This type of research is experimental research. The stem bajakah Tampala looks like it wastaken from the inland forest in Garung Village, Jabiren District, Pulang Pisau Regency, Central Kalimantan. The sample of this study was 70% ethanol extract of bajakah tampala stems obtained by maceration. Extract payment of antibacterial activity using a concentration of 3.12%; 6.25%; 12.5%; 25% and 50%. The positive control used is ampicillin 0.01 mg/ml and negative control using distilled water. Tests are carried out by the well method. The tested data were analyzed statistically by the One-Way ANOVA test method. The results of the study showed that the ethanol extract bajakah tampala could inhibit the growth of E. coli bacteria. The biggest inhibition of E. coli bacteria at a concentration of 50% with an average inhibition diameter of 20.32 mm. included in the category of very strong.
