Abstract

This research aims to analyze the influence of the virtual learning environment and participant motivation on their understanding of the New Model Training material at the Astra Motor Training Center Semarang. After the global Covid-19 pandemic occurred, many training and education shifted to virtual learning methods. However, challenges such as lack of face-to-face interaction and potential distractions in the home or work environment can affect participant motivation. This research method is quantitative using surveys of training participants. The results of the analysis show that the virtual learning environment, especially through the Zoom application, has a positive influence on participants' understanding of the training material. Apart from that, participants' motivation also had a significant positive correlation with their understanding. The combination of an effective virtual learning environment and high levels of motivation provides a significant positive impact on understanding the training material. Based on the results of the t test, the following data was obtained: the virtual learning environment variable obtained a significant value of 0.037, which is smaller than 0.05. So these results show the influence of the virtual learning environment on the understanding of New Model Training participants at the Astra Motor Training Center Semarang and the learning motivation variable obtained a significant value of 0.002, which is smaller than 0.05. So these results show the influence of learning motivation on the understanding of New Model Training participants at AMTC Semarang. In conclusion, in the context of the New Model Training at AMTC Semarang, the virtual learning environment has a presentation of 3.8% and participant motivation has a presentation of 9.3% are important factors that are interrelated in increasing participants' understanding of the New Model Training material.

Abstract

Low carbon steel such as ST 37 is widely used in manufacturing and construction industries due to its ease of fabrication and cost-effectiveness. However, one of its main drawbacks is its relatively low hardness and wear resistance, especially after welding processes. The Shielded Metal Arc Welding (SMAW) method is highly influenced by the type of electrode used, which significantly affects the mechanical properties of the weld joint. This study aims to investigate the effect of electrode variation (E6010, E6013, and E7018) on the mechanical properties of ST 37 low carbon steel after undergoing thermochemical treatment using the pack carburizing method. An experimental quantitative approach was used in this research. ST 37 steel samples were welded using three different types of electrodes, followed by pack carburizing at 950°C for two hours using coconut shell charcoal as the carbon source, and then quenched in oil. Mechanical properties were evaluated through tensile and hardness tests, including calculations of strain and elastic modulus. The results showed that the E6010 electrode provided the best performance, with the highest average tensile strength of 25.835 MPa and the highest strain value of 0.2667, indicating strong and ductile weld joints. In contrast, the E7018 electrode yielded the highest elastic modulus at 104.363 MPa, reflecting a stiffer but less ductile material. These findings confirm that electrode selection plays a critical role in determining the mechanical behavior of welds, particularly when combined with surface hardening treatments like pack carburizing. This study contributes to scientific understanding and offers practical recommendations for improving weld quality in both industrial and academic contexts.

Abstract

Background of the problem The development of 21st century competencies requires someone to master various skills, including technology, information and communication skills. So it is an obligation for a teacher to provide distance learning or better known by the abbreviation PJJ. This shows that PJJ plays an important role not only in the development of 21st century competencies but also during the pandemic after COVID-19. However, from the information obtained, all students at Purwodadi National Development Vocational School have smartphones that are used in distance learning. The objectives of this research are: (1) to determine the effect of distance learning on work readiness, (2) to determine the effect of 21st century competencies on work readiness, (3) to determine the effect of distance learning and 21st century competencies on work readiness. The type of research used is quantitative research with a descriptive approach that is ex post facto in nature. Data collection techniques using documentation and questionnaires. The population and sample were 126 and 96 students. The data testing used is a validity test and a reliability test. Test data analysis requirements using normality test, linearity test, autocorrelation test, multicollinearity test, and heteroscedasticity test. Meanwhile, data hypothesis testing uses simple regression tests, multiple regression tests, T tests, F tests, R square tests (determinants) using the help of the SPSS data processing program version 24.0. The results of the analysis show (1) Distance learning on work readiness in the strongly agree category. (2) 21st century competency towards work readiness in the strongly agree category. (3) There is an influence of distance learning and 21st century competencies on work readiness. Which is proven by the results of the F test which shows a significance value (Sig) = 0.000 < 0.05 and the calculated F value = 131.046 > t table 1.41.

Abstract

This study aims to measure the impact of LPG on the performance of a 100 cc 4-stroke motorcycle running on pertalite, including torque, engine power, exhaust emissions, and fuel consumption. This quantitative research uses the true experiment method with descriptive analysis to systematically present the test results. The study shows that the torque produced by LPG is 6.49 Nm at 5000 RPM, which is lower than the torque produced by pertalite, which is 7.27 Nm at the same RPM. The engine power generated by LPG is also lower at 5.06 Hp at 7000 RPM, while the engine power on pertalite is higher at 6.13 Hp at the same RPM. In terms of exhaust emissions, LPG is proven to be more environmentally friendly compared to pertalite. LPG exhaust emissions are lower in all components, such as CO, O2, CO2, HC, Lambda, and AFR. Furthermore, LPG is more efficient in fuel consumption, with efficiency reaching 27.99% to 49.98% better than pertalite. Overall, pertalite is superior in terms of torque and engine power, while LPG is better in terms of exhaust emissions and fuel consumption efficiency.
