The development of cellular communication technology has transformed the way we interact and access information in ourdaily lives. Cellular networks based on GSM (Global System for Mobile Communications) remain one of the dominant technologies in the telecommunications world. However, in some cases, challenges related to signal coverage still persist, especially in remote areas or those affected by disasters. This research aims to address these issues. Researchers have built a GSM network using the Open BTS system, an open-source software project that has revolutionized the way cellular networks can be implemented flexibly and affordably. The construction of Open BTS is much more affordable than building conventional BTS, and in times of disaster, communication is crucial and must be quickly available. By using Open BTS and USRP N210 hardware, there is potential toovercome signal coverage issues in GSM networks. Based on the experimental data conducted, the placement distance of Open BTS and the height placement of Open BTS antennas need to be considered. This is because the farther the distance between Open BTS and the users' mobile phones, the higher the delay experienced during call and SMS services. In this study, the furthest distance of 20 meters and a height of 3 meters resulted in an average call delay of 14.27 seconds and an average SMS delay of 34.84 seconds. Conversely, the closest distance of 5 meters and an Open BTS antenna height of 0 meters compared to the user's phone resulted in an average call delay of 9.15 seconds and an average SMS delay of 11.65 seconds. The distance and height variations of Open BTS also affect the signal strength received by the users' phones.

The use of digital internet-based services has become a primary need, especially in academic environments such as campuses.Triple Play services, which include internet, IPTV, and VoIP, are increasingly used to support daily activities such as teaching,research, and administration. However, an increase in the number of users or traffic can pose a problem that potentially disrupts service quality. Therefore, this study was conducted to understand how the increase in traffic affects Quality of Service (QoS).The research methodology includes predicting incoming traffic, which involves estimating the number of users, calculating trafficintensity, and determining traffic volume over a day. Network quality testing involves calculating the power link budget. Service quality testing includes measuring throughput, packet loss, delay, and jitter using Ettercap and Wireshark software.The results of the study show that the daily traffic volume is 669,600 Mbit for internet services, 201,600 Mbit for IPTV services, and 787.2 Mbit for VoIP services. The traffic intensity over a day is 18.6 Mbps for internet services, 5.6 Mbps for IPTV, and 0.262 Mbps for VoIP, with peak traffic activity occurring at 12:00 PM, 1:00 PM, and 2:00 PM. The calculated attenuation of 21.65 dB and receiver power of - 17.66 dBm indicate that the network can provide good service quality. An increase in traffic will lead to higher throughput, no packet loss, and a reduction in delay and jitter. High traffic can cause strain on the network capacity, particularly if the capacity is insufficient to handle the volume of traffic. Insufficient network capacity will result in decreased service quality, characterized by reduced throughput and increased packet loss, delay, and jitter. In such conditions, the services that experience significant quality degradation are VoIP and IPTV. Keywords: FTTH, Triple Play, Network Traffic, Quality of Service, Network Quality.

This study presents the design and implementationof a smart aquarium system based on the Internet of Things(IoT) to optimize the growth performance of snakehead fish(Channa striata) through environmental control. The systemutilizes an ESP32 microcontroller connected to a DS18B20temperature sensor, PH-4502C pH sensor, and actuatorsincluding a water heater, dosing pumps, and an automatedfeeding system using LDR and servo. Temperature regulationis managed using a PI controller with Ziegler-Nichols tuning,while pH stabilization is achieved through automated injectionof sodium bicarbonate or citric acid solutions. Experimentalresults show that the system successfully maintains watertemperature at 30 °C and pH within the optimal range of 6.8–7.8. Furthermore, growth trials over 14 days indicate that theaquarium with the control system achieved an average SpecificGrowth Rate (SGR) of 2.561%, compared to 1.415% in theuncontrolled group. These results demonstrate that the smartsystem significantly enhances fish growth efficiency byensuring stable environmental parameters and accuratefeeding schedules.Keywords - Smart aquarium, IoT, Snakehead fish

In recent years, technology in the telecommunications sector has developed rapidly, especially with the global situation encouraging the use of long-distance communications. One of these developments is the use of the Raspberry Pi, abbreviated as Raspi, as a substitute for conventional computers for receiving and transmitting FM radio signals. Raspberry Pi is a mini and portable computer that can be used as an alternative to conventional computers in general, such as the use of teleconference media, offices, Big Data, and as a video player with high resolution. The problem in using a computer as an FM radio signal transceiver system is its complex and expensive infrastructure. When compared to the Raspberry Pi 3 with a price range of IDR 500,000 - IDR 1,000,000, a transceiver system using conventional computers requires a computer in general at a price far exceeding the said price. Using Raspi makes it easy to transmit FM radio signals by simply coding through the Raspi terminal. In this study, the authors propose a transmitter system using a Raspberry Pi 3B+ which is connected to a dipole antenna at a working frequency of 100 – 101 MHz. Raspi is operated using the SSH protocol for remote desktops. The operating system used is Raspberry Pi OS with the use of a MAC computer (MAC OS) as a remote desktop. The results show that the Raspberry Pi device can be used to transmit FM radio signals at a frequency of 100 - 101 MHz. The dipole antenna tested using VNA (Vector Network Analyzer) with a length of 71 cm and a linear form can transmit a signal with a VSWR of 1.08 - 1.95:1 at a working frequency of 94.9 - 103.06 MHz and a return loss of -28.1 dBm at a frequency of 98.98 MHz.

Kelangkaan dalam pengajuan sebuah saluran nirkabel (frekuensi) menjadi dilema untuk penyedia jasa maupun operator telekomunikasi. Teknologi radio kognitif memberikan solusi untuk meningkatkan efisiensi penggunaan spektrum secara signifikan. Radio kognitif terdiri dari 4 siklus langkah yaitu penginderaan spektrum, pengelolaan spektrum, spektrum berbagi, dan mobilitas spektrum yang mana penginderaan spektrum merupakan langkah yang paling penting dan kompleks. Dalam penelitian ini telah dianalisis penginderaan spektrum dengan deteksi energi pada frekuensi 825MHz dengan lebar pita frekuensi 20MHz menggunakan GNU Radio dan USRP N210. Teknik penginderaan spektrum yang digunakan adalah deteksi energi. Seluruh percobaan dilakukan dalam GNU Radio Companion (GRC) dan setelah itu data phyton akan dianalisis secara eksternal (MATLAB). Data untuk 30 frame waktu yang berisi 1024 sampel setiap frame dianalisis. Akhirnya, untuk menemukan nilai threshold yang optimal, probabilitas false alarm (Pfa) telah terhitung dalam 30 frame waktu untuk 5 nilai threshold berbeda di -98 dB, -99dB, -100 dB, -101 dB, -102 dB. Nilai akhir yang dicari adalah nilai threshold dengan Pfa persis dibawah 5%.
