This study aims to describe the characteristics of land in a landslide-prone area in Koto Parik Gadang Diateh, South Solok Regency. The design of this research is descriptive survey method, primary data obtained in the field and laboratory, and secondary data from references and literature analysis. This research technique is stratified random. Data analysis is land characteristics descriptively and tabulated criteria for determining physical phenomena in determining the level of landslide hazard. The results of the study explain: the characteristics of the land area there are 7 soil units, the level of landslide hazard, names: (1) the low level of landslide hazard contained in the VI.Qpt.I.Pem.Gleih land unit. (2) The level of landslide hazard is in the land units V3.Mip.III.Pem.Gleih and V4.Pckm.IV. Ht. Gleih. (3) a high level of landslide hazard is found in the V4.Mpip.IV land unit. Pem.Gleih, V4.Qal.IV.Pem.V, V4.Qube.IV. Pem.Gleih and V4.Pckm.V. Pkb.Gleih.
Kawasan Geopark Silokek memiliki potensi wisata dengan keunikan tersendiri yang dapat meningkatkan ekonomi masyarakat atau daerah di Kabupaten Sijunjung. Penelitian ini bertujuan untuk (1) mengidentifikasi potensi fisik di kawasan Geopark (2) menganalisis potensi geowisata Nagari Silokek. Pada penelitian berdasarkan klasifikasi yang disusun untuk kegiatan geowisata menggunakan metode skoring yang meliputi nilai ilmiah dan intrinsik, nilai edukasi, nilai ekonomis, nilai konservasi serta nilai tambahan lainnya. Kawasan geopark ini secara geologi sangat menarik karena Geopark ini telah melewati 3 (tiga) era dalam skala waktu geologi. Batuan tertua (Paleozoikum) yang diwakili oleh Formasi Kuantan (sebagian telah mengalami proses metaforfosa). Batuan era pertengahan (Mesozoikum) diwakili oleh intrusi magma yang berkomposisi granitic yang membentuk granit. Terkahir batuan muda (Kenozoikum) yang diwakili oleh batuan dari Formasi Ombilin. Berdasarkan kondisi geologi yang seperti ini pada kawasan Geopark Silokek memperlihatkan topografi yang bervariasi yaitu terbentuknya kawasan eksokarst dan endokarst.
This research was conducted in the Air Dingin watershed of West Sumatra which aim calculating changes of land cover area in Air Dingin watershed (2008 – 2021). To determine land cover changes using maximum likelihood classification by utilizing Arc Map 10.8. It can classify land cover change and Microsoft Excel software to calculate land cover change. The result shows that the landcover change of Air Dingin Watershed in 2008 - 2021 largest increase in the shrub area by 392.60 ha (3.1%) and followed by dry land agriculture which increased 215.18 ha (1.7 %), building area increased by 148.68 ha (1.2%), mixed gardens by 16.94 ha (0.1%). The increase in land area will be followed by a reduction in land cover, which has the largest decrease in forest area, namely 635.58 ha (5.0%), followed by a decrease in paddy fields of 129.25 ha (1.0%) , waters decreased by 8.57 ha (0.1%).
The existing settlement patterns in Indonesia are generally divided into three types, namely linear pattern, radial pattern and a pattern of concentric circles which exist and are influenced by factors of natural resources or fisiografi. The pattern of the village or settlement is a settlement in the distribution of the specificity of the phenomenon of space or territory, against the peculiarities are the forms individually as well as settlement spread from individual neighborhood clusters. Climate factors, the State of the soil, the water, topography, availability of natural resources as well as the population in a region made the distinctiveness or character on settlement patterns at a village/nagari/head, it is interesting to know the pattern of the spread of settlements Nagari Balah Aie Aie Balah Eastern Nagari and, using the research method used for this research is a descriptive qualitative approach to case studies (case study) of distinct physiographic Shaper settlement patterns that exist in nagari such. The research results obtained from the research field that is viewed and measured settlements are there in 2 (two) the nagari namely Nagari Balah Aie and Aie Balah Eastern Nagari and on aspects of the existing fisiografi and Non-Fisiografi, and count formulas nearest neighbor (T = Ju/Jh), with the result declared distribution pattern of settlement in Nagari Balah Aie Aie Balah Eastern Nagari and "Uniform forms of settlement patterns extends way".
