Abstract

The speed of the times in terms of technology and people's behavior patterns makes people around the world interconnected. This makes the competition for jobs in society increase. Everyone who wants to survive the competition for a job must have the ability and skills. In this case, the world of education is also influential, where education is not only to seek knowledge but to find or improve skills that are useful for competing for a job. In technological advances, especially in the automotive sector, the world of education, especially vocational education, must always follow the development of technology in the industry. The PTM Study Program should have a curriculum that is in line with the work or competencies in the industry so that ptm study program graduates can compete in the world of work. This study aims to find out whether the curriculum of the PTM FKIP UNS study program has aligned with the competencies needed by the industrial world. This research is a qualitative descriptive research. The source of this research data is documents from industry and the Mechanical Engineering Education Study Program. Purpose sampling data retrieval technique. Data collection was carried out with documentation and finalized with FGD (Focus Group Discussion). There are three data collection points, namely Toyota Nasmoco Ringroad, Daihatsu Adi Sucipto, and Suzuki Pabelan. The source of data from the draft work documents in the industry is the RPS matkul in the automotive field of the PTM Study Program, vehicle inspection sheets, FGD minutes, and periodic service books for gasoline engines and diesel engines. The validity test technique used is data triangulation. Data analysis using content analysis techniques (Analysis content).

Abstract

Technology 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 learning

Abstract

In the current era, automatic motorbikes are the most popular motorbikes and are most widely used for everyday purposes. The motorcycle population always increases by around 5 million units every year. Of this amount, around 70% are motorbikes of the matic type, aka scooters. One trick that is usually used by automatic motorbike lovers to upgrade the characteristics of their automatic motorbike is to replace a part called the CVT roller. The aims of this study were: (1) To find out the effect on fuel consumption produced by a 110cc automatic motorcycle using variations in roller weight. (2) Knowing the effect on fuel consumption produced by 110cc automatic motorbikes using variations of engine speed. (3) Knowing the effect of using roller weight variations at RPM variations on fuel consumption on 110cc automatic motorcycles. The research method used is experimental. The research data was obtained by measuring the Honda BeAT New 2018 motorcycle sample. The independent variable is roller weight Variation and Variation of engine rotation. The dependent variable is fuel consumption. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) The use of variations roller weight 10, 12, and 14 grams have an effect on fuel consumption. The use of a roller that is heavier or lighter than standard (12 grams) has the effect of producing a more different fuel consumption. (2) Variations in engine speed (3500, 5000 and 6500 RPM) have an influence on fuel consumption. Each increase in engine speed, the fuel consumption will also increase. This happens because the higher the engine speed, the higher the amount of fuel burned in the combustion chamber. (3) Has the effect of fuel consumption on the use of roller weight variations and variations of engine speed. This effect lies in the average fuel consumption using less standard rollers when compared to using lighter or heavier rollers. Overall, if you take the best, then the right choice is a standard 12 grams roller, because it has the lowest average fuel consumption value.

Abstract

The development of this fast era makes competition to get a job to increase and become more difficult. In the current competition in the industrial world, it demands an increase in the quality of Human Resources through education. Vocational High School Education also prepares its graduates to go directly into the world of industry, but there are still limitations between the need for human resources in industry and the human resources produced by educational institutions. So therefore Curriculum development in Vocational High Schools is developed by prioritizing the needs of society, one of which is the need to be able to compete directly in industry. The aims of this research are: (1) To find out the alignment process between the SMK curriculum and industry. (2) Knowing how far the curriculum in SMK is aligned with the world of work in industry. (3) Knowing whether the SMK curriculum with industry is feasible.  The method used in the automotive concentration curriculum alignment activities at SMKs uses a qualitative approach with descriptive research. Data collection techniques using techniquespupose sampling. Data collection techniques in this study used data collection techniques in the form of interviews, documents, and observations. The research documents include the Merdeka Curriculum, K13 Curriculum, service books, vehicle inspection sheets, and the results of the FGD minutes. Data analysis techniques in this study used content analysis techniques (analysis content). The research locations were limited to 2 SMK, namely: SMKN 2 Surakarta and SMK Warga Surakarta and three industries, namely: Toyota Nasmoco Ringroad, Daihatsu Adi Sucipto, and Suzuki Pabelan (PT. Solo Indonesia Utama). The data obtained is then juxtaposed between the curriculum and competencies in the industry in tabular form so that it can be seen which curriculum and competencies are not aligned. The results of this study are: The curriculum between automotive engineering vocational schools and industrial competencies is aligned, this is evidenced by the existenceforum grub discussion (FGD) between the SMK and the automotive industry.
