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.

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:Stunting is a chronic nutritional problem that remains a serious challenge to child health because it is associated with impaired physical growth, cognitive development, and the quality of human resources in the future.…
This condition is influenced by inadequate nutritional intake, particularly during the first 1,000 days of life, which plays a critical role in determining the quality of child growth. Exclusive breastfeeding is considered an important factor that contributes to meeting nutritional needs and strengthening the immune system of children. The research problem focuses on the relationship between breastfeeding practices and the degree of stunting among children aged 1-5 years in the working area of Sempol Community Health Center, Bondowoso Regency, in 2025. The study employed a quantitative approach using an analytic survey design with a population consisting of all stunted toddlers in the area. A sample of 75 respondents was selected using a proportionate stratified random sampling technique. Data were collected through questionnaires and observation sheets that assessed breastfeeding practices and the level of stunting based on the height-for-age (HFA) indicator. The results show that 72% of children received exclusive breastfeeding, while the remainder received partial breastfeeding or were not exclusively breastfed. The distribution of stunting severity indicates that 57.3% of children experienced mild stunting, 34.7% moderate stunting, and 8% severe stunting. The Chi-Square statistical test produced a p-value of 0.003 (p < 0.05), indicating a significant relationship between breastfeeding practices and the degree of stunting. These findings demonstrate that the nutritional quality and antibodies contained in breast milk play an important role in supporting optimal child height growth. The novelty of this study lies in its analysis of the relationship between breastfeeding practices and the severity of stunting within the specific context of a local community health center area that has rarely been examined in detail. The findings emphasize the importance of health education for mothers and strong family support to strengthen exclusive breastfeeding practices as a strategic effort to prevent stunting.

Abstract:Islamic Religious Education in higher education frequently experiences a reduction of meaning due to the separation between the mastery of empirical sciences and the cultivation of spirituality, resulting in its position…
being perceived as a complementary course with limited integration into other academic disciplines. This condition raises both conceptual and practical issues regarding how to design a model of Islamic Religious Education that systematically, applicatively, and contextually integrates scientific knowledge and spirituality within contemporary higher education. This study aims to formulate such an integrative framework through a qualitative approach based on an in-depth literature review of books, journal articles, and research findings, which are analyzed thematically and conceptually. The results identify three main strategies: the development of an interdisciplinary curriculum that internalizes ethical–tawhidic values within professional sciences, the implementation of value-based pedagogy that connects spiritual concepts such as as-sidq and al-amanah with real-life case studies, and the strengthening of campus culture that supports value internalization through co-curricular activities and community service. The synthesis of findings indicates that this integrative model has the potential to enhance students’ moral awareness, spiritual resilience, and ethical decision-making capacity in responding to the dynamics and complexities of modern life. The conclusion emphasizes that the integration of scientific knowledge and spirituality in Islamic Religious Education is not merely a curricular supplement, but a strategic necessity in higher education. The novelty of this study lies in the formulation of a conceptual framework that positions spirituality as an overarching paradigm that provides meaning, direction, and ethical responsibility for the entire structure of knowledge, while offering an applicative model to overcome the dichotomy between secular science and religion in order to produce graduates with strong character, reflective capacity, and a commitment to social responsibility. The theoretical and practical implications of this model are expected to serve as a reference for academic policy development and innovation in Islamic Religious Education learning that is adaptive to global challenges and responsive to the needs of students across contemporary interdisciplinary fields in a sustainable, transformative, and contextually Islamic humanistic value-based manner.
Abstract:This study presents the results of a systematic literature review highlighting the effectiveness of game-based badminton learning approaches as a relevant instructional strategy in physical education. A review of eight selected…
elected articles indicates that the integration of game-oriented activities can enhance students’ fundamental technical skills, tactical understanding, and enthusiasm throughout the learning process. An in-depth analysis of the findings reveals that learning models that position students at the center of activity are able to facilitate more meaningful learning experiences through game situations that closely resemble real on-court conditions. Furthermore, the interaction patterns created through game activities contribute to the development of psychomotor skills and increase students’ readiness to engage confidently in competitive scenarios. Evaluation of various forms of implementation suggests that game-based learning innovations, whether through structured models or application-based media, hold significant potential to improve the quality of badminton instruction. Nevertheless, this review also identifies several challenges, including limited long-term studies, research concentration at specific educational levels, and insufficient exploration of affective and cognitive variables. These findings emphasize the need for further research with broader coverage to gain a deeper understanding of how game-based approaches can be implemented sustainably and deliver optimal benefits for students’ competency development across diverse physical education contexts in Indonesia.

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.

mpetition among driver-partners, which directly affects fluctuations in their income. This study aims to empirically analyze the influence of competition level, working hours duration, and fare policies on the income of GoRide partners in Denpasar City. A quantitative approach was used in this research, with the population consisting of all active GoRide driver-partners in the area. The sample was determined using the Slovin formula with a 10% significance level, resulting in 67 randomly selected respondents. Data were collected through the distribution of structured questionnaires and analyzed using multiple linear regression methods to examine the effect of each independent variable on income as the dependent variable. The results show that the competition variable has a significant negative effect on partner income, indicating that the higher the level of competition, the lower the income earned. Conversely, working hours have a positive and significant effect, indicating that increased working duration directly contributes to higher income. Meanwhile, fare policy shows a positive but insignificant effect, meaning that although there is a statistically positive relationship, the effect is not strong enough to significantly impact income. These findings highlight the importance of efficient management of working hours and strategic adaptation to competition levels as efforts to maintain the economic sustainability of driver-partners. In addition, platform providers are advised to periodically review fare policies to ensure they remain aligned with market dynamics and partner needs, in order to maintain a sustainable income balance.
