Laundry waste contains detergent and phosphate which cause environmental pollution, eutrophication and serious health problems in humans. One of the alternative technologies for laundry waste treatment that is environmentally friendly is Effective Microorganisms (EM). Utilization of vegetable waste as EM is carried out because decomposing vegetables have many microorganisms contained. Microorganisms in vegetables are thought to reduce organic waste. This research aimed to assess the efficiency of reducing COD and phosphate levels in laundry wastewater using EM vegetable waste. The number of reactors consisted of 4 reactors where the EM dosage was 0%, 5%, 10% and 15%, respectively. The results showed that the highest efficiency levels of COD with a dose of 0%, 5%, 10% and 15% were 10.2%, 43.9%, 51% and 59.9%. Whereas for the phosphate level the highest reduction efficiency was at a dose of 0%, 5%, 10% and 15% respectively, namely 0.7%, 53.2%, 56.5% and 65.2%. The effective dose to reduce COD and phosphate in laundry waste is 15%.

The potential for agricultural waste such as rice husks and corn cobs is very abundant and also can disturb the environment. However, this waste can be returned to agricultural land in the form of biochar or activated charcoal by means of pyrolysis using either low temperature or high temperature. Biochar is a byproduct of the thermochemical conversion of biomass which is recognized as a favorable soil amendment, which is introduced into the soil to increases groundwater retention in order to increases the saturated hydraulic conductivity of upper soil, affecting an aggregation, infiltration, and water capacity, decreasesing soil penetration resistance. Based on several previous studies, biochar can bind heavy metals contained in leachate, especially heavy metal Fe content. Utilization of leachate as an organic fertilizer which contains many nutrients essential for the growth of soybean plants. This research purposes to get the Fe-reduction influenced by biochar based on rice husk. The method used is to make biochar by pyrolysis process with low to high temperatures to obtain adsorption of heavy metals contained by leachate.

Surabaya River is a second class (class II) river that flows from DAM Lengkong Mojokerto to DAM Jagir Surabaya. Surabaya River potentially polluted from industries around it, because 29% land around Surabaya River used for industrial area. The purpose of this study was to find out the BOD and DO distribution pattern using Geographic Information System (GIS) method and its relationship with self-purification process in Surabaya River. From the research, it found that the BOD value in Surabaya River is over the class II water quality standadts. Based on regression statistical analysis, it found that the most affect of the BOD value in Surabaya River was DO. The higher flow discharge, DO, and pH values the lower BOD value. But if the temperature value increases, the BOD value also increases too. Surabaya River has characteristics deoxygenation constant value (K1) is 0.12 – 0.20 /day and the reaeration constant value (K2) is 0.29 – 0.54 /day. This constant value (K1 and K2) greatly affect the Streeter-Phelps self-purification equation. With the distance of 0.3 Km from point 1 to point 2 DO has increased by 0.52 mg/lt. Whereas at point 9 to point 12 with the distance of 1.2 Km there is an increase in DO of 0.80 mg/lt. At longer distance, the ability of self-purification will be better if there will be no longer input into the river.
