Humidifier modification with sanseviera sp. extract solution to decrease indoor mold growth

This research was motivated by microbial air contamination such as mold, fungi, viruses, and bacteria. Indoor microbiological air contamination is more dangerous rather than outdoor microbial contamination. The purpose in this research was to understand the decreasing of Indoor Mold Number using Humidifier Modification with Sanseviera sp. Extract Solution. To understand this thing, we would count indoor mold number before and after using sanseviera extract as additional material in humidifier, next we would analyze the effectiveness of this method. Pra experiment was done by using One Group Pre-Post Test Design. Independent variable in this research was Sanseveira extract concentration (50%, 70%, and 100%) and dependent variable was mold number. Data was tested using paired t test and anova test. The average results in 0% concentration was 30,59 CFU/m3, 50% concentration was 24,62 CFU/m3 and 70% concentration was 28,62 CFU/m3. The results showed that there was a significant difference between the mold number before and after sanseviera added. But the results of mold number in both concentrations still can not fulfill the Indonesian regulation Permenkes 1077/ Menkes/Per/V/2011, that was 0 CFU/m3. Only 100% of sanseviera extract that fulfill this regulation. The percentages of mold number decreasing in 50% concentration was 23,74%, in 70% concentration was 42,79% and in 100% it decreased until 100%. It also makes 100% concentration was the most effective to decrease indoor mold number. The conclusion from this research was Sanseviera Solution Extract can be used as additional material in Humidifier Modification to decrease indoor mold number. We recommend for the development of science and technology that are appropriate for environmental health related to the control air pollution tested to modify the Sanseviera extract solution or other extract which can also absorb pollutants.
