The Tingkat Kesadahan dan Uji Derajat Keasaman (pH) pada Air Tanah di Desa Mapane Tambu Kecamatan Balaesang Kabupaten Donggala

Research has been carried out on the level of hardness and the degree of acidity (pH) in groundwater in Mapane Tambu Village, Balaesang District, Donggala Regency. The purpose of this study was to determine the concentration of the water hardness level and the degree of acidity of the water, complexometric method was used to determine the level of water hardness using three samples and obtained the results of sample A 15.61 mg/L; sample B 9.40 mg/L and sample C 19.22 mg/L, with a total hardness level obtained an average value of 14.74 mg/L classified in the low hardness category. Then the degree of acidity (pH) was measured using the electrometric method with a (pH) meter with three variations of sample results and the results obtained were sample A 7.713; sample B 8,511; sample C 6.916. The determination of the degree of acidity (pH) of the water obtained in the three samples was in accordance with the regulation of PERMENKES Number 492/Menkes/Per/IV/2010 concerning the quality of clean water which was in the pH range of 6.5 - 6.8Telah dilakukan Penelitian Tingkat Kesadahahan dan Uji Derajat Keasaman (pH) pada Air Tanah di Desa Mapane Tambu Kecamatan Balaesang Kabupaten Donggala. Tujuan penelitian ini adalah untuk menentukan kosentrasi tingkat kesadahan air dan derajat keasaman air, metode kompleksometri digunakan untuk mengetahui tingkat kesadahan air dengan menggukan tiga sampel dan diperoleh hasil sampel A 15,61 mg/L; sampel B 9,40 mg/L dan sampel C 19,22 mg/L, dengan tingkat kesadahan total yang diperoleh nilai rata-rata sebesar 14,74 mg/L diklasifikasikan dalam kategori kesadahan rendah. Kemudian derajat keasaman (pH) diukur menguunakan metode Elektrometri dengan alat (pH) meter dengan tiga variasi sampel hasil dan diperoleh hasil sampel A 7,713; sampel B 8,511; sampel C 6,916. Penentuan derajat keasaman (pH) air yang diperoleh pada tiga sampel sesuai dengan aturan PERMENKES Nomor 492/Menkes/Per/IV/2010 tentang kualitas air bersih yang berada pada kisaran pH 6,5 - 6,
