Abstract

TPA Ngipik dalam perencanaannya dibuat dalam bentuk Sanitary Landfill. Namun realita yang terjadi ialah penerapan sistem Open Dumping. Hal ini membuat pencemaran mudah terjadi baik pencemaran tanah, air dan udara. Penelitian ini berfokus pada pencemaran air tanah yang berupa resapan dan persebaran air lindi di bawah permukaan. Telah dilakukan pengukuran Resistivitas 2D Konfigurasi Wenner-Schlumberger sebanyak 7 lintasan pada musim kemarau dan musim penghujan untuk mengidentifikasi persebaran air lindi dan untuk mengetahui pola persebaran air lindi pada setiap musim. Pengukuran parameter air tanah dan uji resistivitas skala laboratorium juga telah dilakukan. Hasil pengolahan resistivitas 2D telah diverifikasi dengan hasil pengukuran parameter air tanah dan analisa resistivitas skala laboratorium untuk mendapatkan interpretasi kuantatif. Hasil penelitian menunjukkan bahwa dari 7 lintasan yang diteliti, 6 lintasan teridentifikasi adanya persebaran air lindi dan hanya lintasan 3 yang belum teridentifikasi persebaran air lindi. Nilai resistivitas hasil inversi yang diinterpretasikan sebagai sebaran air lindi ialah 0.1 – 1.5 Ωm. Persebaran air lindi memiliki pola dari Tenggara – Barat Laut mengikuti kontur evelasi muka air tanah. ============================================================================================= Ngipik Landfill in the planning will be made in sanitary landfill system. In the reality, that landfill uses open dumping system. This problem makes contamination occur easily, both pollution of soil, water and air. Seven acquisition lines geoelectrical measurement with wenner-schlumberger array have been done during the dry season and wet season to identify and to know the direction and pattern of leachate migration at each season. Groundwater parameter measurements and laboratory resistivity tests have also been performed. 2D resistivity inversion results have been verified with groundwater measurement and laboratory resistivity tests to obtain a quantitative interpretation. The results showed that of the 7 line measured, 6 line were identified a leachate migration and just 3rd had not been found a leachate migration. Resistivity value that interpreted to leachate migration is 0.1 – 1.5 Ωm. Leachate migration have direction from Southeast to Northwest following the contour of ground water elevation.
