This research was motivated by the low conceptual understanding of food webs among fifth-grade students at SD Negeri 1 Siraman in IPAS learning. This study aimed to determine the improvement of students’ conceptual understanding of IPAS through the use of Augmented Reality (AR)-assisted worksheets (LKPD). The research used a quantitative approach with a Pre-Experimental Design using a one-group pretest-posttest design. The population consisted of 18 students, and all students were selected as the sample through a saturated sampling technique. Data collection techniques included tests in the form of conceptual understanding pretest and posttest questions, as well as non-test techniques through observation and documentation. The data were analyzed using the Wilcoxon Signed Rank Test. The results showed that students’ IPAS conceptual understanding improved after the implementation of AR-assisted LKPD. The results of the Wilcoxon Signed Rank Test showed that the Asymp. Sig. (2-tailed) value was 0.000 < 0.05, indicating that Ha was accepted and H0 was rejected. This result showed a significant difference between students’ pretest and posttest scores in IPAS conceptual understanding. Therefore, the use of Augmented Reality (AR)-assisted LKPD enhanced fifth-grade students' conceptual understanding at SD Negeri 1 Siraman in the 2025/2026 academic year.
