PENGEMBANGAN E-MODUL PRAKTIKUM KELISTRIKAN OTOMOTIF BERBASIS SELF DIRECTED LEARNING PADA PROGRAM STUDI PENDIDIKAN TEKNIK MESIN UNS
Full text linkTechnology has created numerous benefits in various aspects of life, including education. Teachers and students should integrate technology into their learning plans to ensure effective teaching and learning. The use of technology in education can inspire students to pursue new interests and motivate them to engage in learning activities that enhance their perspectives. The role of an instructor in a student's education is crucial. Self-directed learning (SDL) is an instructional process that requires students to identify their own learning needs, provide resources, and practice learning techniques. By using the right methods and situations in teaching, students can develop their own skills and enhance their learning experience. This study aims to improve the effectiveness of e-module practical on the otomotif kelistrikan in the Mesin Technical Education program.The study on the development of an e-module for otomological pedagogy found that the validity of the e-module met good results with validity scores of 84.4% (very feasible) for material, 85% (very feasible) for media, 75% (feasible) for language, and 83,3% very (feasible) for data from student responses. Critics and respondents also deemed that improvements are needed for the e-module. The results were based on feedback from the committee of otomologists who provided some suggestions about the electronic pedagogical pedagogy module in terms of quality and safety, indicating that improvements are still needed for this module. The e-module will be distributed through the Mesin Technical Education Program at the University of Surakarta.Keywords: development, e-modules, self directed learnin

Therefore, appropriate learning tools are needed in the learning process for CAD 2 courses. Testing the feasibility of these learning tools involves 3 parties, namely material experts, media experts, and users. From the assessment of material experts, it was obtained that the percentage of eligibility averaged 81,75% and was included in the "very feasible" category. From the assessment of media experts, it was obtained that the average percentage of eligibility was 90,55% and was included in the "very feasible" category. The trial process was attended by PTM students who were taking CAD 2 courses. From the user response data of 70 respondents, it was obtained that the average eligibility percentage was 91,24% and was included in the "very feasible" category. The conclusion is that the results of the reconstruction of the Computer Aided Design 1 course are very feasible and suitable for use in the learning process

PENGARUH PENGGUNAAN VARIASI BERAT ROLLER TERHADAP PERFORMA SEPEDA MOTOR MATIC HONDA STLYO 160
Full text linkThis study aims to analyze the effect of roller weight variations on the performance of the Honda Stylo 160 automatic motorcycle in 2024. The research method used is a quantitative experiment with roller weight variations of 13, 15, 17, 19, and 20 grams. Tests were carried out using a dynamometer to measure torque and power. The results showed that the roller weight variation had a significant effect on the torque and power produced. The roller weighing 13 grams produced the highest torque of 23.55 N.m and power of 13.6 HP, while the heaviest roller of 20 grams produced the highest average power of 13.06 HP. The results of this study can be concluded that the use of lighter weight rollers tends to increase torque, while heavier weight rollers tend to increase the power generated. Although there is a general increase in power with an increase in roller weight, variations in the measurement results indicate that other factors such as engine efficiency also play an important role in motorcycle performance
ANALISIS RISIKO DAN PENGENDALIAN BAHAYA BENGKEL PEMESINAN DI SMKS PANCASILA SURAKARTA
Full text linkThis research aims to carry out an in-depth analysis regarding risks and work safety control efforts at the SMKS Pancasila Surakarta Machining Workshop, by applying the Job Safety Analysis (JSA) method. In the direct observation process, a number of potential risks have been identified, including aspects of lighting that are less than optimal, equipment storage management that is not yet fully efficient, conditions of supporting facilities that need to be improved, and a lack of awareness regarding Occupational Safety and Health (K3). This risk analysis then paves the way for the development of control measures that focus on improving lighting, better equipment storage arrangements, strategic placement of supporting facilities, installation of stabilizers on machines, and expanding K3 awareness through industrial work culture. It is hoped that these recommendations can make a significant contribution in creating a learning environment that is not only safe and comfortable, but also more productive for students and teaching staff in vocational school machining workshops. Thus, this research not only illustrates an in-depth understanding of risks in SMK machining workshops, but also offers concrete solutions to improve overall work safety conditions
