Institutional Repository UIN Sunan Kalijaga YogyakartaPENGEMBANGAN LKPD BERBASIS CITIZEN SCIENCE BERBANTU APLIKASI INATURALIST PADA MATERI KEANEKARAGAMAN HAYATI SEBAGAI BAHAN AJAR BIOLOGI SISWA SMA/MANIM.: 22104070038Bunga Siti AysaauthorThis research is motivated by a biology learning process that is still teacher-centered and teaching materials that are limited to textbooks. These conditions cause students to experience difficulties in understanding biodiversity concepts, thus requiring more engaging alternative teaching materials. Furthermore, field observation activities conducted by students have been constrained by inefficient identification processes. Therefore, this study aims to produce a development design, as well as to determine the feasibility and practicality of a Citizen Science-based Student Worksheet (LKPD) assisted by the iNaturalist application on biodiversity material as a biology teaching material for high school (SMA/MA) students. The research method used is Research and Development (R&D) applying the 4D model, limited to the Development stage. The LKPD product was developed in a printed format measuring B5 (176×250 mm). Product feasibility was assessed by two material experts and two media experts, while practicality was evaluated by two biology teachers and 24 students using a 5-point Likert scale questionnaire. The data analysis results showed validity and reliability levels in the very high category. The feasibility test from the material experts obtained a validity score of 0.911 and a reliability of 0.952, while the media experts scored a validity of 0.874 and a reliability of 0.932. Meanwhile, the practicality test from the biology teachers obtained a validity score of 0.910 and a reliability of 0.857, and the student responses yielded a validity of 0.840 and a reliability of 0.970. Based on these findings, it can be concluded that the developed Citizen Science-based LKPD assisted by the iNaturalist application falls into the highly feasible and highly practical categories for use as a learning guide in high school biology education.371.33 Media Pembelajaran2026-05-11UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
