Puspitasari, Elma Dwi (2019) Pengaruh Paparan Gelombang Elektromagnetik Frekuensi Radio Gsm 900 Mhz Terhadap Produksi Sel Cd4 Dalam Sel Darah Kultur Pheripheral Blood Mononuclear Cells (PBMC). Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk menganalisis jumlah produksi CD4 akibat paparan gelombang elektomagnetik frekuensi radio GSM 900 MHz untuk mengetahui pengaruhnya terhadap sistem imun dalam tubuh. Sampel darah yang digunakan berasal dari 12 donor yang kemudian dikultur Pheripheral Blood Mononuclear Cells (PBMC). Proses pemaparan RF 900 MHz dilakukan dengan pemancar VSG25A. Perlakuan yang diberikan adalah variasi jarak antenna dengan wadah sampel yaitu 0 cm, 2.5 cm, dan 5 cm serta variasi waktu paparan 15, 30, 45, dan 60 menit. Dari penelitian yang telah dilakukan dapat ditarik kesimpulan bahwa terjadi peningkatan jumlah CD4 akibat dipapari gelombang elektromagnetik frekuensi radio GSM 900 MHz. Peningkatan tersebut ditunjukkan dengan bertambahnya persentase perubahan jumlah CD4 dalam PBMC sebanding dengan waktu pemberian paparan radiasi untuk setiap jarak dengan tingkat korelasi ±0,75. Nilai perubahan jumlah CD4 tertinggi terjadi pada perlakuan dengan jarak 2,5 cm dan durasi paparan 60 menit.
English Abstract
This study aims to analyze the number of CD4 production due to electomagnetic waves exposure of GSM 900 MHz radio frequency to determine the effect on the immune system in the body. The blood samples used came from 12 donors which were cultured Pheripheral Blood Mononuclear Cells (PBMC). The 900 MHz RF exposure process used a VSG25A transmitter. The treatment given is the variation of antenna distance with sample containers, that are 0 cm, 2.5 cm, and 5 cm and variations in exposure times of 15, 30, 45, and 60 minutes. From the research that has been done can be concluded that there is an increase in CD4 number due to exposure to GSM 900 MHz radio frequency electromagnetic waves. That was indicated by the increase in the changing percentage of CD4 number in PBMC proportional to the radiation exposure duration for each distance with a correlation level of ±0.75. The highest change in CD4 number based on trendline occurred when the treatment with a distance of 2.5 cm and 60 minutes of exposure was applied.
