Water resource management in a dairy farming environment is very important. Properly managing dairy farm wastewater and converting it into products that can increase soil fertility is needed to prevent pollution of water sources. Pollution can change the physical, chemical and biological properties of water, resulting in eutrophication. The aim of this research is to find out how livestock activities cause pollution to water sources and whether aerobic fermentation treatment of liquid waste can produce products that are beneficial to the agricultural environment. The water resources management study was carried out in an exploratory manner, water samples were taken from several points, namely household, domestic and river, followed by a liquid waste processing experiment using a completely randomized design, samples were obtained from holding ponds, treated with 4% Molasses, a starter consisting of from silage leachate 4%, and fish meal 1-5% fermentation was carried out aerobically for 3 weeks, with two repetitions. The results of the research obtained a soil conditioner product with an organic carbon content of close to 10, pH according to standard, heavy metal and micronutrient content below standard, biological results did not find E.coli bacteria. and Salmonella bacteria. |
