Logaritma Udayana 2025 is an annual written and scientific mathematics competition organized by the Mathematics Students Association (Himatika) of Udayana University. This event featured three competition categories: essay writing, public poster presentation, and KMS (Mathematics and Statistics Competition). The competition is nationally tiered across Indonesia, with the following categories: essay competitions for high school and university levels, digital poster competition for high school and university levels, the Mathematics Competition for elementary, junior high, and senior high school students, and the Statistics Competition for senior high school students.

The Logaritma Udayana 2025 event was conducted in a hybrid format (online-offline). Registration for all three competitions was conducted online. The poster and essay competitions were held entirely online, while the KMS competition was held in a hybrid format: the preliminary round took place on October 18, 2025, via Zoom Meetings.
