Analisis Ketidakjujuran Akademik Pada Mahasiswa Calon Guru Kejuruan Bidang Teknik Mesin
No full textAcademic dishonesty is considered as one of the disgraceful behaviors that damage the character of students. Considering the important role of teachers in preventing fraud in the learning process, teacher candidate education programs are expected to have a conducive environment to uphold academic integrity. mechanical engineering vocational. This research is a quantitative descriptive study conducted in one of the educational staff educators at a public university in Central Java. Data collection techniques using a survey instrument with a total of 117 students as respondents. The validity and reliability of the data using the help of a statistical data processing software. The results showed that the indications of academic dishonesty of vocational engineering students were 92.3% had been involved in collaborating when doing assignments, 91.5% had been involved in collaborating during exams, 85.5% had been involved in copying and pasting assignments, as much as 98.3%. Never been involved in not reporting cheating in class, opening cell phones for browsing during exams, and fake attendance. The causes of academic dishonesty of vocational engineering students are not ready to face exams, exam questions and heavy assignments, lack of firmness of supervisors, the majority of students do it, the absence of strict rules and punishments. The solution to overcome the academic dishonesty of vocational engineering students is a warning when violating, confirming the supervisor, making the majority of students stop cheating, confirming rules and punishments, making the classroom situation impossible for cheating, ensuring student readiness for exams, prohibiting carrying cell phones when exam and spaced out seats during the exam. The results of this study are expected to be used for efforts to handle and prevent academic dishonesty in teacher education in general
PENGARUH MEDIA PENDINGIN PADA PENGELASAN BAJA S45C MENGGUNAKAN METODE PENGELASAN GAS METAL ARC WELDING TERHADAP KEKERASAN DAN STRUKTUR MIKRO
Get PDFThis study aims to determine the effect of cooling media on microstructure and hardness values on alloy steel S45C using the welding method of Gas metal arc welding (GMAW). This research is using an experimental method. The data analysis technique used is descriptive comparative. The tool used for microstructure testing is Olympus Metallurgical Microscope and hardness test using the Vickers Hardness Tester. Based on the results of the study, it can be concluded that the results of the microstructure show an increase in the structure of pearlite after welding. In raw material, ferrite structures are seen evenly but in the welding results, GMAW which has cooled by using water, air, and oil cooling media show that ferrite is reduced in each specimen, so the pearlite structure dominates. The values of hardness and microstructure in the welding results using water, oil and aircooling media show differences in the level of hardness and microstructure. Specimens with water cooling media at the Heat Affected Zone (HAZ) test point have a higher hardness level of 315.4 VHN when compared to specimens using an oil cooling medium of 268.7 VHN and air conditioning media of 177.4 VHN. Specimens with water cooling media the microstructure in the Heat Affected Zone (HAZ) section showed more pearlite which was evenly distributed compared to specimens using other cooling media, or it could be concluded that the further away from the Las area and HAZ the smaller the pearlite content. This study shows that welding using variations in cooling media changes the microstructure and influences the hardness value of the S45C steel allo

PENGARUH VARIASI UKURAN DIAMETER LUBANG MAGIC RING PADA EXHAUST MANIFOLD TERHADAP TORSI DAN DAYA SEPEDA MOTOR YAMAHA VEGA RR
Get PDFVehicle performance will decrease with increasing age of use, it can be seen from the weakening initial torque and the power of the vehicle when driving unlike the initial production. Magic ring a tool produced by CV. SUMI INOTECH which utilizes the overlapping process of valves. The magic ring mounted on the header exhaust manifold serves to restore exhaust gas that is wasted from the overlapping process to return to the combustion chamber so as to produce more power to push the piston and the performance of the vehicle will increase. This study used an experimental method with the research object of Yamaha Vega RR in 2014. The magic ring used was the 16 mm magic ring serial number (ASJS032125) and the same magic ring but the inner diameter was enlarged to 18 mm. Using descriptive quantitative data analysis, it was found that the use of the magic ring added torque from the standard condition of 7.42% in the use of the 16 mm magic ring and increased by 7.12% in the use of the 18 mm magic ring. The power of the vehicle increased only 0.24% when using the magic ring 16 mm, and the use of the magic ring 18 mm power remained the same as the standard condition

Pengaruh Variasi Bahan Pengikat Terhadap Kekuatan Cetakan Pasir, Permeabilitas, Fluiditas, Kekerasan Logam dan Kualitas Hasil Pengecoran Logam Paduan Al-Si Dengan Metode Gravity Casting
Get PDFThis research was conducted to investigate the effect of binder variation including bentonit, lapindo mud, and portland cement on the silica molding sand strength, permeability, fluidity, metal hardness and the quality of Al-Si alloy casting by using gravity casting method. The experimental design was used on this research and analyzed by using descriptive data analysis. The result showed molding sand containing 15% lapindo mud binder had the highest wet compressive strength (8,73 N/cm2). The molding sand containing 15% portland cement binder had the highest dry compressive strength (>32 N/cm2). The highest wet tensile strength was resulted by the molding sand containing 15% bentonit binder (3,33 N/cm2), while the highest dry tensile strength was resulted by the molding sand containing 15% portland cement binder (18,60 N/cm2). The highest wet shear strength was resulted by the molding sand containing 15% portland cement binder (0,57 N/cm2), while the highest dry shear strength was resulted by the molding sand containing 15% portland cement binder (1,03 N/cm2). The molding sand containing 15% bentonit binder had the finest permeability (210 mm/minute). In the real practical application, the molding sand containing 15% portland cement binder was unable to result an appropriate molding strength when manually compressed in cope and drag (casting flask), thus it was unable to use as metal pouring media. The molding sand containing 15% lapindo mud binder had the finest fluidity but it had the lowest hardness (120,30 HV). The molding sand containing 15% bentonit binder resulted the best Al-Si alloy casting quality and the highest hardness (129,60 HV)
