Popis: Domestic wastewater contributes about 40% as the source of water bodies pollutants in Indonesia, causing the spread of pathogens and bioaccumulation effects on the environment. The purpose of this study was to analyze the characteristics of household wastewater in Jakarta and Depok in terms of quantity and quality. The average wastewater quantity estimation results from laundry, bathroom, kitchen, and closet were 49 ± 18, 79.1 ± 5, 24.5 ± 12, and 29.9 ± 3 liters/person/day. The qualitative analysis results stated that blackwater tends to have higher concentration on conductivity 1606-2046 μs/cm, TDS 709-1007 mg/L, ammonia 78-167 mg/L, total nitrogen 511-836 mg/L, total phosphorus 16.6-21.3 mg/L, phosphate 33-46.8 mg/L, potassium 32.5-47.9 mg/L, and fecal coliform 430,000-1.600,000 MPN/100 mL compared to other sources. Meanwhile, laundry greywater tends to have higher concentration on COD 559-1991.6 mg/L, MBAS 0.3-0.31 mg/L, aluminum 1.65-5.09 mg/L, sodium 7.5-61.4 mg/L, and silica 17.7-23.2 mg/L compared to other sources. Statistical results show that some parameters have significant difference in average concentration between each source so that these parameters can be considered as source tracer. The high pollutant concentration and quantity leads to high estimation of pollutant load on the river, as water bodies receiver, in Jakarta and Depok, especially on organic and nutrient load.
