Abstract

One of the problems with internet networks in rural areas is the difficulty of connecting cable-based internet because the distance is too far, wireless/wireless-based internet networks can be an alternative solution to these problems. A research analysis of the Power Link Budget calculation was carried out in planning the outdoor wireless internet network in the village. Kutanagara Garut. The test was carried out using the Power Link Budget calculation method and simulation using the Ubiquiti ISP Design Center application with a LiteAP GPS transmitter device and a NanoBeam 5AC receiver. Network planning is made using the Point to Point (PTP) system in the 5725 MHz frequency band to be precise at 5725 MHz Sub Band NII-3. The parameters tested are SOM (EIRP, margin signal), free space loss (FSL), Fresnel zone clearance (FZC), coverage area, signal strength obtained and internet speed capacity. The results of the calculations and configurations show that the EIRP value of the sender is 36 dBm, the EIRP of the receiver is 36 dBm, the maximum bandwidth is 20 MHz, Fresnel zone clearance is 3.4 m and the received signal strength is -49 dBm. These results have met the standards set by KOMINFO and a network design can be made. The results of the network simulation show that the internet network design has covered the entire area of Kutanagara Garut Village with an estimated signal obtained is -49 dBm, with a signal margin of 46.2 dB which already meets the standards of TIPHON with network classification included in the outstanding category (very good). Has a maximum internet capacity of 147 Mbps consisting of 74 Mbps download speed and 74 Mbps upload speed

Abstract

The need for information exchange that encourages the development of telecommunications technology that can be a medium for delivering information to connect various places on the earth's surface or called terrestrial telecommunications. In wireless communication, the use of radio waves as a medium for propagation of information is considered more effective than physical media such as cables. A high radio frequency value such as X-Band will result in a smaller dimensional device. The use of microstrip type antennas has advantages in terms of small dimensions, inexpensive fabrication, and simple design but has low gain. Therefore, the design of a microstrip antenna with the array method becomes a solution that can be used in applications in terrestrial telecommunications. In this research, a microstrip antenna with a biquad-shaped patch has been designed and realized with a 4×1 array method that operates in the X-Band frequency band. This antenna works at a frequency of 11.96 GHz with a return loss of -23.51 dB and a VSWR of 1.13.

Abstract

In telecommunications, filters are devices that play an important role in a telecommunications system. One of them is a bandpass filter that can pass signals with a passband frequency and cut off the stopband frequency. In the process, various kinds of signal interference will be found that can interfere with the quality of electromagnetic waves. This research will design and realize a microstrip bandpass filter that can pass the 6 GHz frequency with a minimum bandwidth of ? 100 MHz for C-Band Radar applications. This filter is designed using a square open loop resonator which will be simulated using the CST studio suite 2019 which will be realized using a 4-epoxy FR substrate. In this study the design of a microstrip bandpass filter was carried out with three stages of design simulation to determine the characteristics of the square open loop resonator, split ring resonator, and defected ground structure design. Based on the results of the final design of the microstrip bandpass filter design, the simulation results obtained work at a resonant frequency of 6 GHz with a return loss value of -32.098 dB, an insertion loss value of -0.40148 dB and a bandwidth of 97.3 MHz. The results of bandpass filter fabrication measurements were obtained at a resonant frequency of 6 GHz, the results obtained were in accordance with the required specifications with a return loss of -29.09 dB, an insertion loss of -2.75 dB with a bandwidth of 485.4 MHz.

Abstract

MIMO (Multiple-Input Multiple-Output) Antenna Technology improves wireless network performance by allowing the use of multiple transmit and receive antennas simultaneously. MIMO antennas use antenna elements in an array, such as circular microstrip antennas, to increase signal throughput and reliability. This research simulates and develops a circular microstrip antenna into a 1×4 axe MIMO with array, operating at 2.4 GHz. The simulation shows return loss (S11) -60.913 dB, insertion loss -50.439 dB, VSWR 1.001, bandwidth 116.3 MHz, and gain 5.709 dBi. The results of fabrication and measurement achieve return loss (S11) -61.69 dB, insertion loss -43.16 dB, VSWR 1.00, bandwidth 137.2 MHz at a frequency of 2.4260 GHz. Even though there is a frequency shift of 260 MHz between the simulation and measurement results, the design of this antenna is successful according to the desired specifications.

Abstract

Penelitian bertujuan merancang UTM berbasis aplikasi open-source yang mampu melakukan Threat Mitigation dan menerapkan manajemen trafik pada jaringan TCP/IP. Metoda Threat Mitigation menggunakan SNORT sebagai IPS untuk melakukan tindakan terhadap ancaman serta melakukan monitoring trafik yang diintegrasikan dengan Splunk sebagai SIEM. Metoda Traffic Policy menggunakan SQUID sebagai Proxy untuk melakukan manajemen trafik. Pengujian perfomansi jaringan dilakukan dengan mengukur parameter QOS terlebih dahulu pada setiap perangkat akses untuk melihat performansi jaringan saat terjadi serangan sebelum dan sesudah implementasi UTM. Serangan DDOS berupa ICMP Flood dan SYN Flood. Setelah melakukan simulasi serangan DDOS selama 5 menit, Threat Mitigation mampu melakukan drop terhadap paket yang berasal dari serangan DDOS sebanyak 232409 paket dengan nilai throughput maksimum 1,823 Mbps, lebih baik dari throughput yang dihasilkan serangan DDOS sebelum implementasi UTM yaitu 869 Mbps. Hasil indeks parameter QOS setiap perangkat akses jaringan memiliki nilai indeks 4, lebih baik dari indeks parameter QOS sebelum implementasi UTM yaitu 2,843. Traffic Policy pada UTM mampu melakukan efisiensi bandwidth sebesar 4,66% atau 943,6645 MB selama 5 hari kerja dari total volume cache 20,23 GB, dengan menerapkan web cache untuk akses HTTP dan limitasi throughput sebesar 300 KB pada ekstensi file image, audio, video dan executeable berukuran diatas 20 MB.

Abstract

Utilizing of 5G technology has become a major focus in the development of more advanced and efficient telecommunications networks. In this context, 5G coverage prediction becomes an important aspect in network planning to ensure optimal user experience. In this study, we explore the use of Random Forest algorithm to predict 5G coverage, with special emphasis on the hyperparameter optimization process to improve model performance. We conduct experiments with various hyperparameter combinations, including 'max_depth', 'max_features', 'min_samples_leaf', 'min_samples_split', and 'n_estimators', using hyperparameter optimization techniques. The results show that by paying attention to the optimal combination of hyperparameters, we managed to significantly improve the performance of the model. The optimized model produces a Minimum Root Mean Squared Error (RMSE) of 0.6, which is much better than the Random Forest model without hyperparameter optimization which has an RMSE of 1.14. The result of this study confirms the importance of the hyperparameter optimization process in improving the accuracy and consistency of the Random Forest model for 5G coverage prediction. The results have important implications in supporting the development of a successful 5G network infrastructure in the future.

Abstract

This study aims to examine the influence of literacy-based learning strategies on students’ critical thinking skills at SMA Muhammadiyah 01 Medan. A quantitative approach with a quasi-experimental design was employed. The population consisted of all eleventh-grade students, and the sample was selected purposively. Data were collected through critical thinking tests administered before and after the implementation of the treatment. The data analysis revealed a significant improvement in students' critical thinking skills following the application of the literacy-based learning strategy. These findings indicate that literacy-based learning strategies are effective in fostering students’ critical thinking by encouraging deep reading, analytical thinking, and the development of logical and reflective arguments.
