someone else. In a narrow sense, the financing used 
to define the funding committed by financial 
institutions, such as Islamic banks to customers. 
Furthermore, in the regulation of Islamic bank, 
Islamic Banking Act No. 21 of 2008, stated the 
definition of financing is the provision of funds or 
bill equivalent to the form: 
1.  Profit and Loss sharing transaction in the form of 
mudharabah and musyarakah; 
2.  Leasing transaction in the form of Ijarah or lease 
purchase in the form of Ijarah muntahiya 
bittamlik; 
3.  Sale and purchase transaction in the form of 
murabahah, salam, and istishna’; 
4.  Borrowing transaction in the form of receivables 
qardh; and 
5.  Lease services transaction in the form of Ijarah 
for multiservice transaction; 
2.3  Third Party Funds 
Third party funds are usually more familiar with 
public funds, the funds raised by banks from the 
public in the broadest sense, encompassing 
individual communities, and business entities. Bank 
offers deposit products to the public in raising funds 
(Ismail, 2010: 43). According Dendawijaya (2005: 
49), the funds collected from the community is the 
largest funding source of the most reliable bank that 
can reach 80% -90% of all funds managed by the 
bank. Banks do not give a reward in the form of 
interest on funds deposited by customers in the bank. 
The payoff is given on the basis of the principle of 
sharing (Budisantoso and Triandaru, 2006). 
2.4  Non Performing Financing 
Non performing financing is a condition in which 
the customer is no longer able to pay part or all 
liabilities to banks as it has been agreed (Kuncoro 
and Suhardjono, 2002: 462). NPF ratio reflects the 
bank's ability to cover risks of failure of loan 
repayment by the debtor (Darmawan, 2004). If not 
handled properly, then the problem of financing is a 
source of potential losses for banks. Therefore, we 
need a systematic and sustainable handling 
(Mahmoeddin, 2004: 5). NPF is very influential in 
controlling costs and at the same time also affects 
the financing policies that would do the bank itself. 
NPF can bring adverse impact, especially if the NPF 
in large quantities. By looking at previous NPF (t-1), 
the bank may consider how much funding will be 
distributed now. 
2.5  Capital Adequacy Ratio 
The capital adequacy ratio (CAR) is a measure of a 
bank's capital. It is expressed as a percentage of a 
bank's risk weighted credit exposures. The level of 
capital adequacy can be measured by comparing the 
capital with third-party funds and capital compared 
with risk assets (Arifin, 2009: 162). 
2.6  Bank Indonesia Sharia Certificates 
In order for the implementation of open market 
operations can be run properly, it is necessary to 
create a device controlling the money supply in 
accordance with the principles of Sharia in the form 
of Bank Indonesia Sharia Certificates (SBIS). The 
device can be used as a short-term fund deposits, 
especially for banks that have excess liquidity. 
Islamic banks that have idle funds, can invest their 
funds in these instruments. Bonuses obtained and the 
absence of risk factors, SBIS attractive for Islamic 
banking compared channeled through financing 
(Nurapriyani, 2009). 
2.7  Effect of Third Party Fund (DPK) 
on the distribution of Financing 
Collection and distribution of funds is the main 
focus of activities of Islamic banks. Therefore, in 
order to optimally distribute the funds, the bank 
must have the ability to raise funds for Third Party 
Fund (DPK). Because it is the major source of 
Islamic bank financing. Deposits or Third Party 
Fund (DPK) is the funds raised by banks from the 
public, both individuals and business entities that 
obtained by using various instruments deposit 
products such as wadiah  current accounts, wadiah 
saving accounts, mudharabah saving accounts, and 
mudharabah deposits accounts. 
Once the funds have been collected by a third 
party bank, then according to his function then the 
intermediary bank is obliged to distribute these 
funds back to communities in need, namely in the 
form of loans or can be referred to as financing 
(Kasmir, 2008). Funds that have been collected from 
the community is the largest funding source of the 
most reliable by banks and have a strong influence 
on the financing (Dendawijaya, 2008). 
Francisca (2008), stating that the higher DPK 
will increase financing expansion in the banking 
system. Similarly, Khatimah (2009), Nurapriyani 
(2009), Pratama (2010), and Andraeny (2011) which 
state that the higher third party funds that have been
