Recently, more industrial activities were developed like household industries. Laundry liquid waste is a source of pollution which it can decreasely the equality of the 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 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. The method used was fermentation with bioactivator EM4 and molasses as nutrients, and the fermentation results were tested at the Laboratory of BARISTAND Banda Aceh. Parameters tested were pH, carbon, nitrogen, phosphate, and potassium. The results showed that at a concentration of EM 20 ml, pH levels were 4,7, carbon organic levels were 3.250%, nitrogen levels were 0.040%, phosphate levels were 0.014% and potassium levels were 1.489%, the result of these concentration were better than other variations in concentration EM4 like 40, 60, 80 and 100 ml for increasing nutrients levels in laundry liquid waste.

Oil waste that enters the soil will cause damage to the soil. 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.

This study aims to examine the effect of fermenting cow rumen waste and yeast on biogas stove performance. This study uses a quantitative approach with experimental methods starting with the stages of designing, assembling, testing the design results, observing and processing data. In this study, to get good biogas results, it was carried out in a 2:1 ratio pf water mixed with yeast and cow’s rumen. The fermantation process takes 8 to 31 days, during which the cow’s rumen needs to be stirred regularly to prevent solid particles from setting at the bottom of the digester.
