For example, in the use of artificial intelligence (AI) technology as a means of education, business, trade (buying and selling) and use of services. Therefore, the author was encouraged to create the REPENA Chatbot as a means of increasing knowledge among teenagers by utilizing Artificial Intelligence (AI) technology.

From the results of this research, it can be concluded that increasing knowledge related to disaster education among teenagers using the REPENA Chatbot is effective and has the potential for great long-term benefits
