Recycle of Semarang City Liquid Waste with “Reuse” Consortium of Mangrove Probiotic Bacteria Treatment

Statement of the Problem: Reuse bioactivator liquid composter had been produced for liquid waste treatment consist of four probiotic bacteria function as pathogenic antibacteria-agent. Whereas the use of four consortium probiotic bacteria will have a better pathogenic antibacterial activity than only one type. The purpose of the research is to process liquid waste and produce clean water by means of eliminating the number of pathogenic bacteria using a 'Reuse' probiotic consortium. Further step is pathogenic bacteria count after treatment and phyto-chemical analysis of the 'reuse' product. Methodology & Theoretical Orientation: Reused liquid is added to each waste water sample in 10 and 20 ppm concentration. Observation includes: resulting odor, microbial development, absorbance rate, identification of pathogenic bacteria by morphology, and phytochemical screening of the resulting compounds. The results show that sample with 20 ppm reused water is odorless, with lowered density of pathogenic bacteria population from 12 x 10� cell/mL to 3 x 10� cell/mL, and lowered absorbance rate from 0.625 nm to 0.225 nm. Staphylococcus Aureus is found to be the most prevalent pathogenic bacteria in the waste water. The microbial consortium is found to produce alkaloid, tannin, and steroid. The formation of inhibition zones is the result of microbial consortium activity against the pathogenic bacteria. Conclusion & Significance: Applied technology of 'Reuse' mangrove probiotic bacteria consortium had significantly be able in recycling Semarang city liquid waste to produce clean water.
