Reveal the Key to Profit Change: Analysis of Important Factors in Mining Companies in Indonesia

The Indonesian mining industry has been a significant contributor to the country's economy, with many mining companies listed on the Indonesia Stock Exchange (IDX). However, the industry has faced numerous challenges, including fluctuations in global commodity prices, environmental concerns, and regulatory issues. In this context, understanding the factors that influence the profitability of mining companies is crucial for investors, management, and policymakers. This study aims to reveal a causal relationship between financial ratios and changes in profit in mining companies listed on the IDX.

Background and Literature Review

Financial ratios are widely used by investors, analysts, and management to evaluate a company's financial performance and make informed decisions. Among the various financial ratios, Gross Profit Margin (GPM), Net Profit Margin (NPM), Earning Power of Total Investment (EP), and Return on Equity (ROE) are considered essential in assessing a company's profitability. GPM measures the proportion of gross profit to sales, while NPM measures the proportion of net profit to sales. EP represents the return on total investment, and ROE measures the return on shareholder equity.

Previous studies have investigated the relationship between financial ratios and changes in profit in various industries. However, the specific context of the Indonesian mining industry has not been extensively studied. This study aims to fill this gap by examining the causal relationship between GPM, NPM, EP, and ROE on changes in profit in mining companies listed on the IDX.

Methodology

This study uses a causal approach and is carried out with replication of previous research. The research population includes mining companies listed on the IDX for the period 2006-2011. From a total of 31 companies, researchers took 7 companies as a sample with a purposive sampling method. The data used is secondary data.

The study analyzes the relationship between GPM, NPM, EP, ROE, and changes in profit using the Granger causality test and a fixed effect model. The Granger causality test is used to determine whether GPM, NPM, EP, and ROE have a causal relationship with changes in profit. The fixed effect model is used to estimate the coefficients of the regression equation and to control for individual-specific effects.

Results

The results of this study show a causal relationship between the GPM, NPM, and EP variables to changes in earnings. This means that changes in GPM, NPM, and EP can cause changes in earnings. The simultaneous test shows that the GPM, NPM, EP, and ROE variables together have a significant influence on changes in earnings. Partial tests indicate that the GPM, NPM, and EP variables significantly affect changes in earnings. Meanwhile, the ROE variable does not show a significant effect on changes in earnings.

Additional Analysis and Explanation

The results of this study have several important implications for stakeholders in mining companies, especially investors and company management. The study shows that GPM, NPM, and EP have a significant influence on changes in earnings. This emphasizes the importance of effective financial management strategies to improve operating efficiency, profit margin, and return on investment.

The importance of GPM, NPM, and EP in determining the profit performance of mining companies requires management to actively monitor and manage these ratios. Although ROE does not show a significant effect on changes in earnings, this does not mean that ROE is not important. ROE remains an essential ratio to measure the return on shareholder capital.

Conclusion

This study confirms that GPM, NPM, and EP have a significant influence on changes in profit in mining companies. This emphasizes the importance of effective financial management strategies to improve operating efficiency, profit margin, and return on investment.

Recommendation

  • Mining companies need to adopt strategies that focus on increasing GPM, NPM, and EP to increase profitability.
  • Company management needs to monitor and analyze financial ratios regularly to map the company's financial performance and take appropriate strategic steps.
  • Further research is needed to analyze other factors that might affect changes in profit in mining companies.

Limitations and Future Research Directions

This study has several limitations. Firstly, the sample size is relatively small, and the study only focuses on mining companies listed on the IDX. Secondly, the study only examines the causal relationship between GPM, NPM, EP, and ROE on changes in profit and does not consider other factors that might influence profitability.

Future research directions include analyzing the relationship between financial ratios and changes in profit in other industries, examining the impact of other factors on profitability, and investigating the effectiveness of financial management strategies in improving profitability.

Conclusion

In conclusion, this study provides valuable insights into the causal relationship between financial ratios and changes in profit in mining companies listed on the IDX. The study shows that GPM, NPM, and EP have a significant influence on changes in earnings, while ROE does not show a significant effect. The study's findings have important implications for investors, management, and policymakers, and highlight the need for effective financial management strategies to improve profitability.
