The evaluation results showed a significant increase in students' understanding of bullying, with an average level of understanding reaching 80.83%. Students were able not only to identify the types of bullying but also to understand the long-term impacts on both victims and perpetrators. This outreach program also helped students understand the legal regulations governing bullying and encouraged them to report or stop such acts. This program emphasizes the importance of a planned and sustainable approach involving teachers and parents to prevent bullying, as well as creating a safe learning environment and supporting child protection.

Toddler age is often called the golden period because during this period brain nerve development occurs, especially myelination, as well as a critical period. The golden period can be achieved if toddlers' nutritional needs are optimally met. On the other hand, if babies and toddlers do not get the food they need, the golden period will change into a critical period, thus disrupting their growth and development. The level of education of parents will affect the health and well-being of children, because this is inseparable from the nutritional status of children. Mothers with a high level of education will have a clearer opportunity to absorb information compared to mothers with less or no education. With a good level of education, it is hoped that a mother will be willing and able to behave well in order to improve her child's nutritional status. This Community Service activity aims to provide health education on balanced nutrition to reduce stunting in the community, especially mothers with toddlers in Desa Cangguk, Kecamatan Tanah Pasir, Kabupaten Aceh Utara. This activity used a participatory approach involving lecturers, students, health workers, and the community. The results showed an increase in public understanding and awareness of stunting prevention. It is hoped that this activity will raise public awareness about balanced nutrition for children

This study aims to analyze the role of UINSU’s Community Service Program (KKN) students in enhancing Islamic entrepreneurial awareness among the residents of Pahang Village, Talawi District, Batu Bara Regency. The KKN program serves as a platform for applying academic knowledge while empowering communities through educational, persuasive, and participatory approaches. The students introduced fundamental concepts of Islamic entrepreneurship, including principles of justice, honesty, sustainability, and the avoidance of riba, gharar, and maisir. Through a series of activities such as seminars, micro-business training sessions, financial management mentoring based on sharia principles, and simple business model simulations, the villagers began to show improved understanding of Islamic economic values. Moreover, the active involvement of students created an inclusive learning environment that was accessible to various community groups. The findings indicate that the presence of KKN students contributed positively to cultivating entrepreneurial motivation, particularly among youth and micro-business actors. This improvement was reflected in changes in mindset, interest in initiating halal businesses, and increased awareness of applying sharia principles in daily economic activities. Thus, the KKN program not only provides practical experience for students but also offers a tangible contribution to strengthening sharia-based economic empowerment at the village level.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.

Chronic kidney disease (CKD) is a growing global health concern that frequently remains undiagnosed until advanced stages. Early detection through simple laboratory screening is essential to prevent disease progression and associated cardiometabolic complications. This community service program aimed to assess kidney function using serum creatinine and estimated glomerular filtration rate (eGFR), while increasing public awareness regarding CKD prevention. A total of 59 participants were included, with a mean age of 39.15 ± 15.39 years (range 16–75 years), predominantly female (74.58%). The mean serum creatinine level was 1.0 ± 0.19 mg/dL, and the mean eGFR was 91.08 ± 20.53 mL/min/1.73 m². Most participants demonstrated normal kidney function (28.8%) or mild decline (21.6%). A progressive reduction in eGFR with increasing age was observed, reflecting the physiological decline in nephron mass and renal perfusion. The program also provided education on kidney-protective practices, including optimal blood pressure control, diabetes management, adequate hydration, and avoidance of nephrotoxic agents. This intervention improved participants’ understanding of CKD risk factors and the importance of regular screening. In conclusion, serum creatinine and eGFR evaluation offer simple, accurate, and practical tools for early CKD detection, supporting promotive–preventive strategies to slow disease progression and enhance quality of life in at-risk populations.

This study aims to analyze the factors that influence students' interest in continuing their education to college using a machine learning approach. Data was collected through an online questionnaire completed by 727 students between July 27 and August 22, 2025, covering 23 variables consisting of respondent identity (gender, grade level, major) as well as internal and external factors such as parental support, learning motivation, and preferred type of college. The data preparation stage was carried out through column cleaning, deletion of empty data, encoding of categorical variables, and division of the dataset into 80% training data and 20% test data. The Naive Bayes algorithm of the CategoricalNB type was used because it was suitable for the categorical nature of the data. The evaluation results showed that the model was able to predict student interest with 96% accuracy. For the class of students interested in continuing their studies, the precision, recall, and F1-score values were above 0.95, while the performance in the class of students who were not interested was slightly lower due to the smaller amount of data. These findings show that Naive Bayes is proven to be effective and reliable in classifying students' interest in continuing their studies and can be the basis for decision-making in designing more targeted educational strategies.

This research examines the application of the Elliptic Curve Digital Signature Algorithm (ECDSA) in a blockchain system as a security solution for digital payment systems in Indonesia. Using a descriptive-qualitative approach based on literature review and conceptual simulations using Python, this study discusses the working principles of ECDSA, its advantages over other digital signature algorithms, and the challenges of its adoption in Indonesia. The results show that ECDSA provides high cryptographic efficiency, maintains transaction authenticity and integrity, and supports a transparent decentralized system. The academic simulations include not only KYC processes, top-ups, transactions, validation by validators, and block recording, but also demonstrates the formation of an interconnected multi-level blockchain and tests scenarios for rejecting manipulated or invalid transactions. The contribution of this research lies not only in the theoretical review but also in the implementation illustrations that can be used as a basis for education and the initial development of blockchain-based digital payment systems. The research results show that ECDSA is capable of providing a high level of efficiency in the encryption and transaction verification process, maintaining data integrity and authenticity, and supporting a decentralized and transparent system. The academic simulations included the KYC process, wallet creation using ECDSA keys, balance top-ups through bank integration, transaction creation and validation, and block recording in the blockchain. Specifically, the simulations successfully demonstrated how new blocks are added to the chain by referencing the previous block's hash, as well as how transactions with corrupted signatures, manipulated amounts, or insufficient balances are automatically rejected by the validator consensus mechanism, maintaining system integrity. This research contributes not only theoretically, but also through conceptual representations that can be used as an educational foundation and for the initial development of blockchain-based digital payment systems in Indonesia.

This study aims to investigate the factors influencing the continuance intention of Al-Kautsar Senior High School students in using metaverse-based learning media. The background of this research lies in the rapid adoption of immersive technologies in education, while students’ levels of acceptance have not yet been fully understood. The objective is to identify the antecedents of satisfaction, which subsequently influence continuous intention. The research model examines the effects of perceived interactivity, perceived sociability, perceived enjoyment, perceived ease of use, perceived security, and social influence on satisfaction. A quantitative approach was employed by distributing questionnaires to students, and the data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that satisfaction is a very strong and statistically significant predictor of continuous intention to use metaverse applications (β = 0.716, p < 0.001). The six hypothesized antecedent variables were not found to have a significant individual effect on satisfaction. In conclusion, for digital native students at Al-Kautsar Senior High School, factors such as ease of use, interactivity, and enjoyment have shifted from being drivers of satisfaction to becoming basic expectations (hygiene factors). Satisfaction itself emerges as the primary determinant, likely influenced by more substantive elements such as content quality or pedagogical design rather than merely the technical features of the platform.

The results showed an increase in positive attitudes from 23.3% before education to 80.0% after. However, the statistical test indicated no significant relationship (p = 0.170). Nevertheless, education demonstrated potential in promoting positive attitude changes and remains important for continuous implementation.

Discomfort during pregnancy is a common experience resulting from physical, physiological, and psychological changes, yet it is often not well understood by pregnant women. Limited knowledge about normal bodily changes and pregnancy-related discomfort can reduce maternal comfort and increase anxiety. Counseling serves as an important educational strategy to improve pregnant women’s understanding, particularly within antenatal care services at primary health care facilities. This study aimed to examine the effect of counseling on pregnancy discomfort in improving mothers’ knowledge about changes during pregnancy. A quasi-experimental design with a one-group pretest–posttest approach was employed. The sample consisted of 50 pregnant women selected using a total sampling technique. Mothers’ knowledge levels were assessed before and after the counseling intervention using a structured questionnaire. Data analysis included univariate analysis to describe the distribution of knowledge levels and bivariate analysis using the Wilcoxon Signed Rank Test to evaluate differences before and after the intervention. The findings demonstrated a notable increase in knowledge following counseling, indicated by a shift from predominantly poor and moderate knowledge levels in the pretest to good knowledge in the posttest. Statistical analysis revealed a significant difference between pretest and posttest results (p < 0.05). In conclusion, counseling significantly improves pregnant women’s knowledge regarding pregnancy-related changes and discomfort.
