Abstract

Abstract— The increasing demand for high-speed, reliable internet access in the digital era has led to the decline of conventional copper-based networks and the rise of fiber-optic-based solutions. This study focuses on the design and development of a Fiber To The Home (FTTH) network using Gigabit Passive Optical Network (GPON) technology in Banaran Subdistrict, Sukoharjo Regency, an area with growing economic activity, particularly in the Micro, Small, and Medium Enterprises (MSME) sector. The implementation of GPON is seen as a critical infrastructure enhancement that supports regional development, education, and digital connectivity. The research methodology began with site surveys using Google Earth Pro and QGIS to collect spatial data such as household coordinates and pole locations. This data was then processed using Setics Sttar Planner version 2.3.12, enabling automatic calculation of optimal cable routes, equipment locations, and required component specifications. The resulting FTTH design covers four neighborhood units (RW 1, RW 2, RW 4, and RW 5), serving a total of 630 homepasses. Key components of the network include 1 Optical Line Terminal (OLT), 2 Fiber Distribution Terminals (FDTs), 46 Fiber Access Terminals (FATs), and 125 poles. The power link budget calculation, essential to determining signal feasibility, produced theoretical receive power values between -15.089 dBm and -14.144 dBm. Field implementation and post-deployment measurements were conducted in RW 1 and RW 2 to validate the theoretical model. Adjustments were made due to site constraints, including reductions in splitter and FAT counts, as well as cable length modifications. Measured receive power values ranged from -16.71 dBm to -16.22 dBm, which still fall within acceptable standards defined by PT. iForte Solusi Infotek (between -10 dBm and -21 dBm). The differences between calculated and actual measurements were attributed to splicing quality, variations in cable deployment, and environmental factors. Overall, the study successfully demonstrates the feasibility and efficiency of deploying GPON-based FTTH infrastructure in semi-urban regions like Sukoharjo. The integration of digital tools for planning and field validation ensures optimal network performance, supporting the goal of bridging the digital divide and enhancing socio-economic development in the area.

Abstract

Fiber optic networks currently have a lot of interest, so a network monitoring system is needed that guarantees quality and speed of repair if mass disruption occurs. in research [1] regarding fiber network damage detection using IoT with the use of a 1:4 splitter and the use of a detector that can work at a wavelength of 650nm so that it can detect damaged cables with output in the software. So in connection with this, the author wants to develop the results of this research by using a 1:8 splitter and carrying out detection using the LDR sensor and NodeMCU ESP32 using IoT (Internet of Things) technology. The ESP32 NodeMCU will receive data in the form of light intensity values ??at each ODC from the LDR sensor. And then sent to a database that is connected directly to the Android application. The cable identification process occurs in three states: normal, warning, and error. The test and analysis results show that the hardware device can work well, with attenuation in the passive splitter cable of 10.28 dB and a light source with a wavelength of 650 nm. Cable detected as damaged is indicated by an output in the software with a delay of 4.56 s.

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

Fiber to the Home (FTTH) is an optical fiber-based communication technology with high bandwidth capacity and low interference, making it the main choice for telecommunication network development. This study aims to analyze cable attenuation under various cable conditions in the FTTH trainer module. The research method involves designing an FTTH network using Optisystem and measuring cable attenuation under normal conditions, broken core, one splice, and two splices. The Optisystem simulation produced received power levels of -8.992 dBm (1310 nm) and -8.920 dBm (1550 nm), which correspond well with direct measurements on the trainer module. Measurements showed that normal cable attenuation was around 14 dB, cables with broken cores exceeded 50 dB, one splice added 0.2 dB, and two splices added 03–0.5 dB. The results indicate that splices in optical cables contribute to an increase in attenuation.

Abstract

Wireless fidelity (WiFi) is a wireless connection using radio technology so that users can transfer data quickly and safely. However, at a certain distance there is a decrease in signal speed on WiFi, as happened in Tursina's rented house located in Pasar Baru. When away from WiFi, the internet speed will decrease and the connection becomes unstable. Therefore, an antenna that has a high gain is needed in the form of a microstrip antenna with a working frequency of 2.4 GHz. This final project aims to design a microstrip antenna with the Defected Ground Structure (DGS) method for wireless fidelity (WiFi) applications at a frequency of 2.4 GHz, and analyse antenna parameters such as return loss, VSWR, bandwidth, gain, and radiation pattern. Where the antenna design uses CST Studio Suite 2019 software. After the simulation results are as desired, then fabrication or manufacture of the antenna is carried out. The simulation results after optimising are return loss -40.79 dB, VSWR 1.019, bandwidth 543.9 MHz, gain of 1.312 dBi and bidirectional radiation pattern. After the simulation is carried out, the next fabrication or manufacture of the antenna. In the measurement of the fabricated microstrip antenna using Vector Network Analyser shows a return loss value of -16.07 dB and VSWR 1.375. the measurement results of the fabricated antenna meet the specifications of a good antenna for WiFi applications.
