Abstract

School partners indicated that there were several problems, namely that there were still students who did not understand how to interpret resistivity geoelectrical data. This is due to the limited facilities and infrastructure as well as teaching staff in supporting the learning process in schools. The purpose of this PkM is to prepare students' abilities as early as possible so that they can understand how to interpret resistivity geoelectrical data before entering the world of work in geology and mining. Another thing is that school partners can more easily and effectively teach the interpretation of resistivity data using the geoelectric method in the teaching and learning process in schools.. The method used in achieving the objectives is a questionnaire (pretest and posttest) with descriptive statistical analysis, lectures (presentations) and discussions as well as field practice. The results of the analysis showed an increase in students' ability in the acquisition of geoelectric resistivity data after attending the training. Prior to participating in the training, 70% of students had the ability to acquire geoelectric resistivity data in the Poor category. However, after participating in the training, the students' abilities increased to Excellent (55%).

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

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

Water is a source of necessity for humans. Water quality is very important to be considered as the source of clean water. Some people in Maros Baru District use ground wells as the source of water needs. Therefore it is important to know the physical quality and pH level of shallow wells and to know the worthiness of shallow wells in Maros Baru District with reference to Permenkes No.492/ 2010. This study examined the feasibility of water based on the physical quality and the pH level of water taken from shallow wells. The research was carried out directly in field with 14 sampling points scattered in the north, east, south, west and at the center of field. The method in observing pH value is by litmus paper and observation on the physical condition of water, well depth, well diameter and surface level of water. The result shows there were 2 locations with saltwater taste, as the location is near from the sea and rivers, while turbidity of the water influenced by condition of surround environment that was not properly maintained. From data processing, it can be concluded that as many as 5 of the 14 sampling points did not meet the eligibility standards of Permenkes No.492/2010 to be used as a source of clean water intended for drinking water.

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.
