Abstract

ABSTACT

The dairy industry is increasingly producing waste that is still not properly treated, such as sludge from wastewater treatment plants. Sludge that is left in the open will be a potential source of pollutants. Sludge creates an unpleasant odor and if it is carried into the river, it will increase the level of pollutants in the water.

The purpose of this study was to determine the potential use of sludge in the dairy industry as a raw material for compost with a mixture of sawdust and goat dung as a mixture and the addition of MOL as a bioactivator, with a mixture variation of 0.5: 3: 1 and 0.5: 3: 2 with the addition of 500 ml of each variation.

The results obtained indicate that the mixture of milk sludge, sawdust and goat manure with variation of 0.5: 3: 1 shows that the C / N ratio after composting is 18.22, these results have met the quality standards of SNI 19-7030-2004 which is equal to 10 - 20, and the variation of 0.5: 3: 1 shows the content of the C / N ratio of 23.45, this result when compared with the quality standard of SNI 19-7030-2004 exceeds the maximum level of the C / N ratio. In general, the composting variation of 0.5: 3: 1 is better than the variation of 0.5: 3: 2
