g logistics costs and increasing demands for delivery timeliness. The research problem focuses on the extent to which shipping cost efficiency and the quality of freight forwarder services can improve export delivery performance in a measurable and sustainable manner. A quantitative approach was applied by collecting survey data from the company’s logistics managers and export managers to capture perceptions and experiences related to the research variables. Data analysis was conducted using structural equation modeling to examine the causal relationships among shipping cost efficiency, freight forwarder quality, and export delivery performance. The results indicate that shipping cost efficiency has a positive and significant effect on export delivery performance through reduced operational costs, improved logistics coordination, and smoother export processes. Freight forwarder quality is also proven to have a positive and significant effect through enhanced service reliability, documentation accuracy, and delivery timeliness. The conclusion confirms that the combination of cost efficiency and logistics service quality constitutes a strategic factor determining the success of corporate export delivery. The novelty of this study lies in integrating the measurement of cost efficiency and freight forwarder quality using a SEM approach applied to the Indonesian palm oil export industry, a context that has received limited empirical attention. This contribution provides empirical evidence for the development of export logistics management and strategic decision-making, enriches the academic logistics literature, and offers practical implications for improving national export competitiveness, formulating corporate policies, and managing long-term logistics partnerships based on measurable performance and efficiency orientation. The findings are expected to serve as a reference for future research and professional practice in agribusiness sectors oriented toward global markets with high logistics risks and intense competition that demand continuous, data-driven managerial innovation grounded in reliable and context-specific empirical evidence for the future of national industries.

among this generation indicates instability in employee retention, which can impact operational efficiency and continuity, particularly in the service sector. This study aims to empirically examine the influence of Non-Physical Work Environment, Compensation, and Workload on Turnover Intention among Generation Z workers in the Coffee Shop industry in Pontianak City, with Job Satisfaction as a mediating variable. A quantitative approach was employed in this study, with data collected through an online questionnaire using a five-point Likert scale. A total of 200 respondents aged 18–27 years were selected using purposive sampling based on relevant criteria. Data were analyzed using Structural Equation Modeling with the Partial Least Squares (SEM-PLS) approach via the SmartPLS 4 software. The analysis results show that the Non-Physical Work Environment has a significant negative effect on Turnover Intention, while Compensation has a negative but not significant effect. Workload has a significant positive effect on Turnover Intention. Furthermore, the Non-Physical Work Environment and Compensation have significant positive effects on Job Satisfaction, while the effect of Workload is not significant. Job Satisfaction is proven to act as a significant mediator in the relationship between the Non-Physical Work Environment and Compensation on Turnover Intention, but it does not mediate the relationship between Workload and Turnover Intention. These findings emphasize the urgency of formulating managerial strategies focused on improving the quality of the work environment and implementing adaptive compensation policies, in order to sustainably reduce turnover rates among Generation Z workers.
Abstract:Anxiety disorders in teenagers are a serious issue that can impact various aspects of their lives, such as social interactions, academic achievement, and emotional well-being. To address these challenges, group counseling…
g has proven to be an effective approach. In group counseling, teenagers can share their experiences with others facing similar issues, creating a supportive and understanding environment. Techniques like open discussions help them identify the causes of their anxiety more effectively, while role-playing allows them to practice new ways of dealing with anxiety-inducing situations. Relaxation exercises also assist them in developing skills to manage anxiety effectively in their daily lives. Literature studies indicate that group counseling not only reduces anxiety levels in teenagers but also enhances their social skills, self-confidence, and emotional resilience. With support from family, schools, and the community, group counseling can become a sustainable strategy in promoting teenagers' mental well-being. Therefore, it is important to consider that there is no one-size-fits-all approach for all teenagers. However, group counseling provides a safe and structured platform for teenagers to learn from each other, strengthen their coping skills, and make progress in overcoming their anxiety. With this approach, it is hoped that teenagers can build a strong foundation for their ongoing mental health.
