Abstract
ABSTRAK Penguasaan konsep merupakan aspek penting dalam proses pembelajaran sains, khususnya biologi. Namun, dalam praktiknya, masih banyak peserta didik yang mengalami kesulitan dalam memahami konsep abstrak seperti keanekaragaman hayati, yang seringkali hanya diajarkan secara teoritis tanpa pengalaman konkret. Penelitian ini menggunakan metode quasi eksperimen dengan desain pretest-posttest control group. Populasi dalam penelitian ini adalah peserta didik kelas X di salah satu SMA negeri di Bandar lampung. Sampel penelitian terdiri dari dua kelas yang dipilih secara purposif, yaitu satu kelas sebagai kelompok eksperimen(n=35) dan satu kelas sebagai kelompok kontrol(n=35). Kelompok eksperimen mendapatkan pembelajaran menggunakan model Discovery Learning berbasis benda nyata, sedangkan kelompok kontrol menggunakan metode ceramah dan diskusi tanpa media konkret. Instrumen pengumpulan data berupa tes penguasaan konsep berbentuk pilihan ganda beralasan, serta lembar observasi aktivitas belajar.. Kesimpulan dari penelitian ini adalah bahwa penerapan model Discovery Learning berbasis benda nyata efektif dalam meningkatkan penguasaan konsep peserta didik pada materi keanekaragaman hayati. Kata kunci: Penguasaan konsep, keanekaragaman hayati, discovery learning, benda nyata, pembelajaran biologi. iii ABSTRACT Mastery of concepts is an important aspect in the science learning process, especially biology. However, in practice, many students still experience difficulties in understanding abstract concepts such as biodiversity, which are often only taught theoretically without concrete experience. This research uses a quasi-experimental method with a pretest posttest control group design. The population in this study were class X students at one of the state high schools in Bandar Lampung. The research sample consisted of two classes selected purposively, namely one class as the experimental group (n=35) and one class as the control group (n=35). The experimental group received learning using the Discovery Learning model based on real objects, while the control group used lecture and discussion methods without concrete media. The data collection instrument is a concept mastery test in the form of reasoned multiple choice, as well as a learning activity observation sheet. The conclusion of this research is that the application of the Discovery Learning model based on real objects is effective in increasing students' mastery of concepts in biodiversity material. Keywords: Concept mastery, biodiversity, discovery learning, real objects, biology learning.
