Abstract
CO2 flooding is an effective technique for enhancing oil recovery by changing the hydrocarbon fluid’s characteristics. One of the fundamental mechanisms of the interaction between CO2 and hydrocarbon fluid by miscible CO2 injection is the extraction phenomenon of the hydrocarbon components by CO2. It results in altered produced and residual oil characteristics. This study aims to examine the characterizations of produced oil during the process of CO2 displacement. It is critical to anticipate any issues that can arise from miscible CO2 flooding, such as asphaltene deposition. A light-dead oil sample from an Indonesian oil field was used in this investigation. The miscible CO2 displacement process was conducted by a slim tube experiment at operating temperature of 90°C and 70°C, which represents the reservoir and surface temperature, respectively. The properties of produced oil were further characterized by analyzing the composition based on its polarity, including saturate, aromatic, resin, and asphaltene. The results show that increasing injection pressures decrease resin and asphaltene fractions in produced oil. Furthermore, the proportions of asphaltene and resin fractions in the crude sample exhibit a significant decrease when conducted at a lower temperature in comparison to when carried out at a higher temperature. This study helps to explain how the displacement process by CO2 affects the properties of the produced oil.

Abstract
The majority of oil wells in the Tanjung Field are old wells with reservoir characterized by low pressure and temperature, as well as high water production. The characteristic of oil in the Tanjung Field has a relatively high wax content of 17.61%. This condition has led to several wells in the Tanjung Field experiencing issues with the simultaneous formation of wax and scale deposits within the wellbore equipment. The simultaneous occurrence of wax and scale can significantly impact the production rate. Therefore, addressing this production issue efficiently requires a method known as wax scale removal (WSR). WSR can effectively tackle the problem of wax and scale deposits occurring simultaneously in production equipment. In this method, a solvent for dissolving wax deposits and an acid for dissolving scale are injected together using the huff and puff technique.

Abstract
Gasification characteristics of Meulaboh coal have been investigated using chemical, petrographical, and thermogravimetry–mass spectrometry (TG-MS) approaches. The coal is classified as sub-bituminous C and dominated by huminite maceral (77% vol.). Based on proximate analysis, the coal comprises 12.56% moisture, 17.36% ash, 38.92% volatile matter, and 31.16% fixed carbon (adb). The coal is low in rank and dominated by reactive maceral. Thus, it is suitable for gasification study. TG-MS measurement revealed that the main pyrolysis product consists of H2O, CO2, and CH4, which generated significantly in slow and fast pyrolysis stages (180-294°C and 194-529°C, respectively). Gasification was performed using limited synthetic air and CO2 environments. TG and DTG thermograms show that gasification using CO2 resulted a higher mass loss rate than that using limited synthetic air. Moreover, gasification in a limited air atmosphere produced higher contents of H2O and CO2, while gasification in a CO2 atmosphere produced primarily CO.

Abstract
Mine slope design is an important part of mining operations because it is used to determine the balance between mine economy and operational safety. In the mine slope design there will also be a groundwater level design, the groundwater level is one of the triggers for a slide to occur. Therefore, this study aims to determine the effect of the groundwater level on the stability of the highwall slope cross section A-A’ as well as to determine the factor of safety value and probability of slope failure under various conditions of high groundwater levels. This research method uses quantitative methods because there are numerical data that will be used to calculate the value of slope stability. Slope stability analysis uses the “morgenstern-price” boundary equilibrium and the “monte-carlo” landslide probability. From the research results it is known that the higher the groundwater level, the lower the safety factor value because the presence of groundwater can reduce slope stability causing a decrease in soil shear strength due to increased pore water pressure. In addition, the weight of the material will increase due to the presence of groundwater, which causes the driving force on the slope to also increase. In addition, the movement of air in the soil can cause seepage forces which can affect slope stability. The lowest safety factor value is at the groundwater level 100% of the overall slope height, in conditions of 100% of the overall slope height, the deterministic safety factor value is 1.337, the mean safety factor is 1.358, and 0% hazard susceptibility.

Abstract
Coastal areas have the potential for damage caused by abrasion, strong winds, and tsunamis. Seeing the high potential for damage that might occur, the appropriate approach is to conserve mangrove forests, one of which is found in Jangkaran Village, Temon District, Kulon Progo Regency. This study aims to identify mangrove community structure and aquatic environmental factors in Jangkaran Village. Mangrove community structure was analyzed using the importance value index and the Shannon-Wiener diversity index. Aquatic environmental factors were analyzed using temperature, pH, dissolved oxygen, and salinity parameters. Data collection was carried out in three locations in Jangkaran Village. Mangrove vegetation data were taken from each transect using the 10 m x 10 m quadrat transect method. Data on aquatic environmental factors were taken directly at the location using a refractometer, DO meter, and pH meter. The results of this study are species with the highest importance index value in location 1, namely Rhizophora apiculata (117.094%), location 2, Avicennia marina (207.203%), and location 3, Avicennia marina (97.0362%). Shannon Wiener diversity indexes in the three locations are 0.6943, 0.4056, and 0.6841. The results of measurements of aquatic environmental factors are temperature 25.7-30.3 °C; pH 7.2-7.7; salinity 25-34; and dissolved oxygen 6.5-6.7. Thus mangrove diversity in Jangkaran village is included in the low category and the aquatic environmental factors is favorable for mangrove growth so that the mangrove ecosystem can be further developed.

Published: May 2024

Abstract
Indonesia with energy dominance from fossil (non-renewable) sources is expected to last until 2050. As a signatory to the Paris agreement, Indonesia has the duty to reduce the release of CO2 into the atmosphere, which means that the country cannot depend on fossil fuel sources such as oil and coal. Moreover, the Indonesian government is currently targeting an ambitious use of renewable energy of 23% of total energy sources. To achieve this target, the government has increased the renewable energy program. The energy transition has been widely discussed as part of global initiatives to reduce the impact of climate change, since the climate crisis is intensifying and causes many disasters. Indonesia has published an Indonesia Long Term Strategy for Low Carbon and Climate Resilience (LTS-LCCR 2050) and a National Determined Contribution (NDC 2021) document to incentivize the energy transition. The purpose of this research is to carry out a literature study approach related to renewable energy application and challenge in order to support the acceleration of the energy transition in the midst of increasing the disaster due to climate change in Indonesia. Gas emission cause more extreme weather as climate change could delay the energy transition. These findings summarize the energy transition and provide insights solution by incorporating climate adaptation into strategies that reduces carbon emissions, including renewable energy deployment. The application of renewable energy on energy transition has an implication on local, regional, and national level.

Abstract
Dams offer significant benefits such as power generation, flood control, irrigation, and tourism. However, when mismanaged, they pose a high risk of catastrophic failure, potentially releasing large volumes of water rapidly, resulting in severe downstream damage, environmental impacts, injuries, and loss of lives. Effective dam monitoring is essential to evaluate slope stability, detect slope behaviour changes, and deliver early warning for potential hazards. Upon detecting any deformations in the dam or its watershed areas, prompt interventions can be initiated. Interferometric Synthetic Aperture Radar (InSAR) is the measurement technique of signal phase change between two images at the same location and at different times, it will be a proficient method for monitoring ground or slope changes across vast areas without the installation of on-site instrumentation. The dataset used in this work consists of 392 images of Sentinel-1 from 1 September 2018 to 11 August 2023 to conduct long-term InSAR data analysis. Monitoring the dam and its watershed is crucial, given that over 30% of U.S. dam failures result from overtopping. Slope failure events at the upstream area can cause abrupt water level rises, further increasing the risk of overtopping and major instability. This study explores slope deformation around dams and their watersheds using satellite long-term InSAR technology using a study case from one of the dams in Indonesia. The outcomes will provide insights into dam safety and shed light on the strengths and constraints of the InSAR technology.

AbstractSludge (tailing), a waste product of the amalgamation process used in the mining of gold, contains a high concentration of the heavy metal mercury (Hg). It is well known that mercury builds up in large quantities inPlectranthussp. herbaceous plants in the Pancurendang Village Small-Scale Gold Mining area. The study intends to: 1) quantify the amounts of mercury present in plant organs and media tailing during phytoremediation treatment; 2) examine the mechanisms and capacities of plant phytoremediation using values of the Biological Accumulation Coefficient (BAC), Biological Concentration Factor (BCF), and Translocation Factor (TF); and 3) determine the impact of percentage variations in tailing and time onPlectranthussp.’s capacity to accumulate mercury. On a lab scale, phytoremediation of tailings is done with concentrations of 0%, 30%, 50%, and 100%. Planting medium is combined with dried tailings. Pots are used for phytoremediation, and the residence times are 10, 20, and 30 days. With the use of a mercury analyzer, the amount of mercury present in plant media, roots, and shoots is determined. Using the BAC, BCF, and TF values, the mathematical calculation of phytoremediation ability is performed. Hg content ranged from 1.82 to 16.23 ppm in shoots and 5.15 to 37.19 ppm in roots. Throughout the course of treatment, the tailings Hg concentration varied between 13.18 and 220.05 ppm.Plectranthussp. is categorized as a medium accumulator with a phytoextraction mechanism, according to the analysis’s findings. Hg phytomining is possible withPlectranthussp., the TF value is 2.38. Within 10 days,Plectranthussp. most effectively accumulates 50% Hg in tailings.

Published: May 2024

Abstract
Mn and Fe are common metallic elements found in wastewater. In high concentration these elements can cause environmental and health risks. This study was conducted to examine the improvement of natural calcareous bentonite (NCB) adsorption capacity on Mn and Fe in aqueous solution after high-temperature calcination. The NCB sample was prepared in three conditions: untreated, calcined at 200 °C and 800 °C. The Mn adsorption test showed the calcined sample at 200 °C had no significant differences uptake to the untreated with an increase in pH from 3 to 7 in one hour and reached the equilibrium in 24 hours. Disparately, the calcined sample at 800 °C showed much higher Mn uptake, immediate equilibrium, and an extreme increase in pH from 3 to 11 just in one hour. The Fe adsorption test for three sample conditions exhibited immediate Fe uptake and equilibrium within just one hour, with no differences in Fe uptake. However, the pH in equlibrium time had different increase. The untreated and the calcined sampel at 200 °C had an increase pH from 3 to 7 while the calcined sample at 800 °C had an increase pH from 3 to 11.

Published: May 2024

Abstract
The exploitation of petroleum in Wonocolo is conducted with traditional equipment, leading to contamination by oil spills. Oil Spill contamination has the potential damage to ecological, soil, and surface water, caused by the hydrocarbon content itself. Total Petroleum Hydrocarbon (TPH) test results on contaminated soil show the highest value at 17.4%. Experiments were carried out to analyze the effectiveness of soil washing using Alky Benzene Sulfonate surfactants to reduce the TPH number. Experiments are conducted with variations in surfactant concentrations such as 0%, 0.25%, 0.50%, 0.75%, and 1%. The results of the Soil Washing experiment showed that the surfactant concentration with the highest effectiveness was at a concentration of 0.25%. Concentration of 0.25% reduces TPH by 9% with 51.72% effectiveness.

Abstract
The study was conducted to analyze the trends in the development of research in the field of air quality management from 1983 to 2022. The study aims to find out the developments of scientific publications from year to year, the authors who dominate, the dominant countries, and the opportunities for innovation in research topics related to air quality strategy. Data collection was done by searching through Scopus with the keywords management OR strategy OR monitoring AND “air pollution” OR “air quality” AND “particulate matter” OR pm OR pm10 OR pm AND 2,5 with the category, article title, abstract, and keywords. The data is analyzed in terms of the number of publications per year, authors, origin of authors, and subjects with Ms. Excel. Whereas trends in publication development are analyzed using software such as biblioshiny and vosviewer. The results of the study show that in the period 1983-2022, research on air quality management strategies has undergone significant progress. The highest publication development began in 2019, with the production of over 100 annual scientific articles. Some of the main authors are Zhang Y, Wang Y, Wang X, Zhang X, Liu Y, and Wang J. The results of this study revealed gaps in spatial distribution where most of the research was conducted in China, the USA, Canada, the United Kingdom, India, and Spain, as well as some European countries. However, it could be an opportunity for researchers from lower income countries like Indonesia to do similar research. Topics that have not been much discussed and studied are topics about mapping, spatial analysis, modelling of air pollution, and dynamic systems for air quality management strategies.

Published: May 2024

Abstract
Nonlinear light-matter interactions have emerged as a promising platform for various applications, including imaging, nanolasing, background-free sensing, etc. Subwavelength dielectric resonators offer unique opportunities for manipulating light at the nanoscale and miniturising optical elements. Here, we explore the resonantly enhanced four-wave mixing (FWM) process from individual silicon resonators and propose an innovative FWM-enabled infrared imaging technique that leverages the capabilities of these subwavelength resonators. Specifically, we designed high-Q silicon resonators hosting dual quasi-bound states in the continuum at both the input pump and signal beams, enabling efficient conversion of infrared light to visible radiation. Moreover, by employing a point-scanning imaging technique, we achieve infrared imaging conversion while minimising the dependence on high-power input sources. This combination of resonant enhancement and point-scanning imaging opens up new possibilities for nonlinear imaging using individual resonators and shows potential in advancing infrared imaging techniques for high-resolution imaging, sensing, and optical communications.
Data-driven design of high pressure hydride superconductors using DFT and deep learning
Authors: Wines Daniel , Choudhary Kamal 
Published: May 2024

AbstractThe observation of superconductivity in hydride-based materials under ultrahigh pressures (for example, H3S and LaH10) has fueled the interest in a more data-driven approach to discovering new high-pressure hydride superconductors. In this work, we performed density functional theory (DFT) calculations to predict the critical temperature (Tc) of over 900 hydride materials under a pressure range of (0–500) GPa, where we found 122 dynamically stable structures with aTcabove MgB2(39 K). To accelerate screening, we trained a graph neural network (GNN) model to predictTcand demonstrated that a universal machine learned force-field can be used to relax hydride structures under arbitrary pressures, with significantly reduced cost. By combining DFT and GNNs, we can establish a more complete map of hydrides under pressure.

Published: May 2024

Abstract

Purpose
This article describes the implementation and evaluation of pharmacogenomic testing within the hematology/oncology ambulatory care clinic at the William S. Middleton Memorial Veterans Hospital in Madison, WI.

Summary
The Pharmacogenomic Testing for Veterans (PHASER) program provides preemptive pharmacogenomic testing for veterans nationally. Program implementation at the Madison Veterans Affairs site began in the hematology/oncology clinic with the goal of integrating the offer for pharmacogenomic testing, testing completion, and review of the results by the hematology/oncology clinical pharmacist practitioner (CPP) into current workflows to create a sustainable process for PHASER. The hematology/oncology CPP designed workflows outlining how testing would be offered to patients, how results would be reported and to whom, and how documentation would occur in the electronic medical record. Veterans are offered preemptive PHASER testing, before needing therapy requiring pharmacogenomic results. Exceptions to pharmacogenomic testing were patients with a history of liver or allogeneic hematopoietic stem cell transplantation.

Conclusion
This article provides a summary of the role of the hematology/oncology CPP in the implementation of a pharmacogenomics service and the impact on medication management in a hematology/oncology clinic.

Abstract
Aggregation of the RNA-binding protein TAR DNA binding protein (TDP-43) is a hallmark of TDP-proteinopathies including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). As TDP-43 aggregation and dysregulation are causative of neuronal death, there is a special interest in targeting this protein as a therapeutic approach. Previously, we found that TDP-43 extensively co-aggregated with the dual function protein GEF (guanine exchange factor) and RNA-binding protein rho guanine nucleotide exchange factor (RGNEF) in ALS patients. Here, we show that an N-terminal fragment of RGNEF (NF242) interacts directly with the RNA recognition motifs of TDP-43 competing with RNA and that the IPT/TIG domain of NF242 is essential for this interaction.
Genetic expression of NF242 in a fruit fly ALS model overexpressing TDP-43 suppressed the neuropathological phenotype increasing lifespan, abolishing motor defects and preventing neurodegeneration. Intracerebroventricular injections of AAV9/NF242 in a severe TDP-43 murine model (rNLS8) improved lifespan and motor phenotype, and decreased neuroinflammation markers.
Our results demonstrate an innovative way to target TDP-43 proteinopathies using a protein fragment with a strong affinity for TDP-43 aggregates and a mechanism that includes competition with RNA sequestration, suggesting a promising therapeutic strategy for TDP-43 proteinopathies such as ALS and FTD.
