These measurements were performed at t = 0 hours and t = 4 hours to follow the trend of decrease in dissolved COD value. The performance of the bacteria's waste breakdown was indicated by the COD/VSSb ratio, the organic load ratio between the reduction of dissolved COD and VSS bacteria. The ratio between the value of the dissolved COD and bacteria VSS showed the performance of the treatment process, when the ratio is smaller, the treatment progresses worse.
In this experiment using C/T U/C Silver paint by varying the composition percentage, the highest ratio of the COD/VSSb was obtained for the variation number 34 with the value of 21.65 mg O2/L per mg VSS/L. Meanwhile, in the variation of the species of bacteria, the ratio of the COD/VSSb that gave the highest value was variation number 63 with a value of 16.77 mg O2/L per mg VSS/L. Furthermore, with the optimum composition of the consortium assay we could obtain that waste treatment by a consortium of five bacteria was more effective than other bacterial species variation.
This means that each of the five components of the bacteria has a target of each paint component according to its enzymes. The highest COD/VSSb ratio for Axis Gray paint was obtained by varying the percentage of the composition by variation number 12 which gave a value of 23.03 mg O2/L per mg VSS/L. It shows that the variation of the number 12 was more effective than the variation of the number 62.
COD/VSSb value of Phantom Silver paint for each variation (a) Composition Percentage Variation (b) Bacteria Species Variation The COD/VSSb ratio with percentage variation compositions could be seen to have the highest value of 16.82 mg O2/L per mg VSS/L in variant number 35. In contrast, the ratio of COD/VSSb with variations in the type of bacteria has the highest value of 13.35 mg O2/L per mg VSS/L in variant number 64. The results showed that the variation of the number 35 was more effective than the variation of the number 64.
From Figure 4, it can be seen that the ratio of COD/VSSb of the composition percentage variation gave the highest value of 24.04 mg O2/L per mg VSS/L for the variation number 20. Meanwhile, the ratio of COD/ VSSb of the variation in the bacterial type has the highest value of 20.97 mg O2/L per mg VSS/L at the variation number 60. The result showed that the variation of the number 20 was more effective than the variation of the number 60.
Thus, the optimal composition of the consortium in four suits generally has the same result as the chosen optimal variation that gave. For example, in Axis Gray and C/T U/C Silver, the paint has differences between the percentage of additives used and the use of resin as a material component of the paint.
