5. Hypothesis Planning Data Analysis
In doing analysis, the writer through the following steps:
a. Collecting data, which related with interrelated variables such as customer and short term funding over total assets, equity financing rate, and
profitability. Determining the value of interrelated variables match with determined formula from previous data that already collected.
b. Doing statistic testing to test hypothesis and also interpret and make analysis over the result of hypothesis testing.
c. Making summary according to the result of statistic testing.
Hypothesis determination Simultaneously:
Ho

: µ = 0 there are no significant influence happened simultaneously between
customer and short term funding over total assets and equity financing rate over Islamic bank profitability
Ha

: µ ≠ 0 there are significant influence happened simultaneously between
customer and short term funding over total assets and equity financing rate over Islamic bank profitability
Partially: 1. Customer and Short Term Funding over Total Assets

Ho

The steps on hypothesis testing in regression and correlation analysis are:
1. Normality Test Normality test is done to knowing whether or not each variable distributes
normally. 2. Multiple Regression Linear Analysis
Regression analysis is used to predict the value of variable Y based on the value of variable X and also the changing prediction on variable Y for
every changing unit of variable X. the equation form of this multiple regression linear is:
Y = α + β
1
+ β

X2 + ε
Where: Y
= Profitability Return on Assets X

Result and Discussion Customer and short term funding over total assets
is a ratio between the amount of Customer and short term funding namely the fund of member or third
party which consist with the amount of giro wadiah, mudharabah saving, and mudharabah deposit; with total assets or total a total assets owned by Bank
Syariah Mandiri.

Level of Equity Financing Mudharabah-Musyarakah Ratio
Level of equity financing or cost level of sharing profit by using proxy of Mudharabah-Musyarakah ratio MMF illustrate the amount of Mudharabah –
musyarakah cost skim or cost of sharing profit equity financing to the total of amount of cost which is given.
The component of this ratio is kind of the amount of mudharabah and musyarakah also the total amount of cost which is gained from the financial report
of Bank Syariah Mandiri. Profitability Return Assets
So profitability uses the ratio of Return On Assets ROA is kind of ratio between profit after tax or net profit with total assets total activa which is
owned by Bank Syariah Mandiri. This ratio is used to measure the ability of bank management in obtaining the profit totally through managing the asset which is
owed by bank.

So Profitability uses the ratio of Return on Assets ROA is kind of ratio between profit after tax or net profit with total assets total activa which is owned
by Bank Syariah Mandiri. This ratio is used to measure the ability of bank management in obtaining the profit totally through managing asset which is owed
by the bank.
From the early processing data which is resulted values obtained from independent variables and dependent variables of research as presented in the
table 8. the values of those variables will be processed further by using the support of software SPSS 13.0 in order to answer the identified problem.

Analysis of double linear regression From the above table 9, it is obviously can be seen that the functional
relation between customer and short term funding over total assets with return on assets ROA is in versely proportional whereas the relation between the level of
equity financing and ROA is inversely proportional. It means, every increasing which takes
place at CSTFTA will be followed the increasing of ROA bank, and every increasing the level of equity financing will be followed by the decreasing of
ROA bank and vise versa. Dependent Variable: roa

Ho for significant rate 5, it means the influence and relation between independent variables simultaneously Customer and Short Term Funding over
Total Assets and Equity Financing Rate Mudharabah – Musyarakah Ratio with dependent variables is non- significant profitability Return on Assets.
t Test
Partially testing is done to knowing the existence of relation or influence one of independent variable with dependent variable with assumption that the
other variables are constant. The test result with helps from SPSS 13.0. can be seen on the following table 12.
In testing this hypothesis, the criteria which can be used is a criteria where: Ho is accepted when: -t

Ho is rejected when: t

with df = n-k-1 = 7-2-1 = 4 then the obtained t

for Customer and Short Term Funding over Total Assets is 2.980 an for equity financing rate Mudharabah- Musyarakah Ratio is -
