Identifikasi Bahaya Tanah Longsor Menggunakan Metode Very Low Frequency (VLF) Di Bedeng Rejo, Merangin, Jambi
نویسندگان
چکیده
Desa Bedeng Rejo dikenal sebagai salah satu daerah yang berpotensi dalam terjadinya tanah longsor. Metode Very Low Frequency (VLF) digunakan untuk identifikasi bahaya longsor berdasarkan parameter konduktivitas batuan didukung kemiringan lereng (slope). Penelitian ini dilakukan menggunakan T-VLF dengan panjang lintasan 200 meter, jarak antar titik ukur 10 meter dan frekuensi pengukuran sebesar 22200 Hz (Jepang). Jenis VLF yaitu mode tilt-angle. Ditemukan anomali konduktif berada pada rentang 100 - 120 di bawah permukaan bumi 40 170 190 kedalaman 30 meter. Perhitungan VLF, didapatkan – 25% 12,5 16,67% merupakan lahan curam, rentan terhadap longsor, mudah tererosi.

Biological Effects of Very Low Frequency (VLF) Atmospherics in Humans: A Review
Ð The living organism is constantly affected by natural electromagnetic influences covering a wide range of frequencies and amplitudes. One of these influences, with frequencies in the very low frequency (VLF) range, (1-100 kHz) is represented by a phenomenon called VLF-atmospherics or VLF-sferics. Sferics are very short, weak, and dampened electromagnetic impulses generated by atmospheric disc...

two dimensional single frequency scalar vlf data modeling has been studied in this research. vlf method is one of the electromagnetic investigation methods. radio frequency waves are used for investigation of conductive deposits (paal, 1968). synthetic modeling and inversion of single frequency and multiple frequencies of vlf signals was done by oskooi (2004) for two dimensional simple structur...
متن کاملFrequency of Thyroid Function Disorders among a Population of Very-Low-Birth-Weight Premature Infants
Background: Thyroid function disorders, particularly congenital hypothyroidism (CHT), are important endocrine dysfunctions associated with permanent morbidities. CHT is more prevalent among preterm low-birth-weight neonates compared to term infants with normal weight. Methods: This prospective cohort study was conducted on 126 very-low-birth-weight (VLBW) neonates referred to the neonatal inten...
