Aloe vera gel has antibacterial properties. The content of compounds in aloe is saponins, anthraquinones, tannins, aloin, and acemannan. the potential as an edible coating for food products. Processing carried out goes through a heating process that does think to damage gel. This study aims determine activity formulated on S. aureus, mutans, E. coli K. pneumoniae bacteria. research method used disc diffusion method. Based test results, pure larger inhibition zone diameter than processed into coating. Diameter coli, respectively 10.966 ± 0.573 mm; 11.806 0.215 10,860 0.675 mm, 10.686 0.081 mm. with ability, namely at concentration 100%, which anti zone's mutans bacteria, respectively. 10,470 0.213 10,673 0.127 10,113 0.040 9.676 0.604
