In Act No. 23 of year 1999 on Bank Indonesia,
explained that there is a main aim and tasks of the
Bank Indonesia, which focuses on achieving and
maintaining the stability of the exchange rate of the
rupiah. Monetary instruments that a prime target to
be accomplished is the stability of rupiah value
including inflation and exchange rates. examines the
factors that influence the amount of money in
circulation.
This model is used in is the request for money
with a quadratic cost function estimation using ECM
(error correction model). The variable that is used in
is for national, money supply, interest rate Indonesia
(SNI) and exchange rates which found that the
amount of money circulating in Indonesia can
explain both phenomena of variable interest rates, to
the national level, exchange rates.
Here the money supply in the long term is
affected by the level of national and for exchange
rates. This is them is the money supply in the long
term is affected by the level of national exchange
rates for positive and negative interest rates. The
demand for money will increase if it is for real and
request refused if the nominal interest rate rises
(Manurung, 2009).
2 THEORICAL FRAMEWORK
Money demand theory aims to develop determinants
of demand for money, which is the function of
money as a means of Exchange and optimization of
the number of requests for money. The demand for
real money will be higher if real transaction is
higher, the classical theory of money demand is
reflected in Irving Fisher. Irving Fisher in the theory
of amount of money, essentially using money.
According to Keynes function Exchange not only
money but as a value such as a Bank, which was
then known as liquidity preference theory. Keynes
gives rise to uncertainty and expectations as named
approach Cambridge. However, Keynes's theory, it
is more focused on the BI rate is variable variables
important in liquid demand money (Mankiw: 2000).
Keynes in the theory of the demand for money
transaction motives,distinguishes between motive
and motives that keep the speculation. Request
money for purposes of the transaction and only in
the case, meaning that the tagline for individuals or
companies to pay cash transactions because they
think that spending often occurs earlier than the
money now (according to). This fee is not often
predetermined, so cash is needed in the hand.
Although the spending and to be expected with
money in hand, the menu is still necessary, because
to be expected is not acceptable, or transaction fees
for very important tagline is done before coming
upon request, or may transactions provide a great
advantage but with drawn before acceptance. While
the request for money for speculation, according to
Keynes, that the public wants a large amount of
money for transactions purposes, because of the
desire to give the most liquid form, apply the money.
This saves cash has a function as a value such as a
Bank or a money request for the assets of the
demand for money. Request money for speculation
this will be determined by the level of interest. The
higher the interest rate, the lower the community's
desire for cash. The reason is, if the level goes up,
the cost of holding money opportunitty Breadfruit is
smaller. Conversely, the lower the interest rate, the
greater the desire of society to hold cash (Nopirin,
2007:117).
Reflection-Flemming is an economic model
which IS-LM framework in a small open economy,
which can also be used to analyze the effect of
monetary policy on the exchange rate (Flemming,
1962, and reflection, 1962). IS-LM model and
reflection-Flemming assume that price level is fixed
and shows what causes fluctuations in the short term
for the combined. (Medyawati Yunanto, 2011).
3 RESEARCH METHOD
The research adopted annual data covering the
period 1993-2017 from the National Bureau
Statistics (BPS) and the Central Bank of Indonesia
(BI). Processing of collected data is done using
statistical program packages, such as Microsoft
Excel and Eviews 9.0.
The estimation model used in this study is Two
Stage Least Square (2SLS). The model in research is
the demand for money in the form of exponential
functions (Manurung J and A .H, 2009: 223)
and Mindell Fleming money offerings.

It is known that the value of Rt = rt + πt where rt
is the real interest rate and substitution of the
nominal interest rate (Rt) with rt + πt will change the
