Virtual Experiment Buffer+ dikembangkan oleh Aulia (2022). Penelitian ini menggunakan metode pre experimental. Subjek penelitian terdiri atas 32 peserta didik kelas XI di salah satu SMA di Kota Cimahi. Tahapan penelitian meliputi analisis karakteristik virtual experiment Buffer+, analisis model pembelajaran untuk digunakan dalam pembelajaran, dan pelaksanaan pembelajaran berbantuan virtual experiment Buffer+ untuk mengetahui peranan Buffer+ dalam memfasiltasi kemampuan berpikir kritis peserta didik. Aspek keterlaksanaan pembelajaran diukur melalui lembar observasi dan penilaian Lembar Kerja Peserta Didik (LKPD), sedangkan kemampuan berpikir kritis diukur melalui tes uraian dalam LKPD. Karakteristik virtual experiment Buffer+ merupakan media yang mampu memvisualisasikan alat, prosedur, dan hasil eksperimen sesungguhnya. Model pembelajaran yang sesuai dengan karakteristik virtual experiment adalah model inkuiri terbimbing. Penerapan model inkuiri terbimbing terlaksana dan virtual experiment dapat berperan memfasiltasi kemampuan berpikir kritis peserta didik. Sebanyak 19 peserta didik memiliki kemampuan berpikir dalam kategori sangat tinggi, 4 peserta didik pada kategori tinggi, 8 peserta didik pada kategori sedang, dan 1 peserta didik pada kategori rendah. Hasi uji chi-square menunjukkan bahwa kemampuan berpikir kritis peserta didik sama dan cenderung pada kategori sangat tinggi. This study aims to examine the role of the Buffer+ virtual experiment in facilitating students' critical thinking skills. The Buffer+ Virtual Experiment was developed by Aulia (2022). This study used a pre-experimental method. The research subjects consisted of 32 eleventh-grade students at a high school in Cimahi City. The research stages include analyzing the characteristics of the Buffer+ virtual experiment, analyzing the learning model for use in learning, and implementing learning assisted by the Buffer+ virtual experiment to determine the role of Buffer+ in facilitating students' critical thinking skills. The aspect of learning implementation is explained through observation sheets and assessments of Student Worksheets (LKPD), while critical thinking skills are measured through descriptive tests in the LKPD. The characteristics of the Buffer+ Virtual Experiment are media that are able to visualize the tools, procedures, and results of real experiments. The learning model that is appropriate to the characteristics of virtual experiments is the guided inquiry model. The implementation of the guided inquiry model was implemented and the virtual experiment can play a role in facilitating students' critical thinking skills. A total of 19 students have thinking skills in the very high category, 4 students in the high category, 8 students in the medium category, and 1 student in the low category. The results of the chi square test show that students' critical thinking abilities are the same and tend to be in the very high category. date: 2025-08-19 date_type: published institution: Universitas Pendidikan Indonesia department: KODEPRODI84204#Pendidikan Kimia_S1 thesis_type: other thesis_name: other official_url: https://repository.upi.edu/ related_url_url: https://perpustakaan.upi.edu/ related_url_type: org citation: Shopiy Nabilah Hidayat, - and Gun Gun Gumilar, - and Ijang Rohman, - (2025) PERANAN VIRTUAL EXPERIMENT BUFFER+ DALAM PEMBELAJARAN UNTUK MEMFASILITASI KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK PADA MATERI LARUTAN PENYANGGA.
