Territorial sovereignty is the sovereignty of a state when exercising exclusive
jurisdiction over its territory. The territory of a country is divided into three, namely
land, sea and air. To obtain full sovereignty, all parts of the territory must be
claimed. Indonesia is an archipelagic country that has many islands. The territorial
area owned by Indonesia is quite large. However, not all of the islands in Indonesia
are owned exclusively by Indonesia due to an agreement between the Indonesian
Flight Information Region and Singapore which regulates the authority to carry out
air control around the islands of Riau and Natuna. On January 21, Indonesia and
Singapore agreed to make adjustments to airspace services or the Flight Information
Region, which regulates so that Indonesia can take back control of the airspace
around the islands of Riau and Natuna. However, after the holding of the Flight
Information Region agreement between Indonesia and Singapore, the agreement was
not in accordance with the mandate of Law Number 1 of 2009 concerning aviation.
The non-fulfillment of the mandate of the law results in the non-fulfillment of the full
and exclusive airspace sovereignty in Indonesia.
