Abstract
Introduction: The Community Health Center is a gathering place for healthy people and sick people, so that it has the potential to become a place for disease transmission. Transmission of the disease can be influenced by the presence of germs in the air. The results of a preliminary study measuring germ numbers showed concentrations of 2575 CFU / m3, 945 CFU / m3 and 492 CFU / m3 exceeding the threshold according to the American Conference of Governmental Industrial Hygienists (ACGHI). The magnitude of potential health risks, especially puskesmas, can threaten the health of officers, patients and the community. The purpose of this study was to determine the magnitude of the risk of exposure to airborne germs on the health of health center staff. Method: This research is an analytical study using Microbial Risk Assessment (MRA) method. The sample in this study is the general BP room and KIA-KB room in 13 health centers with a sample of 96 respondents at risk. Concentration of airborne germ numbers was measured using a MAS eco 100 (Microbial Air Sampler) tool. Sampling was carried out with an air volume of 200 liters / minute for 5 minutes according to MAS standards in March - May 2020. Samples were examined at the Semarang City Health Laboratory. Results: The results showed 44 sample points (42.72%) exceeded the standard threshold required by ACGHI which is 500 CFU / m3. Concentration of airborne germ numbers exceeds the threshold at the Bugangan Public Health Center, Ngemplak Simongan, Karangmalang, Miroto, Purwoyoso and the Gunungpati community health center,. Concentration of the number of germs that enter the body of the respondents ranged from 4.69 CFU / kg / day to 23.82 CFU / kg / day. From the MRA calculation the risk characteristics (HQ) values obtained in 13 HQ health centers> 1 with a 9x10-1 probbability of infection or 9 cases of infection per 10 people. Conclusion: The results obtained by the level of risk of airborne germ count HQ> 1, it shows that the risk agent is said to be unsafe and risk to the health of officers
