Abstract

The area of Mount Tampomas which is located in Buahdua District, Conggeang District, and Tanjungkerta District, Sumedang Regency, West Java was chosen as the research area because it is predicted to have geothermal potential with the presence of geothermal manifestations such as hot springs. The presence of manifestations relates to permeable zones controlled by geological structures. The lineament of the ridge and valley was observed and analyzed using ASTER GDEM remote sensing imagery and Indonesia Earth Form map (RBI), scale 1:25.000. The purpose of the study is to find out the relationship between permeability and the presence of geothermal manifestations in the research area. Research method by conducting remote sensing and fault fracture Density (FFD) analysis using 3D micromine software modeling. Results of remote sensing analysis with irradiation angle of 0°, 45°, 90°, 135° and altitude 45° shows the main pattern of the ridge - valley lineament interpreted as a fault in the research area have a relatively northwest-southeast and northeast-southwest direction. Indications of geological structures in the field are shown by the morphology of valley-ridges, in some places has a steep slope that form the fault escarpment and triangular facet. The FFD analysis results in the research area have varying permeability classes shown by low FFD values (0.00–3.00 km-1), medium (3.00-6.00 km-1) and high (6.00–9.33 km-1). The geothermal manifestations appear in the permeability zone that have medium to high FFD values marked by orange and red colors. From 3D micromine software modeling of the permeability zone and plotting of hot springs on the surface, it is clear that the appearance of hot springs to the surface is facilitated by faults that develop in the research area.

Abstract

The presence of geothermal manifestations in the form of hot springs is closely related to the presence of permeability zones in the Sumani geothermal system, West Sumatra. The permeable zone allows fluid circulation where meteoric water seeps to fill the reservoir and emerges on the earth's surface as a manifestation of hot springs. This study aimed to identify those permeable zones based on lineament density analysis using the Fault Fracture Density (FFD) method on ASTER GDEM satellite imagery. Lineaments in this case was assumed to be associated with fractures or faults in geothermal areas. The method was used to analyze the presence of lineament on topographic maps and to clarify all lineaments in the study area by adjusting the irradiation angle of 0°, 225°, 270°, and 315° at a constant altitude of 45°. From the FFD method, high lineament density values were found in the southwest of the study sites. The pattern of lineaments in the research area had northwest - southeast and southwest – northeast. The FFD analysis results were compiled with location of geothermal manifestations and geomorphological analysis which then showed positive results on the emergence of dominant hot springs depending on zones with high lineaments density and was located in the pyroclastic flow geomorphology unit with a difference in elevation between 500-1500 masl and slope of moderately steep to steep; indicating catchment area. Further research was needed to accurately understand about reservoir and the potential of geothermal reserves in the Sumani area.Keywords: Sumani Geothermal System, Fault Fracture Density, Geomorphological Analysis.

Abstract

Geothermal manifestations can occur in zones of high permeability. Permeability zones can be analyzed through lineament density, assumed to be associated with faults and fractures which are considered as weak areas that can allow geothermal fluid to pass from reservoir to the surface. This study intends to determine the zone with high permeability in geothermal manifestations. Modeling of surface data in the form of lineament pattern can be analyzed with Fault Fracture Density (FFD) analysis. The lineaments pattern is obtained based on the appearance through DEMNAS satellite imagery. The lineaments pattern deliniated by providing lighting from several angles, from lighting azimuths of 0°, 60°, 120°, 180°, 240° and 300° at a constant altitude of 45°. FFD analysis shows geothermal manifestations appear in the high permeability zone in the Sembalun area, Lombok.

Abstract

Indonesia is a country with quite large geothermal potential with a volcanic distribution that extends from Sabang to Merauke. The total potential for developing geothermal energy in Indonesia can reach 28,579 MWE if it is developed properly. This study was conducted for determining a permeable zone at the research location which is in Sukarame Village that can be related to the emergence of hot springs as a geothermal surface manifestations, besides that this research can also provide an overview of the general direction of geological structures that may develop in the research area. The method used in this study is Fault fracture density analysis which can determine the zone with a high level of permeability based on the lineament pattern drawn from remote sensing interpretation. The main data source for interpreting lineament pattern analysis is DEMNAS imagery which built from 3 satellites imagery including IFSAR, TERRASAR-X and ALOS PALSAR. The lineament pattern that have been analyzed then processed computationally into rose a diagram to get the general direction of structural geology which may develop. The total length of the lineament pattern is also calculated to obtain the lineament density value that leads to the determination of the permeable zone. The lineament pattern in the research area has a general direction of northeast-southwest, while the lineament density value in the study area has a value range of 4534.714078 – 9084.119758 m/km2. Areas with a high level of permeability coincide with the point of hot springs as a manifestation of the geothermal surface.

Abstract

In Indonesia, the COVID-19 disease has developed rapidly as found on April 20, 2021, there were 1,614,849 positive cases of Covid-19. The increase in cases of the coronavirus has resulted in an increase in the amount of medical waste during the Covid-19. The most common medical waste is face masks, both from hospitals and households. This increase in medical waste will cause environmental damage or health problems.  "A viable solution for reducing the impact of face mask waste on health and the environment is to recycle the face mask mechanically, chemically, and thermally. The proximate, ultimate, FTIR analysis and hardness testing have been carried out to obtain the potential for recycled products. The test results show that carbon ( C ) and volatile matter  (VM)are found in large quantities; polypropylene content is a detected type of plastic. Thus, recycled products can generate potential as a source of renewable energy, cement replacement materials, pipes, packaging materials.. Besides being able to produce new products, this process can also eliminate viruses.

Abstract

Coal is the richest source of energy used worldwide. Characterization of the structure of coal is one of the important things in studying the use of coal. X-Ray Diffraction (XRD) has been successfully used as a tool to study the molecular structure characteristics of coal with various coal ranks. There are five coal samples to be examined from the Bayah Formation in Lebak Regency, Banten. This study aims to measure the crystal structure parameters in coal and use them to predict coal maturity level. The results of XRD analysis showed that the five coal samples had the same crystal structure characteristics. The value of d002 is in the range of 3.87 to 3.96 Å, indicating that the studied sample has a low content of microcrystalline units. The measurement of carbon aromaticity (fa) values in the study area ranged from 0.67 to 0.76. There is a strong correlation between the value of coal maturity as measured by vitrinite reflectance (Ro) and the value of aromaticity; which is characterized by a correlation value of r of 0.88. Thus, the aromaticity (fa) value of XRD can be used to predict the maturity level of coal.

Abstract

The YR Geothermal Field is located in East Java. This field is associated with an active volcano, implying a potential for a high enthalpy geothermal system. This field is still in the exploration phase, but no drilling has been conducted yet. Thus, insights into the geothermal system are obtained through geochemical analyses of geothermal manifestations. Geochemical analyses were performed on hot spring water samples to determine the characteristics, processes, origin, and fluid flow of the geothermal system. The research results indicate that the warm springs have temperatures ranging from 29.4 to 54.8°C, with a nearly neutral pH (6.14-6.44) and high contents of HCO3 (457-1150 mg/kg), Na (77.7-255 mg/kg), and Mg (37.4-110 mg/kg). Therefore, it can be concluded that all the warm springs fall into the bicarbonate type with immature conditions, indicating no direct association with the reservoir. The upflow zone is interpreted to be at the peak of Mount 7, while the outflow zones are in areas A, B, and C. The fluids flow from the upflow zone, then condense and advectively flow down the slope, experiencing dilution and reactions with rocks before emerging as outflows in the western and north-western areas.
