This research to analyze the contribution of variables from three economic policies, with monetary policy through interest rate variables, exchange rates, and money supply in facing economic recession. Where the fiscal policy variable is through tax value. Then macroprudential policy through Non Performing Loan and Capital Adequacy Ratio variables. This study uses secondary data or time series, namely from December 2019 to February 2021. The data analysis model in this study is the Vector Autoregression (VAR) model which is seen from being sharpened with Impulse Response Function (IRF) analysis and Forecast Error Variance Decomposition (FEVD), Panel ARDL, and Different Tests. The results of the IRF analysis show that the stability of the response of all variables is formed in period 8 or the medium and long term, where the response of other variables to changes in one variable shows different variations, both from positive responses to negative responses or vice versa, and there are variables whose responses remain positive or remain negative from the short term to the long term. The results of the FEVD analysis show that for the short-term inflation variable it is influenced by inflation itself and in the medium and long term it is influenced by interest rates. For the JUB variable in the short term it is influenced by JUB itself and in the medium and long term it is influenced by NPL. For the interest rate variable in the short term it is influenced by JUB while in the medium and long term it is influenced by the exchange rate itself and CAR. For the tax variable in the short, medium and long term it is influenced by the tax itself and JUB. For the NPL variable in the short, medium and long term it is influenced by JUB and tax. For the CAR variable in the short, medium and long term it is influenced by JUB and tax. Then the results of the ARDL Panel analysis show that the country that is able to become a leading indicator in controlling the economic recession in the Four of The Group Twenty, namely Turkey, is only done by interest rates. While South Africa is done by interest rates, taxes, NPL, and CAR. For Russia, it is done by all variables, namely the amount of money in circulation, interest rates, exchange rates, taxes, NPL, and CAR. Meanwhile, Indonesia is carried out by exchange rates, taxes, NPL and CAR.

Viral evolution is a subdiscipline of evolutionary biology and virology that focuses on the evolution of viruses. Many viruses, especially RNA viruses, have relatively high mutation rates and short production durations (on the order of one point mutation or more per genome per round of replication). The rapid pace of viral mutation paired with natural selection enables viruses to rapidly adapt to changes in the host environment, despite the fact that the majority of viral mutations offer little benefit and frequently prove to be harmful. Additionally, because viruses often make several copies in an infected host, altered genes can be rapidly transmitted to a large number of offspring. The high mutation rates of RNA viruses, which are the result of an error-prone RNA-dependent RNA polymerase, make them a veritable gold mine for researchers interested in discovering evolutionary novelty and developing new methods to study evolution in action. There are two different forms of genetic changes: antigenic drift and antigenic shift. This article covers briefly the evolution of viruses in terms of genetic variation.  

As a developing country, Indonesia has an economic structure dominated by the agricultural sector, making it vulnerable to disruptions to economic stability. Economic growth is an indicator showing that the economic level of society in general has increased in terms of consumption habits and people's purchasing power for goods and services. However, excessive consumption leads to a consumer society and inflation. This study aims to look at the causality between inflation, consumer price index, interest rates, gross domestic product, and exchange rates using the time series approach in the form of the quarterly period 2014Q1 to 2022Q2 in Indonesia using the VAR (Vector Autoregression) method. The research results show that inflation is related to or influenced by the consumer price index and savings. As for the Exchange Rate, Gross Domestic Product and Interest Rates have no effect on inflation.

There are differences in the influence of inflation and interest rates on profitability (ROA) in banks that fall into categories on the IDX. Objectives: 1. Determine whether interest rates can partially influence profitability (ROA). 2. Determine whether inflation can partially influence profitability (ROA). 3. Determine how the inflation rate and interest rates (Bi Rate) affect profitability (ROA) simultaneously. This elitism in testing is carried out to determine the influence when inflation and interest rates occur which can affect profitability (ROA) in banking. In this research the researcher used the Associative Research method. The samples taken in the research carried out were 4 banks registered on the IDX. Results: 1. Interest rates have a partial effect on profitability (ROA). 2. Inflation also partially influences profitability (ROA). 3. Inflation and interest rates simultaneously have an influence, namely simultaneously on profitability (ROA).

Destination from study this that is for test variable Interest Rates, Inflation , Total Money Supply and GDP how much big in take effect to EXCHANGE variable . And for knowing is panel level _ ethnic group interest , inflation , money supply , unemployment , investment , and GDP have an effect positive and significant to exchange rates in America, Australia, China, Canada , Indonesia, Japan , South Korea, Malaysia, Singapore, Russia and Thailand. Approach study this is study associative / quantitative with the Simultaneous model and the ARDL Panel where aim see linkages Among independent variables and dependent variables that spread panel in Top Major Exchange Rate countries in 11 APEC Countries. Study this conducted against 11 countries with exchange rate strongest in the APEC countries in the world (America, Australia, Malaysia, Singapore, South Korea, Japan , China, Indonesia, Canada , Russia , and Thailand). The ARDL Panel Analysis results show that the Leading Model Control indicators Exchange Rate System Through the Post -Covid-19 Open Economy Model, the Top Major Exchange Rates in Eleven Apec Countries (Varies) are JUB and GDP. this _ due to the results data processing , the ROE variable is variable that gives stable influence , ie _ effect on the inside period long nor period short in give influence significant to score exchange , which is assessed from level short run and long run stability in the table result .  

This study aims to analyze the contributions of the variable interactions of monetary policy in the stability of goods and services prices. Where is the monetary  policy variable (inflation, kurs, consumer price index, gross domestic products, the money supply, and interest rates). Research in conducted in the country of Indonesia and uses secondary data or time series from 2008 to 2021. The data analysis model in this study is Simultaneous Model. Simultaneous equations to analyze the relation between independent and variable variables found in the research country. Simultaneous analysis of equations on statistical test common equation 1 suggests that variable interest rates, money distribution, exchange rates and consumer price indexes have significant adverse effects on the inflation. Whereas in the same equation 2, it suggests that gross domestic product variables have a positive relationship that is significant to the ihk. And inflation has a negative relationship significantly insignificant to consumer price index. For this reason, the researcher hopes that the monetary authority, namely Bank Indonesia, can improve monetary stability and maintain the BI rate in regulating the money supply so that it can suppress the inflation rate as an effort to stabilize the prices.
