company as collateral for the cooperation to be 
returned if the agreement expires. Workers are also 
required to pay a fine of Rp 6 million (six million 
rupiahs) and are required to return all compensation 
received if they cancel the agreement by resigning 
before the term of the agreement expires 
The practice of detention this degree certificate 
also occurs in Banten. Many retailers in Serang City 
allegedly do the practice of detention of degree 
certificate. They hold the worker's degree certificate 
as one of the conditions of employment. They argue 
as a guarantee when something bad happens. 
Generally, this practice is mostly done by retail 
companies. Not only in Serang City, this practice is 
also suspected to occur in other cities in Indonesia. 
The findings were submitted by Commission II of 
Serang City DPRD (Regional People's 
Representative Assembly). 
The detention of degree certificate certainly 
benefits the interests of the employer as an 
employer. In the context of the agreement, the issue 
is whether the custodial certificate is an act of 
obligation in the Civil Code which may occur if a 
party denies the content of the agreement. 
The working contract is the most important legal 
basis of employment. It can serve as a protection of 
interest, juridical grip and legal certainty for the 
Employee as well as the Proponent. (Koko Kosidin, 
1999) Besides, it is also the initial juridical guidance 
and also the final juridical reference of the legal 
subjects involved in it if there will be a dispute 
within the execution of work (Lanny Ramli, 2001). 
The purpose of the contract is to regulate the 
legal relationship and give born to a set of rights and 
obligations. The agreement proves that the legal 
relationship of the parties is a legal fact. Work 
relationships are the activities of mobilization of 
personnel/services a person regularly for the benefit 
of others who govern (employers/employers) by an 
agreement that has been agreed (Hartono, 
Judiantoro, 1992 
The working contract must be made in writing. 
This is because some forms of labor agreements 
exclude the principle of consensuality, namely a 
treaty required by employment law must be held in 
writing (Hidayat Muharam, 2006). The Law of the 
Republic of Indonesia Number 13 of 2003 about 
Labor stipulates the working agreement and Article 
51 paragraph (2) of Labor Law require that the 
employment agreement is made in writing and 
executed by applicable laws and regulations. 
According to the article, if in the working 
contract made a rule that is not appropriate or not 
regulated in the applicable laws and regulations then 
the rules in the working contract need to be studied 
further. The issue of detention of degree certificate 
in the relation of working contract between the 
Employer and the Employee has not been regulated 
in Law number 13 of 2013 so that the problem of 
detention of degree certificate can be briefly 
assumed to be contradictory to Article 51 paragraph 
(2) of Law number 13 of 2013. 
Other issues in the detention of this degree 
certificate are the requirement of detention of the 
degree certificate is not specified in the employment 
contract. If included then the next problem is the 
working contract is generally in the form of a 
standard contract that is only made unilaterally so 
that no opportunity for workers to negotiate in the 
standard work contract. Standard contracts are made 
wherever possible to optimize contracts, especially 
those that focus on the company's interests 
(Christina Maria Vogerl, 2007). 
If within the period of the employment contract 
the worker in the bond is uncomfortable in 
performing his / her work, surely the detention of 
this degree certificate may be categorized as the 
implementation of the principle of freedom of 
contract which exceeds the limit to violate the 
human rights of the Employee. The Government 
itself regulates such human rights provisions in the 
provisions of public law. So it can be seen that in 
labor law there is a conflict between public law and 
private law. On one side of the contract should be 
implemented as the implementation of the principle 
of pactasuntservanda, but on the other hand, the 
government must also guarantee the rights of 
workers by the provisions of human rights 
enforcement. 
Human rights are the rights that are owned by all 
people at all times and in all places because human 
beings are born as human beings. These rights 
include the right to life, freedom and wealth as 
proposed by John Locke. Recognition is not required 
for human rights, either from the government or a 
legal system, because human rights are universal. 
For this reason, the source of human rights comes 
solely from humans. (Todung Mulya Lubis, 1993). 
This universal freedom of human rights applies to all 
human rights including workers' rights. 
The heterogeneous and autonomous law is the 
result of public and civil law aspects of employment 
relations. Thus the labor law can be said to be dual, 
on the one hand, is a public law, and on the one hand 
is also the nature of civil law. Half people say labor 
law is no longer privaatrechtelijk (civil matter), but 
publiekrechtelijk (public law) (Imam Supomo, 
2003).
