Technological progress has brought about modifications in the educational process. This transformation has led to numerous technological innovations for supporting student learning, with smartphones being one of the prominent tools. Despite the widespread use, students have primarily used smartphones for online gaming and social media, leading to a decline in the effectiveness for educational purposes. Therefore, this study aimed to explore how students in electronics engineering education responded to a novel technology, augmented reality (AR), when integrated into the fundamental learning process, in order to maximize the utility of smartphones. A cross-sectional survey approach with a quantitative methodology comprising 101 students in the field of electronics engineering education in higher education institutions in Indonesia was adopted. Data were collected through a questionnaire, which was subsequently analyzed using the Structural Equation Model (SEM) method with SmartPLS 3 software. Additionally, this study used Fuzzy C-Means (FCM) clustering method to examine the influence of each cluster values on the others. The analytical results showed that Computational Thinking Skill (CTS) of students significantly impacted Actual System Use (ASU) of AR. Furthermore, perceived usefulness (PU) and perceived ease of use (PEU) of this technology played crucial roles as mediators in ASU of AR.

This study assesses the effectiveness of merging project-based learning (PjBL) with STEAM education in metal welding curricula for 64 vocational students at Universitas Negeri Padang over 11 sessions. A quasi-experimental design with pre- and post-tests compared the performance of a PjBL-STEAM experimental group to a traditionally taught control group. The PjBL-STEAM approach significantly outperformed traditional methods, evidenced by higher mean N-gain scores in cognitive (0.763), affective (0.772), and psychomotor (0.759) domains, indicating its high effectiveness. Consequently, it is deduced that educational projects that amalgamate the STEAM approach yield more profound advancements in student academic outcomes than those conducted through conventional means. The procedural intricacies of the PjBL-STEAM syntax are meticulously elucidated, serving as a vital resource for educators and students alike in implementing this methodology within lecture settings and equipping students with pertinent competencies for the 21st-century workforce in the welding sector.

Purpose of this work is the comparative analysis of two approaches to the synthesis of two-dimensional binary identifiers of nucleotide sequences obtained using DNA sequencing of biological objects. Methods. One of the approaches is based on modeling the polarization-dependent diffraction of a coherent readout beam on a two-dimensional phase-modulating structure (phase screen) associated with the symbolic sequence obtained as a result of DNA sequencing. Another approach uses a two-dimensional representation of the symbolic sequence using a chaos game representation (CGR). To obtain a finite-element CGR mapping, it is fragmented into a given number of cells, ensuring acceptable sensitivity of the synthesized binary identifier to structural changes in the displayed sequence. Results. The comparative analysis was carried out using fragments of symbol sequences corresponding to various strains (Wuhan, Delta, Omicron) of the SarSCoV2 virus. In the course of the analysis, the correlation coefficients between the binary identifiers corresponding to various strains were obtained and compared with each other. Conclusion. It has been established that binary identifiers synthesized using the polarization encoding technique are characterized by significantly higher sensitivity to structural changes in the analyzed sequences and smaller sizes compared to CGR binary identifiers.

Authors: Aprina Fenty
Published: May 2024

Vaccination against Covid-19 is one of the most important steps adopted by the government to limit the spread of the virus in the community by establishing population immunity. According to Ministry of Health data, Covid-19 vaccination coverage has reached 92% of the population until 2023; however, there are still various obstacles to overcome in its implementation, ranging from the initial feasibility trials to the distribution and acceptance of the Covid-19 vaccine at various levels of society. These obstacles have resulted in varying degrees of success in receiving the Covid-19 vaccination in various countries and provinces around the world, including Indonesia. This study aims to find out how successful the response to a pandemic is through establishing population immunity and involving all components of the government, TNI/Polri, agencies, and the community/NGOs in handling the pandemic in the implementation and acceptance of the Covid-19 vaccine in Indonesia since it was first tested and distributed. This research uses the literature review methodology. Researchers analyzed various articles with the keywords “factors affecting Covid-19 vaccine acceptance,” “collaboration in Covid-19 vaccine,” “TNI role in Covid-19 vaccine,” and “government role in Covid-19 vaccine” from various international open sources such as Elsevier, MDPI, ScienceDirect, Frontiers, Tandfonline, and Google Scholar. Articles relevant to the theme and research objectives were selected, analyzed, and grouped based on the researcher’s requirements. The findings of the literature review show that the roles of and collaboration between public components, including the government, the Indonesian National Police, agencies, and the community, have an impact on the success of the Covid-19 vaccination in Indonesia. The government’s role is to establish communications and campaigns to boost public confidence in the benefits of the Covid-19 vaccine. Furthermore, the role of the TNI/Polri is to ensure the implementation of disaster management in a planned, integrated, coordinated, and comprehensive manner, while the role of agencies/NGOs is to encourage advocacy activities and distribution networks for receiving the Covid-19 vaccine. Each component plays a role that positively influences vaccination acceptance in the community, so collaboration between components is required for the success of the Covid-19 vaccine activity in Indonesia.

Published: May 2024

This research aims to analyze collaborative governance in the implementation of the South Sumatera Movement for Independent Food Program in the South Sumatera Province. This research focuses on the management and utilization of assets of the General Bureau of South Sumatera Province, which is analyzed through the collaborative process adopted from the Ring and Van de Ven theory (1994). The collaboration process includes the negotiation process between the actors involved, the joint commitment to collaborate, the implementation of collaboration according to agreement, and the assessment of the entire collaborating process in the implementation of the South Sumatera Independent Food Movement Program in the ideal South Sumatera Province. Data collection techniques used include interviews, observations, and documentation. Data analysis techniques used interactive models, that is, condensation, data presentation, and conclusion drawings. The results of the research showed that the implementation of the GSMP in South Sumatera faced several obstacles in the field, among others—beneficiaries are still focused on the main activity of obtaining income, so the aid received has not been optimally utilized. The assistance provided has not been fully adapted to the field conditions and the skills of the beneficiaries at each location. Implementation of the South Sumatera Movement for Food Independence in the South Sumatera Province requires synergistic, coordinated, and collaborative cooperation between the actors involved – government, private/business, colleges, the public, and mass media.

Authors: Madani K.M. Isnaini
Published: May 2024

A regions success can be seen by the progress of city tourism, therefore tourism development, management, and development policies are needed that encourage concrete implementation. Thus, this research aims to evaluate the implementation of the tourism development program at Car Free Night Pedestrian Sudirman and Sekanak Lambidaro Palembang, using the context, input, process, product (CIPP) evaluation model analysis proposed by Stufflebeam and Chris LS Coryn [1]. This research used a qualitative method with the main instrument being in-depth interviews with 50 respondents. The results of observations showed that the implementation of the tourism development program was not going well, based on evaluation of performance expectations, social influence, facilitating conditions, improving the city’s economy, and interest in tourist visits. Thus, moving the location of the Car Free Night tourist destination from Pedestrian Sudirman to Sekanak Lambidaro Palembang did not have a significant role. This research suggests that Sapta Pesona should be actualized in increasing regional development through tourism which will benefit the community’s welfare.

Published: May 2024

The study of genetic resources using prolamin polymorphism in wheat cultivars from countries with different climatic conditions makes it possible to identify and trace the preference for the selection of the alleles of gliadine-coding loci characteristic of specific conditions. The aim of the study was to determine the “gliadin profile” of the collection of common wheat (Triticum aestivum L.) from breeding centers in Russia and Kazakhstan by studying the genetic diversity of allelic variants of gliadin-coding loci. Intrapopulation (μ ± Sμ) and genetic (H) diversity, the proportion of rare alleles (h ± Sh), identity criterion (I) and genetic similarity (r) of common wheat from eight breeding centers in Russia and Kazakhstan have been calculated. It has been ascertained that the samples of common wheat bred in Kostanay region (Karabalyk Agricultural Experimental Station, Kazakhstan) and Chelyabinsk region (Chelyabinsk Research Institute of Agriculture, Russia) had the highest intrapopulation diversity of gliadin alleles. The proportion of rare alleles (h) at Gli-B1 and Gli-D1 loci was the highest in the wheat cultivars bred by the Federal Center of Agriculture Research of the South-East Region (Saratov region, Russia), which is explained by a high frequency of occurrence of Gli-B1e (86 %) and Gli-D1a (89.9 %) alleles. Based on identity criterion (I), the studied samples of common wheat from different regions of Kazakhstan and Russia have differences in gliadincoding loci. The highest value of I = 619.0 was found when comparing wheat samples originated from Kostanay and Saratov regions, and the lowest I = 114.4, for wheat cultivars from Tyumen and Chelyabinsk regions. Some region-specific gliadin alleles in wheat samples have been identified. A combination of Gli-A1f, Gli-B1e and Gli-Da alleles has been identified in the majority of wheat samples from Kazakhstan and Russia. Alleles (Gli-A1f, Gli-A1i, Gli-A1m, Gli-A1o, Gli-B1e, Gli-D1a, Gli-D1f, Gli-A2q, Gli-B2o, and Gli-D2a) turned out to be characteristic and were found with varying frequency in wheat cultivars in eight regions of Russia and Kazakhstan. The highest intravarietal polymorphism (51.1 %) was observed in wheat cultivars bred in Omsk region (Russia) and the lowest (16.6 %), in Pavlodar region (Kazakhstan). On the basis of the allele frequencies, a “gliadin profile” of wheat from various regions and breeding institutions of Russia and Kazakhstan was compiled, which can be used for the selection of parent pairs in the breeding process, the control of cultivars during reproduction, as well as for assessing varietal purity.

The diversity of pathogenetic mechanisms underlying arterial hypertension leads to the necessity to devise a personalized approach to the diagnosis and treatment of the disease. Metabolomics is one of the promising methods for personalized medicine, as it provides a comprehensive understanding of the physiological processes occurring in the body. The metabolome is a set of low-molecular substances available for detection in a sample and representing intermediate and final products of cell metabolism. Changes in the content and ratio of metabolites in the sample mark the corresponding pathogenetic mechanisms by highlighting them, which is especially important for such a multifactorial disease as arterial hypertension. To identify metabolomic markers for hypertensive conditions of different origins, three forms of arterial hypertension (AH) were studied: rats with hereditary AH (ISIAH rat strain); rats with AH induced by L-NAME administration (a model of endothelial dysfunction with impaired NO production); rats with AH caused by the administration of deoxycorticosterone in combination with salt loading (hormone-dependent form – DOCAsalt AH). WAG rats were used as normotensive controls. 24-hour urine samples were collected from all animals and analyzed by quantitative NMR spectroscopy for metabolic profiling. Then, potential metabolomic markers for the studied forms of hypertensive conditions were identified using multivariate statistics. Analysis of the data obtained showed that hereditary stress-induced arterial hypertension in ISIAH rats was characterized by a decrease in the following urine metabolites: nicotinamide and 1-methylnicotinamide (markers of inflammatory processes), N- ace tyl glutamate (nitric oxide cycle), isobutyrate and methyl acetoacetate (gut microbiota). Pharmacologically induced forms of hypertension (the L-NAME and DOCA+NaCl groups) do not share metabolomic markers with hereditary AH. They are differentiated by N,N-dimethylglycine (both groups), choline (the L-NAME group) and 1-methylnicotinamide (the group of rats with DOCA-salt hypertension).

Published: May 2024

Relevance. With the restructuring of the economy in the carbon-neutral side, the negative anthropogenic impact can be weakened. It is very likely that there will be a comprehensive analysis of the impact of various climatic accidents in the country and its action to eliminate the risk of carbon dioxide. Moreover, studies in the experience of the peoples of the states make it possible to use their achievements in the field of climate policy in Russia, improve and modernize their advantages from the characteristics of the national economy. Aim. To assess the degree of influence of environmental, climatic and macroeconomic factors on the change in the carbon intensity of the economies of the world. Objects. The parameters of the climate policy of the countries of the world in the field of regulation of carbon dioxide emissions, the subject of the study is the relationship of environmental, climatic and macroeconomic factors with the carbon intensity of the economies of the world. Methods. Econometric method of panel data analysis. Scientific novelty. The paper confirms the hypothesis of the negative impact of one of the main climate policy instruments of the countries of the world (carbon prices) on the carbon intensity of the economy using the construction of the original panel data model. Results. The authors have substantiated a set of factors that affect the carbon intensity of the countries of the world, supplemented by such an indicator as the carbon price, which is one of the main indicators of climate policy development in the country. All factors were divided into two groups (macroeconomic and ecological-climatic) and a database was formed for 24 countries. Using the panel data method, the authors constructed the equation of the dependence of the carbon intensity of the economies of countries on macroeconomic and ecological and climatic factors. The authors tested the hypothesis of the carbon price negative impact on the carbon intensity of the economies of countries. Evaluation of various model specifications allowed us to confirm this hypothesis, which indicates the importance of the climate policy development within each country and the feasibility of introducing new tools to regulate carbon dioxide emissions. It was also determined that GDP, as a general indicator of the development of the entire economy, has the greatest impact on reducing carbon intensity. At the same time, in order to reduce the ratio of carbon dioxide emissions to gross domestic product, it is necessary to pursue a policy of replacing fossil fuels with low-carbon energy sources, but only taking into account the country raw material capabilities and the industry specifics of the economy.

The upcoming trends for state estimation methods development in the event of dynamic processes in power system areas are also formed.
Analysis of the Stability of the Tuberculosis Disease Spread Model
Authors: Wahyu Dewanti Retno
Published: May 2024

This paper discusses the stability analysis of the model for the spread of tuberculosis and the effects of treatment. The authors analyze the dynamic behavior of the model to investigate the local stability properties of the model equilibrium point. The Routh-Hurwitz criterion is used to analyze local stability at the disease-free equilibrium point, while the Transcritical Bifurcation theorem is used to investigate the local stability properties of the endemic equilibrium point. The results of the discussion show that the stability properties of the equilibrium point depend on the value of the basic reproduction number which is calculated based on the Next Generation Matrix (NGM). When the basic reproduction number value is less than one, then the disease-free equilibrium point is locally asymptotically stable, whereas if it is more than one, then the endemic equilibrium point is locally asymptotically stable. Numerical simulations are included to explain the dynamic behavior of disease spread and to understand the effectiveness of tuberculosis treatment in a given population. The simulation results show that treatment in the infected individual phase is known to be more effective than treatment in latent individuals.

Authors: Werdhani Retno Asti , Kusuma Dewi Dian , Findyartini Ardi , Ramlan Andi Ade , Sugiharto Agus
Published: May 2024

The Community Oriented Medical Education (COME) approach to medical education focuses on the population and individuals while covering all elements of health problem priorities. The World Health Organization (W.H.O) Strategic Framework identifies five key strategic directions for enhancing basic medical education to meet existing health concerns. A long-term, integrated module across disciplines is one strategy that the Faculty of Medicine at Universitas Indonesia has experienced in its implementation in both community and clinical medicine. The module includes a variety of field practices (hospital and primary care) as well as inter-departmental personnel (committees and tutors). The module has bridged the gap between community medicine and clinical medicine, with integrated staff as well as collaboration between the departments of community medicine and clinical medicine. Community medicine has been seen as important not only for epidemiological concerns but also as part of the clinical teaching approach that prepares students for careers in hospitals or primary care after graduation. COME can be taught in multidisciplinary or inter-departmental collaboration to accomplish applied learning outcomes for individuals and community health activities. COME ensures our education system produces medical graduates to meet health system needs with the help of faculties and teachers who are also responsible for community health and well-being.

Growth and development is a significant phase that cannot be replicated, underscoring the need for meticulous attention, particularly for those born with low birth weight (LBW). LBW can be stimulated using infant massage. This research aimed to evaluate the impact of infant massage on weight gain among LBW infants. This is a systematic review using PICOS framework, investigating studies from 2018 to 2023 in databases including Cochrane, PubMed, ScienceDirect, and Scopus. The inclusion criteria involved full-text access and the keywords low birth weight, weight gain, and massage. The initial search yielded 1913 literature, which were screened based on publication year and type, resulting in 122 articles. After being examined, 119 articles were excluded due to duplication, using non-English language, involving non-LBW, different outcomes, and non-RCT, leaving three articles. The assessment of literature quality was conducted using the JBI Critical Appraisal Checklist for Systematic Reviews and Research Syntheses. The results of outcome measurements and group comparisons across the three studies exhibited congruence. In conclusion, the finding indicated that infants who underwent massage intervention exhibited weight gain, as did those who did not undergo such intervention. Furthermore, infants who received massage intervention experienced a more pronounced increase in weight compared to their counterparts who did not undergo massage intervention.

Published: May 2024

Studies and opinion articles present unequal conclusions concerning empathy and morality, mainly because a somewhat heterogeneous and foggy conceptual approach prevails. This scoping review aims to analyse the relationship between empathy and morality and to present a novel conceptual model of empathy applied to moral decisions.A search in PsycINFO, Scopus and PubMed identified articles addressing the relationship between empathy and morality.Thirty-two articles were included. We find an absence of a consensual definition of empathy. It is commonly defined as a predominant emotional process and a factor of bias and prejudice in moral decisions.According to our conceptual model, empathy is a distinct, complex human neuropsychological capacity that mobilises and is dependent on the proper functioning of several brain areas and balances the scales on which are Emotion and Reason, enabling the most thoughtful moral decisions possible in diverse circumstances and contexts.
Preparation and Characterization of Superabsorbent Polymers (SAPs) Based on PUL-g- AM/AA by Microwave Irradiation
Authors: Dhahir Salam Abdulla , Braihi Auda Jabbar , Habeeb Salih Abbas
Published: May 2024

A microwave technique prepared a superabsorbent polymer (SAP) by grafting two hydrophilic monomers onto a polysaccharide substrate. The monomers used are acrylic acid (AA) or acrylamide (AM) to graft onto a pullulan substrate (PUL) to form PUL-g- AA (SAP1) and PUL-g- AM (SAP2), respectively. The monomers (AM/AA) graft together onto a PUL substrate to form PUL-g-(AM/AA) (SAP3). Grafting parameters such as grafting efficiency with percentage, conversion of monomer to polymer, gel content, water retention, water adsorption capacity, and swelling kinetics were determined. Additionally, the effect of environmental pH (2, 4, 7, 9, and 12) and sodium dodecylbenzene sulfonate (SDBS) surfactant was evaluated, where SDBS was added by 1,2,3,4 and 5 mM to form (SAP4 to SAP8). FTIR results show that AM grafted on PUL through an aliphatic C-N bond, while AA grafting occurred through a single C-C bond. The grafting efficiency with AM is higher than with AA, as well as their gel contents. Water absorbance capacity increased with grafting of AA or AM separately, and water retention was enhanced. The highest absorbent capacity, water retention, gel content, and grafting parameters values were obtained with 3 mM SDBS content and pH7. The swelling kinetics showed that the increases in the theoretical and experimental swelling equilibriums were 72 % and 82%, respectively, at SAP6 compared to the values of these parameters in SAP3. The water absorption capacity of the hydrogel increases with increasing pH to 7 and then gradually decreases. XRD improves the crystallinity and crystalline size of the hydrogel after grafting polymerization for AM/AA into PUL, in addition to enhancing thermal stability. On the contrary, FE-SEM demonstrated that SDBS improves the porosity and pore size of the hydrogel surface in SAP6.
Comparative Study of Rheological Properties of Fly Ash-Based Geopolymer Reinforced With PP Fiber For 3D Printing: An Experimental and Numerical Approach

Published: May 2024

The present study drops the line for the flow characteristics of fly ash-based (FA) geopolymers reinforced with polypropylene (PP) fibers undergoing the extrusion process during three-dimensional printing. Applying to the Herschel-Bulkley rheological model the research is ready with the sound theoretical basis which is used to understand the flow behavior of these materials under various conditions. A combination of experimental and numerical techniques that are based on the Finite Element Method (FEM) in COMSOL has been used in this study. The results of both the experimental and simulation approaches are then compared and the behavior of the material during extrusion is then examined. The experimental results proved PP fiber content has significant effects on rheological properties. The experiments on mixes which are either devoid of fibers or possess a high content of fiber, encountered problems like a high static yield stress and material segregation. Mixes with fibers of moderate content showed smoother extrusion processes, which means that a suitable range of fiber addition exists for the fibers that optimally balance the mechanical properties and extrudability. Numerical simulations typically agreed with experimental data for fiber contents up until it reached a certain level but not above, suggesting the existence of more complex interactions inside the fibers and the necessity for the subsequent model refinements. The investigation outlines a 0.25% and 0.5% fiber content range that leads to enhanced performance without bringing the extrusion process to greater complications and further making the production of proper, architecturally printed structures possible.

Expression of the breast cancer resistance protein (BCRP/ ABCG2) transporter is downregulated in placentas from women with preeclampsia (PE) and in an immunological rat model of PE, which closely resembles human PE. While many drugs are substrates of this important efflux transporter, the impact of BCRP downregulation on maternal and fetal drug exposure has not been investigated. Using the PE rat model, we performed a pharmacokinetic study with rosuvastatin (RSV), a BCRP substrate, to investigate this impact. PE was induced in rats during gestational days (GD) 13 to 16 with daily low-dose endotoxin. On GD18, RSV (3 mg/kg) was administrated intravenously, and rats were sacrificed at time intervals between 0.5-6 hours. Placental expression of Bcrp and Oatp2b1 significantly decreased in PE rats. A corresponding increase in RSV levels was seen in fetal tissues and amniotic fluid of the PE group (p<0.05), while maternal plasma concentrations remained unchanged. An increase in Bcrp expression and decreased RSV concentration, was seen in the livers of PE dams. This suggests that PE-mediated transporter dysregulation leads to significant changes in the maternal and fetal RSV disposition. Overall, our findings demonstrate that altered placental expression of transporters in PE can increase fetal accumulation of their substrates.

Developing and utilising of underground space is an vital direction for urban growth. Underground commercial streets, as a significant component of underground space accommodating extensive human social activities, and consequently necessitate the creation of human-scale spaces. In the evolution of urban design development towards greater refinement, applying architectural theories and excessively subjective designs has resulted in a deficiency of human-centered design and a disordered spatial environment. This study merges environmental psychology and architectural theory to determine the appropriate length of spatial scale. Two experiments focusing on spatial perception evaluation were conducted using a virtual experimental platform that featured varying dimensions of spatial scale combinations. These quantified combinations were correlated with perception evaluation, and regression analysis was employed to identify appropriate scale ranges, which were superimposed on the range of length selection. Finally, the optimal length and scale combination for underground commercial street spaces were established, providing a reference for the human-centered design of these environments.

: Cytokine storm is usually described as one of the main reasons behind COVID-associated mor-tality. Cytokines are essential protein molecules engaged in immune responses; they play a critical role in protection against infections. However, they also contribute to inflammatory reactions and tissue damage, becoming a double-edged sword in the context of COVID-19. Recent studies have suggested various cytokines and chemokines that play a crucial role in the immune response to SARS-CoV-2 infection. One such cytokine is Interleukin 27 (IL-27), which has been found to be elevated in the blood plasma of patients with COVID-19. Within this study, we will explore the role of IL-27 in immune responses and address our own findings concerning this cytokine in COVID-19. It affects a wide variety of immune cells; regardless of the pathological process it is involved in, IL-27 is critical for upholding the necessary balance between tissue damage and cytotoxicity against in-fectious agents and/or tumors. In COVID-19, it is involved in multiple processes, including antiviral cytotoxicity via CD8+ cells, IgG subclass switching, and even the activation of Tregs.

Metocean data of a certain region can assist in determining the design criteria of offshore or nearshore infrastructures which can prevent structural failure and even overdesigning. The common method of using met ocean data to forecast the wave and climatic conditions of a coastal region is by utilizing the hindcast approach. In collaboration with a project that plans to design a nearshore structure for seaweed cultivation, this study focuses on the collection and analysis of met ocean data of potential sites in Malaysia to prevent under-designing and over-designing of the structure. The study and analysis of met ocean data are essential in predicting future environmental conditions. The study investigates the met ocean environment for the spatial design and monitoring of a seaweed aquaculture farm at the following potential sites; Western Coast near Langsuir Cave, Pulau Langkawi, Eastern Coast near Bachok, Kelantan, Eastern Coast near Setiu Wetland or River, Terengganu, Western Coast near Bidong Island, Terengganu.
