Global financial institutions have raised interest rates to lower inflation, which has led to this problem. This study aims to evaluate the effect of interest rates and inflation on Indonesia's economic growth and compare the performance of machine learning models, specifically Random Forest and XGBoost, in analyzing the impact of inflation. A qualitative methodology was used for the literature survey, while the quantitative approach involved the implementation of machine learning algorithms using the Ensemble Method. The results show that Random Forest performs better than XGBoost in predicting the impact of inflation on economic growth, with MSE values of 0.799 and 0.864 and MAE of 0.576 and 0.619, respectively. In addition, the R-squared value of Random Forest 0.908 is also higher than that of XGBoost 0.901, indicating that the model can better explain the variation in the target data. The practical implication of this study is that the Random Forest model can be more effectively used in analyzing the impact of inflation on Indonesia's economic growth. Recommendations for future research include exploring other methods and using more extended time series to deepen the understanding of the relationship between interest rates, inflation, and economic growth.  \nKeywords—Machine learning; ensemble method; regression; impact of inflation.  \nManuscript received 19 Feb. 2024; revised 20 Apr. 2024; accepted 31 May 2024.

INTRODUCTION  \nHigh inflation rates and sluggish economic growth are common economic issues developing nations face. It is common to link inflationary features to domestic variables. Economic growth rates can be considerably raised by investing in market output, infrastructure, education, and preventive healthcare, but not always by spending on investments [1]. Furthermore, other factors, including interest and unemployment, are also linked to inflation. Many scholars have recently contended that globalization has made the global economy have a larger influence on inflation production than domestic variables.  \nNations worldwide are taking notice of the warnings about a worldwide recession in 2023. The world's financial institutions are to blame for this issue since they are increasing interest rates to rein in inflation. Although many economists argue that Indonesia is still far from entering a recession, this does not mean the country will be immune to the effects of the global economic slump [2]. Prediction is a straightforward  \nand powerful technique for assessing a model's predictive power that social scientists can use to their advantage in their empirical research [3]. In machine learning, an artificial intelligence field, computers are taught to use intricate mathematical algorithms to anticipate outcomes or spot patterns in data [4]. Machine learning techniques, including XGBoost Regression and Random Forest Regression, can forecast economic growth and give governments helpful information about how to plan for inflation [5]. Regression analysis is one of the procedures most often utilized by machine learning models.
