The three main factors determining combustion efficiency in Otto engines are optimal compression pressure, effective ignition, and fuel quality. In this study, two critical variables—fuel pump pressure (38, 43, and 48 Psi) and fuel type (RON 90 and RON 92)—were analyzed to understand their impact on specific fuel consumption (SFC). An experimental research method was employed to test the effect of independent variables on dependent variables under controlled conditions. The results indicate that a fuel pump pressure of 43 Psi provides the most stable and efficient fuel consumption performance for both fuel types across the entire engine speed range. A fuel pump pressure of 38 Psi is optimal at medium engine speeds but less efficient at high speeds, whereas a pressure of 48 Psi is most efficient at low to medium speeds but decreases in efficiency at high speeds. Overall, RON 92 fuel shows an efficiency improvement over RON 90, particularly at medium to high engine speeds. The combination of a fuel pump pressure of 43 Psi and the use of RON 92 fuel is recommended to achieve optimal specific fuel consumption, as it provides consistent efficiency across various engine operating conditions.

The issue of plastic waste in Indonesia has reached alarming levels with annual production reaching 64 million tons, the majority of which ends up in the oceans, making Indonesia the second largest contributor to global marine plastic pollution after China. Increasing awareness and reducing daily waste generation are crucial to protecting the environment from the serious impacts of plastic's slow decomposition. This research employed accidental sampling with 20 to 30 respondents to investigate the influence of green marketing and green consumerism on purchasing decisions of environmentally friendly products. Data analysis included data exploration to identify patterns and trends, and Ordinary Least Squares (OLS) regression testing to evaluate the linear relationship between independent variables (green marketing and green consumerism) and the dependent variable (purchase decision). The results of multiple linear regression analysis indicate that the Green Consumerism variable (X2) has a positive regression coefficient of 0.260, although it is not statistically significant (p = 0.148), suggesting that consumer adoption of environmentally friendly behavior marginally contributes to purchasing decisions of environmentally friendly products. However, the low Adjusted R Square (0.031) indicates that the model only explains approximately 3.1% of the variability in purchase decisions. Therefore, companies need to consider other factors such as price and product quality, and integrate more holistic marketing strategies to enhance consumer preference for environmentally friendly products. Further research using more sensitive analytical methods could provide deeper insights to support more effective decision-making in dynamic markets.
