range of review years between 2018 and 2023. The test results show that Logistic Regression has higher accuracy compared to Random Forest, especially in the "About Kids" and "PrimaKu" applications with accuracy above 90%. The conclusion of this research highlights the importance of sentiment analysis in improving understanding of user responses to children's education applications, with suggestions for future research to increase the number of datasets and variations in testing schemes by tuning hyperparameters to improve prediction accuracy and more optimal results.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in the economy by creating jobs and fostering local economic growth. However, MSMEs, especially in the culinary sector, often face challenges in managing finances, including accurately calculating the Cost of Goods Manufactured (COGM). COGM, which includes raw materials, labor, and overhead costs, is essential for setting appropriate prices and maintaining profitability. Miscalculations can lead to inaccurate pricing, impacting competitiveness and profit margins. This study analyzes COGM calculations at U&Mie, a culinary MSME known for its chili oil chicken noodles, to understand its pricing strategy. Findings from this research and prior studies by Harefa and Purwanto reveal that the full-costing method provides consistent results, highlighting the need for comprehensive COGM calculations to avoid overlooking variables that could affect pricing. This study aims to offer guidance for MSMEs in managing production costs and setting prices effectively, enhancing their market competitiveness.

Customer segmentation plays a pivotal role in driving marketing strategies and improving customer retention across various industries. This study explores the application of the RFM (Recency, Frequency, Monetary) model for customer segmentation in a Software-as-a-Service (SaaS) business, using Python for efficient data processing and analysis. By analyzing one year of customer purchase data, we segmented customers into key groups such as "Champions," "Loyal Customers," and "At Risk." The results highlight that targeted discount strategies significantly affect profitability, especially for high-value customer segments. Furthermore, the research builds upon existing methodologies, demonstrating how Python-based implementations streamline RFM analysis and allow for scalable solutions in business contexts, as illustrated in prior works by Hermawan et al. (2024). This study offers actionable recommendations, including tailored discounting, loyalty programs, and personalized engagement strategies, to enhance customer retention and business profitability. The findings underscore the importance of data-driven marketing approaches for customer segmentation and engagement, reinforcing the relevance of the RFM model in modern business environments.

This study examined the allocation of financial aid funds from the Banda Aceh Regional Government Budget (APBK) to Local Political Parties X and Y in Banda Aceh. This study conducted empirical juridical research and presented the findings of field research using two analytical frameworks: Legal Effectiveness theory and Siyasah Maliyah Fiqh theory. It focused on local political parties since they represent a unique kind of democracy in the Aceh region. From the standpoint of legal effectiveness theory, the findings of this study suggest that the supporting facilities in the form of financial aid and legal factors are adequate and suitable. Nevertheless, barriers remain present within law enforcement, society, and culture. From the accumulated results of the components of the theory of legal effectiveness, a fiqh siyasah maliyah perspective is obtained. Thus, it can be concluded that the principles of ownership and management are still hampered by transparency, accountability, and openness of information to the community. The principle of abuse and corruption is already working well, but the accuracy of targeting financial funds must be improved The people's benefit has not been completely realized as a result of the aid use not being targeted.. The principle of amar ma'ruf nahyi mungkar has also not been fully implemented because it is hampered by a crisis of public trust, the party's understanding of regulations, and the infrastructure supporting transparency and accountability.
