Abstract

Skin infection is able to be caused by pathogenic bacteria like Staphylococcus aureus [1]. This bacteria is a Gram (+) bacterium having habitat in noses, respiratory tract and skin. Therapy used to reduce this bacteria is antimicrobial drug or antibiotic. But, if given in long time and uncertain concentration, so this bacteria will form drug resistance [2] . New application of medical technologies should be developed for reducing drug-resistance bacteria. One of them is photodynamic inactivation (PDI).Photodynamic inactivation has been developed in reducing colony bacteria like Staphylococcus aureus. Chlorophyll has been known green pigment and could be as photosensitizer. This research aimed to reduce colony using blue laser diode, chlorophyll and oxygen. Chlorophyll was extract leaves amboyna wood (Pterocarpus indicus) and Oxygen source is obtained by gas cylinder. Treatment of sample was done in complete dark room. Group sample is laser group, laser and adding chlorophyll group, laser and adding oxygen group and laser and adding chlorophyll and oxygen. Output power of laser was used 16,97 mW. Time exposure was 20 s, 40 s, 60s and 80s. The treatment were divided to four group, i.e. laser group, laser and adding chlorophyll group, laser and adding oxygen and laser and adding chlorophyll and oxygen. This result showed that the most of percentage decrease was laser and adding chlorophyll group in time exposure 40 s about 17,96 %. The other group would be described in this paper.
