Wireless networks have been widely used for internet services in the business, banking, cafe, military, and education sectors as well as in educational institution such as University of Muhammadiyah Kotabumi. The internet facilities available on campus are used to serve lecturers, education staff and students in accessing the internet. Currently, various models of wireless network technology with the 802.11 standard have now been widely used, both with a frequency of 2.4 GHz and 5 GHz, even computer and smartphone vendors have installed wireless network cards on their products to facilitate user mobility. However, in reality, especially in University of Muhammadiyah Kotabumi, the points of wifi have not been found in all locations.To make it easier to add wifi points, Wireless Distribution System (WDS) technology is used. WDS is a technology that receives signals and radiates back. WDS is used to optimize the use of network resources to cover the service area. Using WDS allows wireless network connection with multiple access points without having to use cables. All access points used for WDS must be configured using the same radio channel and encryption key. Based on the explanation above and looking at the problems that exist in the System and Technology Study Program, Universitas Muhammadiyah Kotabumi, the rsearcher conducted a research entitled Implementation and Analysis of Wireless Distribution System Networks at the Faculty of Engineering and Computer Science, Universitas Muhammadiyah Kotabumi. The computer network that has been implemented is monitored and analyzed. Monitoring and analyzing throughput, delay, and packet loss parameters of the connected WDS network, namely Access point 1, Access point 2, and Access point 3 using Axence Nettools. The measurement results after the WDS network has been implemented are obtained The throughput value is 85%, packet lost is 0.007456 and delay is 0.66ms. Based on the implementation and analysis carried out, it can be concluded that the results obtained meet user expectations by referring to the THIPON standard.

The use of computer networks is increasingly growing, this causes the installation of network devices to be more and more diverse. With so many network devices installed, the risk of damage that occurs makes network administrators take a long time to detect the damage. To overcome this, it is possible to create a Telegram Bot for monitoring mikrotik and other devices connected to the networks. Mikrotik OS through script logic that is inputted through the features can inform network damage to network administrators. Telegram bot is a bot or robot that is programmed with various commands to carry out some instructions given by the user. By using bots, you can perform network management on Mikrotik, making it easier for a network administrator to work. This study aims to monitor network devices, send notification messages that enter the Telegram application to be able to find out the status of active and inactive users and devices.

Persaingan dunia usaha yang ketat maka perusahaan harus pintar-pintar melihat peluang dan kebutuhan masyarakat, sehingga perusahaan mengeluarkan program Pembiayaan Ulang untuk para konsumen yang ingin menjaminkan kendaraannya dan pembayaran kendaraan tersebut dilakukan secara cicilan. Dalam penentuan pemberian Pembiayaan Ulang masih mengutamakan analisis karyawan yang diberi tugas dalam mensurvei kondisi konsumen yang akan mengajukan Pembiayaan Ulang pada FIF Group Kotabumi, sehingga dalam penentuan penerima kredit terkadang tidak objektif sehingga sering terjadi kredit macet yang menghambat perputaran uang pada FIF Group Kotabumi. Sistem Pendukung Keputusan (SPK) merupakan salah satu solusi perusahaan yang membantu melakukan pengambilan keputusan terhadap konsumen layak atau tidak layak menerima pembiayaan pembiayaan ulang. Dibutuhkan suatu metode perhitungan yang digunakan untuk menyelesaikan permasalahan dengan banyak kriteria. Salah satu metode perhitungan yang digunakan adalah Metode Technique for Others Refrences by Simillarity to Ideal Solution (TOPSIS). Konsep dasar dari metode TOPSIS yang didasarkan pada konsep bahwa alternatif terbaik tidak hanya memiliki jarak terpendek dari solusi ideal positif tetapi juga memiliki jarak terjauh dari solusi ideal negatif. Hasil dari sistem pendukung keputusanyang dibangun ini dapat menghasilkan keputusan yang lebih objektif. Menghasilkan 6 nasabah diterima dan 4 nasabah ditolak yang dapat digunakan sebagai rekomendasi penentuan kepada PT. FIF Group Cabang Kotabumi.

Server is a place to store data and information that is owned so that it can be accessed by anyone and connected workstations from anywhere. If the server room gets too hot or too humid, it can cause your server to not work properly.air with too high humidity can damage the hardware on the server, for example, equipment can cause a short circuit caused by rust. The ideal humidity level for a server room is between 40 and 50%. As the humidity level increases, the amount of water vapor in the air increases. This can cause changes in vapor to liquid, electronic devices cannot be exposed to water. Many mistakes that are often made by server owners are by placing temperature and humidity detection sensors in the room, the temperature detection sensor should be placed in the rack of each server at each rack level, which is positioned at the front and back of the rack. The device that is commonly used in making Internet of Things applications is Arduino, Arduino is used as a link between the internet and sensors so that data from these sensors can be accessed. via the internet to set the behavior of specific equipment. In this study, Arduino was used because Arduino is an opensource device, the programming language used is C language and the Python programming language can also be used. From the availability of the library, there are many libraries that are ready and easy to use. Temperature and humidity detection in this study uses a DHT 11 temperature and humidity sensor connected to an Arduino device that is connected to the internet via a local network.

The Internet, and in particular the World Wide Web, is widely used by businesses, government agencies, corporations and individuals. Based on that fact internet service providers offer a lot of choices, and it can be confusing so we end up choosing the expensive one just to make sure we get the speed we need. All internet service providers must have interference, be it caused by the weather or broken cables and so on. The load balancing method can be used to send and receive internet access on a network through several gateways. When we subscribe to an internet connection with 2 ISPs load balancing can be used as a bandwidth balancer. The principles of load balancing remain the same in any environment, although circumstances and applications will differ. Internet service providers use a balancing strategy to handle fluctuating amounts of incoming internet traffic. Load balancing effectively minimizes server response time and maximizes throughput. The role of load balancing is sometimes likened to that of a traffic police, as it is meant to systematically direct requests to the right location at a given moment, thereby preventing costly congestion and unforeseen incidents. The load balancer must ultimately provide the performance and security needed to sustain complex IT environments, and the complex workflows that occur within them.
