This study aims to analyze the effect of body angle variations on propulsion force, drag coefficient, and freestyle swimming performance using a biomechanical approach. Movement efficiency in swimming plays a crucial role in improving athlete performance. This study employed a quantitative experimental design with university or club-level swimmers with at least three years of training experience as subjects. Subjects were selected through purposive sampling with the criteria of being healthy, familiar with freestyle techniques, and willing to follow the research procedures. The instruments used included 3D motion capture to record body angles and movement coordination, force sensors to measure propulsion force and drag coefficient, and a timekeeping system to calculate average speed. The body angle variations tested were 0°, 15°, and 30°, each with three replications. Data were analyzed using descriptive statistics to describe the mean, standard deviation, and data distribution, and comparative statistics (ANOVA or paired t-test) to compare performance between angle variations. The results showed that a 15° body angle provided optimal performance, with increased average speed and propulsion efficiency compared to 0° and 30° body angles. These findings confirm that body angle regulation plays a crucial role in reducing water resistance and increasing propulsion. The study concluded that a 15° body angle is the ideal position for improving freestyle swimming performance. Further research is recommended to expand the number of subjects, explore variations in other swimming strokes, and integrate physiological data for more comprehensive results.

Bandung Regency, which is experiencing overcapacity in landfills, has implemented a waste management solution involving the separation of organic and inorganic waste. Inorganic waste, which is notoriously difficult to decompose, has prompted the Bandung Regency government to adopt a community-focused approach to waste management, establishing waste banks in school-age communities. However, the project has encountered challenges, as evidenced by the fact that some schools have implemented waste banks but have not been actively engaged in their operations. This has led to the project's suboptimal implementation in Bandung Regency schools.The objective of this study is to identify the challenges associated with the inactivity of waste banks in Bandung Regency schools, as perceived by students and administrators.The study utilises the triple drivers of ecopreneurship, focusing on the economic, social, and environmental benefits of school waste banks. This research employs a mixed methods approach, utilising both quantitative and qualitative data collection methods. The quantitative approach involves the administration of surveys to students, followed by data processing using descriptive statistics. The qualitative method involves conducting interviews with administrators, and the data is processed using the Miles and Huberman model. The findings of the research indicate that the implementation of a waste bank for the management of inorganic waste in a school environment is positively received by the school, despite the presence of obstacles related to waste collection sites, socialisation among students, and differences between administrators and students regarding the most significant focus or choice for implementing waste banks in schools.It is anticipated that the research results will contribute to the understanding of inorganic waste management in waste banks that are less active in the school environment. The study thus recommends further research in schools that are routine or active in waste bank implementation activities, with a view to describing overall information about the implementation of school waste banks, especially in schools in Bandung Regency with school waste bank projects.
