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

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 Unified Threat Management (UTM) berbasis aplikasi open-source yang mampu melakukan Threat Mitigation dan menerapkan manajemen trafik pada jaringan TCP/IP. Metoda Threat Mitigation menggunakan SNORT sebagai Intrusion Prevention System (IPS) untuk melakukan tindakan terhadap ancaman serta melakukan monitoring trafik yang diintegrasikan dengan aplikasi Splunk sebagai Security Information and Event Management (SIEM). Metoda Traffic Policy menggunakan SQUID sebagai Proxy untuk melakukan manajemen trafik. Pengujian perfomansi jaringan dilakukan dengan mengukur parameter Quality of Service (QOS) terlebih dahulu pada setiap perangkat akses untuk melihat performansi jaringan saat terjadi serangan sebelum dan sesudah implementasi UTM. Serangan Distributed Denial of Service (DDOS) berupa Internet Control Message Protocol (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 dari total volume cache 20,23 GB, dengan menerapkan web cache untuk akses Hyper Text Transfer Proctocol (HTTP) dan limitasi throughput sebesar 300 KB pada ekstensi file image, audio, video dan executeable berukuran diatas 20 MB.   Abstract This final project aims to design Unified Threat Management (UTM) based on open-source application that capable to mitigate threat and implement traffic management on TCP/IP network. Threat Mitigation method uses SNORT as Intrusion Prevention System (IPS) and integrated with Splunk as Security Information and Event Management (SIEM). Traffic Policy method use SQUID as Proxy to implement traffic management. Network performance testing will be carried out by measuring the QOS parameters on each access device to be able to see network performance when an attack occurs before and after UTM implementation. The Denial Distributed of Service attacks was simulated with Internet Control Message Protocol (ICMP) Flood and SYN Flood. After simulating DDOS attack for 5 minutes, Threat Mitigation was able to drop 232409 packet that originating from DDOS attack with a maximum throughput value 1.823 Mbps, was better before implementation of UTM which is 869 Mbps. The result of the QOS index parameters for each access device has an index value is 4, was better than before implementation of UTM, which is 2.843. Traffic Policy was able to perform bandwidth efficiency of 4.66% or 943.6645 MB from a total cache volume of 20.23 GB, by implementing web cache for Hyper Text Transfer Protocol (HTTP) access and limiting throughput of 300 KB of image, audio, video and executable file size above 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.
