Analisis Intensitas Medan Listrik pada Pemukiman akibat Sambaran Petir pada Menara Base Transceiver Station Analysis of Electric Field Intensity in Residential Areas Due to Lightning Strikes on Base Transceiver Station Towers
No full textBase Transceiver Station (BTS) towers are highly vulnerable to lightning strikes. A lightning strike is a moving electric charge that generates an electric field and a magnetic field, both of which are vector quantities, and induces voltage around the tower. The closer to the tower, the greater the values of the electric field, magnetic field, and induced voltage generated. A 49-meter highs tower in Mataram City is located 25 and 300 meters from residential areas and public facilities. The metabolism of living organisms, such as blood circulation, nerve function, heart rate, lung function, cell growth, and cell division, are also vector quantities. Exposure of living organisms to external electric fields exceeding the threshold of ≥10 kV/m can disrupt their metabolism. It is crucial to determine the magnitude and direction of the electric field vector caused by lightning strikes on BTS towers and how it affects living organisms around the tower. Observations are based on Coulomb's Law and its derivative theories on electric fields. The peak lightning current in tropical areas ranges from 10 to 100 kA, with a frequency of 200 kHz. The electric field intensity at distances of 25 and 300 meters is 58.30, 584.50, 4.86, and 48.71 kV/m, respectively. These results indicate that a distance of 25 meters from the tower is not safe from exposure to high electric field intensity values.Menara Base Transceiver Station (BTS) sangat rentan di sambar petir. Sambaran petir adalah muatan listrik yang bergerak yang membangkitkan medan listrik dan medan magnet yang merupakan besaran vektor, serta membangkitkan tegangan induksi di sekitar menara. Semakin dekat dengan menara, nilai medan listrik, medan magnet dan tegangan induksi yang dibangkitkan semakin besar. Sebuah menara tinggi 49 meter di Kota Mataram berjarak 25 dan 300 m dari pemukiman penduduk dan fasilitas umum. Metabolisme makhluk hidup seperti peredaran darah, kerja syaraf, detak jantung, kerja paru-paru, pertumbuhan sel, pembelahan sel juga merupakan besaran vektor. Terpaparnya makhluk hidup dari medan listrik eksternal yang melebihi ambang batas yaitu 10 kV/m dapat mengganggu metabolisme mahluk hidup. Besaran dan arah vektor medan listrik akibat sambaran petir pada menara BTS yang diterima oleh mahluk hidup di sekitar menara sangat penting diketahui nilainya. Observasi menggunakan Hukum Gaya Coulomb beserta teori turunannya tentang medan listrik. Arus puncak petir di daerah tropis tertinggi dan terendah yaitu 10 dan 100 kA, frekuensi 200 kHz, intensitas medan listrik pada jarak 25 dan 300 meter masing-masing adalah 58,3; 584,5; 4,86 dan 48,716 kV/m. Hasil ini menunjukan jarak 25 m dari menara belum aman dari paparan nilai intensitas medan listrik.
