Abstract
ABSTRACT The rise of drinking water demand is not followed by the raw water supply, such as surface water, rainwater, and groundwater which are caused by the development and land-use change that usually ignore the preservation of the surrounding ecosystem. The purpose of this research is to know about the groundwater quality as a result of seawater intrusion at Genuksari Village, Genuk District, Semarang City, Central Java Province and to know the spread of seawater in unconfined aquifer. The determination of sampling point location uses purposive sampling method which is based on flow net map. The parameters that are used to measure the groundwater quality are TDS, TSS, DHL, pH, Chloride, and Sodium. The result of this research is adjusted to the standard quality of The Minister of Health Regulation No. 492 Year 2010 regarding The Requirements for Drinking Water Quality. Based on DHL and TDS parameters, there are 2 zones in this research area such as prone zone which has been intruded by seawater and safety zone which has not been intruded by seawater. Based on Chloride, pH, and Sodium parameters, it has not passed The Minister of Health Regulation No. 492 Year 2010 regarding The Requirements for Drinking Water Quality. Keyword : Seawater Intrusion, Groundwater, Drinking Water Quality INTISARI Peningkatan kebutuhan air minum tidak diiringi dengan ketersediaan air baku baik air permukaaan, air hujan, maupun air tanah yang diakibatkan oleh pembangunan dan perubahan tata guna lahan yang sering mengabaikan atau mempertimbangkan kelestarian ekosistem di sekitarnya. Tujuan penelitian ini adalah untuk mengetahui kualitas air tanah akib at adanya intrusi air laut di Desa Genuksari, Kecamatan Genuk, Kota Semarang, Provinsi Jawa Tengah dan mengetahui persebaran air laut pada akuifer air tanah bebas. Penentuan lokasi titik sampling menggunakan metode purposive sampling berdasarkan peta aliran air tanah. Parameter yang digunakan untuk menentukan kualitas air tanah adalah TDS, DHL, pH, Khlorida, dan Natrium. Hasil penelitian kualitas air tanah be bas disesuaikan dengan baku mutu Peraturan Menteri Kesehatan No. 492 Tahun 2010 Tentang Persyaratan Kualitas Air Minum. Berdasarkan parameter DHL dan TDS di daerah penelitian terdapat 2 zona yaitu zona rawan dimana telah terintrusi oleh air laut dan zona aman yakni belum terintrusi oleh air laut. Berdasarkan parameter Khlorida, pH dan Natrium belum melampaui Peraturan Menteri Kesehatan No. 492 Tahun 2010 Tentang Persayaratan Kualitas Air MInum. Kata Kunci : Intrusi air laut, Air tanah bebas. Kualitas air minum
