Abstract

The area of this research is in the Lintau Buo Region, Tanah Datar District, West Sumatra. Based on the regional geology, the location is on the boundary of the Ombilin Basin which has active tectonic conditions. This research is to get data of tectonic levels using a quantitative geomorphological approach carried out in the Batang Sinamar sub-watershed and the Batang Tampo sub-watershed. Some of the parameters used for this study include Drainage Density (Dd), Bifurcation Ratio (Rb), Hypsometric Integral (HI), Valley Floor Width and Height Ratio (Vf), Mountain Front Sinousity (Smf), and Asymmetry Factor (AF). And then the outcome of the parameters compared using IAT (Index of Active Tectonic) analysis. The results of the calculation are obtained with segment 1 entering class 3, namely moderate tectonics, and segments 2 and 3 entering class 2, namely high tectonics. The drainage pattern of the river at this research location is a pararellel drainage pattern which is controlled by geological structures such as folds. The results calculation of the IAT analysis is the landform of the morphology research location is controlled by moderate to high levels of tectonic activity and produces various denudational and erosional processes that cause soil movement and landslides.

Abstract

Krakatoa is the most active volcanic complex located in Lampung Province, Indonesia. Throughout human history, several devastating Krakatoa eruptions have shocked the world and turned it into a global attraction. Recognizing its scientific value, Krakatoa has been designated as a geoheritage site. This study refers to the Standard Scientific Value Assessment published by Center for Geological survey of Indonesia, which applies seven main parameters, including well-published scientific reviews, to assess the feasibility of geoheritage sites. In conclusion, the Krakatoa volcanic complex is a highly regarded geoheritage site, scoring 92.5/100. Its significance extends globally, offering insights into the evolution of volcanic islands and their unique geological features. Additionally, the historical records of global catastrophes and the potential for future eruptions warrant further investigation. As a geoheritage site, Krakatoa serves as a reminder of the possibility of subsequent devastating eruptions and its natural history, making it crucial for sustainably maintaining, preserving, and managing its potential for educational, conservation, and scientific purposes. Considering the natural history, the study recommend further consideration of several sustain steps, particularly for sites around the Krakatoa area. Regular and systematic scientific observations and records of natural conditions are significant for maintaining and enhancing Krakatoa as geoheritage.

Abstract

Hidrometalurgi dapat diartikan sebagai cara pengolahan logam dari batuan atau bijihnya dengan menggunakan pelarut berair (aqueous solution), atau secara detailnya hidrometalurgi adalah suatu proses dalam pekerjaan metalurgi dimana dilakukan pemakaian suatu zat kimia yang cair untuk dapat melarutkan suatu partikel tertentu. Salah satu tahapan yang penting dalam jalur proses hidrometalurgi adalah proses Leaching atau pelindian. Pada penelitian ini dilakukan proses pelindian bijih mangan yang diperoleh dari Desa Kumbewaha, Kecamatan Siotapina, Kabupaten Buton. Dimana kadar mangan (Mn) 60,89% dan kadar besi (Fe) 0,83%. Pada tahap pelindian ini diawali dengan melakukan preparasi bijih mangan dengan mereduksi ukuran hingga diperoleh 200 mesh. Pelindian yang dilakukan yaitu dengan menggunakan larutan asam sulfat (H2SO4), dengan variasi konsentrasi larutan 4%, 6%, 8%, 10%, persen solid pelindian 5%, 10%, 15%, 20%, temperatur pelindian 70ºC, 80ºC, 90ºC, 100ºC dan waktu pelindian selama 180 menit dengan molases 50g/l. Hasi penelitian menunjukan persentase perolehan Mn tertinggi yaitu 91,33% diperoleh pada konsentrasi asam 10%, persen solid 20%, temperatur 100ºC dan waktu pelindian 180 menit sedangkan persentase perolehan Fe tertinggi yaitu 80,01% diperoleh pada konsentrasi asam 10%, persen solid 20%, temperatur 100ºC dan waktu 180 menit

Abstract

One of the companies engaged in tin mining is PT Berkat Berjaya Sejahtera with reclamation planning from 2013 to 2022 with a planned land area of 10 Ha. However, the available area exceeds the planned area of 11.08 Ha. Based on these problems, the purpose of this research is to plan reclamation techniques and reclamation cost plans so that reclamation activities can run effectively and efficiently. The method used in this research is quantitative method. The data taken are soil pH and water pH data, topographic data (x, y, z coordinates). Data processing is carried out using a drone tool which is processed using surpac, minescape and surfer software. Based on the results of the research that has been carried out, it can be concluded that the reclamation technique plan is carried out by land stewardship by closing the void starting from elevation 2 to elevation 11 masl and leveling the land area to be reclaimed. The type of plant used in reclamation is oil palm the costs required for this reclamation are divided into 2, namely, Direct Costs and Indirect Costs. Direct costs required amount to Rp 1,326,572,000.00 and Indirect costs required amount to Rp 387,756,995.00. The total cost required for the reclamation of the 11.08 Ha land is IDR 1,714,328,995.

Abstract

Sulawesi or Celebes is located in the central part of the Indonesian archipelago which has interesting geological potential to be developed. One of this interesting area is known as Ambang volcano area. Ambang volcano is one of the active volcanoes in North Sulawesi. Administratively, the research area is located in Bongkudai Baru Village, Modayag sub-district, East Bolaang Mongondow district, mapped at coordinates N 0°45'58.89'' and E 124°24'13.04''. This study is aimed to analyze volcanic geomorphological units using satellite imagery and surface geological mapping. The results showed that the geological conditions of the study area consist of 4 lithologies i.e volcanic breccia, andesite, agglomerate and sandstone rocks. Based on the morphographic and morphogenetic analysis of the study area which refers to the Van Zuidam and Verstapen 1985 classification, the study area is divided into five landforms i.e fumarole and solfatara ambang volcanic, ambang volcanic cone, plains and fluvial slope feet of ambang volcano, denudational hill ambang volcanoes and lake units.
