**5. Achieving consensus to diminish natural coastal conflict management through marine spatial planning**

Sea and coastal areas are locations that have enormous potential that can contribute greatly to the national economy. The potential of marine and coastal areas include the potential of fisheries, the potential of environmental services, the potential of marine energy, and the potential of mining. This potential must be managed well in an integrated and sustainable manner. Good management requires a well-structured plan that takes into account geographical conditions and the sustainability of the plan in the future.

Preparation of marine spatial plans and small islands is a crucial point to achieve optimal management of marine and coastal areas. An integrated spatial plan between land and sea, which does not only consider ecological and environmental

aspects, should also be implemented in the planned area, in accordance with Law No. 26 of 2007 concerning Spatial Planning and Law No. 1 of 2014 concerning Management of Coastal Areas and Small Islands.

Environmental balance aspects that will be influenced by the physical construction activities in the sea and coastal areas need a study in the activities of the preparation of the intended spatial plan, so that activities can run in a harmonious and sustainable manner. Thus the spatial planning for the sea and coastal areas to be compiled should implement an integrated spatial plan between the sea area and its land area as well as accommodate the aspirations of the community from the planning and utilization to control processes.

Marine spatial planning has a crucial policy for solving spatial use conflicts, namely, by identifying and mapping all uses, regulations, and conflicts that occur [7]. Initially, conflicts occurred in the ecological aspects, then toward social conflict, and finally toward economic conflict [8, 9]. The conflict mapping is a technique used to describe graphically, connecting parties to problems and with other parties. One method of mapping this conflict under open spatial data context is a participatory mapping from local coastal communities.
