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

Noise is an environmental problem that arises due to the rapid growth of communication, industrialization, transportation, space, musical instruments and population. The purpose of this research is to detect the frequency value of sound intensity that can cause deafness and sound frequency that is safe for human hearing. The sound intensity value detected by the sensor is displayed in Real Time through Lcd. This tool research uses three parts, namely control, input and output, where Arduino nano functions as a tool controller, sound sensor as an input that functions as a sound detector around, dfplayer and Lcd as an output that functions to display sensor readings in the form of numbers and emit sound. Sound sensor reading data uses 4 categories, namely 0-30 dB “very safe”, 30-60 “safe”, 60-90 “dangerous” and 90-100 “very dangerous”, and the sound will sound according to the value displayed on the sound sensor to Arduino to facilitate the monitoring process. After the whole tool is assembled the tool is tested in two different places, namely Taman Pala and SDN 9 Tapaktuan South Aceh. The results of testing the tool in the nutmeg garden show a sound frequency number of 53.26 dB in the “safe” category, while the test results at SDN 9 show a frequency number of 98.93 dB in the “Very dangerous” category when the room is noisy.
