This study explores the intellectual and thematic evolution of green sukuk research within Islamic sustainable finance from 2015 to 2025. Using a hybrid methodological design that integrates the PRISMA-guided Systematic Literature Review with Watase Uake network analysis, the study identifies 17 core Scopus-indexed articles that collectively define the field’s conceptual and empirical development. Results reveal a three-phase evolution: (1) a formative stage emphasizing ethical legitimacy and Sharia compliance; (2) a transitional phase integrating pricing efficiency, market risk, and policy frameworks; and (3) a maturity phase characterized by econometric modeling, behavioral-finance integration, and sustainability governance. Thematic clusters extracted from bibliometric mapping include financial performance and market dynamics, institutional legitimacy and policy frameworks, behavioral intention and investor psychology, and technological innovation and ESG disclosure. Despite methodological advancement, the literature remains geographically concentrated in Malaysia and Indonesia and exhibits theoretical fragmentation across behavioral, financial, and institutional models. Findings highlight key research gaps involving contradictory evidence on yield–risk relationships, inconsistent behavioral determinants of investment intention, and insufficient integration of moderating or mediating mechanisms. The study advances theoretical pluralism by connecting the Theory of Planned Behavior (TPB), Institutional and Legitimacy Theory, and Resource-Based View (RBV) into an integrated model explaining how legitimacy, behavior, and strategic capability jointly drive green sukuk adoption. Policy implications emphasize the need for harmonized regulation, behavioral incentives, and digital transparency to strengthen credibility and accelerate sustainable-finance transformation in line with SDGs 7 and 13.

The rapid growth of social media as a primary channel for information dissemination has triggered a significant surge in the distribution of hoaxes, potentially damaging social order, instigating mass disinformation, and threatening national security. This research aims to design an intelligent algorithm for hoax detection by integrating a critical thinking approach into Natural Language Processing (NLP)-based text processing. The algorithmic model is built using a combination of linguistic features, argument logic, and cognitive indicators such as the detection of unsubstantiated claims, identification of source bias, and evidence testing. To ensure accountability and transparency of the system, an Explainable AI (XAI) approach is applied so that classification results can be understood by non-technical users. The research results show that integrating critical thinking significantly improves detection accuracy to 93.1%, with an increase in precision and recall for detecting hoaxes based on emotional narratives. Beyond technical aspects, this model aligns with the mandate of Law of the Republic of Indonesia Number 11 of 2008 concerning Information and Electronic Transactions (ITE Law), particularly Article 28 paragraph (1), which prohibits the dissemination of false and misleading news that harms the public. Therefore, this system is not only scientifically relevant but also supports law enforcement and strengthens digital literacy in the post-truth era. These findings are expected to be a strategic contribution to the development of an ethical, critical, and responsible digital ecosystem.

Rock stability and service life in geotechnical and mining engineering are highly dependent on the rock's mechanical and physical parameters, where the variation in sandstone grain size is a crucial intrinsic factor. This study aims to comprehensively analyze the correlation between sandstone grain size with uniaxial compressive strength (UCS) and resistance to weathering (Slake Durability Index) in samples taken from the Balikpapan and Pulau Balang Formations in the Samarinda area, East Kalimantan. The research methodology involved a series of standard laboratory tests, including rock physical properties analysis, grain size distribution analysis, UCS testing, and slake durability testing through three cycles. The test results show a significant correlation: sandstone with finer grain sizes and higher density consistently demonstrates greater UCS values and a higher Durability Index, indicating superior mechanical and physical resistance. Specifically, the Pulau Balang Formation exhibits a more compact structure and finer grain size, resulting in better durability values compared to the Balikpapan Formation. These findings are important as a geomechanical data basis for slope design planning, rock mass stability analysis, and material selection in infrastructure projects or mining operations involving both formations.

This study aims to determine the role of Community Service Program (KKN) students in increasing interest in learning Islamic Religious Education (PAI) at the Al-Muttaqin Foundation MDTA. The background of this study stems from the low enthusiasm and motivation of students in participating in religious lessons, so that learning innovations are needed that can rekindle their enthusiasm for religious values. KKN students, as part of the implementation of the Tri Dharma of Higher Education, have a social responsibility to contribute directly to society, one of which is through educational activities. In its implementation, students apply various creative, interactive, and fun learning methods, such as educational games, group discussions, and role-model-based approaches that make students more active and motivated. This study uses a descriptive qualitative method with observation, interview, and documentation techniques during the two-month activity. The results show that the presence of KKN students has a positive influence on increasing student interest in learning, seen from increased discipline, active participation, and curiosity about PAI materials. In addition to being teachers, students also play a role as moral guides who instill religious values ​​through positive behavior and habits.   

Holding a socialization activity to teach 6th grade students at SD 014662 the habit of saving money from an early age. This activity aims to foster students' interest in saving money. Character education, including learning about money and the habit of saving money from an early age, is the main basis for this activity because many elementary school students are still not interested in saving money. The main objectives of this outreach program are to raise awareness of the benefits of saving, encourage students to get into the habit of saving, train them in self-control, introduce them to basic financial services, and enhance their creativity by making piggy banks from recycled materials. The program implementation method is divided into several stages, namely coordination, media preparation, outreach, and piggy bank making. This activity was carried out face-to-face at SD 014662 Desa Perk.Gunung Melayu. The target of this activity was 6 sixth-grade students of SD 014662 aged between 11 and 12 years old. Various activities were carried out, including presenting material on the definition, benefits, and socialization of how to save money. In addition, there were also practical activities, namely making piggy banks from used cans and determining savings targets. The savings socialization activity was carried out smoothly and succeeded in arousing students' interest in saving money. They also gained a better understanding of the meaning, benefits, and methods of saving money. All sixth-grade students appeared enthusiastic and interested, listening attentively to the material and actively asking and answering questions. The activity of making and decorating piggy banks from used cans also successfully stimulated the students' creativity. In addition, students began putting their remaining pocket money into the piggy banks and setting savings targets, indicating a shift in habits from being consumptive to being more economical. From the results of these activities, it can be concluded that socializing the habit of saving from an early age with a practical and interactive approach is very effective in increasing interest and forming disciplined habits in managing children's money.

In the digital age, information travels quickly, which has made it easier to learn new things but also made it easier for false information to spread. In Indonesia, fact-checking efforts by online news sites like Kompas, Tempo, and Liputan6 have become very important in dealing with this problem. This study examines the linguistic and discursive strategies utilized in fact-checking articles published from 2022 to 2024 to foster critical literacy among readers. Utilizing the principles of Critical Literacy and Critical Discourse Analysis (CDA), the study examines five fact-checking texts addressing political, health, and social matters. The results show that all the articles follow the same story structure: they start with claims, then go into detail about the investigations, present evidence, and give final judgments. At the micro level, hedges, boosters, and evidential markers are used on purpose to change how certain and credible something is. At the meso level, discourse structures and intertextual references bolster institutional authority, whereas at the macro level, fact-checking serves as an educational instrument that promotes critical and contemplative reading habits. Overall, the study shows that fact-checking serves two purposes in Indonesia: it helps people check the accuracy of information and it helps people build their resistance to false information.

The low level of financial literacy among students, especially Generation Z, has become a serious concern that requires solutions to face the increasingly complex challenges of the modern economy. Many students still do not fully understand the importance of financial management and continue to exhibit high consumer behavior due to the lack of financial education provided from an early age. This community service activity aims to enhance students' understanding of the importance of financial literacy through the habit of saving, which can be started at a young age as a form of simple yet highly effective financial management. The methods used in this activity include interactive lectures, pocket money management simulations, group discussions, and educational quizzes designed to increase students' active participation. The results of the activity show an increase in students' awareness of the importance of saving, as well as their ability to manage personal finances in a more directed, wise, and responsible manner in everyday life. This shows that financial education based on saving habits can help students achieve better financial management in the future.

The low level of financial literacy in Indonesia, which only reached 49.68% according to the Financial Services Authority (OJK) in 2022, highlights the urgency of financial education from an early age. Children aged 11–12 are at an ideal developmental stage to understand basic financial concepts such as income, expenses, saving, and delayed gratification. This study aims to introduce financial literacy through an interactive learning medium in the form of a board game. Board games are chosen because they enhance children's engagement in learning while playing and serve as an alternative to excessive gadget use. Through gameplay, children practice financial decision-making by simulating buying and selling activities, managing expenses, and choosing to save. This approach also supports the development of children's self-efficacy, which refers to their belief in their ability to manage financial tasks. By applying this method, children are expected not only to understand the value of money but also to implement basic financial management skills in daily life. Educational board games offer an effective tool for instilling healthy financial habits from an early age.

Osteoarthritis is a degenerative joint disease whose exact cause is not yet fully understood. This condition is characterized by damage to the articular cartilage, resulting in pain, joint stiffness, decreased muscle strength, muscle spasms, and reduced functional activity of the patient. Several factors contribute to the development of osteoarthritis, including age, gender, race, genetic factors, smoking habits, history of trauma, type of occupation or physical activity, exercise habits, and obesity. The prevalence of osteoarthritis increases with age; among individuals aged 65–74 years, approximately 39% experience knee osteoarthritis and 23% experience hip osteoarthritis. In those over 70 years old, almost all individuals, both men and women, show symptoms of this condition. Osteoarthritis is a chronic progressive disease characterized by inflammation of the articular cartilage and synovial membrane, which causes persistent pain, joint stiffness, decreased muscle strength, and reduced mobility. Physiotherapy management for this condition aims to reduce pain, improve muscle strength, and enhance joint function. Common therapeutic modalities used include Shortwave Diathermy (SWD), Transcutaneous Electrical Nerve Stimulation (TENS), and the Hold Relax exercise technique, which helps relax muscles and increase joint range of motion

Work fatigue is one of the factors that contribute to decreased productivity and increased risk of occupational accidents. This study aims to analyze various factors associated with work fatigue among production workers at PT. X in 2025. The research employed an analytical quantitative design with a cross-sectional approach. The sample consisted of 53 respondents selected using total sampling. Data were collected through questionnaires covering worker characteristics (age, nutritional status, medical history, smoking habits, years of service, and work stress) as well as levels of work fatigue. Data analysis was conducted using the chi-square test. The findings revealed that 56.6% of workers experienced high levels of fatigue. There were significant associations between age (p=0.023; PR=1.836), nutritional status (p=0.021; PR=1.786), medical history (p=0.025; PR=1.789), smoking habits (p=0.039; PR=1.706), years of service (p=0.015; PR=1.912), and work stress (p=0.032; PR=0.574) with work fatigue. The results indicate that workers who are at-risk age (≥35 years), have abnormal nutritional status, a history of illness, smoking habits, and longer years of service are more likely to experience work fatigue. However, high work stress showed a negative relationship, suggesting a protective effect against fatigue. In conclusion, there is a relationship between age, nutritional status, medical history, smoking habits, years of service, and work stress with work fatigue among production workers at PT. X.

The findings show that children begin to understand the concept of saving not only as storing money but also as a step toward achieving future goals. Furthermore, the active participation of parents and mentors plays an important role in building consistent saving habits. Through this financial literacy program based on savings awareness, it is expected to create a generation that is disciplined, responsible, and capable of managing finances properly from an early age.

This research analyzes the fundamental conflict between state regulation and Sharia principles regarding cryptocurrency in Indonesia, aiming to explore the views of Islamic scholars and the legal perspective in the Qur'an and its interpretations. Cryptocurrency has become a popular investment trend, especially among the youth. While the Bank Indonesia (BI) prohibits its use as a legal payment instrument, its trading activity is legalized as an investment asset under the supervision of OJK and BI. Conversely, the MUI Fatwa and the majority of scholars declare crypto transactions as forbidden (haram) due to the presence of elements prohibited in Islamic economics: riba (usury) and gharar (uncertainty). Gharar is linked to the extreme price volatility that encourages speculation (maysir) and the non-physical nature of crypto. Riba, on the other hand, is associated with the potential for unfair profit in lending and staking mechanisms. This prohibition is rooted in the interpretation of the Qur'an (QS. Al-Baqarah: 275 and QS. An-Nisa: 29), which strictly forbids riba and consuming others' wealth through bathil (unlawful) means. Consequently, although legally accepted as an investment asset, many scholars view crypto as violating the principles of justice and transparency in Islamic economics.

Hypertension is a non-communicable disease that can be life-threatening, especially in the elderly. According to the WHO, more than 15 million people aged 30–69 years die each year from non-communicable diseases. This study aims to analyze factors influencing the incidence of hypertension in the elderly, including smoking, stress levels, culture, diet, exercise, and coffee drinking habits. This research method used a quantitative approach with a cross-sectional design. The population was 738 elderly people, with a sample size of 259 elderly people, and random sampling was used. Data analysis was performed using univariate, bivariate using the Chi-Square test, and multivariate using the Pearson correlation test. The results of this study such as Smoking with hypertension: There is a significant influence (p = 0.002), stress level There is a significant influence (p = 0.002), Culture There is a significant influence (p = 0.010), Eating patterns with hypertension are significant (p = 0.049), Exercise There is a significant influence (p = 0.003), drinking coffee with a significant influence (p = 0.048). Multivariate analysis shows that culture (p = 0.003; r = 0.177) and coffee drinking habits (p = 0.022; r = 0.139) are the most influential factors on elderly hypertension, while other factors are not significant. This study shows that smoking, stress levels, culture, diet, exercise, and coffee consumption are significantly associated with hypertension in the elderly. However, a multivariate analysis revealed that cultural factors and coffee drinking habits were the most dominant factors influencing hypertension, while other factors had no significant effect after being controlled for. Therefore, efforts to prevent and control hypertension in the elderly need to focus on changing cultural practices that are less conducive to health and regulating coffee consumption, while still considering the implementation of a healthy lifestyle overall.

Teachers’ religious understanding plays a vital role in shaping early childhood religious attitudes through systematic, consistent, and contextual guidance. This study aims to analyze the implementation of teachers’ religious understanding in fostering children’s religious attitudes at Yayasan Taman Pendidikan TPQ/RA Wahyu Medan. The research applied a qualitative method with a descriptive approach, using in-depth interviews, observations, and documentation to explore teachers’ experiences in religious nurturing practices. The findings revealed that teachers have successfully integrated religious values into learning activities, such as collective prayers, memorization of short Qur’anic surahs, greeting habits, and prayer exercises. However, challenges remain, including limited use of interactive learning media and low parental involvement in supporting religious habituation at home. These findings imply that teachers’ religious understanding should be enhanced through continuous training and strengthened collaboration with parents to optimize the fostering of children’s religious attitudes. This study contributes to the development of early childhood education, particularly in strengthening character education based on religious values.

This community outreach activity was conducted at the Wahyu TPQ/RA Foundation, focusing on the implementation of religious character education through daily habituation activities for early childhood. The main issue behind this activity is the importance of instilling religious values ​​from an early age to shape a generation with noble morals and Islamic character. The method used was a qualitative method with a participatory approach, through observation, interviews, and documentation during religious habituation activities such as prayers before and after studying, reading short surahs, practicing congregational prayers, and Friday Infaq activities. The results of the activity showed a significant increase in children's involvement in religious activities and their consistency in carrying out positive habits. Children became more accustomed to prayer, their manners improved, and an awareness of sharing emerged through infaq activities. These findings are in line with the theory of habituation (habit formation), which emphasizes repetition as a strategy for forming character. This activity contributes to the development of science in the field of early childhood education, particularly in the aspect of religious character education, and can be a model of good practice that can be replicated by similar educational institutions.

Hypertension is a "silent disease" with a high prevalence that can be triggered by modifiable risk factors such as stress and smoking. Sei Langkai Community Health Center shows the highest hypertension service rate (20.12%) in Batam City with Sei Langkai Village having 50% of hypertension sufferers from the health center's working area. The purpose of this study was to analyze the relationship between stress and smoking with the incidence of hypertension in Sei Langkai Village, the Working Area of ​​UPTD Sei Langkai Community Health Center, Batam City. This research method is an analytical observational study with a cross-sectional design. The accessible population is residents aged >17 years in RW 17 RT 05 Sei Langkai Village (334 people). A sample of 75 respondents was selected using a cluster random sampling technique. Data collection used the Perceived Stress Scale (PSS) questionnaire to measure stress and the Fagerstrom Test for Nicotine Dependence (FTND) to measure smoking dependence, as well as blood pressure observations. Data analysis used the chi-square test and Spearman correlation. The results showed a significant association between stress and hypertension (p=0.001; PR=5.688; 95% CI: 2.200-14.705). Of the 47 respondents experiencing stress, 87.2% had hypertension. There was a significant association between smoking and hypertension (p<0.001; r=0.585). Of the 28 respondents with heavy smoking habits, 96.4% had hypertension. The study concluded that stress and smoking are significantly associated with hypertension. Respondents with stress had a 5.688-fold higher risk of developing hypertension. The more severe the smoking habits, the higher the risk of hypertension.

Real analysis is one of the main branches of mathematics that serves as a fundamental foundation for the development of science and technology. This study emphasizes the understanding of basic concepts such as real numbers, limits, continuity, the principle of mathematical induction, as well as deductive and axiomatic approaches as a strong framework for mathematical proofs. This research employs the Systematic Literature Review (SLR) method by examining articles and journals related to both the theoretical aspects and the implementation of real analysis in solving mathematical problems. The findings indicate that the application of Polya’s method, visualization through demonstration, and the use of modern technology such as augmented reality (AR) can enhance the effectiveness of real analysis learning. These approaches help students connect abstract concepts with real applications, thereby strengthening logical, systematic, critical, and rigorous thinking skills. However, several learning difficulties are also identified, including the complexity of the material, weak learning habits, social influences, and inappropriate teaching strategies. Therefore, more applicative, interactive, and contextual learning strategies are needed to support the achievement of learning objectives. The conclusion of this review highlights that the integration of theoretical understanding, problem-solving methods, and innovative technology is a strategic step to improve students’ thinking quality in real analysis courses. Thus, real analysis is not only positioned as a theoretical subject but also as a medium for developing problem-solving abilities and higher-order thinking skills that are relevant to both academic needs and real-world applications.

Menstrual cycle disorders can negatively impact athletic performance. A combination of irregular eating patterns and intense training can increase the risk of such disturbances. Factors influencing menstrual cycle irregularities include nutritional status, physical activity, dietary habits, stress levels, smoking, hormonal medication use, and endocrine disorders. A study conducted in Semarang found that 28.8% of female athletes experienced menstrual cycle issues. This research aims to investigate how physical activity and food intake affect menstrual cycle disorders among adolescent volleyball athletes in Kudus Regency. The methodology employed was an observational analytical study with a cross-sectional approach, selecting 46 respondents using purposive sampling techniques. The IPAQ and SQFFQ questionnaires were used as research instruments. Data were analyzed using bivariate analysis with the Chi-Square test. The results indicated that the majority of athletes had a high level of physical activity (76.1%), while 50% were categorized as having severe food intake deficits. Additionally, 78.3% of athletes experienced menstrual cycle disturbances, which included 36 individuals. Bivariate analysis revealed that physical activity influenced the menstrual cycle of adolescent volleyball athletes (p-value = 0.045), and dietary intake also had an effect (p-value = 0.000). Therefore, both physical activity and eating patterns significantly impact menstrual cycle disorders among adolescent volleyball athletes.
