Carbon monoxide is the largest contributor to air pollution sourced from motor vehicle gas discharge. High levels of carbon monoxide in the air can affect human health. This study aims to determine the level of carboxyemoglobin in active smoker students at Sekolah Tinggi Ilmu Kesehatan Nasional National with conway diffusion cell method. This research is descriptive research with sampling techniques, namely quota sampling and analysis used that is simple linear regression. The study subjects were 7 respondents drawn from the population according to the specified criteria. COHb level examination using UV-Vis A&E Lab Spectrophotometer. The results of the study obtained COHb levels between 0.3770% - 0.4839% of 7 respondents namely KODE 2 = 0.4344%; CODE 5 = 0.3960%; CODE 8 = 0.3770%; CODE 12 = 0.4268%; CODE 13 = 0.4114%; CODE 14 = 0.4238%; and CODE 15 = 0.4839%. Linear regression line obtained by Y=0.9388x ? 0.0107 at wavelengths of 371 nm with an Operating Time of 60-120 minutes. The conclusion in this study is that the level of carboxsihemoglobin in the blood of active smokers in Sekolah Tinggi Ilmu Kesehatan Nasional Nasional is still within the safe threshold according to PERMENKES RI Number 70 of 2016 which is no more than 3.5%.} }
