Abstract


Penelitian ini bertujuan untuk: (1) menganalisis karakieristik geomorfologi dan
satuan-saiuan beniuklahan di daeran peneliiian, (2) menganalisis karakteristik bawah
permukaan (subsurface) di daerah peneliiian, dan (3) mengkaji hubungan aniara karakteristik
geomorfologi dengan karakieristik bawah permukaan (subsurface) di daerah penelitian. Kajian
karakteristik geomorfologi dan. saiuan-saiuan bentuklahan di daerah penelitian dilakukan
berdasarkan interpretasi citra sate/it multi resolusi, interpretasi peta RBI, dan survei lapangan.
Berbagai teknik penajaman citra diterapkan untuk memperjelas kenampakart geomorfologikal
pada citra sate/it. Delineasi satuan bentuklahan dilakukan secara on-screen dengan
menggunakan Sistem Informasi Geografi (SIG). Proses penghalusan delineasi satuan
bentuklahan dilakukan dengan mempertimbangkan analisis pola kelurusan, pola aliran, dan pola
penggunaan lahan yang ada pada citra sate/it dan analisis pola kontur pada peta RBI digital.
Informasi mengenai materi penyusun bentuklahan beseria struktur geologi yang menyertainya
diperoleh dari pembacaan peta geologi. Kajian karakteristik bawah permukaan (subsurface)
dilakukan dengan analisis geofisika, analisis data bor dan survei lapangan. Analisis hasil
penelitian dilakukan. secara deskriptif dan secara spasial atas obyek yang diteliti. Hasil 'peneliiian
menunjukkan bahwa morfologi daerah Bantu! dapai diklasifikasikan sebagai dataran, perbukiian,
dan pegunungan. Bentuklahaii secara umum di Bantu/ terdiri dari 6 bentukiahan berdasarkan
genesisnya, yaitu: jluoial, marine, aeolian, solusional, denudasional, dan struktural. Selain itu,
struktur bawah permukaan daiaran rendah Bantu/ berupa asimetris graben. Kedalaman basemen
graben bervariasi hingga 1,6 km. Kedalaman sedimen bervariasi antara 3 - 150 m. Sedimen
alluvium tebal yang tidak terkonsolidasikan menempati bagian timur dataran aluvial yang dekat
gawir dan. Pegunungan Baturagung. Sedimen alluvium dangkal yang tidak terkonsolidasikan
menempati bagian bagian barat daiaran aluvial dekat bukit sisa dan perbukitan denudasional.
Kedalaman muka airtanah dangkal menempati beniuklahan. fluvial, marine, dan aeolian.
Sebaliknya, Kedalaman muka airtanah dalam menempaii bentuklahan denudasional, sirukiural,
dan solusional. Selain itu, bentuklahan fluvial, marine, dan aeolian memiliki nilai kerapatan
(densitas) batuan rendah, yang menunjukkan material penyusun tebal yang tidak
terkonsolidasikan berupa alluvium Kuarter ..
