Abstract
UAV atau Drone telah menjadi alat yang banyak digunakan baik oleh militer maupun masyarakat umum. Hal ini dikarenakan fleksibilitas dan bisa digunakan dalam situasi apapun serta bisa dikendalikan pada jarak yang jauh. Namun, terdapat potensi kejahatan yang bisa terjadi. Oleh sebab itu, sistem anti drone perlu untuk dibuat agar keamanan dan privasi suatu tempat dapat ditingkatkan. Untuk dapat melakukan gangguan terhadap sinyal drone, maka digunakan metode jamming dimana metode ini merupakan metode yang simpel dan dapat diaplikasikan pada drone yang tidak dikenali. Pada penelitian ini digunakan frekuensi 2.4 GHz yang juga merupakan frekuensi yang sering digunakan pada drone. Pada penelitian kali ini akan digunakan metode Spot Jamming mengingat frekuensi ini hanya menggunakan bandwidth sebesar 20 MHz sehingga kita akan dapat melakukan variasi bandwidth. Pada percobaanya dilakukan berbagai kondisi untuk dapat melihat bagaimana efek gangguan sinyal jamming. Pada penelitian ini digunakan Software Defined Radio sebagai perangkat untuk dapat membangkitkan sinyal. Nilai perbandingan daya total minimum antara sinyal jamming yang dihasilkan dengan sinyal drone yang digunakan yang diperlukan agar sinyal jamming dapat mengganggu drone adalah harus melebihi 1. Percobaan menghasilkan daya yang dihasilkan hanya dapat mengganggu pada jarak maksimal sebesar 1 meter. Untuk dapat melakukan gangguan pada jarak jauh diperlukan gain tambahan sebesar 122.55 dB untuk jarak sebesar 50 meter dan gain sebesar 137.8 dB untuk jarak 100 meter.

Unmanned Aerial Vehicles (UAVs) or drones have become widely used tools, both by the military and by the general public. This is due to their flexibility, ability to operate in various situations, and capability to be controlled over long distances. However, there are potential criminal threats associated with their use. Therefore, anti-drone systems need to be developed to enhance the security and privacy of certain areas. To interfere with drone signals, jamming methods can be employed. Jamming is a simple technique that can be applied to unidentified drones. In this study, a frequency of 2.4 GHz is used, which is also a common frequency utilized by drones. The Spot Jamming method is implemented in this research, considering that this frequency only uses a bandwidth of 20 MHz, allowing for bandwidth variation. Various experimental conditions were carried out to observe the effects of jamming signal interference. Software Defined Radio (SDR) was used in this study as the device to generate the jamming signals. The minimum total power ratio between the jamming signal and the drone signal required to successfully interfere with the drone must exceed 1. The experiments showed that the generated jamming signal could only interfere with the drone at a maximum distance of 1 meter. To perform jamming at greater distances, additional gain is required, specifically 122.55 dB for a distance of 50 meters and 137.8 dB for a distance of 100 meters.
