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.
