Era 4.0 brought significant changes to all aspects of life, including education. Augmented Reality technology can be used to overcome obstacles in practical implementation. Practicum itself is an activity that is able to optimize students' understanding of the theory that has been studied. The problem studied in this study is the effectiveness of the Augmented Reality assisted practicum guide in thermochemical practicum with the aim of seeing the learning outcomes of students who learn to use Augmented Reality assisted practicum guides. This research was conducted at SMA Negeri 3 Tapung. Samples were taken using a random sampling technique with 2 sample classes, namely the control class and the experimental class where XI MIPA 1 became the control class and XI MIPA 2 became the experimental class. The results showed that the Augmented Reality-assisted practicum guide media improved student learning outcomes with a Ucount of -132. The results obtained bring one conclusion, namely effective practicum guiding media to improve student learning outcomes.
