Interaction of the both causes a conflict of interest and will also affect the ecosystem and social system. The spatial plan needs to be regulated as an institution to achieve the spatial orderly. Based on these problems, the purpose of this study was to obtain structural institutional models in the implementation of spatial regulations. Data obtained by depth interviews in 75 (seventy five) interviewees. Data processed by the methods of ISM (Interpretive Structural Model). The conclusions of this research are: (i) the regulation direction which is the task of the government in spatial planning must consider the welfare of the people, the human right, and indigenous peoples rights as outlined in the form of spatial structure plan, spatial pattern plan, and the establishment of strategic areas. Spatial planning will go well in the event orderly. Orderly space will be achieved when people pay attention to the direction of zoning, the direction of licensing, intensive disincentives, the direction of sanctions, minimum service standards and monitoring procedures. (ii) The control and supervision of a government authority that is guided by the spatial structure plan, spatial pattern plan, and the determination of strategic areas as outlined in the form national spatial planning, wich in details contained in the main indication of the development program, land uses, water control, air uses, and spatial planning provincial strtegic areas. (iii) The position of the government in spatial planning, in accordance goverment of the structure beginning with spatial of national planning and thereafter in accordance with the following order: long- term development plan/annual, spatial plans (regency/city), reference of the traditional village, the main indication of the development program, land uses, water control, air uses, and spatial planning provincial strtegic areas. Keywords: Institutional structures, spatial plan, spatial utilization, spatial control 1. Introduction In the organization of spatial planning involves two important components. The two components are: (i) earth (nature), as a region or area that can not be separated from ecosystem problems that include functional units of interaction between plants, animals and the natural surroundings; and (ii) human beings, who basically can not live alone, but live in groups, which can not be separated from social system problems as a result of human interaction. The social system is divided into four subsystems, such as Parsons (in Sutami, 1977: 12), so that a person can serve as economic beings, beings political, social beings, and human culture. Muslion (2008), explains that at the core of national development planning documents is a development plan compiled in an integrated manner by ministry/agencies and development planning by local governments in accordance with their authority. According to Law No. 26 of 2007 (2007: 1), which in consider that the regional autonomy policy giving greater authority to regional governments in the implementation of spatial planning. The local authorities need to be regulated in order to maintain harmony and cohesion between regions and between the central government and local governments. This is why the importance of institutions as a rule within the framework of spatial planning, so as not to cause regional disparities are primarily related to the development of the region. An institutional role within the community includes regulations that establish the community in conducting interaction. Space is limited environmental components and cannot be refurbished and must be utilized optimally and sustainably. Implementation of spatial planning is an effort to achieve goals through spatial planning, space utilization, and control of space utilization. In the implementation of spatial arrangement involves two
