Abstract
Critical thinking skills are competencies that are expected to be possessed by every student in 21st century learning. One of the efforts that can be made to improve students' critical thinking skills is to apply the flipped classroom learning model. This study aims to determine the effect of students' critical thinking skills through the application of the blended learning model of the flipped classroom. The research approach used is quantitative with a quasi-experimental type of research, the research design used is pretest-posttest non-equivalent control group design. Sampling used a total sampling technique from the entire population of 102 students of class XI IPA at SMAN 1 Peulimbang. The instrument used to measure critical thinking skills is in the form of essay questions accompanied by an assessment rubric. Data on critical thinking skills were analyzed by parametric statistics using the independent sample t test. The results showed that the value of < 0.05, then there was an effect of students' critical thinking skills after the application of the blended learning model of the flipped classroom on the respiratory system material

Summary
Organ system is one of the learning topics in class XI in the even semester. One of them discusses the respiratory system with basic competence analyzing the relationship between the structure of the organs that make up the respiratory system in relation to bioprocesses and functional disorders that can occur in the respiratory system (Basic Competencies 3.8), presenting the results of an analysis of the effect of air pollution on abnormalities in the structure and function of the respiratory system function of human respiratory organs based on a literature study (Basic Competencies 4.8), with several learning objectives that must be achieved.Achievement of the learning objectives of the respiratory system material in SMA Negeri 1 Peulimbang, Bireuen Regencynot achieved optimally, Based on the data obtained from initial observations, it is known that the learning outcomes of students in SMA Negeri 1 Peulimbang, Bireuen Regency in biology lessons on the respiratory system material are low learning outcomes students can be seen from the average initial test scores of students on the respiratory system material that is still below the minimum completeness criteria, which is 60% of students with a minimum completeness criteria of 75. Based on the results of interviews with one of the biology teachers at SMA Negeri 1 Peulimbang, Bireuen Regency, information was obtained that students still did not understand the material of the respiratory system. This is because the learning process is still centered on the teacher while students only listen and pay attention to the teacher's explanation. Research on critical thinking skills has been carried out by several previous researchers, As stated in the 21st century learning objectives, critical thinking is a competency that is expected to be possessed by every student.
