PERANCANGAN SISTEM MONITORING FREKUENSI GELOMBANG RADIO DALAM MENDUKUNG TUGAS POS ANGKATAN LAUT BERBASIS MIKROKONTROLER DAN RTL - SDR

Abstract

Violation of Indonesia’s maritime borders by foreign vessels without permission is
increasing, resulting in various losses. Keeping up with the times where increasingly
sophisticated technology also helps in the development of military equipment. To
minimize the occurrence of such violations, the radio wave frequency monitoring system
equipment has the feature of being able to monitor radio waves that work at a frequency
of 100 Khz to 1.8 Ghz with the aim of obtaining information to support and increase
awareness in border areas. translated by RTL-SDR and displayed on the display on
the laptop. The selected frequency will be locked and listen to the information carried
by the radio waves using a headset. In addition, as an indicator that this tool is able to
work using the Arduino nano microcontroller as a liaison between the Arduino software
and the hardware used as an indicator that this tool is ready to operate. Microcontrollerbased radio wave frequency monitoring systems and RTL-SDR can be used to assist
the task of the Navy post in improving security and reducing the risk of violations in the
Indonesian maritime border area. The most frequent violations are foreign ships that
often enter the Indonesian sea border area without permission. From the results of the
analysis and testing of the tool that this tool is very effective in supporting the task of
the Navy post in guarding Indonesia’s maritime borders. This design will be better if it
is added with a foreign language translator feature to make it easier for operators to
process the information obtained.
