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.

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.

Background: The prevalence of Chronic Energy Deficiency (SEZ) of pregnant women nationally is still 16.9%, and anemia reaches 27.7%, so the development of local food-based Supplementary Feeding (PMT) is needed. Brownies with the substitution of red spinach as a source of iron and purple sweet potato flour as an energy source have the potential to be developed as an alternative to PMT. This study aims to determine the acceptability and nutritional content of red spinach brownies with the addition of purple sweet potato flour as an interlude food for pregnant women. Method: Design using the Complete Random Design (RAL) method. The formulation of making brownies consists of three treatments with a comparison between (red spinach pureee and purple sweet potato flour) as follows: F1 (50:50), F2 (60:40), and F3 (40:60). The acceptance test was conducted using a hedonic test of color, aroma, taste, and texture on 30 semi-trained panelists. Analysis of nutritional content includes moisture content (thermogravimetry), ash content (dry ashing), protein (Kjeldahl), fat (Soxhlet), carbohydrates (by difference), and Fe (Atomic Absorption Spectrophotometry). The data were analyzed using the Kruskal-Wallis test. Research Results: The acceptability test showed that there was no significant difference between the formulations. The F3 formulation with a ratio of 40% red spinach pureee and 60% purple sweet potato flour obtained the highest preference value and was determined as the best formulation. The nutritional content of the F3 formulation includes protein 10.447%, fat 8.047%, carbohydrates 1.5579%, Fe 0.0005%, moisture content 20.68%, and ash content 1.4875%. Conclusion: There was no significant effect of each formulation on the acceptability of Brownis Suggestion: It is hoped that the next researcher can improve product formulation and processing processes to maintain and increase iron (Fe) levels in brownies.

This Community Service (CS) initiative was executed collaboratively by faculty members from five universities—Universitas Pamulang, Universitas Presiden, Universitas Trisakti, Universitas Pembangunan Jaya, and Universitas Borobudur—in Kasomalang Kulon Tourism Village, Subang Regency, West Java, on April 17, 2026. This initiative aimed to instruct village leaders, as prospective catalysts for change in waste management and renewable energy, on the technique for converting plastic trash into pyrolysis-derived alternative fuel and the Triboelectric Nanogenerator (TENG) energy harvesting technology. This activity addresses the critical issues of plastic waste pollution and the exhaustion of fossil fuel reserves. Annually, almost 8 million tonnes of plastic waste infiltrate the oceans, yet merely 9% of all plastic ever manufactured is effectively recycled. The collaborative effort encompassed Electrical Engineering, Computer Systems, Petroleum Engineering, Information Systems, Product Design, and Agrotechnology. The instructional techniques employed comprised lectures and conversations. The activity's results indicated that participants acquired a thorough comprehension of pyrolysis mechanisms, the principles of TENG energy conversion, and its possible applications at the village level. Despite the absence of direct implementation, the cadres shown significant motivation to facilitate technology adoption inside their communities. This PKM model demonstrates that interdisciplinary collaboration across universities is effective in providing innovative technological education to rural populations.

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.

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.

This study aimed to describe: (1) the development process of the Eksotika Pop-Up Book media on local wisdom material for fourth-grade elementary school students, (2) the validity of the media, (3) its effectiveness, and (4) students’ responses toward the media. This research employed a Research and Development (R&D) method using the ADDIE model, consisting of Analyze, Design, Development, Implementation, and Evaluation stages. The study was conducted at UPT SDN 256 Gresik. Data were collected through interviews, observations, validation questionnaires from media and material experts, student response questionnaires, and learning outcome tests. The results showed that the Eksotika Pop-Up Book media was feasible for use in learning activities, obtaining a media expert validation score of 95.31% and a material expert validation score of 93.75%, both categorized as very valid. The media and content were aligned with the learning objectives and supported students’ understanding of local wisdom traditions in Gresik, including Rebo Wekasan, Malam Selawe, Pasar Bandeng, Sanggring, Pencak Macan, and Damar Kurung. Therefore, the Eksotika Pop-Up Book is considered valid and feasible as an alternative learning medium for Grade IV IPAS learning.

Diabetes mellitus, as a persistent non-infectious metabolic pathology increasingly prominent in the global epidemiological spectrum, is fundamentally characterized by dysfunctional hyperglycemia rooted in primary disruptions of pancreatic insulin hormone synthesis or peripheral resistance to its biological action, thereby inducing dynamic imbalances in gluconeogenesis and glycolysis pathways; amid the hypothesis that body mass index (BMI) as a measure of central adiposity potentially mediates variability in serum glucose levels, this quantitative observational study with a cross-sectional design rigorously tests the causal relationship between BMI and fasting/random blood glucose concentrations in a cohort of 134 adult subjects with type 2 diabetes mellitus affiliated with primary care services at Puskesmas Bongo II, Boalemo Regency, through an inclusive total sampling recruitment strategy, precision anthropometric measurement instruments (height, weight, WHO BMI categorization), and laboratory-validated glucometric validation, with multivariate inferential processing based on the Chi-Square independence test at a Type I error rate of α=0.05 using the latest edition of the SPSS analytical suite; the demographic profile highlights female gender supremacy (90 individuals, 67.2%), the normoweight group (78 cases, 58.2%), concurrent with substantial glycemic elevation prevalence (78 subjects, 58.2%), but the crucial statistical output reveals a p-value of 0.831 (>0.05) that negates any probabilistically meaningful association, thus the substantive conclusion affirms the non-significance of the BMI-glucose relationship in this local context, while implying the dominance of alternative etiopathogenic factors such as hypercaloric macronutrient intake patterns, deficits in aerobic/anaerobic physical activity, non-adherence to multidisciplinary pharmacological protocols (e.g., metformin/oral hypoglycemics), and a comprehensive management paradigm integrating behavioral education, continuous monitoring, and personalized interventions to mitigate long-term cardiovascular risks across the diabetes mellitus spectrum.

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 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.

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.

Diabetes mellitus (DM) is a degenerative disease commonly experienced by the elderly and requires proper treatment to prevent complications. One traditional treatment alternative used to lower blood sugar levels is bay leaf decoction. This study aimed to determine the effect of bay leaf decoction on reducing blood sugar levels among the elderly in Peuniti Village, Baiturrahman District, Banda Aceh City. The study employed a quasi-experimental design with a one-group pretest-posttest approach. The sample consisted of 15 elderly participants selected from a population of 87 elderly individuals. Data collection was conducted by measuring blood sugar levels before and after administering bay leaf decoction once daily for 7 days. Blood sugar levels were checked using a blood glucose meter 20 minutes after consumption. Data were analyzed using a dependent t-test. The results showed that before treatment, all respondents (100%) were categorized as having DM, with an average blood sugar level of 211.0 mg/dL. After treatment, all respondents (100%) were categorized as non-DM, with an average blood sugar level of 160.4 mg/dL. Statistical analysis showed a significance value of 0.004 (p < 0.05), indicating that bay leaf decoction significantly reduced blood sugar levels in the elderly.

Family Medicinal Plants (TOGA) are one form of natural resource utilization that can be used as an alternative traditional medicine as well as an effort to improve public health. Medicinal plants are widely used by the community because they are easy to obtain, relatively safe, and have lower costs compared to modern medical drugs. This study aims to examine the utilization of TOGA plants as an effort to improve the health of the people of Kudu Ganting Village through a literature study approach. The method used was a literature review by examining various scientific sources such as books, journals, and research reports related to family medicinal plants. The results of the study indicate that plants such as ginger, turmeric, lemongrass, temulawak, and betel leaves provide various health benefits, including improving body immunity, treating digestive disorders, and functioning as natural antiseptics. Therefore, the utilization of TOGA plants can serve as an effort to improve community health while also making productive use of home yard land.

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.  

This community service activity aims to improve the community’s knowledge and skills in making natural-ingredient massage oils as both an alternative health product and a business opportunity.

In addition, participants were also provided with training in packaging, business management, and basic marketing. The results of the activities showed an increase in the community’s knowledge and skills in processing natural ingredients into massage oil products that are safe, effective, and economically valuable. This program is expected to promote community selfreliance and increase family income through the development of businesses based on local potential.

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 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.
