gue and injury. This study addresses the suboptimal implementation of periodization-based microcycle planning, training load monitoring, and recovery strategies within a unified system. The objective of this research is to examine the effectiveness of an integrated training management model in improving athletes’ performance and physiological condition. A quasi-experimental method with a pretest–posttest control group design was employed, involving 40 collegiate athletes over an eight-week period. The results indicate that the experimental group showed significant improvements in countermovement jump by 12.2% and spike reach by 3.1%, accompanied by a reduction in sRPE by 11.5% and an increase in recovery scores by 22.5%, while the control group demonstrated no meaningful changes. These findings suggest that the integration of microcycle planning, internal and external load monitoring, and structured recovery strategies enhances physiological efficiency, neuromuscular adaptation, and the sustainability of athletic performance. The study concludes that the integrated training management model is more effective than conventional approaches as it enables objective and systematic control of training intensity. The novelty of this research lies in the development of an integrated training session management model that combines three key components in an applicable, practical, and context-appropriate manner for collegiate athletes, thereby bridging the gap between sport science theory and coaching practice.
Abstract:Modern volleyball requires complex physical capacities, particularly explosive power and match-specific endurance that are closely associated with the performance of anaerobic and aerobic energy systems. Increasing performance…
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.

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.

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.

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:Indonesia, as an archipelagic country, holds a geographically strategic position while also being vulnerable to various forms of transnational crimes, including the entry of illegal immigrants via maritime routes. Law enforcement…
forcement in maritime areas presents its own challenges due to the need to monitor vast territories, limited facilities and infrastructure, as well as the complex modus operandi employed by illegal immigration offenders. In this context, the Water Police (Pol-Air) serves as the main actor in maintaining maritime security and order, particularly in efforts to prevent the entry of illegal immigrants. This study aims to analyze the strategies and actions undertaken by Pol-Air in performing this function, as well as to evaluate the obstacles faced. The research method used is normative legal research with a qualitative approach, through analysis of existing laws and regulations as well as empirical practices in the field. The results of the study indicate that Pol-Air conducts various preventive measures, such as routine sea patrols in vulnerable areas, the use of maritime surveillance technology, improvement of personnel competencies, and public dissemination of immigration law among coastal communities as a form of participatory prevention. In addition, Pol-Air also engages in cross-sectoral coordination with relevant agencies to strengthen institutional synergy. Nevertheless, the implementation of Pol-Air's duties still faces structural and operational challenges, such as budget limitations, lack of integrated information systems, and weak law enforcement against human smuggling networks. Therefore, a reformulation of policies is needed to support institutional strengthening and sustainable inter-agency collaboration.

asar City. The primary objective of this research is to analyze the effects of organizational culture and work discipline on employee performance, while also examining the mediating role of work motivation. Employing a quantitative approach and path analysis method, the study involved all employees of Bakesbangpol Denpasar using a saturated sampling technique. The findings reveal that organizational culture does not have a significant direct effect on employee performance, whereas work discipline exerts a positive and significant influence. Work motivation emerges as a crucial factor affecting performance, with a path coefficient of β = 0.440 and a significance value of 0.000. Although organizational culture significantly influences work motivation, it does not directly impact performance. In contrast, work discipline does not significantly affect motivation. Notably, work motivation significantly mediates the relationship between organizational culture and employee performance, but not the relationship between work discipline and performance. These findings underscore the pivotal role of work motivation as a mediating variable that enhances the impact of organizational culture on performance improvement. With an R value of 0.695 and an Adjusted R² of 0.683, the model explains 68.3% of the variance in employee performance, with the remaining 31.7% attributed to other factors outside the model. The novelty of this study lies in mapping the structural relationships among organizational culture, work discipline, and motivation as a mediating variable within the context of a local governmental institution an area that has been empirically understudied.

in phonological processing. This study aims to examine the effectiveness of the phonic method in improving the reading skills of slow learners through a structured intervention approach. The central research problem addresses how the phonic method can be appropriately adapted to overcome reading difficulties in children with learning delays. The subject of this study was a fifth-grade elementary school student who exhibited marked delays in recognizing letter sounds, constructing words, and understanding simple sentence structures. A case study approach was employed, involving a six-session individualized intervention designed in gradual stages. Each session focused on developing phonological skills, including phoneme identification, blending sounds into syllables, phoneme segmentation, and the introduction of complex patterns such as digraphs and diphthongs. The results demonstrated significant improvement in the subject’s reading ability, evidenced by increased accuracy in letter-sound recognition, reading simple words, and constructing short sentences. Although minor errors in pronunciation and word structure persisted, the subject’s consistent progress throughout the intervention confirmed the phonic method as an effective and applicable approach to teaching reading to slow learners. In conclusion, the phonic method successfully addressed phonological barriers through strategies tailored to the learner’s cognitive profile. The novelty of this study lies in its implementation of the phonic method as a step-by-step phonological intervention model within the context of inclusive primary education an area that remains underexplored and underutilized in both educational practice and research in Indonesia.
