Analysis of domestic waste generation in one of residential areas on Srondol Wetan Sub-districts, Banyumanik District, Semarang City

Abstract The more densely populated an area is, the greater the waste produced. One of the residential areas in the Banyumanik District, Semarang City with a relatively high population density is in RW 07 Srondol Wetan Sub-district. Therefore, a study was conducted to determine the amount of waste generated, the volume, and the composition in RW 07 Srondol Wetan Sub-district by implementing waste sampling that refers to SNI 19-3964-1994. Other data collection was carried out by observing and conducting surveys. The samples range from low, middle, to high-income housing. Based on the result, the weight of waste generation in RW 07 Srondol Wetan Sub-district is 0.2836 kg/person/day, and the volume of waste generation is 2.9333 liter/person/day. The composition of the waste generated consists of 61.90% food waste, 11.63% plastic, 6.41% paper or cardboard, 12.26% leaves and wood, 0.93% fabric, 0.37% metal, 0.42% glass, 0.02% rubber, and 6.06% other waste. Based on observations and interviews, most of the waste is collected and transported by collectors and then disposed of directly to the nearest TPS. Meanwhile, waste sorting is only carried out on organic waste and only a few residents process waste using the composting method. Some residents have already done waste management in the form of collecting and selling valuable waste, which is a good indication of the need for a waste bank in the area.
