Abstract

Turbines are a key component in hydroelectric power generation, including the Archimedes Screw type, which is specifically designed to operate under low head and low water discharge conditions. This study aims to calculate the rotational speed of the Archimedes Screw turbine under varying water discharge rates, analyze the effect of discharge on turbine rotation, and compute and evaluate the turbine’s efficiency. A quantitative experimental approach was employed, with data obtained through direct testing of a designed Archimedes Screw turbine prototype. Research instruments included measurements of turbine rotational speed and the generated electrical power. Tests were conducted three times at a 45° inclination angle. The results showed that the actual power (Pactual) generated was 11.95 Watts in the first trial, 10.96 Watts in the second, and 12.56 Watts in the third. These findings indicate variations in power output influenced by water discharge and demonstrate the potential of the Archimedes Screw turbine as a micro-hydro energy solution for low-flow water sources. The study concludes that optimizing design and operational parameters is essential for improving the efficiency of such power generation systems.

Abstract

Students’ interest in continuing their studies to higher education is an important aspect of educational planning, particularly at the vocational secondary school level, which is oriented toward work readiness and career development. This study aims to determine the relationship between self-potential and motivation and interest in continuing studies to higher education among Grade XI and XII students of SMKS Semen Padang in the 2025/2026 academic year. This study employed a descriptive quantitative approach with a correlational method. The research population consisted of 141 students, while a sample of 59 students was determined using the proportionate stratified random sampling technique. Data were collected through a Likert-scale questionnaire that had been tested for validity and reliability. The results show that there is a very strong and significant relationship between self-potential and motivation, with a correlation coefficient of 0.913 and a significance value of 0.000 < 0.05. Self-potential also has a very strong and significant relationship with interest in continuing studies to higher education, with a correlation coefficient of 0.893 and a significance value of 0.000 < 0.05. In addition, motivation has a very strong and significant relationship with interest in continuing studies to higher education, with a correlation coefficient of 0.812 and a significance value of 0.000 < 0.05. Simultaneously, self-potential and motivation have a very strong and significant relationship with interest in continuing studies to higher education, with a multiple correlation coefficient (R) of 0.894 and a coefficient of determination (R²) of 0.798. These findings indicate that 79.8% of interest in continuing studies can be explained by self-potential and motivation, while the remaining 20.2% is influenced by other factors outside this study. The conclusion of the study emphasizes that self-potential and motivation are internal factors that strongly contribute to students’ interest in continuing their studies to higher education. The implications of this study emphasize the important roles of schools, teachers, and families in developing students’ self-potential and increasing their motivation so that further education planning can be more optimal.

Abstract

This research evaluates the application' of the Project' Based Learning' (PjBL)' learning model in Creative Products and Entrepreneurship subjects in class' XI Heavy' Equipment Engineering' at SMK Negeri 1 Timpeh. SMK Negeri 1 Timpeh strives to achieve the vision of the Revitalization of SMK PK, which emphasizes the preparation of graduates for the world of work or entrepreneurship. Interview results show' that student' learning outcomes' have not reached' graduation standards, and teacher-centred learning conditions and a lack of variety in learning models are the main challenges. Therefore, this research applies the PjBL model as an effort to overcome this problem. The PjBL model is considered the right solution because it emphasizes time-bound processes, focus on problems, and the formation of meaningful learning units. This research includes the results of previous research that shows the success of PjBL in improving student learning outcomes in various educational contexts. This research used method Classroom Action Research (PTK) with an instrument in the form of a project assessment rubric. The research results show a big improve in student learning outcomes after implementing PjBL. In the second cycle, classical completion reached 100%, exceeding the research success indicator. The PjBL model provides alternative options for teachers in learning approaches, creates fun learning experiences, and increases student engagement. It is hoped that the implementation of PjBL can activate students, increase creativity, and produce graduates with skills relevant' to' the demands' of the 21st' century.' This research supports the implementation of PjBL to improve student' learning' outcomes' in Creative Products' and Entrepreneurship' subjects.
