This article examines the concept of propositions in mathematics, which are statements referred to as (closed sentences, false, values, and true values). The discussion covers negation, or what is known as negation, as operations that have truth values and truth tables. In addition, this article examines conjunction, or compound propositions that are true. (the combination of two questions), which involves two propositions with either true or false values. Furthermore, this article also examines disjunction, which involves statements containing conjunctionand also has truth tables. The primary objective is to provide a concise yet comprehensive understanding of propositions as logical and mathematical concepts. In addition, this article examines conjunction, or compound propositions that are true. A conjunction involves two propositions that are combined using the logical operator "and," symbolized by ∧. The conjunction of two propositions is true only when both individual propositions are true. For example, if P is true and Q is true, then the conjunction P ∧ Q is also true. However, if either P or Q is false, the conjunction P ∧ Q becomes false. The truth table for conjunction helps to clarify these conditions. Conjunction is often used in mathematical proofs, where multiple conditions must be satisfied simultaneously for a statement to hold true. Furthermore, this article also examines disjunction, which involves statements containing conjunction and also has truth tables. Disjunction, represented by the symbol ∨, involves two propositions and is true if at least one of the propositions is true. If both propositions are false, the disjunction is false. For instance, if P is false and Q is true, then P ∨ Q is true. The truth table for disjunction provides clarity on how this operation works. Disjunction is frequently used in mathematics and logic to express situations where at least one condition must be satisfied.

The lack of interest of young children in learning numbers is a common challenge in kindergarten learning activities. Children tend to be passive during the mathematics learning process because the approach used is not appropriate to their age developmental characteristics, which prefer play, movement, and direct interaction with concrete media. To address this problem, the Community Service Program (KKN) at At-Tien Kindergarten, Sumber Gayam, focused on learning innovation by designing a simple media called the Mathematics Ferris Wheel. This media was designed by combining elements of play and motor activity, making it more engaging for children. The research in this community service activity used a Participatory Action Research (PAR) approach, which actively involved teachers and students in the planning, implementation, and evaluation stages. The media was implemented by children turning the Ferris wheel in turns, then calling out the number indicated along with the numbers before and after. Through this activity, children not only learned to recognize number sequences but also practiced concentration, courage, and communication skills. The implementation results showed that the use of the Mathematics Ferris Wheel was able to significantly improve the understanding of number concepts in early childhood. Furthermore, children's active involvement in learning also increased, demonstrated by their enthusiasm in participating in the game from start to finish. Teachers found this media to be highly beneficial because it is easy to use, flexible, and adaptable to teach other topics such as colors, shapes, and letters. Thus, this KKN activity demonstrates that innovative, participatory learning media can create a fun, contextual, and effective learning environment. Such efforts are a practical solution to improving the quality of learning in early childhood education

This systematic literature review examines the philosophy of science approaches to user security in distributed devices, such as IoT and Federated Learning. The review was conducted in response to the exponential growth of connected devices and the increasing security threats, including cyberattacks, data breaches, and unauthorized access. As distributed systems become more complex, traditional security approaches, such as cryptography and differential privacy, are often insufficient to address the ethical, philosophical, and contextual challenges that arise in these ecosystems. Distributed devices, especially in IoT and Federated Learning contexts, rely on vast amounts of personal data. This data, often stored or processed in decentralized environments, creates significant risks to user privacy and system integrity. As the number of connected devices grows, security risks multiply, creating challenges in maintaining user trust, privacy, and overall system resilience. Conventional techniques, such as encryption, only focus on technical aspects, often neglecting the deeper philosophical dimensions, such as the nature of knowledge, privacy, and fairness in these systems. These gaps highlight the need for a more nuanced approach that incorporates philosophical perspectives into security frameworks. This study uses a systematic literature review method based on the PICOC (Population, Intervention, Comparison, Outcome, Context) framework to analyze the relevance of epistemology, ontology, and ethics in strengthening system security. By examining the foundational principles of how knowledge is constructed (epistemology), what entities exist in the system (ontology), and the ethical considerations around data and user privacy (ethics), the review provides a comprehensive understanding of how philosophical concepts can be integrated into the design and implementation of security systems in distributed environments. The results reveal that epistemological principles, such as the verification and validation of data sources and models, can significantly improve the reliability and trustworthiness of distributed systems.

Another important aspect addressed was corruption, where students were guided to recognize the value of honesty and integrity through relatable examples in daily life. The results of the activity revealed that students were able to clearly understand the dangers of drugs, recognize the different forms of bullying, and provide examples of honest and moral behavior. This indicates that early character education delivered through interactive and participatory methods can effectively enhance children’s comprehension of healthy and moral values. It is expected that similar programs can be carried out sustainably in elementary school settings as part of continuous character-building efforts to support the development of a responsible and ethical young generation

The presence of scattered waste in the environment has a significant impact on both environmental sustainability and human health. In Indonesia, the accumulation of waste has reached alarming levels, amounting to approximately 175,000 tons per day, or the equivalent of 64 million tons annually. Household activities are one of the main contributors, producing a wide variety of waste, including organic and non-organic materials. Poto Village is among the areas receiving particular attention regarding this issue due to the challenges it faces in waste management. Improper management of waste not only leads to air, water, and soil pollution but also increases the risk of various health problems within the community. One of the programs designed to address this problem is the 3R program, which emphasizes three main principles: reduce, recycle, and reuse. The purpose of this community service initiative is to improve public knowledge and awareness of effective waste management through the application of 3R practices. The activities were carried out in three main stages, namely preparation, education, and discussion through a question-and-answer session. The process began with a socialization activity that introduced the objectives, purposes, and sustainability aspects of waste management efforts in the village. The educational session was attended by 30 participants, consisting of housewives, farmers, and entrepreneurs, who represented key groups within the community. Furthermore, interviews with local cadres revealed that waste is collected weekly by garbage trucks, indicating the village’s commitment to environmental management. Participants responded enthusiastically throughout the educational sessions, showing a strong interest and positive reception toward the information provided. As a follow-up step, future activities could include hands-on training in waste management using available media and tools, which would allow participants to apply the concepts learned in a practical and sustainable manner.

This study focuses on the symbolic meanings embedded in the use of figurative language in the poetry anthology Selamat Menunaikan Ibadah Puisi by Joko Pinurbo. The research utilizes a descriptive qualitative approach, with semiotic analysis serving as the theoretical foundation. The purpose of this study is to examine how the figurative language used in the poems contributes to conveying deeper symbolic meanings, beyond their role as mere rhetorical devices. The findings of this research reveal that the figurative language within the poems plays a significant symbolic role in expressing complex themes such as inner suffering, memories, identity, alienation, and the quest for the meaning of life. Symbols like 'storm,' 'refrigerator,' 'dusk,' 'window,' 'door,' 'river,' and others are employed to represent abstract concepts, providing a more nuanced understanding of the human experience. The study identifies various types of figurative language, including metaphor, simile, personification, hyperbole, synecdoche, paradox, and irony. Each of these elements serves to enrich the meaning of the poems, adding layers of depth to the interpretation and enhancing the aesthetic experience for the reader. Through these figurative expressions, the poet effectively invites the reader to engage with both the emotional and intellectual dimensions of the poetry. This research emphasizes how Joko Pinurbo's use of figurative language transcends its traditional ornamental function, making it a powerful tool for conveying complex symbolic and existential themes. By analyzing the symbolic meanings in the poems, this study contributes to a deeper appreciation of the interplay between language, meaning, and emotion in contemporary Indonesian poetry.

Small and medium-sized enterprises (SMEs) have long been recognized as a vital driver of economic growth, particularly in rural areas where access to large-scale industries is limited. In Dahu Village, the community relies on local products such as melinjo as one of the main sources of livelihood. However, despite the potential of melinjo-based products, business development has been constrained by limited innovation, low product diversification, and weak marketing strategies. These challenges hinder the competitiveness of local SMEs in wider markets, especially in appealing to younger consumers who often prefer modern and innovative products. To address these challenges, the 2025 Student Work Study Program (KKM) conducted by the University of Bina Bangsa implemented a community empowerment project aimed at enhancing the capacity of SMEs in the melinjo sector. The program introduced the development of an innovative product, namely chocolate-flavored keceprek, a melinjo-based snack with a unique taste and higher market value. The initiative not only focused on product innovation but also provided comprehensive support in production techniques, hygienic and attractive packaging, logo and banner design, as well as digital marketing strategies tailored to rural entrepreneurs. The results of the activity highlight that even a relatively simple innovation can significantly increase product appeal, improve branding, and create new market opportunities. Early feedback indicated that chocolate-flavored keceprek products successfully attracted interest from younger consumers, demonstrating the importance of innovation in maintaining the relevance of traditional products. Furthermore, the project functioned as a collaborative platform where students and local communities worked together in applying entrepreneurial concepts to local potential. This synergy not only contributed to improving the competitiveness of SMEs in Dahu Village but also encouraged sustainable economic development in rural areas through innovation, creativity, and digital-based marketing.

This study aims to describe the application of the Jigsaw Learning method in Islamic Religious Education (PAI) learning at SMP 3 Sendana and to identify the advantages and obstacles encountered during the learning process. The research method used is descriptive qualitative, with data collection techniques through observation, interviews, and documentation. The results of the study indicate that the application of the Jigsaw Learning method can increase student activeness, strengthen group cooperation, and help understand the material more deeply and comprehensively. In this activity, students not only act as recipients of information from the teacher, but also as conveyors of material to their group mates. The process of sharing information between members encourages students to be more active in seeking out, understanding, and explaining the concepts being studied. In addition, this method also creates a collaborative and enjoyable learning atmosphere, due to the positive social interactions between students. This can increase a sense of responsibility and concern for the success of the group. However, in its implementation, several obstacles were found that require attention. Some of these include limited study time within the available lesson hours, inequality in contributions between group members which sometimes results in an uneven workload, and a lack of student readiness to understand the material independently before the group discussion process takes place. Despite the challenges, these obstacles can be minimized through effective classroom management, such as balanced group division, motivation, and intensive teacher support throughout the learning process. With the right strategy, Jigsaw Learning remains an effective and relevant method for Islamic Religious Education (PAI) learning, as it encourages the achievement of learning objectives in a participatory, active, and enjoyable manner. Therefore, this method is a worthy alternative to cooperative learning that can improve the quality of religious education at the junior high school level.

International trade involves cross-border buying and selling activities between countries, which in practice requires various transportation documents to ensure legal certainty and smooth operations. One of the main documents used is the Bill of Lading (Konosemen), which is a dated letter issued by the carrier as proof of receipt of goods to be transported to a certain destination and delivered to a specified recipient. The Bill of Lading has three essential functions: as a receipt of goods, as evidence of ownership, and as proof of a transportation contract. However, in practice, there are still frequent problems that hinder the optimal function of the Bill of Lading. One notable case is APL Co. Pte. Ltd. v. CV. Dua Sekawan Sejati, which involved discrepancies between the goods shipped and those stated in the Bill of Lading. This study adopts a normative juridical method by examining applicable legal provisions and theoretical concepts related to the law of contracts and transportation. The findings show that discrepancies between the goods shipped and those listed in the Bill of Lading constitute a breach of promise or default under Article 1320 of the Indonesian Civil Code. The Bill of Lading, in this case, serves as a legally binding transportation contract that obligates both parties to fulfill their respective responsibilities. Failure by one party to comply with the terms of the contract results in legal consequences in the form of claims for compensation by the aggrieved party. This research emphasizes the importance of accuracy and accountability in the issuance and use of Bills of Lading in international trade to avoid disputes and ensure legal certainty. Strengthening the regulation and enforcement of Bill of Lading functions is crucial for protecting the rights of parties engaged in cross-border trade.
