The role of auditor independence, integrity, competence and professionalism in improving audit quality to strengthen government transparency and accountability

2025-12-21T10:04:55+07:00

Transparency and accountability are key principles of good governance, particularly in the management of state finances. Public sector audits play a strategic role in ensuring the reliability of government financial reports and enhancing public trust. However, the paradox of audit quality is still common, where government entities obtain an Unqualified Opinion (WTP) but still face financial irregularities. This situation indicates that audit quality is determined not only by the audit results but also by the characteristics of the auditor. This study aims to examine the role of auditor independence, integrity, competence, and professionalism in improving audit quality and their implications for strengthening government transparency and accountability. The research method used is a literature review by analyzing audit textbooks, national scientific journals, and regulations related to public sector audits descriptively and critically. The study results indicate that auditor independence and integrity are the main foundations in maintaining the objectivity and credibility of audits, while competence and professionalism play a role in ensuring the accuracy of audit procedures and the quality of recommendations. These four factors simultaneously improve audit quality and contribute significantly to strengthening transparency and accountability in government financial management.

Integrating garch, markowitz mean–variance, and lstm for risk, volatility, and portfolio analysis of four major Indonesian banking stocks 2015 – 2024

This study examines the risk structure, volatility behavior, and optimal portfolio construction of four major banking stocks in Indonesia BBCA, BBRI, BMRI, and BBNI during the 2015–2024 period through the integration of the GARCH(1,1) model, Markowitz Mean–Variance optimization, and Long Short-Term Memory (LSTM)-based forecasting. Daily closing price data is transformed into log returns and tested for stationarity before further analysis. The GARCH estimation results indicate persistent high volatility across all stocks (?+? close to 1), with BBNI and BBRI the most responsive to market shocks, while BBCA remains the most stable stock. Markowitz optimization produces a Minimum Variance portfolio dominated by BBCA, while the Maximum Sharpe portfolio allocates funds entirely to BBCA due to its superior return efficiency. The LSTM is able to represent price trends well, as evidenced by low prediction error values for BBRI and BBNI and accuracy between 58–61 percent. The integration provides a comprehensive analytical framework for understanding changing market risk dynamics and supporting adaptive investment decision-making in the Indonesian banking sector. These findings confirm that the hybrid approach can improve risk mapping while maximizing portfolio performance through a combination of historical information, dynamic volatility, and price trend predictions.
