Analysis of Leachate Delineation of TPA Gampong Jawa Based on 2D Resistivity Modeling Using Geoelectric Method

Penanggulangan sampah di Indonesia dilakukan secara konvesional, yaitu sampah diletakkan di tempat terbuka yang jauh dari pusat kota dan dibiarkan membusuk dengan sendirinya. Namun penumpukan sampah tersebut dapat mengakibatkan terjadinya rembesan lindi di bawah permukaan yang sangat membahayakan ba...
