<![CDATA[This study aims to determine the effectiveness of using the Busy Book method in developing the fine motor skills of children aged 4–5 years at the Kindergarten. This study employs a quantitative approach with a quasi-experimental design, specifically a non-equivalent control group design involving an experimental group and a control group. Data collection techniques involved tests (pre-test and post-test), whilst data analysis was conducted using descriptive and inferential methods. The results of the study indicate that there was a more significant improvement in fine motor skills in the experimental group compared to the control group. The average pre-test score for the experimental group was 32.08, increasing to 45.33 in the post-test, with an average increase of 13.25 points. Meanwhile, the control group saw an increase from an average of 32.58 to 40.58, with an average increase of 8.00 points. Furthermore, the standard deviation of the post-test scores for the experimental group (2.774) was smaller than that of the control group (3.579), indicating more stable and consistent results. Based on the research findings, it can be concluded that the Busy Book medium is effective in improving fine motor skills in early childhood. The implications of this study suggest that the use of interactive, concrete, and enjoyable learning materials is crucial in supporting the optimal development of young children]]>
