Therefore, only of the Percentage Kill method, the results of the fifth minute is able to meet the specified standard. Percentage Kill formula. Based on the calculations, the final results of the Percentage Kill method during minutes 1, 2, and 5 respectively are 93. 14% and 96. for E. coli and 27%, 83. 15%, 94. 188% respectively for S. According to these results. It can be stated that the higher percentage kill results, thus showing the eradication level of E. coli is bigger. The Percentage Kill results can be exceeded Ou 90%. From the first minute, percentage level . bove 90%), hence we can state that it has already given benefit in terms of hinder the growth of Meanwhile for S. findings in the first and second minute Discussion This experiment presence of antimicrobial efficacy of M. oleifera to suppress the growth of E. and S. Supported by the smooth growth of colony which is given treatment in comparison to the higher growth of colony found in control. From the average colony number of these repetitions, it can be stated that the extract of M. oleifera can eradicate E. The hypothesis of the above mentioned notion is due to the antiseptic properties of M. extract that can slow the growth rate of It can be explained by several possible mechanisms. The first one is that the phytoconstituents from the M. oleifera itself such as Isothiocyanate and it derivates, for instance Allyl isothiocyanate (AITC) as it will provide The Indonesian Jounal Of Infectious Disease | Volume 8 No. effects towards the bacterial membrane a result, the metabolism of bacteria is 12,13 bacteria by inhibiting the activity of Tannin thioredoxin which is a key role enzyme for its metabolism. activity, its action is dependent on viral Moreover, aqueous extract shows activity and MIC results that are effective towards capacity to assault human cells being Gram negative bacteria such as E. due to the active components of mechanisms lead to the decrease of E. Tannins. Phenol Alkaloids. All Polyphenols that existed accumulate on contributing to the probability of M. bacteriaAos increased hydrophobicity and elimination of Escherichia coli and even eventually an increase in bacterial may acts as an antiviral, indicated by growth inhibition percentage. On the the significant difference on the colony results based on time contact and Tannins' efficacy is explained by their capacity to repetition in comparison to control. 14,15 penetrate through the bacterial cell wall Previous research by Dima LR et up to the interior membrane, causing interference with the cell's metabolism Manado, in 2016 stated that different and, as a result, its death. Tannic acid concentration of M. oleifera in 5%, 10%, 20%, 40% and 80% have shown a surfaces since it acts as the inhibitor of potent antibacterial result, shown when NorA efflux pump which is considered at the highest concentration percentage which is 80% can results the highest antibacterial activity. Thus, bacterial cell MIC zone diameter of 24. 00 mm in E. death comes from a loss of adherence coli, and the smallest diameter can be to the surface. Tannic acid also inhibits found in the lowest concentration which the absorption of sugar and amino is 12mm from 5% concentration. The smallest concentration has even shown Tannins are multidentate a significant result as antibacterial. ligands that may bind to proteins Combining the highest percentage and number of contact time might eradicate interactions and hydrogen bonding. a higher number of E. coli growth. 16,17 Sam Ratulangi University. Based on their research we continued The Indonesian Jounal Of Infectious Disease | Volume 8 No. with antiseptic potency test using the antimicrobial efficacy is associated with percentage kill method and the result longer duration of contact. showed promising. Furthermore. On the comparison of contact time affected by the presence of active towards the growth of E. coli, there is an average number of colony growth on contained in M. oleifera which minute 1, 2 and 5 minutes which are extracted by certain solvents including 11, 8. 33 and 3. 33 respectively. The aquadest and ethanol. The extraction of extract of M. oleifera has antibacterial properties from the Percentage Kill generate polyphenol and flavonoid, results on minute 1, 2 and 5 with while the involvement of aquadest in extraction produce tannin, saponin, minute contact time using extract of M. Flavonoid takes part in generating oleifera has already given a prominent antimicrobial activity in M. and effective results and five minutes of through the disruption of bacterial cell wall and cytoplasm which inhibit the cell highest eradication number of E. division process. Supported by the ability of flavonoid to form a complex Meanwhile the result derived from with extracellular proteins and bacterial the Percentage Kill method of S. cell wall. 18,19 Another phytochemical in pyogenes showed that the influence of oleifera is alkaloid which possess oleifera extract can already be bacterial DNA disturbing characteristics identified within the first 1 minute. Although the outcome of 73. 27% and functioning in directing nucleotide to 15% found in the first and second single strand DNA. This interruption of minute respectively still does not fulfill interference of bacterial cell division effective antimicrobial which is >90%. and consequently the normal structure However, a notable improvement of the of the bacteria along with suppression plantAos antimicrobial action is identified of protein synthesis which takes part in in the fifth minute demonstrated by a the metabolism and construction of result of 94. This information bacterial cell wall. In addition to the signify that the increase of M.
