    Abstract
    It had conducted a research on analysis of intrusion of sea water in to the dig and drill wells by electrical conductivity at sub district of Medan Marelam in order to study the intrusion level of sea water to the dig and drill wells by measurement of electrical conductivity of the dig and drill wells water. Sampling of sea water, dig and drill well water is begin from the reference point on the coastal line on the point of sea water and from the reference point from the coastal line to the well.. The research aims to study the influence of factors i.e. distance, depth and concentration of chloride to the intrusion of sea water, water content of dig and drill wells and the temperature of dig and drill water. Based on observation analysis is found that on the dig well, the distance, depth and concentration of chlorideto electrical conductivity is higher means that there is a positive and significant correlation between distance, depth and concentration of chloride simultaneously to the electrical conductivity for 73.2 ℅ while for the drill well, the value between distance, depth and concentration of chloride to electrical conductivity is lower means that there is a weak correlation between distance, depth and concentration of chloride to the electrical conductivity for 36.4 ℅
     
    Telah dilakukan penelitian mengenai analisa intrusi air laut pada sumur gali dan sumur bor dengan metode konduktivitas listrik dikecamatan Medan Marelan. untuk mengetahui tingkat intrusi air laut pada sumur gali dan sumur bor dilakukan dengan pengukuran Daya Hantar Listrik ( DHL ) air sumur gali dan sumur bor. Pengambilan sampel air laut, air sumur gali dan air sumur bor dimulai dari titik acuan dari garis pantai menuju titik air laut dan dari titik acuan dari garis pantai menuju kearah daratan yaitu sumur-sumur rumah penduduk . Tujuan penelitian ini adalah untuk mengetahui pengaruh faktor jarak, kedalaman dan konsentrasi klorida terhadap intrusi air laut, kandungan air sumur gali dan air sumur bor( TDS ) dan suhu air sumur gali dan sumur bor Dari analisis pengamatan dapat dilihat pada sumur gali nilai antara jarak, kedalaman dan konsentrasi klorida terhadap DHL cukup erat atau relative tinggi artinya terdapat hubungan yang positip dan kuat antara jarak,kedalaman dan konsentrasi klorida secara bersama sama terhadap Daya Hantar Listrik (DHL) sebesar 73,2℅ sedangkan pada sumur bor nilai antara jarak, kedalaman dan konsentrasi klorida terhadap DHL tidak erat atau relatif rendah artinya terdapat hubungan yang lemah antara jarak,kedalaman dan konsentrasi klorida terhadap Daya Hantar Listrik (DHL) sebesar 36,4℅
