This research focuses on analyzing the impact of fundamental financial ratios on stock prices in the banking sector, specifically examining PT. Bank Mandiri Tbk. The key financial ratios investigated include Return On Assets (ROA), Loan to Deposit Ratio (LDR), Non-Performing Loans (NPL), and the ratio of Operating Expenses to Operating Income (BOPO). The study employs a quantitative descriptive research method, utilizing secondary data sourced from annual reports spanning the period from 2014 to 2023. Multiple linear regression analysis is utilized as the primary analytical tool to address the research questions and hypotheses.

This indicates that these financial ratios are critical indicators for investors and stakeholders when evaluating the performance and market value of banking institutions. The research highlights the importance of these financial metrics in shaping market perceptions and stock valuations, providing valuable insights for investors, financial analysts, and decision-makers in the banking industry. Furthermore, the study contributes to the existing body of knowledge regarding the relationship between financial performance indicators and stock market behavior. By emphasizing the correlation between these ratios and stock prices, the research underscores the necessity for stakeholders to monitor and analyze these key financial metrics to make informed investment decisions. Overall, the results affirm the relevance of fundamental financial ratios in assessing the financial health and competitive positioning of banks, particularly in the context of PT. Bank Mandiri Tbk.

This study aims to examine and analyze the influence of individual characteristics, job characteristics, and competence on employee motivation and performance. A quantitative research method was employed, with data collected through questionnaires distributed to 137 AR and Special AR employees at BPJS Ketenagakerjaan across East Java, selected using the Proportional Random Sampling technique.

The results indicate that individual characteristics, job characteristics, and competence significantly influence motivation. However, individual and job characteristics do not directly affect performance, whereas competence has a significant direct impact on performance. Additionally, motivation does not have a direct effect on performance, but individual characteristics, job characteristics, and competence were found to influence performance through motivation. The study concludes that to enhance employee performance, organizations must consider individual characteristics, job characteristics, and competence while also providing appropriate motivation. Future research is recommended to explore other factors that may affect employee performance in the context of public organizations.
