Alak Lindi Resistivitas Schlumberger TPA

Abstract

Metode geolistrik resistivitas Schlumberger telah diterapkan untuk memperkirakan kedalaman rembesan lindi TPA Alak Kota Kupang. Survei geolistrik menggunakan resistivity meter tipe Naninura NRD-300 HF dengan jarak elektroda potensial antara 0,5 meter - 10 meter. Pengambilan data dilakukan pada empat lintasan yang mewakili lokasi TPA. Lintasan 1 di utara barat laut dengan panjang lintasan 300 meter, lintasan 2 di barat laut sepanjang 275 meter, lintasan 3 di timur tenggara dengan panjang lintasan 300 meter, dan lintasan 4 di barat daya sepanjang 300 meter. Data geolistrik diolah dengan model inversi untuk memperkirakan kedalaman rembesan lindi. Hasil penelitian menunjukkan bahwa nilai resistivitas berkisar antara 0,242 Ωm sampai dengan 535 Ωm. Pendugaan rembesan lindi mulai menyebar pada kedalaman 0,5 meter dari permukaan yang mengalir ke bawah tanah dan terakumulasi pada kedalaman 89,5 meter. Nilai resistivitas lindi berkisar 0,242 Ωm – 7,6 Ωm dan diduga terakumulasi pada lempung pasiran.
