Abstract

The urgent environmental issues of the twenty-first century, particularly climate change, have thrust mechanical engineering into a central position in the creation of novel technologies for a future centered on sustainable energy. From energy-efficient mechanical designs to renewable energy systems, sustainable energy technologies provide a wide range of solutions. This bibliometric analysis uses sophisticated tools, such as VOSviewer, to examine a large dataset of academic articles in mechanical engineering that deal with sustainable energy technology. Dominant research themes, significant writers, collaborative networks, and prominent journals are identified by the study. Important discoveries include the notable increase in research output during the previous 20 years, the rise to prominence of notable writers and research teams, the connection between research themes, and the critical importance of particular papers and journals. These revelations help to shape a more sustainable and ecologically conscious energy future by offering a road map for navigating the complex world of sustainable energy in mechanical engineering.

Abstract

This study looks into how novel mechanical engineering solutions for electric bus technology in Jakarta could change the industry, with an emphasis on improving sustainability, efficiency, and performance. Quantitative data was gathered through technical inspections, stakeholder questionnaires, and real-time monitoring. According to the results, buses with regenerative braking systems, lightweight construction, and cutting-edge drivetrain technologies consume 15% less energy. A comparative investigation revealed a 12% boost in overall speed and responsiveness and a 20% improvement in braking efficiency. The environmental benefits were highlighted by the environmental impact evaluations, which showed a notable 25% reduction in particulate matter and emissions. Positive responses to surveys conducted among passengers and bus operators demonstrated the practical viability and user pleasure of these advances. Although they recognized the potential, city officials stressed the need for a thorough and gradual implementation strategy. According to the research, creative mechanical engineering solutions might completely transform Jakarta's urban transportation system and serve as a template for effective and sustainable mobility.

Abstract

This research investigates the positive relationships between environmentally friendly raw materials, environmental awareness, purchasing decisions, and consumer loyalty within the Central Java manufacturing industry. Utilizing a quantitative approach, Structural Equation Modeling (SEM) with Partial Least Squares (PLS) analysis is employed to analyze data collected from 125 respondents. The findings reveal significant positive associations between the use of environmentally friendly raw materials and purchasing decisions, environmental awareness and purchasing decisions, environmental awareness, and consumer loyalty, as well as environmentally friendly raw materials and consumer loyalty. These results emphasize the importance of sustainability initiatives and environmental awareness in driving consumer behavior and fostering loyalty in the manufacturing industry.
