Abstract: Has been conducted a research on The Analysis of Sea Water Instrution on Digging Well and Bore Well with Electricial Conductivity Method in Hamparan Perak Sub-district. The sample of wells was collected from 22 points of bore wells and 20 points digging wells in 5 villages, each is collected for the amount of 600 ml. From the laboratory test on the digging well, for the value of DHL ( 303 – 2234) μmho/ cm, 25ºC, Cℓ (4,85 – 809, 4) mg/ℓ, TDS (214 – 1945)mg/ℓ and for bore well the value of DHL (181 – 2230)μmho/ cm, 25ºC, Cℓ (4,85 –1235, 4) mg/ℓ, TDS (470 – 1910)mg/ℓ. Based on those values, using Surfer 7 Program then the surface intrution spread-out was made. To analyse the range factor, depth and Cl towards DHL, SPSS 18 Program is used. From DHL values, all 20 points of digging wells as samples have already been intrutiated by sea water and for bore wells in 21 points of samples have been intrutiated from the fewest level to the highest one.
Abstract (other language): Telah dilakukan penelitian tentang intrusi air laut pada sumur bor dan sumur gali dengan metode konduktivitas listrik di wilayah Kecamatan Hamparan Perak. Sampel air sumur diambil sebanyak 22 titik sumur bor dan 20 titik sumur gali pada 5 desa,masing-masing sebanyak 600 ml. Dari hasil pengujian Laboratorium untuk sumur gali nilai DHL (303-2234) μmho/cm,25ºC, Cl (4,85-809,4) mg/l,TDS (214-1945) mg/l,untuk sumur bor nilai DHL (181-2230) μmho/cm,25ºC,Cl(4,85-1235,4) mg/l,TDS (170-1910)mg/l.Berdasarkan nilai tersebut dengan program surfer 7 dibuat kontur sebaran intrusi. Untuk menganalisa faktor jarak, kedalaman,dan konsentrasi klorida digunakan program SPSS 18. Dari nilai DHL,untuk sumur gali dari 20 titik sampel semua air sumur telah terintrusi air laut dan untuk sumur bor 21 titik sampel air sumur telah terintrusi,mulai dari tingkat terintrusi sedikit sampai terintrusi tinggi.
