Wireless networks are one of the best alternatives in building practical and flexible computer networks that have high mobility. Most of them use wireless networks to support existing cable networks, but on wireless networks, they still use cable media as a backbone of the access point, which supports communication users can access the internet and find information. The problem of using cables as backbone media can be a significant challenge in places that are difficult to reach by wires. Wireless networks provide convenience and convenience that is high enough to use. As long as they are in an area that is supported by a wireless network, users can access the internet at any time. To make the wireless network connected to the internet safe and easy to use, we can create a user authentication system based on Multi-Factor Authentication (MFA) that can be used to authenticate and authorize. In general, each user can use existing wireless network services by verifying users based on Wifi Protected Access 2 Pre-Shared Key (WPA2-PSK). The purpose of this research is to develop a wireless network that uses Multi-Factor Authentication (MFA) based user authentication to be able to connect to the wireless network to increase security and provide the use of existing wireless networks. The research method used in this study uses descriptive qualitative research methods, with data collection using literature study and observation techniques. After analysis and design, it can be concluded that user authentication is based on Multi-factor Authentication (MFA) in a safe and user-friendly manner that can determine the users who are allowed and not allowed to use wireless networks.
The purpose of this research is to create a wireless network design in Cijambe Village using WDS so that Cijambe Village can enjoy internet services through wireless networks, which can be used to find information, communication, and market products owned by village communities. A wireless network is one of the best alternatives in building a computer network that is practical and flexible and has high mobility. Most organizations use wireless networks to support existing cable networks, but in reality, the wireless network still uses Unshielded Twisted Pair (UTP) cable media as the backbone of Access Points (AP). Cijambe Village is a village located in Paseh District, Sumedang Regency. Cijambe village is divided into two hamlets, namely Cijambe Hamlet and Parugpug Hamlet. Cijambe village has an area of 357 hectares. The research method used in this study is a qualitative descriptive research method. The steps taken in this research are analysis and design. the conclusion is that wireless network design for digital villages using Wireless Distribution System (WDS) has a better degree of flexibility than the backbone that uses Unshielded Twisted Pair (UTP) cable. Radio wave signals from 19 AP units can reach the entire area of Cijambe Village which has an area of 357 hectares and is divided into 2 hamlets namely, Hamlet Cijambe and Parugpug Hamlet. The design made has thought of a standard level of security with routers and firewalls.
Tujuan dari penelitian ini adalah merancang jaringan wireless yang memanfaatkan jalur wireless sebagai backbone pada semua access point kecuali basestation point yang tetap mempergunakan kabel UTP sebagai backbone-nya dan memperluas area jangkauan jaringan wireless yang mampu mencakup seluruh bagian di Universitas Widyatama. Hasil desain jaringan wireless dengan WDS akan diuji dengan melakukan simulasi. Kemudian pengujian akan difokuskan pada parameter delay, packet loss, throughput, dan jitter dengan menggunakan metode Quality of Service (QoS) menggunakan aplikasi Axence netTools. Desain jaringan wireless dengan Wireless Distribution System (WDS) memiliki tingkat fleksibilitas yang lebih baik daripada backbone yang menggunakan kabel Unshielded Twisted Pair (UTP). Hasil pengujian menunjukkan bahwa throughput, delay, packet loss, dan jitter menunjukkan hasil yang bagus. Hasil pengujian throughput didapatkan nilai rata-rata throughput dengan presentase sebesar 90%, dapat dikategorikan BAGUS dengan indeks 3, sedangkan hasil pengujian delay didapatkan nilai rata-rata sebesar107,8 dapat dikategorikan SANGAT BAGUS dengan indeks 4, kemudian nilai rata-rata packet loss dengan presentase 2%, dapat dikategorikan BAGUS dengan indeks 3, dan hasil pengujian jitter diperoleh nilai yang bervariasi dengan nilai rata-rata jitter sebesar 1,71 ms, dapat dikategorikan BAGUS dengan indeks 3.
The purpose of this research is to provide ease in reading articles on the standard production and use of imitation leather. Help reduce the level of errors in viewing the standard article production and use of materials by the operator. Operators can more easily enter and change data on the standard production and use of faux leather. It is helping operators who are elderly and have vision problems in seeing and determining production standards and material usage. Bits of help reduce night shift operator errors that lack concentration when looking at the standard production book and the use of faux leather due to drowsiness. This study uses a qualitative approach to data collection techniques using observation, interviews, and literature study. The system development model used in this study is the Waterfall model. The results of this study indicate that the application of production standards and the use of imitation leather material is very easy to use, fast enough in processing or carrying out its functions, very helpful for operators who have problems with their vision, it is quite feasible to replace the previous production standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
