This study was conducted based on the low level of student activeness and understanding in IPAS learning at the elementary school level. The objective of this research was to determine the effectiveness of the role play method in improving students’ activeness and learning outcomes. This study employed a classroom action research approach involving 27 students. The data were collected through observation and evaluation of student learning outcomes. The findings revealed a significant improvement in both student participation and understanding after the implementation of the role play method. Students became more active in asking questions, responding to the teacher, and participating in classroom activities. In terms of learning outcomes, 85.2% of students were able to answer questions correctly and demonstrated good understanding, while the remaining 14.8% also achieved the minimum criteria. These results indicate that learning through direct experience enhances students’ comprehension. The implication of this study suggests that the role play method can be used as an effective alternative teaching strategy to create an interactive, engaging, and student-centered learning environment in elementary education.

Inclusive education aims to provide equal learning opportunities for all students, including those with special needs, within regular educational settings. However, mathematics learning in inclusive classrooms remains challenging because mathematical concepts are often abstract and require logical reasoning that may not be easily accessible to learners with diverse cognitive characteristics. Ethnomathematics has emerged as an alternative approach by integrating cultural practices, local wisdom, and students’ daily experiences into mathematics instruction, creating more meaningful and accessible learning environments. This study aims to analyze the development, implementation patterns, opportunities, and research gaps related to ethnomathematics in inclusive mathematics learning. A literature review method was employed by examining scientific publications from 2020–2025 obtained from Google Scholar, Scopus, ERIC, Springer, and ProQuest databases. Data were analyzed through content analysis involving reduction, classification, interpretation, and synthesis. The findings indicate that ethnomathematics has been implemented through cultural artifacts, digital teaching materials, and project-based contextual learning. The approach supports inclusive learning through multi-representational access, instructional adaptations, scaffolding strategies, and collaborative teaching practices aligned with Universal Design for Learning principles. Furthermore, ethnomathematics enhances students’ motivation, conceptual understanding, mathematical literacy, and cultural identity. Nevertheless, studies focusing on disability-specific adaptations and long-term learning outcomes remain limited and require further investigation.

Based on the 2023 Indonesian Health Survey, the prevalence of overweight among adults reached 23.4% nationally and 24.5% in East Java Province. This condition highlights the need for food innovation, particularly high-fiber snacks suitable for overweight adults. This study aimed to develop cereal based on okara (soy pulp) flour and mung bean flour as an alternative high-fiber food product. Organoleptic testing was conducted on 30 semi-trained panelists evaluating color, aroma, texture, and taste using hedonic and hedonic quality tests. Data were analyzed using the Kruskal–Wallis test followed by the Mann–Whitney test, while nutrient content analysis was analyzed using One Way ANOVA followed by Duncan’s post hoc test. The results showed that in the hedonic test, color, texture, and taste parameters were significantly different (p<0.05), while aroma was not significantly different (p>0.05). In the hedonic quality test, color and taste showed significant differences (p<0.05), whereas aroma and texture did not (p>0.05). Overall, formulation 922 was the most preferred by panelists. The nutritional content of the cereal ranged from 407–410 kcal for energy, 76.44–77.53% carbohydrates, 8.91–9.66% protein, 6.80–7.30% fat, 5.20–5.51% moisture, 1.26–1.41% ash, and 9.72–10.90% total dietary fiber. The developed cereal is classified as a high-fiber food and has potential as a healthy snack for overweight adults.

The increasing complexity of urban transportation systems demands intelligent and measurable navigation methods. Medan City, the capital of North Sumatra Province, has a dense road network with multiple route options that often confuse road users. Dijkstra's Algorithm, developed by Edsger Wybe Dijkstra in 1959, is a greedy-based computational approach proven effective for solving the shortest path problem on non-negative weighted graphs. This study applies Dijkstra's Algorithm to determine the shortest route from Medan Railway Station to Universitas Negeri Medan (UNIMED). The road network was modeled as an undirected weighted graph with 15 nodes and 16 edges, where edge weights represent actual road distances measured via Google Maps. The graph has a density of 0.152, confirming its sparse graph characteristic. Three alternative routes were identified and analyzed. The algorithm was implemented in Python 3 using the heapq module as a priority queue. Results show that the optimal route is A → B → C → E → F → M → N → O via Jl. M.T. Haryono, Jl. Aipda KS Tubun, Jl. Madong Lubis, and Jl. Prof. H.M. Yamin, with a total distance of 6.64 km. This achieves 99.1% accuracy compared to Google Maps, with a deviation of only 0.06 km. The optimal route is 6.25% more efficient than Alternative Route 1 (7.30 km) and 11.9% more efficient than Alternative Route 2 (7.54 km). The algorithm executes in under 1 millisecond with time complexity O((V+E) log V). These findings confirm Dijkstra's Algorithm as highly effective for medium-scale urban road network optimization.

Dijkstra's algorithm is one of the algorithms in graph theory that is used to solve the problem of the shortest path of a graph at each vertex that has a non-negative value. This algorithm was discovered by Edsger Wybe Dijkstra, a scientist from the Netherlands. The search for the shortest route for product delivery can be calculated through the application of the Dijkstra algorithm in the problem being faced. The problem of decision making for selecting the shortest route is still manual, so it experiences several obstacles, including the absence of a systematic and computerized system to assist the decision-making process in determining the route for shipping goods, the determination of shipping routes still depends on manual estimates so that the time taken between deliveries becomes inconsistent, the operational costs of shipping are relatively high because there is no optimal route determination system. Facing these problems, a system is needed that can minimize delays and increase effectiveness in shipping goods, namely determining the shortest route using the Dijkstra algorithm. This system works by finding various alternative routes for shipping goods at PT AMSA to address various structured and unstructured problems using data and models. To process this data and models, a method called the Dijkstra algorithm is required. Based on the description above, researchers will create a method for determining the shortest route for shipping goods at PT AMSA using the Dijkstra algorithm to facilitate the company's process of determining the shortest route.

Health issues among the elderly are often related to declining bodily functions, digestive disorders, and specific nutritional needs for easily digestible foods. The 60-and-older age group is at high risk for gastrointestinal disorders due to low fiber intake. Therefore, alternative foods are needed that are soft in texture, neutral in taste, safe, and nutritious. One potential solution is the development of food products based on tempeh gembus with the addition of banana hearts, which are rich in fiber, soft in texture, and readily available. This study employed an experimental method using a Completely Randomized Design (CRD) to test three formulation variations (F1, F2, F3). The nutritional content of formulation F1 includes energy 111.575 kcal, carbohydrates 20.185 g, protein 6.91 g, fat 0.355 g, and fiber 6.67 g. Formula F2 contains 88.225 kcal of energy, 14.095 g of carbohydrates, 7.72 g of protein, 0.205 g of fat, 7.3 g of fiber, and 0.0015% flavonoids. Formula F3 has 107.015 kcal of energy, 7.995 g of protein, 0.295 g of fat, 6.88 g of fiber, and 0.0021% flavonoids. In conclusion, the best tempeh with added banana hearts is Formula F2, with its nutritional content, fiber, flavonoids, and BAL >10⁸ CFU/g, which has the potential to serve as a functional food and probiotic source to help improve digestive health in the elderly. Further testing is recommended directly on elderly groups, along with product shelf-life testing.

  Red dragon fruit contains bioactive compounds such as vitamin C, flavonoids, and polyphenols that have antioxidant potential and possess natural pigments that can be used as cosmetic colorants. This study aims to formulate and evaluate a blush-on powder preparation from dragon fruit pulp extract as an alternative natural colorant. The evaluation includes organoleptic testing, homogeneity, pH, irritation, spreadability, fineness, moisture content, and antioxidant activity. The results showed that the formulation met most of the requirements, exhibiting a pink color, a smooth texture, no odor, homogeneity, a pH of 6 suitable for the skin, no irritation, even spreadability within 4 applications, a fineness degree of 97.6%, and a moisture content of 6.91%. Antioxidant activity showed an IC₅₀ value of 0.3036 ppm (very strong), although the relative inhibition percentage was low (18.35%). Thus, dragon fruit extract has the potential as a natural ingredient in blush-on powder that provides both color and antioxidant benefits.

Scientific articles not only function as a medium for conveying information but also as a representation of the author’s academic credibility and intellectual authority within the scientific community. In academic writing, language plays a crucial role in shaping the author’s identity, reliability, and scholarly position. This research aims to conceptually examine the relationship between linguistic choices and the construction of authority in Indonesian-language scientific articles. The study employs a library research method with a critical discourse analysis approach toward various references related to functional linguistics, discourse studies, and ethics in academic writing. The findings indicate that academic authority is constructed through several linguistic aspects, including lexical precision, grammatical objectivity, cohesion and coherence of ideas, as well as a careful epistemological attitude that remains open to alternative interpretations and scientific dialogue. In addition, the use of formal, systematic, and evidence-based language contributes significantly to strengthening the legitimacy of scientific arguments. Within this framework, language is not merely a communication tool used to present ideas, but also an instrument for legitimizing knowledge and reinforcing the author’s credibility, reliability, and authority in academic discourse. Therefore, mastery of academic language becomes an essential component in producing quality scientific articles.

The crisis of human spirituality, which separates the inner dimension from the universe, is at the root of the current global environmental crisis. The purpose of this study is to comprehensively examine how Sufi principles are applied in environmental conservation practices at the Shadana Islamic Boarding School in Padarincang, and to determine how the teachings of the book Fathul 'Arifin influence the formation of the students’ ecological ethics. This research was conducted qualitatively through a case study. Data were collected through document analysis, in-depth interviews, and participatory observation from September 22 to October 5, 2025. The results indicate that the concept of spiritual purification, or tazkiyatun nafs, is integrated with nature conservation by activating the seven lathaif. Environmental conservation, such as protecting springs and forests, is viewed as a form of spiritual devotion to the Creator, as human awareness of the elements of fire, water, wind, and earth fosters a strong inner connection with the macrocosm or the universe. The results indicate that the santri paradigm has shifted from anthropocentrism to theocentrism. This study proposes an “Eco-Sufism” model, grounded in the transformation of inner consciousness, as an alternative solution to address environmental degradation. This approach emphasizes that to foster sustainable harmony among humans, God, and the universe, ecosystem sustainability requires a strong foundation of spirituality.

The use of synthetic pesticides in the agricultural sector remains the primary choice for farmers in Indonesia due to their high effectiveness, but their massive use has negative impacts on human health and the environment. Therefore, there is a need for environmentally friendly and sustainable pesticide innovations. Red onion peel waste with the addition of TiO₂ nanotechnology is a strategic development step as a solution to the dangers of synthetic pesticides. Red onion peel contains bioactive compounds such as acetogenin, squamocin, gibberellin, cytokinin, and abscisic acid, which have the potential to be natural pest control agents. The process of making organic pesticides is carried out through the maceration of onion skins, followed by the addition of TiO₂ nanoparticles that act as photocatalytic catalysts to increase pesticide effectiveness and degrade synthetic pesticide residues. The development of these organic pesticides is in line with the principles of Green Chemistry, particularly designing safer chemicals, catalysis, design for degradation, and real-time pollution prevention. Through the implementation of strategic steps such as research, testing, socialization, and continuous evaluation, TiO₂ nanotechnology-based organic red onion peel pesticides have the potential to become a safe, effective, and environmentally friendly alternative in supporting sustainable agriculture in Indonesia.

Knowledge should not only make human beings intellectually capable, but also guide them to understand the meaning and direction of life. However, in modern education, knowledge is often reduced to an instrument for obtaining grades, degrees, employment, and material success. This condition indicates a crisis of meaning in education, where knowledge grows rapidly but is not always followed by moral awareness and spiritual maturity. This article examines the Philosophy of Unity of Sciences as an alternative paradigm to restore the meaning of knowledge in modern education. This study uses library research with a descriptive-critical approach. The primary sources include the Qur’an, Hadith, Al-Ghazali’s Iḥyā’ ‘Ulūm Al-Dīn, Syed Muhammad Naquib Al-Attas’ Islam and Secularism, and the Javanese ethical text Serat Wedhatama. This article is also strengthened by the thoughts of Muslim scholars such as Al-Kindi, Al-Farabi, Ibn Sina, Al-Biruni, Ibn Al-Haytham, Al-Khawarizmi, and Ibn Khaldun. The result of this study shows that the Philosophy of Unity of Sciences views all knowledge as originating from Allah. Therefore, religious knowledge and general knowledge should not be separated or opposed to each other. Both should work together to form human beings who are faithful, rational, ethical, and responsible. In this sense, knowledge can be understood as “a way home”, namely a way to return to God, to the self, to humanity, and to nature.

This study aims to analyze the effect of combining bait types and immersion durations on the catch yields of blue swimming crabs (Portunus pelagicus) in the waters of Kuala Penet, East Lampung. The research method employed was a field experiment utilizing a factorial Completely Randomized Design (CRD). The focus of the study was directed toward two types of bait, namely goldstripe sardine (Sardinella spp.) and chicken intestines, with three variations of immersion duration: 6 hours, 12 hours, 18 hours, and 24 hours. Through statistical analysis, it was discovered that the combination of goldstripe sardine bait and a 6-hour immersion duration provided the most optimal catch yields. Nevertheless, chicken intestines demonstrated strong potential as an economical and sustainable alternative bait at a 12-hour immersion duration. The interaction between the bait type and immersion duration variables proved to be significant, thereby supporting an integrated approach to the management of collapsible pots. These findings provide a scientific basis for formulating sustainable crab fishing guidelines that can be adopted by local fishermen and relevant authorities to support the ecosystem-based conservation of coastal fishery resources in East Lampung.

This study aims to examine the application of a modified direct learning strategy combined with the demonstration method to improve students' cognitive abilities. The direct learning strategy is an approach that emphasizes the systematic and gradual delivery of material, so that students can understand concepts in a more structured manner. However, in practice, this strategy needs to be modified to be more engaging and appropriate to the characteristics of students. The demonstration method is used as a form of reinforcement in the learning process, where students not only receive information verbally but also directly observe the processes, events, or concepts being studied. This allows students to gain a more concrete and meaningful learning experience. Modifications to the learning strategy are carried out through adjustments to models, methods, media, and learning facilities and infrastructure to optimally support the achievement of learning objectives. Students' cognitive abilities are the main focus of this study, which include aspects of knowledge, understanding, application, analysis, evaluation, and creation according to Bloom's taxonomy. With the implementation of appropriate learning strategies, students are expected to be able to develop more active and critical thinking skills. The results of the study indicate that a modified direct learning strategy with the demonstration method has the potential to significantly improve students' cognitive abilities. Therefore, this approach can be used as an alternative, effective learning strategy to create a more interactive, engaging, and meaningful learning process.

The crisis of authority in global culture is a complex phenomenon reflecting a fundamental shift in how humans understand truth, values, and the sources of legitimacy of knowledge. This research focuses on the dynamics of epistemological change in global society influenced by digital technology, cultural relativism, and value pluralism. The main issue studied is how this crisis of authority influences the construction of truth and value systems in contemporary society, as well as its implications for social and spiritual life. The aim of this research is to develop an interdisciplinary analysis that integrates perspectives from philosophy, sociology, theology, and media studies in understanding this phenomenon. The method used is a qualitative approach based on systematic literature studies with a critical analysis of recent academic sources. The main findings indicate that the crisis of authority is characterized not only by the weakening of traditional institutions but also by the emergence of "alternative authorities" based on algorithms, public opinion, and subjective experience. This results in the fragmentation of truth, the relativization of values, and a crisis of epistemological legitimacy. The synthesis of this research confirms that the reconstruction of authority requires an integrative approach that combines rationality, ethics, and spiritual dimensions. In conclusion, the crisis of authority in global culture is not merely a challenge, but rather an opportunity to build a new epistemological paradigm that is more holistic, reflective, and rooted in transcendent values.  

The implementation of smoking prohibition policies in Islamic boarding schools continues to depend largely on manual monitoring methods, which often face challenges related to consistency and supervision range. This study aims to design an Internet of Things (IoT)-based cigarette smoke detection system as an alternative monitoring approach that is more effective, measurable, and sustainable. The system design combines an MQ-2 gas sensor with a NodeMCU ESP8266 microcontroller programmed through the Arduino IDE platform. When smoke levels detected by the sensor exceed the predetermined limit, the system automatically triggers a buzzer and LED as warning indicators while simultaneously sending monitoring data to cloud-based platforms such as Firebase or ThingSpeak for real-time observation through web interfaces. The research outputs include a comprehensive system design consisting of system architecture, electronic circuit schematics, flowcharts, and pseudocode that are systematically arranged to support future prototype development and implementation. Through this design, the proposed system is expected to provide an initial technological solution that can enhance the effectiveness of monitoring and enforcing smoke-free regulations within Islamic boarding school environments.

This study aims to know the decision-making strategies in individuals with pragmatic personality. The approach used was qualitative with a case study method. The subjects of the study consisted of three individuals who were selected using purposive sampling techniques based on pragmatic personality characteristics, i.e. oriented to results, efficiency, and practical considerations in decision making. Data were collected through semi-structured interviews and observations, then analyzed using thematic analysis. The results of the study showed that all three respondents had relatively similar decision-making patterns, namely starting with understanding the problem, followed by identification and evaluation of multiple alternatives, as well as considering the advantages and disadvantages of each option. In determining the final decision, pragmatic individuals tend to choose solutions that are realistic, simple, effective, and have the lowest risk yet provide the optimal benefit. Additionally, in the face of important decisions, respondents showed a cautious attitude by calming themselves, not rushing, as well as partially considering the opinions of others as additional evaluation material. Overall, the findings of this study suggest that pragmatic personality plays a role in forming logical, adaptive, and real outcome-oriented decision-making strategies in daily life.

 This research addresses the growing tendency of contemporary education to prioritize cognitive achievement while marginalizing character formation and spiritual development, resulting in an imbalanced educational paradigm that affects the holistic growth of learners in various educational contexts. In response, the research critically examines the concept and principles of Christian education as articulated by Ignatius Loyola, particularly in relation to contemporary educational challenges and the need for meaningful transformation in learning processes today. The study employs a qualitative approach using a literature review method, drawing on relevant academic sources such as books, peer-reviewed journal articles, and theological writings to support systematic and critical analysis. The findings indicate that Ignatian educational thought emphasizes holistic human formation through the integration of intellectual, moral, and spiritual dimensions, grounded in the principles of Ad Majorem Dei Gloriam, Cura Personalis, and Find God in All Things, which together foster reflective, value-oriented learning. The study contributes to contemporary educational discourse by offering an alternative framework that promotes holistic development, strengthens character formation, and addresses the limitations of cognitively oriented educational models in diverse educational practices.

This study aims to analyze the understanding of Micro, Small, and Medium Enterprises (MSMEs) in Harjosari II Village regarding Islamic financial inclusion and its contribution to expanding access to business capital financing. Although the national financial inclusion index continues to increase, the implementation of Islamic financial inclusion still faces challenges at the grassroots level. This research used a descriptive qualitative method with data collection techniques consisting of observation, documentation, and in-depth interviews with MSME owners in Harjosari II Village and staff from KSPPS & BMT Syariah Sejahtera (SS) Medan. The findings show that MSME owners’ understanding of Islamic financial inclusion is influenced by religiosity and the perception of justice through the profit-sharing system. Islamic financial inclusion is implemented through a kinship approach and simplified administrative procedures for the informal sector. However, the main obstacles to expanding financing access include limited Islamic financial literacy, restricted financing ceilings, and entrepreneurs’ lack of confidence in formal banking procedures. Islamic financing contributes to increasing production capacity and providing spiritual peace of mind by offering capital alternatives free from usury (riba). This study recommends strengthening direct technical socialization and implementing more flexible financing ceiling policies to support MSME growth in suburban areas.

Social change in the context of liquid modernity has significantly influenced how people understand interpersonal relationships, love, and commitment. Contemporary relationships tend to be flexible, temporary, and oriented towards the fulfillment of subjective needs, making loyalty and long-term commitment often viewed as a threat to personal autonomy. Based on Zygmunt Bauman's analysis of liquid modernity and liquid love, this study examines the crisis of modern relationships as an anthropological and theological crisis of meaning. Specifically, the study focuses on the Nota Doktrinal Una Caro as the Catholic Church's theological response to these relational dynamics. Using a library research method with a qualitative and analytical-hermeneutical approach, this study interprets magisterial texts in critical dialogue with the sociological theory of liquid modernity. The research findings show that the Nota Doktrinal Una Caro offers an integrated anthropological-theological vision by affirming Catholic marriage as a permanent, monogamous, and indissoluble communion of life and love. Fidelity is understood as the highest actualization of freedom, while sexuality is seen as an expression of total self-giving, offering an alternative to the fragmentation of modern relationships. The study also emphasizes the importance of a dialogical and formative approach in family counseling.

The establishment of national territorial boundaries is a strategic priority to safeguard sovereignty, maintain security stability, and strengthen bilateral relations between Indonesia and Malaysia as well as Timor-Leste. As of 2024, there remain nine Outstanding Boundary Problems (OBP) with Malaysia and two unresolved segments with Timor-Leste. These issues stem from the continued relevance of outdated colonial agreements, limited diplomatic capacity, weak inter-agency coordination, and minimal support from modern surveying technology. Based on an analysis of four policy alternatives using the criteria of effectiveness, efficiency, and long-term impact, the Strengthening of Intensive Bilateral Diplomacy has been identified as the priority policy. Implementation is directed to the Badan Nasional Pengelola Perbatasan (BNPP) as the main coordinator, supported by regulatory frameworks, diplomatic resources, and cross-ministerial/institutional coordination. Through this strategy, the resolution of pending boundary segments can be accelerated, legal certainty over national territory can be strengthened, security stability in border areas can be improved, and bilateral relations can become closer. Furthermore, Indonesia needs to strengthen diplomatic strategies, leverage technology, and enhance inter-agency coordination to accelerate the resolution of national border disputes. This policy directly contributes to achieving territorial sovereignty and sustainable development toward Indonesia Vision 2045.
