This study successfully investigated the engine performance and emission characteristics of a dual injection system that uses both gasoline and ethanol fuels. The study utilized a microcontroller-based control system (PGM-FI) to substitute ethanol fuel injection for gasoline injection. Ethanol fuel was injected at the inlet with three different pressures: 1.0 bar, 1.2 bar, and 1.4 bar, while gasoline injector pressure was fixed at 2 bar. Results showed that substituting ethanol injection with a pressure of 1 bar resulted in a slight decrease in torque and power, but it was the best compared to the other pressures tested. The study found that the use of ethanol injection resulted in improved fuel economy at an ethanol injector pressure of 1 bar with a reduction in SFC of 8.89%. Exhaust emissions were also reduced, with a maximum reduction in CO emissions of 42.54% occurring at a pressure of 1 bar. Similarly, the lowest HC content in exhaust gas was observed at a pressure of 1 bar, which was reduced by 44.48%. However, the results highlighted that ethanol injection pressure could significantly reduce fuel consumption for case A-04 and increase the air-fuel ratio.

Haute couture-making techniques are critical competencies to be mastered by fashion engineering education (CEE) graduates. However, until now, many graduates have been unable to master these techniques optimally. Various studies and field phenomena confirm that they are unprepared for supporting knowledge (SK), socio-cultural, and psychological aspects. This phenomenon prompted us to measure practical learning readiness (PLR) in these three dimensions. In addition, we also examine the differences between dimensions and indicators and test the determination in constructing the PLR to determine the order of solving the problem. The survey was conducted on 386 CEE students with criteria who were currently studying haute couture (HC). The results of the descriptive analysis confirmed that psychological conditions (PC) and SK had a low level, while socio-cultural support had a high level. The results of the comparison test show that the three are generally similar, although there are notes in several indicators. Although all dimensions contribute significantly to constructing PLR, PC contribute the highest. This indicates that low PC are the first step to be addressed by CEE. Furthermore, several notes related to the decrease in knowledge-supporting practice are also the second effort that CEE must make to boost PLR in its students.

The competency of vocational high school students is still said to be lacking in work readiness. This is caused by a lack of encouragement for oneself, family, school facilities, school environment, etc. This research aims to analyze the mediating role of work motivation in determining vocational school students' work readiness. This research uses an ex-post facto quantitative approach with the path analysis method. Research subjects in 3 vocational schools in machining engineering expertise in class XII with a total sample of 193 people. Data collection uses questionnaires, interviews, and documentation. Hypothesis testing in this study used SmartPLS 3 software. The findings show that work competency and industrial work practice experience can influence work motivation. Work motivation can directly influence students' work readiness. Indirectly, work competency affects work motivation through work readiness. Indirectly, industrial work practice experience affects work motivation through work readiness. It was concluded that work motivation plays a role in determining vocational school students' work readiness, especially in class XII machining engineering, followed by work competency and industrial work practice experience. So it is recommended to the vocational school community always to be motivated so that students are ready to work, have sufficient competence and experience, and always pay attention to the 3 things researchers discovered and discussed because vocational schools aim to work, continue, and become self-employed.
