One of the most actively traded and liquid stock groups in the capital market is the LQ45 index, which consistently attracts investor attention due to its strong market capitalization and transaction volume. This study aims to analyze the influence of financial performance and financial management strategies on firm value among companies listed in the LQ45 index on the Indonesia Stock Exchange during the 2018–2022 period. The study population consisted of 73 LQ45-indexed companies, with purposive sampling used to select 23 companies that met the research criteria. This research employed a quantitative approach using path analysis to examine both direct and indirect relationships among variables. The findings indicate that profitability and leverage have a positive and significant effect on firm value. In addition, profitability and leverage also positively influence firm size, indicating that companies with stronger profitability and effective debt management tend to expand their operational scale. However, firm size does not significantly affect firm value and is unable to mediate the relationship between profitability, leverage, and firm value. These results suggest that investors place greater emphasis on profitability and leverage indicators than company size when evaluating firm value in LQ45 companies. Therefore, effective financial performance remains the primary factor in enhancing corporate value and investor confidence.

This study aims to examine the effect of Corporate Social Responsibility (CSR) costs and financial characteristics on tax avoidance practices among publicly listed companies with the largest market capitalization in Indonesia. The study is motivated by Indonesia’s relatively low tax ratio compared to other emerging economies in the ASEAN region, which suggests the persistence of tax avoidance practices, particularly among large corporations. Grounded in legitimacy theory and agency theory, this research empirically investigates the influence of CSR costs, profitability, leverage, liquidity, activity ratio, growth ratio, and operating cash flow on tax avoidance. The research sample consists of 50 companies with the largest market capitalization listed on the Indonesia Stock Exchange over the 2020–2024 period, employing a census sampling method and unbalanced panel data. Secondary data were obtained from annual financial reports and analyzed using panel data regression techniques. Tax avoidance is measured using the Book-Tax Differences (BTD) approach, while model selection is determined through the Chow test, Hausman test, and Lagrange Multiplier test. The results indicate that, simultaneously, all independent variables have a significant effect on tax avoidance. Partially, the activity ratio has a negative effect on tax avoidance, whereas the growth ratio and operating cash flow have a positive effect on tax avoidance. Meanwhile, CSR costs, profitability, leverage, and liquidity do not show a significant effect. These findings suggest that asset utilization efficiency tends to restrain tax avoidance behavior, while corporate growth dynamics and strong operating cash flows encourage more aggressive tax management strategies. This study provides empirical evidence from an emerging market context and offers insights for tax authorities and regulators in designing more effective, risk-based tax supervision policies.

Cryptocurrency has become a rapidly developing digital asset class that attracts widespread investor interest due to its decentralized, anonymous, and highly volatile nature. Such volatility creates uncertainty in market movements, making it important to understand the factors that drive fluctuations in returns. This research aims to examine how fundamental indicators namely price, trading volume, and market capitalization affect return volatility, as well as to determine which cryptocurrency demonstrates the highest market efficiency based on risk assessment. The study uses panel data covering the five largest cryptocurrencies by market capitalization (Bitcoin, Ethereum, Tether, USD Coin, and Binance Coin) over the period 2019–2023. The analytical methods applied include panel data regression to identify the determinants of volatility and Value at Risk (VaR) to measure asset risk and efficiency. The findings show that price and trading volume positively and significantly increase return volatility, whereas market capitalization exerts a negative and significant effect, indicating its stabilizing role. Based on VaR analysis, Binance Coin (BNB) emerges as the asset with the highest market efficiency. The study concludes that fundamental indicators play a crucial role in shaping volatility and that BNB offers relatively better risk performance compared to its peers.

This research aims to analyze the effect of CEO power and board gender diversity on modern slavery disclosure (MSD) among Indonesia’s top 50 publicly listed companies by market capitalization. The research uses a quantitative approach with secondary data collected from annual and sustainability reports during the 2022–2024 period. The results show that CEO power has a negative and significant effect on MSD, indicating that stronger CEO power will reduce disclosure transparency. Furthermore, gender diversity on the board of commissioners also shows a negative and significant relationship with MSD, indicating that female representation in supervisory roles has not yet contributed into greater social accountability within Indonesian firms. Meanwhile, gender diversity on the board of directors shows no significant effect. These results suggest that internal governance factors such as CEO power and limited female influence in top positions still hinder companies from being transparent about social and ethical issues. In conclusion, stronger regulations and independent oversight are needed to improve companies’ transparency regarding modern slavery practices.

This study analyzes the mechanism of money creation in Islamic financial institutions by highlighting its relationship to the principle of prudence and the intermediation function. The research background is based on the growth of Indonesia's sharia capital market which by 2025 will reach a capitalization of IDR 5,060 trillion, but still faces conceptual challenges regarding how money is created according to the principles of maqashid al-shariah. The method used is Systematic Literature Review (SLR) with PRISMA guidance on 38 relevant scientific articles. The results of the study show that money creation in the sharia system only occurs through real asset-based economic activities, in contrast to the conventional system that relies on credit and interest expansion. The intermediation function is carried out through partnerships that prioritize proportional sharing of risk and profit, while the prudential principle ensures that monetary expansion remains under control. In addition, research has found that sharia contracts such as murabahah, mudarabah, and musharakah play a role in encouraging productive money circulation while suppressing speculative activities. This study concludes that the integration between the moral and economic dimensions forms a just, stable, and sustainable Islamic monetary paradigm. These findings make a conceptual contribution to strengthening Islamic financial policy in Indonesia, especially in formulating a monetary regulatory framework that is in line with the principles of distributive justice, transparency, and protection of the stability of the national financial system.

This study analyzes the mechanism of money creation in Islamic financial institutions by examining its relationship with prudential principles and financial intermediation. The research is motivated by the growth of Indonesia’s Islamic capital market, which reached a capitalization of IDR 5,060 trillion in 2025, yet conceptual challenges remain regarding money creation in line with maqashid al-shariah. The study employs a Systematic Literature Review (SLR) using the PRISMA framework, reviewing 38 relevant academic articles. Findings indicate that money creation in Islamic finance occurs only through real-asset-based activities, differing from the conventional system that relies on credit expansion and interest. Intermediation functions are carried out through partnerships emphasizing fair risk and profit sharing, while the prudential principle ensures controlled monetary expansion. The study concludes that the integration of moral and economic dimensions establishes a fair, stable, and sustainable Islamic monetary paradigm and contributes conceptually to strengthening Islamic financial policy in Indonesia.

Indonesia’s Islamic capital market has experienced remarkable growth in recent years, evidenced by the increasing number of investors and the rising market capitalization of Sharia-compliant stocks. This article aims to analyze the performance and management strategies of Sharia stock portfolios by reviewing academic literature published in Indonesia between 2019 and 2024. Utilizing a literature review methodology, the study compares the return and risk characteristics of Sharia stocks with those of conventional stocks. It also evaluates the applicability and effectiveness of classical portfolio theories—namely, the Markowitz Model and the Single Index Model—in managing Sharia-compliant investments. The findings reveal that Sharia stock portfolios often perform competitively and tend to exhibit greater resilience and stability during financial crises. This resilience is attributed in part to the rigorous stock screening mechanisms that comply with Islamic principles, excluding sectors and companies that do not meet Sharia criteria. Additionally, various macroeconomic factors such as inflation, interest rates, exchange rates, and global economic fluctuations are found to impact the performance of Islamic stock portfolios. The article highlights that while Sharia investments align with ethical and religious values, they also offer practical advantages in risk management and diversification. Furthermore, digital technology and fintech innovation are seen as essential tools to enhance transparency, accessibility, and investor engagement in the Islamic capital market. The study concludes that the development of Sharia-compliant stock investments in Indonesia holds promising potential, especially if accompanied by improved financial literacy, inclusive investor education, and stronger technological infrastructure. This paper offers valuable insights for policymakers, market regulators, and investors interested in promoting sustainable and faith-based financial practices within Indonesia’s rapidly evolving capital market ecosystem.

This study aims to analyze the impact of the Russian invasion of Ukraine on February 24, 2022, on the Indonesian capital market, particularly on the stocks listed in the LQ45 index, as well as on exchange rates and cryptocurrency trading volumes.

Cooperatives are business entities based on family principles and aim to improve the welfare of members. Organizational and capital completeness are two important factors that determine the effectiveness of cooperatives in achieving their goals. Organizational completeness refers to the structure and governance of a good cooperative, including the existence of an optimally functioning board, supervisor, and member meeting. This research uses a qualitative method. The results of this study reveal that a complete cooperative organization is the key to success in running a cooperative system. In addition to having complete administrators, supervisors, and member meetings, cooperatives also need to have a strong institutional structure. In addition, in terms of capital, having sufficient sources of funds will enable the cooperative to develop its business, expand its range of services, and have financial resilience in the face of risks that may arise. Thus, the overall comprehensiveness of the cooperative's organization and capital will be instrumental in determining the success of the cooperative system. Both aspects support each other to create an operational environment that is stable, transparent, and able to respond to challenges and opportunities in the market.

This research explores the application of Monte Carlo Simulation in estimating portfolio risk in the Indonesian stock market. The primary objective is to assess the effectiveness of this method in predicting portfolio return distribution and managing risk compared to traditional methods like Value at Risk (VaR). Data from the Indonesia Stock Exchange (IDX) were used to analyze stock returns, focusing on sectors such as telecommunications and property. Monte Carlo Simulation was applied to generate multiple scenarios of stock returns based on historical data and probabilistic distributions. The findings show that Monte Carlo Simulation provides a more comprehensive risk estimation, especially for stocks with high volatility and small market capitalization. Unlike VaR, which assumes a normal distribution, Monte Carlo Simulation accounts for extreme risk events and market uncertainties. The study also highlights the importance of diversification, as portfolios with a mix of high and low volatility stocks demonstrate a more stable risk profile. The results suggest that Monte Carlo Simulation is an effective tool for investors looking to manage risk in dynamic market conditions, providing more accurate and reliable estimations compared to traditional risk assessment methods. This research recommends further exploration of Monte Carlo Simulation in other sectors or with varied data for broader applications in risk management.
