Abstract
The use of biomass in Honai indoor (traditional house ) in Wamena has been done for decades and became a habit honai dwellers. Because of the cold temperatures community burns Kasuari wood to warm their body. As a result , they continue to inhale sulfur dioxide (SO2) and contaminated air in the room which can lead to various diseases. This study aims to analyze the level of indoor air contamination honai based on the SO2 parameters, measuring the level of contamination and inhalation lung vital capacity of honai dwellers. Samples were collected from 30 Honai house before and after modification by measuring the concentration of SO2 levels. Similarly, 30 respondents occupants of Honai house measured for their lung vital capacity and the level of their air inhalation. SO2 samples were collected using midget impinger technique and concentration were measured using Pararosaniline - spectrophotometry. In addition, lung vital capacity was measured using spirometry while personal inhalation measured by the Personal inhalation tool. The results showed that, of the five villages average SO2 concentration was between 0.650 ?? 0.454 before modification and 0.057 ?? 0.048 after modification. Statistical test results of t - test showed that the decrease in SO2 concentrations indicated with p values of 0.000, or no effect modification in a decrease in the concentration of SO2 honai. Of the 13 respondents to rate on a standard inhalation, there was 92.3 % which decreased vital capacity of the lungs and of the 17 respondents to the category of sub-standard level of inhalation , all respondents have a capacity of lung function were normal . The results of statistical tests using yate 's correction showed that the value of p = 0.000 which means that there is a relationship between the degree of inhalation with decreased lung function capacity
