This study explains why Generation Z performs acts of political participation. Political participation related to the political system in general can be divided into three attitudes, namely supporting, not supporting, and apathetic. The factors that give rise to the three attitudes are Political Trust and Political Efficacy. There are four research assumptions, namely: (1) If what appears is high Political Trust and Political Ef9icacy, the political participation that manifests is active support for the political system and the ruling regime; (2) if Political Trust is high while Political Efficacy is low, then what is manifested is political participation with a pattern of passive support for the political system and ruling regime; (3) If Political Trust is low and Political Efficacy is high then what appears is political participation that actively does not support or sometimes opposes the political system and regime in power, and; (4) If Political Trust and Political Ef9icacy are both low, then what appears is political participation that tends to be apathetic to both the political system and the ruling regime. The theory used is Generation Z, political trust, political efficacy, and political participation. Qualitative research approach, primary data collection techniques through open list questionnaires distributed online via Google Form, and triangulation data analysis methods. The number of research respondents are 13 people with ages between 17 to 18 years with Islam, Protestant, and Catholic religions. The results show that the research's first assumption is proven, namely the tendency of high Political Trust and Political Ef9icacy so that political participation that manifests is active support for the political system and the ruling regime.
