Abstract

The tectonic history of Sulawesi is closely related to the activities of the three major world plates that surround it. This results in the complexity of geological conditions on the island of Sulawesi, including the diversity of rock types. One of the most common types of rock is igneous granite, which is widespread in the Sibayu area, Donggala Regency, Central Sulawesi Province. This study aims to determine the characteristics and petrogenesis of igneous granite using megascopic and microscopic or petrographic observation methods. The results showed that the rock has a megascopic appearance in the form of a grayish-white fresh color and a brownish weathered color, a holocrystalline texture, a massive structure, and a mineral composition consisting of orthoclase, amphibole, and quartz. Its microscopic appearance shows a brownish-transparent color on parallel nikol, on brown cross-linked nikol, light gray to dark gray, mineral size 0.15-0.05 mm, the average mineral composition is orthoclase (41.25% ), quartz (43.75%), biotite (11.25%) and plagioclase (3.75%). Based on these data, it can be concluded that the rocks are Late Miocene to Late Pliocene, which proves that the Palu-Koro fault was still active during the Late Miocene to Late Pliocene. The presence of biotite in granitic rocks characterizes S-Type granite which is formed deep below the earth's surface which is characterized by euhedral-subhedral forms.

Abstract

Buton asphalt is a natural asphalt on Buton Island, Southeast Sulawesi. To meet the target of Buton asphalt production, it is necessary to develop an area in the Lawele area as one of the asphalt producing areas on Buton Island. The purpose of this study was to determine the distribution of Buton asphalt and the form of asphalt deposits in the Lawele area, Buton Regency. The research methodology is divided into literature study, data collection, data processing, analysis and discussion and conclusions. The data used in this research is drill data which includes coordinates, elevation, lithology type, thickness, and depth of drill point. Data processing and analysis in this study was carried out through lithological correlation using RockWorks 17 software. Lithological correlation was carried out to determine the continuity of the asphalt layer from one drill point to another drill point. Based on the results of the analysis on the cross-sectional correlation that has been carried out, it can be concluded that the direction of distribution of asphalt deposits in the research area in line 1 and line 3 is from west to east with a tabular morphology of asphalt deposits, while on line 2 is single deposit and asphalt seepage is found.

Abstract

Area studi terletak di Sijunjung, dan secara tektonik berada di cekungan Ombilin yang dianggap sebagai intramountain basin atau cekungan sedimen yang berada di jalur pegunungan Bukit Barisan. Pemetaan geologi telah dilakukan sebelumnya, dan studi ini melakukan evaluasi struktur dengan mengintegrasikan data lapangan dan hasil interpretasi lineament melalui citra Digital Elevation Model (DEM) dengan menggunakan aplikasi ArcGIS dan perangkat lunak PCI-Geomatica. Hasil analisis citra memperlihatkan arah pola kelurusan umum NW-SE, dan orientasi ini terlihat konsisten dengan arah umum struktur geologi yang berkembang di daerah penelitian, terutama sesar Padangdoto, sesar Aie Angek, dan sesar Takung. Pola lineament dan sebaran sesar yang keduanya mengarah NW-SE dapat diinterpretasikan bahwa struktur geologi di daerah penelitian kemungkinan dipengaruhi oleh gaya transtensional yang ditimbulkan oleh pergerakan sesar aktif di sepanjang pegunungan Bukit Barisan.

Abstract

Sumatera memiliki orientasi fisiografi berarah Baratlaut dan terletak dibagian Baratdaya Lempeng Hindia-Australia dan di Selatan Lempeng Eurasia. Pulau Sumatera terbentuk akibat pertemuan antara dua lempeng, yaitu Lempeng Indo-Australia yang menunjam kebawah Lempeng Eurasia. Desa Muaro, Kabupaten Sijunjung, Sumatera Barat berada pada Cekungan Ombilin yang keterbentukannya dipengaruhi oleh sesar mendatar Sumatera dan diinterpretasikan sebagai intramontane basin yang terbentuk akibat adanya pergerakan tensional dari Sistem Sesar Sumatera. Metode yang dilakukan dalam penelitian berupa pemetaan geologi yang berfokus pada struktur geologi dan analisis kelurusan berdasarkan Digital Elevation Model (DEM) terhadap observasi lapangan. Analisis kelurusan dilakukan menggunakan data citra DEMNas (Digital Elevation Model) yang kemudian di ekstraksi pada aplikasi ArcGIS 10.3 dan PCI-Geomatica. Pola kelurusan yang di dapatkan digunakan untuk menggambarkan korelasi antara arah kelurusan dengan struktur geologi pada daerah penelitian. Tujuan penelitian dilakukan yaitu untuk mengkorelasikan hasil analisis hubungan antara pola kelurusan dengan hasil observasi lapangan. Hasil analisis DEM menunjukan pada daerah penelitian memiliki pola kelurusan relatif berarah baratlaut-tenggara yang kemudian ditunjukkan dengan keterdapatan struktur geologi berupa Antiklin Kabun, Sinklin Silokek, Antiklin Kabun, dan Sesar Kabun. Hasil analisis menunjukan bahwa hubungan antara pola kelurusan dengan keterdapatan struktur geologi dilapangan relatif sama. Hal ini juga diakibatkan oleh adanya aktivitas tektonik yang membentuk gaya kompresi dengan arah relatif utara-selatan.

Abstract

Zeolit adalah mineral aluminosilikat terhidrat yang memiliki struktur berongga sehingga dapat digunakan sebagai bahan penyerap. Sifat absorben zeolit ini berguna dalam menyerap zat-zat beracun seperti amoniak dan logam berat, sehingga dapat digunakan sebagai imbuhan pakan ternak, tambak, penjernihan air limbah dan penjernihan minyak kelapa sawit. Akan tetapi, umumnya zeolit yang digunakan merupakan jenis zeolit alam yang memiliki rasio Si/Al rendah dan kandungan mineral pengotor yang relatif tinggi sehingga dapat mengurangi kemampuan absorpsi zeolit. Salah satu metode aktivasi zeolit adalah dealuminasi secara kimia yaitu proses penurunan kandungan Al pada struktur kristal zeolit untuk meningkatkan rasio Si/Al. Tujuan penelitian ini adalah untuk mengetahui komposisi mineralogi dan kimia zeolit. Selanjutnya percobaan dealuminasi zeolit dilakukan dengan menggunakan pelarut asam sulfat dengan variabel konsentrasi dan suhu. Hasil analisis menunjukkan zeolit mengandung mineral feldspar, klinoptilolit, mordenit, dan kuarsa, Komposisi kimia didominasi oleh SiO2 dan Al2O3. Hasil percobaan menunjukkan rasio Si/Al mengalami kenaikan dari 1,09 menjadi 1,29 yang diperoleh pada konsentrasi H2SO4 1,5 M dan suhu 100.

Abstract

One of the major tectonic manifestation in Sulawesi Island is the Palu-Koro fault which extends north-northwest to south-eastwards in the centre of the island. The presence of the Palu-Koro Fault has responsible for the series of natural disasters occurred in Central part of Sulawesi and its surrounding which include earthquake, tsunami, liquefaction and subsidence. The need for further tectonic studies and geological structure mapping surrounding the fault is very important for disaster risk reduction strategy including mitigation effort to reduce casualties affected by future disasters. The study was conducted along Palu-Koro Fault Zone in Donggala Regency, Central Sulawesi. This study aims to assess the disaster risk including vulnerability, threat and capacity that generated by tectonically-controlled process along Palu-Koro Fault in Donggala Regency due to 2018 earthquake. The methodology used includes disaster risk reduction assessment approach, field geological structure observation, satellite imagery analysis using high-resolution satellite image from the Center for Remote Sensing Technology and LAPAN (National Institute of Aeronautics and Space), Pleiades satellite imagery with a resolution of 0.5 meters and SPOT 7 satellite imagery with a resolution of 1.5 meters. The result shows that the study area is prone to tsunami, earthquake, liquefaction and subsidence processes. Tsunami, earthquake and subsidence are grouped into high-risk disaster whereas liquefaction is considered as having moderate-risk level. The results of the assessment are expected to be used as a solid basis for planning disaster risk reduction efforts in the future.

Abstract

The prospect of Gunung Lipan is located in Rorowatu District, Bombana Regency, Southeast Sulawesi Province.  Physiographically it is situated in the Rumbia mountains, which is occupied by the metamorphic rocks of Pompageo complex. The Gunung Lipan is a prospect which has potential to produce gold mineralization in the Rumbia Mountains. However, a detailed research has never been carried out, in which the latest research is still on regional scale. Therefore, this study aims to understand more details about the geological conditions, alteration types and mineralization characteristics of the prospect and its surroundings. The research methods include geological mapping, petrographic analysis to determine type of hostrock, ore microscopy analysis to determine sulfide minerals in rocks/veins, and ore geochemistry to determine metal content in rocks and veins. Gold mineralization in the Gunung Lipan is hosted by mica schist, and controlled by sinistral shear fault in form of shear zone. The fault movement in the field is indicated by the presence of a milonite structure in the rock and the texture of mica fish on microscopic observations. The hydrothermal alteration appears at the study area is a typical type of alteration found in orogenic gold deposits such as silicification, carbonatization, and carbonization, argillic and propylitic. The sulfide minerals of orogenic type of gold deposit occurred in this study consist of stibnite, sinnabar, tripuhyite, pyrite, arsenopyrite, and hematite. Sulphide minerals are present in rocks and veins in disseminated form. Based on the results of geochemical analysis of gold content ranging from 0.005 ppm to 1.25 ppm, high grade gold was found in quartz veins that cross-cut foliation and veins with brecciated texture. Correlation of metallic elements using multivariate statistical methods shows that gold is positively correlated with As, Sb, and Hg, negatively correlated with Ag, and base metal elements (Pb, Zn, and Cu) are not abundant and are depleted when there is an increase in degree of metamorphism, which obviously implies a typical characteristics of orogenic gold deposit.

Abstract

Research has been carried out regarding the source rock of iron ore deposits. This area became the object of research because of the discovery of iron ore deposits and several other metals. In this research, the focus of the study is the source rock that carries Fe metal. The results of the initial study indicate that the basalt is thought to have carried the metal intruding the wall rock causing a reaction to occur. The analysis in this paper consists of field research, sampling, preparation, and analysis of petrography and XRD. Based on petrographic observations, basalt is composed of the main minerals in the form of pyroxene minerals, plagioclase, and base mass with a distinctive texture in the form of a porphyry texture where pyroxene and plagioclase minerals as phenocrysts are embedded in the base mass and opaque minerals. The secondary minerals found were epidote, actinolite, hornblende, anatase, staurolite, carbonate minerals, chlorite, sericite, magnesite, clay minerals, and quartz. The ore minerals are magnetite, goethite, chamosite, and pyrope.

Abstract

One of the important aspects in urban solid waste management is the problem of leachate which if it is not managed properly will cause a serious threat to the environment, because leachate production will enter underground water streams and also surface water. Leachate is a liquid that flows or 'dissolves' from landfills, with a composition that varies depending on the age of the landfill and the type of waste contained in it. This leachate usually contains dissolved bacteria or and insoluble bacteria. The study site is composed of clastic sedimentary rocks in the form of sandstones and conglomerates, which are included in the Miocene Pliocene Sand (Tmps) tertiary rock formations and the Miocene Conglomerate Tertiary (Tmc). The results of previous studies found that the area where the waste landfill is located on coarse to fine-grained rocks, which is very likely that the flow of leachate contained in the waste landfill location will affect the quality of the water system around the waste landfill location. From the results of this study, it can be known the direction of leachate flow by the geoelectric method and the extent of its effect on the groundwater system in the area around the landfill
