ity of empirical field data on screw-pile behavior under repeated loading and to evaluate the agreement between theoretical predictions and actual in situ responses. The methodology employs an experimental approach through in situ testing with screw-pile diameters of 10 cm, 15 cm, and 20 cm, and embedment depths ranging from 0.6 m to 1.0 m. The tests were conducted under both static and repeated tensile loading using a hydraulic jack system, accompanied by vertical deformation measurements to establish load–displacement curves. Theoretical capacity was calculated using a limit equilibrium approach for comparison with experimental results. The findings reveal a nonlinear load–displacement response, characterized by initial stiffness followed by progressive deformation into the post-yield stage. At a maximum load of 2.858 tons, deformation increased with diameter, from 5.10 cm (10 cm) to 8.49 cm (20 cm). Under repeated loading, failure occurred at a lower load of approximately 1.6 tons with a maximum deformation of 1.648 cm, indicating potential capacity degradation due to cyclic loading. The comparison between theoretical and field results shows significant deviations, with analytical predictions generally underestimating the in situ capacity. This highlights the limitations of simplified models that do not fully account for shaft adhesion, installation disturbance, soil heterogeneity, pore-water pressure effects, and cyclic degradation. Overall, this study contributes valuable field pull-out test data for screw piles in clay under repeated loading, emphasizing the need for design calibration based on full-scale testing for slope stabilization applications. The results also suggest opportunities for further research involving long-term monitoring and advanced modeling of cyclic degradation.

tionship with fellow human beings and oneself. This research employs a qualitative method with a literature review approach, analyzing sources from the Qur’an, Hadith, and relevant academic studies. The findings indicate that integrating morality toward Allah and the Prophet serves as the fundamental foundation in shaping a strong character, while morality toward parents and oneself reinforces the social and psychological dimensions of a Muslim individual. Consistent application of these moral values contributes to the formation of a harmonious, responsible, and virtuous Muslim personality in daily life. This study offers significant implications for Islamic character education and spiritual development of the Muslim community
Abstract:This study analyzes the competing interests within the Kartu Petani Berjaya (KPB) policy as part of efforts to promote sustainable community-based agricultural development in Lampung Province. The KPB program was launched…
d with the goal of improving farmers' welfare through digitally integrated agricultural services. However, initial observations indicate resistance from some farmers and signs of political interest dominance in both the formulation and implementation processes. The study aims to identify the political motives behind the policy, the sustainability of the program, farmers' literacy regarding the E-KPB system, and the extent to which the program empowers farmers and engages stakeholders. Using a descriptive qualitative approach with thematic analysis and source triangulation techniques, data were collected through in-depth interviews with academics and government officials, as well as document studies. The findings reveal that the dominance of regional leaders in decision-making has led to a program orientation that is more symbolic and electoral in nature. The dynamics of competing interests emerge both vertically and horizontally, resulting in weak coordination and reduced policy effectiveness. The transition from KPB to E-KPB has also shifted the program’s focus and reduced its tangible benefits for farmers. The study recommends strengthening multi-stakeholder collaborative governance in agricultural policy, reevaluating the structure of the E-KPB system, and actively involving academics and farmer associations. These findings contribute theoretically to the study of public policy and policy framing, and practically to improving the implementation of programs based on the real needs of farming communities.

y plays a key role in helping educators and thinkers develop and understand educational theories. This paper, through a literature review, aims to explore the connection between philosophy and educational theory, drawing on various theoretical approaches and findings from prAevious authors. Philosophy influences the development of other fields of knowledge, and this forms the horizontal relationship between philosophy, including philosophy of education, and other branches of knowledge. In a vertical sense, philosophy of education is connected to other fields, such as educational science and the history of education. The results of this study conclude that philosophy's role in educational theory provides a profound contribution to discovering the truth in educational theories, thus making education not only a scientific discipline but also offering practical benefits in its implementation.

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.
