Abstract
Radar technology at several airports is still using flightradar24 as a source of information, and building an ADS-B station is expensive. However, the flightradar24 has several weaknesses, among which is that if the user wants to display more information, the user is required to pay periodically or subscriptions, and there is delay due to the process of data that requires the Internet connection. With a concept of receiver ads-b based RTL-SDR R820T2, a low cost receiver ads-b with the results can receive an ads-b signal without delay and can receive data from an airplane. But there is a weakness in rtl-b receivers based RTL-SDR R820T2, because it doesn't explain and can't know how far the receiver can receive signals and target parameters data from the aircraft. Thus on this research a receiver ads-b using RTL-SDR R820T2, with a low-noise amplification and an ads-b antenna 1090 MHZ in the hopes of knowing how far the aircraft's target range is from the receiver and knowing how far the receiver's range of data signals the target parameters. By performing some step-by-step testing of the design. The designed receiver ads-b USES low noise amplification with an ads-b antenna 1090 MHZ capable of receiving data and target parameters ads-b for 284 km on adsbSCOP software range and 287.63 km mathematically.

Summary
Teknologi radar merupakan teknologi yang digunakan untuk mendeteksi pesawat, salah satunya digunakan hampir di setiap bandar udara. Namun seiring berjalanya waktu dan kemajuan teknologi radar mulai digantikan dengan sistem Automatic Dependant Surveilance Broadcast (ADS-B) karena pada teknologi radar tersebut mempunyai keterbatasan yaitu radar tidak dapat mendeteksi pesawat yang terhalang oleh awan yang tebal. Namun untuk menggantikan fungsi teknologi radar di beberapa bandara udara masih menggunakan situs Flightradar sebagai sumber informasinya karena untuk membangun sebuah stasiun ADS-B membutuhkan biaya yang mahal. Peneliti merancang sebuah receiver ADS-B menggunakan RTL-SDR R820T2 guna meningkatkan pelayanan navigasi penerbangan di Bandar Udara Internasional Lombok. Namun dalam penelitian tersebut peneliti tidak menjelaskan seberapa jauh receiver ADS-B menggunakan RTL-SDR R820T2 dapat menerima sinyal ADS-B dari pesawat [4]. Dengan harapan hasil penelitian ini nantinya bisa diketahui dan dibandingkan seberapa jauh jarak jangkauan receiver ADS-B tersebut dapat menerima sinyal dan data parameter target ADS-B yang dipancarkan oleh pesawat
