Authors: Setiyoko Agus , Perwita Sari Yuli
Published: May 2024

Cowpea (Vigna unguiculata L.) has limited characteristics since it has a high content of antinutritional properties. The pretreatment process by a combination of germination and roasting of cowpeas, called pretreated cowpea was done to prepare the flour made from cowpeas. The purpose of the study was to investigate how the pretreatment of cowpea flour affected the antioxidant content and other characteristics of white bread. This study used 0-10.4% (w/w) of the flour as a wheat flour substitute for making white bread. The dough was baked at 175°C for 40 minutes. The results showed that substituting pre-treated cowpea flour affected the bread colour, volume expansion, total phenolic content as well as antioxidant capacity. Pre-treated cowpea flour enhanced the total phenolic compound, antioxidant activity, moisture content, and darker colour, whereas the expansion rate was reduced. The best formula was found by using 5.2% of pretreated cowpea flour. It has good characteristics at colour properties, volume expansion by 12.14%; moisture content was 27.62%, total phenol was 86.24 mg GAE/100 g, antioxidant activity was 29.67 %RSA, and sensory score was 3.75 (preferred). Therefore, the pre-treated cowpea flour can be utilized as a natural antioxidant source in white bread recipes.

The increase in egg-laying chicken population must be balanced with the increase in productivity. The productivity (quantity of eggs produced), which affects profitability, can be obtained with sufficient and high-quality drinking water (determined by its pH levels). One of the poultry farms in Jember, Rizqie Farm Partners, experienced a problem with the management of water and feed provision for the egg-laying chicken especially in rainy seasons. The farm is located in an open space and is approximately ±25 meters from the owner’s house, making monitoring and controlling of the drinking water irregular. It is pivotal to be disciplined in controlling the drinking water so that the chickens do not become stressed. The objective of the study is to develop a smart automated system for monitoring drinking water to increase the quality and quantity of egg production. Sensor data connected to the Arduino Uno was converted to an Android smartphone as a controlling and monitoring medium. The stages carried out included problem identification, literature study, data collection, system creation using the design sprint software development method, testing, and data analysis. The pH sensor test results on bottled mineral water, tap water, orange juice, water mixed with soil, and water mixed with vitamins for chickens were 3-8.27 for each type of water. The pH indicator paper as a comparison of the results with the sensor has an accuracy level of 85.06% and an error value of 14.94%.

The Lamongan Volcano Complex has a very different character from the Bromo and Argopuro Volcano groups. Lamongan Volcano has 37 volcanic cones and 27 maars (ranu). This volcano is quarter-old and occupies part of East Java Province. Maar Bethok is composed of lava and intercalation between pyroclastic deposits from phreatomagmatic and magmatic falls that still need to be firmly consolidated. These pyroclastic deposits characterize a strombolian eruption with more lava dome or crater wall material ejected. The rocks that make up the Bethok maar include olivine-pyroxene basalt lava and pyroclastic fall deposits with fragments of olivine basalt and basalt composition. The evolution of the Bethok maar eruption started from magma with an alkaline composition and ended with a more acidic composition. The magmatism of Bethok maar has an island arc calc-alkaline affinity.

Groundwater is vital element for living. One of methods to identify groundwater potential is Electricity Resistivity Tomography (ERT). This study aims to identify the groundwater potential occurrence in Sleman, Yogyakarta through non-destructive geoelectrical surveys. Based on the ERT models and geological information, supported by hydrogeological data in the research area, drilling a well at the planned location was deemed necessary to reach a depth of at least 100 to 250 meters in order to tap into the maximum groundwater potential. Groundwater is predicted to flow and accumulate in the pores and fractures of rocks. Well drilling in the northern part of section line 1 was more favourable and recommended due to the lower elevation compared to the area of section line 2, where the drill location was originally planned at a higher elevation uphill. Layers of hard rock, presumably lava and breccia, have already been found at a depth of 5 to 15 meters based on historical open well excavations around the area. Identifying the characteristics of subsurface volcanic rocks during drilling is suggested to evaluate drilling and well planning. Well logging should be conducted to collect lithostratigraphy and rock mass information. Further tests of hydraulic conductivity for each potential layer.

Published: May 2024

In offshore drilling activities, the employment of seawater mud is indispensable, and its adoption is steadily increasing. Traditionally, attapulgite has held a dominant position as the key element in seawater mud composition. However, a shift is underway towards substituting attapulgite with bentonite owing to the manifold advantages that the latter presents. Bentonite boasts favourable viscosity characteristics and efficient control over water loss, outperforming attapulgite particularly in terms of its capacity for clay absorption. Nevertheless, to harness its thickening capabilities for use with seawater, bentonite necessitates a preliminary hydration process. The pre-hydration procedure involves the amalgamation of seawater and bentonite at a low mixing speed for a duration of 10 minutes, succeeded by a resting interval spanning 16 hours. The integration of this pre-hydrated bentonite system necessitated an extensive research undertaking, encompassing a comprehensive review of pertinent literature, the collection of seawater samples, laboratory experiments conducted at three distinct temperatures comparing both fresh water and seawater formulations, the incorporation of diverse additives to augment the assessment of the mud’s physical attributes, meticulous measurement of the drilling mud’s physical properties, implementing treatments to enhance measurement values under heightened temperatures, meticulous analysis of acquired data, and the comprehensive documentation of research findings in scholarly publications. The crux of this research endeavour lies in attaining the objective of incorporating pre-hydrated bentonite as a pivotal constituent within seawaterbased drilling mud. The realization of this goal hinges on the congruence of the measured physical properties of the drilling mud with predefined specifications. Through a rigorous exploration of these methodologies and a systematic approach to research, the study endeavours to foster advancements in seawater-based drilling mud formulations and their operational effectiveness within offshore drilling contexts.

Published: May 2024

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.

Published: May 2024

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.

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.

Published: May 2024

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.

Published: May 2024

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.

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.

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

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.

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

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

The 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

This chapter offers a brief summary of current debates on the protection of heritage in war and current international law. It describes some theoretical limits and defines key terms. It outlines some theoretical assumptions of the book: that there are moral facts, that some form of non-consequentialism is true, and that the moral principles that govern war are the same as those that obtain outside of war. It offers some brief remarks on the methodology of the book, including our use of stylised examples. The chapter also provides a chapter-by-chapter outline of the argument.

Authors: Dreischmeier Emma , Hecht Hannah , Crocker Edward , Seckel Ellina , Wilcox Andrew , Fletcher Christopher , Piccolo Jennifer
Published: May 2024

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.

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.

Published: May 2024

This article investigates how living with, and self-managing, acne and post-inflammatory hyperpigmentation and scarring impacts adults living with these conditions. Eight adults took part in individual qualitative interviews. Framework analysis generated four themes: (1) acne blame; (2) control at any cost; (3) the business of skinfluencers; and (4) ‘it’s your hormones’. Those with acne and PIH&S are currently underserved by dermatology and psychodermatology provision, and additional funding and research is needed to provide psychological and self-management support for this group.

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.
