<![CDATA[Encyclopedia teaching materials can enhance the learning process by being clearly and attractively packaged, which helps prevent boredom and engages both students and teachers. This is particularly beneficial for grade V science teachers at SDIT Al-Irsyad Pamekasan, who have observed that many students' achievements fall below the KKM (Minimum Completeness Criteria). By integrating Islam and science into these encyclopedia teaching materials, teachers can better support students' understanding of human motion systems and strengthen their confidence in Allah SWT. This research aims to evaluate (1) the feasibility and (2) the effectiveness of these integrated encyclopedia materials at SDIT Al-Irsyad Pamekasan. Using the Research and Development (R&D) approach with the ADDIE model, which includes Analysis, Design, Development, Implementation, and Evaluation, the study involved fifth-grade students as subjects. Results indicate that the encyclopedia is highly valid, effective, and attractive, meeting user needs. Validation results show that material experts rated the encyclopedia at 96%, design experts at 87.5%, language validation at 80%, and science learning experts at 92%, all in the "very decent" category. The encyclopedia's attractiveness was rated at 88.4%. The effectiveness of these teaching materials is further demonstrated by pre-test and post-test scores: the average pre-test score was 68.48, and the post-test score was 87.59. Manual t-test calculations showed tcount (5.145) was greater than ttable (1.703) at a significance level of 0.05, leading to the rejection of the null hypothesis (Ho) and acceptance of the alternative hypothesis (Ha). This signifies significant improvement, confirming that the developed encyclopedia teaching materials are highly effective and suitable for teaching human motion systems.]]>
