Abstract

Online attendance system with the use of raspberries as a local server to synchronize system data on the server and attendance data processing, nodemcu as a tool that can transmit hostpot signals for attendance and android connected to the nodemcu hostpot with the android application for each event attendance in taking attendance . In this system Attendance can be taken at a distance of less than 30 meters by utilizing the nodemcu hostpot signal, an attendance device with additional battery power in anticipation of a main power outage, a local Raspberry pi server that is always synchronized with a public server so that when the internet network dies requesting attendance can still be processed and stored, the application that stores the mac address of the event participants so that there is only one warak on one user to minimize attendance cheating fraud, attendance taking and event permits can be done on the android application, taking attendance allows can be taken together to overcome attendance taking . This attendance system utilizes Restfult API technology with JavaScript Express programming framework, microcontroller with Arduino IDE C programming, websites with React.js JavaScript programming framework, and android applications with React Native JavaScript programming. In the design of this attendance system has several methods, namely problem identification, literature study, consultation, system analysis, system design, and implementation. The result of this system is a system that can streamline the taking and minimize attendance fraud

Abstract

Campus laboratories, especially the Andalas university campus, faculty of agricultural technology, are very important supporting facilities for the continuity of education. In this laboratory, students carry out practical learning which significantly makes students understand the material better. Laboratory management activities at the Andalas campus faculty of agricultural technology are all forms of recording goods and activities that occur in the laboratory. Given the importance of laboratory functions, good laboratory management is an absolute necessity. This allows the campus to more easily get real data from the use of the laboratory by students and activities in the laboratory. This study aims to produce a web and android-based laboratory loan management information system, because compared to a paper basis, laboratory lending and management activities using web and android-based information systems are considered more efficient to implement, because with the web and android all forms of recording can be done easily. easy to do and if data is needed, all authorized parties can easily get the data. The method used in designing this campus laboratory information system uses the waterfall method where this method uses a sequential software lifeflow approach starting from the stages of analysis, design, implementation, testing and maintenance. Based on this research, it is concluded that with the existence of a web and android-based management information system, it is hoped that laboratory loan management activities at the Andalas campus, faculty of agricultural technology will be better.
