This research is aimed at determining the effectiveness of using video that was integrated with local potentiality to improve students' concept mastery in natural science learning. A quasi-experimental, non-equivalent control group design was used to pursue the purpose of this research. The population was all first-year students of State Junior High School 2 of Jetis that was located in Bantul Regency. Two groups observed and assessed in this research were VII C as the experimental group and VII D as the control group. While the control group students learned natural science concepts through conventional teaching methods, the experimental group through video. The assessment used to measure students' concept mastery was a multiple-choice test related to the concepts of energy in the systems of life. The data related to students' concept mastery were analyzed using the one-way ANOVA and the normalized gain analysis. The findings revealed that the use of video that was integrated with local potentiality was effective to improve students' concept mastery in natural science learning. Furthermore, the significance of this research mainly lies in its findings that can be used as references to review or design natural science learning that is integrated with local potentiality. © 2018 Published under licence by IOP Publishing Ltd.
