Abstract

keberadaan gua dengan berbagai fungsinya perlu dipelajari terutama terkait dengan karakteristik gua. Kenampakan morfologi dan tingkatan lorong gua dapat digunakan untuk memahami karakteristik gua tersebut. Penelitian ini bertujuan untuk mengidentifikasi morfologi dan tingkatan lorong Gua Banyu dan sekitarnya di Kecamatan Donomulyo, Kabupaten Malang. Penentuan kenampakan morfologi dilakukan dengan mengidentifikasi penampang melintang dan perhitungan kuantitatif. Sementara tingkatan lorong gua diukur dengan analisis frekuensi panjang lorong gua. Hasil penelitian menunjukkan morfologi yang terdapat di Gua Banyu dan sekitarnya didominasi perkembangan semicercular, yang diikuti perkembangan runtuhan maupun canyon. Sedangkan tingkatan lorong gua memiliki empat tingkatan. Tingkatan pertama terdapat di chamber Gua Sio dan sungai bawah tanah Gua Sio. Tingkat kedua ditandai munculnya mulut gua yang lain (Gua Kirek, Gua Maron, dan Gua Megarsari). Tingkatan ketiga terdiri dari lorong Gua Kirek, Gua Maron, Gua Megarsari, dan Gua Banyu yang telah berkembang. Sedangkan mulut Gua Banyu terlihat pada tingkatan keempat.

Abstract

Bagus-Jebrot Cave is located in Donomulyo District, Malang Regency which is in the Wonosari Formation which was formed in the Middle Miocene and Late Miocene. The purpose of this study is related to the developmental control that affects the cave passageways. The approach used is a geomorphological approach by conducting field measurements and documentation. The analysis used is frequency analysis and cross-section of the passage. Bagus-Jebrot Cave is a type of Epigenic Cave which is formed from surface water flowing into doline/sinkhole. It can be seen from the planview map that has a curvilinear passage pattern. The existence of groundwater flow also forms a physiographic cave passage with ellipse passage formation, asymmetrical ellipse, potholes, callops, solution notches, cups, solution pockets. Besides underground water flow, the development of the Bagus-Jebrot Cave aisle is related to the process of structural lifting and control. The lifting process is marked by the formation of 4 levels of the cave passage. While the formation of the canyon, joint passage, rectangular passage and keyhole is the result of structural control

Abstract

The cave passage is a natural form that develops in karst area. The cave passage is the sign of karst development. Mbah Wajib cave is located in southern mountains of Malang regency. There are certainly few studies of it, so the aim of this study is to find out the characteristics of the passage and the potential existed in this cave. Geomorphological approach became important in identifying the characteristic and the potential of this cave. Speleomorphology analysis and surface topographic features identification were used to get information related to the surface and subsurface. Morphometric analysis was used to show the dimension and levels of the cave passage. Cave passage interpretation was used to get the patterns developed on the cave passage. The measurement result in the field showed that the condition of Mbah Wajib cave passage is dominantly wide in shape rather than high. Meanwhile, the cave morphometric analysis showed that the cave is in unconfined condition. The morphometric index showed that the cave has a large complexity with a combination of vertical and horizontal passages. The development of the cave passage is dominated by structural and hydrological control which is adjacent to the rock layers. Water flow input comes from closed basins or ponds that assemble inside the cave. The development of cave level showed that there are three levels; first, a phreatic passage; the second level is an epiphreatic condition which is a fluctuation in the groundwater level; the third level is developing a vadose passage
