PENGEMBANGAN MEDIA FLIPBOOK LIVING HADIS BERBASIS STEAM UNTUK PENGUATAN KARAKTER SOPAN SANTUN ANAK USIA DININIM.: 24204031008Mutiara FajarauthorThis research is motivated by the lack of introduction of hadith in the learning process at RA Al-Fattah Pasundan as a foundation for character building in children, the limited use of media as teaching materials to introduce hadith, and the low level of children's understanding of living hadith, which is reflected in their behavior that does not yet fully demonstrate polite and courteous attitudes such as using words (sorry, please, thank you, excuse me). Therefore, it is necessary to make learning efforts thru the design of media with an attractive and appropriate appearance to introduce the values of politeness Character education in early childhood is a crucial foundation for shaping a child's personality, morals, and spirituality. One way to strengthen Islamic character, particularly good manners, is through a living hadith approach that integrates the teachings of the Prophet Muhammad (peace be upon him) into daily life. This study aims to develop and test the feasibility, practicality, and effectiveness of a STEAM-based living hadith flipbook in strengthening good manners in early childhood at RA Al-Fattah Pasundan, East OKU Regency. The research method used was Research and Development (R&D) with the Tessmer model, which included selfevaluation, expert review, one-to-one, small group, and field testing. The study subjects were 16 children in Group B. The validation results by design, material, and language experts indicate that the flipbook media "Lala and Agas's Adventure to Outer Space" falls into the very valid category in terms of content, construct, and language aspects with an average score of 91%. The practicality test at the one-toone stage received an average score of 66%, while the small group stage obtained an average score of 84%, categorized as very practical and suitable for use. The effectiveness test thru pre-test and post-test shows a significant improvement in children's ability to recognize living hadith and apply polite character. The average pre-test score of 36% (Developing category) increased to 90% (Very Good Developing category) in the posttest. The results of the Paired Sample test showed a significance value of 0.001 (<0.05), which means there is a significant difference before and after the treatment. Thus, the STEAM-based living hadith flipbook media is declared valid, practical, and effective in strengthening the character of politeness in early childhood. This media can become an innovative learning tool that integrates Islamic values with a modern learning approach in the digital era.371.33 Media Pembelajaran2026-05-18UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
