The laboratory is one of the educational infrastructures, which can be used as a place for students to practice understanding concepts by conducting experiments and observations. Thus, the laboratory is an integral part that cannot be separated from teaching in the classroom. The existence of a laboratory is needed to provide direct experience from the application of theories received through laboratory/practical activities, to support teaching and learning activities.
In connection with the above, the role of the laboratory becomes very important, because the laboratory is the center of the teaching and learning process to conduct experiments, investigations, or research in lectures. Thus the laboratory has a function as a place for supporting activities from class activities, or vice versa class activities are supporting laboratory activities.
