The alarming trend of CO₂ emissions in Indonesia merits a reinvestigation into the determinants in a bid to conserve the environment. In the literature, in Indonesia, three potential determinants, namely, energy, foreign direct investment, and corruption, have been identified to harm the environment. However, their effects are still undetermined. Thus, this study aims to examine the relationships between corruption (COR), energy use (ENY), foreign direct investment (FDI), and CO₂ emissions in Indonesia. The autoregressive distributed lag (ARDL) approach was used to analyse data for 36 years, from 1984 to 2020. The results reveal that corruption contributes to greater environmental degradation in the short run, while foreign direct investment does not. However, in the long run, corruption and energy use can positively affect environmental degradation, but foreign direct investment can reduce environmental degradation in Indonesia. This study also found two other factors, namely, economic growth and urbanisation, which can affect the environment with mixed findings. These findings are indispensable for policy formulation in Indonesia as Indonesia is a rapidly developing country that depends on good environmental quality to ensure future growth and sustainable development.

Despite the recent reduction in the poverty rate in Indonesia, income inequality has not shown any improvement. Income inequality, also known as income disparity, has been a prolonged issue in Indonesia and has caused great dissatisfaction among the public. Many of them do not feel an improvement in their wellbeing. Most studies explore these issues based on microeconomics perspectives, and limited studies focus on macroeconomic determinants. Thus, it is imperative to investigate the potential macroeconomic determinants of income inequality in Indonesia, particularly energy consumption (ENC), corruption (COR), foreign direct investment (FDI), and other supporting determinants such as economic growth (GDP), financial development (FD), and CO₂ emissions. Data from 1984 to 2020 were collected and analyzed, employing the autoregressive distributed lag (ARDL) approach. The findings indicate that economic growth, corruption, and FDI can contribute to a smaller gap between the rich and the poor. At the same time, greater CO₂ emissions can intensify income inequality in Indonesia both in the short and long run. Pollution, as captured by CO₂ emissions, can affect the health of the poor. Health problems create difficulties for poor people to work and reduce the probability of earning income, ultimately widening income inequality. FD and energy use, on the other hand, do not influence income distribution in the long and short run. The findings indicate that boosting economic growth and FDI significantly reduce income disparity in Indonesia. Various policy recommendations are suggested in these studies based on the long-run outcomes.

Purpose: This paper aims to identify variables that determine the differing levels of environmental quality on Java and other islands in Indonesia.Design/methodology/approach: Using a quantitative approach, secondary data were sourced from the Central Statistics Agency and the Ministry of Environment and Forestry. The data were obtained through the collection of documentation from 33 provinces in Indonesia. The analytical approach used was discriminant analysis. The research variables are Trade Openness, Foreign Direct Investment (FDI), industry, HDI and population growth.Findings: The variables that distinguish between the levels of environmental quality in Indonesian provinces on the island of Java and on other islands are Industry, HDI, FDI and population growth. The openness variable is not a differentiating variable for environmental quality. The most powerful variable as a differentiator of environmental quality on Java Island and on other islands is the Industry variable.Research limitations/implications: This study has not classified the quality of the environment based on the Ministry of Environment and Forestry's categories, namely, the very good, good, quite good, poor, very poor and dangerous. For this reason, further research is needed using multiple discriminant analysis (MDA).Practical implications: Industry is the variable that most strongly distinguishes between levels of environmental quality on Java and other island, while the industrial sector is the largest contributor to gross regional domestic product (GDRP). Government policy to develop green technology is mandatory so that there is no trade-off between industry and environmental quality.Originality/value: This study is able to identify the differentiating variables of environmental quality in two different groups, on Java and on the other islands of the Indonesian archipelago.

The purpose of this study is to analyze the impact of globalization on MSMEs in Indonesia in the context of prior of the Covid-19 pandemic. The study applied descriptive qualitative approach and used documentation as the data collection in which the data were retrieved from journals, web, and other relevant sources. The results concluded that MSMEs in Indonesia with 10% contribution had not been able to significantly support the Indonesian economy due to various obstacles. The government has taken various ways to overcome this problem and expected that by 2024 MSMEs can support 17% of the national economy.
