The Indonesian Navy is a unit of defense of the Republic of Indonesia (NKRI). Sea mines are explosive devices placed in waters to destroy ships. Acoustics is a branch of physics that deals with all mechanical waves in liquids, gases and solids, such as vibration, sound and ultrasonic. Arduino has made microcontroller technology more accessible and easier for even novice users. Because of this, there are special functions in audio or acoustic processing techniques aimed at using Arduino. The application of acoustic signals in the military field of the Navy, in the identification of vessels caught by the microphone receiver. The movement of objects that are caught by the microphone will be analyzed to conclude the object. From the results of the sound characteristics raised by the object, it will give a different picture for different variations of the object. Processing acoustic signals using DSP will make it easier to infer the captured acoustic signal. The circuit board used is a microphone signal amplifier and signal conditioner, for processing the audio signal obtained from the microphone and to produce output data which is the result of the process using Arduino. Analog-to-digital converter (ADC) of the microcontroller works in the voltage range from 0.0 V to +3.3 V or +5.0 V. Toachieve good sampling results, that the signal peak is close to the maximum value of the ADC. Additionally, voltage amplitudes above this threshold can damage the controller input port or produce unwanted harmonics. Therefore, a signal pre-amp circuit is needed to guarantee the appropriate audio sample signal as well as to protect the system. The test results obtained from the system analyzer frequency and signal meters can be used to identify acoustic signals.

Based on Law No. 34 of 2004, the Indonesian Navy has the main task of maintaining state sovereignty in territorial waters. Various attempts have been made to strengthen the Navy so that it can carry out these basic tasks, one of which is to add defense equipment, namely ships that have the ability to shoot missiles. This missile possession is important because in addition to being a deterence effect, modern naval battles are dominated by long-distance warfare or Over The Horizon. In missile fire, accurate intelligence is needed to determine the position of the target. So far what has been done is sending submarines or reconnaissance aircraft. This is very inefficient because in addition to requiring large resources, the risk of losing personnel and material is also very large. Based on this, the researcher makes a prototype of a vehicle that can identify and determine the position of a target. The vehicle in the form of a UAV is equipped with GPS, altimeter, compass and camera. This equipment will provide data in the form of UAV latitude and longitude position, UAV height, UAV heading and UAV camera angle. From the four data above, the ground station on themissile carrier gets the target's latitude and longitude data based on image processing. While the method used is color thresholding which can distinguish a target based on its color. After several trials, the UAV has been able to carry out the target positioning up to a height of 15.4 meters. At these heights the target latitude can be determined with a system accuracy of 3.3 meters. To be used as a reference for missile firing, it is necessary to increase the capability of the equipment specifications to reach the desired distance. Keywords: Target, Latitude, Longitude, Image Processing.

Good management of international relations has been a major concern of Indonesia's foreign policy since the country's independence. The character of the nation and state leaders is often the determining factor that causes relations between countries in a situation full of uncertainty. Some parties, based on the analysis of confidential documents, are allegedly trying to influence the policies of their respective countries to give recognition to Papuan independence and sovereignty. Based on Presidential Regulation No. 16 of 2017 concerning the Indonesian Maritime Policy dated February 20, 2017, Indonesia's geographical and demographic conditions will have consequences for the emergence of the real challenges for Indonesia that must be managed comprehensively. Specifically, in Papua, referring to data from the Navy of 2019, at least in the last period more than 50 (fifty) transnational crime and intrastate conflicts (communal conflicts and separatist movements) occurred in Papua. In addition to maritime defense forces, maritime diplomacy as a form of state policy has been transformed into an alternative in efforts to reduce the vulnerabilities that have arisen in the Papua region. The Navy as a military force is part of implementing the policy to realize the main program of Maritime Diplomacy, namely increasing the active role in efforts to create world peace and security. The Indonesian Navy describes the policy through the perspective of modern maritime defense policies that understand the nation's history to meet the political will aspects (maritime diplomacy) through cooperative, persuasive and coercive efforts. There are six factors that influence the implementation of the Maritime Diplomacy Policy in Papua, including: 1) Size and Policy Objectives; 2) Resources; 3) Characteristics of Implementing Agencies; 4) Communication between Implementing Agencies and Implementing Activities; 5) Disposition of Implementing Agencies; and 6) Environmental Effects. Environmental influences are the most influencing factors in implementing policies. The influence can come from inside or outside. The main internal influence comes from the longstanding conflict in Papua. External influences take the form of conventional and non-conventional threats. Keywords: Maritime, Diplomacy, Papua

Marine mines are one of the supporters in securing the marine region of NKRI. In relation to marine mines, the Navy has mapped mines to the territorial waters. The importance of mine site mapping information aims to prevent landmines from being a feeding weapon for the NAVY's Alutsista. In realizing a mine-site mapping and location system that can provide geo-location information for mines using Arduino devices. Build your exercise Smart mine positioning using Global Positioning System (GPS) Neo-M6. A study in providing latitude and longitude location information is packaged using a GPS module that is connected to the Arduino processing device to obtain the location coordinates of the latitude and longitude mines. Test results of GPS-based location tracking devices are obtained by the results of location data in latitude and longitude formats. Smart Mine location identification, can be applied using GPS based on the results of the design and creation of the system that has been done. Location displacement speed calculations can be obtained by calculating the starting location with the updated location in a time span and converting to a unit of distance. Based on the results of the speed test can be obtained even if the device's location position is unchanged, this is due to the GPS data always changing due to the level of position accuracy obtained from satellites. The use of the Neo-M6 GPS can be applied to the latitude and longitude location identification systems acquired a relatively small error value with an average satellite number obtained by as much as 8 satellites. The use of the Neo-M6 GPS, to get GPS data from satellites is a long time, the problem of GPS gets satellite data due to the less supportive weather conditions.
