The research method used is research and development (R&D) with the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). However, in this study, the Implementation stage was not carried out because it was adjusted to the research objectives, which were only up to the feasibility test. The research was conducted from February to December 2025 at Sultan Ageng Tirtayasa University, SMAN 7 Kota Serang, and SMAN 8 Pandeglang. The feasibility assessment results of the E-LKPD based on subject matter experts obtained an average score of 84%, and media experts obtained an average score of 92%. Both are categorized as highly feasible. Furthermore, the teacher response test results obtained an average score of 86%, which is categorized as highly feasible. The small group trial at SMAN 7 Kota Serang obtained an average score of 71%. Meanwhile, the small group response test at SMAN 8 Pandeglang obtained an average score of 77%. The results of the student response test from both schools were categorized as feasible. Based on these results, it can be concluded that the developed E-LKPD is feasible for use in the learning process. date: 2026-02-24 type: Thesis type: NonPeerReviewed format: text language: en identifier: https://eprints.untirta.ac.id/58728/1/RATNA%20ANJANI%20PUTRI_2224190033_FULLTEXT.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/2/RATNA%20ANJANI%20PUTRI_2224190033_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/3/RATNA%20ANJANI%20PUTRI_2224190033_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/4/RATNA%20ANJANI%20PUTRI_2224190033_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/5/RATNA%20ANJANI%20PUTRI_2224190033_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/6/RATNA%20ANJANI%20PUTRI_2224190033_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/7/RATNA%20ANJANI%20PUTRI_2224190033_LAMP.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58728/15/RATNA%20ANJANI%20PUTRI_2224190033_CP.pdf identifier: PUTRI, RATNA ANJANI (2026) PENGEMBANGAN E-LKPD BERBASIS PROBLEM BASED LEARNING PADA MATERI VIRUS KELAS X.
