INTRODUCTION The Indonesian government also understands the importance of education for its people. Since the country's establishment, education has been listed among the nation's primary goals, which is reflected in the concept of educating the nation's youth. This is not something that happened by When Indonesia became an independent country, the government committed to the compulsory education program to enable people in Indonesia to learn and improve the quality of education (Sitompul, 2. Quality education not only provides knowledge but also trains us to be critical thinkers, as students need to analyze questions and dig deeper into everything they learn. Not only does the Government receive information in this manner, but it also emphasizes education in the form of logical and critical thinking skills, rather than just memorization. Therefore, as the next generation of the nation, students must continue to develop their critical thinking skills so that they can face today's challenges and find solutions to the problems that occur around them. Based on this description, a learning model is needed that supports the development of students' critical thinking skills. The learning model that can develop students' thinking skills is ProblemBased Learning (PBL) (Jazilatul Fitriyyah & Sri Hartati Wulandari, 2. In Indonesia, student learning outcomes remain low, suggesting that the quality of education at schools is also subpar. This can be seen from the initial data on student assignment grades and daily tests, which are still below the KKM. The Problem-Based Learning model is one of the learning models that can help students develop their critical thinking skills to solve problems. Students who possess the ability to think critically will be more effective in making decisions, processing information, and overcoming existing problems or issues (Rahman et al. , 2. On the other hand. Aprilianingrum & Wardani . also explain that Problem-Based Learning is a model designed to provide opportunities for students to gain learning experiences in organizing, researching, and solving complex everyday PBL offers ample space for students to develop higher-order thinking skills, including critical, creative, and collaborative thinking. Many factors affect learning outcomes, one of which is the learning model used. The ProblemBased Learning model is a cooperative learning approach that requires students to be active and motivated, enabling them to support and help one another in mastering the subject matter being studied (Djonomiarjo, 2. In line with his research Setiaji et al. , . He explained that, in addition to students' thinking ability, there are also factors that greatly affect student learning outcomes, namely learning independence. Independent students will be able to master the material and solve the problems they encounter. Independent learning requires students to be active and not dependent on teachers, but it also explains why this is the case. Yanuarti Soima et al. , . PBL is a learning model where students gain knowledge from the learning materials presented, by using reallife problems and daily life examples as a context for learning to think critically and solve problems. Critical thinking skills are essential for current and future students. Critical thinking habits should be developed from an early age, enabling students to navigate changing situations and life challenges that continue to emerge. Essential skills of thinking train students to develop ideas and decisions from various perspectives in detail, meticulously, thoroughly, and logically. Learning in schools should enable and train students to explore critical thinking abilities (Prihono & Khasanah. And the principle of PBL is to use Hardiantiningsih et al. , . Real-world problems help deepen students' understanding, develop their higher-level thinking skills, and improve their problemsolving skills. Critical thinking is an essential skill for students in today's information age. This critical thinking ability allows individuals to analyze information, evaluate arguments, and make rational In the context of education, critical thinking is not limited to memorizing facts, but also involves a deeper understanding of a concept. So that later students are expected to be able to solve problems that occur creatively. One example of Problem-Based Learning (PBL) in effective learning, where students are empowered to develop critical thinking skills, is the Problem-Based Learning Based on the results of the literature review, it is evident that students tend to work together in completing tasks assigned by the teacher, resulting in minimal development of their critical thinking skills, which makes them dependent on other students to complete the task. In addition, traditional learning methods, such as lectures and memorization, which are still prevalent, tend to be less effective in developing students' critical thinking and problem-solving skills. Therefore marhamah & Hajaroh. , . It is explained that the general purpose of the Problem-Based Learning model is to encourage students to be more courageous and creative in imagining. With their imagination, students are guided to create discoveries, both in the form of existing improvements and new ideas. The Problem-Based Learning model is expected to change students' mindsets, enabling them to solve tasks in the form of problems critically. Based on the introduction above, the purpose of this study is to determine whether the Problem-Based Learning (PBL) learning model influences students' critical METHOD To study and analyze various literature and research related to the topics discussed in this article, we employ the literature review method, also known as a literature review. This method aims to answer the researcher's questions specifically through a series of processes, including identification, analysis, synthesis, assessment & comparison of all relevant literature that informs the formulation of the feud or topic observed in the research (Purwita Sari et al. , 2.

Discussion Based on the results of literature reviews from several journals, it was found that there is a significant relationship between the application of the Problem-Based Learning model and the improvement of students' critical thinking skills. Problem-Based Learning involves students in the learning process by solving real-world problems, which encourages them to think more deeply and According to Muhzemmil et al. , . Problem-Based Learning (PBL) is problem-based learning in solving problems that occur in an environment and as a basis for achieving knowledge/and understanding concepts, with critical thinking skills, so that the application of the Problem-Based Learning (PBL) model is expected to grow and improve learning outcomes and student engagement in learning activities. Meanwhile, in my opinion. Marisa . suggests that PBL is a learning model that encourages students to become more focused on learning. Problems are presented at the beginning of learning to help students develop critical thinking skills and allow them to investigate and research issues throughout their learning in real-life situations. Furthermore, the Problem-Based Learning (PBL) learning model can be utilized to stimulate student engagement and enhance students' learning outcomes (Wahyudiyantoro et al. , 2. The Problem-Based Learning model has made a significant contribution to improving students' critical thinking skills. Through the learning process, the steps contained in this model can help students enhance their abilities. The presentation of problems as the focus of learning is one of the characteristics of this model. the problems used must be appropriate to students and contextual. This is consistent with students' cognitive development in using high-level logic to solve problems or solve student problems. (Rosida & Nuvitalia, 2. The opinion that Problem supports this research Fitria et al. , . Based Learning (PBL) is considered one of the most effective approaches because this model focuses on problem-solving and actively involves students throughout the learning process. As a result, this PBL model enhances student engagement and their understanding of the conceptual material required to solve problems. To improve students' critical thinking skills, teachers can utilize problem-based learning methods or models. The problem-based learning model refers to a teaching and learning concept that utilizes learning methods centered on real-world problems, allowing students to analyze and evaluate issues in a systematic and directed manner (Novia et al. , 2. This opinion is in line with Salamah Anisa Amalia & Cahyaningsih, . The opinion that critical thinking is the activity of thinking carefully and using measures and standards to determine the solution to a problem. Critical thinking skills are beneficial for students in facing various issues in their lives. therefore, continuous training is needed to train students' critical thinking skills, starting from basic education (Pamungkas & Wantoro, 2. The indicators of critical thinking, according to Zalukhu et al. , . Include interpretation, analysis, evaluation, and conclusion. Students with strong critical thinking skills will be better prepared to consider various perspectives and organize ideas when making decisions. The Problem-Based Learning model can increase student motivation by providing challenges and creating a fun atmosphere through a process that aims to achieve understanding in problemsolving. Additionally, the Problem-Based Learning model has a positive impact on students' critical thinking skills. This is proven when students are given the treatment of the Problem-Based Learning teaching model with the support of concrete media. students will be more willing to ask questions and express their opinions. And when teachers give assignments, they are also able to provide explanations and reasons relevant to the problem (Rahayu et al. , 2. This is in line with the research carried out, which explains that student learning outcomes are also influenced by Said & Azhar, . External factors, such as the subject matter presented in the form of cases or problems through the problem-based learning model (PBL), also affect student learning outcomes. Additionally, internal factors, including strong encouragement for students to solve problems with their classmates, also impact student learning outcomes. The number of articles used as material for analysis in this study is still limited. hopefully, the next researcher can increase and enrich the number of articles discussed and analyzed, making the influence of this PBL model on students' critical thinking skills more visible. Referring to the results and findings of this study, it is hoped that it will be able to provide understanding and learning to education actors in general and teachers in particular, to be able to apply this PBL model in classroom learning, so that learning can attract interest and be effective in improving students' critical thinking so that in the future the quality of Indonesian education will be better (Rahmadana et al. CONCLUSION The results of this study show that the application of the Problem-Based Learning (PBL) model has a significant impact on the development of students' critical thinking skills. This learning model emphasizes collaborative problem-solving in the real world and can encourage students to be more active in analyzing, evaluating, and synthesizing information. By engaging students in situations that require problem-solving. PBL fosters the development of critical thinking skills essential for navigating future challenges in life and the workplace. Therefore, teachers who implement PBL in their classrooms must design challenging and relevant assignments and create a learning environment that supports interaction and deep reflection, enabling students to improve their critical thinking REFERENCES
