Chatbot Application on Internet Of Things (IoT) to Support Smart Urban Agriculture

Information about the condition of the plant is certainly useful to do actions for plants to maintain the quality of these plants. The Internet of Things can help to inform the condition of the plant so that if there are circumstances that require further action such as watering can be informed immediately. In this study the tools used are wemos ESP8266 micro-controller that can be connected to Wi-Fi connected to the internet so that the data state from the sensor can be sent immediately via the internet. Sensors that are attached to plants are temperature, soil moisture, air humidity and light, the data sent to the web application uses the REST API service. The Web application sends the data to the mobile application and Line Chatbot. Natural Language Processing method in chatbot applications as message processing to approach Indonesian language. The result is the user's response in asking about the condition of the plant can be answered and notification of the condition of the plant can be sent. Data delivery must be received as fast as possible for the user to test it for how many seconds the sensor data is sent to the user, from 40 data samples there are delay about 1-3 seconds to be accepted by the user. For further research, sensors are needed which are more varied with the number and type of different plants and testing with sensor data compression.
