This study uses a Research and Development (R&D) approach with the ADDIE (Analyze, Design, Develop, Implement, Evaluate) model to produce an assemblr application-based learning media on the material of earth structure in class V SDN Kebaharan 2. Data validity techniques use a feasibility test by material, language and media experts, product trials to obtain student feedback, and effectiveness tests using normalized gain tests with pretest-posttest. The results of this study, namely the feasibility test, showed that the learning media obtained an overall average score of 90.77% with a very feasible category. Positive responses from 42 students with an average of 88% indicated that the learning media was well received. The effectiveness test showed a significant increase in student learning outcomes with an N-gain value of 78%, indicating that the assemblr application media is effective in improving students' understanding of visual and abstract concepts such as the structure of the earth. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/47620/1/DWI%20APRIANTI_2227200115_FULLTEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/18/DWI%20APRIANTI_2227200115_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/2/DWI%20APRIANTI_2227200115_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/3/DWI%20APRIANTI_2227200115_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/4/DWI%20APRIANTI_2227200115_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/5/DWI%20APRIANTI_2227200115_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/6/DWI%20APRIANTI_2227200115_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/7/DWI%20APRIANTI_2227200115_REFF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/47620/8/DWI%20APRIANTI_2227200115_LAMP.pdf identifier: APRIANTI, DWI (2025) PENGEMBANGAN MEDIA PEMBELAJARAN APLIKASI ASSEMBLR PADA MATERI STRUKTUR BUMI BERBASIS TEKNOLOGI 3 DIMENSI PADA MATA PELAJARAN IPAS DI KELAS V.
