The intensity of groundwater extraction, each year has increased along the
various factors that contribute to it. Therefore, the management of the utilization of
groundwater resources is an important step in the effort to preserve and maintain
the sustainability of the potential of groundwater in the basin in Indonesia, one of
which is the Subang Groundwater Basin in Subang district.
The study was conducted to determine the hydrogeological conditions, by
examining the wells (boreholes and wells) around Subang Groundwater Basin, and
determine the zoning of recharge area in Subang Groundwater Basin, with
reference to the book Kumpulan Panduan Teknis Pengelolaan Airtanah (PLG,
2007), namely by scoring.
From the results of correlation some drill logs, it in found out that in the
Subang Groundwater Basin area there are 2 aquifer systems, that is : unconfined
aquifer system and semiconfined aquifer system. Data from wells in the unconfined
groundwater level flow map, and the map of the known direction of groundwater flow
in Subang Groundwater Basin, from the direction of the southern part to the northern
part of Subang Groundwater Basin. Likewise with more catchment areas located in
the south of Subang Groundwater Basin than central and northern regions of
Subang Groundwater Basin.
Determination of Subang Groundwater Basin (Anonymous, 2007), based on:
1) passing the rock; 2) rainfall; 3) soil cover; 4) slope; 5) unconfined aquifer flow.
Each parameter has a ranking value from 1 to 5. The ranking value assessment is
carried out by making a grid of 2.5 cm x 2.5 cm on the Subang Groundwater Basin
map, then each grid is ranking value according to the circumstances of each
parameter. Then the ranking value of each grid of each parameter included in the
recharge value formula.
Then the results are colored in accordance with the provisions. From the
map classification (Zoning) it could be concluded that in the southern and central
part of Subang Groundwater Basin categorized in the Main Recharge Area, and in
the northern part of Subang Groundwater Basin categorized in the Additional
Recharge Area. |

Penelitian ini dilakukan di Cekungan Airtanah Subang yang ada di wilayah Kabupaten Subang dengan tujuan untuk mengetahui kondisi hidrogeologi, dengan cara meneliti sumur-sumur (sumur bor dan sumur gali) di sekitar CAT Subang, dan menentukan zonasi daerah imbuhan di CAT Subang, dengan mengacu pada buku Kumpulan Panduan Teknis Pengelolaan Airtanah (PLG, 2007), yaitu dengan cara scoring. Hasil korelasi beberapa log bor, didapat bahwa di daerah CAT Subang terdapat 2 sistem akuifer, yaitu sistem akuifer tidak tertekan dan sistem akuifer semi tertekan. Dari data sumur gali di dapat peta aliran airtanah akuifer tidak tertekan, dan dari peta tersebut diketahui arah aliran airtanah yang ada di CAT Subang, yaitu dari arah bagian selatan CAT Subang menuju bagian utara CAT Subang. Begitu juga dengan daerah resapan lebih banyak berada di daerah selatan CAT Subang dibanding daerah tengah dan utara CAT Subang. Penentuan zonasi kawasan imbuhan (Anonim, 2007) didasarkan pada: 1) kelulusan batuan; 2) curah hujan; 3) tanah penutup; 4) kemiringan lereng; 5) muka airtanah tidak tertekan. Masing-masing parameter mempunyai bobot nilai dari bobot nilai 1 sampai bobot nilai 5. Penilaian dilakukan dengan cara membuat grid 2,5 cm x 2,5 cm dari peta CAT Subang skala 1 : 100.000. Selanjutnya masing-masing grid diberi bobot nilai sesuai dengan keadaan dari masing-masing parameter. Bobot nilai dari masing-masing grid dari tiap parameter dimasukkan ke dalam rumus Nilai Imbuhan. Dari peta pengklasifikasian (Zonasi) dapat disimpulkan bahwa di bagian selatan dan bagian tengah CAT Subang termasuk dalam Daerah Imbuhan Utama, dan di bagian utara CAT Subang termasuk ke dalam Daerah Imbuhan Tambahan. |
