ABSTRACT This study aims to analyze the effect of sustainability accounting practices and IFRS S1 adoption on firm value, as well as the moderating role of corporate governance and green transition in manufacturing companies in Indonesia. The study used panel data from 21 companies listed on the Indonesia Stock Exchange for the 2021Ae2024 period, using multiple regression methods and model selection using the Chow Test and Lagrange Multiplier, which indicated that the Common Effect model was the best model. The results showed that sustainability accounting practices and IFRS S1 adoption had a positive and significant effect on firm value. In addition, corporate governance strengthened the influence of IFRS S1 on firm value, while the green transition significantly increased the influence of sustainability accounting practices on value creation. These findings emphasize the importance of integrating global sustainability standards, strong governance mechanisms, and a commitment to the green transition in increasing firm value in the manufacturing sector.

INTRODUCTION The corporate world's perspective has changed with the increasing complexity of environmental issues and public awareness of sustainability. Companies now must demonstrate concern for social and environmental issues beyond maximizing economic profits. The green economy initially emerged as a development approach that promotes economic growth, environmental sustainability, and social wellbeing. In this context, sustainability accounting is used as a reporting tool to convey information about a company's social and environmental impacts in a more transparent and measurable manner. Sustainability accounting encompasses both financial and non-financial aspects, enabling companies to report their sustainability performance through global standard reports such as the Global Reporting Initiative (GRI) and the Environmental. Social, and Governance (ESG) framework. Implementing sustainability reporting can enhance a company's reputation and increase investor and stakeholder This makes sustainability accounting part of a company's strategy that not only meets compliance needs but also provides competitive value. During the 2021 United Nations Framework Convention on Climate Change (UNF. , the International Federation of Accountants (IFAC) announced the establishment of the International Sustainability Standards Board (ISSB). The ISSB's primary objective is to develop high-quality, globally recognized corporate sustainability disclosure criteria, while taking into account the demands of capital markets and the expectations of G20 leaders and the International Organization of Securities Commissions (IOSCO). Consequently, the ISSB's new standards will significantly impact the expansion of business activities within companies, as well as the preparation and presentation of financial statements that assist consumers in making informed decisions (Gaviria et al. , 2. On June 26, 2023, the Proceeding Accounting Research Festival | 302 International Sustainability Standards Board (ISSB) announced two sustainability standards: IFRS S1 General Requirements for Disclosure of Sustainability-Related Financial Information and IFRS S2 Climate-Related Disclosures. IFRS S1 is a global standard that requires companies to disclose information on corporate governance, strategy, risk management, and sustainability metrics/targets. Meanwhile. IFRS S2 is a climaterelated disclosure complement to IFRS S1. IFRS S1 is applicable for annual reporting periods beginning on or after 1 January 2024, with earlier application permitted if IFRS S2 is also applied. Meanwhile, corporate governance is a crucial tool for directing and controlling a company's operations in line with strategic objectives and regulatory compliance. Good governance fosters transparency, accountability, and stakeholder trust, all of which directly contribute to increased business value. Empirical research shows that the quality of corporate governance has a significant impact on firm value, with characteristics such as ownership structure, board independence, and audit quality playing a critical role in driving long-term value development (Nathania & Karnawati, 2. Furthermore, the green transition is the process of transforming organizations and industries toward environmentally friendly practices through the use of green technologies, sustainable innovation, and resource efficiency. Given climate change and global environmental demands, this shift is increasingly important. Studies have shown that a company's commitment to green innovation and sound environmental cost management can enhance business value by improving corporate image, investor confidence, and market competitiveness. Corporate governance is crucial for a successful green transition because it enables rational decisionmaking, internal controls, and transparent and accurate sustainability reporting. This enhances a company's position in the rapidly evolving green economy, both in terms of risks and opportunities. Companies with good governance can maximize their green initiatives to deliver significant benefits to shareholders and other Strengthening governance and accelerating the green transition is crucial, especially in Indonesia's manufacturing sector, a key driver of the country's economy. This industry faces regulatory and market pressure to improve environmental performance, which positively impacts corporate value and long-term Sustainability has become a major focus for global and national corporations in recent years, with increasing attention to environmental, social, and governance (ESG) implications. The concept of sustainability is not only crucial for environmental preservation and improving social welfare but also directly linked to a company's long-term performance. Therefore, accurate, transparent, and consistent disclosure of sustainability data is a critical requirement in modern corporate governance. In Indonesia, particularly in the industrial sector, the implementation of IFRS S1 presents both challenges and opportunities. The industrial sector plays a crucial role in the national economy and has a significant impact on the environment, making sustainability disclosure Indonesia has begun its transition to a green sector with a net-zero emissions target by 2050, encouraging industrial companies to adopt environmentally friendly and sustainable business practices according to the Ministry of Industry, 2024. However, the use of IFRS S1 in sustainable accounting reporting requires strong corporate governance to ensure accurate, transparent, and accountable disclosure. Good governance facilitates the integration of sustainability strategies and risk management to create long-term organizational value. On the other hand, the green transition, as a process of business transformation toward environmental sustainability, can act as a moderator, strengthening the relationship between IFRS S1 adoption and corporate value creation . Research on the implementation of IFRS S1 as a global sustainability reporting standard is still in its infancy, particularly in developing countries like Indonesia. To date, most available research focuses on GRI- or ESG-based sustainability disclosures, resulting in limited empirical information on the direct impact of IFRS S1 adoption on business value. This limitation arises because IFRS S1 will only be implemented in 2024, so the academic literature examining its implications is not yet mature enough. Therefore, studies that provide baseline data on how IFRS S1 adoption affects market perceptions and corporate value performance are urgently needed. Another research gap lies in the inconsistency in measuring sustainability accounting procedures. Prior to IFRS S1, studies used a variety of indicators, including the GRI, researcher-created disclosure indices, and third-party ESG ratings. This makes it difficult to compare research results. To date, only a few studies have developed structured disclosure indices based on IFRS S1 components, highlighting the need for a more relevant measurement methodology linked to current standards. In addition to methodological gaps, there are also contextual gaps. Most research on sustainability reporting focuses on various sectors as a whole, even though the manufacturing sector has unique environmental characteristics and sustainability risks. The absence of studies specifically focusing on Indonesian manufacturing companies limits our understanding of how this sector responds to the implementation of IFRS S1. Given the energy- and raw material-intensive nature of the manufacturing sector, sectoral analysis is crucial to determine the impact of new sustainability requirements. This study is significant because it provides empirical evidence in the Indonesian context, particularly in the manufacturing sector, on how the implementation of IFRS S1 can be optimized by leveraging corporate governance and the green transition to create corporate value that is not only financially profitable but also Proceeding Accounting Research Festival | 7 13 environmentally and socially sustainable. This is important for regulators, industry players, and other stakeholders as they support the transition to a green economy and global reporting standards. Legitimacy Theory This theory was first introduced by Dowling and Pfeffer . According to legitimacy theory, companies must align their actions with societal values and norms to gain public support. When business procedures are not aligned with social expectations, legitimacy gaps arise, which can damage the company's reputation and sustainability. To maintain legitimacy in the eyes of stakeholders, companies must ensure that their operational policies and actions are consistent with social and environmental boundaries accepted by . In the context of sustainability reporting, this approach forms the basis for companies to disclose ESG. GRI, and IFRS S1 information to maintain public credibility. Transparent and high-quality disclosures can mitigate reputational risk, increase investor confidence, and enhance company value. Good corporate governance ensures accountable reporting, and a commitment to the green transition adds credibility by demonstrating the company's commitment to addressing current environmental challenges. Theory Institusional Institutional theory suggests that organizations' adoption of IFRS S1 is influenced by institutional factors, namely coercive pressure, norms, and imitation. Regulations and international standard-setting bodies exert coercive pressure on companies to improve sustainability transparency. Conversely, normative and mimetic pressures arise from stakeholder expectations and evolving best practices in the corporate environment. Consequently. IFRS S1 implementation is seen not only as a means of fulfilling legal obligations but also as a strategy to gain credibility in the market and society. Institutional theory views corporate governance as an internal process that ensures compliance with sustainability requirements. Strong governance enhances a company's responsiveness to institutional pressures, making sustainability disclosures more credible. Furthermore, the green transition creates additional institutional pressures, strengthening the positive impact of IFRS S1 adoption and governance on firm value. Companies committed to environmentally friendly business practices are more responsive to sustainability demands, enabling them to leverage IFRS S1 adoption more effectively to enhance their legitimacy and overall firm value. RESEARCH METHOD This study uses a quantitative approach with a causal associative design to examine the relationship between variables. The population in this study is all manufacturing sector companies listed on the Indonesia Stock Exchange (IDX) during the observation period. The sampling technique used is purposive sampling, where sample selection is based on specific predetermined criteria to ensure the sample's suitability to the research object. Secondary data will be collected from annual reports and company sustainability reports. The causal relationship between IFRS S1 Adoption. Sustainability Accounting Practices, and Firm Value will be tested using multiple regression analysis with Moderated Regression Analysis (MRA). This MRA technique is used to test the moderating role of Corporate Governance and Green Transition by including interaction variables in the regression model. Data analysis will be performed using E-Views statistical software, by first conducting a classical assumption test to ensure the regression results are the Best Linear Unbiased Estimator (BLUE). This study conducted data processing using a combination of Microsoft Excel and EViews software to ensure accuracy, efficiency, and validity. Raw data, obtained from secondary sources such as national databases or field surveys, were first imported and cleaned using Microsoft Excel (Microsoft Corporation, 2.

RESULTS AND DISCUSSION Panel Regression Model Selection Chow Test The Chow test was used to determine whether the appropriate panel regression model was the Fixed Effect Model or the Common Effect Model. Based on the estimation results, the p-value for the Cross-section F was 0. 3400 and the p-value for the Cross-section Chi-square was 0. Both values were greater than the 0. 05 significance level, thus concluding that the Fixed Effect Model was not suitable for Therefore, the most appropriate model for this study was the Common Effect Model (CEM). These findings indicate that differences in characteristics between firms in the sample do not significantly impact the structure of the regression model, thus the model without individual effects (CEM) is considered more stable and efficient. This finding aligns with guidelines (Moon, 2. that state that CEM should be used when there are no significant structural differences between observation units. Proceeding Accounting Research Festival | 7 13 Figure 2. Chow Test Effects Test Cross-section F Cross-section Chi-square Statistics Prob. Source: Eviews Output, 2025 The results of the Chow test in this study indicate that the resulting p-values , both in the Crosection F and Cross-section Chi-square , are above the 0. 05 significance level. This condition indicates that the Fixed Effect model does not provide a significant improvement compared to the Common Effect In other words, there is no strong enough difference in behavior between companies in the sample, so that it is necessary to provide a different slope or intercept for each company. The results of the Chow test show that the p-values of the Cross-section F . and Cross-section Chi-square . are greater than 0. This means that the Fixed Effect model is not necessary because there are no significant differences between companies in the sample. Thus, the appropriate model to use is the Common Effect Model, because the pattern of relationships between variables is considered uniform across companies. This model is also more efficient and stable, in accordance with the rules for selecting a panel regression model. In the context of research related to sustainability accounting. IFRS S1 adoption, governance, and the green transition, the Chow Test findings confirm that market reactions and reporting structures of manufacturing companies in Indonesia are relatively similar, making a model without individual effects more appropriate. The common effects model also provides stable and efficient estimates for analyzing the influence of key variables in the study. Theoretically, these results align with the view of Gujarati & Porter . , who explain that the fixed effects model is only appropriate when there are significant differences between observation units. If these differences are not statistically detectable, the common effects model is more appropriate due to its simplicity, unbiased nature, and smaller estimation variance. Lagrange Multiplier Test The Lagrange Multiplier (LM) test is used as a follow-up step after the Chow test to determine whether the most appropriate panel regression model is the Common Effects Model or the Random Effects Model. This test aims to examine the presence or absence of random effects in the panel data, thereby determining whether variations between companies and over time are significant enough to be included in the model as random effects.

Gourieroux, et al. Sumber: Output Eviews, 2025 The Lagrange Multiplier (LM) test results show that the p-values for all three testsAi cross-section . , time . , and both . Aiare all greater than 0. This indicates that the Random Effect model is insignificant and not superior to the Common Effect model. Therefore, there are no random effects between companies or over time that influence the panel data structure in this study. Based on these results, it can be concluded that the Common Effect Model is the most appropriate model to use because the data variation is not strong enough to form a random component. This decision also aligns with the results of the previous Chow Test, which also directed the selection of the Common Effect Results of Testing the Influence Between Variables The estimation results of the Common Effect model show that X1 has a positive and significant effect on Y, indicated by a positive coefficient and a p-value <0. This means that an increase in X1 will increase the value of Y. Thus, the hypothesis that X1 has a positive effect on Y is accepted. Therefore, the IFRS S1 variable has a significant effect on Company Value. Variable X2 also shows a positive and significant influence on Y, as indicated by a p-value less than This means that the higher X2, the higher the Y value. The hypothesis that X2 has a positive influence on Y is accepted. This means that Sustainability Accounting Practices have a significant influence on Company Value. The results of the interaction between X1 and Z1 (X1*Z. show a positive coefficient value with a pvalue <0. This indicates that Z1 successfully strengthens the influence of X1 on Y. Thus. Z1 functions as a significant moderator, so the hypothesis is accepted. Where Corporate Governance strengthens the relationship between IFRS S1 and Company Value. The results of the study indicate that Z2 significantly strengthens the influence of IFRS S1 adoption on firm value. The interaction coefficient X2*Z2 is positive and significant . < 0. This means that the stronger a company's commitment to the green transition, the stronger the impact of IFRS S1 adoption on increasing company value. The green transition encourages companies to improve their energy structure, reduce emissions, and increase operational efficiency, making IFRS S1-based reporting more meaningful to investors. Simultaneously, the results of the regression analysis indicate that variations in firm value (Y) can be significantly explained by the combination of variables X1. X2. Z1, and Z2. The common effect model produces adequate goodness of fit , where all variables collectively contribute positively to increasing firm These results support institutional theory, which states that sustainability, governance, and international regulation (IFRS S. are important pillars for companies to improve legitimacy and market CONCLUSION The results of this study indicate that sustainability accounting practices and the adoption of IFRS S1 play a significant role in increasing the value of manufacturing companies in Indonesia. The implementation of sustainability accounting has been shown to positively contribute by providing more transparent information on environmental, social, and governance performance, thereby increasing investor confidence. Similarly, the adoption of IFRS S1 results in better quality and globally standardized sustainability reporting, thereby strengthening company credibility with stakeholders. This study also found that corporate governance serves as a factor that strengthens the effectiveness of IFRS S1 implementation. Companies with good governance are able to manage the sustainability Proceeding Accounting Research Festival | 7 13 reporting process more accountably, thus increasing its impact on company value. Furthermore, a company's commitment to the green transition has been shown to strengthen the influence of sustainability accounting practices on company value. Company efforts to adopt environmentally friendly technologies, energy efficiency, and emission reductions provide significant added value for both shareholders and the public. Overall, this study concludes that integrating sustainability accounting practices. IFRS S1 implementation, corporate governance, and green transition commitments is an effective strategy for creating higher corporate value. These findings underscore the importance of implementing global sustainability standards and responsible environmental practices to support the long-term competitiveness and sustainability of manufacturing companies in Indonesia.
