Implementation of Marine Cadastre for Sustainable Marine Management and Spatial Planning: A Case Study of the Bajau Tribe in Indonesia

Abstract

Marine management and spatial planning based on zoning allocation needs to be implemented considering that the sea is a place where humans live. This is supported by the presence of the Bajau Tribe in Indonesia as an indigenous community that has lived in the sea all their lives by building houses above the sea. This condition raises potential problems related to the recognition of sea property rights and legal guarantees as a form of justice and equality. For this reason, the implementation of a marine cadastre as a marine spatial planning and management system is carried out to realize the 3R principle (right, restriction, and responsibility). This concept uses the approach that the sea is a continuation of land where there is land on the seabed.

This research aims to produce a map of marine cadastre objects for Bajau Tribe Houses based on the analysis of technical and legal aspects. Identification of technical aspects succeeded in determining Mean Sea Level (MSL) as a vertical datum at a height of 60.229 meters against the ellipsoid with an accuracy of ± 0.034 meters. Supported by legal aspects, the opportunity to grant sea property rights to the Bajau Tribe's land can be carried out as a manifestation of sustainable marine management and spatial planning.
