Abstract

Purpose-This study aims to analyze the effect of corporate social responsibility on the profitability of listed banks in Indonesia and analyze leverage as the moderating variable. Design/Methodology/Approach-This research uses data from 14 listed banks in the Indonesia Stock Exchange from 2017-2021. The equations to analyze the influence of corporate social responsibility and some control variables (firm size, capital adequacy ratio, leverage, and inflation) on profitability and the influence of leverage as a moderating variable are estimated using fixed effect panel data regression. Findings-The results of this research show that firm size, capital adequacy ratio, leverage, and rate of inflation variables have a positive influence on profitability. Meanwhile, corporate social responsibility and the moderating effect of leverage do not significantly influence profitability. Research limitations/implications-The research findings are expected to become a reference for the investor and the bank management on the influence of corporate social responsibility on a listed bank's profitability and the effect of leverage as a moderating variable. Originality/value-As an intermediary, banks have different types of leverage than non-bank companies. This study analyzes the impact of corporate social responsibility with leverage as a moderating variable on the profitability of listed banks in the Indonesian Stock Exchange.

Abstract

ABSTRACTThis study aims to analyze the determinants of consolidation strategy based on the evaluation of internal and external factors of the Sharia Business Unit of Regional Development Banks (UUS BPD) and to obtain an equation model of UUS BPD consolidation strategy towards the level of stability. This research uses a quantitative approach with panel data regression. All independent and dependent variables are tested with Ordinary least squares to obtain an equation model from the regression test. The results of the study indicate that the determinants of the results of the merger consolidation model, namely, ROA, LAR, RGEC, IPTIK, and GDP, have a positive effect on the level of stability of the UUS BPD merger model, and concentration (Herrfibdhal Hiermans Index) has a negative and significant effect. However, IM has a positive but insignificant effect, and TA has a negative but insignificant effect. The study's results simultaneously show that the merger consolidation model's determinants affect UUS BPD's stability by 22,50%. By optimizing internal factors (finance, technology, governance) and synergy with economic growth, UUS can be more stable and ready to face financial challenges in the future.ABSTRAKPenelitian ini bertujuan untuk menganalisis faktor penentu strategi konsolidasi berdasarkan evaluasi faktor internal dan eksternal Unit Usaha Syariah Bank Pembangunan Daerah (UUS BPD) dan untuk memperoleh model persamaan strategi konsolidasi UUS BPD terhadap tingkat stabilitas. Metode penelitian ini menggunakan pendekatan kuantitatif dengan regresi data panel. Seluruh variabel bebas dan variabel terikat diuji dengan Ordinary least squares untuk memperoleh model persamaan dari uji regresi. Hasil penelitian menunjukkan bahwa determinan hasil model konsolidasi merger secara parsial yaitu; ROA, LAR, RGEC, IPTIK dan PDB berpengaruh positif terhadap tingkat stabilitas model merger UUS BPD, dan konsentrasi (Herrfibdhal Hiermans Index) berpengaruh negatif dan signifikan. Namun, IM berpengaruh positif tetapi tidak signifikan dan TA berpengaruh negatif tetapi tidak signifikan. Hasil penelitian secara simultan menunjukkan bahwa faktor-faktor determinan model konsolidasi merger berpengaruh terhadap tingkat stabilitas UUS BPD sebesar 22,50%. Dengan mengoptimalkan faktor internal (keuangan, teknologi, tata kelola) dan sinergi dengan pertumbuhan ekonomi, UUS dapat lebih stabil dan siap menghadapi tantangan keuangan di masa depan.

Abstract

Renewable energy, being environmentally friendly, needs to see increased utilisation due to the detrimental effects of fossil fuel usage on human life. The government has promoted the Energy Transition programme, yet the adoption of renewable energy remains limited, primarily due to financing challenges and the economic viability of projects. The government cannot tackle this alone; it requires the support of financing schemes backed by social funds from the community. In this regard, aligning with the objectives of Shariah (maqasid shariah), the role of Islamic Social Finance can be enhanced within the concept of Islamic Blended Finance to fund renewable energy projects that have social and environmental impacts. The aim of this paper is to develop the role of Islamic Social Finance within Islamic Blended Finance and the necessary regulations, making it a feasible financing scheme that can offer an alternative solution to the funding challenges faced by renewable energy projects. Previous research is limited due to the relative novelty of the topic. This study employs a mixed-methodology approach, incorporating literature review supported by secondary data, as well as primary data from interviews with competent informants.

Abstract

This research aims to analyze efficiency  and  profitability  of  Islamic  Rural  Banks  in  Indonesia  using Variable Returns to Scale model of Data Envelopment Analysis and efficiency-profitability matrix.  The  results  of  this  research  show  that  most  of  Islamic  Rural  Banks  are included in the Dog quadrant (high efficiency but low profitability) and Sleeper quadrant (low efficiency but high profitability). Meanwhile, the result of correlation analysis between efficiency and profitability indicates that efficiency has a negative correlation with profitability. Negative correlation of efficiency and profitability is in accordance with the result of efficiency-profitability matrix. The results of this research show that not all of Islamic Rural Bank which have high efficiency are also having high profitability.DOI:10.15408/aiq.v7i1.1354

Abstract

This study aims to analyze the influence of peer banks on the liquidity management of Islamic banks in Indonesia and whether such influence is robust during the periods of the global financial crisis. This research uses fixed-effect panel data regression with robust standard error and the data of Islamic banks in Indonesia for the years 2007-2020. This research finds that peer-banks have a negative impact on Islamic bank liquidity, and it is robust in the global financial crisis periods. This study contributes to the policymakers and literature regarding the peer bank effect, especially in the liquidity management of Islamic banks. The liquidity management of Islamic banks is not only influenced by the conditions of the Islamic banks themselves but also affected by the behavior of other Islamic banks. AbstrakPenelitian ini bertujuan untuk menganalisis pengaruh peer bank terhadap pengelolaan likuiditas bank sharia di Indonesia dan apakah pengaruh tersebut tetap ada selama periode krisis keuangan global. Penelitian ini menggunakan regresi data panel fixed-effect dengan robust standard error dan data bank sharia di Indonesia tahun 2007-2020. Penelitian ini menemukan bahwa peer-banks berdampak negatif terhadap likuiditas bank sharia, dan pengaruh tersebut tetap ada pada periode krisis keuangan global. Hasil penelitian ini memberikan kontribusi bagi pengambil kebijakan dan literatur mengenai adanya peer bank effect khususnya dalam pengelolaan likuiditas bank sharia. Pengelolaan likuiditas bank sharia tidak hanya dipengaruhi oleh kondisi bank sharia itu sendiri, tetapi juga dipengaruhi oleh perilaku bank sharia lainnya.

Abstract

A strategic option to accelerate core capital fulfilment and the conversion of sharia business units into full-fledged sharia commercial banks is consolidation through mergers and joint business groups. This approach is particularly relevant for sharia business units under regional development banks that occupy the defensive quadrant in terms of competitiveness and financial performance. This study develops an empirical model to evaluate the influence of internal and external factors on the stability of UUS BPD and to simulate potential resilience gains post-consolidation. Using panel data from 12 UUS BPD between Q1 2012 and Q4 2022, the research applies cluster analysis, the fixed effect model, the analytic hierarchy process, and merger simulation. Results reveal that consolidation supported by profitability, asset growth, and sound risk management significantly improves financial stability. Merger simulations yield Z-scores of 1.1–2.6, indicating moderate stability, while the joint business groups simulation with BJB Syariah shows steady improvement from baseline. Consolidation serves not only as a growth strategy but also as a survival mechanism for Sharia Business Units BPDs facing regulatory and structural challenges, with both merger and Joint Business Groups options classified as moderately prospective for post-consolidation sustainability.

Abstract

This study examines the impact of United States reciprocal tariff announcements on stock market reactions in ASEAN countries using six major indices: IHSG (Indonesia), STI (Singapore), FTSE KLCI (Malaysia), SET (Thailand), PSEi (Philippines), and VN Index (Vietnam) in 2025. Three events are analyzed: the initial tariff announcement on April 2, 2025, the tariff pause announcement on April 9, 2025, and the tariff adjustment announcement on August 1, 2025. An event study method is applied with a 120-day estimation period and an event window from t0 to t+3 using the mean-adjusted model. Hypothesis testing employs the one-sample t-test or the Wilcoxon signed-rank test based on data normality. The results show that the initial tariff announcement generated significant negative cumulative abnormal returns, particularly in Vietnam and Singapore. The tariff pause announcement produced significant positive abnormal returns, indicating a market rebound following reduced policy uncertainty. The tariff adjustment announcement resulted in more moderate reactions, with insignificant daily abnormal returns but a positive cumulative effect. Overall, ASEAN stock markets react to U.S. tariff announcements, although price adjustment is not always immediate, indicating deviations from full semistrong market efficiency.

Abstract

Research Originality: This research is original in its focus on the long-run structural determinants of risk-taking in Indonesian Islamic banking. Research Objectives: The study aims to analyze how liquidity, profit-and-loss sharing (PLS), financing growth, financing-to-deposit ratio (FDR), economic growth, and inflation influence risk-taking behavior in Islamic banks. Research Methods: This study employs ARDL and Error Correction Model (ECM) techniques. The study investigates quarterly data from 2015 to 2024 to assess short-run and long-run relationships. The ECM framework provides insights into the adjustment mechanism toward equilibrium. Empirical Results: In the short run, liquidity, PLS, and financing growth significantly affect risk-taking. In the long run, liquidity has a significant negative effect, whereas PLS and Z-score exhibit a positive effect. Other variables are not statistically significant. The ECM confirms a strong adjustment mechanism, indicating that approximately 33.5% of short-run deviations are corrected toward long-run equilibrium each quarter. Implications: Policymakers and practitioners should design risk management strategies that differentiate between short-run operational adjustments and long-run macroeconomic anticipation.
