An effective learning process in the classroom involves increasing the ability to understand and apply concepts. Learning strategies play a crucial role in realizing this goal, becoming the main focus in efforts to improve the quality of education. The goals of modern education involve developing the ability to understand and apply concepts, producing individuals who are not only skilled in knowledge but also able to apply these skills in everyday life. In addition, the application of knowledge becomes essential, where learning is not only about receiving information but also about the ability to apply knowledge in real contexts. Learning strategies that focus on application help students develop practical skills that can be used in a variety of situations. Analysis of learning strategies is carried out by considering their relevance to the curriculum and support for learning styles. Relevant research results from 12 articles have been analyzed to gain an in-depth understanding of the most effective learning strategies. Based on the results of the analysis, several learning models such as Conceptual Understanding Procedures, Teams Games Tournament, and Blended Learning have been proven to be effective in increasing concept understanding. This research highlights the role of learning strategies in improving the ability to understand and apply concepts at the educational level.

Education in elementary schools has the aim of helping students understand problems in everyday life. The national education system states that education aims to develop the potential of students to become human beings who have faith, noble character, health, knowledge and responsibility. In the context of mathematics education, the PMRI (Indonesian Realistic Mathematics Education) approach is used to help students understand mathematical concepts through real experiences and the context of everyday life. The data grouping learning trajectory using the PMRI approach aims to help grade 1 elementary school students understand the concept of data grouping. The use of sorting and choosing props can also improve the learning outcomes of low grade students in sorting and selecting certain objects or concepts. The aim of this research is that it is hoped that students can learn more effectively through direct experience, visualization and physical movements involved in the sorting and choosing process. Data was collected through interviews and tests. Based on the results and discussion of the research that has been conducted, it can be concluded that the design of a data grouping learning trajectory for elementary school students using an Indonesian realistic mathematics education approach is theoretically able to provide a deeper understanding of data grouping for grade I elementary school students. With the principles in PMRI, students are given the opportunity to develop a conceptual understanding of data grouping with the help of the images provided.

The science fiction novel "Only Human" by Sylvain Neuvel summarizes the journey of humans and artificial intelligence (AI) in interacting with alien creatures on a mysterious planet. This research uses a hermeneutic method to deepen understanding of the story context. The main focus of research is the character of AI, Technology, Robots and Aliens which play a central role in facilitating communication between humans and aliens. In this case it explores how the presence of AI supports human efforts to understand very alien culture and technology. In the process of analysis, we also explore the ethical and moral aspects that arise along with the use of AI in the context of intersex relationships. With a hermeneutic method, highlighting how contextual interpretation and understanding enriches the analysis of the complex dynamics between humans, AI, and aliens. This research provides in-depth insight into the concepts of artificial intelligence, technology, robots, and aliens in the narrative "Only Human," which is expected to stimulate further thinking about the future of human interaction with artificial intelligence and extraterrestrial life.

Good Corporate Governance is the most well-known principle in the world for maintaining the integrity of world organizations. Almost all international locations in all countries adhere to the foundation of building responsibility and openness. Unfortunately, in its application, GCG does not explain the values ​​of stakeholders. The study aims to reconstruct GCG (OECD version) and look for a more appropriate Sharia Concept. Of course, this will provide a solution to the problem itself. After analyzing the values ​​and character of SET, we built a modern GCG positioned on Islamic concepts. These concepts are; One; deeper sympathy from stakeholders, second; principles regarding stakeholder rights: third, equality in stakeholder behavior, fourth, the principle of openness, finally, regarding corporate accountability.Weak GCG practices in Indonesia are caused by the low level of protection for investors, law enforcement, transparency and ineffective public company audit committees. This condition strongly encourages the need for effective and efficient global corporate governance. Islamic Corporate Governance The Islamic perspective lies in the Islamic Company Theory which has greater concern for wider stakeholders which include God, humans and nature. The difference in goals between conventional Corporate Governance and Sharia GCG which tends to adhere to Sharia Enterprise Theory (SET). SET equates material and spiritual values. This shows that Sharia GCG does not only achieve material benefits, but also spiritual values. SET also equates egoistic values ​​with altruistic values, which in Islamic law are realized in the form of worship.
