“…In the previous sensor development and evaluation studies, principal component analysis (PCA) has been used to discriminate the sensor sensitivities to various VOCs [31,34,43]. PCA reduces the correlation (redundancy) within the sensor sensitivities for each VOC class and orthogonally projects the sensitivity data on a few uncorrelated dimensions [35] to obtain the maximum variation components that can be used to classify the VOC classes.…”

“…The PPY and PTh based sensors have also been developed for their application in e-nose systems [30][31][32][33] for detection of various VOCs; in several areas such as homeland security, environmental monitoring, and medical diagnosis (breath analysis of diabetic patients and wound monitoring). The CP films of PPY have shown drift in sensor response due to relative humidity during VOC sensing [30,34] whereas PTh derivative, regioregular poly (3-hexyl thiophene) (rr-P3HT) has shown less affinity towards water during VOC sensing [31]. Moreover, the rr-P3HT forms highly ordered crystalline structure films during sensor development that are needed to sense analyte VOCs at trace level concentration with increased sensitivity [33,35].…”

This study was aimed at the development and evaluation of regioregular poly (3-hexyl thiophene) (rr-P3HT) based chemoresistive sensors to detect the alcoholic volatile organic compounds (VOCs): 3-methyl-1-butanol and 1-hexanol, found to be present in spoiled and Salmonella typhimurium contaminated beef packages. The sensors were developed using two types of dip coating methods: (1) vertical dip (90°), and (2) inclined dip (10°). Five layers of rr-P3HT were deposited on tin interdigitated flame retardant FR4 substrates. The morphological studies revealed that the rr-P3HT sensors developed with the inclined dip coating method had formed relatively smooth thin-film of rr-P3HT than sensors developed using the vertical dip coating method. The sensitivities of the vertical dip and inclined dip coated sensors were found to be repeatable for the same concentration and were also reproducible among different sensors for same VOC. The sensors exhibited selective response to trace level concentrations of 3-methyl-1-butanol and 1-hexanol, with a lower detection limit of about 10 and 15 ppm, respectively.

“…Afterward, the air will flow into the humidifier to maintain humidity around 95-100%. The bacteria in the biofilm attached to the filter media will degrade the odor, and the biodegradation could deodorize most odor substances [21]. The work scheme of the biofilter model is shown in Fig.…”

“…7. During the biofiltration process, microorganisms would consume odor substances, and the products of biodegradation were CO2, water steam, and heat [21]. The effectiveness of odor reduction (NH3 and H2S) depends on the used filter media material and the mixture between the filter media and compost [22].…”

The odor affects both one’s health and quality of life. This study measures and analyzes odor concentration and odor sources in ambient air, the correlation between odor gas concentration and the hedonic scale, and the design of an odor-reduction instrument. The research commenced from February to May 2022 in the small industrial area (SIA) of Magetan Regency and compost bins of Bogor City. Data was collected through chemical analysis, and the hedonic scale was measured at four points divided into radii one and two. The concentration of odor parameters in Magetan and Bogor City is below the quality standard, while the correlation between ammonia gas concentration and the hedonic scale is low. Regarding the biofilter, its odor reduction efficiency is 35% for rotten fish, 70% for goat manure, 82% for compost waste, and 47% for chicken carcasses.

The aim of this research was to study whether electronic nose sensor technology (NST 3320, Applied Sensor, Sweden) can be used effectively for monitoring of the composting process. The effect of aeration on the composting process was examined using two aeration levels representing insufficient and optimal aeration for composting. An additional aim was to identify possible indicator gases in the volatile organic compound profiles of the composts by on-line FT-IR and gas chromatographic determinations. The results indicated that the electronic nose was able to distinguish between the two composter bins after 13 days of composting. Of the volatile metabolites that were identified, methyl ethyl ketone (MEK) proved to be a suitable indicator compound of anaerobicity as it was only produced in considerable quantities in the insufficiently aerated composter bin.
