Abstract

Abstrak Air merupakan kebutuhan pokok bagi manusia. Air tanah salah satu alternatif sebagai sumber air bersih. Penelitian ini bertujuan untuk menyelidiki potensi air tanah di Perumahan Grand Puri Bunga Nirwana, Jember. Penelitian menggunakan metode geolistrik dengan konfigurasi wenner. Panjang lintasan akuisisi data 410 meter. Jarak spasi antar elektroda (a) yang digunakan yaitu 5 m, 10 m dan 15 m. Pengulangan data (n) dilakukan sebanyak 6 kali pada masing-masing jarak spasi antar elektroda. Inversi model menggunakan software Res2Dinv. Hasil inversi berupa citra penampang lapisan bawah tanah. Nilai resistivitas yang diperoleh 0,55-371 „¦m. Potensi air tanah berada di kedalaman 38-51,8 m. Akuisisi data terletak pada koordinat 8º10,2940 S dan 113º447,20 E. Lapisan akuifer tergolong akuifer produktif sedang. Debit akuifer diprediksi kurang dari 5 liter/detik. Kata kunci: geolistrik, wenner, resistivitas, akuifer Abstract Water is a primary human need. Groundwater is an alternative source of fresh water. This research aims to investigate the potential of groundwater at the Grand Puri Bunga Nirwana Housing, Jember. The study used the geoelectric method with a Wenner configuration. The acquisition data length is 410 meters. The distance between the electrodes used 5 m, 10 m and 15 m. Repeating data 6 times at each spacing between electrodes. Inversion of the model using Res2Dinv software. The inversion results in the form of a cross-sectional image of the underground layer. The resistivity value obtained 0.55-371 Ωm. The depthof groundwater potential is 38-51.8 m. Coordinates of data acquisition are 8º10.29'40 'S and 113º44'7.20' 'E. Aquifer layers are classified as medium productive aquifers. The predicted discharge of aquifer is less than 5 liters/second. Keywords: geoelectric, wenner, resistivity, aquifer

Abstract

Abstrak Bencana kekeringan di DAS Bedadung terindikasi dengan tidak terpenuhinya kebutuhan masyarakat akan pasokan air. Kekurangan air akibat defisit curah hujan menjadi indikator kekeringan meteorologi. Penelitian ini bertujuan untuk mendapatkan nilai indeks kekeringan di DAS Bedadung kabupaten Jember. Metode Standardized Precipitation Index (SPI) digunakan untuk mendapatkan tingkat kekeringan. Tingkat kekeringan meteorologi yang dihitung tergantung jumlah curah hujan yang terukur pada alat penakar di stasiun. Hasil penelitian ini menunjukkan bahwa indeks kekeringan ekstrim terjadi pada tahun 2018 dan 2019. Nilai indeks kekeringan (SPI-6) memiliki nilai tertinggi sebesar -2,69 di stasiun Ajung dan nilai     -1,13 di stasiun Kottok. Hasil pemetaan sebaran indeks kekeringan memiliki kesesuaian dengan kondisi kekeringan observasi. Hal ini ditunjukkan dari nilai validasi sebaran kekeringan antara SPI-6 dan data kekeringan observasi dengan tingkat keandalan sebesar 82%. Kata kunci: DAS Bedadung, bencana kekeringan, indeks kekeringan meteorologi, SPI   Abstract Drought disaster in the Bedadung watershed is indicated by the unfulfilled sociaty needs for water supply. Lack of water due to deficit in rainfall is an indicator of meteorological drought. This study aims to obtain the drought index value in the Bedadung watershed, Jember district. The Standardized Precipitation Index (SPI) method is used to obtain the drought saverity index. The meteorological drought index depends on the amount of rainfall observed on the rainfall gauge stations. The results of this study indicated that extreme drought index occurred in 2019. The drought index value (SPI-6) had the highest value of -2.69 at the Ajung station and a value of   -1.13 at the Kottok station. The results of the mapping of the distribution of the drought index are suitable with drought existing conditions. This is indicated by the validation value of the drought distribution between SPI-6 and the observed drought data with a reliability level of 82%. Keywords: Bedadung watershed, drought disaster, meteorological drought index, SPI
