Dampak yang terjadi dari operasi penambangan adalah lahan menjadi tidak produktif serta tingkat erosi yang sangat tinggi karena vegetasi di atas lahan bekas penambangan telah hilang. Hal tersebut yang mempengaruhi kepekaan tanah untuk bertahan terhadap penghancuran dan pengangkutan oleh hujan dan aliran permukaan serta terjadinya longsoran. Analisis faktor erodibilitas tanah dilihat dari sifat fisik-kimia tanah yang menjadi salah satu penyebab erosi dengan menggunakan parameter unsur organik, struktur tanah, permeabilitas, tekstur. Lokasi observasi dilakukan pada lereng disposal dan low wall in pit yang telah di revegetasi dengan teknik hydroseeding. Penelitian ini dilakukan dengan membuat desain plot erosi dan sedimentasi berbentuk kotak dengan pembatas seng ukuran 2 x 2 m2, dimana setiap kotak dibagi menjadi 3 kolom. Pembagian 3 kolom pada setiap kotak dilakukan untuk mendapatkan data pengulangan yang representative. Pengambilan sample tanah dilakukan di setiap kotak dengan menggunakan ring sample.

The present study was aimed to identify the kaolin minerals and to understand the development of the kaolin/smectite mixed layer. Clay fraction samples were collected from the Paleudult profile. Selective dissolutions using dithionite citrate bicarbonate, NaOH, and Na-citrate treatments were conducted on the clay fraction. The result showed that free iron oxide content increased with the depth. Halloysite which showed a 7.6 Å peak on the X-ray diffraction (XRD) was confirmed by the hot NaOH extraction. SiO 2 /Al 2 O 3 molar ratio from the hot-citrate extracts provided the halloysitic property only in the upper horizons. However, the peaks of 10-14 Å on the XRD collapse at 300 o C following the hot citrate treatment suggesting that crystallinity of the halloysite mineral is weak. This halloysite mineral developed well in the upper horizons. The development of halloysite/smectite mixed layer is proposed in the four stages.

The study was aimed to determine the potential of the soil and evaluate the suitability of the land for sweet sorghum (Shorgum bicolor) crop in Gunung Kelir, Pleret District, Bantul, Yogyakarta as part of the Opak Fault line. A total of 20 sample points were collected based on geological data, land use, slope, and administrative maps. Analysis of soil physical and chemical properties was carried out to classify soil types and land suitability for sweet sorghum plants. The developing soils in the study area were originated from volcanic breccias, Young Merapi Volcano, and the alluvial of the Opak River, with included in orders of Entisols and Inceptisols. The cation exchange capacity of soils that develop from volcanic breccias is higher than those that develop from Merapi volcanic soils. Suitability of land for sweet sorghum plants includes S2 class with limiting factors for nutrient retention, temperature, and erosion hazard area of ± 24,011 Ha (76.23%), S3 class with limiting factors for erosion hazard and surface stonies of ± 3.85 Ha (12.22%), and N class with a root zone constraint of ± 0.139 Ha (0.44%), and others are not agriculture. Based on the results of this study it is expected that sweet sorghum is able to be developed in the Opak Fault zone to enhance the use of marginal land.

Stratigraphically this region was composed of volcanic breccia, andesite lava intruded by andesite and then undergoes hydrothermal alteration. The result of the interaction between hydrothermal fluids and rocks produce some heavy metals. The elements will be contained also on the soil which was the result of its weathering and then the heavy metal elements were absorbed by the plant. The elements with certain level were very dangerous for human health. This phytoremediation process can also occur in alteration rocks of Quaternary volcanoes. Then some plants will have different capabilities in absorbing certain heavy metals. This research was conducted to know the characterization of vegetable plants that absorb heavy metals and this research using methodology are: petrography, X-ray diffraction (XRD), X-Ray Fluorences (XRF) and mercury analysis using Mercury Survey meter. This methods were done to know the rocks type, alterations type and heavy metals content. The analysis yields andesitic rock type which is hydrothermally altered to argillic. These argillic rocks become soils containing heavy metals including Mn, Fe, Co, Cu, As, Hg and Pb. With the process of phytoremediation then heavy metals can be contained in plants. The results showed that vegetable plants have the character of absorbing certain heavy metals, such as: chilli (Capsium fruteceus) absorb Hg. Kale (Ipomoea aquatica), chilli, bay (Eugenia aperculata) leaf, papaya (Carica papaya) and taro (Colocasia esculenta) leaf are absorbed Fe element. It proves that the metallic minerals as result of hydrothermal alteration process are absorbed by plants or vegetables.

Most of these soils contain kaolin as the dominant clay mineral. Exchangeable aluminium (Al) generally balances permanent negative charges and occupies strongly acidic exchange sites of the soil clay. The objective of this study was to identify those clay minerals that are most highly implicated in contributing exchangeable Al to red and yellow soils collected from the Islands of Okinawa and Java. All soils exhibited an acid reaction but varied in their exchangeable Al content and clay mineralogy. Clay content was high in all Javan soils but varied in those from Okinawa. Javan soils were dominated by kaolinite, and Okinawan soils by an association of illite and halloysite. However, 2 : 1-2 : 1 : 1 intergrades were significant components in both the Oku red soils (Okinawa Island) and the Pamagersari red soils (Java Island). Javan soils were characterised by a more mature (advance...
