Abstract

Perkembangan pesawat tanpa awak atau yang lebih banyak dikenal sebagai Drone kini sangat pesat. Pada wilayah tertentu, drone bisa menjadi suatu potensi ancaman privasi ataupun keamanan, karena memungkinkan untuk mengambil gambar atau informasi tanpa ijin, melakukan sabotase bahkan pengeboman. Salah satu solusi mengatasi potensi ancaman itu adalah menggunakan drone jammer. Drone jammer yang dibuat mempunyai fitur pengendalian daya pancar sinyal berdasarkan jarak sasaran. Sistem drone jammer menggunakan transmitter Devo 7E dan transceiver NRF24L01 untuk mentransmisi sinyal pada pita frekuensi 2,4 GHz. Pengukuran jarak sasaran memanfaatkan sensor ultrasonik HC-SR04. Data jarak disampaikan ke mikrokontroler Arduino Uno untuk pengaturan besar pancaran sinyal pengacau yang akan dikeluarkan oleh PGA ADL5330. Sinyal jamming akan ditransmisikan melalui antena Yagi dengan daya pancar yang disesuaikan. Hasil percobaan menunjukkan bahwa pengukuran jarak dengan sensor ultrasonik dapat mengukur jarak target hingga 375 sentimeter. Daya pemancar bisa berubah sesuai dengan jarak target sehingga daya tahan baterai bisa bertahan lebih lama. Pada jarak dekat, baterai bertahan selama 525 menit, sedangkan pada jarak yang jauh adalah 410 menit. Sinyal yang ditransmisikan oleh drone jammer adalah sekitar 3 dBm yang lebih tinggi daripada pemancar drone -30 dBm. Sistem drone jammer kurang efektif disebabkan oleh frekuensi yang terganggu hanya pada frekuensi 2,474 GHz dari 3 frekuensi yang dipakai transmitter drone, serta antena Yagi yang memiliki nilai VSWR yang buruk sebesar 5,420. Dari hasil tersebut, perlu dilakukan penelitian lebih lanjut mengenai sistem drone jammer. ========================================================================================== The development of unmanned aerial vehicle or more widely known as Drone is now very rapid. In some areas, drones can be a potential privacy or security threat, as it is possible to take pictures or information without permission, sabotage and even bombardment. One solution to overcome the potential threat is to use a drone jammer. In this study has designed and constructed a drone jammer with a feature of controlling the transmit signal power based on target distance. The drone jammer system uses the Devo 7E transmitter and NRF24L01 transceiver to transmit signals in the 2.4 GHz frequency band. Target distance measurements utilize ultrasonic sensor HC-SR04. The distance data is conveyed to the Arduino Uno microcontroller for setting a magnitude transmit power of the PGA ADL5330. The jamming signal will be transmitted via Yagi antenna with adjustable transmit power. The experimental results shows that the distance measurement with the ultrasonic sensor can measure a target distance up to 375 centimeters. Transmitter power can be changed according to the target distance so that the battery life time can last longer. At the short distance, the battery lasts for 525 minutes, while at the long distance is 410 minutes. The signal transmitted by drone jammer is about 3 dBm which is higher than the drone transmitter of -30 dBm. The less effective drone jammer system is caused by the three frequencies of the drone transmitter being interrupted only at the frequency of 2.474 GHz, and the Yagi antenna which has a poor VSWR value of 5.420. From these results, it is necessary to do further research on the drone jammer system.
