Climate change is a global concern driven by increasing pollution through rising CO2 emissions and growing ecological footprint from human activities. This research investigates how environmental quality (proxied by CO2 emissions and ecological footprint) in Indonesia is affected by multiple factors, including natural disasters, fossil fuels, renewable energy consumption, economic growth, and capital formation from 1965 to 2022. The analysis employs the Autoregressive Distributed Lag (ARDL) model, with robustness ensured using Dynamic Ordinary Least Squares (DOLS), followed by Granger causality tests to examine dynamic relationships between variables. The findings show that natural disasters, fossil fuel consumption, and economic growth contribute to increasing CO2 emissions in the long run, while renewable energy consumption helps reduce them. Natural disasters exhibit a negative but insignificant impact on the ecological footprint. Economic growth increases the ecological footprint, whereas capital formation helps reduce it in the long run. In the short run, fossil fuels are found to increase CO2 emissions, while renewable energy reduces them. Natural disasters are found to increase the ecological footprint. Additionally, the Granger causality test confirms a unidirectional relationship from both natural disasters and economic growth to environmental quality. This study recommends that Indonesia implement integrated strategies focused on accelerating green energy adoption and enhancing disaster resilience to achieve environmental quality.

This study investigates the scholarly landscape of General Equilibrium (GE) model applications within the field of energy research through a bibliometric lens. Utilizing a dataset of 864 journal articles indexed in Scopus from 1974 to 2022, the research maps publication trends, identifies leading contributors, and uncovers prevailing thematic clusters within the field. The analysis employs VOSviewer to visualize co-authorship networks, as well as institutional and country-level productivity, source relevance, and keyword co-occurrence patterns. Results reveal that China, the United States, and Japan are the most prolific countries, while Energy Policy and Energy Economics emerge as the most influential journals. Among the authors, Masui T. stands out as the most productive, while Paganetti registers the highest number of citations, reflecting a significant scholarly impact over recent years. Keyword mapping highlights dominant research themes centered on "computable general equilibrium analysis," "computable general equilibrium model," and "emission control," reflecting the field’s alignment with climate-related energy policy evaluation. This bibliometric overview not only provides a structured understanding of intellectual developments in GE-energy research but also identifies underexplored areas that warrant further investigation—particularly the integration of GE models with renewable energy transitions in developing economies and the incorporation of behavioral and distributional dimensions within energy policy assessments. The study contributes to the advancement of interdisciplinary dialogue by informing future research directions and supporting evidence-based policymaking in the energy-climate nexus.

This study examines the impact of capital structure and financial performance of Islamic banks on price stability in Indonesia using an Autoregressive Distributed Lag (ARDL) model with quarterly data from 2014 to 2024. Key variables include the Capital Adequacy Ratio, Total Regulatory Capital, Tier 1 Capital, Risk-Weighted Assets, Net Income, and the Consumer Price Index. Long-term findings reveal that robust capital indicators enhance price stability by strengthening banks' resilience and credit capacity. In contrast, Net Income mitigates inflationary pressure in the long run but intensifies it in the short term. The error correction term confirms rapid adjustment toward equilibrium after short-term shocks. These results underscore the critical role of sound capital and profitability in reinforcing Islamic banks’ contribution to Indonesia’s monetary policy, offering valuable insights for policymakers and regulators in promoting macroeconomic stability.

This study investigates the determinants of poverty across Indonesian provinces with a particular focus on the role of social assistance expenditure. Using provincial panel data from 2015 to 2024, the analysis combines information on poverty headcount ratios with fiscal, economic, and political variables, namely social assistance per capita, gross regional domestic product (GRDP) per capita, unemployment rate, and election years. The study employs a fixed effects panel regression model, selected on the basis of specification tests, and incorporates one-year lagged values of social assistance and GRDP per capita to capture the delayed effects of fiscal and economic policies. The results reveal that social assistance has a negative but modest effect on poverty, indicating its limited yet relevant role in supporting vulnerable households. GRDP per capita emerges as the strongest determinant, confirming the importance of inclusive growth in driving poverty reduction, while unemployment significantly worsens poverty outcomes. In addition, poverty rates tend to fall in election years, reflecting the influence of political cycles on welfare spending. Overall, the findings underscore that poverty reduction in Indonesia requires multidimensional strategies that combine sustained economic growth, labor market improvements, and well-targeted social assistance, supported by institutional safeguards that ensure consistency beyond short-term political incentives.
