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.

Abstract

The rapid growth of information technology has increased the demand for reliable, secure, and efficient computer network infrastructures. MikroTik is widely adopted as a cost-effective networking solution, particularly for small to medium-scale networks. This study aims to analyze the advantages and disadvantages of using MikroTik in computer network implementations based on previous empirical studies. This research employs a literature review method by analyzing more than fifteen scientific articles published within the last five years. The reviewed studies focus on bandwidth management, firewall configuration, network security, Quality of Service (QoS), and network monitoring using MikroTik RouterOS. The findings indicate that MikroTik offers several advantages, including flexible configuration, comprehensive RouterOS features, effective bandwidth management, and relatively low implementation costs. However, several limitations were identified, such as configuration complexity, non-optimal default security settings, performance degradation under high traffic loads, and limited scalability for large enterprise networks. With proper configuration and the integration of additional security mechanisms, MikroTik remains an effective and efficient solution for small to medium-scale network implementations.

Abstract

The rapid advancement of automation technology in the fisheries sector has increased the demand for efficient and accurate fish weight measurement systems. Conventional manual weighing methods are often time-consuming and prone to human error, particularly in high-volume environments. This study aims to evaluate the performance of a microcontroller-based automatic fish weighing system using a load cell sensor with real-time output. The proposed system integrates a load cell sensor with an HX711 amplifier module and an Arduino Uno microcontroller to measure fish weight and display results instantly via an LCD. The performance evaluation focuses on key parameters, including accuracy, measurement error, response time, and system stability. Experimental testing was conducted by comparing prototype measurements with a standard digital scale under various load conditions. The results indicate that the system achieves high accuracy exceeding 98%, with an average error below 2%. The response time ranges between 1–2 seconds, demonstrating the system’s capability for real-time applications. Additionally, the system exhibits good stability with minimal fluctuations in repeated measurements. These findings suggest that the proposed prototype is reliable and efficient for practical use in aquaculture and fish market environments. The system also supports digital transformation in fisheries through improved measurement accuracy, reduced human error, and enhanced operational efficiency.

Abstract

Marble cutting activities in campus workshop environments generate substantial concentrations of airborne particulate matter, particularly PM2.5 and PM10, which pose serious risks to occupational health and ambient air quality. This study presents the design, implementation, and experimental evaluation of a real-time IoT-based dust exposure monitoring system with emphasis on sensing performance, data reliability, and environmental analysis. The system employs a laser scattering dust sensor (PMS7003) integrated with an ESP8266 microcontroller for data acquisition and edge preprocessing, and utilizes Wi-Fi communication with the MQTT protocol for low-latency data transmission to a cloud-based monitoring platform. Sensor calibration was conducted using linear regression against a reference air quality monitor, resulting in improved measurement accuracy with a coefficient of determination (R²) of 0.96 for PM2.5 and 0.94 for PM10. The system operates with a 5-second sampling interval and applies a moving average filter (window size = 5) to reduce signal noise. Experimental deployment was carried out in a campus marble workshop over a 5-day observation period. Results indicate that during active cutting sessions, PM2.5 concentrations ranged from 85 to 210 µg/m³ and PM10 from 120 to 350 µg/m³, significantly exceeding WHO air quality guidelines (PM2.5: 15 µg/m³, PM10: 45 µg/m³, 24-hour mean). Peak concentrations were observed within the first 10 minutes of operation, followed by gradual dispersion depending on ventilation conditions. Network performance evaluation shows an average transmission latency of 1.8 seconds, packet delivery ratio of 97.2%, and system uptime of 99% over the testing period. Power consumption analysis indicates an average current draw of 82 mA, enabling efficient long-term deployment. The results confirm that the proposed system provides accurate, stable, and high-resolution monitoring of particulate pollution, supporting real-time decision-making for exposure mitigation and smart environmental management in campus settings.
