Institutional Repository UIN Sunan Kalijaga YogyakartaPENGEMBANGAN E-LKPD BERBANTUAN VIRTUAL BIOLOGY EXPERIMENTS ONLINE LABS (OLABS) PADA MATERI SISTEM EKSKRESI SEBAGAI BAHAN AJAR PESERTA DIDIK KELAS XI SMA/MANIM.: 22104070034Noverta Vika AlessandriauthorThis study was motivated by students’ lack of motivation in learning about the excretory system due to the limited availability of engaging and interactive teaching materials. This study aims to: 1) Examine the development of biology E-LKPDs supported by virtual biology experiments via Online Labs (OLabs) on the excretory system as teaching materials for 11th-grade high school students, 2) Assess the quality of biology E-LKPDs supported by virtual biology experiments via Online Labs (OLabs) on the excretory system as teaching materials developed for 11th-grade high school students, 3) To determine students’ responses to the developed E-LKPD. This study falls under the Research and Development (R&D) category and applies the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). This study is limited to the development stage. The quality of the E-LKPD was assessed by 1 subject matter expert, 1 media expert, 3 peer reviewers, and 1 biology teacher. A limited trial was conducted by 15 students from SMAN 6 Yogyakarta.. The instruments used included questionnaires for the subject matter expert, media expert, peer reviewers, biology teacher, and student responses. The data analysis techniques used were descriptive, qualitative, and quantitative. The research results indicate that: 1) The E-LKPD biology product supported by virtual biology experiments from Online Labs (OLabs) on the topic of the excretory system, developed as teaching material for 11th-grade high school students using the ADDIE model, was limited to the development stage; 2) The quality of the E-LKPD product, as assessed by experts, received scores of 95% from subject matter experts, 84.6% from media experts, 97.9% from peer reviewers, and 98.8% from biology teachers, 3) Student response to the ELKPD was very positive, with a 91.9% approval rate. Thus, the quality of the developed instructional materials falls into the “very good” category and is suitable for use in classroom learning processes.371.33 Media Pembelajaran2026-05-18UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
