Short Course that held on 26th March, 2016 at the class room at Institute Technology of Medan, Medaan, Indonesia that have a title “Eksploration Gold and Copper in Indonesia”, followed by 70 students Geology, Mining (ITM and ISTP), and lecturer from two department.The event that held by Executive Geology Institute Technology of Medan Student Chapter of American Association of Petroleum Geologists, HMTG”TOBA” ITM and also SM-IAGI ITM, this programme is held caused less knowledge about Eksploration Gold and Copper in Indonesia. In this event as speakers is Mr. Benny Alizar Amin Pulungan from PT. AGINCOURT RESOURCES GOLD MINE. This Event is at opens by Faculty Advisor of GITMSC OF AAPG is Ir. Lismawaty MT, with proudly, she is say thank’s for PT. Agincourt Resources Gold Mine on come In Institute Technology of Medan for delivery information in really and that bloom to Student Geology and mining so that increase know about mining.

Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved. Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation. Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries.

Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustacea copper is a constituent of the blood pigment hemocyanin, which is replaced by the iron-complexed hemoglobin in fish and other vertebrates. The main areas where copper is found in humans are liver, muscle and bone. The mining sector has made a very significant contribution to the Indonesian economy over the past several decades and will continue to do so for decades to come. According to a Fraser Institute survey, Indonesia is ranked amongst the top six countries in the world in terms of geological prospectivity. Indonesia is the seventh largest producer of both gold and coal in the world and the second-largest gold producer in Asia. Following the 10-year exodus of junior mining companies from Indonesia after the 1997 Asian economic crisis, Southern Arc’s management saw a unique window of opportunity. Acting quickly with a regionally-experienced team, Southern Arc became the first Canadian junior exploration company since 1997 to return to Indonesia and established a portfolio of exploration properties on Indonesia’s Lombok and Sumbawa islands. Indonesia hosts numerous large mineral deposits, including Newmont’s Batu Hijau copper-gold mine and Freeport’s giant Grasberg copper-gold mine. Grasberg produced 1.22 billion pounds of copper and1.79 million ounces of gold in 2010, making it the world’s largest gold mine and third largest copper mine. Newmont’s Batu Hijau mine produced 542 million pounds of copper and 737,000 ounces of gold in 2010, providing jobs for around 7,000 people who work directly for the mine or for contractors retained by Newmont to operate at the mine site. The Batu Hijau mine is a significant contributor to the local and national economy in Indonesia. Newmont has also reported plans to develop its Elang copper-gold porphyry deposit which is reported to contain 25 million ounces of gold and 16 billion pounds copper (Newmont press release February 2011). East Elang is located 63 km east of the Batu Hijau mine and adjoins Southern Arc’s East Elang property.  With decades of experience in Indonesian exploration and mining, Southern Arc’s management and directors provide an outstanding blend of experience and expertise to advance the company’s exploration and business objectives. Southern Arc’s management and directors bring a track record of achievements in international exploration, development, mining, engineering, company management, finance, acquisitions and administration.

This event can give a lot of opportunities for students to receive more knowledge and enhance their perception outside the classes about development mining and also training. We believe this program is important for those who want to be a geologist. It also give great opportunity to establish a good relationship among industry, AAPG, educational institution and students. Hopefully, this activity done well and will more knowledge to student about Short Course about Eksploration Gold and Copper in Indonesia”, and get motivation or inspiration to can join in mining industry.

Summary Guest Lecturer  Activity  of GITMSC OF AAPG by Mr. Dody Harysasmitha ( Guest Lecturer at ITM and Sedimentologist at GDA Consultant), Medan, Indonesia, March, 19th, 2016:

Guest Lecture held on 19th March, 2016 at Garuda Plaza Hotel, Medan, Indonesia that have a title “How to be A Sedimentologist , followed by 12 students Geology and include commitee of GITMSC OF AAPG.The event that held by Executive Geology Institute Technology of Medan Student Chapter of American Association of Petroleum Geologists, this programme is held caused less knowledge about How to be A Sedimentologist. In this event as speakers is Mr. Dody Harysasmitha as a guest lecturer in Istitute Technology of Medan and also a Sedimentologist at GDA Consultant.

Sedimentology encompasses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation (erosion and weathering), transport, deposition and diagenesis. Sedimentologists apply their understanding of modern processes to interpret geologic history through observations of sedimentary rocks and sedimentary structures. Sedimentary rocks cover up to 75% of the Earth’s surface, record much of the Earth’s history, and harbor the fossil record. Sedimentology is closely linked to stratigraphy, the study of the physical and temporal relationships between rock layers or strata. The premise that the processes affecting the earth today are the same as in the past is the basis for determining how sedimentary features in the rock record were formed. By comparing similar features today to features in the rock record – for example, by comparing modern sand dunes to dunes preserved in ancient aeolian sandstones – geologists reconstruct past environments.

Sedimentary rocks provide a multitude of products which modern and ancient society has come to utilise.

Art: marble, although a metamorphosed limestone, is an example of the use of sedimentary rocks in the pursuit of aesthetics and art

Architectural uses: stone derived from sedimentary rocks is used for dimension stone and in architecture, notably slate, a meta-shale, for roofing, sandstone for load-bearing buttresses

Ceramics and industrial materials: clay for pottery and ceramics including bricks; cement and lime derived from limestone.

Economic geology: sedimentary rocks host large deposits of SEDEX ore deposits of lead-zinc-silver, large deposits of copper, deposits of gold, tungsten, Uranium, and many other precious minerals, gemstones and industrial minerals including heavy mineral sands ore deposits

Energy: petroleum geology relies on the capacity of sedimentary rocks to generate deposits of petroleum oils. Coal and oil shale are found in sedimentary rocks. A large proportion of the world’s uranium energy resources are hosted within sedimentary successions.

Groundwater: sedimentary rocks contain a large proportion of the Earth’s groundwater aquifers. Our understanding of the extent of these aquifers and how much water can be withdrawn from them depends critically on our knowledge of the rocks that hold them (the reservoir).

The aim of sedimentology, studying sediments, is to derive information on the depositional conditions which acted to deposit the rock unit, and the relation of the individual rock units in a basin into a coherent understanding of the evolution of the sedimentary sequences and basins, and thus, the Earth’s geological history as a whole. The scientific basis of this is the principle of uniformitarianism, which states that the sediments within ancient sedimentary rocks were deposited in the same way as sediments which are being deposited at the Earth’s surface today. The principle of superposition is critical to the interpretation of sedimentary sequences, and in older metamorphic terrains or fold and thrust belts where sediments are often intensely folded or deformed, recognising younging indicators or graded bedding is critical to interpretation of the sedimentary section and often the deformation and metamorphic structure of the region. Folding in sediments is analysed with the principle of original horizontality, which states that sediments are deposited at their angle of repose which, for most types of sediment, is essentially horizontal. Thus, when the younging direction is known, the rocks can be “unfolded” and interpreted according to the contained sedimentary information. The principle of lateral continuity states that layers of sediment initially extend laterally in all directions unless obstructed by a physical object or topography. The principle of cross-cutting relationships states that whatever cuts across or intrudes into the layers of strata is younger than the layers of strata.

This event can give a lot of opportunities for students to receive more knowledge and enhance their perception outside the classes about development oil and gas company. We believe this program is important for those who want to be a geologist. It also give great opportunity to establish a good relationship among industry, AAPG, educational institution and students. Hopefully, this activity done well and will more knowledge to student about How to be A Sedimentologist”, and get motivation or inspiration to can join Oil and Gas Company after graduation.

A major application of petrophysics is in studying reservoirs for the hydrocarbon industry. Petrophysicists are employed to help reservoir engineers and geoscientists understand the rock properties of the reservoir, par- ticularly how the pores in the subsurface are interconnected, controlling the accumulation and migration of hydrocarbons.Some of the key properties are studied in petrophysics lithology, porosity, water saturation, permeability and density. A key aspect of petrophysics is measuring and evaluating Reviews These rock properties by acquiring well log measurements – in the which a string of measurement tools are inserted in the borehole, core measurements – in the which rock samples are retrieved from the subsurface, and seismic measurements. Reviews These studies are then combined with geological and geophysical studies and reservoir engineering to give a complete picture of the reservoir. While most petrophysicist work in the hydrocarbon industry, Also some work in the mining and water resource industries. The properties measured or computed fall into three broad categories: conventional petrophysical properties, mechanical rock properties, and ore quality. Petrophysical studies are used by petroleum engineering, geology, mineralogy, exploration Geophysics and other related studies and most petrophysicists are employed to compute what are commonly called conventional (or reservoir) petrophysical properties. These are:

Lithology: A description of the rock’s physical characteristics, such as grain size, composition and texture. By studying the lithology of local geological outcrops and core samples, geoscientists can use a combination of log measurements, such as natural gamma, neutron, density and resistivity, to determine the lithology down the well.

Porosity: \phi The percentage of a given volume of rock that is pore space and can therefore contain fluids. This is typically calculated using data from an instrument that measures the reaction of the rock to bombardment by neutrons or by gamma rays but can also be derived from sonic and NMR logging.

Water saturation: The fraction of the pore space occupied by water. This is typically calculated using data from an instrument that measures the resistivity of the rock and is known by the symbol S_w.

Permeability: The quantity of fluid (usually hydrocarbon) that can flow through a rock as a function of time and pressure, related to how interconnected the pores are. Formation testing is so far the only tool that can directly measure a rock formation’s permeability down a well In case of its absence, which is common in most cases, an estimate for permeability can be derived from empirical relationships with other measurements such as porosity, NMR and sonic logging.

Thickness of rock with enough permeability to deliver fluids to a well bore. This property is often called “Net reservoir rock.” In the oil and gas industry, another quantity “Net Pay” is computed which is the thickness of rock that can deliver hydrocarbons to the well bore at a profitable rate.

Reservoir models are built upon their measured and derived properties to estimate the amount of hydrocarbon present in the reservoir, the rate at which that hydrocarbon can be produced to the Earth’s surface through wellbores and the fluid flow in rocks. In the water resource industry, similar models are used to compute how much water can be produced to the surface over long periods of time, without depleting the aquifer.

This event can give a lot of opportunities for students to receive more knowledge and enhance their perception outside the classes about development oil and gas company and also training software in workshop event with interactive petrophysic/ IP Petrophysic software too in second day for this event. We believe this program is important for those who want to be a geologist. It also give great opportunity to establish a good relationship among industry, AAPG, educational institution and students. Hopefully, this activity done well and will more knowledge to student about Two days Short Course and Workshop about Carbonate Petrophysic and Software Application”, and get motivation or inspiration to can join Oil and Gas Company after graduation.

Summary Research Activity of GITMSC OF AAPG at BMKG Goverment Institution about Observation of a Solar Eclipse in the World, Medan, Indonesia, March 09th, 2016:

Research activity of GITMSC of AAPG on 09th March 2016 in BMKG Goverment Institution, Deli Sedang, North Sumatera, Indonesia that have a title “Observation of a Solar Eclipse in the World”, and this event followed by 10 participants from GITMSC OF AAPG include the commitee and 5 professionals BMKG researchers and also 30 guests from various institution and total is 45 Participants for this event .

Natural phenomenon a total solar eclipse (GMT) which will take place on 9 March 2016 will be seen in 12 cities in Indonesia, namely, Palembang, Belitung, Balikpapan, Luwuk, Sampit, Palu, Ternate, Bangka, Palangkaraya, Poso, and Halmahera. Although some cities are going to feel a total solar eclipse, but the rare natural phenomenon occurred was welcomed by a number of Indonesian society. Lodging in North Sumatera, the peak of the solar eclipse only occurs in 80 per cent and 06.30 to 09.00 am and its peak will last for 2-3 minutes and for this event from the results of observations made throughout much of North Sumatra will experience a total solar eclipse, and at the peak of the eclipse is only visible North Sumatra is 80 percent.

The safe way to observe the eclipse is when the moon covered the sun slowly and gradually into the dark sky conditions (partial solar eclipse) is recommended to use filters or special glasses to see the sun. How to see it also should not be too focused because at that time the sun is not all closed and some sunlight still emanates strong that it can damage the eye’s retina. As the sun covered in total and the sky became dark, a filter that protects the eyes can be removed. The beauty of a total solar eclipse can be seen directly by eye. It should be remembered, not too long staring at for the duration of a total solar eclipse is only 2 to 3 minutes. After that the sun will be parted and the sky brightened. As the sun began parted, the eyes must be used in order to filter the sunlight does not damage the retina.

Solar eclipse occurs when the moon positions located between the Earth and the Sun, thereby closing some or all of the sun’s light. Although the moon is smaller, the shadow of the Moon is able to protect sunlight entirely because of the moon within an average distance of 384 400 kilometers from Earth closer than Sun has an average distance of 149 680.000 kilometers.

Solar eclipse can be divided into four types:

Gerhana Solar total eclipse occurs when the peak time, the disk of the Sun is closed completely by a disk of the Moon. At that time, the Moon disc as large or larger than the disk of the sun. The sun disc size and the disc moon itself varies depending on each distance Earth-Moon and the Earth-Sun.

Gerhana Partial sun, occur when the disc moon (when the peak eclipse) only cover part of the Sun disc. In this eclipse, there is always a part of the Sun disc that is not covered by a disk of the Moon.

Gerhana Sun ring, occur when the disc moon (when the peak eclipse) only cover part of the Sun disc. This type of eclipse occurs when the size of the disk of the Moon is smaller than the Sun disc. So that when the disc Moon is in front of the disc of the Sun. Gerhana Hybrid solar, shifts between total eclipse and ring. At a certain point on the earth’s surface, this eclipse appears as a total eclipse, whereas at other points appear as a ring eclipse. Hybrid eclipses are relatively rare.

Look directly into the solar photosphere (the ring section brighter than the Sun) may be dangerous, because it resulted in permanent damage to the eye’s retina due to high radiation invisible emitted from the photosphere. The damage caused can result in blindness. Observe the solar eclipse requires special eye protection or using viewed indirectly. The use of goggles to watch the eclipse is not safe because it does not filter out infrared radiation that can damage the eye’s retina. Due to the rapid circulation of the Earth around the sun, the solar eclipse could not have lasted more than 7 minutes and 58 seconds, so that the observation should be done as soon as possible.

There are so many activities that can be seen when the Total Lunar Eclipse started many people watch with the naked eye by taking the help of a telescope for astrophotography etc. Lunar Eclipse interesting to watch and learn, semisalnya to check the accuracy of calculation of the coordinates of celestial bodies. As well as astronomy we can know that the lunar eclipse will affect gravity Sun and the Moon to the Earth that causes the maximum ocean tides. Moreover, the phenomenon of GBT also be used as a platform for students to try to make observations as well as shooting and analysis pascapengamatan. Among the activities that students can do is observe the contact times that happened.

This event can give a lot of opportunities for all people to receive more knowledge and enhance their perception outside the classes about development of earth science, including a solar eclipse. We believe this program is important for those who want to be a geologist also. It also give great opportunity to establish a good relationship among industry, AAPG, educational institution and students. Hopefully, this activity done well and will more knowledge to student about Observation of a Solar Eclipse in the World”.
