ANALISIS TINGKAT KESADAHAN DAN PH AIR SUMUR BOR DI DESA SEMIN, KECAMATAN SEMIN, KABUPATEN GUNUNGKIDUL. 1951600011

Air sebagai sarana peningkatan derajat kesehatan masyarakat perlu dijaga kualitasnya agar tetap bermanfaat bagi kehidupan manusia dan makhluk hidup lainnya serta dilakukan pengendalian air. Persyaratan kualitas air bersih telah diatur dalam Permenkes No. 416 Tahun 1990 tentang Persyaratan dan Pengawasan Kualitas Air. Tujuan dari penelitian ini adalah menganalisis kualitas air dengan parameter kesadahan dan pH untuk higiene dan sanitasi air yang digunakan oleh masyarakat desa Semin kecamatan Semin kabupaten Gunungkidul. Hasil pengujian menunjukkan bahwa tingkat kekerasan tertinggi terdapat pada sampel C3 yaitu 228,86 mg/L dan tingkat kekerasan terendah terdapat pada sampel A2 yaitu 89,55 mg/L. Hasil uji pH tertinggi terdapat pada sampel D3 yaitu 8,1, sedangkan kadar pH terendah terdapat pada sampel A2 yaitu 6,5. Berdasarkan hasil pengujian, air sumur bor di Desa Semin, Kecamatan Semin, Kabupaten Gunungkidul masih layak digunakan untuk keperluan higiene dan sanitasi.
