    Abstract

    INTISARI Desa Karanggadung merupakan salah satu desa di kecamatan Petanahan, kabupaten Kebumen yang merupakan wilayah kepesisiran dengan jarak ± 300 meter ke arah Pantai Selatan Jawa atau Samudra Hindia, yang memiliki air tanah dangkal pada lahan permukiman daerah binting gisik serta lahan pertanian daerah swale. Penelitian ini bertujuan untuk mengetahui sebaran kualitas air tanah dangkal pada daerah gumuk pasir berdasarkan baku mutu air minum Peraturan Daerah Provinsi Jawa Tengah No.10 Tahun 2004 Tentang Baku Mutu Air Golongan A dan B. Metode yang digunakan dalam penelitian ini adalah dengan metode survey dan Metode Analisis Laboratorium, Sedangkan pengambilan sampel menggunakan metode Purposive Sampling. Sampling diambil berdasarkan bentuklahan, arah aliran muka air tanah sesuai keberadaan aktivitas pertanian dan permukiman. Sampel air tanah yang di teliti ada sepuluh sampel yang pengambilannya di sumur warga dan sumur bor. Data yang di perlukan yaitu data primer dan data sekunder. Data primer berupa hasil pengukuran langsung di lapangan, meliputi data tinggi muka air tanah dan data sifat fisik air tanah, data sifat kimia air tanah, dan data sifat biologi air tanah. Data sekunder berupa data yang didapat dari sumber yang telah ada yaitu instansi-instansi terkait dan data baku mutu untuk air minum. Berdasarkan hasil pengukuran langsung air tanah di lapangan secara fisik mempunyai warna air berwarna jernih, rasa air tawar, dan air tidak berbau. Semuanya masih sesuai dengan baku mutu air berdasarkan Peraturan Daerah Provinsi Jawa Tengah No.10 Tahun 2004 tentang Baku Mutu Air Golongan A dan B. Berdasarkan hasil uji laboratorium untuk pH, sampel airtanah pada titik satu sampai sepuluh bernilai 6.81 – 6.95 mg/l (asam) sesuai dengan baku mutu air. Untuk kadar Nitrit, Amonia, BOD, dan COD tidak melebihi baku mutu air, sedangkan kadar Nitrat berkisar antara 1.21 mg/l - 54.323 mg/l, ada beberapa titik yang melebihi baku mutu air. Untuk Jumlah bakteri Coliform Total di sepuluh titik sumur berkisar antara 3 MPN/100ml - ≥2400 MPN/100ml, angka ini tidak sesuai dengan Peraturan Daerah Provinsi Jawa Tengah No.10 Tahun 2004 tentang Baku Mutu Air Golongan A. ABSTRACT Karanggadung village is one of the villages in District Petanahan, Regency Kebumen, which is the area of coast with a distance of ± 300 meters toward the Southern coast of Java or the Indian Ocean, Which has a shallow groundwater at the land settlement areas as well as agricultural land gisik binting area swale. This research aims to determine the distribution of shallow groundwater quality in the sand dunes area is based on the quality of the raw water of Central Java Province Regulations No. 10 of 2004 about the raw water quality in group A and B. The methods used in this study is to survey methods and methods of analysis laboratory, while sampling using the method of purposive sampling. Sampling is taken on the basis of land forms, home of groundwater flow direction according to the agricultural activity and settlements. Sampels of groundwater in thoroughly there are ten samples that they were taken at the well drill wells and citizens. The data needed are primary date and secondry date. The date needed in the form of direct measurement, groundwater physical properties date, date on chemical properties of soil, water and biological properties of groundwater data. Secondry date are date obtained from existing sources related government establishments and raw quality for driking water Based on the results of the direct measurement of groundwater in field have physically clear colored water color, flavor, fresh water and the water doesn’t smell. Everthing is still in accordance with quality raw water based on rule of region of Central Java Province No.10 of 2004 about the raw water quality classes A and B. Based on test results for pH, laboratory samples of ground water at the point of one to ten worth 6,81 – 6,95 mg/l (acid) in accordance with the raw water quality of raw water, whereas with raw water quality. Nitrate levels range between to 1,21 mg/l -54,23 mg/l, there are several points that exceed the raw water quality. For the amount of Total Coliform in ten points wells ranged from 3 MPN/100ml - ≥2400 MPN/100ml, this number is not in accordance with the regulations of the Central Java area No.10 of 2004 about the raw water quality in group A.
