Abstract Public opinion surveys are an indispensable tool for studying politics in Southeast Asia. But publicly available data are often in short supply in the region. To this end, we introduce SIKAP, a harmonized and open-access dataset of 58 weekly surveys ( N = 95, 923) conducted in advance of, during, and in the aftermath of the 2024 Indonesian general election. We describe the data collection procedures and assess the quality of the sample. We demonstrate its utility by analyzing the effects of two political events on Indonesian voters’ attitudes in almost real time. First, we show that a constitutional crisis in August 2024 where the coalition of then President Joko Widodo (Jokowi) defied the Constitutional Court’s rulings led to a sharp but ultimately temporary decline in the public’s approval of Jokowi. Second, we show that voters who supported candidates other than Prabowo Subianto in the general election report large and persistent declines in support for democracy in the aftermath.
