research by Sakai and Asaoka (2003) and Premuroso 
and Bhattacharaya (2007), which concluded that the 
implementation of CG would be able to support 
companies to achieve good performance.  
This study found no significant effect of 
government ownership on bank profitability. 
Meanwhile, foreign ownership has a negative 
influence on profitability. This result shows that the 
sample of banks used in the study, the greater the 
foreign ownership has lower financial performance. 
This finding does not support the opinion that 
foreign-owned banks perform better, and banks 
owned by the government perform worse. This result 
is in line with the findings of Novado and Hartomo 
(2014). 
Regression results from the model (2) show that 
only profitability and foreign ownership have a 
significant effect on firm value. Meanwhile, CG, 
government ownership, and company size were 
unable to influence firm value significantly.  
As predicted, profitability has a significant 
positive effect on firm value. This finding confirms 
the signaling theory, which states that good 
profitability is a positive signal for the market, so 
when profitability achieved by banks improves, it will 
be reflected in an increase in its stock price. These 
results support the results of the study of Sumarno et 
al. (2016) and Makhdalena (2016). This study 
concluded that the profitability of companies has an 
important role in influencing the value of companies 
in Indonesia. 
Meanwhile, CG does not have a significant 
influence on firm value. But this influence becomes 
significant when mediated by profitability. This effect 
can be inferred from the Sobel test results (Table 5), 
which show that the Sobel test value is significant on 
the effect of RoA meditation on the influence of CG 
on PBV. These results answer the findings of 
previous studies, which found no significant effect of 
CG on firm value (Nurfaza et al., 2017). This can be 
interpreted as when the market finds that the CG 
implementation of a company is good, but 
profitability is not good, then that signal can not 
influence the market decisions. 
The results for the effect of ownership on firm 
value also show different results. The effect of 
government ownership on company value is not 
significant, while foreign ownership has a negative 
effect. These results are linear with the effect of these 
variables on profitability. Foreign ownership has a 
negative effect on profitability, as well as its effect on 
the value of the company. 
 
 
5 CONCLUSIONS 
Good governance in the bank industry is very 
important to implement. As an industry that receives 
public trust to manage their finances, banks must have 
accounting systems and procedures. Management 
guarantee from the banking industry is influenced by 
the monitoring function in the banking sector. This 
monitoring function can be seen from the ownership 
structure and corporate governance. This study aims 
to obtain evidence of whether corporate governance, 
the ownership structure of the bank industry, affects 
profitability, and corporate value. 
The results of this research show that there is a 
significant effect of CG, foreign ownership, and total 
assets on profitability. The better implementation of 
CG will have an impact on higher profitability 
achieved by the bank. However, this study does not 
found the impact of government ownership on bank 
profitability. Meanwhile, foreign ownership has a 
negative influence on profitability. This result shows 
that the sample of banks used in the study, the greater 
the foreign ownership has lower financial 
performance.  
This study also found that profitability and foreign 
ownership have a significant effect on firm value. 
Meanwhile, CG, government ownership, and 
company size were unable to influence firm value 
significantly. This study found a mediating effect of 
profitability on the effect of CG on firm value. 
This study subject to several limitations. First, the 
study only uses a proxy of profitability. Using more 
than one indicator of profitability may give different 
insights. Second, this study observes the ownership 
structure as the monitoring functions of the 
management. This variable does not impact 
significantly on firm value. Further study can develop 
other variables of monitoring function of the bank 
that may effect firm value.
