Application of cooperative learning model through visual video with demonstration method in microbiology course

Microbiology is the study of living organisms that are very small in size and cannot be seen in plain view. At present, the student from the chemistry department who conducting Microbiology research, such as antibacterial and antifungal. In addition, many students doing industrial work, especially in the food and cosmetics industry related to microbiology. Lecture strategy contains a verbal presentation of ideas, facts, concepts and generalisations. The practice of this method is that of spoon-feeding the learners with facts or information students become confused and do not understand the material presented. The students become inactive because students only listen to explanations from the lecturer. Low student learning outcomes become a problem that must be considered by lecturers. One way to improve student learning outcomes is to use visualisation media or direct practice with a demonstration method of material being learned. The results obtained are planned for 3 (three) lecture materials in the classroom with students, for the learning outcomes for middle and final test of 58.05 and 66.94. In this control class, students who get mastery grades in learning or who score above the minimum completion criteria 70.00 namely of 22 students out of 55 students with a percentage of 40%, the average classical value of 67.43. While the completeness value for the class that uses the treatment of visual video media and demonstration methods obtained the value of learning outcomes middle and final test of 74.19 and 70.32 with values above the minimum completeness criteria 70.00, namely of 26 students out of 31 students with a percentage of 83.87%, the average classical value of 73.70.
