rmance demands indicate that training programs alone are insufficient to produce optimal athletic performance; therefore, sports nutrition strategies become a crucial component in supporting athletes’ physiological adaptation processes. The research problem addresses how sports nutrition contributes effectively to improving the power and endurance of volleyball athletes based on recent scientific evidence. This study aims to systematically analyze the contribution of sports nutrition to enhancing the physical capacity of volleyball athletes through a scientific literature review approach. The research method employs a Systematic Literature Review (SLR) using the PRISMA framework to examine articles indexed in Scopus and SINTA published between 2015 and 2024. The identification process yielded 312 articles, followed by a rigorous screening and eligibility assessment that resulted in 22 articles meeting the inclusion criteria, with 10 core studies analyzed in depth to obtain a synthesis of relevant scientific findings. The results indicate that carbohydrate periodization of 6-8 g/kg body weight per day contributes to an improvement in vertical jump performance by approximately 3-6%, while optimal protein intake of 1.6-2.2 g/kg body weight per day increases peak power by about 4-8%. Creatine monohydrate supplementation of 3-5 g per day has been shown to enhance explosive power by 5-12%, whereas beta-alanine supplementation improves anaerobic work capacity by 8-14%. Hydration strategies and carbohydrate regulation also contribute to an increase in VO₂max by 2-5% and reduce the fatigue index by 6-10%. The findings confirm that sports nutrition functions as an essential mediator between training stimuli and the neuromuscular as well as metabolic adaptation responses of athletes. The novelty of this study lies in its conceptual synthesis that positions nutritional periodization as an evidence-based integrative strategy for sustainably optimizing the power and endurance of volleyball athletes.
Abstract:Chronic pain represents a major global health burden and often remains resistant to conventional pharmacological treatment, prompting the exploration of alternative therapeutic strategies. Electroencephalographic (EEG) neurofeedback…
eurofeedback has emerged as a non-invasive neuromodulatory intervention that enables patients to self-regulate brain activity and potentially alleviate persistent pain symptoms. This systematic review addresses the research problem of inconsistent evidence regarding the clinical efficacy and underlying mechanisms of EEG-based neurofeedback for chronic pain management in adults. A comprehensive analysis of 80 studies involving adults with chronic pain lasting at least three months was conducted, examining neurofeedback protocols, clinical pain outcomes, neurophysiological changes, secondary benefits, and methodological quality. Findings revealed heterogeneous results, with several studies reporting statistically significant and clinically meaningful pain reduction, particularly in conditions such as chemotherapy-induced neuropathy, fibromyalgia, and chronic back pain. Observed neurophysiological changes, including increased alpha power and modified connectivity in pain-related brain regions, were sometimes associated with clinical improvement, alongside reported benefits in sleep quality, mood, and overall well-being. However, evidence from sham-controlled randomized trials showed no significant differences between intervention and control groups, highlighting methodological limitations and challenges in blinding procedures. The review concludes that EEG neurofeedback is a safe and feasible intervention with potential therapeutic value for chronic pain, although current evidence remains inconsistent. The novelty of this study lies in its integrative evaluation of clinical outcomes, neurophysiological mechanisms, and protocol-specific effects, while emphasizing the need for personalized approaches, biomarker identification, and rigorous experimental designs to clarify efficacy and optimize treatment implementation.
Abstract:Infant sleep quality is a fundamental biological need that plays a crucial role in growth and neurological development; however, sleep disturbances remain common among infants aged 3-6 months and are often overlooked by…
parents. This condition poses risks to physical health, emotional well-being, and overall infant development. This study aims to analyze the effect of baby massage on sleep quality among infants aged 3-6 months at Babycare Bondowoso and to identify differences in sleep quality before and after the intervention. The study employed a quantitative approach with a quasi-experimental one-group pretest-posttest design involving 40 infants selected through total sampling. Data were collected using questionnaires and observation sheets, then analyzed using the Wilcoxon test. The results showed that prior to the intervention, 87.5% of infants experienced poor sleep quality, whereas after the intervention, all infants (100%) demonstrated improvement to good sleep quality. Statistical analysis indicated a p-value of 0.00, which is lower than 0.05, confirming a significant effect of baby massage on infant sleep quality. These findings demonstrate that baby massage effectively improves sleep duration, comfort, and stability through physiological relaxation mechanisms. The novelty of this study lies in providing empirical evidence of the effectiveness of baby massage as a non-pharmacological intervention that is simple, safe, and can be independently applied by parents while offering holistic benefits for infants. The findings are expected to serve as a basis for developing health education and improving infant care practices.
Abstract:Students in early adulthood often face academic, social, and personal pressures that cause fluctuations in mood and affect mental health and psychological well-being. The main issue addressed in this study is students’ low…
low ability to recognize, understand, and manage emotions adaptively, highlighting the need for effective strategies to enhance emotional awareness. This research investigates the effectiveness of self-reflection and journaling in improving students’ mood awareness. A combination of descriptive qualitative and quasi-experimental pretest-posttest designs was used, with instruments including mood scales, reflection guidelines, and students’ daily journals. Results showed a 32% increase in the average mood awareness score, a decrease in students with low awareness from 64% to 18%, and an increase in high awareness from 14% to 56%. Active participation was observed in 78% of students, while 85% consistently documented their emotional experiences, 88% reported feeling relieved, and 76% could identify recurring emotional patterns. The intervention also promoted the development of more adaptive self-regulation strategies, such as time management, adequate rest, and social support, increasing from 21% before the intervention to 69% afterward. Sustainability of practice was indicated by 61% of students intending to continue journaling independently and 57% integrating it into their daily routines. The novelty of this study lies in the integration of self-reflection and journaling as a practical, systematic, and sustainable approach to enhance emotional awareness and psychological well-being. The findings confirm that a simple yet structured intervention can create significant improvements in emotion management and adaptive behaviors among students.

ical practices are implemented by the stone carving community in Muntilan, Magelang Regency, as an alternative educational model capable of transmitting knowledge across generations in a sustainable manner. The study employs a qualitative approach using a case study method to explore community-based learning processes through family apprenticeship, direct observation, and practical experience that integrates technical skills, aesthetic sensitivity, spiritual values, and Javanese philosophy. The findings reveal a distinctive learning ecology that emphasizes the internalization of tacit knowledge, character formation, and the close relationship between learning processes and socio-cultural life. The community also demonstrates adaptive resilience through its ability to adopt innovation without abandoning core cultural principles. The conclusion confirms that ethnopedagogical practices among the Muntilan stone carvers represent an effective and relevant contextual education model to support the preservation of intangible cultural heritage while addressing the challenges of modern education. The novelty of this study lies in the integration of ethnopedagogy with traditional craft practices as a holistic and sustainable non-formal education system, as well as its contribution to the discourse on decolonizing education and strengthening culturally based vocational education policies.
Abstract:The development of digital technology over the past two decades has revolutionized human communication, social interaction, and the formation of both individual and collective identities in a global context. Digital media…
a no longer merely function as communication tools but have become socio-cultural spaces that actively shape values, norms, symbols, and everyday practices. This phenomenon raises research questions regarding how cultural transformation and identity construction are influenced by the dominance of digital technology, as well as how social media and platform algorithms shape cultural visibility and digital identities. This study employs a qualitative approach through a critical narrative literature review, synthesizing theories of network society, mediatization, cultural globalization, digital capitalism, and digital identity. The analysis focuses on four key issues: cultural digitalization, the role of social media in identity formation, the emergence of hybrid identities, and platform power in determining cultural representation. Findings indicate that digital technology has ambivalent effects: it expands spaces for cultural expression, enhances public participation, and provides opportunities for marginalized groups to represent their identities; however, global platform dominance drives cultural homogenization, identity commodification, and inequitable symbolic representation. The novelty of this study lies in integrating a critical perspective on the influence of algorithms and digital capitalism in identity formation, which has rarely been addressed comprehensively in digital cultural studies. These findings offer theoretical contributions to media and cultural research as well as practical implications for understanding identity representation in the global digital era.
Abstract:The phenomenon of increasing consumption of homoromantic fiction content among early adult women has given rise to the term Fujoshi, which is often directly associated with support for LGBT issues, although such an interpretation…
pretation does not necessarily reflect individuals’ attitudes in a comprehensive manner. This study is grounded in the need to understand the attitudes of early adult Fujoshi in a more nuanced and non-simplistic way, particularly through the framework of attitude theory encompassing cognitive, affective, and conative dimensions. The research problem focuses on how Fujoshi aged 18-40 interpret, experience, and express their attitudes toward homoromantic fiction content and its relationship to social values and norms in real life. This study employed a descriptive qualitative approach using in-depth interviews with three Fujoshi informants who are members of the XX fan chat group. The findings indicate that social media and peer networks play a significant role in the process of becoming a Fujoshi, as well as in shaping relatively intensive and repetitive patterns of content consumption as a form of emotional entertainment. Cognitively, the informants recognize that homoromantic fiction is related to LGBT issues; however, at the affective level, their interest is primarily driven by the uniqueness of the narrative structure and character dynamics rather than by sexual orientation itself. In the conative dimension, most informants do not demonstrate a tendency to support LGBT practices in real life; some even hold conservative views and display critical awareness of the potential negative impacts of their hobby, which they perceive as not fully aligned with prevailing social norms. The study concludes that Fujoshi attitudes are complex, ambivalent, and highly contextual. The novelty of this research lies in revealing a clear differentiation between the consumption of homoromantic fiction as a form of symbolic entertainment and individuals’ value positions toward social reality, which are often normatively conflated in previous assumptions.
Abstract:This study was conducted to evaluate the quality of the electrical installation at Budi Bakti School Building in Samarinda by emphasizing aspects of reliability, safety, energy efficiency, and compliance with applicable…
electrical installation standards. The research approach involved field surveys to obtain empirical data, measurements of lighting intensity, calculations of the required number of lighting points according to the function and characteristics of each room, as well as technical analysis of installation components, including conductors and protection systems. All observed data were compared with theoretical calculations to identify the level of conformity as well as potential deviations that could cause problems. The findings indicate that although the electrical installation remains operational, there are significant discrepancies, particularly in the distribution of lighting intensity, the number of lighting points, and the selection and placement of protective components that do not fully meet the standards. These discrepancies affect the optimality of lighting, reduce user comfort, and present potential safety risks. Therefore, this study recommends adjustments to the installation design, prioritizing the optimization of the lighting system, the use of standard-compliant components, and the implementation of energy efficiency principles as part of a comprehensive improvement effort. The implications of these findings highlight that regular evaluations and updates of electrical installations in educational buildings are essential to create a safe, comfortable, and productive learning environment. Thus, the results of this research not only provide practical contributions for school management but also offer a scientific basis for developing technical standards of electrical installations that are more responsive to educational needs.
Abstract:Stunting remains a crucial public health issue in Indonesia as it has multidimensional impacts on physical growth, cognitive development, productivity, and the long-term quality of human resources. This study aims to analyze…
lyze the potential application of predictive Artificial Intelligence (AI)-based Wearable Health Technology in preventing child stunting, with an emphasis on the integration of technology into the health system, socio-cultural interrelations, and ethical dimensions that need to be anticipated. The research employed a qualitative approach through a systematic literature review, analysis of national health policies, and examination of reports on the implementation of digital health technologies related to child health. The results indicate that wearable devices are effective in recording health indicators in real-time, while predictive AI algorithms enable early detection of stunting risks, allowing interventions to be carried out quickly, accurately, and in a personalized manner. However, the success of implementation is highly dependent on the support of the digital health ecosystem, including adaptive regulations, infrastructure readiness, digital literacy among communities, as well as multi-stakeholder collaboration involving the government, medical professionals, the technology industry, and families. This study affirms that the integration of Wearable Health Technology and predictive AI is not merely an additional tool in medical services, but rather a representation of a health system transformation towards a more preventive, predictive, precise, and participatory paradigm. Thus, the utilization of evidence-based digital innovations has the potential to strengthen the effectiveness of stunting prevention programs in Indonesia while accelerating the achievement of national health development targets within the context of technological disruption and global dynamics.
