Abstract

This study is designed to explore the extent to which product quality, price, and testimonials influence consumer purchasing decisions for electric bicycles in the city of Surabaya. The growing awareness of environmentally friendly transportation has driven the expansion of the electric bicycle market in urban areas. A quantitative approach was employed through a survey method, with data collected using closed-ended questionnaires distributed to 100 electric bicycle consumers. The independent variables in this research include product quality (X1), price (X2), and testimonials (X3), while the dependent variable is purchasing decision (Y). The results of multiple linear regression analysis reveal that, collectively, the three independent variables significantly influence consumer purchasing decisions (F = 153.218; p < 0.001). However, when examined individually, only testimonials showed a statistically significant effect (p < 0.001), while product quality and price did not exhibit a meaningful influence (p > 0.05). The coefficient of determination (R²) was found to be 0.827, indicating that the model explains 82.7% of the variation in purchasing decisions. The findings highlight testimonials as the most dominant factor (β = 0.679), suggesting that businesses should adopt digital testimonial-based marketing strategies to strengthen consumer trust.

Abstract

Pink-collar workers frequently engage directly with customers possessing diverse personalities and demands, requiring strong psychological resilience and interpersonal skills. This study aims to examine the effect of work environment on job satisfaction through the mediating role of self-efficacy among pink-collar workers in Surabaya. A quantitative approach was employed using a survey method involving 100 respondents, selected based on their direct involvement in customer service within the hospitality, education, banking, and retail sectors. Data analysis was conducted using SmartPLS 3.0. The results reveal that the work environment has a positive and significant effect on self-efficacy, indicating that a safe, comfortable, and supportive workplace enhances employees’ confidence in their abilities. Furthermore, self-efficacy significantly influences job satisfaction and partially mediates the relationship between work environment and job satisfaction. The direct effect of work environment on job satisfaction is also significant, affirming that job satisfaction is more likely to occur when the work environment supports employees physically, socially, and psychologically. The research model explains more than seventy-five percent of the variance in job satisfaction, highlighting the importance of integrating both external and internal factors in shaping positive work experiences. These findings provide practical implications for organizations to foster conducive work environments that enhance self-efficacy and job satisfaction among pink-collar employees.
