Abstract

Computer network security has become a crucial aspect in the digital era as users increasingly depend on network technologies for daily activities. Beginner users represent one of the most vulnerable groups to cyber security threats due to limited technical knowledge and low security awareness. This article aims to provide a comprehensive review of fundamental concepts, common threat types, and basic network security strategies that are relevant for beginner users. The research method employed is a descriptive literature review of scientific articles and academic publications related to computer network security published between 2018 and 2025. The collected literature was analyzed to identify dominant threats and effective protection mechanisms for beginner users. The results indicate that threats such as malware, phishing, ransomware, and unauthorized access remain major security issues. The implementation of basic security mechanisms, including strong password policies, firewalls, antivirus and anti-malware software, regular system updates, and improved user awareness, has proven effective in minimizing security risks. With adequate understanding and proper implementation of these measures, beginner users are expected to apply network security practices more safely, responsibly, and efficiently.

Abstract

This study aims to optimize the 4G LTE network in the Kubu Gulai Bancah area, West Sumatra, which is a suburban area with weak signal and unstable internet speed challenges. The main problem identified is that the network quality is not yet optimal based on Telkomsel's Key Performance Indicator (KPI) parameters, as well as the need for an appropriate optimization method to improve this quality. The research methodology involves a drive test using the G-NetTrack Pro application on a Redmi Note 13 Pro 5G smartphone to collect RSRP, SINR, and Throughput data. The collected data is then processed using MapInfo for visualization and analysis, and simulated with Atoll software for optimization planning. Initial drive test results showed that while RSRP was mostly in the “very good” category (55%) and Throughput was predominantly ‘good’ (84%), SINR was still dominated by the “poor” category (56%). Optimization was performed using physical tuning, specifically adjusting the tilt and re-azimuth of the antenna at Site Campago Ipuh 2, Sector 1, with an azimuth change from 0° to 65°. After optimization, the bad spot area for RSRP decreased from 13.2% to 10.89%, and for SINR from 14.1% to 13.21%. The good category for Throughput also increased from 30.5% to 32%. This optimization successfully improved signal coverage quality and network performance significantly.

Abstract

This study aims to design and analyze the performance of Optical Line Terminal (OLT) and Optical Distribution Cabinet (ODC) devices in the Fiber to the Home (FTTH) network trainer module at the SKSO G316 Laboratory, Padang State Polytechnic. The research methods included design simulation using Optisystem software, physical implementation of the trainer module, and attenuation measurement using an Optical Power Meter (OPM). The results show that attenuation under normal core conditions (orange) is stable in the range of 14.94–16.23 dB, while core bending (green) and core damage (blue) conditions cause a significant increase in attenuation to 16.28 dB and 16.01 dB at a wavelength of 1310 nm. The length of the dropcore cable (10 m, 15 m, 20 m) showed an effect on the increase in attenuation with an additional attenuation increase of 0.9 dB per 5 meters. The simulation results and actual measurements are consistent with the link power budget calculations and meet the technical specifications with total attenuation below the maximum limit of -28 dB. This trainer module is useful as a learning medium for analyzing FTTH network performance and the impact of physical disturbances on optical fiber transmission.
