Abstract
Ekplorasi sumber daya air perlu terus dilakukan demi
memenuhi kebutuhan hidup masyarakat. Kabupaten Bojonegoro
diketahui sebagai Kabupaten yang sering mengalami kesulitan air
di beberapa sub bagian daerahnya, terutama saat musim kemarau.
Penelitian mengenai potensi sumber air dilakukan sebagai
tindakan awal dalam upaya identifikasi keberadaan sumber daya
air.
Dari sisi ilmu penginderaan jauh, identifikasi potensi
sumber daya air dilakukan dengan pengamatan kerapatan vegetasi
dari hasil olahan citra satelit Landsat 8, terutama citra keluaran
bulan Mei hingga September 2014. Data pendukung yang
digunakan sebagai validasi dan pembanding terdiri atas data
geologi dan hidrogeologi, diolah bersama data primer
menggunakan metode overlay dengan bantuan Sistem Informasi
Geografis. Dari penelitian ini, dihasilkan data zonasi berupa Peta
Potensi Air Tanah Kabupaten Bojonegoro dalam 4 kelas potensi
debit air tanah, yaitu Tinggi (> 10 liter/detik), Sedang (± 5
liter/detik), Rendah (± 2.5 liter/detik), dan Langka (< 2.5
liter/detik).
Potensi kemunculan mata air teridentifikasi berada di
kawasan dataran tinggi dengan akuifer produktif yang terpotong
oleh patahan-patahan geologi. Terkecuali pada lahan vegetasi
yang telah berubah menjadi lahan terbangun, tingkat kerapatan
vegetasi yang konsisten di kawasan Kabupaten Bojonegoro
memiliki korelasi terhadap keberadaan sumber daya air sebesar
0.73 berdasarkan titik sampel yang dipilih, di mana angka tersebut
masuk pada kriteria korelasi positif kuat. ========== Exploration and exploitation of the water resources needs to
be done in order to meet the needs of society life. Bojonegoro
known as water shortage area in some of the sub-region, especially
in the dry season. A research study of potential water resources
are held as an initial action in effort to identify and search the
existence of water resource.
From the remote sensing point of view, water resources
potential are identified by analyzing the proportion of vegetation
based on processed Landsat 8 satellite imagery, particularly for
acquired image from May to September in 2014. The secondary
data have a role as validator dan comparator which consists of
Geological and Hydrogeological data, were processed along with
the primary data by using overlaying method of the Geographic
Information System. By doing this research, the potential zone can
be shown as Groundwater Potential Maps of Bojonegroro and also
classified in 4 class debit rate of groundwater flow, including High
(> 10 liter/sec), Medium (± 5 liter/sec), Low (± 2.5 liter/sec), and
Rare (< 2.5 liter/sec).
The potential zone of the natural appeared spring are
identified at the highland of the district where a lot of productive aquifer are crossed by geological fault. With an exception of the vegetation landcover that change into urban area, the quite consistent proportion of vegetation landcover has the corresponding correlation to the existence of the water resource by value of 0.73 (according to the choosen sample point) which it is classified as strong correlation.
