Abstract
SUTT tegangannya disalurkan sebesar 70 kV hingga 150 kV. distribusi dan saluran transmisi listrik merupakan sumber terbesar dan medan elektromagnetik terhadap lingkungan (Moon dan Chung 2000; Martinez et al, 2002 dalam Mahmood et al., 2013). Tanah terkontaminasi medan listrik karena berada di dekat distribusi dan saluran tegangan tinggi (Roy dan Lee, 1984 dalam Wessam dan Akram; 2004). Menurut Wessam dan Akram (2004) Medan listrik dapat mempengaruhi migrasi ion, gerakan ion dan juga mikroorganisme pada tanah. Penelitian ini bertujuan mengetahui pengaruh medan listrik SUTT terhadap unsur K tersedia, pH, dan KTK pada tanah. Hipotesis penelitian ini ialah medan listrik SUTT meningkatkan unsur K tersedia, pH, dan KTK pada tanah. Penelitian ini berguna untuk memberikan informasi kepada petani bagaimana pengaruh saluran udara tegangan tinggi yang berada di sekitar lahan pertanian terhadap unsur K tersedia, pH, dan KTK pada tanah. Penelitian ini dilakukan pada Agustus 2015 – januari 2016 di tempat kegiatan bercocok tanamnya berada di sekitar saluran udara tegangan tinggi Desa Jenggolo, Kecamatan Kepanjen, Malang. 1) Survei lapang, 2) Perizinan ada 2 kegiatan yaitu perizinan kepada PT PLN APP Malang untuk membantu pengukuran medan listrik pada saluran udara tegangan tinggi dan meminta izin kepada petani bahwa akan melaksanakan pengukuran medan listrik serta pengambilan sampel tanah, 3) Pengukuran medan listrik pada saluran udara tegangan tinggi, dan 4) Pengambilan sampel tanah (komposit) dan Pengukuran dan pengambilan sampel menggunakan empat plot (n = 4) sisi kiri dan sisi kanan menara dilakukan enam ulangan (n = 6) dengan perbedaan jarak 8 meter pada tiap plot. Variabel pengamatan meliputi K (me/100g), pH H2O, KTK (me/100g) dan tekstur tanah, sedangkan SUTT mengukur medan listrik. Medan listrik diperoleh plot A) 0,350 kV/m, B) 0,254 kV/m, C) 0,171 kV/m, D) 0,099 kV/m. Kesimpulan penelitian ini Medan listrik SUTT tidak mempengaruhi unsur K tersedia, pH, dan KTK pada tanah.
English Abstract
The high voltage transmission line is supplied 70 – 150 kV. Distribution and electricity transmission line is the largest source of electromagnetic fields on the environment (Moon and Chung, 2000; Martinez et al., 2002 in Mahmood et al., 2013. Soil contaminated because of the electric field is near the distribution and high voltage lines (Roy and Lee, 1984 in Wessam and Akram, 2004). According to Wessam and Akram (2004) the electric field able to influence the migration of ions, ion movements and also microorganisms in the soil. This sudy aims to determine the influence of electric field the high voltage transmission line to potassium (K) availability, pH, and CEC on the soil. The hypothesis of this research is whether an electric field the high voltage transmission line increase potassium (K) availability, pH, and CEC on the soil. This research is useful to provide information to farmers how the high voltage transmission line that are around the farms influence potassium (K) availability, pH, and CEC on the soil. This research was done in August 2015 – January 2016 in the farming activities cropping be around the high voltage transmission line Jenggolo Village, District Kepanjen, Malang. 1) Field survey, 2) The permissions is there are two activities that permit to PT. PLN APP Malang to help measurement of the electric field on The High Voltage Transmission Line and asked for permission to farmers that would carry out measurements of electric field and soil sampling, 3) Measurements of electric field on The High Voltage Transmission Line, and 4) Soil sampling and measurement using four plots the left side and the right side of the tower was carried out six replicates (n = 6) with difference within 8 meters on each plot. The variables observation include of K (me/100g), pH H2O, CEC (me/100g) and soil texture, while The High Voltage Transmission Line measure the electric field (kV/m). The electric field is obtained plot A) 0,350 kV/m, B) 0,254 kV/m, C) 0,171 kV/m, D) 0,099 kV/m. . It is concluded that the electric field The High Voltage Transmission Line does not affect potassium (K) Availability, pH, and CEC on the soil.
