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
