The increasing integration of Cyber physical Systems (CPS) into industrial environments has highlighted the need for secure, scalable, and efficient cryptographic key management systems. Traditional centralized key management protocols are often limited by vulnerabilities such as single points of failure, scalability issues, and significant overhead. Blockchain technology presents a promising solution to these challenges by leveraging decentralization, immutability, and transparency to enhance security and efficiency in CPS. This study investigates the use of blockchain based cryptographic key management systems, focusing on smart contracts for automated key distribution and rotation. Experimental results demonstrate that blockchain based systems significantly improve system integrity, auditability, and resilience, offering enhanced protection against cyber-attacks and reducing the risks associated with centralized systems. Blockchain’s decentralized architecture eliminates the need for a central authority, making it more resistant to tampering and operational failures. Additionally, smart contracts automate the key management process, improving efficiency while maintaining a high level of security. The study also evaluates the impact of blockchain on communication performance, finding that it reduces latency and overhead by automating processes and eliminating the need for centralized control. Despite these advantages, challenges such as scalability, latency, and integration with legacy systems remain. The study concludes by suggesting future research directions, including the development of lightweight blockchain protocols tailored for industrial applications and the integration of blockchain with emerging technologies like Artificial Intelligence (AI) to further enhance key management in CPS. Blockchain based solutions have the potential to transform the security landscape of industrial environments, offering greater robustness, reliability, and trust.

Low back pain (LBP) is one of the most common musculoskeletal complaints globally and is the main cause of decreased work productivity. One of the risk factors that has been widely studied in the literature is prolonged sitting duration. Prolonged sitting activities cause increased static pressure on the lumbar spine, fatigue of the supporting muscles, as well as a decrease in local blood flow that can trigger chronic pain. This study is a literature review with a meta-analytical approach that aims to analyze the relationship between long-term sitting and the incidence of LBP. The review process was carried out following PRISMA guidelines through searches on PubMed, Scopus, ScienceDirect, and Google Scholar databases for publication in 2020–2025. Of the 20 previous studies analyzed, most showed a positive association between sitting time and an increased risk of LBP, both in adults, adolescents, and children. Sitting for more than 6 hours per day increases the risk of LBP by 33%, especially in individuals with low physical activity. In addition, longer sitting durations with poor posture and minimal active rest were found in the group of office workers and professional drivers who had a high prevalence of LBP. Physical activity has been shown to play a protective role against the risk of LBP, while ergonomic interventions such as lumbar support can reduce pain complaints. Although most studies were observational, the consistency of results supports the importance of prevention through reduced sitting time, increased physical activity, and ergonomic work environment settings. These findings provide a scientific basis for multidimensional interventions to effectively reduce the incidence of LBP.  

This study aimed to analyze differences in body composition among adult women across three regions with distinct sociocultural and environmental characteristics: Baduy Luar (rural–traditional), Salatiga (semi-urban), and Kota Bambu (urban). Using a cross-sectional design, the study involved 268 participants and assessed total body fat, visceral fat, subcutaneous fat, and skeletal muscle mass using the OMRON HBF-370 analyzer. Significant differences were observed across most body composition parameters (p < 0.001). Women living in the urban area exhibited the highest levels of total fat, visceral fat, and subcutaneous fat, reflecting the influence of urbanization and sedentary lifestyle on adiposity. Conversely, women in the rural–traditional community demonstrated the highest skeletal muscle mass across all body regions, consistent with their physically demanding daily activities and traditional dietary patterns. These findings highlight the substantial role of environmental context in shaping metabolic health and cardiometabolic risk. Targeted public-health interventions—such as structured physical-activity promotion and nutrition education in urban populations, and preservation of active lifestyles in rural communities—are recommended. Longitudinal studies are warranted to clarify causal pathways and further characterize metabolic determinants.

Plastic waste is a form of solid waste originating from synthetic polymer materials that are difficult to decompose naturally and pose serious threats to environmental sustainability. Its accumulation continues to increase, causing pollution of soil, water, and ecosystems. In general, public attention is often limited to waste disposal and management activities without addressing preventive measures or innovative solutions at the source of the problem. This study aims to increase public awareness of plastic waste processing as an alternative approach to reducing the growing volume of plastic waste generated daily. One promising method explored in this research is the utilization of plastic waste as a raw material for producing environmentally friendly construction bricks. The study applied a simple descriptive experimental approach through direct practical activities, including the collection of plastic waste, processing and melting procedures, molding processes, and drying stages. The results demonstrate that plastic waste can be transformed into bricks with adequate physical strength and mechanical properties that comply with basic building standards. Therefore, this method has the potential to support sustainable waste management while providing alternative construction materials.

Environmental pollution in coastal areas continues to be a critical issue, particularly in regions with high tourism activity such as Pantai Baru Seliper Ate in Sumbawa.

The method consisted of short religious-based environmental education, a collaborative beach-cleaning activity, and a reflective session designed to reinforce ecological and spiritual awareness. The results showed a significant increase in students’ knowledge of environmental ethics, Islamic principles related to cleanliness, and practical skills in waste identification and sorting. The program also succeeded in improving the physical condition of the beach and fostering collective responsibility among participants. These findings indicate that integrating environmental education with Islamic values and hands-on activities can effectively enhance environmental awareness and support sustainable behavior among young people.

Having a child with an intellectual disability requires parents to face greater challenges in parenting, encompassing not only physical needs but also emotional and social aspects. This study aims to explore the resilience of parents of children with intellectual disabilities and the factors that influence it. Parental resilience encompasses the ability to survive, adapt, and thrive despite facing high levels of psychological stress. This study used a narrative literature review method, reviewing 11 international and national journal articles published between 2015 and 2025. The results indicate that psychological stress, such as anxiety, stress, and frustration, is often experienced by parents, but high resilience can mitigate the negative impact of this stress. Factors influencing resilience include the individual characteristics of parents, the characteristics of children with intellectual disabilities, and social and environmental support. Good resilience not only supports child development but also the well-being of parents. Based on these findings, this study suggests the importance of social support and the formation of a community of parents to share experiences and provide emotional support.

Early childhood development (0–6 years) is a critical period that shapes a child’s physical, cognitive, socio-emotional, language, and moral growth. The family, as the first educational environment, plays a vital role in shaping the child’s character and adaptive skills, particularly through parent–child interactions. In Muslim communities, child-rearing focuses on not only psychological aspects but also reinforcing religious values through Islamic Parenting, which is based on the principles of rahmah (compassion), uswah (exemplary behavior), guidance, and ‘adl (justice), as outlined in the Qur’an and Hadith. This study uses a qualitative literature review to analyze the role of Islamic Parenting in early childhood development, highlighting the significance of these values. The review shows that Islamic Parenting plays a crucial role in optimizing children’s holistic development, including cognitive, social, emotional, moral, and spiritual aspects. Key components of this model include parental exemplification, compassion, religious education, positive behavior habituation, and cognitive stimulation through educational interactions. This model can be implemented through daily practices such as prayers, storytelling, and character reinforcement. In conclusion, Islamic Parenting fosters not just biological caregiving but also character, morality, and spirituality, preparing children for contemporary challenges.

Gender inequality in terms of safety in public spaces is a crucial issue in Indonesia. This research background is driven by the high rate of violence against women, reaching 330,079 cases in 2024, and reinforced by a patriarchal culture that perpetuates gender hierarchy. This study uses a qualitative method with a literature study approach to analyze the root causes and impacts of gender inequality on women's sense of security in public spaces. The results indicate that the disparity manifests in various dimensions, such as women-unfriendly urban infrastructure (e.g., inadequate lighting), security threats in urban areas, and the high rate of gender-based violence where 80.1% of the victims are women. The discussion reveals that this inequality impacts not only physical safety but also psychological well-being, economic security, and access to public spaces. This research concludes that a multidimensional approach encompassing infrastructure improvement, strengthening legal protection, changing social norms, and economic empowerment is required to create an inclusive, equitable, and safe public environment for all genders.

Background: Sleep disorders in adolescents are a significant health problem, with a global prevalence reaching 57.8% and particularly high rates in several cities in Indonesia. Poor sleep quality negatively impacts physical health, such as the risk of cardiovascular disease and anemia, as well as mental and cognitive health. Sleep behavior is influenced by a dynamic interaction between personal and environmental factors, as explained in Social Cognitive Theory (SCT). Research Objective: To identify the determinants of sleep deprivation in adolescents, specifically individual and environmental factors, based on a Social Cognitive Theory (SCT) perspective through a literature review from 2019 to 2025. Method: This study utilized a literature review. To obtain research data, the authors searched for scientific articles through Google Scholar, PubMed, and ScienceDirect databases, then analyzed 10 articles that met the inclusion criteria, published between 2020 and 2025. Results: Factors significantly associated with adolescent sleep quality were identified, with individual factors being the most dominant determinant (found in 7 studies), including academic stress and smartphone addiction. Furthermore, a positive association was found with environmental factors (found in 4 studies), such as bright lighting, noise, and uncomfortable room temperature. Conclusion: Within the framework of Social Cognitive Theory, adolescent sleep quality is the result of a reciprocal interaction between personal factors (perceived stress and self-control over gadgets), the physical environment, and sleep behavior. Individual factors such as stress and nighttime gadget use reduce self-efficacy for regular sleep, which is exacerbated by an unfavorable environment.

The increasing integration of digital technology into the daily lives of Generation Alpha has contributed to reduced physical activity, highlighting the need to understand the factors shaping children’s movement behaviors. This study employed a quantitative correlational approach to examine the relationship between parental educational background and the physical activity levels of students aged 13–15 at SMP 1 Waru Sidoarjo. Data were collected through a parental education questionnaire and the PAQ-C instrument, which assesses children’s physical activity over the past seven days. A total of 45 respondents participated, and the data were analyzed using Pearson or Spearman correlation tests, depending on distribution. The findings revealed a positive and statistically significant—though weak—association between parental education and children’s physical activity levels. Parents with higher education tend to promote more active lifestyles by regulating screen time, providing access to sports facilities, and modeling healthy behaviors. These results underscore the essential role of families in developing healthy routines among Generation Alpha and the need for educational initiatives to enhance parental awareness of physical activity in an increasingly digital environment.

The scarcity of real-world data in Air-Conditioning (AC) fault diagnosis necessitates the use of synthetic data; however, rule-based synthetic datasets often suffer from a significant sim-to-real domain gap. To address this, we propose a Model-Data Coevolution (MDC) framework that employs a Simulated Annealing (SA) controller to optimize augmentation parameters. We introduce a novel technique, Stochastic Feature Decoupling (SFD), which applies independent noise to raw and derived features, contrasting it with traditional Logically-Consistent Augmentation (LCA). Empirical results show that SFD significantly outperforms LCA, achieving a weighted F1-score of 0.93 and increasing NORMAL class recall to 82%. We demonstrate that by breaking deterministic feature links, SFD acts as a robust regularizer, utilizing "physically impossible" data to enhance generalization in complex real-world environments.

The data obtained were analyzed using content analysis techniques to identify patterns, concepts, and relationships between variables. The results of the community service indicate that the introduction of woodball as an alternative sport has significant potential to increase sports literacy, support character development, develop motor skills, and encourage more inclusive and sustainable sports development in the school environment.

Soil contamination by hydrocarbons, pesticides, heavy metals, and complex pollutants is rapidly increasing and degrading essential ecosystem functions. Physical or chemical treatments offer faster results, yet they are often costly, energy-intensive, and risk disrupting soil biological integrity without fully eliminating pollution sources. Microorganism-based bioremediation provides a more sustainable alternative by utilizing microbial metabolism to degrade or immobilize pollutants into less toxic and less mobile forms. This article presents a structured literature review on the roles and applications of microorganisms for bioremediation of contaminated soils, covering comparisons between single isolates and microbial consortia, dominant biological mechanisms, and ecological challenges in field application. A Systematic Literature Review approach was applied, using narrative synthesis and thematic clustering of national and international journals published between 2020 and 2025. The review indicates that single microbial isolates are commonly selected for specific pollutant targets, whereas microbial consortia are preferred for mixed or persistent contaminants due to metabolic synergy that enhances microbial adaptability and stepwise pollutant breakdown in highly polluted soils. Adaptive mechanisms such as EPS production and biofilm formation contribute to microbial resilience under stress and help retain contaminants within the soil matrix. Key challenges identified include inoculum stability under extreme conditions and limited microbial access to pollutants trapped in micro-soil pores. The findings highlight that microbial selection strategies must be tailored to pollutant characteristics and soil environmental conditions, while also emphasizing the potential of biofilm-based systems and organic carriers to support broader field implementation of microbial bioremediation.

 Communicable diseases remain one of the leading public health burdens in Indonesia, particularly in densely populated residential areas and communities with inadequate sanitation. Poor housing conditions including insufficient ventilation, overcrowding, excessive humidity, inadequate lighting, and improper waste and wastewater management have been shown to increase the risk of respiratory infections, diarrhea, and other environment-related diseases. This literature review aims to identify effective environmental health strategies for preventing communicable diseases by synthesizing findings from 11 scientific articles published between 2014 and 2025. The review shows that basic sanitation, indoor air quality, waste management, and the implementation of the Community-Based Total Sanitation (STBM) program are key determinants in reducing disease incidence. Additionally, successful interventions depend heavily on clean and healthy living behaviors (PHBS) and active community participation. These findings highlight the importance of a comprehensive approach that integrates physical environmental improvements, health education, and community empowerment to create healthy settlements and sustainably reduce the risk of communicable diseases.
