Bioremediation is an alternative to hazardous waste treatment which is relatively more economical, easy and environmentally friendly. This technology utilizes microbial activity to treat polluted soil. Cow dung is an organic material that contains many microbes and also contains good nutrition for microbial growth. Cow dung contains several microorganisms such as bacteria (Bacillus sp, Lactobacillus sp and Corynebacterium sp), fungi (Trichoderma sp and Aspergillus sp), protozoan and yeast species (Candida sp and Saccharomyces sp). Cow dung in this study acts as a bioactivator and a source of nutrients for microbes in degrading Total Petroleum Hydrocarbon (TPH) in oil-contaminated soil. This study aims to determine the effect of adding cow dung on bioremediation of oil-contaminated soil. This study consisted of six (6) treatments, namely the concentration of cow dung with variations in concentrations of 0 gr, 20 gr, 40 gr, 60 gr, 80 gr, and 100 gr on each soil of 300 gr and processing time for 30 days and analyzed 2 times a day. In this study, measurements of pH and TPH values were carried out. The results of the analysis showed that the addition of cow dung with a concentration of 100 gr on 300 gr of soil was able to reduce the TPH value from 3.6% to 0.2%, with the effectiveness of reducing TPH by 86.66% within 30 days. Based on the results of the analysis using the Simple Linear Regression Test, it was stated that the bioremediation time and the addition of the concentration of cow dung had an effect on the decrease in the TPH value.","PeriodicalId":223573,"journal":{"name":"Lingkar : Journal of Environmental Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Which one of it is household industries is laundry business. Laundry business generate liquid waste from washing clothes activities with using detergent. Laundry liquid waste is a source of pollution which it can decreasely the equality of the environment. A large amount of laundry liquid waste is discarded into environment. Therefore, it can be used as a liquid fertilizer, one of the pollutants within laundry liquid waste is phosphate and it derived from Sodium TripolyPhosphate (STPP) which is one of the ingredients in detergents and as a second most important element after surfactants. The purpose of this study was to determine the whether effect of the utilization of the laundry liquid waste as liquid fertilizer on the C/N ratio and to find out the quality of liquid fertilizer used meet the quality standards of liquid fertilizer in the Peraturan Menteri Pertanian No. 70 of 2011 concerning Fertilizers, Biological Fertilizers and Soil Improvements. The method used was fermentation with the addition of bioactivator EM4 and molasses as nutrients, and the fermentation results were tested at the Laboratory Balai Riset Dan Standardisasi Industri (BARISTAND) Banda Aceh.

Trembesi is the most effective plant in adsorbing pollutant carbon in the air. Activated charcoal is the carbon that has better absorption of cations, anions and the molecules of organic and inorganic compounds.
