2  THEORETICAL FRAMEWORK 
According to  (Maisur, et al., 2015) the principle of 
profit  sharing  is  the  profit  obtained  by  sharia-
compliant banks that are shared with customers. The 
level  of  division  must  be  based  on  the  percentage 
ratio and not the specified amount. 
Interest  is  additional  money  deposited  in 
financial  institutions  or  money  lent.  The  amount  of 
interest  to  be  paid  is  set  in  advance  regardless  of 
whether  the  financial  institution  of  the  deposit 
recipient  or  the  borrower  is  successful  in  his 
business or not. The amount of interest that must be 
paid is listed as a percentage number or per hundred 
in a year which means that if money is not paid or 
deposits are not taken in a few years the debt can 
occur  or  the  savings  will  multiply    (Muhammad, 
2011) 
The  issue  of  interest  responsiveness  to  savings 
and  its  effect  on  economic  growth  in  developing 
countries (LDCs) concluded that the high interest of 
the people in saving was influenced by the high and 
low interest rates. The higher  interest rate results in 
an increase in the amount of savings. If the interest 
rate is high, then the community will reduce current 
consumption to increase savings  (Arrieta, 1988). 
Financing  projects  are  at  the  core  of  people's 
lives  and  development  bases.  Funding  patterns, 
instruments and frameworks facilitate financing and 
lead  to  development.  Several  types  of  financing 
instruments are common in developed countries that 
lubricate  the  wheels  of  development.  Islam  forbids 
flowers  and  justifies  profit  sharing.  Both  provide 
benefits but have fundamental differences as a result 
of  investment  and  money  saving    (Maisur,  et  al., 
2015). 
In  conducting  transactions  in  Islamic  banks, 
customers  only  consider  the  profit  sharing  factor. 
When  it  is  found  that  the  profit  sharing  rate  of 
Islamic  banks  is  higher  than  the  interest  rate  of 
conventional  banks,  such  as  when  the  research  is 
conducted, they will join Islamic banks. The rest, if 
the situation is reversed, it is feared they will choose 
to  join  a  conventional  bank.  From  here  a  simple 
prediction  can  be  made  if  the  interest  rate  is  high 
while  the  profit  sharing  rate  is  unable  to  keep  pace 
with the rate of interest, it is not impossible if the 
customer will transfer  funds to a  conventional bank 
which offers higher economic benefits  (Misanam & 
Liana, 2007). 
The policy carried out by the company to achieve 
reputation is by holding a personal selling, because it 
is  considered  that  this  program  can  be  closer  to 
themselves  between  companies  and  consumers 
(Azis,  2001).  Several  things  related  to  this  are  that 
personal selling must take place through face to face 
with  customers  and  must  be  aggressive  in  order  to 
provide  communication  between  customers  and 
companies that will provide a form of service  (Azis, 
2001). 
The  company's  reputation  is  built  on  a  network 
of  stakeholder  partnerships  through  which 
companies  continue  to  improve  organizational 
learning  and  develop  new  business  solutions.  In 
particular,  the  activation  of  decision  processes  that 
involve  stakeholders,  partnership  building,  and 
supportive behavioral stimulation, allows companies 
to recover from severe losses of investor confidence  
(Romenti, 2010). 
Even  though  the  company's  reputation  is 
everywhere,  it  is  still  relatively  replaceable.  Some, 
surely because reputation is rarely noticed until they 
are  threatened.  Economists  see  reputation  as  a 
transitory  signal.  Game  theory  describes  reputation 
as  a  character  that  distinguishes  between  types  of 
companies  and  can  explain  their  strategic  behavior. 
Signaling  Theory  calls  our  attention  to  the 
information  content  of  reputation.  Both  recognize 
that  reputation  is  actually  the  perception  of  the 
company  that  is  owned  by  external  observers.  For 
Game Theory experts, reputation is functional: they 
generate  perceptions  among  employees,  customers, 
investors,  competitors, and  the general  public about 
what a company is, what it does, what it means. This 
perception  stabilizes  the  interaction  between  the 
company and its people  (Fombrun & Riel, 1997). 
Past  behavior,  attitudes  and  product  attributes 
together  have  a  significant  effect  on  interest  in 
saving  (Sagan, et al., 2012). Examined the effect of 
service  facilities,  products  and  promotions  on 
customer  decisions  in  saving  where  the  factors  of 
service  facilities,  products  and  promotions  have  an 
influence on  customer  decisions in saving   (Yupitri 
& Sari, 2012). 
Disclosure  of  information  to  bank  stakeholders, 
should not be limited to financial information alone, 
but  also  non-financial  information  that  allows 
customers  to  know  the  level  of  suitability  of  bank 
operations with the principles that exist in the bank. 
This  is  because  with  the  existence  of  complete 
reporting  of  information  it  will  support  the 
relationship  of  corporate  governance  that  is 
beneficial for both parties  (Yulianto, 2010). 
The  desire  of  customers  to  obtain  financial 
information  as  complete  as  possible  is  difficult  to 
fulfill  by  management  because  it  is  influenced  by 
several  factors  such  as  the  cost  of  presenting 
information,  management's  desire  to  avoid  risks  to 
see  its  weaknesses,  and  time  used  to  present 
information    (Yaya  &  Ahim  Abdurahim,  2003). 
Besides  this  according  to    (Yaya,  et  al.,  2007) 
management needs  to  consider  cost  and  benefits  in 
presenting  disclosure  in  financial  reports  or  annual
