Abstract

The aim of this research is to determine the influence of liquidity ratios, profitability, solvency and asset turnover ratios on share prices in energy sector companies on the Indonesia Stock Exchange. The phenomenon that occurred was when the energy sector stock index became the highest compared to other sectors throughout 2022, reaching 36 percent with growth of 2.1 percent. The sampling method for this research uses a purposive sampling method, where of the eighty-four energy sector companies, only thirty-two companies were selected that had complete financial reports for 2021-2022. The results of the research show that the variable factors Current Ratio and Debt to Equity Ratio partially have a negative effect on stock prices, while the variable factors Net Profit Margin and Total Asset Turnover ratios partially have a positive effect on stock prices. Meanwhile, simultaneously the variables Current Ratio, Net Profit Margin, Debt to Equity Ratio and Total Asset Turnover have a significant influence on share prices. It is hoped that future research will be able to determine the effect on stock returns.

Abstract

This study investigates the influence of transformational leadership, job satisfaction, and burnout on turnover intention among Generation Z employees in Indonesian start-up companies. Utilizing a quantitative research approach with 150 respondents from fintech, e-commerce, and logistics start-ups in Jakarta and Bandung, data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that transformational leadership significantly enhances job satisfaction and reduces burnout, but it does not directly affect turnover intention. Burnout significantly increases turnover intention, while job satisfaction does not serve as a significant mediator in the relationship between transformational leadership or burnout and turnover intention. These results highlight burnout as a critical factor driving employee turnover and suggest that leadership strategies alone are insufficient to retain Gen Z talent. The study underscores the importance of addressing emotional well-being, work-life balance, and organizational support systems to mitigate turnover in high-pressure start-up environments.
