3  RESULT AND DISCUSSION 
3.1  The Framework of Law on Special 
Economic Zone in Indonesia 
According to the World Bank, Special Economic 
Zone is made out of, an area that is geographically 
restricted with a separated area of customs, under the 
supervision of the administrator, and that the benefits 
may be felt by those who lived inside the zone itself. 
In other words, Special Economic Zone is a zone 
where the government was expecting to raise the 
economic growth through the increasing of exports 
and investments also providing various competitive 
advantage for the entity who chose to locate within 
the zone (Rizal, 2015).
 
That definition is relevant to 
the regulation under Article 1 point (1) of the Law No. 
39 of 2009 defines a Special Economic Zone as a 
specially regulated zone that is located within the 
jurisdiction of The Republic Of Indonesia which is set 
to carry out an economical function and to receive 
certain facilities. 
The Politics of Law that that underlines the 
existence of Special Economic Zone is to attract the 
interest of investors to conduct a direct investment 
which promises a number of regulatory exclusivities, 
the ease of service and fiscal facility inside Special 
Economic Zone. Therefore, the enforcement of 
investment services in Special Economic Zone was 
released from the government bureaucratic networks 
that forms their own institution on managing the 
Special Economic Zone. According to Law No. 
39/2009 this institution consists of: National Council, 
District Council, and District Administrator. Through 
the structure of One Stop Service (PTSP), District 
Administrator plays a very strategic role in operating 
stages. This institution received an abundance of 
authority from all of the ministry regarding the non-
department government institution, provincial and 
regency/city government. With this method, a long 
bureaucratic networking will be abolished owing to 
the fact that all relating affairs regarding investments 
inside the Special Economic Zone falls into the 
authority of District Administrator. And of course, 
this is expected to be an attracting factor owing to the 
fact that this will reduce the transaction cost for the 
investor. 
To support the enforcement of Special Economic 
Zone, the Indonesian Government has created a 
number of constitutions. No less than 50 constitutions 
have been made, from Law up until Government 
Ordinance has been created to support the Special 
Economic Zone. Furthermore, Regional Regulation 
which is a law created by province and regency/city
