Abstract

The primary goal of education was the development of an individual's potential to foster intellectual, emotional, social, creative, and critical ways of thinking. It was important to remember that the concept and purpose of education can vary across cultures and contexts, and attitudes about education can also change over time as social, technological, and human developments occur. This research aimed to solve problems that arise in the classroom to improve students' creativity and critical thinking. This type of research used classroom action research that focuses on improving classroom learning in a practical manner pursued by a teacher by developing activities that can improve the quality of the learning process in the classroom. The data analysis results of the student product creativity assessment were 75% in the excellent creativity category and 25% at the excellent creativity level. Implementation of PjBL model had an effect on increasing student creativity as evidenced by the results of hypothesis testing, namely by testing with the Gain Score method, which there were N-gain results of 0.53 and showed a moderate increase in creativity compared to student scores before the implementation of the PjBL model, which there was an increase in the value before the model was implemented.

Abstract

This study was triggered by the existing teaching modules for the Shielded Metal Arc Welding (SMAW) subjects taught at vocational high schools, which do not align with the Freedom to Learn-Independent Campus (FLIC) learning objectives, and do not provide a systematic organization. In order to enhance the learning experience, this research developed a new learning module that integrated Problem-based Learning (PBL), promoting critical thinking, and the practical application of theoretical concepts, following the FLIC curriculum. Utilizing a Research and Development (R&D) approach with the Instructional Design Institute (IDI) model, this study involved two welding instructors and four lecturers as validators to assess the content and usability of the module. The IDI model comprised three steps: instructional (define), development (develop), and institute (evaluate). The research findings regarding the validity assessment by subject matter experts yielded a final validity score of 0.924, while media and language experts provided a score of 0.936, meeting the valid criteria. The practical usability test of the learning module resulted in a score of 94%, indicating that it is highly practical for students to use as learning media. Based on the validity and practicality assessments of the developed module, it can be concluded that the SMAW learning module is highly practical to use as teaching media, aligning with FLIC curriculum.

Abstract

Although the Project Based Learning (PjBL) model has been widely introduced in vocational education, studies that specifically analyze its effectiveness in improving student competence in the Basic Mechanical Engineering Design (PDTM) subject at vocational high schools remain limited. This study aimed to analyze the effectiveness of the Project Based Learning model in improving the competence of Grade X students in the Mechanical Engineering expertise program at SMK Negeri 1 Pariaman in the PDTM subject. The research employed a Classroom Action Research design implemented in two cycles, each consisting of planning, implementation, observation, and reflection stages. Through this approach, students were actively engaged in project-based tasks that enabled them to apply theoretical knowledge in practice. The findings showed a significant increase in students’ affective participation, psychomotor skills, and academic achievement. Quantitatively, the proportion of students achieving mastery increased from 40% in the first activity to 88.57% in the subsequent activity, while the average student score rose from 67.48 to 83.6. These results indicate that Project Based Learning is an effective instructional approach for developing students’ critical thinking, innovation, teamwork, and practical competence, thereby better preparing them to meet the demands of the modern industrial sector.

Abstract

This community service program aims to empower rice farmers in Koto Padang Village, Dharmasraya Regency, through the application of appropriate technology in the form of a rice polishing machine (polisher). The main problems faced by farmers were the absence of local polishing facilities and dependence on rice milling units in neighboring villages, which increased transportation costs, processing time, and reduced product quality. The implementation method used a participatory technology approach involving lecturers, students, and the Rawang Bintungan Farmers Group. The activity consisted of several stages: field survey, problem identification, machine design using SolidWorks, fabrication, testing, training, and handover. The machine, driven by a 7 HP motor, has a working capacity of 300–500 kg/hour with 90–95% milling efficiency. Results show that the machine reduced operating costs by up to 30% and increased rice yield quality and polishing efficiency compared to traditional methods. Furthermore, 90% of the trained participants were able to operate and maintain the machine independently. This program demonstrates that collaborative innovation between universities and local communities can strengthen food security and farmer independence through sustainable technology transfer.

Abstract

Squat is a fundamental exercise for improving lower body strength; however, improper execution may increase the risk of musculoskeletal injury. Conventional motion analysis systems, such as marker-based technologies, provide high accuracy but require expensive equipment and controlled environments, while monocular camera-based approaches often suffer from limited three-dimensional representation. Therefore, this study proposes a low-cost squat analysis system, gui_mocap, which integrates monocular computer vision with vector-based mathematical modeling for real-time motion analysis. The system employs pose estimation to detect body landmarks and reconstructs joint kinematics in three-dimensional space using geometric vector operations. Knee joint angles are computed using the dot product formulation, and an Exponential Moving Average (EMA) filter is applied to improve measurement stability. Experimental evaluation was conducted using multiple squat repetitions to analyze motion patterns and consistency. The results demonstrate that the system can accurately identify key movement phases, including standing, deep flexion, and return to standing, while producing smooth and stable joint angle trajectories. Furthermore, the system is capable of analyzing repeated movements and generating descriptive statistics, such as average joint angles and range of motion, indicating consistent performance across repetitions. This study contributes a practical and affordable solution for real-time motion analysis using a monocular webcam, with potential applications in home-based exercise monitoring and basic rehabilitation.

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.
