Abstract

Inflation is one of the key economic indicators that reflects the general increase in the prices of goods and services. Monetary policy plays a crucial role in controlling inflation through instruments such as interest rates, exchange rates, and money supply. This study aims to analyze the impact of monetary policy on inflation in Indonesia using quarterly time series data from the period 1993–2024. The analytical method employed is multiple linear regression with the Ordinary Least Squares (OLS) approach after ensuring data stationarity through the Augmented Dickey-Fuller (ADF) test. The findings indicate that (1) interest rates have a negative and significant effect on inflation, with a coefficient of -0.0424 (p-value = 0.0000), meaning that an increase in interest rates can suppress inflation. (2) The money supply has a positive and significant effect on inflation, with a coefficient of 4.1602 (p-value = 0.0094), indicating that an increase in money supply tends to raise inflation. Meanwhile, (3) the exchange rate does not have a significant effect on inflation (p-value = 0.1726). The F-test results show that the overall regression model is significant (p-value = 0.000004), with an R² value of 20.25%, meaning that the monetary policy variables used in this study explain only a small portion of the variation in inflation in Indonesia.

Abstract

Energy consumption is a vital aspect in sustainable development that is influenced by various factors, including urbanization, population, and economic growth. This study aims to analyze the effect of urbanization, population, and economic growth on energy consumption in Indonesia during the period 1965–2023. Secondary data were obtained from Ener Data and the World Bank, including energy consumption, urbanization rate, population size, and economic growth. The analysis was conducted using time series data regression, after passing the stationarity test, and classical assumptions. The results showed that urbanization had a negative and significant effect on energy consumption with a regression coefficient of -7.280276 and a p-value of 0.000. Population had a positive and significant effect with a regression coefficient of 20.89002 and a p-value of 0.000. Economic growth had a positive and significant effect on energy consumption with a coefficient of 14.77433 and a p-value of 0.000. These findings emphasize the importance of energy efficiency in dealing with population growth and urbanization dynamics in Indonesia.

Abstract

This study aims to analyze and identify the influence of the Information and Communication Technology Development Index (IP-ICT) on income inequality in Indonesia. This study uses panel data from 34 provinces during the period 2015-2023. The analysis method used is beta regression. The results of the analysis show that ICT Development Index has a positive and significant effect on income inequality. These findings provide an illustration that ICT Development Index will drive income inequality up. Because non-inclusive ICT development can strengthen the dominance of certain groups in accessing digital-based economic opportunities, the government needs to design affirmative policies to ensure that the benefits of digital transformation can be enjoyed equally by all levels of society.
