he Threat of Cross-Sea Understanding Drones to State Defense Systems

The phenomenon of underwater drones crossing national borders may be something that is hot to discuss, this is based on the discovery of an underwater drone belonging to China by fishermen near the island of Selayar. This incident suddenly caused a stir in the community because the function of the drone itself is usually to find and record information, activities and events as well as for reconnaissance functions. The phenomenon of the discovery of foreign-owned underwater drones has not only happened once or twice, but has been found several times in Indonesian waters in recent years. So, is the phenomenon of underwater drones crossing the Indonesian border that can interfere and become a threat to the national defence system? With a qualitative research approach that uses the case study method, it is hoped that later it can produce an answer to these problems. This study uses a threat theory approach and a state defence system to be able to find out whether underwater drones are really a real threat and can disrupt the national defence system. The results of this study are that underwater drones can become a threat and disrupt the national defence system if the drone crosses national borders (enters the territory of the Indonesian state) without permission. The threat of underwater drones crossing Indonesia's maritime boundaries can be a threat because of the work of the drones themselves that can be used to spy and transmit data in real time to the control centre
