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

Field surveys in the Sulili Region show geothermal characteristics in the form of manifestations, namely hot water springs. This study aims to determine the type of geothermal fluid in the study area based on the Na-K-Mg geothermometer method and then classify it based on trilinear and ternary diagrams. The results showed that the types of hot springs from the three hot springs in the study area were included in the chloride type with a percentage between 96.209% -96.651% which was plotted on the trilinear diagram. Based on the ternary diagram plotting, the geothermal fluid in the study area belongs to the immature water group. Based on the results of the study it can be concluded that the type of hot water springs in the study area is chloride with one of the hot springs included in the immature water group, namely EPU-1 hot water spring station, while two hot water spring stations, such as EPU-2 and EPU-3 stations cannot plotted due to the high levels of Mg at that station.

Abstract

Geology is an important aspect in the development of tourism in an area. One of the attractions in a natural tourism location is certainly highly controlled by the geological setting in the area. The purpose of this research is to assess tourism values of geological features in the Bongo and surrounding areas as a basis for developing geotourism on the southern coast of Gorontalo. The research location is at coordinates N 00029’42” - N 00029’51” and E 12301’26” - E 12303’32”. The method used in this study is a surface geological survey, which includes field data collection in the form of lithology, geological structure and geomorphology. The standard used for assessing tourism values is the technical guide for assessing geological heritage resources by the Geological Survey Center. The results showed that the lithology unit of the study area consists of granite, volcanic breccia and reef limestone. The geological structure in the research area is shear fracture with main stress that relatively directed to northwest-southeast. The geomorphic unit of the study area consisted of two units, namely volcanic hills, and marine units. The results of the assessment of tourism values on geological features explain that the Bongo and surrounding areas are included in the medium category. Improvements are needed on low value criteria, namely vulnerability, relationships with other values, and economic level.

Abstract

Laboratory analysis has proven the Talang Akar Formation as a source rock that is relatively rich in organic content, but the availability of laboratory data is very limited to determine the quantity of organic material in a regional basin area, which is the main objective in this research. Therefore, a simple proven and accurate method is needed to model the TOC (organic carbon content) throughout the borehole is needed. TOC log modeling was performed using the Passey method, multilinear regression and neural network. Based on the modeling results, the multilinear regression method got better results to be applied to the Talang Akar Formation.

Abstract

The research area is a gold mine operating in North Sulawesi. The aim of the study was to analyze and calculate hydrological parameters, namely: hydraulic conductivity, infiltration rate, and permeability to find out how strong the soil cover is at one level of waste disposal. The method used is the Measurement of hydraulic conductivity, infiltration rate, and permeability in the field, analysis, and calculation of hydraulic conductivity, infiltration rate, and permeability based on field data. In the designated regions of the waste dump, specifically areas 1a, b, and c, we observed certain hydrological patterns that are worth noting. Firstly, the hydraulic conductivity in these areas, which is a crucial determinant of the rate at which water can move through the soil, consistently showcased low average values. This is further supported by the similarly slow infiltration rate identified in the same zones. The ability of the soil to transmit water, i.e., its permeability, also followed this trend, with values leaning towards the lower end of the scale, indicating very slow permeability. One major contributory factor to these patterns appears to be the soil's composition. Predominantly made up of sandy loam, the soil in these areas exhibits high water retention capabilities. Sandy loam, by its nature, binds and retains water effectively, which could potentially explain the observed hydrological behaviors in waste dump areas 1a, b, and c.

Abstract

Formasi Kampungbaru di wilayah Balikpapan, Kalimantan Timur merupakan satuan batuan sedimen yang didominasi oleh batupasir dan memiliki potensi geologi yang signifikan. Studi terhadap batupasir dari formasi ini penting untuk memahami asal usul material penyusunnya serta dinamika geologi yang berperan dalam proses sedimentasinya melalui pendekatan geokimia yang dapat mengidentifikasi komposisi kimia dan lingkungan tektonik asal dari sedimen. Sebelas sampel batupasir diambil dari lokasi terpilih di lapangan dan dianalisis dengan menggunakan portable XRF analyzer untuk menentukan kandungan unsur utamanya. Hasil analisis menunjukkan bahwa batupasir Formasi Kampungbaru didominasi oleh kandungan SiO₂ yang tinggi dan Al₂O₃ yang sedang dengan rasio Al₂O₃/SiO₂ yang rendah hingga menengah serta kandungan Fe₂O₃ + MgO yang relatif tinggi yang mengindikasikan bahwa material penyusun batupasir kemungkinan besar berasal dari batuan vulkanik atau beku mafik yang terbentuk pada lingkungan busur samudra atau margin kontinental aktif. Keberadaan wacke dan arkose yang dominan menandakan batupasir ini terendapkan dalam lingkungan dengan energi yang bervariasi, mulai dari laut dalam hingga area dekat sumber granitik. Selaras dengan sejarah geologi Kalimantan bagian timur yang pernah mengalami aktivitas magmatik subduksi pada zaman Tersier. Proses ini kemudian menghasilkan sedimen yang terbawa ke arah timur melalui sistem sungai dan diendapkan dalam lingkungan delta dan laut dangkal membentuk Formasi Kampungbaru. Dengan demikian, batupasir pada Formasi Kampungbaru mencerminkan provenance campuran antara continental block dan recycled orogen.
