5.3 Mudharabah investment account
(X
3
) toward corporate governance
disclosure (Y)
Based on table III seen that mudharabah investment
account variables has a significant effect on corporate
governance disclosure. Effect of mudaraba
investment accounts to corporate governance
disclosure have a positive effect, that mean the higher
the investment mudaraba accounts represented by the
ratio of investment to the equity account, then the
higher the disclosures made by the Islamic bank. The
results of this research in line with Al-Baluchi (2006)
whose found that there is a positive relationship
between the proportion of investment account with a
voluntary disclosure. The relationship becomes an
opportunity for Islamic banks to increase investment
mudaraba accounts by doing more extensive
disclosures (Wan Abdullah, 2013).
5.4 Size of the islamic bank (X
4
) toward
corporate governance disclosure
(Y)
Based on table III seen that the variable size of the
islamic bank has no significant effect on corporate
governance disclosure. The results of this research in
line with Wan Abdullah (2013) whose found that the
size banks have no influence on corporate governance
disclosure. However, these results are not in line with
Ahmed and Courtis (1999) who found no evidence of
a positive effect of disclosure of the size of the
company. Further, Sharma (2012) found that there is
a positive relationship between firm size and
governance disclosure. In line with Farook and farooq
(2013) who found that there is a positive relationship
between size with voluntary disclosure. Companies
with large scale would be more likely to disclose
information widely.
6 CONCLUSION
Based on the results of research, corporate
governance strength, shariah supervisory board
strength, mudharabah investment account and size of
the islamic bank simultaneously have a significant
influence on corporate governance disclosure.
Corporate governance strength and mudharabah
investment account partially has a positive significant
effect toward corporate governance disclosure, and
sharia supervisory board strength has a negative
effect toward corporate governance disclosure,
however size of the Islamic Bank has no influence
toward corporate governance disclosure.
Referring to the results of research, average
corporate governance disclosure index Syariah Bank
in Indonesia which is 70% included in the category
enough and Bank Syariah could still improve
corporate governance disclosure index. Bank Syariah
has unique characteristics, the high level of
transparency of corporate disclosure disclosure is an
important thing in improving stakeholder confidence
against sharia compliance at Islamic Bank.
