Ariesyady and Kusumah (2012) showed that Salmonella sp. and E.coli in the upper reaches of the Citarum River has exceeded the river's quality standards. According to Philippot et al., (2013), the loss of bacterial diversity will affect the soil nitrogen cycle. The next phase consisted in the isolation and quantification of pathogenic bacteria {Salmonella sp. and E.coli).
The last stage is the interaction test (Microcosm) according to Van Elsas et al. 2012) to determine the effect on sediment contamination by different chemical substances and E.coli on the NCB diversity index. Finally, the measured parameter was the NCB diversity index at days 0, 14, and 21 by the Shannon-Winner index in Eq. The largest number of E.coli was established in S5 (Nanjung), while the largest number of Salmonella sp.
The determination of the diversity index was performed at the beginning of the microcosm and acclimatization (HO) test, the last day of acclimation and inoculation E. After the acclimation process for 14 days, there was a slight decrease in the diversity index of NCB with a average of 0.01. Moreover, it can be concluded that the diversity index of NCBs was decreasing due to the higher level of sediment contamination.
Another factor that led to a decrease in the NCB diversity index was the reduction of nutrients in the sediment and the presence of secondary metabolites produced by the bacteria during the Microcosm test, which inhibited the growth of NCB. Furthermore, analysis of variance was also performed in the reduction data for the NCB diversity index on H14 and H21. ANOVA result of reduction data in the diversity index of NCB in Table 5 shows that the hypothesis testing of single and combined primary variables had a significance value.
In other words, the difference in sediment source and volume concentration of E.coli simultaneously had a significant effect on the reduction of the NCB diversity index. There were significant differences in the effect of pollution concentration on the reduced NCB diversity index. S3p4 treatment (sediment 3 Selacau, Batujajar and addition of E. coli 15%) resulted in the highest decline in diversity index at 0.27.
