Antibactery test of dragon scale leaves (Drymoglossum piloselloides) patientaries on the hamble zone of Propionibacterium acnes

Abstract

Research on the benefits of the starch essence of dragon scale leaves (Drymoglossum piloselloides) against anti-bacterial P.acnes has not yet been conducted. The use of dragon's scales as an anti-bacterial on acne is intended to develop a new type of anti-bacterial that has minimal side effects against Propionibacterium acnes bacteria and to overcome resistance problems arising from the use of antibiotic drugs. This research uses laboratory experimental method with quantitative research type and the design used in the research is Post Test Only Control Group Design. The parameters measured were the antibacterial power of Drymoglossum piloselloides leaf starch juice against Propionibacterium acnes microbiologically by using the disc paper method, then the inhibition zone was measured using a caliper with an accuracy of 0.01 mm. The results of measuring the diameter of the inhibition zone of dragon scale leaf starch juice (Drymoglossum piloselloides) against Propionibacterium acnes inhibition zone, obtained the average diameter of the inhibition zone at a concentration of 40% of 1.26 mm with a weak category, at a concentration of 50% of 1.94 mm with a weak category, at a concentration of 60% of 2.8 mm with a weak category, at a concentration of 70% of 3.36 mm with a weak category, at a concentration of 80% of 3.94 mm with a weak category and in the positive control using Chloramphenicol get an average inhibition zone diameter of 8.36 mm with a moderate category
