Set theory is one of the fundamental concepts underlying the structure of discrete mathematics and computer science and plays a crucial role in understanding various advanced topics, such as relations, functions, mathematical logic, and other discrete structures. This concept serves as the foundation for developing a systematic and structured mathematical mindset. This paper aims to explain the fundamental concepts of set theory, review its significance in discrete mathematics, and outline how to present sets and basic operations on sets, such as union, intersection, complement, and difference. The method used in this paper is a literature study by reviewing, collecting, reading, and analyzing data from various relevant written sources, both textbooks and scientific articles. Through this study, students are expected to be able to understand set theory more comprehensively. Thus, it can be concluded that set theory is not merely an introductory topic, but rather a formal framework that defines the validity of logic and structure in modern discrete systems.  

In this study, a device was designed and implemented to control the water pH and nutrient density (concentration) in a hydroponic system using the Mamdani method of fuzzy logic, thus maintaining nutrient solution parameters within an optimal range for plant growth. This system relies on three input values ​​obtained from a water pH sensor, a nutrient TDS sensor, and a flow meter. These three sensors are used to control four peristaltic motors, each of which functions to increase and decrease the pH and nutrient levels in the solution. The speed of the peristaltic pump motor, when the water pH is set at 6.5 and the nutrient concentration is set at 700 ppm, is influenced by the difference between the sensor reading and the set point. The greater the difference, the higher the peristaltic pump motor speed. Conversely, the smaller the difference between the sensor reading and the set point, the lower the peristaltic pump motor speed. Furthermore, the amount of water flowing through the pipe also influences the peristaltic pump motor speed.

Science lessons in primary school significantly contribute to the early development of logical, scientific and systematic reasoning skills.   However, learning science can be challenging, especially when it comes to understanding abstract concepts and cause-and-effect interactions.   This is due to the fact that, as per Piaget's theory, primary school students are still in the concrete operational stage and have limited cognitive growth. Data regarding abstraction ability and causal reasoning in the context of science education were collected from various scientific sources using the literature review research methodology.  According to the research findings, STEAM integration, project-based learning strategies such as Project Based Learning (PBL), and the use of real and visual aids can help lower learning barriers. Successful learning is also influenced by the teacher's role as facilitator, which involves presenting the material in a relevant and contextualized way and fostering a positive learning environment. Real-world examples and exceptional examples, such as the use of worksheets based on cause-and-effect relationships and basic experiments, demonstrate how useful these strategies are for improving abstract thinking and understanding of cause-and-effect relationships. Developing innovative teaching methods based on practical, exploratory and integrative experiments is essential for maximizing the scientific understanding of primary school students.

Learning is the process of children getting to know knowledge that aims to increase knowledge as a basis for forming behavior. The learning process is carried out so that children experience behavioral changes and gain an overall improvement in knowledge, skills, and attitudes. Learning is very closely related to daily life, therefore it is important for children to learn continuously, one of which is through learning mathematics. Mathematics learning has a very important role in the sustainability of children's education because mathematics is one of the fundamental non-physical tools in the world of education and daily life. Through mathematics learning, children are trained to think logically, systematically, critically, and creatively in solving various problems. In addition, mathematics helps children solve calculation problems that are often encountered in daily activities, such as counting money, measuring length, time, and distance, and interpreting simple data. Mathematics learning also plays a role in developing the ability to reason and make appropriate decisions. Therefore, mathematics learning is a subject that must be followed because it has a great influence on thinking skills, learning independence, and children's readiness to face life challenges and scientific development in the future.

Aceh Tamiang Regency is an area with a high risk of annual flooding. This emergency condition often triggers a surge in environment-related diseases such as skin diseases, respiratory infections, and diarrhea. The success of managing health crises heavily depends on pharmaceutical logistics management, especially the availability of essential medicines and ease of access for refugees at evacuation points. This study aims to analyze the extent of medicine availability at community health centers and health posts, as well as to evaluate the barriers to medicine accessibility for flood victims in Aceh Tamiang Regency. This study uses a qualitative/quantitative descriptive method (choose one) with a case study approach. Primary data were collected through in-depth interviews with pharmaceutical logistics officers and surveys of flood survivors. Secondary data were obtained from the drug stock reports of the Aceh Tamiang District Health Office. Analysis was conducted on variables such as drug types, stock amounts (Buffer Stock), and distribution channels during the emergency response period. The results of the study indicate that the availability of drugs in the initial disaster phase tends to be (state the prediction, e.g., sufficient/limited). However, accessibility is often hindered by damaged road infrastructure and uneven distribution to remote posts. There is an urgent need to strengthen the logistics early warning system so that the types of medicines available match the disease patterns that emerge after floods. Although medicine stocks are generally available in central pharmacy warehouses, geographical constraints and distribution coordination are the main factors hindering accessibility. It is recommended that local governments map out alternative distribution routes and provide disaster-specific buffer stock of medicines at the sub-district level.

Senior high school students represent a strategic age group transitioning into adulthood and are expected to become future leaders of the nation. In the context of achieving Indonesia’s Vision 2045, threats to national resilience are no longer dominated by military aggression, but rather by non-military challenges in the form of cognitive warfare. One prominent manifestation of this threat is the massive exposure of students to low-value digital content, commonly referred to as brain rot, on social media platforms. Such content has the potential to reduce attention span, critical thinking ability, and national awareness among adolescents. Consequently, senior high school students have become a vulnerable group in the spread of misinformation, disinformation, and ideologies that contradict Pancasila values. This community service activity aims to provide training and strengthen national defense character (bela negara) among senior high school students in Jakarta through an educational and participatory approach. The methods employed include the delivery of conceptual materials on national defense awareness and digital literacy, as well as national defense debate simulations designed to enhance students’ critical, argumentative, and ethical thinking skills. The results indicate an improvement in participants’ understanding of national defense values and their ability to express logical and responsible arguments. This activity is expected to contribute to the development of a resilient, critical, and nationally-minded young generation capable of facing contemporary challenges in the digital era.

Flood disasters are recurring hydrometeorological hazards that significantly impact social, economic, and environmental conditions in Tulungagung Regency. This study aims to analyze the flood disaster mitigation communication strategies implemented by the Regional Disaster Management Agency (BPBD) of Tulungagung Regency and to identify the roles, challenges, and implications of both internal and external communication in flood disaster management. The research employed a qualitative approach using a descriptive method. Data were collected through in-depth interviews with the Secretary of BPBD Tulungagung Regency, the Head of the Emergency and Logistics Division, the Head of the Prevention and Preparedness Division, and members of flood-affected communities. The findings reveal that BPBD Tulungagung Regency has attempted to optimize disaster communication during the pre-disaster, emergency response, and post-disaster phases. The effectiveness of these communication efforts remains limited due to several challenges, including inadequate communication infrastructure, varying levels of disaster literacy among community members, diverse geographical conditions, and insufficient coordination in internal and external communication. Pre-disaster communication plays an essential role in improving community preparedness, communication during emergency response supports timely and accurate decision-making, and post-disaster communication contributes to recovery processes and the strengthening of community resilience. This study concludes that optimizing disaster communication requires integrated information systems, improved human resource capacity within BPBD, and active community participation through community-based communication approaches to sustainably enhance resilience to flood risks.

The rapid development of digital technology highlights the importance of introducing computational thinking skills from an early age, including at the elementary school level. One effective approach to introducing basic programming concepts is through block-based coding learning media that are visual, interactive, and engaging. This community service activity aimed to improve elementary school students’ understanding and interest in basic coding through hands-on training using block-based coding media. The program was implemented with sixth-grade students at Yayasan Kemala Bhayangkari 1 Medan. The activity employed a hands-on training approach consisting of several stages, including an introduction to basic coding concepts, familiarization with the Blockly Games interface, and practical exercises involving puzzle and maze challenges designed to develop logical thinking, sequencing, and problem-solving skills. The evaluation was conducted through direct observation of student participation and assessment of students’ ability to complete the given challenges. The results demonstrated that the use of Blockly Games effectively increased students’ enthusiasm, active engagement, and understanding of basic programming logic. Students who initially perceived programming as difficult showed greater interest and confidence due to the colorful, visual block-based instructions that were easy to understand and enjoyable. This community service activity is expected to serve as an effective introductory model for coding education and to support the development of digital literacy among elementary school students.

Human–Robot Interaction (HRI) systems increasingly rely on data-driven approaches to interpret multimodal sensory inputs and support natural interaction. However, purely neural-based HRI models often suffer from limited interpretability and insufficient context-aware decision-making, which can reduce user trust and adaptability in dynamic interaction scenarios. To address these limitations, this study proposes a hybrid neural–symbolic HRI framework that integrates multimodal neural perception with explicit symbolic reasoning for adaptive and interpretable robot behavior. The proposed system combines deep neural networks for processing visual, speech, and gesture inputs with a rule-based symbolic reasoning layer that models interaction context, user states, and behavioral constraints. A loosely coupled integration strategy enables neural outputs to be transformed into symbolic representations, allowing logical inference to guide action selection while preserving perceptual accuracy. The framework was evaluated through controlled HRI experiments comparing a neural-only baseline with the proposed hybrid configuration across multiple interaction scenarios. Experimental results demonstrate that the hybrid neural–symbolic system significantly improves interaction accuracy, contextual responsiveness, and user satisfaction, while achieving substantial gains in interpretability. These findings indicate that symbolic reasoning effectively complements neural perception by enhancing transparency and context-aware adaptation without compromising performance. The study concludes that hybrid neural–symbolic architectures provide a promising foundation for developing trustworthy, adaptive, and human-centered HRI systems.

This study aims to analyze the effectiveness of enforcement actions undertaken by the Business Competition Supervisory Commission (KPPU) in Indonesia in 2025 against various forms of unfair business practices. Using a juridical-normative approach combined with an analysis of recent market data, this article examines the KPPU’s strategic response to the challenges posed by the digital economy. The study focuses on the enforcement of competition law against cartel practices, algorithmic collusion, abuse of dominant positions, and anticompetitive vertical integration, particularly in the logistics and food sectors. The findings indicate that 2025 marks a significant turning point in Indonesian competition law enforcement, characterized by a shift toward more aggressive and data-driven supervision. Strengthening enforcement authority, particularly in the execution of fines, along with the adoption of algorithmic audits, has enhanced the KPPU’s ability to detect and deter anticompetitive behavior. These measures aim not only to preserve market efficiency and fair competition but also to ensure that national economic growth is not concentrated among a small number of dominant firms, thereby promoting more equitable opportunities for micro, small, and medium enterprises (MSMEs).

This research examines law enforcement against immigration violations and the factors influencing the effectiveness of border crossing inspection at the Immigration Checkpoint (TPI) of Tanjung Perak, Surabaya. Immigration inspection plays a vital role in safeguarding national sovereignty and monitoring cross-border human movement. Using a normative juridical approach with statutory and conceptual approaches, the findings demonstrate that enforcement procedures include document verification, identification of violations, administrative actions, and deportation in accordance with Law Number 6 of 2011 concerning Immigration. Common violations found include misuse of stay permits, travel document forgery, unauthorized border crossers, and illegal activities by foreign nationals beyond visa provisions. However, implementation still faces challenges such as limited human resources, inadequate infrastructure, and weak inter-agency coordination. Several factors affect the effectiveness of inspections, including personnel quality, technological support, legal frameworks, infrastructure capacity, traveler volume, inter-agency cooperation, political and international relations factors, socio-cultural dynamics, financial and logistical support, as well as internal supervision and accountability systems. The research concludes that institutional capacity building, policy integration, regulatory harmonization, and strengthened internal supervision are essential to ensure optimal immigration control at TPI Tanjung Perak in facing global challenges.

The Scientific Writing course plays an important role in equipping students with academic skills, particularly in developing systematic and scientifically sound research methodology.

This study traces the historical and intellectual processes that enabled Plato's ideas to enter the tradition of Islamic philosophy and subsequently influence Islamic boarding school education in Indonesia. Starting from the increasing openness of Islamic boarding schools to classical humanities, this study aims to understand how Plato's ideas were transferred from the context of Ancient Greece, reinterpreted by Muslim philosophers, and integrated into traditional learning practices. Using a library-based qualitative approach with hermeneutic, historical-intellectual, and thematic methods, this study analyzes the transmission pathways that include the Abbasid translation movement, the interpretive contributions of figures such as Al-Kindi, Al-Farabi, and Ibn Sina, and the absorption of concepts through literature on ethics, logic, and adab. The findings show that Islamic boarding schools did not inherit Plato's ideas directly, but rather through the Islamic philosophical tradition that reshaped Platonic elements to fit the Islamic intellectual framework. Concepts related to spiritual education, character building, and ethical rationality are in line with the orientation of tazkiyah al-nafs, which is the foundation of Islamic boarding school pedagogy. This study confirms that the relationship between Plato's ideas and Islamic education emerged through a long creative process, not merely a transfer of texts. Practically, these findings highlight opportunities to develop a more reflective, critical, and virtue-centered pesantren curriculum, while encouraging further ethnographic research to explore how the classical philosophical heritage is reinterpreted in contemporary santri learning practices.

Higher education in Indonesia has undergone significant transformation due to the implementation of a capitalist system that emphasizes profit orientation and business logic. The commercialization of educational institutions has resulted in limited access, particularly for low- and middle-income communities, and has led to social inequality and a shift in the educational paradigm toward commodification. This study uses qualitative methods with literature review to examine the impact of capitalism and commercialization in higher education. The findings reveal an increase in tuition fees, the commodification of knowledge, and the privatization of universities, which reduce access and lower the quality of education. Criticism of educational capitalism emphasizes the importance of social and spiritual values and equal access. Therefore, it is recommended that policy reforms balance the roles of the state and the private sector, strengthen regulations, and expand access to fair and quality education for the sake of higher education that is oriented towards social welfare and sustainability.

This research examines the practices of a B4 class teacher at RA Takhrimah Tungkop in identifying children’s Multiple Intelligences (MI) through authentic observation during an activity of printing moon shapes using banana stems. The study employed a descriptive qualitative approach with data collected through in-depth interviews and participatory observation. Data were analyzed thematically and supported by source and technique triangulation to ensure the validity of the findings. The results indicate that the teacher’s understanding of the MI concept was still focused on linguistic, logical-mathematical, and visual-spatial intelligences. Despite this limited conceptual scope, the implementation of authentic observation during the art-based activity successfully revealed a broader range of children’s intelligences. The moon-printing activity demonstrated indicators of visual-spatial intelligence through shape recognition and composition, bodily-kinesthetic intelligence through hand–eye coordination and motor control, and intrapersonal intelligence reflected in children’s ability to manage emotions, maintain focus, and show persistence during the task. Repeated observations accompanied by anecdotal records enabled the teacher to construct individual and continuous MI profiles for each child. These profiles can be utilized to design more varied, contextual, and child-centered learning strategies that align with the characteristics of early childhood learners in the Raudhatul Athfal setting. The practices observed also illustrate the connection between Gardner’s MI theory and Islamic early childhood education grounded in concrete learning activities. The findings support the development of child-friendly learning environments and encourage teacher creativity in conducting activity-based assessments. This study recommends strengthening teacher competencies through training in authentic MI assessment and further research using a research and development approach.

Interreligious dialogue in contemporary plural societies faces serious challenges, particularly due to differences in the use and interpretation of religious language, which is often understood in a monolithic and decontextualized manner. Religious language is frequently reduced to doctrinal propositions debated through logical arguments, thereby neglecting the form of life from which it emerges. This study aims to analyze the transformation of Ludwig Wittgenstein’s thought from the picture theory presented in Tractatus Logico-Philosophicus to the concept of language games developed in Philosophical Investigations, as well as its implications for understanding religious language and contemporary interreligious dialogue. This research employs a qualitative approach using a library research method through philosophical-conceptual analysis of Wittgenstein’s major works and relevant secondary literature. The findings indicate that the concept of language games allows religious language to be understood as a social practice with internal rules and contextual meanings, rather than as metaphysical propositions subject to empirical-logical verification. In the context of interreligious dialogue, this approach helps explain differences in the meanings of religious terms such as “salvation” or “God” without treating them as absolute logical contradictions. By viewing religious language as part of language games rooted in distinct forms of life, interreligious dialogue can be directed toward mutual understanding and respect for diversity rather than the pursuit of theological uniformity.
