Acidophyle bacteria including bacteria that can live in a relatively more acidic habitat. Enzymes that can be produced by acidophil bacteria other than amylase are proteases. Indonesia needs will be very high reaching 60% of total enzymes. Protease is very valuable for that it needs sources that can produce protease.In connection with this, it is necessary to isolate and use acidophilic protease producing bacteria. In this study using descriptive and development methods. In the results of the study, 4 isolates of protease-producing bacteria with a proteolytic index of 3.56 mm were obtained after the results of gram-negative bacteria with the genus aeromonas.The results of this study will create teaching materials in the form of booklets containing gram-negative bacteria, aeromonas. Besides that, the boolet was given pictures and information about the bacteria in the blue rice field. Based on the results of validity with several aspects, the booklet has an average validity value of 91.21% with very valid criteria.
