Abstract

Nypa palm worm (Namalycastis rhodochorde) is a new species of Polychaeta class found in Sei Kakap area. Apart from being obtained from the river coast, cultivation is one way to get worms, but the cultivation of nypa palm worm is still within the scope of the lab and is done manually. Manual cultivation has a problems, especially in controlling water salinity which affects the survival or survival rate of worm. Therefore, this requires an Internet of Things in installation of worm cultivation. This system aims to control the salinity of the water and then monitor the salinity and temperature of the water as well as the temperature and humidity of the air. Another goal is to control water salinity which affects the survival rate of worms. The results of monitoring and controlling the water salinity will be displayed on a website-based application. Arduino Uno is used as hardware that controls the system, NodeMCU ESP32 is used as a tool to connect to the server, water salinity sensor is used to measure water salinity, DS18B20 sensor is used to measure water temperature, as well as DHT11 sensor is used to measure air temperature and humidity. The results of testing the reading system of each sensor obtained an error value 0,017% and 0,032% water salinity sensors, 0,015% DS18B20 sensor, as well as 0.011% and 0.003% DHT11 sensor. Application of the system can reduce water salinity by 1-3 ppt and resulted in the survival rate of worms by 41%.

Abstract

One of the important things in the management of the lecture building is the need for a security system to lock the door. This is necessary to avoid the possibility of theft and negligence in opening or closing the door at certain hours. The purpose of this study is to implement an Internet of Things-based door security control and monitoring system using a mobile device. This system is a substitute for door security that uses conventional locks. The system can be accessed by setting the operating time from 07.00-17.00. If there is a change in operational time, the admin can reset the operational time. Before the operating time ends, the speaker gives an automatic door lock warning, and the door is automatically locked and cannot be accessed. In addition, the system is equipped with a door alarm using a buzzer and a notification is sent via the application when the door is forcibly opened. The door control process starts by reading the operating time and the status of the door lock solenoid. If the initial status of the door lock solenoid is locked, the RFID tag sends data to the RFID reader, then the door lock solenoid opens. The test results show that the response time for opening and locking doors using RFID is 26,22 seconds and 22,25 seconds. The response time to open and lock the door using the application is 5,03 seconds and 5,34 seconds, respectively. The average response time when the door is forcibly opened is 14,83 seconds
