Technology and science development couldn’t erase the traditional medication. Moreover the Indonesian economic condition caused modern medicine price became so expensive. That’s why one of alternative medication which should be done was increasing medical plant usage in society. Astiri oil from ginger plant filtrate as anti-bacterial substance able to inhibit the development of bacteri in mouth like S. Mutan. There were needed a research to prove it. The research aimed to find out the influence of ginger plant (Alpinia galanga) filtrate concentrate influence which was different in inhibiting Streptococcus mutan development also find out the most effective concentrate in inhibiting Streptococcus mutans bacterial development. The research used true experimental which was done at Bio-technology laboratory University of Muhammadiyah Malang which was done at Desember 2007. Population in this research was pure propagation of S. mutans bacterial from Medical Laboratory of Airlangga University of Surabaya with characteristic S. mutans has been cultured in Agar nutrient (NA). Sampling technique used in this research was Simple Random Sampling in simple random at S. mutans population which has suspended in NB media (Nutrien Both). Consentrate of ginger plant rhizome which was given in this research were 10%, 20%, 30%, 40%, 50 %.,dan 60%. The result showed that ginger plant rhizome filtrate didn’t has real influence to the development of Streptococcus mutans. The value of Fcount 0,0439 and Ftable 5 % was 2,77. since F count < Ftabel, so that Ho accepted and Hi was rejected, means that rhizome treatment with concentrates 10%, 20%, 30%, 40%, 50%, 60% had real influence to the development of Streptococcus mutans. Not only the influence of ginger plant to the Streptococcus mutans which caused by chemical contains in the ginger plant rhizome, that was concentrate level given. In each concentrate, there were small inhibition zone since the chemical contain in the ginger plant has been decreased since the concentrate level needed. In each concentrate, there were small inhibition zone, so that the anti-microbial ability decreased.
