Abstract

LoRa (Long Range) is a wireless communication technology that has gained significant attention in the Internet of Things (IoT) due to its wide coverage and low power consumption. However, its performance is often affected by environmental obstacles that cause signal attenuation and interference. In Indonesia, LoRa is regulated to operate in the 920–923 MHz band, whereas many commercial devices are designed for 915 MHz, leading to suboptimal antenna performance. Therefore, this research aims to design and simulate an antenna that can operate effectively across 900–923 MHz, covering both the commonly used 915 MHz band and the regulated 920–923 MHz band in Indonesia. The proposed design is a 1×2 Antipodal Vivaldi Array antenna using an FR-4 substrate with a dielectric constant of 4.3 and thickness of 1.6 mm. The simulation process was conducted using CST Studio Suite 2019, focusing on the optimization of key geometric parameters such as feedline width, inter-element spacing, flare structure, and ground plane. The simulated results show that the antenna achieves a return loss of –19.11 dB at 923 MHz, a bandwidth of 344.4 MHz, and a gain ranging from 5.103 dBi at 900 MHz to 5.162 dBi at 923 MHz. The radiation pattern is directional, which supports long-range communication requirements. These findings demonstrate that the proposed antenna design meets the specifications for LoRa communication and provides a wideband, directional solution that can enhance the reliability of IoT systems.

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

This study aims to design and implement a Fiber to the Home (FTTH) network based on Gigabit Passive Optical Network (GPON) technology using attenuation measurement as an approach to detect physical disturbances in optical fiber through modeling with Optisystem software. The research activities were conducted in a laboratory through several stages, including network topology design, system simulation using Optisystem, implementation of an FTTH trainer module, and attenuation measurement using an Optical Power Meter (OPM). Testing was carried out under various cable conditions, namely normal conditions, bending, damaged core, and variations in dropcore cable length to analyze their effects on attenuation values. The results showed that the attenuation values under normal conditions ranged from 14.94 to 16.23 dB, while under physical disturbance conditions such as bending and core damage, there was a significant increase in attenuation. The addition of cable length also contributed to an increase in attenuation of approximately 0.9 dB for every 5 meters. The Optisystem simulation results were consistent with the link power budget calculations and actual measurements, with a difference of approximately 0.1 dB. Furthermore, cable conditions with severe damage such as a broken core showed attenuation values exceeding 50 dB, which can be used as an indicator of physical disturbances. Overall, this study successfully demonstrates that the attenuation measurement method combined with Optisystem modeling is effective in detecting physical disturbances in FTTH GPON networks. The developed trainer module can also be used as a learning medium to understand attenuation characteristics and the performance of optical fiber networks in a laboratory environment.

Abstract

The rapid advancement of telecommunications necessitates continuous improvement in service quality, including 4G LTE networks. Padang Panjang's mountainous geography presents specific challenges, requiring a Quality of Service (QoS) analysis to evaluate public service levels. This study aims to measure and analyze the QoS of XL's 4G LTE network in Padang Panjang based on latency, jitter, packet loss, and throughput.The research employed an experimental method, conducting drive tests on planned routes. Data was collected using a smartphone with the TEMS Pocket application to measure parameters and Wireshark to analyze packet data. Results were processed using TEMS Discovery to assess performance against QoS standards.Findings showed an average throughput of 6.46 Kbps, latency of 0.000358 ms, jitter of 0.000356 ms, and packet loss of 0.3%. According to the TIPHON QoS standard, latency, jitter, and packet loss fall into the excellent category. However, throughput is classified as very poor. This indicates that while the XL 4G LTE network in Padang Panjang is stable and capable of supporting real-time services like VoIP and video conferencing, its data transfer speed performance remains severely inadequate. The study concludes that significant improvement in throughput is needed to meet overall service quality expectations.

Abstract

The fiber optic based trainer module designed for Politeknik Negeri Padang, especially in the Telecommunication Engineering Study Program for the Fiber Optic Communication System course, aims to improve students' understanding of optical fiber. This module provides an opportunity for students to practice optical fiber splicing and identify problems in the bus topology directly. The module design includes a block diagram showing the components and tools used, including an HLS (Heights Light Source) to provide the input signal and an OPM (Optical Power Meter) to measure the optical power at the Optical Distribution Point (ODP). Measurements are made to ensure attenuation in accordance with the predetermined link budget value: ODP1 with passive splitter 1:2 (8.0007 dB), ODP2 with passive splitter 1:4 (18.4517 dB), ODP3 with passive splitter 1:4 (28.9035 dB), and ODP4 with passive splitter 1:4 (38.555 dB). The measurement results show that correctly performed splicing results in attenuation below the link budget value. However, in ODP1, the disconnection of the pigtail caused the attenuation to exceed the link budget value by -50.00 dBm. The module proved to be effective in teaching but requires more attention to pigtail maintenance and the addition of a troubleshooting guide to improve its reliability.
