Online shop websites are currently increasingly developing, with online shop websites making it easier for buyers and sellers to see the goods being sold anywhere and at any time and sellers can promote the goods they sell to the wider public. The aim of creating this website is to help the Jaya grocery store to be able to check online and manage the stock of basic food items and also avoid several errors that can occur such as errors in inputting quantities and prices. It is hoped that by designing this web-based sales application it can help grocery stores successful in increasing sales and expanding the marketing process in online and offline forms. The process of designing this application uses the prototype method for making this website with the aim that the final process of this design can then be used according to the needs of the Jaya grocery store. Currently we are entering technological progress which is increasing day by day, because this development covers several aspects, even all aspects involving human life. With the development of this technology, this technology is not only used as a communication medium but also to expand the business network of business actors. one of these business actors is the Jaya grocery store, in order to be able to compete healthily in the global world, it needs a tool or something that can be used to reach the market as expected, in this case, namely to improve its business or to increase its sales scope. The purpose of this research is to be able to design an information system for ordering goods online or on a web basis, how to help the Jaya grocery store to increase sales volume and further expand the marketing process in online and offline forms.

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.

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.

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 quality of Academic Information System Service (SIAKAD) which has been implemented by STIH Muhammadiyah Kotabumi has not been optimal as expected. In accordance with that, it was seen that there is incompatibility between the plan and the reality. An audit related to the maturity level of TI management on the implementation of SIAKAD STIH Muhammadiyah Kotabumi is important to be conducted in order to get the recomendation of service improvement. Evaluation was done through questionaire, interview and document of STIH Muhammadiyah Kotabumi. This research used COBIT 5 consisting of EDM 04, APO04, APO 07, BAI 04, DSS 01, dan MEA 01. The data source was gotten from the Head of STIH Muhammadiyah Kotabumi, the Head of administrations, the Head Communication Centre, TI Staff, and Academic Staff. An analysis was done by using descriptive interpretative based on COBIT 5.
