This study aims to examine the effect of Thin Capitalization, Sales Growth, and Capital Intensity on Tax Avoidance, with Institutional Ownership as a moderating variable in coal sub-sector companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The background of this study is based on the importance of tax management as a company efficiency strategy, while maintaining compliance with tax regulations. The coal industry was chosen because of its capital-intensive characteristics, fluctuating sales growth rates, and the tendency of companies to engage in aggressive tax planning. The research method uses a quantitative approach with a purposive sampling technique, resulting in 50 company samples during the observation period. Data were analyzed using multiple linear regression with the help of E-Views 13 software to test the direct relationship between variables, and Moderated Regression Analysis (MRA) to test the role of Institutional Ownership as a moderating variable. The results show that Thin Capitalization has no significant effect on Tax Avoidance, which indicates that high debt ratios are not always utilized by companies to reduce tax burdens. Capital Intensity also had no significant effect on Tax Avoidance, indicating that the size of fixed asset investments does not directly influence tax avoidance practices. Conversely, Sales Growth had a significant positive effect on Tax Avoidance, indicating that high sales growth tends to encourage companies to optimize tax-saving strategies. Furthermore, the results of the moderation test revealed that Institutional Ownership did not moderate the relationship between Thin Capitalization, Sales Growth, or Capital Intensity on Tax Avoidance. This finding suggests that the supervisory role of institutional shareholders is ineffective in limiting or influencing tax avoidance strategies in coal companies. This research provides implications for regulators and investors to consider non-financial factors and governance mechanisms in efforts to control tax avoidance practices in strategic sectors like coal.

The war between India and Pakistan has had a devastating impact on the economies of both the countries directly involved and those indirectly affected. The economic impacts of this armed conflict include significant infrastructure damage, reduced production capacity, soaring inflation, rising unemployment, and reduced investment flows. This geopolitical instability has also fueled uncertainty in global financial markets, triggering a "flight to safety" phenomenon, a shift in capital and investment to countries or instruments perceived as safer, such as US government bonds or gold. For Indonesia, this situation has the potential to significantly disrupt national economic stability. One impact is a reduction in foreign direct investment (FDI) inflows, as investors tend to hold back or relocate their investments to more geopolitically stable countries. Furthermore, pressure on the rupiah exchange rate could increase due to global financial market volatility and a decline in international investor confidence. The conflict could also hamper Indonesia's export traffic, particularly to countries with close trade ties with India and Pakistan. Furthermore, these tensions could disrupt global supply chains, particularly for energy and food commodities, many of which pass through strategic trade routes. If the conflict drags on, the price of crude oil and other raw materials could potentially rise sharply, which in turn would increase domestic production costs. This would have a direct impact on inflation and public purchasing power. This situation further complicates the management of Indonesia's monetary and fiscal policies, which currently face significant challenges, such as the imminent maturities of large government debt and a still-widening state budget deficit. The government must take strategic steps to maintain domestic economic stability, strengthen foreign exchange reserves, and encourage export market diversification to reduce over-reliance on conflict-prone countries.

This study aims to analyze the contribution of the life insurance sector to economic growth and financial system stability in Indonesia during the period from 2013 to 2022. Using a quantitative approach and linear regression method, the study finds a positive and statistically significant relationship between life insurance premiums and real Gross Domestic Product (GDP) growth. Additionally, the life insurance sector acts as a long-term funding provider that supports financial market stability through investments in financial instruments such as government bonds. These findings indicate that the life insurance industry not only offers financial protection for individuals but also serves as a key pillar of economic development and financial system resilience. The study recommends enhancing insurance inclusion, financial literacy, and strengthening regulation and corporate governance in life insurance companies to fully leverage their potential contribution to Indonesia’s economy

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.

Extension workers have been instrumental in encouraging farmers to adopt new technologies, aiming to improve productivity, income, social status, and climate resilience. This study investigates challenges in technology adoption and its impact on vegetable production, economic and social enhancement, and climate resilience in Svay Rieng province. Data from 302 agricultural cooperative members were analyzed using Pearson’s correlation to examine relationships and linear regression to predict factors influencing farmers' achievements. Results show that internal challenges (labor, capital, technical know-how) significantly influence success, followed by external challenges. Investments in hard technologies (e.g., net houses, drip irrigation) strongly correlated with achievements, while soft technologies (technical knowledge) had a lesser impact. Regression analysis identified internal challenges and adoption of hard technologies as key predictors, explaining 25% of overall performance, including 36%, 29%, and 25% of economic, social, and climate resilience improvements, respectively. For production, only internal challenges and hard technologies were determinants, predicting 30%. Addressing internal challenges and enhancing technology applications are critical to improving vegetable producers' success in the province.

This study aims to analyze the effects of domestic investments, inflasi, and pengeluaran on Sumatra Utara's income between 2001 and 2020. This study uses the Error Correction Model (ECM) analysis method to determine the impact of independent variables on dependent variables in the pendek data and the Regression Linear Berganda analysis to determine the impact of independent variables on dependent variables in the panjang data. According to the results of the ECM analysis, the variable pengeluaran in the panjang has a significant and positive impact on the sumatera utara's income, while the variable PMDN in the panjang has a positive but not significant effect, and inflasi has a negative and not significant effect. Conversely, the pendek jangka indicates that the pengeluaran variable also has a significant and positive impact on the Sumatera Utara's income, whereas the PMDN and Inflasi variables do not have a significant impact.

This research aims to understand the concept and regulations of Islamic pension funds (dana pensiun syariah) in Indonesia, which impact life in old age based on the Maqasid al-Shariah (objectives of Islamic law). An Islamic pension fund is a pension fund that administers a retirement program based on Sharia principles (DSN-MUI Fatwa Number: 88/DSN-MUI/XI/2013). The management of Islamic pension funds in Indonesia is carried out through investments in Sharia-compliant pension funds that are distributed to participants. This is closely tied to the contractual consequences of the underlying agreement governing the transactional relationship between DPLK (Financial Institution Pension Fund) participants and the Sharia DPLK, which is based on the contract of Wakalah bil Ujrah (agency with fee).This study uses a qualitative approach with a descriptive-analytical method to analyze instruments of old-age protection based on Maqasid al-Shariah in the management of pension funds within Islamic financial institutions. The research is rooted in the management of pension funds aligned with the Maqasid al-Shariah, which represent the main objectives of Islamic law—namely, to realize the welfare (maslahah) of humanity in both this world and the hereafter. This pension fund also serves as a form of old-age security designed to provide income certainty for workers after entering retirement.

Corruption in Indonesia has evolved into a complex phenomenon, often involving money laundering and financial statement manipulation as mechanisms to conceal illicit assets within seemingly legal financial systems. This study focuses on the bribery case involving the Regent of Kepulauan Meranti as the research object, aiming to trace the flow of funds, financial manipulation techniques, and the involvement of both individual and corporate actors. The objective of this research is to analyze the interconnection between corruption, money laundering, and financial statement fraud, and to examine the legal implications of the criminal charges applied within Indonesia’s penal system. This study adopts a qualitative approach using a case study method, with primary data drawn from official documents issued by the Corruption Eradication Commission (KPK) and secondary data from credible media sources. The findings reveal that the corruption scheme was systematically carried out by disguising illegal funds through property investments and business entities. The study also highlights the insufficient application of cumulative charges and emphasizes the need for regulatory enhancement, particularly concerning illicit enrichment provisions. This research underscores the urgency of reforming supervision systems, penal structures, and strengthening the role of forensic accounting in detecting and preventing organized financial crimes in the public sector.

These findings highlight the importance of operational efficiency for the profitability and competitiveness of insurance companies, as well as the relevance of technology adoption in enhancing efficiency. Practical and theoretical implications are discussed.

Inclusive and sustainable economic growth is a major challenge in today's digital age. Financial technology (FinTech) plays an important role in bridging the financial access gap while supporting environmental responsibility through the application of green finance. This study aims to analyse the role of FinTech in promoting inclusive economic growth and environmental sustainability, particularly through the application of blockchain technology in urban renewable energy systems. The research method uses a qualitative approach with secondary data analysis, supported by mathematical models to measure green financial inclusion and FinTech investment efficiency. The results show that the implementation of green FinTech significantly increases financial inclusion, expands economic access for the MSME sector, and reduces carbon emissions through investments in environmentally friendly energy projects. Global case studies in India and Sweden show that multisectoral collaboration and adaptive regulatory policies are key to creating a sustainable FinTech ecosystem. Therefore, the integration of technology, policy, and digital literacy among the public is necessary to realise digital finance that is fair, efficient, and oriented towards a green future

The method employed was an interactive seminar that combined presentations with open discussions. The results showed a significant increase in participants’ understanding of the characteristics of illegal investments, the importance of personal financial management, and the need for caution in making financial decisions. The synergy between academic institutions and the community is expected to serve as a strategic effort to strengthen financial resilience and reduce the number of victims of investment fraud.

There is a large correlation between its economic development and a country’s capital market. The capital market connects individuals with potential investments and helps businesses obtain the necessary financing. The way investors view a company’s growth potential is reflected in its stock valuation. Stock price fluctuations are influenced by several factors, including effective Good Corporate Governance (GCG), capital structure, and financial performance. By examining the impact of GCG, financial performance, and capital structure, this study aims to provide clearer guidelines on how companies in the financial sector of the IDX can influence stock prices from 2020 to 2024. The quantitative method used is multiple linear regression analysis. The study found that stock values ​​were significantly influenced by these three factors, both separately and when combined. These three variables explain a quarter of the variance in stock prices (measured by the Adjusted R² value of 0.256), while the remaining variation is due to variables outside this study. Whether you are an investor or a business leader, these findings can help you make better financial and governance choices and will pave the way for further research.

This study reviews the comparison between two popular methods in capital budgeting analysis, namely Internal Rate of Return (IRR) and Payback Period (PP), applied in the investment decision-making process at PT Pertamina (Persero). As a state-owned company in the energy sector that runs various important projects, Pertamina needs to evaluate investment feasibility efficiently. IRR is used to assess the effectiveness of long-term investments by taking into account all cash flows as well as the time value of money, while PP emphasizes more on how quickly the initial capital can be returned. This article uses a literature study method with a descriptive-qualitative approach to explore the advantages and disadvantages of each method. The results of the discussion show that IRR provides a more precise picture of long-term investment returns, while PP is useful for identifying projects that quickly return capital. Nonetheless, the use of each method alone is not comprehensive enough. Therefore, it is recommended that Pertamina integrate IRR and PP with other approaches such as Net Present Value (NPV) and sensitivity analysis to support more comprehensive and strategic investment decisions.

This study uses a qualitative method and aims to dissect the differences between Islamic economics and conventional economics. This study found that Islamic economics is based on Islamic principles reflected in the Qur’an and Hadith, emphasizing social justice, balance, and avoiding elements of usury, gharar, and maysir in every economic activity. Meanwhile, conventional economics is based on the principles of a market economy that aims to maximize material profits without considering spiritual or moral aspects. The source of conventional economic law comes from rules made by humans, while Islamic economics refers to the law of Allah. The Islamic financial system uses profit- sharing mechanisms and halal investments, while the conventional system relies on interest as the main source of income. In addition, Islamic economics integrates social instruments such as zakat, infaq, and sedekah for wealth redistribution, while conventional economics emphasizes taxes and government policies. Thus, this study confirms that the fundamental differences between the two systems lie in their philosophical foundations, objectives, and operational mechanisms.  

This study discusses the comparison of green economic policies implemented between Indonesia and Malaysia in supporting inclusive sustainable national development, which is examined normatively through a comparative study approach. Indonesia, through Law No. 30 of 2007 on Energy, Law No. 21 of 2014 on Geothermal Energy, and other regulations, has established a national green program encompassing environmental quality improvement, disaster resilience and climate change mitigation, low-carbon development, and renewable energy development as pillars of national development. Meanwhile, Malaysia's National Energy Policy 2022-2040 and other regulations stipulate that a green economy can be achieved through economic development, the utilization of sustainable energy resources, and environmental quality. Research findings indicate that Indonesia has not maximized the implementation of a green economy due to the ease of business permits granted to investors and limited regulations within specific scopes, while Malaysia has established more complex regulations regarding green investments, ensuring that permits are not issued arbitrarily.

Global economic uncertainty has raised concerns among the public, triggering actions to secure economic stability by investing, especially in gold and bitcoin. This study uses a comparative quantitative method, with the aim of comparing the returns, risks, and performance of the two investment instruments. The population in this study is in the form of data on the monthly closing prices of gold and bitcoin for the period of January 2019 – April 2025 which totals 152 data, consisting of 76 data from each variable. Data analysis was carried out by calculating returns, risks, Sharpe, Treynor and Jensen indices. The three indices are widely used performance measurement methods and have included return and risk factors in their measurements. The results of this study show that there is a significant difference between the return of gold and bitcoin, while for the risk variable between the two, there is no significant difference. Performance based on the Sharpe method also showed no significant difference between the two. However, for performance measurement using the Treynor and Jensen methods, significant differences were obtained between the two instruments. Overall, bitcoin offers higher profit potential than gold, even more so for investors who can accept high volatility. However, the decision to choose an investment instrument still depends on the risk profile of each investor.

The Organization of Islamic Cooperation (“OIC”) seeks to enhance economic collaboration between its member states, as outlined in the OIC Charter. Its key efforts is the Agreement for Promotion, Protection and Guarantee of Investments among OIC Member States (“OIC Investment Agreement”), which provides safeguards for cross-border investments and outlines procedures for resolving disputes between investor-states. Article 17 of the Agreement allows for dispute resolution through conciliation or arbitration. However, the lack of a dedicated dispute resolution body and clear procedural mechanisms has led to uncertainty and differing interpretations, weakening its effectiveness. This article explores the OIC’s role in investor-state dispute settlement (ISDS) under the Investment Agreement. It highlights the need for a more structured and permanent mechanism to ensure fair and consistent resolution of ISDS cases, in alignment with the objectives of the OIC Charter.

Technological advancements have driven the growth of the financial industry in Indonesia. A more complex financial system provides benefits but also raises issues, such as the rise of illegal investments by business entities without official authorization. Investment involves allocating capital with the expectation of future profits. The growing middle class and economic development in Cangkring Village have increased public interest in investing. Unfortunately, many are tempted by high returns with minimal capital without considering legality. This community service program, as part of the Tri Dharma of Higher Education, aims to educate the public about legally compliant investments. The activities were conducted through lectures and participatory methods. The results indicate that public awareness of investment remains low due to limited financial literacy. Further education is needed to help people distinguish between legal and illegal investments, ensuring they invest safely and in accordance with applicable laws.

The function of Prosecutorial Intelligence (Intel Kejaksaan) holds a crucial strategic role, not only in supporting prosecution duties but also in crime prevention, safeguarding national development, and recovering state assets. Despite having a strong legal basis and a broad mandate, this function often faces operational challenges, data integration issues, and resource optimization constraints that limit its effectiveness within the dynamic law enforcement ecosystem. This research aims to deeply analyze the role and challenges of Prosecutorial Intelligence and formulate a model for optimizing its function to enhance the effectiveness of law enforcement in Indonesia. The research methodology employed is normative and sociological juridical with a qualitative approach, gathering data through literature review, regulatory study, and in-depth interviews with practitioners and academics. The findings indicate that the optimization of the Prosecutorial Intelligence function requires three main pillars: (1) Enhancing the capacity and professionalism of human resources (HR) through modern intelligence training and digital forensics. (2) Integrating and ensuring interoperability of the intelligence information system with other law enforcement agencies (Police, KPK, PPATK) to build a comprehensive intelligence big data. (3) Expanding the spectrum of intelligence operations, shifting from a traditional focus on corruption crimes to transnational crimes, cybercrime, and securing strategic national investments. This optimization is expected to transform Prosecutorial Intelligence into a proactive, data-oriented strategic early warning system capable of supporting Prosecutors in making evidence-based decisions, thus achieving effective, just, and impactful law enforcement for the community.
