PM2.5 in the classroom is a concern because children are a sensitive group to air pollutants. Measurements of PM2.5 and environmental factors in the classroom Elementary School in Bandung City have never been conducted. So the objectives of this study include identifying fluctuations of PM2.5 concentrations in classrooms and semi-outdoor corridors, determining the association between classroom environmental factors and PM2.5 concentrations in classrooms, determining the association between classroom environmental factors and PM2.5 I/O ratio, determining the association between duration class usage and average PM2,5 indoor concentration, determining the effect of classroom environmental factors simultaneously on PM2.5 concentrations in classrooms, identifying whether or not there are differences between PM2.5 concentrations in classrooms from 3 Elementary Schools of Bandung City, and identifying whether or not there are differences in PM2.5 concentrations from classrooms that are close or not close to the road/classroom with 1 or 2 school sessions. The locations of this study were SDN 071 Sukagalih, SDN 001 Merdeka, and SDN 091 Cibereum (different types of road hierarchy and environmental conditions). The main primary data collected included PM2.5, temperature, relative humidity, ratio of ventilation openings area and classroom area, and classroom density. The non-parametric analysis carried out in this study included the Spearman correlation test, Eta correlation test, Robust regression test, Kruskal-Wallis test, and Mann-Whitney test. The results of this study include fluctuations in the form of a significant increase in each elementary school occurring in the morning (07.00-09.00) and evening (19.00-21.00). The association between classroom environmental factors and PM2.5 concentrations in the classroom all showed a weak or very weak association. The association between classroom environmental factors and PM2.5 I/O showed a very weak, weak, to moderate association. There is no association between the duration of class use and the average PM2.5 indoor concentration. These classroom environmental factors simultaneously affect PM2.5 concentrations in the classroom. There are differences in PM2.5 concentrations in classrooms among the 3 primary schools studied. In addition, there were differences in PM2.5 concentrations between classrooms close to and not close to the road. There is no difference in PM2.5 indoor concentration with 1 or 2 school sessions.
