Students experience difficulties in understanding solar system material in the science learning process, one of the causes of this problem is the absence of media when learning takes place. The aim of this research is to analyze the level of validity of 3D teaching aids using solar system material, and to analyze students' responses to 3D teaching aids using solar system material to train concept understanding. This research uses a type of research and development, which is usually called the Research & Development model. The research that will be carried out is research with a development type, using the 4D (Four D) model which has 4 stages, namely, define, design, develop, and disseminate, but this research is limited only to the develop stage, namely validity testing and test student responses. The instruments used are interview instruments, validation questionnaire instruments and student response questionnaire instruments. The subjects in the research consisted of media, material and practitioner experts (science teachers), while the sample used 30 students. The validity level of 3D teaching aids on solar system material reached a percentage value of 91.25% in the "Very Valid" category, while the results of student responses showed a percentage value of 90.05% which was included in the "Very Good" category. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/47108/1/Jantriyani_2281200065_Full%20Text.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/4/Jantriyani_2281200065_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/5/Jantriyani_2281200065_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/6/Jantriyani_2281200065_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/7/Jantriyani_2281200065_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/8/Jantriyani_2281200065_Ref.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/9/Jantriyani_2281200065_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/20/Jantriyani%202281200065_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47108/23/Jantriyani_2281200065_01.pdf identifier: JANTRIYANI, JANTRIYANI (2025) PENGEMBANGAN ALAT PERAGA 3D IPA UNTUK MELATIH PEMAHAMAN KONSEP KELAS VII PADA MATERI TATA SURYA.
