Environmentally friendly thermal power plant based on the principle of a multi-product complex at vortex burning of the Berezovsky coal of the Kansko-Achinsk basin
Authors: Salomatov V 
Published: July 2020

Abstract
According to the Energy Program of Russia until 2030, the formation of coal power is associated with large thermal power plants on low-grade coals and supercritical steam parameters. An increase in the proportion of low-quality coal leads to a sharp increase in toxic emissions in flue gases, liquid effluents and ash and slag waste. The article considers the scientific and technical bases and circuit solutions for the creation of environmentally friendly thermal power plants (EFTPP) on the Berezovsky coal of the Kansko-Achinsk Basin (KAB) with vortex combustion technology based on the principle of a multi-complex with the production of not only the main products (electric and thermal energy), but additional waste with consumer properties. Multi-product complex (MPC) is a series of road construction plants and agricultural enterprises, associated with the TPP and efficiently using wastes for construction, metallurgy and various agricultural products. The performed calculations and analysis of technical and economic indicators have shown that with the existing equipment, prices and tariffs for the products, the EFTPP will pay off more than two times during the life cycle. After 8 years from the beginning of construction the MPC starts generating profit.

Abstract
In modern metropolitan cities, mass construction of multi-storied underground and closed-type above-ground garages of quite large areas with quite low ceilings (up to 3.5 - 2.5 m) is observed, which requires new approaches to the selection of the ventilation arrangement and its main technical characteristics. Jet ventilation systems have found extensive use. In 2018 in Kazan, an underground four-storied garage equipped with reversible jet ventilation and smoke extraction system (the first in Russia) was constructed and handed over to the customer. Taking into account the absence of any experience in Russia in the field of design and construction of jet ventilation systems, a comparative analysis of traditional duct ventilation systems and jet ventilation systems of closed (underground) car-parking spaces widely used all over the world has been performed. The choice of reversible jet ventilation is justified keeping in mind the parameters of energy efficiency and underground space development effectiveness. In this work, we have performed a critical analysis of ventilation systems with regard exactly to these parameters. Besides, we have shown the advantage of reversible jet ventilation in terms of ensuring safe evacuation of people in the case of fire. For the first time, we propose a scientifically grounded method of calculation of longitudinal jet ventilation and smoke removal system of the parking lot. As a result, design rules have been developed to ensure human safety in case of fire and energy efficiency in normal operation of the jet ventilation system.

Abstract
Bangladesh has a unique geophysical location at the northern apex of the Bay of Bengal. Waves originating in the Indian Ocean, are constantly travelling up the bay area and interacting with the Bangladesh coastlands. In order to estimate the major wave properties required for coastal engineering purposes, a 2D coupled Wave-Hydrodynamic model of the greater bay area was developed in this study, using the Delft3D modeling suite. The model was simulated for a year and from the model outputs, significant wave height was primarily assessed at multiple locations along the Bangladesh coastline. Considerable spatial variation was observed in the wave parameters, along the whole coast at different locations, with the south-eastern coastal region showing high trends of wave height; whereas in the deltaic south-western, and south-central zones, wave heights were rather moderate. Strong seasonal variation was also observed for the different parameters, as both wave heights and depth-average current velocity were very high during the wet monsoon season, compared to the lean winter period. The results of this study is expected to provide a reasonably sound characterization of the wave spectrum along the coastline of Bangladesh.

Authors: Chen Y C , Hu W J 
Published: July 2020

Abstract
Nowadays, LINE is one of the widely used communication software in Taiwan and fire protection work is also deeply affected through applying LINE. In this study, the Integrated Technology Acceptance Model (UTAUT) is applied to explore the behavior usage of LINE in assistance of fire safety works. A questionnaire survey is designed to explore the three aspects that affect the “behavioral intension”, such as “performance expectation”, “effort expectation” and “social influence”; and whether “usage behavior” is subject to “behavioral intension” and “facilitating conditions”. Moderator variables such as gender, age, experience and voluntary interference with each aspect are also explored. Through the statistical analysis, it is concluded that LINE’s assistance to fire safety works is definitely positive. “Performance expectation”, “effort expectation” and “social influence” can affect “behavioral intention” to be very significant; “behavioral intension” and “facilitating conditions” can also affect “usage behavior”. Among the different moderator variables: gender has no significant difference to each aspect. Age, working seniority and LINE experience have very or extreme significant differences on each aspect. Work unit and grades only have significant differences on some aspect. Voluntary has significant difference only in “social influence.”

Published: July 2020

Abstract
The mapping of active faults in Indonesia, especially in areas near the city center is very important to determine the building code. Mamasa Regency, West Sulawesi is one of the areas that have active faults, has not been mapped well in the 2017 seismic hazard book, which is a guidebook in creating building codes in Indonesia. A total of 762 earthquakes occurred in this area from November to December 2018. This study aims to map active faults associated with the source of these earthquakes. TOPEX satellite gravity data were processed to obtain the Complete Bouguer Anomaly. The residual and regional gravity values were separated using a Gaussian filter to identify the lineation of the fault and the existing fracture zone. The multiscale second vertical derivative was also implemented to identify and characterize the fault. Topographic contour mapping was carried out to confirm the presence of fault on the surface as well as to observe the direction of fault movement. We used seven focal mechanism data from Global CMT to support the interpretation result of gravity and topographic data. The result, the main fault is a sinistral strike-slip fault with N164E strike orientation. This strike-slip fault has two sides. The movement of the strike-slip fault on these two sides causes a pull-apart which results in normal faults in the pull zone between the two faults.

Abstract
Blawan-Ijen geothermal prospect area is placed at Bondowoso, East Java. Geologically, the presence of geothermal system in this field is controlled by the huge ancient Kendeng caldera complex structure. The heat source of the geothermal system is predicted to be situated at the base of Kendeng caldera. Geomagnetic method was used for detecting the presence of the heat source. The high temperature zone as the main target of geothermal exploration mostly situated around the heat source location. The geomagnetic method was applied because of its ability to identify the magnetic variation of rocks such as the demagnetized zone which is caused by the high temperature condition in geothermal area especially in the center of geothermal reservoir. Geomagnetic survey was conducted in 2017 and 2018 with the total of 151 stations. The 3-D inversion of geomagnetic data was then carried out to image the subsurface magnetic variation which is representing the complex structure of geothermal system in this area. The subsurface magnetic variation structure revealed by 3-D inversion showed the distribution of demagnetization reservoir rock inside the Kendeng caldera which has low magnetic susceptibility. In the upper part of this layer that is a higher magnetic susceptibility layer which may associated with the clay alteration that is overlaying the geothermal reservoir in this area. Moreover, the very low magnetic susceptibility anomaly can be observed start from -1000 m elevation, which is interpreted as the heat source of the geothermal system in this area.

Abstract
Fish substitution in fish fillet products is a concern in food safety and sustainability. There are many reports about the mislabeling problem in fish fillet products. DNA-based identification plays an important role in food safety and traceability. The use of advanced techniques of barcode using multiplex PCR for species identification substitution from fish fillet products are demonstrated in this study. The primer was designed from three different species that are usually labeled in fish fillet products. Each pair of primers were designed to amplify different PCR products that are specifically recognized as different species. We found 11, 6 and 0 samples labeled as Tilapia, Pangasius, and Snapper respectively. This method is suggested for rapid identification because it is efficient and accurate.

Abstract
Introduction of alligator gar (Atractosteus spatula) into a new range of its distribution has been reported in several freshwater ecosystems. The presence of alligator gar in Indonesia has been recorded in Jakarta during big flood in 2007. The concern about introducing this species is because of its predatory behavior and can impact the trophic system in freshwater ecosystem in its non-native range. Here, we demonstrated two methods, conventional and kit method, to maximize eDNA concentration in addition to detect the presence of alligator gar in freshwater ecosystem. We used mesocosm study to mimic the real condition of freshwater system in tropic region. We found that both methods can extract eDNA from water samples. The kit showed better yield of eDNA with average concentration 62.28 ± 22.27 ng/μL than conventional method with average concentration 19.35 ± 9.89 ng/μL. Another advantage of the kit method was better purity of eDNA, with average purity 1.92 ± 0.05 compared to conventional method with average purity 2.23 ± 0.42. The better concentration and purity of eDNA could be advantageous for further analyses such as PCR and DNA sequencing.

Published: July 2020

Abstract
Mislabeling of fish fillet product is one of the key issues in food safety and sustainability. Species identification is an important step of fish fillet traceability and DNA barcoding has been proved as a standard method. Fourty seven 47 fish fillet products were collected from modern and traditional markets in the Jabodetabek area. DNA barcoding was used to analyze the compliance of the product label. This research also highlighted that near threatened (NT), Vulnerable (VU), endangered (EN), and critically endangered (CR) species considered to be facing a high risk of extinction have been used as a substitution in fish fillet product. The application of DNA mini-barcoding gives better resolution in species identification for commercial species. From this research, we found that there are some mislabeled fish fillet products, including blue shark meat that is listed as Near Threatened in IUCN Red List in one of the products.
Unintended consequences: Factors influencing oil palm plantation expansion
Authors: Wongsai S , Keson J , Wongsai N 
Published: July 2020

Abstract
We investigated the landscape variables affecting the current dramatic expansion of oil palm plantations in Lam Thap district Krabi Province Thailand. THEOS satellite data was used to map land use classifications using the support vector machine method. Seven land use classes were consolidated into oil palm plantations and other rural uses. A logistic regression model was then applied to search for the relationship between two land use classes and the landscape variables of slope (three classes) and soil drainage (four classes). Overall, slope and drainage were statistically significant in explaining oil palm plantation expansion. Flat areas with poor drainage were the strongest factors. This contradicts the known optimal agronomic requirements for oil palms of well drainage. We suggest that what is observed is an unintended consequence of government oil palm support policies.

Abstract
Integrated measurements of magnetic and gravity methods were carried out over Blawan-Ijen Geothermal Prospect area to discover the indication of prospect zone location more convincing. The acquisition was first conducted in 2017, followed by recent measurement in 2018 with a total of 151 stations for each method. In this research, Reduce to Pole for magnetic data was applied to identify the distribution of demagnetized rock which associated with reservoir zone. The prospect zone is usually indicated by low magnetic susceptibility value. Furthermore, to support the interpretation of prospect zone which usually located overlying the heat source, then 3D inversion of gravity data was conducted. Thus, by applying 3D inversion of gravity method, the distribution of density variation beneath the earth surface which represents the location of heat source can be obtained. The result of Reduce to Pole of magnetic data shows demagnetized zone with low magnetic susceptibility value located in the centre to the southeast at the study area. Moreover, 3D gravity data inversion delineates the existence of heat source indicated by high gravity anomaly which corresponds with demagnetized zone shown from magnetic data.

Published: July 2020

Abstract
The Tidal wave is one of the main factors that producing sedimentary structure and agent of erosion. Study further about it can help for local people living in the coastal area and for academic learning. The tidal wave was replicated using a flume tank. The sand used is fine-grained that taken from Sawarna beach. To obtain the quantitative Digital Elevation Model (DEM) was used. The DEM data were taken using a laser distance meter after the experiment. Reynold’s Rule was used for scaling down the variable that happens in nature to the experiment scale. There are 3 significant changes as a result of this experiment. First, the sediment was sorted according to the grain size of the sediment. Second, the slope of the coast has changed which is measured by DEM. Third, the sediment structure was created which has a similarity with the one created by nature. So, the result was a proof that Reynold’s scaling down methods can be used to scale down a sedimentary process that happens in nature. This research explains what exactly happens in the formation of a sedimentary structure.

Published: July 2020

Abstract
Sequence stratigraphy was a study of layered rocks that form in some period of time. It was proven to be a useful tool in industry, especially oil industry. Yet, sequence stratigraphy most people have seen was the result, not the process. Of which, this study wanted to replicate the process that was taken place in sequence stratigraphy in a smaller scale of a laboratory. To replicate sequence stratigraphy, this study used a flume tank device filled with sand and water flowing with controlled rate. This study makes changes in water level in the flume tank to affect accommodation space, on which sedimentation happens, thus, making some morphological change known as progradation and retrogradation. Changes were recorded using time lapse camera and measured using laser distance meter to see how much the morphology had changed after some period of time. Result of this study showed that transgression and regression could be replicated inside the flume tank by changing the height of water level. Though the time scale could not be made close to real condition, but the process and the result could. This would help understanding sequence stratigraphy not only from the outcrop but also from the series of the process that made it.

Authors: Riyadi P , Supriyanto  , Purba H 
Published: July 2020

Abstract
The WR field in this study is a gas hydrocarbon proven field with high saturation rate and reservoir character in tight sandstone. There are prestack 3D seismic data and three well data that have P-wave velocity (Vp) and S-wave velocity (Vs). In its development there are three kind of methods using Vp, Vs, and angle function constants that is Extended Elastic Impedance (EEI), Poisson Impedance (PI), and Curved Pseudo Elastic Impedance (CPEI). By using correlation coefficient concept between two kinds of variable, we can look for the angle function constants which used in those three methods. The results obtained from those three methods correlated with lithology log data (Gamma ray (GR)) at the range of angle (-90° to 90°) is EEI = 30°, PI = 59° and CPEI = -69°, whereas with fluid log target (Water Saturation (SW)) obtained angle values correlated with EEI = 20°, PI = 51° and CPEI = -60°. The highest correlation to the target lithology (GR) and fluid (SW) log data of the three methods is CPEI with correlation 0.881 for lithology and 0.604 for fluid. The vertical of the three methods shows a good reservoir character with high saturation rate of gas. The result of the lateral distribution of the three methods shows the character of the depositional environment in the target reservoir located in the estuarine environment in upper shoreface facies for Reservoir A and transition facies for Reservoir B. The direction trend of the source of the sedimentary sediment is the south-east direction, and this result fits with the regional geological concept in the WR field.

Authors: Sulistyo A , Daud Y 
Published: July 2020

Abstract
Blawan-Ijen is a caldera hosted geothermal system that located in Bondowoso, East Java. To delineate the existence of the geothermal system of Blawan-Ijen, gravity and geomagnetic studies were conducted. Since no impressive manifestation in this area, to delineate the prospect area is very challenging. Both methods are used to detect the presence of basements and potential heat sources. Gravity data processing was processed to obtain CBA and residual gravity anomalies, while geomagnetic data was processed until reduce to pole. The results of data processing are used for 3D inversion of gravity and geomagnetic data to find out anomaly distribution horizontally and vertically. To understanding potential heat source, 3D inversion results are displayed at an elevation of 500 m to 1,000 m. The existence of resources using the geomagnetic method is represented by a low magnetic anomaly value as an indication of demagnetized rocks, but high gravity anomalies are seen in the demagnetization area. The potential heat source from gravity and geomagnetic interpretation located in the center of the Blawan-Ijen geothermal prospect, that is the northern part of the south mountainous area, those areas are located around Mt. Gendingwuluh and the northern part of Mt. Genteng and Mt. Glaman.
