It encompasses a variety of strategies and communication channels aimed at delivering educational messages to the target audience. Audiovisual media refers to mediums that present both visual images and audio simultaneously. Visual media employs captivating visuals to engage and hold the attention of students while conveying information. WhatsApp is a social media platform that facilitates the exchange of various forms of messages and information, including videos and images. According to a survey by the Indonesian Ministry of Communication and Information Technology (Kominfo), 83% of the 171 million internet users in Indonesia utilize WhatsApp.
