Abstract

Activities in building material stores potentially pollute indoor air through construction dust, particularly PM2.5, which poses significant health risks. This study aimed to evaluate indoor air quality regarding PM2.5 concentrations and identify respiratory complaints among workers at Building Material Store X, Gorontalo City. This descriptive observational study involved 15 active workers (total sampling) and measured PM2.5 concentrations at three strategic working points using a Portable Dust Monitor for one hour at five-minute intervals. The results indicated that all sampling points exceeded the threshold value of the Indonesian Ministry of Health Regulation Number 2 of 2023 (25 μg/m3), falling into the category of Not Meeting Requirements. The highest extreme concentration was found in the Cement Warehouse at 1,244.95 μg/m3 (nearly 50 times the threshold value), while the lowest concentration in the showcase area was recorded at 52.77 μg/m3. The health profile of workers revealed a dominance of upper respiratory tract irritation symptoms, with 60% of workers experiencing sneezing, 13.3% coughing, and 6.7% reporting chest tightness. The high particulate exposure, resulting from poor ventilation and lack of personal protective equipment compliance, classifies this work environment as hazardous, necessitating technical ventilation interventions and strict enforcement of occupational health and safety regulations.

Abstract

Air humidity in tropical regions such as Gorontalo City, which is generally high (above 60% RH), can promote the growth of microbial fungi, bacteria, and viruses, as well as increase the risk of respiratory diseases and material damage. This study designs and evaluates the performance of the Advanced Intelligent Relative Humidity System (Airsmart), an automatic microcontroller-based dehumidifier with a DHT22 sensor, to control humidity in real time. The method used is descriptive-analytic; measurements were taken in 36 boarding rooms at two locations (Novalinda Boarding House and Putri Gemilang Boarding House) from March 3–11, 2025. Before using Airsmart, the humidity in each room ranged from 66–83% RH, exceeding the ideal standard set by the Ministry of Health Regulation No. 2 of 2023 (40–60% RH). After operation, humidity decreased significantly to 53–59% RH, with an average reduction of 18% RH (range 10–26% RH), and all rooms (100%) met the ideal standard. These findings confirm the effectiveness of Airsmart in reducing and maintaining air humidity with precision. The application of this device is relevant for private residences, boarding houses, as well as public facilities in humid climate areas, not only enhancing thermal comfort but also reducing the risk of airborne diseases and maintaining indoor air quality. For further development, improving energy efficiency and integrating with Internet of Things (IoT) systems is recommended to expand Airsmart's performance and scope of use.
