ABSTRACT ARTICLE INFO Companies listed on the Indonesia Stock Exchange are required to ensure transparency in their financial statements to gain public trust. In financial statements, audit quality is a critical factor in ensuring this transparency. High quality driven by various supporting factors such as firm size, audit committee, auditor reputation, and leverage. Consequently, this study investigates the impact of firm size, audit committee, auditor reputation, and leverage on audit quality among manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the 2019Ae2023 period. Utilizing a purposive sampling method, the study selected 60 companies based on specific criteria. consistently listed on the IDX, availability of comprehensive data for all independent variables, and no delisting throughout the observation period. This resulted in a total of 300 firm-year observations analyzed by multiple linear regression. The empirical results demonstrate that firm size, audit committee, auditor reputation, and leverage simultaneously exert a significant influence on audit quality. Furthermore, partial analysis reveals that while firm size, audit committee, and auditor reputation significantly affected audit quality, leverage did not have a statistically significant impact.

INTRODUCTION As a key institution in IndonesiaAos financial system, the Indonesia Stock Exchange plays a role in promoting transparency through the publication of companiesAo financial Transparency and accuracy in financial reporting form the foundation for building Therefore, optimal corporate performance is supported by high-quality audits. However, audit failures in detecting irregularities still occur today. For example, in 2022. PT. Indofarma was found to have caused a loss to the state of Rp. 8 billion, which was only uncovered through an investigative audit by the State Audit Agency (BPK), despite having previously received an unqualified opinion. A similar case occurred at Efishery, which manipulated its financial statements to attract investors, even though it had been audited by PwC and Grant Thornton . This phenomenon raises doubts about the effectiveness and credibility of the audit process in Indonesia. Several previous studies have examined various variables that influence audit For instance. Wijaya et al. found that while auditor reputstion and audit committees significantly impact audit quality, audit tenure and rotation do not. Conversely.

Anam et al. revealed that while firm size and audit rotation contribute to audit quality, leverage remains an insignificants factor. Finally. Akbar and Hermi . highlighted a significant relationship between firm size and the integrity of financial statements on audit quality. Firm size is believed to influence audit quality because larger firms tend to have better internal control systems and are subject to closer scrutiny by the public and regulators, thereby promoting higher-quality audits. Large firms have more experienced management and better internal control systems compared to smaller firms or relatively new firms. therefore, large firms produce higher-quality audits than small firms (Wijaya et al. , 2. Audit committees play a crucial role in overseeing the financial reporting process, so their existence and effectiveness can enhance audit quality. (Tahilia et al. , 2. explain that the audit committee is accountable to the board of commissioners and assists the board in overseeing both internal and external audits. Meanwhile, the Indonesian Audit Committee Association (Badan Pengawas Pasar Modal dan Lembaga Keuangan, 2. states that the audit committee is formed by the board of commissioners to oversee the implementation of corporate governance within the company. Auditor reputation is also considered influential because auditors with a strong reputation typically adhere to strict professional standards and strive to maintain their Auditors with experience and a high level of trust are more likely to produce highquality audits at Big 4 firms. This audit quality is not influenced by the auditorAos reputation. This indicates that firms affiliated with Big 4 firms do not always provide high-quality audits (Andriani & Nursiam, 2. Meanwhile, leverage is expected to be associated with audit quality because companies with high debt levels tend to face stricter oversight, compelling auditors to exercise greater diligence. A companyAos leverage describes its ability to pay liabilities using its assets. High leverage reflects the companyAos financial health, prompting creditors to impose stricter requirements (Abigail & Tampubolon, 2. This study aims to bridge the critical research gaps arising from the persistent discrepancy between expected audit quality and actual outcomes, alongside the inconsistent findings in previous literature regarding the determinants of audit integrity. focusing specifically on manufacturing companies listed on Indonesia Stock Exchange (IDX) for the 2019-2023 period, this research addresses a sector that uniquely susceptible to high operational complexity and significant inventory valuation risks, which were further intensified by the global economis volatility of the COVID-19 pandemic. This timeframe is crucial as it captures how financial pressure during and after the crisis influenced audit risk and quality within a sector that serves as the backbone of the Indonesian economy. Through an in depth analysis of firm size, audit committees, auditor reputation and leverage, this study seeks to clarify how these variables interact in a high stakes industrial context, ultimately providing comprehensive insights for auditors, regulators and stakeholders to enhance financial standards in Indonesia. The Effect of Firm Size on Audit Quality Firm size is measured by total assets, revenue, or the number of employees. The larger the firm, the higher the expectations regarding audit quality (Wijaya et al. , 2. Large-scale companies generally have more established internal control systems and are subject to closer scrutiny by the public and regulators. Theoretically, large firms have more resources to facilitate a comprehensive audit process, reducing the likelihood of undetected material errors. Therefore, larger companies are expected to be associated with higher audit quality.

No. 1 / April 2026, p. p-ISSN : 2550-0732 e-ISSN : 2655-8319 The Effect of Audit Committee on Audit Quality Conducted by (Akbar & Hermi, 2. indicates that the presence of an audit committee can improve audit quality. The audit committee acts as a bridge between the external auditor and the board of commissioners. An effective and independent audit committee . easured by the number of members and frequency of meeting. ensures that the financial reporting process is strictly monitored. This oversight encourages auditors to maintain high professional standards, thereby enhancing the overall quality of the audit. H2: The Audit Committee influences audit quality in manufacturing companies listed on the Indonesia Stock Exchange during the 2019Ae2023 period. The Effect of Auditor Reputation on Audit Quality High-reputation audit firms tend to be more independent and professional because they have lower economic dependence on clients (Darwis & Muhammad, 2. Auditors affiliated with the Big Four accounting firms are perceived to possess higher quality standards, superior training, and more robust methodologies compared to smaller firms. They also have a significant incentive to protect their brand reputation from being tarnished by scandals. Consequently, they are more likely to exercise higher professional skepticism and produce more credible audit opinions. H3: Auditor reputation influences audit quality in manufacturing companies listed on the Indonesia Stock Exchange during the 2019Ae2023 period. The Effect of Leverage on Audit Quality According to (Abigail & Tampubolon, 2. , high leverage tends to have a negative impact on audit quality because companies focus more on profitable projects. High debt levels often increase agency risks. Companies with high leverage may face intense pressure from creditors to demonstrate strong financial performance, which might tempt management to engage in "creative accounting. " In response, auditors typically increase their diligence and expand audit procedures to mitigate the risk of fraud, which indirectly impacts the depth and quality of the audit. H4: Leverage influences audit quality in manufacturing companies listed on the Indonesia Stock Exchange during the 2019Ae2023 period. The Effect of Firm Size. Audit Committee. Auditor Reputation, and Leverage on Audit Quality (Firdaus & Sopian, 2. note that larger firms have better internal control (Lailatul & Yanthi, 2. , the frequency of meetings and the size of the audit committee can improve audit quality. (Mauliana & Laksito, 2. , the reputation of the public accounting firm has a positive impact on improving audit quality. Futhermore, (Firdaus & Sopian, 2. , leverage does not have a significant effect on audit quality. Simultaneously, the scale of the company, the effectiveness of internal oversight, the professional credibility of the auditor and the financial risk structure create a collective environment that determines the reliability of financial statements.

METHODS The research method employed was a quantitative approach using purposive sampling, which involved several criteria for selecting the sample, namely. companies listed on the Indonesia Stock Exchange (IDX) during the 2019Ae2023 period, companies with complete data regarding Firm Size. Audit Committee. Auditor Reputation, and Leverage for the 2019Ae2023 period, companies that were not delisted or suspended during the 2019Ae2023 period. The data were obtained from annual reports published on the official website of the Indonesia Stock Exchange for 2019-2023. The study evaluates Firm Size (X. as a reflection of the companyAos overall scale, which is technically captured through the (Ln(Total Asset. Audit Committee (X. variable represents the oversight function responsible for internal controls and measured specifically by the number of committee members. Auditor Reputation (X. variable focuses on the publicAos trust in the auditorAos name and measured using a nominal dummy variable, where a value of 1 is assigned if the firm is affiliated with a Big 4 accounting firm, a value of 0 is assigned if there is no such affiliation. Leverage (X. variable describes the extent to which a companyAos assets are financed through debt and quantified by the Debt to Equity Ratio (DER). Lastly. Audit Quality (Y) as the dependent variabel is measured through the audit fee. To test the research hypotheses, the data are analyzed using Multiple Linear Regression. The regression model is formulated as follows: Y = yu yu1 x1 yu2 x2 yu3 x3 yu4 x4 e This analysis includes conducting classical assumption tests specifically the normality, multicollinearity, heteroscedasticity tests to ensure the model's validity. The study utilizes the t-test for partial hypothesis testing and the F-test to determine the simultaneous effects of the independent variables. Furthermore, the coefficient of determination (R. is assessed to measure the model's overall explanatory power in describing the dynamics and interactions among variables during the study period.

The results of the classical assumption tests demonstrate that the regression model meets all necessary criteria for valid statistical inference. The Kolmogorov-Smirnov normality test yielded a significance value of 0. 074, which is greater than 0. 05 and indicates that the data is normally distributed. Regarding multicollinearity, all independent variables exhibit Variance Inflation Factor (VIF) values below 10 and Tolerance values above 0. confirming that no multicollinearity exists within the model. The Glejser test for heteroscedasticity further shows that the significance values for each variable exceed the 05 threshold, proving that the model is free from heteroscedasticity issues.

No. 1 / April 2026, p. Firm Size Audit Committee Auditor Reputation Leverage Dependent Variable: Audit Quality Source: Data processed . Based on the table above, it can be concluded that: Hypothesis 1 indicates that variable X1 has a significant value of 0. 021 < 0. 05, meaning that the firm size variable (X. has a significant effect on the audit quality variable (Y). This proves that the larger the company, the higher the audit quality. Hypothesis 2 indicates that variable X2 has a significant value of 0. 037 < 0. 05, meaning that the audit committee variable (X. has a significant effect on the audit quality variable (Y). This proves that the consistency in the performance of the number of members on the audit committee can improve audit quality. Hypothesis 3 indicates that variable X3 has a significant value of 0. 039 < 0. 05, meaning the auditor reputation variable (X. has a significant effect on audit quality (Y). This proves that the higher the auditorAos reputation, the greater the improvement in audit quality. Hypothesis 4 indicates that variable X4 has a significant value of 0. 391 > 0. 05, meaning that the leverage variable (X. does not have a significant effect on the audit quality variable (Y). This proves that the amount of a companyAos debt does not influence an improvement in audit quality. The regression model is formulated as follows: Y = 19. 587x4 e Discussion The Effect of Firm Size on Audit Quality Based on the t-test results, the firm size variable was proxied by the Natural Logarithm (L. of Total Assets and yielded a significant value of 0. 021 < 0. This indicates that firm size significantly influences audit quality. This suggest that as a company grows in complexity and scale, the demand for high quality financial reporting increases From an Agency Theory standpoint, larger corporations face higher agency costs due to the wider gap between ownership . and control . (Serly & Zulvia, 2. In such environments, managers may be more inclined to engage in information asymmetry to protect their interests. Consequently, larger firms engage superior audit services as a Aubonding mechanismAy to reduce these cost and provide credible assurance to a vast pool of external investors. These findings corroborate the work of (Mawarini & Triani, 2. and (Anam et al. , 2. , reinforcing the notion that firm size acts as a primary driver for rigorous external monitoring. The Effect of the Audit Committee on Audit Quality Based on the results of the t-test, audit committee was proxied by the number of members, and a significance value of 0. 037 < 0. 05 was obtained, indicating that the audit committee has a significant effect on audit quality. While previous research by Mawarni and Triani . suggested that audit committees are often a mere AuformalityAy, our results align with Wijaya et al. , suggesting that a larger committee allows for better task The depth of this findings lies in the Auresource based viewAy a lager committee provides a broader range of financial expertise and oversight hours, which directly enhances the internal control environment. However, the contradiction in previous literature highlights a The Effect of Firm Size. Audit Committee.

For the audit committee to effectively improve audit quality, it must move beyond legal compliance and actively challenge managementAos accounting estimates and the auditorAos findings. The Effect of Auditor Reputation on Audit Quality Based on the results of the t-test, in which auditor reputation was compared between Big 4 and non-Big 4 public accounting firms using dummy variables 1 and 0, a significant value of 0. 039 < 0. 05 was obtained, indicating that auditor reputation significantly influences audit quality. These results are consistent with a study (Wijaya et al. , 2. showing that auditor reputation plays a crucial role in audit quality. From a behavioral perspective, the Big four accounting firms operate under a different risk reward calculus than smaller firms. This is often referred to as Aureputational capitalAy. Because these firms have spent decades building a global brand, the cost of an audit failure legal fees, loss of clients, and brand erosion, far outweighs the auidt fee of any single This creates a powerfull, self regulating incentive, the Big four are not just service providers, they are gatekeepers of credibility. The Effect of Leverage on Audit Quality Based on the results of the t-test, leverage was proxied by the Debt-to-Equity Ratio (DER), and a significant value of 0. 391 > 0. 05 was obtained, indicating that leverage does not have a significant effect on audit quality. This align with the results of studies by (Mawarini & Triani, 2. and (Anam et al. ,2. , suggesting that the level of a companyAos liabilities does not necessarily dictate the quality of audit. This results implies that in the sampled firms, debt might already be governed by restrictuve covenants or direct monitoring by banks, making the external audit quality less sensitive to changes in leverage. It suggests that auditors do not necessarily perceive high leverage firm as Auhigh riskAy in a way that fundamentally changes the audit outcome, or perhaps that management does not use audit quality as a tool to appease creditors in this specific market context. The Effects of Firm Size. Audit Committee. Auditor Reputation, and Leverage on Audit Quality Based on the results of the F-test, a significance value of 0. 035 < 0. 05 was obtained, proving that firm size (X. , audit committee (X. , auditor reputation (X. , and leverage (X. collectively have a significant effect on audit quality. These results are further supported by a coefficient of determination (RA) of 0. 40, indicating that the independent variables account for 40% of the variation in the dependent variable. Thus, a combination of internal company characteristics and the selection of a reputable external auditor is necessary to achieve high audit quality. The combined model highlights that audit quality is a product of Auchecks and balancesAy. While auditor reputation provides the external technical competence, the audit committee serves as the internal bridge that ensures the auditor has the necessary aaccess and independence to perform effectively. When a large firm is paired with a Big four and functional audit committee, the Aumonitoring densityAy increases. This synergy creates a environment where material misstatements are significantly more likely to b detected and corrected, compared to if these factors acted in isolation. CONCLUSION The research identifies three primary factors that actively enhance the quality of a company's audit. First, firm size plays a crucial role as an organization grows, it typically has more resources and complex structures that contribute to more rigorous audit Similarly, the audit committee serves as a vital internal mechanism for quality The Effect of Firm Size.

No. 1 / April 2026, p. p-ISSN : 2550-0732 e-ISSN : 2655-8319 The presence and activity of this committee are directly linked to better audit Furthermore, auditor reputation specifically whether an auditor is affiliated with a "Big 4" firm remains a strong predictor of high-quality results, in contrast, leverage appears to have no meaningful impact on audit quality in this context. Whether a companyAos debt levels rise or fall, the quality of the audit remains largely unaffected. When viewed collectively, the combination of firm size, audit committee effectiveness, auditor reputation, and leverage has a significant integrated effect on audit Essentially, while leverage alone may not move the needle, the synergy of organizational scale, strong internal oversight, and elite external partnerships creates a robust environment for high-standard auditing. The implications of these findings are multifaceted. For the general public, this research provides a clearer lens through which to view corporate transparency and accountability, enabling more informed decision making. In an academic context, specifically for campus, these results enrich the existing body of accounting literature and support the development of more robust teaching materials. Finally, for practicioners and researchers, this study serves as a practical application of auditing theory, sharpening analytical capabilities and fostering a more critical response to evolving issues in the accounting profession. Based on the research results, the coefficient of determination (RA) is 0. 40, meaning that stakeholders and regulators should prioritize the quality of internal oversight and auditor selection over capital structure when assessing financial credibility. However, this study is limited by its 40% explanatory power, leaving 60% of the influence to other Future research is encouraged to incorporate additional factors such as audit tenure, audit rotation, audit fees, and professional skepticism to provide a more comprehensive understanding of the determinants of audit quality, based on an economic journal source compiled by (Arif & Lastanti, 2. titled the effect of audit tenure, audit rotation, audit fee, and auditor specialization on audit quality with the audit committee as a moderating variable REFERENCES
