The news of the attack on the Indonesian National Police Headquarters (Police Headquarters) in online media caused controversial comments among terrorism observers. This is related to the protrusion of issues constructed by the media regarding the attachment of the "terrorist" label to the perpetrator of the attack on Zakiah Aini. Some observers said that the attack was an act of terrorism, but there were also observers who commented that the attack should not be speculated too quickly into an act of terrorism. The researcher uses a descriptive qualitative method with a framing approach to the analysis of the Robert N. Entman model on the online media Tribunnews.com and Republika.co.id which reports on the attack on the Indonesian National Police Headquarters by Zakiah Aini. The purpose of the study was to analyze the framing that was built in the Tribunnews.com and Republika.co.id media related to the news of the attack at the Police Headquarters and was expected to be a control for the two online media studied, especially in terms of media subjectivity. The results showed that the frames built by the two online media were very different. The frame built by Tribunnews.com is ideological stigmatic terrorism, namely the action was carried out because of an ideology under the pretext of jihad, while Republika.co.id led to shooting incidents. This study shows that the ideology brought by each media contributes to the construction of news.Pemberitaan peristiwa penyerangan Markas Besar Polisi Republik Indonesia (Mabes Polri) di media online menimbulkan komentar kontroversi dikalangan pengamat terorisme. Hal ini berkaitan dengan adanya penonjolan isu yang dikonstruksikan oleh media terkait pelekatan label “teroris” terhadap pelaku penyerangan Zakiah Aini. Beberapa pengamat mengatakan bahwa tindakan penyerangan merupakan aksi terorisme, namun ada pula pengamat yang berkomentar agar penyerangan tersebut tidak terlalu cepat dispekulasikan kearah tindakan terorisme. Peneliti menggunakan metode kualitatif deskriptif dengan pendekatan framing analisis model Robert N. Entman pada media online Tribunnews.com dan Republika.co.id yang memberitakan peristiwa penyerangan mabes polri oleh Zakiah Aini. Hasil penelitian menunjukkan bahwa frame yang dibangun oleh kedua media online tersebut sangat berbeda. Frame yang dibangun oleh Tribunnews.com adalah terorisme stigmatik ideology yakni aksi tersebut dilakukan karena adanya ideologi dengan dalih jihad, sedangkan Republika.co.id mengarah kepada insiden penembakan. Penelitian ini memperlihatkan bahwa ideologi yang dibawa oleh setiap media berkontribusi terhadap konstruksi berita.
