The aims of this study were to analyse and test several types of activated sludge to find out the safe and environmentally friendly fertilizer raw material standards, analyse the characteristics and number of activated sludge components that are potentially safe to use and find out fertilizer raw material standards and also test the response of plants which use the several types of activated sludge in supporting the growth and plant yields that are safe for consumption. The method used is the potential study using a comparative method. The number of raw materials and types of fertilizer raw materials using survey methods and mathematical calculations. The result indicated that the process of wastewater treatment technology that uses waste technology is classified as good and used standards operational with utilization concept. Wastewater in terms of quality and characteristics is considered safe and has a large potential to be used as raw material for fertilizer. Fertilizers sourced from the results of wastewater treatment response to the fresh weight of leaves of Brassica juncea is higher if compared to biofertilizer and chemical fertilizer at the same dosage.
