Abstract

Automatic Dependent Surveillance-Broadcast (ADS-B) allows real-time monitoring of aircraft positions, but Software Defined Radio (SDR) devices such as the RTL-SDR have sensitivity limitations that can affect signal reception quality, especially at long distances or under less than ideal  conditions. This study designs an ADS-B receiver system based on the RTL-SDR equipped with a Low Noise Amplifier (LNA) to amplify weak signals without adding significant noise. The method includes receiver circuit design, antenna installation, LNA integration, and signal reception testing at various distances. Reception data with and without the LNA are compared based on the maximum distance and the number of messages received. The results show that the LNA increases the maximum reception distance from 309.95 km to 417.90 km and improves signal stability at medium and short distances. This system is able to capture more messages, including from aircraft under less than  ideal  propagation  conditions. The combination of the RTL-SDR and LNA has proven to be effective and economical as an alternative to expensive device-based flight monitoring.

Abstract

The rapid development of information and communication technology has increased the demand for fast and reliable internet access, especially in rural areas. However, Koto Gunung Village, Batang Kapas District, Pesisir Selatan Regency, still experiences limited and unstable internet connectivity. Therefore, this research aims to design a Fiber To The Home (FTTH) network based on Gigabit Passive Optical Network (GPON) technology to provide stable and high-quality internet services for the community. The research method used in this study is the Network Development Life Cycle (NDLC), which includes literature study, field survey, network route design using Google Earth Pro and AutoCAD, and network simulation using OptiSystem software. The network performance was analyzed based on attenuation, link power budget, rise time budget, and Bit Error Rate (BER) parameters. The results showed that the total attenuation values for distribution route 1 and route 2 were 23.8216 dB and 23.874 dB, respectively, which are still below the maximum allowable standard of 28 dB. The total rise time values obtained were 0.2636 ns and 0.264 ns, which also meet the maximum standard of 0.29 ns. In addition, the simulation results showed BER values of 1.42 × 10⁻¹⁹ and 2.322 × 10⁻¹⁹, indicating excellent transmission quality with very low error rates. Based on these results, the designed GPON-based FTTH network is considered feasible for implementation in Koto Gunung Village.
