Abstract

The hospital is an integral part of a social and health organization with the function of providing services, disease healing and disease prevention to the community. Predicting the number of medical devices is essential for managing a hospital, managing human and financial resources, and for properly distributing material resources. If the number of medical devices can be predicted accurately, this will become the basis for planning and making decisions for hospital managers. Based on these reasons, an electronic tool is needed that can determine the number of medical device needs with a high degree of accuracy and the display of the results for easy reading and data collection. From system testing, the need for medical devices in the following month will decrease in providing some medical devices because they still have a lot of stock in the previous month. The Backpropagation Algorithm can carry out the prediction process, but whether or not the error value and the output is very much influenced by the determination of parameters such as the amount of learning rate and the number of neurons in the hidden layer.

Abstract

Artificial Intelligence is a part of computer science that is made so that machines (computers) can do work as well as what humans do. The Unity 3D application is a game engine which is a software for processing images, graphics, sound, input, etc. which is intended to create a game, although not always for games. Nowadays, games have developed a lot according to traditions and times. Therefore, there are a lot of unattractive game designs because the AI is not responsive and feels stiff, and requires the Fuzzy Logic Method. Fuzzy Logic is a problemsolving control system methodology that is suitable for implementation in systems, ranging from simple systems, small systems, embedded systems, PC networks, multi-channel or workstation based data acquisition, and control systems.

Abstract

Expert systems are a branch of artificial intelligence that studies how to adopt an expert's way of thinking in solving a problem and making a decision to draw conclusions. In this case the expert system is used to diagnose anemia. What is discussed is how to determine the type of disease, how to overcome anemia in the community and designing expert systems using technology. nemia caused by a lack of red blood cells or malfunctioning red blood cells in the body. This causes reduced oxygen flow to the organs of the body. Vitamin B supplements can be used for low vitamin levels. The Bayes method is a method for producing parameter estimates by combining information from samples and other information that has been previously available. Bayes' theorem is used to calculate the probability of an event occurring based on the effects of these observations. From several studies that have been done, it is found a solution to prevent anemia. Anemia can cause weakness and dizziness due to lack of blood, which can lead to complications. The objective is to provide information to assist the general public in diagnosing anemia and getting a preciseand accurate diagnosis.

Abstract

Research to install IPCop and honeypot on server computers and implement IPCop by way of configuration to protect the server from unauthorized parties. The software used in this research is IPCop, Manjaro Linux, Shootpress, Windows 10, and Virtual Box. The results of this study indicate that the implementation of IPCop as a security system on the server can be done and can run well. IPCop is able to protect servers from hacker attacks very well, even using IPCop hackers are not able to ping the server, so hackers cannot find out information about the target server. Honeypot implementation as a security system on a linux server can be done and can run well. Honeypot is able to protect the server from hacker attacks well through its virtual server. So that hackers do not know where the original server is and the hacker will only attack the virtual server from the honeypot and think as if the server is the real server. In this case IPCop is better than the honeypot in the server security system

Abstract

Although there are many security methods that can be used to block DDoS attacks, for now these methods are arguably less effective, because many hackers have known bugs from the system or security methods. From the background of this problem, testing the security of Linux Mint servers, Linux Mint without VPN and Anti DDoS, implementing network security from hammer attacks on Linux Mint Linux servers with VPN and Anti-DDoS, and testing DDoS and VPN attacks have been successfully implemented. on linux mint. Anti-DDoS and VPN are able to prevent DDoS attacks on Linux servers by blocking unknown IPs from accessing the server and redirecting attacks to virtual IPs provided by the VPN.
