Abstract

The aim of this research was to developed a computer network system based on router os and web server authentication embedded in a mini PC, user login authentication process applied to a router hotspot system combined with mini PC so it can produce a good management system or which can be called as smart hotspot. The intelligent hotspot which is built has the ability to perform user management and authentication. User management built into this intelligent hotspot system has the ability to define user authority, bandwidth limitation hierarchy, and limitations to sites and user-accessible content, the system is capable of detecting malware, phishing or pornographic content or sites. This capability is created by implementing and modifying firewall features in mikrotik OS. User authentication is built by incorporating hotspot features in the router OS as well as web server embedded in a Raspberry PI mini PC. User authentication is applied with two login process that is first login process by entering username and password with purpose to determine user permissions, then second login process in the form of question according to given user class. Questions given in the form of problems related to the subjects Prodi Computer Systems. The results obtained from the construction of this intelligent hotspot system is a hotspot system that can provide education for users and provide more convenience services for users and learning media courses Computer Network Administration at STMIK Asia Malang. Based on the test system that has been done some weaknesses to the authentication and limitation that have been made, but from the weakness in general can be concluded that the system can run quite well.

Abstract

This study discusses the system to overcome the current problems, namely the lack of discipline in washing hands and checking body temperature before entering the building which is one of the important things in implementing health protocols during the covid-19 pandemic. Both of these things are still often violated and are things that are often underestimated by visitors and the lack of firmness by officers in responding to these violations. In this study, a tool is designed to be used to check temperature and wash hands automatically which later will be an indicator to open a gate or automatic portal as a path or entrance to a building/building which is expected to be able to help officers work to be more disciplined. visitors who do not apply the health protocols that have been determined and are also able to minimize direct physical contact that will be caused by the current conventional system so as to minimize the risk of transmission of covid19. This tool uses a temperature sensor gy906/mlx 90614 as a non-contact temperature sensor and uses ultrasonic as a temperature sensor. Object distance detection, and also uses a dc motor actuator as a driver to open or close the gate. In the testing of the tools that have been carried out, the results obtained that the automatic gate system is able to run well by being controlled by both indicators, namely the temperature sensor and automatic sink as the main input in the whole system.

Abstract

Technology is currently developing very rapidly, one of which is the technology of hatching eggs in chicken farms. The technology used is a chicken egg incubator why do farmers need an incubator in hatching because many farmers experience hatch failure, so that crop failure does not occur, this incubator is designed to achieve an ideal temperature of 37-40 0C, this ideal temperature is a good temperature in hatching chicken eggs, if it is too hot it will cause the quality of the eggs to decrease and even cause death. Controlling the temperature in this incubator uses the fuzzy mamdani and the DS18B20 sensor. The DS18B20 sensor is used to get the temperature in the incubator as input for fuzzy logic, the output of this system is the fan speed (PWM) and lights to make the temperature warmer. Based on the simulation results using fuzzy logic at a normal temperature of 39.5 0C with a total of 25 eggs the fan speed reaches normal, namely 160 PWM.
