Abstract

The aim of this research is to evaluate the effectiveness of support in the utilization of mobile learning applications among 38 Physical Education, Sports, and Health Teachers in Lahat Regency. Employing a quantitative descriptive methodology through a survey approach, the research encompasses pre-test and post-test assessments. During the pre-test phase, the results highlight a deficiency in teachers' knowledge regarding mobile learning applications, specifically in comprehending their purpose and operational functionalities. Nonetheless, the post-test outcomes signify a significant enhancement, revealing that the teachers developed awareness and proficiency in utilizing mobile learning applications. They demonstrated an improved understanding of the applications' objectives and acquired the necessary skills for their effective implementation. The transition from the pre-test to the post-test phase signifies the success of the provided assistance in bridging the knowledge gap among the teachers. This implies that the intervention, likely delivered in the form of training or guidance, positively influenced the participants' comprehension and utilization of mobile learning applications. The research findings underscore the critical role of targeted support in augmenting educators' familiarity with technology, ultimately contributing to the seamless integration of mobile learning tools in educational settings. Consequently, this study makes a noteworthy contribution to the ongoing discourse on the significance of mobile applications in pedagogy, particularly within the domain of Physical Education, Sports, and Health.Key words: mobile learning, physical education, era 4.0.

Abstract

This study explores the utilization of photovoltaic solar panels as a source of electrical energy to meet the needs in hard-to-reach areas. Using experimental methods, data were collected during observations from September 13 to September 18, 2024, encompassing measurements of voltage, current, and solar radiation intensity. The results indicate that the highest panel efficiency reached 25.12%, while the lowest was 19.25%, significantly influenced by sunlight intensity and panel temperature. Additionally, the highest convective heat transfer coefficient was recorded for Panel 1 at 96.64 W/m²K, showing a direct relationship with thermal conditions. This research emphasizes the importance of system design and the management of environmental factors to enhance panel efficiency. These findings open opportunities for the development of cooling technologies and more efficient energy conversion in the future.

Abstract

This study evaluates the impact of RON 90 and RON 92 fuels on the performance of a 4-stroke engine with a capacity of 2800 Watts. In the applied methodology, a 2800 Watt two-wheeler vehicle was used to test torque, power, and specific fuel consumption (SFC) at various engine speeds. The results show that RON 92 has better torque at 4000 RPM, while RON 90 exhibits higher torque at speeds approaching 7500 RPM. Power analysis indicates that both fuels produce the same maximum power of 8.7 HP, although it is achieved at different engine speeds. Meanwhile, in terms of SFC, RON 92 is more efficient at lower speeds, but the difference narrows at higher speeds. These findings provide insights into the performance of both types of fuel and their use in engine applications.

Abstract

This study explores the effect of blade count on the performance of low-scale horizontal axis wind turbines (HAWT) with NACA 0012 profiles using Computational Fluid Dynamics (CFD) methods. The results show that the turbine with three blades achieves the highest efficiency, with a power coefficient (Cp) of 0.54 at a Tip-Speed Ratio (TSR) of 7, while the four-blade turbine reaches a Cp of 0.48 at a TSR of 6. The mechanical power produced by the three-blade turbine is 1,040.81 W, 28% higher than that of the four-blade turbine (927.28 W). The progressive distribution of the pitch angle in the three-blade turbine minimizes the risk of stall and flow separation. These findings suggest that fewer blades can reduce flow interference and vortex-induced losses, making it an efficient solution for the wind energy potential in Indonesia. Future research should explore geometric and material variations for further optimization.

Abstract

This study aims to develop technology-based Energy Conversion course teaching materials using the Canva application in the form of valid and practical E-Modules. The background of this study is the limitations of conventional teaching materials that are less interactive and have not utilized technology optimally, which causes low student interest and understanding of the material. The research method used is Research and Development (R&D) with the ADDIE (Analyze, Design, Development, Implementation, Evaluation) development model. The subjects of the study were students of Mechanical Engineering Education, Sriwijaya University, class of 2022. The validation results by material experts and media experts showed that the E-Module developed was in the "Very Valid" category, with an average score of 4.6 and 4.5, respectively. The practicality trial conducted through the One-to-One, Small Group, and Field Test stages also showed that the product is included in the "Very Practical" category, with an average score of 4.25 for the One-to-one trial, 3.83 for the Small Group trial and 4.05 after being tested on all 2022 class Palembang students (Field Test). Thus, the development of this Technology-based E-Module is declared suitable for use as an alternative teaching material that can increase the effectiveness of learning and student understanding in the Energy Conversion course
