Abstract

The development of computer networks has reached various aspects of life, with its wide use by groups and individuals. Computer network technology is very important because it has many advantages, such as developing a Wi-Fi 6-based computer network at LPK Sulthoon 4M to improve network performance and overcome the obstacles of slow connections that often occur when many devices are connected. The research method used is a field research approach with the stages of observation, interviews, documentation, and network quality testing. The network development process was conducted through the Network Development Life Cycle (NDLC) method, which includes requirements analysis, topology design, Wi-Fi 6 device implementation, and network performance testing based on Quality of Service (QoS) parameters, such as throughput, delay, jitter, and packet loss. The test results show a significant increase in data transfer speed with an average throughput of 5,049.71 kbps and a packet loss rate of 0%, and an average delay of 6.55 ms. The implementation of Wi-Fi 6 is proven effective in improving network stability and speed, thus supporting the smooth running of digital-based learning activities at LPK Sulthoon 4M.

Abstract

This study aims to design a VLAN network using a manageable switch at SMKN 3 Kota Bengkulu. The research method used in this study is the PPDIOO method. The hardware used in the configuration of the Virtual LAN network design is a Mikrotik Haplite Rb941 4 port and a D-link manageable switch, while the software used for the configuration is the Windows 10 operating system and a web browser. Data collection was carried out by observation, laboratory studies, and literature studies. The results showed that the quality of the VLAN network was better than the actual network as measured by the parameters of throughput, packet loss, delay, and jitter. The throughput value on the actual network was 198 Kb (poor) and increased on the VLAN network by 1367 kb (good). The actual network delay value was 3.56 ms (moderate) and decreased on the VLAN network by 2.53 ms (good). The jitter value also decreased from 8.30 ms (moderate) to 7.45 ms (good). Meanwhile, the packet loss value on the actual network and VLAN are both 0% (very good). In addition, the performance of file transfer speed between PCs using VLAN networks is better than the actual network, which is 10.9 MB/s for the actual network and 11 MB/s for the VLAN network. The use of VLAN networks can also improve network security because it can separate teacher and administration PCs as evidenced by the two PCs not being connected when the ping test was carried out.

Abstract

The computer network at SMK Negeri 06 Kaur is currently connected to the internet. However, the utilization of LAN network, especially the internet, at SMK Negeri 06 Kaur is not yet optimal, as there are still frequent network disruptions such as slow connections and a large amount of inappropriate content being accessed. This study aims to implement wireless network management based on a captive portal at SMK Negeri 06 Kaur. The study employs the Network Development Lite Cycle (NDLC) method. The implementation of captive portal-based network management is expected to improve network performance, enabling users at SMK Negeri 06 Kaur to access the network using a single username on a single device, with bandwidth allocation based on account profiles, and bandwidth management conducted via profiles connected to a simple queue. After implementing captive portal-based network management at SMK Negeri 06 Kaur, the network operates stably and effectively, with results including network speed limits and usage time limits.

Abstract

Internet network is a primary need in educational environment especially at SMP Negeri 3 of Lebong Regency of Bengkulu Province. SMP Negeri 3 of Lebong Regency already has internet network using Telkom Indihome provider with 30 Mbps Bandwidth. School does not have a system that can help monitor user internet access, where this can allow better control over user behavior on the network and can ensure that access to the website is in accordance with school policy. The internet access monitoring application is built using PHP programming language with MySQL database. The database is used to store the results of taking user internet access logs and blocked websites. The internet access monitoring application is accessed on the local network by activating the apache web server on the admin laptop and opening a browser to open a web-based application with the localhost/monitoring link. Based on the testing that has been conducted at SMP Negeri 3 of Lebong Regency, the results obtained are that the internet access monitoring application at SMP Negeri 3 of Lebong Regency based on the web can provide information related to users (IP Address) who are active on the internet network and information on sites (IP Address) that have been accessed by each user. In addition, this application can help block websites that are not desired to be accessed by users.
