Paparan partikel halus (PM2.5) di dalam ruangan dapat berdampak buruk bagi kesehatan, sehingga diperlukan solusi yang efektif dan terjangkau. Penelitian ini bertujuan menguji efektivitas penggunaan air purifier sederhana dengan filter HEPA berbahan meltblown nonwoven polypropylene dalam menurunkan konsentrasi PM2.5 di ruang tertutup. Eksperimen dilakukan di Laboratorium K3 FKM UI pada Januari–April 2025, dengan dua skenario utama: satu dan dua unit air purifier. Pengukuran dilakukan secara real-time menggunakan air particle counter CEM DT-9883M, serta didukung data suhu, kelembaban, kecepatan aliran udara, dan putaran kipas. Hasil menunjukkan bahwa dua air purifier lebih efektif dibanding satu unit, terutama jika ditempatkan di posisi depan dan belakang ruangan, dengan rata-rata penurunan konsentrasi PM2.5 mencapai 98,8%. Efektivitas konfigurasi ini sekitar 5% lebih tinggi dibandingkan penggunaan satu alat. Selain itu, penggantian turbin pada air purifier tunggal juga memberikan hasil lebih baik, menurunkan konsentrasi dari 56,67 µg/m³ menjadi 46 µg/m³. Hasil ini menegaskan bahwa peningkatan jumlah dan penataan posisi air purifier dapat menjadi strategi sederhana namun signifikan dalam memperbaiki kualitas udara dalam ruangan.

Indoor fine particle exposure (PM2.5) can have a negative impact on health, so an effective and affordable solution is needed. This study aims to prove the effectiveness of using a simple air purifier with a HEPA filter made of Meltblown Nonwoven Polypropylene in reducing PM2.5 concentrations in closed spaces. The experiment was conducted at the FKM UI K3 Laboratory in January–April 2025, with two main scenarios: one and two air purifier units. Measurements were carried out in real time using a CEM DT-9883M air particle counter, and supported by data on temperature, humidity, air flow speed, and fan rotation. The results showed that two air purifiers were more effective than one unit, especially when placed at the front and back of the room, with an average reduction in PM2.5 concentration reaching 98.8%. The effectiveness of this configuration is about 5% higher than using one device. In addition, the placement of the turbine on a single air purifier also gave better results, reducing the concentration from 56.67 µg/m³ to 46 µg/m³. These results confirm that increasing the number and positioning of air purifiers can be a simple yet significant strategy in improving indoor air quality.

Sick Building Syndrome (SBS) merupakan masalah kesehatan di tempat kerja yang berkaitan dengan Kualitas Udara dalam Ruangan (KUDR), dan dapat memengaruhi hingga 90% pekerja secara global. Penelitian ini bertujuan untuk mengetahui hubungan antara KUDR dan gejala SBS pada pustakawan di lima perpustakaan Universitas X Depok. Desain penelitian yang digunakan adalah cross-sectional, dengan 47 responden terpilih secara purposive dan analisis dilakukan hingga tingkat bivariat. Sebanyak 57,4% responden melaporkan gejala SBS. Suhu udara berhubungan signifikan dengan SBS (OR=5,00; 95% CI=1,32–18,96), dan hubungan ini tetap bertahan setelah dikontrol berdasarkan lama bekerja. Temuan ini menunjukkan perlunya perbaikan kondisi termal di lingkungan perpustakaan, termasuk pemeliharaan dan perbaikan sistem pendingin udara, guna menurunkan risiko SBS pada pustakawan.

Sick Building Syndrome (SBS) is a workplace health issue linked to Indoor Air Quality (IAQ), affecting up to 90% of workers globally. This study investigates the relationship between IAQ and SBS symptoms among librarians in five libraries at University X, Depok. Using a cross-sectional design, data were collected from 47 purposively selected respondents and analyzed to bivariate level. SBS symptoms were reported by 57.4% of participants. Air temperature was significantly associated with SBS (OR=5.00; 95% CI=1.32–18.96), and the association persisted after adjusting for length of employment. These findings highlight the need to improve thermal conditions in library environments, including air conditioning maintenance and repairs, to reduce SBS risk among librarians.

Kualitas udara dalam ruangan kelja yang tidak memenuhi persyaratan kesehatan dapat menyebabkan ruangan kerja tidak nyaman; dampak negatif terhadap karyawan berupa keluhan kesehatan yang dikenal dengan istilah sick building syndrome 6985). Keluhan SBS biasanya tidak terlalu parah dan tidak diketahui penyebabnya, tetapi mengurangi produktivitas kerja. Sejumlah penelitian pada lingkungan yang berbeda menunjukkan bahwa faktor-faktor intcmal dan ekstemal mempengaruhi kejadian SBS. Informasi mengenai kualitas udara dalam mangan gedung perkantoran Departemen Kesehatan (Dcpkes) belum dikctahui, walaupun sudah banyak Iaporan tentang keluhan SBS. Tujuan penelitian untuk memperoleh informasi mengenai kualitas udara di gcdung Depkes Jakarta, Serta kejadian SBS dan ihktor-faktor yang mempengaruhinya. Menggunakan studi cross-seczional hersifat deskriptif analitik; melibatkan 242 karyawan Depkes scbagai responden.

Indoor air quality that does not meet the health standard requirement may lead to uncomfortable working environment and causes negative impacts to the workers in the fomm of health complaints known as sick building .syndrome (SBS). Usually the complaints are not very serious and the sources are unknown; however it could reduce work productivity. A number of studies in different settings have indicated that several internal and external factors influence the incidence of SBS. Infomation on the indoor air quality of the Ministry of Health (MOH) building has not yet been known, in spite ofthe SBS complaints that have been reported. The purpose of this study is to obtain infomation on the indoor air quality ofthe MOH building Jakarta, as well as the incidence of SBS and its’ underlying thctors. Using cross-sectional study which is descriptive-analytic; the study involved 242 MOH employees as respondents. The criteria ofthe respondents were healthy individuals not suffering from diseases as diagnosed by a physician and not pregnant. To obtain data on the characteristics, psychological and ergonomic working position of the respondents, guided and structured questionnaire were used. Whereas measurements of NO;, CO, CO2, S02, I-I2S, NH, and PM10 concentrations as indicators of air quality were undertaken in ten rooms. Indoor air quality still meets the standard requirement, in accordance to the Minister of Health Decree No. 1405/ivlenkes/SK/XI/2002. Concentrations of NO2, SO2, and Nl-I; were detected in three rooms. The concentration of CO in all rooms was the same; while CO2, l-l2S, and PM10 were detected in all rooms with different concentrations. Illuminations in all rooms were in compliance to the standard requirement (> 100 lux). On the other hand, the temperature and humidity in some rooms exceeded the standard requirement, however, in general the average value of these two variables still meet the requirements. The prevalence of SBS was 19%, mostly in the fonn of fatigue, pain and stiff on the shoulder and neck (50%); common cold, coughing and sneezing (49.6%); as well as diuiness, headache and concentration problems (38.4%). Temperature, ergonomic working position, sex and age significantly influence the incidence of SBS, in which the room temperature was shown to be the predominant variable. Indoor air quality was still in compliance to the health standard requirement. As for the physical environment, the measurement average values still meet the requirements although the temperature and humidity in some rooms did not. _ Temperature, ergonomic working position, sex and age significantly influence the incidence of SBS. Maintenance of the air conditioner and sustaining ergonomic working position are prevention actions that should acquire attention in the SBS program.
