The research subjects were 30 third-grade students of SDN Tambakaji 01 Semarang. Data were collected through interviews, questionnaires, and creativity tests, while data analysis was conducted using descriptive quantitative techniques and statistical analysis. The validation results indicated that the AKSI Book was categorized as highly feasible by media experts with a score of 96.25% and by material experts with a score of 92%. The teacher response showed a practicality level of 85%, which was categorized as very feasible. The effectiveness test revealed a significant improvement in students’ creativity after the implementation of the AKSI Book. This was indicated by the paired-sample t-test significance value of 0.000 (< 0.05), an increase in the mean creativity score from 68.93 in the pretest to 85.67 in the posttest, and an N-Gain value of 0.54 in the moderate category.
