Education plays an important role in the progress of a nation, the high number of Islamic communities in Indonesia, including in Deli Serdang Regency, can be ensured that Muslims in Indonesia have an important role in the progress of a nation. Professor Toshiko Kinosita stated that Indonesia's human resources are still very weak to support industrial and economic development, the reason is because the government has never placed education as the most important priority, there are still various education problems that have not been resolved, such as limited education funds. , shortage of teaching materials, low number of skilled teaching staff, and inadequate facilities. To advance the nation's education, development is needed both in terms of physical and learning methods. Therefore, one effective solution is to build a Tahfidz Islamic Boarding School based on General Education. The development of science requires society to choose between focusing on knowledge in the field of religion or academics in general. Often people dream of mastering balanced knowledge, but many schools only focus education on one scientific field and reduce the quota in other fields so that knowledge becomes unbalanced. Tahfidz Islamic Boarding School is designed to provide knowledge and comfort in the learning process, equipped with adequate facilities and infrastructure as well as a more aesthetic building shape. This research aims to analyze the challenges and obstacles in developing the Tahfidz Islamic Boarding School based on General Education, and develop an inclusive and friendly solution environment. The focus is on meeting the needs of varying user capabilities, while ensuring good accessibility and sustainability. In the design, building design innovations are also proposed to achieve this goal, taking into account aesthetics and Islamic values ​​in accordance with the function of the building. The methods used include mixed qualitative methods with observation, comparative studies, case studies, interviews and document analysis. The building which applies Islamic architectural concepts in the design of the Tahfidz Islamic Boarding School will also consider Islamic aesthetics and values ​​in its application.  

This study aims to explore the application of GeoGebra software in improving students' mathematical communication skills.

This research explores the representation of fear in the context of leaving Batak culture as depicted in the film "Ngeri-Ngeri Sedap". Through a content analysis approach, this study investigates how the fear associated with leaving cultural identity is reflected in the narrative, visuals, and characters in the film. Qualitative methods are used to analyze various film elements, including dialogue, plot, setting, and cultural symbolism. The findings indicate that the film portrays the complexity of fear experienced by individuals confronted with the conflict between tradition and modernity. These representations provide insights into the cultural dynamics within Batak society and their implications for individual identity. The study contributes to understanding how fear is associated with cultural change and how it is reflected using Roland Barthes' semiotic analysis framework. The goal of this study is to use Roland Barthes' semiotic analysis method to uncover the moral lessons that are subtly conveyed in films.  The study uses qualitative descriptive methodologies and centers on specific cinema moments.  While connotation is investigated to uncover the hidden meaning behind these indicators, denotation is used to identify signs as they seem on the surface.  Myth analysis is another method used in this research to find concepts that are implied by the movie's plot.  Through the use of Roland Barthes' semiotic approach, the study unveils "Ngeri-Ngeri Sedap"'s intricate and multilayered narrative structure. The research findings offer profound insights into the ways in which the film uses verbal and visual cues to convey moral lessons to its audience.  This study enhances our knowledge of semiotic analysis in the context of film by shedding light on symbolic representations and hidden messages in audiovisual art.

This research aims to provide an explanation related to the basic concepts in the development of cost behavior, which is viewed from theoretical and practical cost behavior. The aim of writing this article is to provide a comprehensive picture of cost behavior towards fixed costs. It is hoped that the results of this research can be used by management in estimating more accurate production costs. For academics, this paper is useful for increasing insight and bringing theoretical concepts closer to a practical level. This research reviews the nature of cost behavior by examining the relationship between total costs and changes in cost drivers, which exist in manufacturing companies. Based on the discussion in this research, basically the nature of cost behavior can be grouped into two, namely fixed and variable. Fixed costs have the characteristic that the total costs remain the same, even though the cost drivers change. Meanwhile, variable costs are characterized by total costs that change proportionally to changes in the cost driver.

The learning process of students can be assessed through evaluation methods. The purpose of this evaluation is to assess learning outcomes as well as to evaluate the learning process. The concept of learning evaluation involves the control, assurance, and establishment of learning quality for all components at various levels and pathways of education, which is the responsibility of educational management. Assessment is the process of using various methods and tools to collect information about specific learning outcomes. Measurement, in English, refers to an action taken to adjust something. The basic way of measuring is by comparing something to a certain standard. Educators provide a series of tasks or questions to students to gauge their understanding and reach an agreement between students and teachers regarding the taught material, in line with current learning objectives, commonly referred to as tests. Therefore, it can be concluded from the table that tests are a benchmark for success in delivering education through educational assessment.

The purpose of this study is to understand the extent to which fasting material is taught in class VIII junior high school. This research uses the literature study method, in which data is collected from the fiqh teacher's book and student book in the class. The data obtained were then analysed and presented. The results showed that the material on fasting in the fiqh textbooks of grade VIII students was still lacking in depth and breadth. Therefore, it is expected that teachers can enrich the material taught by considering facts, concepts, principles, and procedures that must be clear, functional, valuable, and easy to understand. This step is taken to ensure that students not only know the development of science and technology but can also balance it with the religious knowledge they learn. It is hoped that the research activities that include the revision and development of fiqh subject matter will yield positive results. The new fiqh materials are expected to be more weighty, effective, and easier to understand by both teachers and students.
