Abstract

ABSTRACT. Along with the increment of human population, ground water pollution also tends to increase. It primarily due to the accumulation of waste which could harm the public health. Trash or waste is one of the important issues which could contaminate ground water, especially waste landfills. Ground water that has been contaminated with liquid waste (leachate) can affect the quality of ground water. This study aimed to determine the composition of rocks, layers and depth of ground water around waste landfills (TPS) and to determine whether ground water around the TPS is contaminated or not. Estimation of groundwater pollution could be determined by measurement using geoelectric method with schlumberger configuration. It showed  the presence of leachate layer at depth of 0,51 – 8,51 m with measured resistivity of 3,89 – 9,63 Ohm.meter, while groundwater is at depth of 22,92 – 26,59 m with resistivity value of 88,98 – 128,75 Ohm.meter. AAS sample test has been conducted to determine whether the ground water around TPS is contaminated or not.  The test results using AAS showed groundwater around TPS was contaminated with Lead (Pb), iron (Fe) and Cadmium (Cd). The evidence was the value of their concentrations in three water samples which exceeded the thresholds in accordance with the requirements of drinking water. Threshold for Pb, Fe and Cd are 0,01 ppm, 0,3 ppm and 0,003 ppm, respectively. From the measurement results of sample 1, 2 and 3 couls be obtained the concentration of  Pb are 0,084 ppm, 0,044 ppm and 0,091 ppm, the concentration of Fe are 0,812 ppm for 1,018 ppm and 0,203 ppm, while the concentration of Cd are 0,012 ppm, 0,017 ppm and 0,01 ppm. Keywords: Ground water, waste, geoelectric, AAS

Abstract

Telah dilakukan penelitian untuk mencari lapisan akuifer air tanah di Desa Sungai Jati sebagai dasar dalam perencanaan dalam pembuatan sumur bor. Salah satu cara untuk mengetahui potensi keberadaan air tanah adalah melakukan pengukuran geolistrik dengan konfigurasi schlumberger. Hasil penelitian  geolistrik  konfigurasi  schlumberger  menunjukkan  struktur  lapisan batuan di Desa Sungai Jati pada titik pengukuran GL1, GL2, GL3, GL4, GL5 dan GL6  terdiri  dari  lapisan  lapuk,  batu  pasir,  lanau,  lempung,  dan  lempung gampingan karena Sungai Jati termasuk kedalam formasi Keramaian (Kak). Sebaran akuifer air tanah tersebar pada lapisan batu pasir dengan  kedalaman akuifer air tanahnya bervariasi. Hasil interpretasi diketahui tebal lapisan berkisar antara  2 – 11  meter  dengan kedalaman  sekitar  6  –  40  meter  dengan  nilai resistivitas 100 – 450 Ωm. Secara keseluruhan semakin ke bawah jenis batuanya semakin padat, lapisan ini kurang bersifat sebagai lapisan pembawa air (akuifer). Lapisan air tanah yang berpotensi untuk pembuatan sumur bor dengan kualitas dan kuantitas yang cukup baik terdapat lapisan impermeable pada bagian atas dan bawah sedangkan pada Desa Sungai Jati merupakan akuifer bebas dimana lapisan impermeable hanya terdapat pada lapisan di bawah lapisan akuifer. Kata kunci : geolistrik, konfigurasi schlumberger, akuifer

Abstract

Ditinjau dari aspek geologis, geografis, dan morfologis, Kalimantan Selatan merupakan salah satu provinsi yang rawan terhadap bencana banjir. Hampir setiap tahun bencana banjir terjadi, khususnya di wilayah Kabupaten Banjar. Banjir yang terjadi akibat luapan Sungai Riam Kiwa, Sungai Riam Kanan dan Sungai Martapura. Sedikitnya 64 desa pada bulan Januari 2012 di enam wilayah kecamatan yang berada di sepanjang Sungai Riam Kiwa dan Martapura terendam banjir. Data Badan Penanggulangan Bencana Daerah (BPBD) Kabupaten Banjar menyebutkan, banjir yang melanda di Kecamatan Astambul merendam 17 desa dari 22 desa yang ada, dihuni oleh 1.985 Kepala Keluarga atau 6.000 jiwa. Salah satu penyebab timbulnya korban jiwa dan kerusakan/kerugian yang sering terjadi akibat bencana alam adalah karena masyarakat lalai dan tidak mengetahui bahwa daerah tempat tinggal mereka termasuk daerah yang rawan bencana banjir, serta kurangnya pengetahuan masyarakat tentang mitigasi dan kesiapsiagaan termasuk aparat/pihak-pihak yang bertanggung jawab dalam penanganan bencana. Untuk itu melalui kegiatan Pengabdian Pada Masyarakat merupakan upaya nyata kepada Masyarakat Kecamatan Astambul untuk mengurangi resiko bencana banjir antara lain dalam bentuk pelatihan dan pembinaan penanggulangan banjir. Kegiatan ini untuk memberikan informasi kepada masyarakat tentang daerah rawan banjir. Oleh karena itu dilakukan analisis daerah rawan banjir dengan sistem bobot menggunakan parameter curah hujan, bentuk lahan, gradient sungai, kerapatan drainase, kemiringan lereng dan penggunaan lahan. Dari hasil analisa tingkat kerawanan di Kecamatan Astambul, luas daerah yang masuk kategori sangat rawan sebesar 81.501,76 ha atau 17,94 % dari luas wilayah dan kategori rawan 62.506,37 ha atau 13,76 %
