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

Drawers for storing micro-sized electronic items that are usually used on campus are napolly-type drawers, which are plastic drawers, these drawers are considered ineffective because there is no notification that the drawer is open or the drawer is being opened by someone. In this case the authors designed and made the Drawer Door Security Prototype Using LDR and RFID sensors with a Microcontroller-based Sentora Platform. This system is equipped with an LDR sensor as a detector that if the drawer is opened too long then the alarm will be active until the door is closed again. RFID as a drawer door opener access. ESP8266 as a medium for sending data from the Arduino System to Sentora and using a web service to provide information to the drawer owner. If the LDR sensor detects an open drawer door for too long then ESP8266 will send information to the sentora that uses the web service as a notification. If the RFID Tag is registered, the solenoid opens. The state of the solenoid as a door lock will be displayed on the web service that the state of the solenoid has changed. From making this tool, it is expected that if there is someone who wants to break into a drawer it will be easily captured and more secure because it uses multiple layers of security

Abstract

Dalam pertumbuhannya tomat memerlukan kelembaban tanah dan suhu yang stabil agar tanaman tomat dapat tumbuh dengan baik, saat ini dalam memantau dan menjaga kestabilan kelembaban tanah dan suhu petani masih melakukan dengan cara manual. Salah satu perkembangan teknologi saat ini adalah IoT, yang mana dengan teknologi ini kita bisa melakukan pemantauan terhadap kondisi kelembaban tanah dan suhu pada kebun tomat melalui internet dan melakukan penyiraman otomatis jika kelembaban tanah dalam keadaan yang rendah dan suhu dalam keadaaan yang tinggi sampai kondisi kelembaban tanah atau suhu normal, Dengan adanya sistem ini diharapkan dapat mengurangi resiko kegagalan dalam pemeliharaan tanaman tomat dan diharapkan dapat mengontrol dan memantau keadaan tanah tanaman tomat itu sendiri, serta dapat meringankan pekerjaan petani dalam proses pemeliharaan dikarenakan proses yang dilakukan secara otomatis.
