Abstract

fetched live from OpenAlex

Sebuah studi kasus telah dilakukan untuk membuatzona potensi airtanah di daerah sekitar PantaiParangtritis, Provinsi DIY. Tujuan dari penelitianadalah untuk untuk memetakan zona potensiairtanah berdasarkan parameter airtanah yang dapatdisurvei di lapangan pada suatu daerah yangmemiliki variasi bentuklahan yangberagam. Interpretasi sebaran bentuklahan dimulaidengan menyiapkan data pendukung seperti PetaRupa Bumi Indonesia yang berisi informasi gariskontur dan data penggunaan lahan data, peta geologiregional untuk mengetahui kondisi litologi danstruktur geologi, data tanah, iklim, dan datahidrologis awal. Penentuan satuan bentuk lahandilakukan secara manual melalui interpretasi visualdari citra Digital Landsat ETM+ dengan beberapakunci interpretasi yang diperoleh dari data sekunderdan disurvei di lapangan. Selanjutnya dilakukanpengukuran parameter lapangan potensi airtanahyaitu (a) kedalaman muka airtanah, (b) ketebalanakuifer, dan (c) Daya Hantar Listrik (DHL) yangmewakili kualitas airtanah. Zonasi potensi airtanahdiperoleh dengan melakukan overlay semuaparameter lapangan airtanah dengan metode overlaytertimbang menggunakan alat analisis spasial SistemInformasi Geografi (SIG) pada perangkat lunakArcGIS 9.2. Pada proses overlay tertimbang,peringkat yang dihasilkan untuk setiap parameterindividu pada masing-masing parameter lapanganairtanah dibobot berdasarkan tingkat pengaruh yangmereka miliki terhadap potensi airtanah, yaitu,kedalamanan muka airtanah sebesar 35%, ketebalanakuifer sebesar 35%, dan DHL sebesar 30%. Hasilpenelitian menunjukkan bahwa dari seluruh luasanwilayah kajian yang diteliti, mayoritas potensiairtanah tergolong pada kelas baik (49,8%) dansedang (48,7%). Sementara itu, kelas miskin airtanahhanya menempati luasan yang sangat kecil, yaituhanya 1,5% dari total luas wilayah kajian. Sementaraitu, jika ditinjau tiap satuan bentuk lahan, makabentuklahan Beting Gisik mempunyai sebaran potensiairtanah yang paling luas (30,4%), yang disusul olehbentuklahan Dataran Aluvial (11%).

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
