Desa Motu is an area that experiences limited internet access due to the unavailability of conventional ISP services and weak cellular signal coverage. This study aims to develop a community-based RT/RW Net network system to provide internet access by utilizing Starlink as the main ISP and distributing connectivity through networking devices such as MikroTik routers, access points, switches, and fiber optic media. Network testing was conducted by measuring download and upload speeds using network testing ap-plications, evaluating connection stability through latency (ping) measurements, and assessing signal coverage at several user locations. The results show that the implemented RT/RW Net network is able to provide a stable internet connection with consistent speeds at different testing times, as well as optimal signal distribution across multiple measurement points. The authentication system using vouchers, PPPoE, hotspot login, and MAC Binding functions properly, and the free educational access feature also operates effectively. These findings indicate that the RT/RW Net–based community network model can serve as an affordable and sustainable solution for expanding internet access in rural areas.

PT. Radysa Cosmetic is one of the businesses engaged in the distribution of beauty and cosmetic products such as Make Up, Body Care, and Skincare located in Medan City, Jl.Sisingamaraja, Medan Amplas District. However, it has a problem, namely the lack of access points in and out causing disruption to the efficiency of warehouse operational activities so that there is an increase in the number of customers and couriers who come directly to Radysa Cosmetic to make purchases because there is a spike in orders for goods or purchases at the beginning and twin dates every month. The research method used is qualitative in the form of descriptive, where data is collected through direct observation and research as well as interviews with the warehouse head. The results of this study indicate that by implementing the utilization or addition of access points in and out of the warehouse area, it can realize the optimization of the warehouse layout to increase the efficiency of operational activities in the Radysa Cosmetic warehouse.

This study aims to develop a Learning Management System (LMS) for kepalangmerahan management education in the Indonesian Red Cross Youth at SMK Wiworotomo Purwokerto The methodology employed is the Knowledge Management System Life Cycle (KMSLC) with the Meyer and Zack cycle approach, along with the spiral knowledge model by Nonaka and Takeuchi. Network infrastructure involves the internet, wireless access points, and private internet networks. Hardware and software include android devices with browser applications. Resource and data identification is carried out through discussions, interviews, and data entry, utilizing sources from PMR trainers, the Indonesian Red Cross website, and scholarly literature. The Knowledge Management (KM) team consists of PMR trainers, LMS developers, administrators, and PMR members. The system is implemented using WordPress and the TutorLMS plugin, with verification and validation testing conducted through black box testing. The research results demonstrate the successful development of the kepalangmerahan management education LMS in PMR SMK Wiworotomo Purwokerto, with a specific focus on disaster management education materials. This study contributes to improving effective learning access within PMR.

IEEE 802.11ax WiFi 6 is the current standard for wireless local area network (WLAN) technology which is a development of the previous standard, namely IEEE 802.11ac (WiFi 5). WiFi 6 has new features that are superior to WiFi 5. For example, it can operate in the 6 GHz frequency band, use 1024-QAM modulation, and use a maximum of 8 spatial streams. In general, to test and verify the implementation of a network technology standard, researchers can buy hardware on the market that has implemented the standard in its entirety or only certain mandatory features. Apart from using hardware directly, testing can also be done using software simulations. This research aims to study the WiFi model in the ns-3 simulator and simulate the IEEE 802.11ax WiFi 6 network. The simulation is carried out to measure the uplink throughput that can be achieved by WiFi 6 with various numbers of client stations (STA) and various distances between the Access Point (AP) and STA. The simulation results show that the throughput value will decrease with increasing AP-STA distance and the number of STA. The maximum throughput value obtained in the simulation with 5 STA at a distance of 2 meters from the AP is 655.41 Mbps.

This research uses Cisco Packet Tracer as a simulation tool for implementing WI-FI technology in a star topology. WI-FI technology is a wireless communication technology that allows electronic devices to connect wirelessly to a local area network (LAN). Star topology is one of the most commonly used network topologies, especially in wide local area networks (WLAN). This research uses Cisco Packet Tracer to model and simulate a star topology in WI-FI. This framework utilizes powerful simulation tools to facilitate network management and monitoring. Star topology can improve network performance because each device has a direct communication path to the access point. This research provides information about the basic concepts of WI-FI technology, introduces star topology and explains its implementation using Cisco Packet Tracer.

QoS (Quality of Service) on the internet network at STIKUBANK University Semarang should be maintained optimally as one of the efforts to meet the needs of internet users on campus. The purpose of this research was to determine the quality and service of the Wifi network in Building D8, STIKUBANK University Semarang so that it can determine the level of satisfaction of the users of the wifi network and minimize network disruptions early on so that the internet network is always at its best.. The QoS (Quality of Service) parameters used in this study are bandwidth, delay, packet loss and jitter based on the TIPON standard by monitoring the internet network at the Access Point of each room using the Axence NetTools application. Some of these rooms include: WR Room, YPPMI Room, TU Room, Meeting Room, Rector Room and HR Room. This research has benefits both theoretically and practically. Theoretically, the benefit of this research is that it can be a reference for other researchers who will discuss QoS (Quality of Service) analysis of Wifi networks at schools, colleges or other institutions. And practically, the results of this study can be used as material for study and information for STIKUBANK University Semarang regarding the QoS (Quality of Service) of the Wifi network in Building D8, STIKUBANK University Semarang. Based on the results of the research that has been done, it can be concluded that the QoS (Quality of Service) of the Wifi network in Building D8 of Stikubank University (UNISBANK) according to the TIPON standard is satisfactory with a percentage of 91.67% and is included in the grade B category.   Keyword : QoS (Quality of Service), Wi-Fi, TIPHON, Axence NetTools.

Computer network technology is developing rapidly, and wired networks are being replaced by WiFi technology. The limitation of the WiFi coverage area is the main problem with this technology. Therefore, it is necessary to design for optimal placement of access points. This study analyzes the need for access point placement at KSOP Tanjung Mas Port, Semarang, where the need for internet connection via WiFi is very high. Simulation Annealing and Trilateration method is used in this study to determine the position of the access point. With the point blankspot method can be reduced.
