Abstract
Permasalahan yang sering dihadapi dalam mengelola sumber daya air ini adalah penurunan kualitas air. Salah satu indikator penurunan kualitas lingkungan yang sangat umum adalah menurunnya kualitas air yang biasa disebut dengan pencemaran air. Akibat dari adanya berbagai aktivitas yang berbeda-beda akan menghasilkan limbah yang berbeda pula, sehingga akan mempengaruhi kualitas airtanah. Daerah penelitian berada di Desa Gunung Gajah dan sekitarnya yang terletak di Kecamatan Bayat, Kabupaten Klaten, Provinsi Jawa Tengah, dengan luas wilayah penelitian yaitu 211,31 Ha. Tujuan dari penelitian ini yaitu untuk mengetahui dan mengkaji kualitas airtanah pada daerah penelitian, mengetahui pengaruh aktivitas pertanian dan permukiman pada daerah penelitian terhadap kualitas air dan mengetahui arah persebaran airtanah pada daerah penelitian. Metode penelitian yang digunakan dalam penelitian ini adalah metode survey lapangan dan analisis laboratorium. Adapun parameter untuk mengetahui karakteristik dari kualitas airtanah yang berasal dari sumur, sungai dan mata air di daerah penelitian maka dilakukan analisis kandungan Nitrat (NO3), Nitrit (NO2), Besi (Fe), Ammonia (NH3), pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) dan Escherichia coli (E. coli). Dianalisa berdasarkan PERMENKES RI No. 492 Tahun 2010 dan Peraturan Pemerintah RI No. 82 Tahun 2001. Hasil yang didapat yaitu dari beberapa titik sampel airtanah tercemar oleh Nitrat (NO3), Nitrit (NO2), BOD, COD dan bakteri E.coli. Sedangkan air permukaan tercemar oleh Nitrit (NO2), BOD, COD dan bakteri E.coli. Kualitas airtanah dan air permukaan pada daerah penelitian dipengaruhi oleh adanya pembuangan limbah rumahtangga yang langsung ke dalam tanah dan badan sungai tanpa pengelolaan yang baik; penggunaan pupuk, herbisida dan insektisida serta banyaknya pembangunan toilet yang berdekatan dengan sumur. Arah persebaran airtanah pada daerah penelitian mengarah ke Barat Laut. Kata Kunci : Kualitas, Airtanah, Bayat The issue which is often faced in managing water resources is declining quality of water. One of the indicators of environmental degradation is generally declining water quality which is often called water pollution. Various activities produce different kinds of waste, influencing the quality of ground water. Research area was Gunung Gajah Village and the surrounding area in Bayat, Klaten Regency, Central Java Province with total area 211,31 Ha. The purpose of this study was to discover and study the quality of ground water in the research area, to discover the influence of agricultural and household activities on the quality of water and to discover the direction of ground water distribution in the research area. The research methods used in this study were field survey and laboratory analysis. While the parameters to discover the characteristics of the quality of ground water from wells, rivers and springs in the research area were Nitrate (NO3), Nitrite (NO2), Iron (Fe), Ammonium (NH3), pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Escherichia coli (E. coli) contents. They were analyzed based on the Regulation of Minister of Health of Republic of Indonesia No. 492 of Year 2010 and Government Regulation of Republic of Indonesia No. 82 of Year 2001. The result was in some sample, ground water was polluted by Nitrate (NO3), Nitrite (NO2), BOD, COD and E.coli bacteria. While surface water was polluted by Nitrite (NO2), BOD, COD and E.coli bacteria. The quality of ground water and surface water in the research area was influence by the disposal of household waste directly to the soil and rivers without proper management; the use of fertilizers, herbicides and insecticides as well as construction of toilets near wells. The direction of the distribution of ground water in the research area is to Northwest. Keywords :Quality, Ground water, Bayat
