Authors: LOH SAW HONG , ANUAR NUR SYAMIMI , MOHAMED ZUKI HAFIZA , WAN MOHD KHALIK WAN MOHD AFIQ
Published: June 2024

Polycyclic aromatic hydrocarbons and endocrine-disrupting phenols are both ubiquitous pollutants in the environment. Human activities through urbanisation and rapid industrialisation are at the forefront of global environmental pollution. Therefore, removing pollutants in miscellaneous characteristics is important to eliminate the stage-by-stage reduction of pollutants, especially from wastewater, for a cost-effective and time-effective treatment. A simple preliminary study was conducted for the concurrent removal of acidic 2, 4, 6-trichlorophenol (2, 4, 6-TCP) and neutral fluorene (FLU) from water by mixed-mode resins that consist of Anion Exchange Chromatography (AEC) and reversed-phase C18 sorbents. The one-variable-at-time approach was applied in the optimisation of the removal process, where sorbent dosage, exposing time, stirring speed, and sample pH were investigated to enhance the removal efficiency. Under the optimal conditions, 20 mg of each AEC and C18 successfully removed 74.8% of 2, 4, 6-TCP and 96.5% of FLU from the water sample spiked with 50 mg/L of 2, 4, 6-TCP and 0.5 mg/L of FLU that was pre-modified to pH 9 and agitated at 600 rpm for 10 min. The AEC and C18 achieved a removal capacity of 37.4 mg/g for 2, 4, 6-TCP and 0.48 mg/g for FLU, respectively, upon treating 20 mL of the water sample. The mixed-mode resins combine the capabilities of two different retention mechanisms and allow for the simultaneous removal of a broad range of compounds from environmental samples.

Published: June 2024

Usaha Kecil dan Menengah (UKM) Indonesia berada dalam paradoks kontribusi pertumbuhan ekonomi dan implikasi negatif lingkungan hidup yang masif. Pemilik bisnis didorong bertransformasi menjalankan bisnis dengan mengedepankan keberlanjutan lingkungan hidup dan sosial kemasyarakatan. Konsep green knowledge economy mendorong seluruh sektor mengembangkan pengetahuan untuk meningkatkan kualitas hidup masyarakat dan ekologi melalui kapabilitas bisnis. Namun selama ini konsep green knowledge economy hanya ditekankan pada sektor skala besar. Sehingga studi ini bertujuan untuk mengkaji pengaruh green knowledge economy terhadap kinerja bisnis UKM berbasis SDGs, dengan fokus khusus pada potensi manfaat dan tantangan yang terkait dengan fenomena ini. Lima dimensi green knowledge economy (green industry 4.0 technologies, green education-HRM, circular economy practices, green economic incentives-institutional system, and green innovation) diusulkan terhubung dengan dimensi SMEs sustainable development dengan 20 usulan hipotesis. Studi ini memilih pendekatan kuantitatif dengan melaksanakan survei yang melibatkan 337 pemilik UKM Indonesia dengan teknik penarikan purposive sampling. Data yang didapatkan dianalisis dengan teknik pemodelan Structural Equation Modelling-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan hipotesis yang menghubungkan Green Industry 4.0 Technologies, Green Education and HRM, Circular Economy Practices, Green Economic Incentives and Institutional System, serta Green Innovation, Research and Development dengan dimensi keberlanjutan (Ecological, Institutional, Socioeconomic, dan Community Sustainable) secara signifikan diterima, kecuali pengaruh praktik ekonomi sirkular yang tidak mempengaruhi institutional sustainable. Dalam mencapai kontribusi keberlanjutan UKM maksimal, diperlukan strategi kebijakan pemerintah yang mendukung UKM bertransformasi berkelanjutan dengan peningkatan kapabilitas pengetahuan ekonomi hijau. Kolaborasi riset penopang transformasi dibutuhkan dalam mendukung pengembangan praktik bisnis yang berkelanjutan dan inovatif di kalangan UKM. Penting untuk mengintegrasikan konsep green knowledge economy ke dalam program pelatihan, pendidikan, dan bantuan keuangan yang disediakan bagi UKM guna memastikan kesinambungan ekonomi yang berdampak positif secara sosial dan lingkungan.
Assessment and Scalability
Authors: Price Anne , Savoie Michael
Published: June 2024

The concept and practice of experiential education is rapidly expanding as universities seek to strengthen and integrate high-impact practices under experiential education plans and centers. While this integration has the potential to create synergy across disparate experiential learning offerings and to provide the benefits of experiential learning to all enrolled students, across majors and modality, scalability and assessment present a challenge. Many experiential learning practices were designed to serve a subset of enrolled students, and are resource-intensive in terms of faculty development and content delivery, assessment, and financial resources required. This paper presents the development and in-progress refinement of a experiential learning program at a regional comprehensive university in the southeast. The goal is to provide a detailed description of one EL program at one particular type of university, in order to add heterogeneity to the options university leaders can use as models. In addition, while this program has faced stumbling blocks, we believe it presents a strong template for other EL programs, with particular strength in comprehensive assessment.

Published: June 2024

This paper explores the dualistic nature of experiential learning (EL) definitions in higher education, advocating for a balanced integration of broad and narrow constructs. Through case study and collaborative inquiry, diverse disciplinary perspectives—from engineering to performing arts and urban education—are examined to understand EL's application and impact. The paper highlights the importance of accommodating both overarching frameworks for universal applicability and specific definitions for disciplinary depth. It proposes that broad definitions enhance inclusivity and adaptability, while narrow constructs ensure targeted learning experiences and skill development. The findings suggest that EL is a versatile pedagogical tool. It is adaptable to varied academic landscapes and yet maintains its essence of active, reflective engagement with the world. Finally, the paper argues that both the broad and narrow definitions are necessary to ensure EL remains a transformative educational pedagogy.

Published: June 2024

This study modelled the slump of concrete containing crushed glass and Bida Natural Gravel (BNG) based on deep learning algorithm using the MATLAB neural network toolbox. A total of 240 (150mm × 150mm × 150mm) cubes were cast from 80 mixes generated randomly using Scheffe’s simplex lattice approach. Slump was measured for each of the experimental points of fresh concrete before filling in the moulds. The resulting batch for each mix was used as input data while the laboratory results for slump was used as output data for the ANN-model. Hence a shallow multilayer supervised Neural Network was developed to model these data. The developed model would be able to predict concrete slump containing 0% - 25% crushed glass as partial replacement for fine aggregate, water- cement ratio ranging from 0.45 – 0.65 and concrete grade M15 – M25. The architecture of the network contained 6 input parameters: water to cement ratio, water, cement, sand, crushed glass and BNG, 20 neurons in the hidden layer and slump in the outer layer. The adequacy of the developed model was measured using Mean Square Error (MSE) and Correlation Coefficient (R). Results showed that 6:20:1 model architecture for slump model had an MSE values for training, validation and testing as: 1.84e-2, 5.81e-3, 3.64e-3, 1.73e-3 respectively. Regression values for training, validation and testing are: 79%, 94%, 96% and 79%. The study concluded that a shallow multilayer Neural Network architecture with 20 neurons in the hidden layer is sufficient for predicting concrete slump.

Published: June 2024

This study examines the structural, electrical, magnetic, and magnetocaloric properties of La0.8Ag0.2Mn0.9A0.1O3 (A: Mn, and Co) compounds under doping in the B-site. XRD results show that the compound containing Co ions directly replaced Mn ions in the B-site without forming a secondary phase containing higher metallic Ag impurities. The data obtained using Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), the temperature dependence of magnetization (M-T), the magnetic field dependence of magnetization (M-H), and the magnetic entropy change (SM) analysis reveal the effect of the doped element on the magnetic properties of the compounds due to the changes they create in the structural and Mn3+/Mn4+ ratio. It has been determined that the paramagnetic to ferromagnetic transition temperature (Curie temperature, TC) of the La0.8Ag0.2Mn0.9Co0.1O3 (LAMO-Co) is quite lower than the LAMO.

Published: June 2024

As a huge maritime country, Indonesia has tremendous potential for marine resources. Indonesia is the largest tropical marine country in the world and has the largest biodiversity in the sea. The potential of marine biological resources in Indonesian waters has always been able to provide optimal benefits for the economic and socio-cultural development of the community. However, many fishermen conduct fishing easily and destructively (destructively fishing) of marine ecosystems using fishing gear that is not environmentally friendly to meet the demand for fish needs. The perpetrators use Dupont Lannate chemicals containing Methomil with mashed fish and then spread it into the sea, then pick up the dead fish. The use of chemical poisons can kill the animals that make up the coral so that the coral becomes discolored which eventually dies and other fish that are not targeted also die. Therefore in this study, the author examines law enforcement in Indonesia’s marine territory to protect the biodiversity of Indonesia’s marine areas. this study uses a Normative research type that examines national and international legal arrangements regarding the protection of the marine environment. Therefore researchers examine the regulation and effectiveness of law enforcement in Indonesia.

Published: June 2024

Despite of Indonesia’s vast solar energy potential according to the Indonesian Ministry of Energy and Mineral Resources, Indonesia’s total installed capacity of rooftop solar photovoltaic (PV) is very far from Indonesia’s target of 3.6 GW in 2025. Indonesia once applied net metering scheme for rooftop solar PV policy and was expected to be able to boost rooftop solar PV growth. A system dynamics approach is used in the research to develop an assessment model to evaluate the policies’ impact on residential rooftop solar PV system growth. A Causal Loop Diagram was established then transformed into Stock and Flow Diagram (SFD) using software Vensim PLE 10.1.3, which was used to simulate several policies’ scenarios related to residential rooftop solar PV adoption and CO2 emissions reduction. Ten scenarios were simulated in this study involving three groups of intervention: initial net metering tariff, reduction on initial solar PV cost, upper limit of ROI, and combination of initial net metering tariff and initial solar PV cost reduction. The simulations revealed that combination of increasing net metering tariff to 80% & initial cost reduction 30% has the highest potential solar PV installations, the highest CO2 emissions reduction, and the lowest accumulation cost of net metering in 2030. This study can be used as reference by the policy makers in Indonesia to formulate the optimum policy to boost rooftop solar PV growth as the simulations shows that residential rooftop solar PV with the right intervention can meet the government’s target of rooftop solar PV in 2030.

Evaluating temperature variation of nutrient solution in Nutrient Film Technique (NFT) cooling system for temperate vegetable
Authors: Fazlil Ilahi Wan Fazilah , Rosdi Nur Syaffiqa Izleen , Ahmad Tajri Azmi
Published: June 2024

The production of leafy green vegetables in hydroponic systems within greenhouses has gained global prominence in the fresh vegetable production industry. Hydroponic systems, particularly Nutrient Film Technique (NFT), are highly effective due to their soilless nature and efficient nutrient and water circulation. However, maintaining ideal greenhouse temperatures can be challenging. One strategy to reduce energy costs is to heat or cool the nutrient solution instead of the entire greenhouse environment. By regulating the root zone temperature through nutrient solution management, growers can provide more favourable conditions for temperate leafy greens. These conditions are critical because temperatures above 23°C can inhibit plant growth, while temperatures exceeding 35°C can significantly reduce plant metabolism efficiency. This study investigates how lettuce responds to nutrient solution cooling. Importantly, this research focuses on Malaysia, an equatorial country with a consistently warm and humid climate. In such environments, controlling nutrient solution or air temperature to match the crops' optimal growth requirements is crucial. The study employed Butterhead and Romaine lettuce varieties in a hydroponic NFT system. The EC (Environmental Cooling) treatment involved cooling the nutrient solution, while the RZC (Root Zone Cooling) treatment utilized environmental cooling. The results demonstrated that maintaining a consistent nutrient solution temperature within the range of 14°C to 18°C (as observed in the EC treatment) led to superior plant growth and quality, particularly in the early growth stages. In contrast, the RZC treatment showed temperature fluctuations, causing plant stress and inhibiting growth.
Organized (Exchange) Trading and Price Indicators as Instruments of Effective Commodity Markets, Public Policy and International Cooperation
Authors: Golomolzin A. N.
Published: June 2024

Approaches to the assessment of objective price indicators are described. It is said that price antimonopoly control has various forms, but it cannot turn into price regulation. Antimonopoly price control is based on the comparison of price characteristics and conditions of comparable markets. Indicators of organized (exchange) trading can become one of the most representative indicators of the level of market prices. It is important not to limit yourself to stock quotes, but also to use over-the-counter price indicators and price indicators of comparable foreign markets. It is shown that the whole set in the "price triangle" should be applied based on the condition of their methodological comparability. It is noted that the relevant price indicators at the national level, within the framework of the EAEU and the CIS, within the framework of BRICS+ make it possible to qualitatively improve the terms of trade on national and international markets.

Chronic Hematological alterations in COVID-19 patients range from mild to severe, with common changes including lymphopenia, neutrophilia, and thrombocytopenia. The gold standard for diagnosis is the polymerase chain reaction (PCR) test, which is highly specific and sensitive for detecting SARS-CoV-2 genetic material. The study was a single isolation center retrospective analysis of 200 patients with COVID-19 confirmed cases. The hematological indicators were taken after sample blood collected from the staff of Central Public Health Laboratory to determine the changes, and compared between different grades of severity and prognosis with the hematological indicators. The data was analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0. simple frequencies and percentage were used, while chi-square test used to determine the association between variables. Males consisted 73.5% in this study, while 63% of participants suffered from moderate severity. Related to the hematological changes; and comparisons made according to real-time PCR test results revealed that the Lymphocytopenia and leukocytosis presented among 47.5% and 46.5% respectively with significance association with illness severity and outcome of patients with p-value< 0.05. hematological changes in COVID-19 patients are a common and significant aspect of the disease. Lymphopenia, neutrophilia, thrombocytopenia, and increased levels of inflammatory markers are frequently observed. These hematological abnormalities are associated with disease severity, poor clinical outcomes. Blood parameters aid in COVID-19 diagnosis and prognosis, with abnormal hematological parameters providing early evidence. However, interpretation should consider limitations, sample size, and potential biases. Further research needed.

Aim. Biopharmaceutical assessment of various solid dosage forms (capsules and coated tablets) of febuxostat formulations including comparison of excipients used in these dosage forms, disintegration pathways under static conditions, and dissolution kinetic profiles. Methods. The Azurix® coated tablets and Podagrel hard gelatin capsules containing 80 mg of febuxostat were the object of the study. The model of disintegration under static conditions was used to assess disintegration of the dosage forms. Quantification of febuxostat in the samples diring the comparative study of dissolution kinetics was performed by high-performance liquid chromatography. Results. When assessing morphological changes of dosage forms in the static model developed to simulate gastric environment, various desintegration patterns and rates confirmed by the differences in the qualitative composition of the excipients used were defined for these dosage forms. The comparative kinetics study showed different rates of febuxostat release from the studied dosage forms. Conclusion. The findings demonstrate a significant impact of the excipient composition on the behavior of dosage forms in the body environment, particularly on the dosage form desintegration, which in turn defines the rate and degree of the active ingredient release. Thus, the test shows pronounced differences in biopharmaceutical parameters, capable of affecting the studied drugs bioavailability, between two febuxostat dosage forms.
Clinical case: acute on chronic liver failure (ACLF)

Acute-on-chronic liver failure (AcLF) is an acute liver disorder manifested as jaundice (serum bilirubin levels ≥5 mg/dL) and coagulopathy (Inr ≥1.5 or prothrombin activity < 40%), complicated by ascites and/or encephalopathy within 4 weeks, that is found in patients with the previously diagnosed or undiagnosed chronic liver disease. AcLF is a serious medical issue worldwide. The AcLF pathogenesis is based on the pronounced systemic inflammatory response to pathogenic antigens and biological structures produced during the liver cell death, with subsequent immune paralysis and multiple organ failure. Acute-on-chronic liver failure (AcLF) may develop at any stage, from compensated to decompensated cir- rhosis; the disorder may involve both hepatic and extrahepatic precipitating events. drug treatment of AcLF includes early detection and treat-ment of the precipitating factor and maintenance therapy. It has been proven that treatment of the trigger at an early stage reduces mortality,however, the management of AcLF is focused mostly on the maintenance therapy. AcLF belongs to the syndromes seldom diagnosed in clinical practice, that is why the AcLF case study is of special interest. The paper reports a confirmed case of AcLF.

Features of the clinical case: an elderly patient was not vaccinated against COVID-19, suffered from hypertension and obesity for a long time, was hospitalized with COVID-19, complicated by community-acquired pneumonia of moderate severity. Subsequently, atrial fibrillation developed, which could not be eliminated. Long-COVID risk factors: female gender, polymorbid background, elevated C-reactive protein levels, neutrophilosis and lymphopenia occurred in the presented clinical case.
Laboratory diagnosis of pancreatic diseases
Authors:   Kemerovo State Medical University
Published: July 2024

Diseases of the pancreas in diagnosis are very problematic, since the symptoms are non-specific, and the training of doctors in the field of clinical pancreatology leaves much to be desired. With a incidence of 3–4/100 000 inhabitants and a prevalence of 10–40/100 000 inhabitants, chronic pancreatitis is a relatively common disease in industrialized countries. In our practice, we often encounter overdiagnosis of this pathology. CP represents the end of the continuum of diseases between acute and chronic pancreatitis. This article is intended to cover the basics of laboratory diagnostics of chronic pancreatitis and at the same time point to open questions for clinical research, expand the horizons of doctors, to timely determine both inflammatory processes in the pancreas and its exo- and endocrine insufficiency to prescribe adequate treatment.

Extramammary Paget's disease (EMPD) is a rare variant of adenocarcinoma, the most common localization of which is a vulva. Clinical manifestations are nonspecific and can be initially diagnosed as manifestations of other dermatoses, which makes early diagnosis difficult. The most effective diagnostic method is a pathomorphological and immunohistochemical examination of the skin biopsy. We present a clinical case of EMPD in a 42-year-old HIV-infected female patient.
