Abstract

Critical Thinking Skills (CTS) is a fundamental ability that every student must have. In the modern era of 21st century learning, students are required to have broad understanding, creativity, the ability to solve problems, a nd ways of thinking from various points of view. This research is research on critical thinking skills in Vocational High School students. The instrument used is The Watson-Glaser Critical Thinking Appraisal (WGCTA) where the focus of measurement includes 5 indicators, namely argumentation ability, assumption ability, deduction ability, interpretation ability and conclusion drawing ability. This research uses quantitative methods because the data used are the results of pure test scores. This research was conducted on class 11 students of the Machining Engineering study program at State Vocational Hight School 1 Gombong. Critical thinking skills (CTS) measurement focuses on learning lathe machining techniques. The research results showed that 52.77% of students had very high critical thinking skills (CTS) abilities or classification A. Meanwhile, 2.78% of students had low abilities or classification D. Students' highest abilities are dominated by indicators of drawing conclusions. Meanwhile, the highest average score for classification A is 87.37 and the lowest for classification D is 62. Overall the critical thinking skills of the 5 WGCTA indicators in class 11 students of the machining engineering study program at State Vocational Hight School 1 Gombong have classification A.

Abstract

Indonesia merupakan negara dengan jumlah penduduk yang padat namun minim lapangan pekerjaan meningkatkan tingkat kekhawatiran pada mahasiswa untuk mendapat pekerjaan dan mulai berfikir untuk memulai sebuah usaha (wirausaha). Hal ini terjadi baik pada mahasiswa ekonomi maupun non ekonomi. Penelitian ini bertujuan untuk mengetahui seberapa tinggi minat wirausaha khususnya pada mahasiswa Pendidikan mapunun non kependidikan. 156  mahasiswa Universitas Sebelas Maret Surakarta dengan 70 mahasiswa non kependidikan dan 86 mahasiswa Pendidikan terlibat sebagai responden dari kuesioner yang telah didistribusikan menggunakan Google Form. Dengan hasil menunjukkan bahwa minat wirausaha pada mahasiswa Pendidikan lebih unggul dari mahasiswa non Pendidikan. Hal ini dapat terjadi karena mahasiswa FKIP memiliki keunggulan dalam Public Speaking, berkomunikasi, menganalisis, dan menentukan perlakuan yang tepat terhadap peserta didik yang dapat di aplikasikan juga pada kehidupan social maupun untuk memulai suatu usaha (wirausaha)

Abstract

This research aims to : 1) Investigate the effect of heating fuel through radial finned copper pipe in the upper tank of the radiator exhaust emissions on cars Suzuki APV; 2) Investigate the effect of adding ethanol to the fuel pertalite against exhaust emissions on cars Suzuki APV; 3) Investigate the effect of heating fuel through radial finned copper pipe in the upper tank of the radiator and the addition of ethanol to the fuel pertalite against exhaust emissions on cars Suzuki APV; 4) Analyze the comparison between the results of the fuel mixture pertalite heating and heating fuel ethanol pertamax through two copper pipe to the exhaust emissions of the Suzuki APV. This research use you right experimental method with a comparative descriptive data analysis. The sample used is a Suzuki APV with G15A1D100006 machine number. Data were obtained from a large  measurement exhaust emission levels CO and HC for 20 seconds at idle rotation with variations mix pertalite and ethanol as much as 0%, 5%, 10%, 15%, 20%, 25%, and 30% using the method without heating fuel and the use of heating fuel through a copper pipe finned radial variation fin spacing of 10 mm, 20 mm and 30 mm In the upper radiator tank. Data obtained from the research that is inserted into the table and displayed in a graph, and then analyzed. The results of this study were: 1) heating fuel pertalite in radial finned pipe through the upper radiator tank to the injection cars Suzuki APV can decrease the value of exhaust emissions of CO and HC;2) Addition of ethanol in fuel pertalite with higher levels of 0% to 20% decline in the value of exhaust emissions of CO and HC. Exhaust emissions of CO and HC to increase again in the levels of ethanolblending with levels of 25% and 30%; 3) heating fuel in a radial finned pipe through the upper radiator tank to the injection Suzuki APV car down the value of exhaust emissions of CO and HC. Value exhaust emissions lowest CO occur in the application of finned pipe distance of 10 mm with a mixture of 20% ethanol content of 19% and HC 0.3 by 2 24 to 33 ppm; 4) The value of exhaust emissions of CO and HC in blending ethanol content to 20% lower than the lowest value of the results of exhaust emissions of CO and HC pertamax pure with a value of 0.354% levels of CO and HC at 229.67 Ppm.

Abstract

This study aims to evaluate the effect of feed rate (advance speed) on the wear of Creusabro 4800 saw blades during the cutting of low-carbon steel using a cold saw machine with a constant cutting speed of 107 m/s. The methods employed include literature review, direct field observation, interviews with technicians and operators, and data analysis from operational logbooks over a 40-day period. The results show that increasing the advance speed significantly accelerates tooth wear, reduces the number of cuts that can be performed, and affects the quality of the cut surface. An advance speed of 0.05 m/s produced 1200 cuts with 0.20 mm wear, while at 0.40 m/s, wear increased to 1.00 mm and the number of cuts dropped sharply to 300 units. Observed wear patterns included flank wear, rounding, and chipping, which were aggravated by thermal load and cyclic pressure due to the geometry of materials such as H-beams and C-channels. The optimal advance speed range was found between 0.10–0.20 m/s, where the number of cuts remained high and wear was within acceptable limits. This study recommends implementing a blade replacement logbook system, using active cooling systems, and evaluating the use of TCT blades as an alternative to improve cutting efficiency and tool life in industrial production settings
