“…From the test results the total number of bacteria obtained exceeded the set standard, this indicated that the well water in the research area used for daily needs by residents had been contaminated by the presence of coliform bacteria. On average, wells from residents' houses in 4 areas in the Janturan Warungboto area, namely area 16, 17, 18 and 19 are located in the densely populated settlements which may contribute to the quality of water [13]. The previous study found that there are four other factors that influence the level of bacterial content in groundwater, namely the gradient of the groundwater table, the depth of groundwater, the velocity of groundwater flow and the sewage system [14].…”

Water and air are important elements for life. The presence of pathogenic bacteria in the surrounding environment can cause health problems resulting from the low quality of water and air. The purpose of this study is to measure the quality of groundwater and air based on microbiological parameters in urban village housing. This research was conducted in a descriptive survey, and a purposive sampling technique was carried out. Groundwater and air samples were taken from six residents' houses located in the Janturan area. The water quality test used the most probable number (MPN) method and the air quality test used the agar filter method using a microbiological air sampler (MAS) to trap microbes. The results of the MPN test for total coliform bacteria from six samples of groundwater showed that three samples were positive for coliform bacteria which exceeded the threshold according to Indonesian standard<50 MPN/100 ml. Assay of <em>E. coli</em> bacteria showed that all samples of groundwater positively contained <em>E. coli</em> bacteria which exceeded the threshold of 0 MPN/100 ml. The results of indoor air quality measurements from 6 residents' houses showed that five houses have air quality did not meet the standard for indoor air germ numbers based on Indonesian standard, less than 700 CFU/m3 (colony forming units per metres cubic) and 1 house that got the number of airborne germs, in the normal range, namely 356 CFU/m3. It was concluded that the water quality and air quality in the urban village did not meet health requirements.
