INTRODUCTION
Indonesia as a developing country that adheres to the freefloating exchange rate system has experienced fluctuating exchange rate movements. President Joko Widodo gathered economic ministers and businessmen to discuss anticipatory measures to weaken the rupiah against the US dollar that weakened currencies and economic slowdown as well experienced by other countries, due to the devaluation of the Chinese yuan and the planned increase in interest rates by the US Central Bank, the drop in the rupiah exchange rate was caused by selling on the stock market not only in Indonesia but also globally.
JISDOR data (Jakarta Interbank spot Dollar rate), the rupiah exchange rate against the US dollar has experienced sharp fluctuations from the Rp.11,993 figure, -in October 2014 continued to fluctuate to break the highest level at Rp. 14,728, which occurred in September 2015 from the Bank Indonesia website (www.bi.go.id).
The phenomenon of exchange rate fluctuations requires serious handling, because it will affect the level of confidence in the domestic currency so that it will change people's behavior in using money, change investors' decisions in investing their funds and will tend to interfere with foreign trade activities, because most of their trading activities are assessed by US dollar currency. So that will affect the performance of an economic activity in a country which also affects the economic conditions in that country. This is consistent with research conducted by Muchlas and Alamsyah (2015) in which a sudden and large increase in inflation in a country will cause an increase in imports by the country of various goods and services from abroad, so that more foreign exchange is needed to pay for import transactions The funds will result in increased demand for currencies The exchange rate is one of the important prices in an open economy because it is determined by the balance between demand and supply that occurs in the market. The free foreign exchange system and coupled with the implementation of the freely floating exchange rate system in Indonesia since 1997, caused exchange rate movements in the market to be very vulnerable by the influence of economic and non-economic factors. According to (Agustina, Reny, 2014), simultaneously export, import, the rupiah exchange rate and inflation rate affect Indonesia's foreign exchange reserves and partially export has a positive and significant effect on Indonesia's foreign exchange reserves, the rupiah exchange rate has a significant negative effect on Indonesia's foreign exchange reserves while the import and rupiah exchange rate do not affect Indonesia's foreign exchange reserves. In contrast to (Fabiano, Daniel, Kelmara, 2014) there is a positive influence of GDP and the negative influence of inflation and the exchange rate on Bovespa, an exception from the interest rate (Selic) which is not significant with the stock index. H1: there is no significant difference in the fluctuation of the rupiah against the US dollar in the Jokowi Government and before the Jokowi Government seen from the inflation rate H2: there is no significant difference in the rupiah exchange rate against the US dollar in the Jokowi Government and before the Jokowi Government seen from the interest rate, H3 : there is a significant difference in the fluctuation of the rupiah exchange rate against the US dollar in the Jokowidan Government before the Jokowi Government seen from the amount of money in circulation, H4: there is no significant difference in the rupiah exchange rate fluctuation against the Jokowi Government and before the Jokowi Government seen from the H5 Export: no there is a significant difference in the rupiah exchange rate fluctuations against the US dollar in the Jokowi Government and prior to the Jokowi Government seen from Imports

Fluctuations in the rupiah exchange rate against the US dollar
Exchange rate fluctuations are the fluctuations in the value of one currency against another from various countries. Fluctuations in the exchange rate will cause what is referred to as currency exchange risk. This risk will be seen in the value of a strong and weak currency (Simi., Et.Al2015).
A currency is said to be strong if there is a surplus in the balance of payments because revenues are greater than payments (credit transactions> debit transactions), otherwise, it is said to be weak if the balance of payments is a deficit, namely payments greater than revenues (debit transactions> credit transactions).

Exchange rate
According to Joesoef (2008: 23), the exchange rate (exchange rate) is the amount of a particular currency that can be exchanged against one unit of another currency. According to Muhammadinah (2011), Foreign exchange rates are the ratio of a country's currency exchange rates with other countries.
A. Types of exchange rates in Indonesia 1. Judging from the period of delivery of funds according to Joesoef (2008,3031) the exchange rate can be classified into: a) Spot rate: b) Forward rate 2. Judging from the type of transaction, the exchange rate can be classified into a) Buying rate b) Selling rate c) Mid-term

Inflation
According to Ristaino and Puryani (2011: 181) inflation is a situation where the price of goods and services increases, for example, apartment rentals, book prices, haircuts, wholesalers and almost everything, the longer it tends to increase.

Interest rates
According to Ristono and Puryani (2010) Interest (interest) can be interpreted as money paid for the use of a saved amount of money (savings, deposits, SBI, etc.),

Amount of Circulation (JUB)
According to Sukirno (2012: 267), money is objected that are approved by the community as an intermediary for conducting trade/trade. "Approved" means there is an agreement from the community to use the object as an exchange tool.

International trade
International trade is a trade that occurs not only among communities in an area or a country but extends to trade between countries (foreign trade).

a. Export
Exports are one indicator to find out how much economic growth in a country. From export activities can be guaranteed business activities in the real sector are increasingly maintained.

b. Import
According to Agustina and Reny (2014) import transactions are traded by entering goods from abroad into Indonesian customs by complying with the provisions of the prevailing laws and regulations

B. Theoretical Thought Framework
Jokowi's administration

B. Population and Samples
The population in this study is the currency or exchange rate in Indonesia. Samples according to Martono (2010: 66) are some members of the population selected using certain procedures so that they are expected to represent the population. The sampling technique used is saturated samples where all populations are used as a sample. then the sample of this study is the rupiah exchange rate against the US dollar, using a sample in the Jokowi administration of 13 months and before the Jokowi administration of 13 months with a total of 26 (twenty-six) samples or observations.

C. Type of Research
The type of research used is explanatory research. Explanatory research is research that tries to explain the phenomena that exist (Zainuldan Muchlas, 2015).

E. Types and Data Sources
The type of data used in this study is quantitative data, where the data source used is secondary data. This study uses monthly time series data. Secondary data used are:

F. Data Collection Technique
Collecting data in a study is intended to obtain materials that are relevant, accurate and realistic. Because macro data, data collection techniques used in this study are documentary techniques, namely getting information through notes, literature, grooming documentation and other relevant research. In addition, there are also written report data related to this research from various literature studies obtained from related agencies, websites, and research journals.

Data Analysis Techniques
Analysis with the Normality test and by using the T-Test Paired sample test. The significant level taken in this study is 5% or a confidence level of 95%. Test the hypothesis used in this study is valid, if the significant (2tailed) value is smaller than α = 0.05, then Ha cannot be rejected, whereas if the value is significant (2-tailed) greater than α = 0.05, then Ho is rejected.

AND DISCUSSION a. Paired sample T-Test
Based on the results of the analysis carried out by researchers used to answer the results of testing the differences between the two paired or related samples can be shown in the  the Jokowi administration so that H3 states that there is a significant difference in the rupiah exchange rate fluctuations against the US dollar in the Jokowi government and when the Jokowi Government is seen from the amount of money circulating rejected 4. That there were differences in exports before and during the Jokowi administration so that H4 stated that there was no significant difference in the rupiah exchange rate fluctuations against the US dollar in the Jokowi Government and before the Jokowi Government was seen from Export rejected 5. That there are differences in imports before and during the Jokowi administration so that H5 states that there is no significant difference in the rupiah exchange rate fluctuations against the US dollar in the Jokowi Government and before the Jokowi Government was seen from Imports rejected 6. Based on test (partial test), before the Jokowi government could only know interest rates that significantly affected the rupiah exchange rate against the US Dollar and the variable inflation, the money supply, exports and imports were not significant to the rupiah exchange rate against the US Dollar, while the Jokowi government was variable inflation, interest rates, the amount of money in circulation, exports, imports are not significant to the rupiah exchange rate against the US Dollar. the results of this study differ from the research of Triyono (2008) which states that the results of short-term analysis of inflation, money supply, interest rates, imports have a significant effect against the exchange rate, while in the long run the variable inflation, interest rates, imports have a significant positive effect on the exchange rate, the variable amount of money
