Abstract

Kota Semarang merupakan salah satu kota metropolitan yang berada di utara Pulau Jawa dengan jumlah penduduk mencapai 1,6 juta jiwa. Perkembangan kepadatan penduduk cenderung berdampak pada kebutuhan air bersih yang semakin meningkat. Saat ini hampir 80% kebutuhan air bersih di Kota Semarang diperoleh dari air tanah. Tujuan penelitian ini adalah menentukan karakteristik air tanah di Kota Semarang. Metode penelitian menggunakan analisis data isotop stabil 18O dan 2H dan kimia air melalui perhitungan nilai Chlorite Bicarbonate Ratio (CBR) dan analisis diagram Piper. Sampel air tanah yang digunakan mencapai 30 sampel. Litologi daerah penelitian berupa aluvium dan batupasir. Hasil penelitian diperoleh tipe air tanah di daerah penelitian terdiri dari tipe air NaHCO3, NaCl, CaHCO3, Na2SO4, dan MgHCO3 dengan tingkat pengaruh air laut dibedakan dalam 3 kelompok yang mencakup air tanah terintrusi sedikit-sedang, air tanah terintrusi agak tinggi, dan air tanah terintrusi tinggi. Analisis isotop 18O dan 2H menunjukkan bahwa air tanah di daerah penelitian dibagi menjadi 3 kelompok yaitu Kelompok I (18O -4, 585‰), Kelompok II (18O -5,070 ‰) dan Kelompok III (18O -5,451 - -6,044‰) serta memiliki nilai d-excess positif yang sebagian besar nilainya >10.

Abstract

Kelapa Kampit is one of the tin-producing districts in East Belitung, which is composed of the Kelapa Kampit Formation. This mining activity affects water quality, which, of course, is also influenced by geological formations. This study aims to analyze the hydrogeochemistry and heavy metals in shallow groundwater in Kelapa Kampit District using water quality indexes in the form of water quality index and heavy metal pollution index methods. Hydrogeochemical test results showed a pH value of water 4 – 6.77 in the acidic category, a DHL value of 20 – 145 μS/cm, and a TDS value of 14 – 111 mg/L. From the visualization of chemical data, groundwater has various facies. The results of the Stiff Diagram show that water contains predominant calcium, magnesium, sulfate, and bicarbonate ions. The Gibbs diagram results show that the water has not been contaminated. The results of heavy metal testing also showed that the values of Fe2+, Mn2+, Pb2+, Zn2+, and Cu2+ were classified as low, and Al3+ was quite high. The results of water quality testing using the water quality index showed that the research area had excellent water quality, and the results of the heavy metal testing using the HPI method showed a low heavy metal contamination value. Based on hydrogeochemical and heavy metal analysis of shallow groundwater, Kelapa Kampit District has good groundwater quality for sanitation hygiene purposes.
