Elaboration of Government Regulation Number 18 of 2016 on Regional Devices hasn?t been fully set forth in the Regional Regulation Number 6 of 2016 concerning the Establishment and Organization Structure of the Provincial Devices of West Sulawesi Province, especially in the guidance of determining the size/type of a regional device, which is also incompatible with Hierarchy of Legislation Theory proposed by Hans Kelsen. The Provincial Government of West Sulawesi doesn?t fully follow the guidelines contained in Government Regulation Number 18 of 2016 on Regional Devices, due to the absence of confirmation in such arrangements that prohibits any Provincial and District/City Governments to determine the size of their regional apparatus based on recommendations issued by the Ministry of Home Affairs The Republic of Indonesia, and from the results of interviews conducted and has been described in the results of research that the determination of the scale had previously been coordinated with the Directorate General of Regional Autonomy Development Ministry of Home Affairs, so that the enactment of Regional Regulation Number 6 of 2016 on the Establishment and Organizational Structure of the Regional Government of Sulawesi West can be done. There are several factors that obstruct the overall description of the guidelines in Government Regulation Number 18 of 2016 on Regional Devices into Regional Regulation Number 6 of 2016 on the Establishment and Composition of Regional Devices of West Sulawesi Province namely Legal Factors, Facilities and Infrastructure Factors, and Cultural Factors.
