This scientific article investigates the construction of political identity through hashtag movements on Instagram, focusing on the "#kadrun" hashtag related to Anies Baswedan, a presidential candidate for the 2024 election in Indonesia. Using the framing analysis method by Zhong Dang Pan and Gerald M. Kosicky, the study examines the structural dimensions of political identity content by observing and analyzing the hashtag from October 3, 2022, to May 3, 2023. The results reveal three Instagram accounts actively contributing and acting as political identity buzzers, uploading 89 to 92 contents within seven months. The hashtag frames Anies Baswedan and his supporters as a radical Islamic group, seeking to establish a caliphate, and intolerant, potentially leading to political polarization based on religion, community, and ethnicity in the upcoming election. These findings hold implications for understanding the impact of social media content on political discourse and polarization, especially among young active voters who rely on Instagram as a source of information during elections.
