Abstract

This study examines the issue of students' low understanding of chemical elements at the MTsN 1 Nganjuk, which is influenced by the abstract nature of the material and the lack of interactivity in its presentation. The primary objective of this research is to evaluate the effectiveness of PUZDIK (Periodic Table Puzzle) as a gamification-based learning medium in enhancing students’ conceptual understanding in science. The study employed a quantitative approach with a quasi-experimental method using a one-group pretest-posttest design. The research involved 33 eighth-grade students from MTsN 1 Nganjuk, selected through purposive sampling. The instruments used were essay-type questions for both pretest and posttest, analyzed using the Wilcoxon Signed Ranks Test and N-Gain calculation. The results showed a significant improvement between pretest and posttest scores, with a significance value of 0.000 (< 0.05), and N-Gain scores categorized as high (≥ 0.82), with an average increase reaching 100%. These findings indicate that the PUZDIK media is effective in strengthening students’ conceptual understanding in science. The implication of this study highlights the importance of developing learning media that integrate visual elements and gamification to foster a more engaging, active, and meaningful learning experience.

Abstract

This research aims to investigate the effects of Fukushima nuclear waste on fish organs in the Japanese sea, particularly concerning the relationship between pollution levels and their impact on marine organisms. Through a scientific literature analysis, the findings indicate a positive correlation between contamination levels and the accumulation of radioactive compounds in fish organs. Marine organisms, especially those exposed to high contamination levels, tend to experience adverse effects on vital organs such as the liver, kidneys, and gills. The radiation's impact poses a high risk to the marine environment, especially for organisms at higher trophic levels with a greater potential for contamination. Beyond ecological impacts, this also affects economic and social aspects, posing threats to the fishing industry and the well-being of communities. The study underscores the need for international cooperation in addressing cross-border challenges posed by nuclear waste and calls for further research to deepen our understanding of the impacts and determinants involved. Overall, this research makes a significant contribution to efforts to protect the marine environment and sustain marine ecosystems amidst global challenges associated with nuclear activities
