Temperature and humidity are important things in a chemical laboratory. By utilizing the internet, operators can remotely monitor laboratory temperatures and humidity with the Internet of Things (IoT) system. The Internet of Things (IoT) system can make it easier for operators to monitor temperature and humidity in chemical laboratories wherever and whenever. DHT11 sensor which functions as a temperature and humidity detector, NodeMCU ESP8266 microcontroller which functions as a data processor so that the DHT11 sensor detection results can be displayed on the monitoring website so that operators can see directly the results of temperature and humidity measurements at the chemical laboratory. This research was conducted at the Samarinda Industrial Research and Standardization Center. Data collection methods used are literature study, interviews, and observations. While the system development method used is prototype. As well as the supporting software used by the Arduino Integrated Development Environment, XAMPP, and Sublime.

The application of prototype smart security tools on doors using RFID with a NodeMCU-based telegram monitor in the process of opening the door aims to provide security and comfort and make work easier to make it faster, more effective and efficient. Where it can be used by lecturers and assistant lecturers who have been registered as staff and admin of the Computer Laboratory and the results of the track record will be monitored by the Head of the STMIK Computer Laboratory, Widya Cipta Dharma. This prototype was built using the C programming language with the Arduino IDE (Integrated Development Environment) application, and the system in the form of WEB using the PHP Native programming language using the Sublime Text 3 application and using the Mysql database and using the Telegram application as a medium for receiving notifications in the form of messages to be received by head of the Computer Laboratory. Based on the data analysis carried out above, it is concluded that the application of Smart Security on doors using RFID with a NodeMCU-based Telegram monitor is much faster, effective, efficient and safe and easy to use.
