Global economic issues have significantly impacted national economic progress in recent decades, especially for developing countries such as Indonesia.  Currency exchange rates are one of the main variables that influence this economic process.  The performance of a country's external sector is largely determined by the exchange rate, which also affects a number of other macroeconomic factors.  The purpose of this study is to see how much Indonesia's economic growth is affected by the exchange rate between 1980 and 2023. Data from government agencies including the Central Bureau of Statistics and Bank Indonesia are used in this quantitative approach using a literature study approach.  The findings show that changes in the value of the rupiah, especially when depreciation occurs, have a significant influence on a number of economic factors, such as imports, exports, inflation, domestic investment, and consumption.  The competitiveness of Indonesian export goods in the global market increases with the depreciation of the exchange rate. At the same time, however, it also leads to higher prices for imported goods, increases the burden of foreign debt, and depresses people's purchasing power and domestic investment activity. The last five years of data reflect the fluctuating pattern of Indonesia's international trade, which is closely related to exchange rate conditions and global economic dynamics. Exchange rate instability creates economic uncertainty, which can hamper long-term growth. Therefore, stabilizing the exchange rate and strengthening the export sector are important strategies, supported by monetary and fiscal policies that are adaptive to global changes.

This research concludes that the Income Level (TPP) received by workers at retirement is only 10% of the last salary obtained from the mandatory pension program, a decrease in income of 90% of the last salary. The monthly living cost needs of retirees in retirement (food, monthly shopping, water costs - electricity, internet, lifestyle, health insurance, etc.) obtained data of IDR 5,600,000, - or equivalent to 56% of the last salary per month. So in actual terms, the level of retirement income (TPP) of retirees in Indonesia there is a gap of IDR 4,600,000, - or 46% less than the last salary per month. This condition causes retirees to fail to maintain their standard of living in old age, in addition to experiencing financial problems in retirement. Factors that affect the amount of a person's TPP consist of: 1) type of work, 2) pension program participated in, 3) length of service and salary amount, 4) investment return rate from the pension program, 5) government regulations, 6) macroeconomic factors and inflation, 7) health conditions of retirees, 8) family responsibilities, and 9) pension fund education determine the size of the level of retirement income. Optimizing private pension funds plays an important role in increasing TPP as a guarantee of income in retirement and creating financial independence in old age, in addition to improving quality of life. For this reason, private pension funds must be managed more optimally to achieve significant investment performance, improve pension fund literacy, target formal and informal workers, and diversify adequate products and services through digitalization of pension fund access and services to encourage significant growth in private pension fund participation.

The independent variable in this research is the variable that is manipulated and predicted to have an influence on the dependent variable. This is known by the tolerance value and Variance Inflantion Factor (VIF) value which are used to determine positive and negative values between independent variables. There is no or no multicollinearity found in the regression model. It is found that there is no multicollinearity in the Regression Model. This shows that there is a linear relationship and influences the dependent variable. Test the Coefficient of Determination (R2) to determine the contribution of variabilitate and independent variables.

The joint stock price index (IHSG) as a benchmark for the progress of the capital market in Indonesia. The purpose of this study was to analyze the effect of Macro Variables on the Composite Stock Price Index (JCI) for the period 2010 to 2021. The macro variables used were Inflation, Economic Growth, Dollar Exchange Rate and SBI or 7 Day Repo Rate against the JCI. The number of years in the sample is 12 years, from 2010 to 2021. Multiple linear regression analysis, T test, F test, coefficient of determination test using SPSS Version 26 software. The conclusion is that gold price and Lq45 has  significant effect on the JCI, while the others macro variable, have no significant effect on the JCI. Simultaneously, all macro variables have a significant effect on the JCI.
