#StopSexualHarassmentInPublicTransport: Online-based Social Movement on Twitter

Public safety and security, especially for women, remain at stake when they must leave the house and travel alone. In 2022, PT KAI Commuter (the only commuter railway provider in Indonesia) noted that as many as 70 cases of sexual harassment occurred on electric trains (KRL). These unpleasant incidents have generated public anger in social media using hashtags "stop sexual harassment in public transport". This paper discussed how those hashtags became public sentiment on Twitter and created online-based social movement to stop sexual harassment in public transport. The finding shows that the visibility of social movements on social media platforms can mobilize public sympathy against sexual harassment in public transport.
