Abstract

The regional tectonic conditions of the KSK Contract of Work are located in the mid-Tertiary magmatic arc (Carlile and Mitchell, 1994) which host a number of epithermal gold deposits (eg, Kelian, Indon, Muro) and significant prospects such as Muyup, Masupa Ria, Gunung Mas and Mirah. Copper-gold mineralization in the KSK Contract of Work is associated with a number of intrusions that have occupied the shallow-scale crust at the Mesozoic metamorphic intercellular junction to the south and continuously into the Lower Tertiary sediment toward the water. This intrusion is interpreted to be part of the Oligocene arc of Central Kalimantan (in Carlile and Mitchell 1994) Volcanic rocks and associated volcanoes are older than intrusions, possibly aged Cretaceous and exposed together with all three contacts (Carlile and Mitchell, 1994) some researchers contribute details about the geological and mineralogical background, and some papers for that are published for the Beruang Kanan region and beyond but no one can confirm the genesis type of the Beruang Kanan region The mineralization of the Beruang Kanan area is generally composed by high yields of epithermal sulphide mineralization. with Cu-Au mineralization This high epithermal sulphide deposition coats the upper part of the Cu-Au porphyry precipitate associated with mineralization processes that are generally controlled by the structure

Abstract

The Sunda Strait is one of the zones of the Eurasian plate encounters with fairly active Indian plates. This can be seen based on volcanic activity that occurred in the region of Mount Krakatau. But there are unique things that are important to learn is tectonic movement with geological forces that work to produce cracks in rocks, the formation of volcanoes and cracks that occur produce mineralized zones, especially in the Formation of Honje and Formation Cipacar and more widely known as Bayah Dome. The presence of mineralization of the Honje Formation and Cipacar Formation is particularly located in the District of Cimanggu, Mangku Alam Village, the existence of gold mining activities proves that the mineralization of the region has the potential of economy. The presence of mineralization will not be separated from the presence of rock fractures in the two formations that have different geological age of the Late Miocene and Plistocene. Both formations are hindered by the presence of unconformity fields. This study aims to prove the extent of tectonic activity occurring in the Honje Formation with the final Miocene age forwarded to the Cipacar Formation even though obstructed by the field of nonconformity with the results of field data processing based on the value of RMR and RQD value. Both parameters are also studied to determine the extent to which the RQD value determines the magnitude of the grade value of Gold (Au). The distribution of RMR value and rock RQD value is taken from 2 different rock units, ie, andesite rock units in Honje Formation and tuff rock units in Cipacar Formation, based on the data distribution around 125 RMR observation points and 117 RQD observation points in the field are processed by using method test the average difference of the two parameters from 2 different rock units. In addition, the RQD value was correlated to the high level of gold content using correlation regression test of 78 data content and RQD value. Results of processing and discussion of data indicate that between the value of RMR in andesit unit and tuff unit there is no difference in value means H0 accepted by tcount = 0.556 <ttable = 1.995, as well as the difference test average RQD value where the results show that there is no difference between the average value of RQD andesite rock units in Honje Formation and tuff rock units in Cipacar Formation with tcount = 1.714 <ttable = 1.995, based on the results of data processing it can be explained that the tectonic activity in Honje Formation with the final Miocene age is forwarded to Cipacar Formation even if obstructed the field of dissonance means that tectonic activity of the region is inferred as neotectonic activity of West Java. In addition, one more thing that can be concluded that the relationship of RQD with Gold content (Au) based on statistical test the greater the value of RQD then the value of gold content (Au) the greater the test results regression correlation value PValue (Significance) = 0.013 with the equation y = -0.715x + 75.882 value R2 42.39%. Because Significance value> 0.05 then H0 DENIED, so H1 accepted, where the higher the value of the Big Au content then the RQD Value the greater.

Abstract

The mechanical properties of Clay Shale are very unique. When it is dry, it shrinks and hardens, butwhen it absorbs water, it swells and to some extent loses its shear strength so that the drop-instrength can occur suddenly even with its own weight. Due to the nature of the swell-shrink that arestrongly influenced by climate and weather, clay shale durability may decrease over time when indirect contact with air and water. Research on clay shale was done in Sentul City, Bogor - West Java,Indonesia on Jatiluhur formation, using dynamic slaking (slake durability test) and slaking static test.Dynamic slacking test is done in three times i.e. after sampling, after 3 months and after 9 months.Slake durability test results from 3 different drilling points, shows that within 9 months, has not seenthe decreasing effect of durability. With a low Plasticity index, the durability research in Sentul City isin medium durability to medium-high durability classification.

Abstract

The simplest way to interpret polarimetric imagery for land cover classification is to use visualinterpretation methods. The existence of interpretations key as a tool for visual interpretation becomesimportant when different interpreters can produce different results. The quality of the results of theinterpretation of land cover is then determined by the quality of the interpretation tool, in this case, thekey to the interpretation of land cover. The purpose of this study was to make the key to land coverclass interpretation in the Full Polarimetric ALOS PALSAR image, then the interpretation key wasused for reference in making land cover maps and measuring the accuracy of the results of the visualinterpretation. The image used in this study consisted of HH, VV, HV and VH bands. The location ofthe study was in parts of Sleman District. The analysis is done visually by on-screen digitizing onALOS Palsar composite HH + VV HV + VH HH-HV image, which is then interpreted key. The truetest is done by means of the overall accuracy test and Kappa. Visually, ALOS PALSAR imagery isable to distinguish 12 land cover classes in the research area, namely built land, rice fields, mixedgardens, moorlands, salak garden, grass, forest, shrubs, open land, airports, water bodies and lavawith 83% Overall accuracy, and 78% Kappa accuracy.

Abstract

Mining activities often cause land damage. Land damage can be monitored from time to time, so it canbe controlled and solved. This research was conducted in Semin, Gunungkidul Regency, SpecialRegion of Yogyakarta, from November 2017 until March 2018. Semin area consist of many miningactivities and also directly adjacent with Central Java Province in the east and north. Therefore, thestudy of land damage caused by mining activities in this area is very important. The purpose of thisresearch is to know and study the condition of land damage caused by current mining activities. Themethod used in this research is weighting method by using Analytical Hierarchy Process (AHP) tosome parameters which mostly refers to the Decision of Governor of DIY Number 63 year 2003 asobserved parameter, that is 1) The character of rock compilation of excavation, 2) rock fracturing level3) Utilization and management of top soil, 4) Depth of excavation / height of wall, 5) Limit of slope ofexcavation, 6) Reclamation time, 7) Amount of erosion, 8) River flow / sedimentation. The level ofdamage is divided into three, based on the value, that is 1) Good (1.00-1.66), 2) Medium (1.67 - 2.33),and 3) Damaged (2.34 - 3.00). Total mine sites observed were 81 mine sites. There are 10 mine sitesincluded in the Good category, 68 mine sites belonging to the Medium category, and 3 mine sites inthe Damaged category.
