The rapid development and population growth in Bekasi Regency, Indonesia, have resulted in increasing traffic density and a corresponding rise in road traffic accidents (RTA), particularly along the critical 28 km Kalimalang Inspection Highway, locally known as "Jalur Tengkorak." This study aims to analyze the simultaneous and partial influence of Vehicle Factors (X1), Human Factors (X2), and Road Physical Condition Factors (X3) on RTA (Y). A quantitative descriptive approach utilizing Multiple Linear Regression (MLR) was employed, based on primary data collected through questionnaires from 100 motorcycle riders and secondary data from Polresta Bekasi (2022). The findings confirm that all three variables significantly and positively influence RTA, resulting in the model \hat{Y} = 2.218 + 0.302 X1 + 0.161 X2 + 0.289 X3 + \mu. The adjusted coefficient of determination (R^2) is 0.514, indicating that 51.4\% of RTA variation is explained by these factors. Crucially, the Road Physical Condition Factor (X3) emerged as the strongest predictor (t=4.429, \beta=0.385), surpassing the traditional dominance of human error. This key finding suggests that mitigation strategies must prioritize urgent infrastructure repair addressing potholes, road waves, and insufficient markings to significantly reduce accident frequency in this corridor.

This study aims to examine and analyze the influence of work stress and work environment on employee performance at PT Yamaha Motor Electronics Indonesia. The research involved 50 respondents selected using a purposive sampling technique, targeting employees who have worked for at least one year. Data collection methods included questionnaires, observation, and literature study. The data were analyzed using data quality tests (validity and reliability), classical assumption tests, multiple linear regression analysis, hypothesis testing (t-test and F-test), and the coefficient of determination (R²), all processed with the assistance of SPSS version 25.The results showed that, based on the partial t-test, the work stress variable had a negative and significant effect on employee performance with a t value of -7.862 > t table 2.011, while the work environment variable had a positive and significant effect with a t value of 5.543 > t table 2.011. Simultaneously, both variables significantly affected employee performance, as indicated by an F value of 43.229 > F table 3.20 and a significance value of 0.000. The Adjusted R Square value of 0.633 indicates that 63.3% of the variation in employee performance can be explained by work stress and work environment.
