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 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.","PeriodicalId":233393,"journal":{"name":"NOZEL Jurnal Pendidikan Teknik Mesin","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133150961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers make innovations to overcome these problems by making an e-module product as student learning material with concepts and material content that are more interesting and easily understood by students. It is hoped that this e-module can increase students' interest in learning in KBGT lessons (workshop work and technical drawing) at SMKN 8 Malang.

The method used in this research is experimental. This research was conducted on polymer blend composites, namely recycled High Density Polyethylene (rHDPE) and recycled Polypropylene (rPP) with bamboo fiber reinforcement with variations in gamma ray doses of 0 kGy, 25 kGy, 50 kGy, and 75 kGy. Bamboo is processed using a crusher into fibers with a size of 40 mesh and treated with 5% NaOH alkali for 10 minutes then dried using oven for 24 hour at a temperature of 105 °C to remove lignin contained in bamboo fibers. The composite was made using two machines, namely an extrusion machine with a heater temperature of 175 °C, 180 ºC, 185 ºC, and 190 ºC with a screw speed of 25 rpm. Then the injection molding machine with a temperature of 220 ºC with a specimen mold temperature of 90 ºC and an injection pressure of about 45 bar for 20 minutes. Gamma ray treatment was carried out after making the specimen before testing. Where a gamma cell irradiator is used and as a source of gamma rays, cobalt-60 (Co-60) is used. Tensile and water absorption tests are used to determine the physical and mechanical properties of the composite material according to ASTM D638 type V and ASTM D570-98 standards. The test results showed that the higher the dose used, the lower the physical and mechanical properties of the composite. The highest tensile strength was found at the 25 kGy dose treatment of 13.68 MPa and the lowest at the 75 kGy dose treatment. The lowest water content absorption and thickness expansion after 144 hours of immersion were at a 50 kGy gamma dose of 3.43% and 1.27%, respectively.
