The Use of Miniature Kelong as a Learning Medium for 7th Grade Students at SMP Negeri 10 Bintan

Abstract

The objective of the study is to improve students' learning outcomes in calculating the density of a kelong using a miniature kelong as a learning medium. The author guides students in calculating the density of the miniature kelong, which is made from plastic straws and used bottles with a known volume. This research uses a quantitative descriptive method, employing pre-test and post-test scores. The students' scores were then analyzed descriptively and quantitatively. The population consists of 34 students from the 7th grade of SMPN 10 Bintan, all of whom were also used as the sample in this study. The results show a significant improvement of 18 points or 28%, based on the average pre-test score of 64 and the average post-test score of 82. Using the miniature kelong as a medium, students were able to calculate the maximum mass capacity of the kelong.
