Abstract

Coal is a unique sedimentary rock, both in the process of formation and rock characteristics which are strongly influenced by the conditions of the depositional environment. Different depositional environments, the characteristics of the coal are different. The research method used in this research in the field is in the form of direct sampling in the field using the channel sampling ply by ply method, namely sampling by making channels on coal outcrops and taking samples that represent the lower, middle and upper layers of the coal seam to determine the average characteristics. The sample is then prepared to get a certain size and can be representative of the field sample. The prepared samples were then subjected to a proximate test to determine the moisture content, ash content, volatile matter and fixed carbon. Laboratory tests are carried out in the Lab. Analysis and Processing Hasanuddin University Makassar. The results of the proximate analysis  carried out show the coal characteristics of the Walanae Formation in the Kaloling Region which has a moisture content value that decreases from bottom to top with an average of 7.49%; coal ash content increased from bottom to top with an average value of 47.63% ash content; the value of volatile matter decreased from bottom to top with an average of 26.56% of volatile matter; and the value of fixed carbon which increases with increasing depth with an average value of 18.29%.

Abstract

Potensi endapan bijih besi di Indonesia dijumpai di Kalimantan Selatan, Jawa Timur, Sulawesi Tengah, Sulawesi Selatan, Sulawesi Barat, dan Sumatera barat. Di Sulawesi Selatan, endapan sumberdaya bijih besi yang melimpah terdapat di Kabupaten Bone, Sulawesi Selatan tepatnya di Daerah Pakke, Kecamatan Bontocani. Sifat geokimia atau persentase unsur dan senyawa dari endapan bijih besi tersebut dapat digunakan sebagai data awal untuk menentukan apakah bijih besi tersebut layak untuk dieksploitasi atau dilakukan penambangan serta menjadi acuan proses ekstrasi dari bijih besi yang ada pada daerah penelitian. Penelitian ini bertujuan untuk mengetahui persentase kehadiran senyawa oksida dan persentase kehadiran unsur Fe, Mn, dan unsur logam dasar. Metodologi penelitian dilakukan dengan pengambilan data di lapangan dan analisa laboratorium yaitu melalui pengamatan secara langsung endapan bijih besi yang tersingkap di permukaan dan pengambilan sampel bijih dengan metode chip sampling dan rock sampling. Analisa laboratorium menggunakan metode XRF untuk mengetahui persentase senyawa utama (major element) dan metode ICP-OES untuk mengetahui kadar unsur Fe, Mn dan Unsur logam dasar (Cu, Pb dan Zn). Hasil penelitian menunjukan kehadiran Fe2O3 pada semua sampel dengan persentase 43,18% - 50,40%. Hal ini sesuai dengan dijumpainya mineral-mineral pembawa bijih besi (primer) yaitu hematit dan magnetit. Persentase kehadiran unsur Fe sangat tinggi dan berpotensi untuk dieksplorasi lebih lanjut. Unsur logam dasar lokasi penelitian sangat tinggi sehingga dapat dipastikan bahwa endapan bijih besi pada daerah penelitian adalah tipe calcic skran.

Abstract

To ensure the quality of education in vocational schools (Sekolah Menengah Kejuruan or SMK), the government intervenes through the Skills Competency Test (Uji Kompetensi Keahlian or UKK). During the UKK process for SMK Budi Bangsa students in March 2018, it was found that the participants generally had not yet mastered the material to be tested, specifically the use of topographic mapping equipment. This is likely due to the insufficient availability of adequate facilities and infrastructure at SMK Budi Bangsa. Therefore, training on the use of topographic mapping equipment is necessary to better prepare SMK Budi Bangsa students for a similar exam the following year. The topographic mapping training, using auto level and theodolite tools, aims to enhance students' knowledge and skills in accordance with the equipment usage guidelines and refer to the Code 1556 Vocational Practice Exam Assessment Sheet. The topographic mapping training was conducted at SMK Budi Bangsa from January 29 to February 4, 2019. The method used involved theoretical presentations on topographic mapping in general and the specific use of auto level and theodolite tools, as well as practical exercises on the usage of these tools, measurement and data processing, and the creation of topographic maps. The training activities were attended by 27 students, consisting of 14 students from class X, 3 students from class XI, and 10 students from class XII. From only 7.4% of the participants who initially possessed the knowledge and skills according to the first two stages of the reference before the training, they achieved improvement, with all participants acquiring the knowledge and skills according to all stages of the planned reference.

Abstract

One of the prospects for a wealth of geological resources that can be utilized for the benefit of mankind is manganese metal mineral resources. In Anabanua Village, especially at the research location, there is an indication of manganese mineralization that the type of rock carrying the mineralization is not yet known. The purpose of this study was to determine the chemical elements of metallic minerals, mineralogy, and types of mineralization-carrying rocks, as many as three samples in the form of chunks, which were analyzed using megascopic analysis methods identifying the texture and structure of carrier rocks, XRD (X-Ray Diffraction) analysis minerals, and XRF (X-Ray Fluorescence). The characteristics of manganese mineralization carrier rocks consist of metallic elements Mn (0.046%-20.455%), Fe (1.555%-3.673%), and nonmetallic elements SiO2 (11.403%-48.165%), K2O (0.398%-4.177%). Mineralogy of manganese mineralization carrier rocks are roeblingite (Pb2Ca6Mn2+(Si3O9)2(SO4)2(OH)2·4H2O), rhodonite (CaMn3Mn[Si5O15]), diopside (CaMgSi2O6), calcite (CaCO3), kieserite (Al, Ga)2(GeO4)(OH)2), zeolite (Mn2O.Al2O3.xSiO .yH2O), and palygorskite ((Mg, Al)2 Si4O 10(OH)·4H2O). Manganese mineralization host rocks are determined by referring to the SiO2 (%weight) and K2O(%weight) diagrams to produce basalt igneous rock types.

Abstract

Indonesia has the potential as an area containing large reserves of gold and sulfide minerals. One of the areas with the potential to produce gold is Bolaang Mongondow Regency, North Sulawesi Province. This study aims to identify the characteristics of epithermal deposition mineralization, including texture and the presence of mineralization, to determine its paragenesis. The analysis methods used are petrography, mineralogy, and X-ray Diffraction (XRD). As many as six samples in the test well are described megascopically and polarization microscopically, which have been ground into clay-sized fractions and analyzed using the X-ray Diffraction (XRD) method to detect clay minerals and other altered mineral associations. The quartz texture present at the research location based on megascopic observations is generally dominated by saccharoidal, vuggy, mold, banded, and chalcedonic textures. The identified minerals are generally dominated by base metal minerals, with paragenesis in sequence being pyrite, chalcopyrite, galena, hematite, ilmenite, and geothite. Alterations in the research area are in the form of Argillic, Silicic, Silica-Carbonate, and propylitic zones. The study's results concluded that the type of mineralization in Bolaang Mongondow Regency, North Sulawesi, is of the low-sulfidation epithermal type.
