Abstract
Terjadinya pencemaran udara berdampak pada kualitas lingkungan sekitar. Pencemaran udara dapat terjadi pada udara luar dan dalam ruangan. Pencemaran udara dapat disebabkan oleh sumber pencemar yang bersifat fisik, kimiawi, dan biologis. Kualitas udara dalam ruangan dapat terpengaruh apabila jumlah sumber pencemar biologis melewati
standar baku mutu. Salah satu ruangan yang perlu diteliti kualitas mikrobiologis udaranya yaitu lantai 1 gedung perpustakaan ITS Sukolilo Surabaya. Tujuan penelitian ini yaitu menentukan kualitas mikrobiologis udara ruangan, mengidentifikasi faktor yang memengaruhi perkembangan bakteri dan fungi dalam ruangan, dan menentukan hubungan antara kualitas mikrobiologis udara ruangan dengan kejadian Sick Building Syndrome.
Dalam penelitian ini, terdapat dua metode yang digunakan, berupa metode pasif, yaitu settle plate dan metode aktif, yaitu impingement sampling. Lokasi pengambilan sampel ditentukan di lantai satu gedung perpustakaan. Hal yang perlu diperhatikan dalam menentukan titik sampel yaitu suhu, kelembapan, dan intensitas cahaya. Masing-masing parameter diukur secara langsung dilokasi yang bersamaan dengan pengukuran jumlah koloni bakteri dan fungi.
Berdasarkan penelitian yang dilakukan, diketahui jumlah koloni bakteri dan fungi dalam udara enam ruangan pada lantai satu gedung perpustakaan memiliki rata-rata sebesar 58 CFU/m3 untuk bakteri dan 38 CFU/m3 untuk fungi, sehingga disimpulkan kualitas mikrobiologis udara indoor lantai satu gedung perpustakaan ITS masih memenuhi standar baku mutu
Peraturan Menteri Tenaga Kerja No. 5 Tahun 2018. Faktor yang memengaruhi kualitas mikrobiologis udara yaitu suhu, memiliki korelasi yang kuat terhadap jumlah koloni dengan
nilai koefisien Pearson -0,642, dengan tanda negatif bermakna hubungan berlawanan. Adanya pengaruh yang kuat antara suhu dengan jumlah koloni, sebesar 41,3%. Pada kelembapan, memiliki korelasi yang sangat kuat terhadap jumlah koloni dengan nilai koefisien Pearson 0,953, dengan tanda positif bermakna hubungan searah. Adanya pengaruh yang sangat kuat antara kelembapan dengan jumlah koloni, sebesar 87,5%. Sedangkan intensitas cahaya memiliki korelasi yang rendah terhadap jumlah koloni dengan nilai koefisien Pearson 0,256, dengan nilai positif bermakna hubungan searah. Adanya pengaruh yang lemah antara intensitas cahaya dengan jumlah koloni, sebesar 6,5%. Korelasi kejadian Sick Building
Syndrome dengan kualitas mikrobiologis udara tergolong rendah dengan nilai koefisien korelasi Pearson 0,379, dengan nilai positif bermakna hubungan searah. Adanya pengaruh
yang lemah antara gejala SBS dengan jumlah koloni, sebesar 14,4%.

The occurrence of air pollution has an impact on the quality of the surrounding environment. Air pollution can occur in outdoor and indoor. Air pollution can be caused by physical, chemical and biological pollutants. Indoor air quality can be affected if the number of biological pollutant sources exceeds the quality standard. One room that needs to be studied on the microbiological quality of the air is the 1st floor of the ITS Sukolilo Surabaya library building. The purpose of this study is to determine the microbiological quality of indoor air, factors that affect the development of bacteria and fungi in the room, and determine the
relationship between the microbiological quality of indoor air and the incidence of Sick Building Syndrome.
In this study, there are two methods used, in the form of passive methods, namely settle plate and active methods, namely impingement sampling. The sampling location was
determined on the first floor of the library building. Things that need to be considered in determining sample points such as temperature, humidity, and light intensity. Each parameter was measured directly at the location simultaneously with the measurement of the number of
bacterial and fungal colonies.
Based on the research, it was found that the average colony count of bacteria and fungi in the air from six rooms on the first floor is 58 CFU/m3 for bacteria and 38 CFU/m3
for fungi, concluding that the quality of microbiological of indoor air on the first floor of the ITS library building still meets the standards of the Government Standard of Minister of Manpower Regulation No. 5 of 2018. The factors affecting indoor air microbiological quality include
temperature, which has a strong correlation with the number of colonies, with a Pearson correlation coefficient of -0,642, indicating an inverse relationship. There is a strong influence between temperature and the number of colonies, amounting to 41,3%. Humidity has a very strong correlation with the number of colonies, with a Pearson correlation coefficient of 0,953, indicating a direct relationship. There is a very strong influence between humidity and the number of colonies, amounting to 87.5%. Meanwhile, light intensity has a low correlation with
the number of colonies, with a Pearson correlation coefficient of 0,256, indicating a direct relationship. There is a weak influence between light intensity and the number of colonies, amounting to 6.5%. The correlation between the occurrence of Sick Building Syndrome and
microbiological air quality is low, with a Pearson correlation coefficient of 0,379, indicating a direct relationship. There is a weak influence between SBS symptoms and the number of colonies, amounting to 14.4%.
