Based on the results of the hypothetical test analysis obtained t hit > t daf (1.67), then accept. Hi means that there is an influence on the use of audiovisual learning media on critical thinking ability in human digestive system materials in grade VIII students of SMP Negeri 1 And SMP Negeri 2 Sindang Indramayu Regency. From the calculation of t test above obtained t count = 4,957 while t table at the level of trust 95% (significance 5%) with dk numerator is 1.70. Because t count (4,957) > t table (1,70) Hi accepted means there is an influence on the use of audiovisual learning media on self-efficacy in human digestive system materials in grade VIII students smp negeri 1 Filled And SMP Negeri 2 Sindang Indramayu. The result of this study is a description of the efficacy of students of grade VIII SMP Negeri 1 Filled And SMP Negeri 2 Sindang Indramayu Regency, by using audiovisual media learning system in human digestive system materials belongs to high category. There is an influence of audiovisual media learning system on self-efficacy on human digestive system materials in students VIII SMP Negeri 1 Filled And SMP Negeri 2 Sindang Indramayu. Keywords: Audio Visual Media Learning System Self-Efficacy And Critical Thinking Ability INTRODUCTION Teaching and Learning activities are the process of interaction between learners and the environment with the achievement of behavioral changes that include the cognitive, affective and psychomotor spheres have not achieved something expected. The process of biology learning only demands and emphasizes on the achievement of student learning outcomes in the form of cognitive realms with the acquisition of grades after carrying out learning, thus leading to the undevelopment of students' thinking abilities, especially students' critical thinking skills in learning and understanding the subject matter. Critical thinking is applying rational, high thinking activities, which include analyzing, synthesizing, recognizing problems and solving them, concluding, and ISSN : P-2720-9938 e-2721-5202
