can be carried out by means of supervision (built in 
control), improvement of the supervision system and 
strengthening regulations through the application of 
the precautionary principle, establishing a financial 
safety net (financial safety net), stabilizing the 
banking system that directs the bank to good practices 
corporate governance and the fulfillment of the 
principle of prudence, professionalism of the 
apparatus continues to be improved so that it has high 
integrity capabilities, has sufficient competence, and 
has a good financial reputation or non-juridical 
measures in the form of public opinion actions and 
socialization of the community. 
Lewerissa (2013) states specifically, law 
enforcement and prevention of banking crimes can be 
pursued through: 
1.  It is necessary to increase the ability of 
investigators in the field of accounting and 
finance. 
2.  An effective bank supervision system and this 
can be done if employee recruitment 
emphasizes more on mental ideology. 
3.  Expansion of the authority of investigators in 
the context of carrying out their duties, not just 
concerning bank secrets. 
4.  Renewal of laws in the economic field in casu 
banking law. 
Majority observations indicate that some 
businesses are in the process of becoming 
professions, some professions that take on some 
business characteristics, and other jobs that are 
appropriate and have even been firmly included in 
business and professional roles. 
These two conflicting roles are likely to create a 
conflict of interest, which in turn can lead to a 
deviation and violation of the rules. If a profession on 
one side then doubles with a job that does not support 
the profession, even if it crosses business alone, then 
usually there will be a violation, because there are 
multiple roles that conflict with each other. This 
creates a conflict of interest. 
Delegation of work roles is a common 
phenomenon in modern society, partly because of the 
frequency and speed with which changes in the 
definition of work roles occur and new job roles 
emerge. In particular, it seems clear that the role of 
business and professional work. 
5 CONCLUSION 
The bankers in carrying out their profession have 
operational guidelines, both in the form of formal 
provisions, and ethics which are conduct norms. In 
carrying out there are two roles that he lived. It 
depends on how bankers can position themselves 
when acting as bankers and not as bankers. When 
they cannot play the two roles properly, there will be 
a role conflict that can lead to violations. However, if 
they can portray correctly, when as a banker and 
when as a non-banker, then this banker is not the 
violator. For this reason, it is necessary to understand 
by bankers, so that in carrying out these dual roles, 
they can truly be carried out in accordance with their 
conditions, both as bankers and as employees. And 
this is followed by making a good control mechanism 
continuously and consistently.
