Published: May 2024

Islamic Religious Education (PAI) has great potential to increase understanding and application of religious values that are in line with local wisdom. However, existing learning modules often do not integrate these two aspects explicitly, resulting in a gap between theory and practice. This research aims to develop a PAI learning module based on local wisdom and assess its effectiveness in increasing student understanding and engagement.This research uses literature research methods, by collecting and analyzing sources relevant to the development of PAI modules and local wisdom. The research results show that learning that integrates PAI with local wisdom not only enriches students' religious knowledge but also increases their understanding of the application of these values in their social and cultural context. The module developed successfully integrates examples of local wisdom that are relevant to PAI subject matter. Initial assessments show positive responses from students as well as increased interest and participation in the learning process.

Published: May 2024

This research aims to analyze the influence of service quality on customer satisfaction, the influence of insurance costs on customer satisfaction and the size of installments on customer satisfaction for multi-purpose financing at the Sumut Syariah Bank, Padangsidimpuan Branch. This research uses primary data by distributing questionnaires to multi-purpose financing customers. The population of this research is all multi-purpose financing customers with a total of 862 people. The sample used in this research was 90 respondents. The validity test uses the Pearson Product Moment correlation test, while the reliability test uses Cronbach alpha. Classic assumption tests include normality tests, multicollinearity tests, heteroscedasticity tests and autocorrelation tests. Hypothesis testing in this study used multiple linear regression analysis. The research results state that service quality and insurance costs partially have a positive and significant effect on customer satisfaction. This means that the higher the quality of service provided will increase customer satisfaction, and the suitability of the insurance costs provided with the benefits obtained by the customer will provide a level of customer satisfaction. Meanwhile, the installment amount does not have a significant effect on customer satisfaction, this is because previously the installment amount had been analyzed using scoring analysis which had an influence on the installment amount.

Authors: Fasmalia Putri , Angela Deni
Published: May 2024

The issue of environmental permits for PLTU Tanjung Jati A is a serious problem because the publication does not include an analysis of the release of CO2 emissions which have an impact on environmental damage and climate change. This research aims to describe Walhi West Java's strategy in its efforts to cancel the environmental permit for PLTU Tanjung Jati A through its international and national networks. In line with this aim, this research uses a case study approach with data collection carried out through in-depth interviews and analysis of related documents. The theory used by the Transnational Advocacy Network (TAN) theory as an analytical tool was put forward by Margaret E. Keck and Kathryn Sikkink. The results of this research, Walhi West Java has implemented four TAN strategies, namely Information Politics by disseminating information and findings, Symbolic Politics by carrying out campaign actions with symbols, Leverage Politics by collaborating with stronger actors, and Accountability Politics by supervising actors who advocated to walk with the commitments that have been set. Based on these four strategies, Walhi West Java is very optimal in carrying out Information Politics and Leverage Politics strategies. The weakness is that the Political Accountability strategy has not been fully successful because the Tanjung Jati A PLTU project is still in the policy documents and RUPTL. Walhi West Java's TAN implementation strategy succeeded in bringing victory over the Head of DPMTSP regarding the cancellation of environmental permits.

Published: May 2024

A splicing system is a formal characterization of the ability to generate certain enzymatic activities acting on deoxyribonucleic acid (DNA) molecules. In this paper, the results from Laun’s experiment are used in characterizing the type of splicing languages. In the experiments, two initial strings are involved with different features on the selected restriction enzymes. Case I and Case II discussed in this paper show that the splicing languages obtained from these experiments are in adult and limit languages. Nevertheless, the result obtained in this paper is more precise in showing the type of splicing languages which is beyond adult and limit languages when presented via a directed splicing graph. The features of the restriction enzyme that affect the formation of active persistent language are investigated based on the results proposed by Yusof.
Enhanced Segmentation of Ischemic Stroke Lesion in MRI Images Using a Geometrically Customised Deep Convolution Model (GCDCM)
Authors: Bhuvana R  , Hemalatha R.J.
Published: May 2024

Ischemic stroke lesion often known as a stroke, is a significant health issue that requires accurate analysis and classification of brain magnetic resonance imaging (MRI) data. In this study, we propose a novel deep transfer learning approach, called geometrically customized deep convolution model, for the purpose of MRI analysis and classification of brain stroke. Neurostroke segmentation is a serious medical image processing challenge. Segmented regions aid disease identification and treatment. Anywhere can form thrombi. Segmentation facilitates automatic detection because they can be any size or shape. Popular image analysis tool MRI diagnoses well. This diagnostic method shows brain stroke architecture. MRI must replace manual detection. Online datasets recommended cerebral stroke detection and segmentation. Deep learning model MRI scans and detectron 2 with masked CNN Nets segment thrombus. This net architecture recognises dataset stroke boundaries. Classifying strokes with vgg16, resnet50, inceptionv3, and resnet5 transfer learning is possible. Mask the image, then binary predict by eliminating the skull, extracting features, and iterating to find stroke. The model and thrombus mask are predicted if the binary prediction matches the human forecast. Otherwise, data processing resumes. Binary prediction uses the segmentation region and pixels overlap between the ground truth and predicted segmentation to calculate parameters. Compared to reality, the categorization of medical images with weak signals seems tough, especially with a short "train" dataset. Mixing deep learning architectures avoids these drawbacks and extracts signals to accurately classify classes. Deep neural networks best recognise, find, and divide computer vision objects for clinical image analysis. Preprocessing MRI scans, skull stripping with deep CNN architecture combinational net, and brain stroke segmentation are our main tasks. Modern medical image processing is hard. Flexible and uneven borders make brain strokes hard to identify and segment. The transfer learning-based super pixel approach segments brainstrokes. Because we predict every visual pixel, dense prediction occurs. Early discovery of thrombus improves treatment and survival. These procedures have considerably improved our quality indexes.

Published: May 2024

Cocos nucifera L. (family Arecaceae) commonly known as coconut is considered as an important fruit crop in tropical countries and are widely used for therapeutic and domestic purpose. They have effective properties such as antioxidant, antitumor, antiseptic and antimicrobial. The growing demand for green coconut water consumption and food industries cause the dumping of the shell and husk of this fruit, generating large amount of solid waste. This study utilized part of coconut waste to study the impacts of solvent type on the phenolic content. Six different polarities of solvent were chosen. Total phenolic content was performed using Folin-Ciocalteu assay and free radical scavenging activity with 2,2-diphenyl-1-picrilhydrazil (DPPH) method. Total phenolic content for coconut shell was the highest at 71.57 ± 0.275 mg GAE/g for propanol extract and 74.10 ± 0.741 mg GAE/g for acetone extract of coconut husk. The antioxidant activity of all sample extracts was analysed using DPPH assay. Highest radical scavenging activity of coconut husk was observed by propanol extract with 93.82 ± 0.052 % while the lowest scavenging activity was demonstrated by chloroform extract with percentage of 57.77 ± 2.255%. Acetone extract of the shell exhibited the highest scavenging activity of 91.23 ± 0.073%, while chloroform extract of coconut shell demonstrated the lowest antioxidant activity of 70.627 ± 0.467%.

Published: May 2024

This study investigates the energy conversion process of biomass into solid fuel, focusing on hydrothermal carbonization as the chosen method. The aim of study is to produce char with a higher energy yield compared to conventional combustion and pyrolysis methods. By manipulating the holding time in the hydrothermal process, this research examines the energy yields and their relationship with the storage and release of energy, thus impacting the heating values of the resulting char. The study establishes the optimal processing time critical for energy savings in hydrothermal energy conversion. Using mahogany wood as the initial biomass at a pressure of 5 atm and T = 200°C, the experiment involved a 200 g biomass with a 1:4 biomass to water ratio. The holding times varied at intervals of 30, 60, 90, and 120 minutes, respectively. The results indicate a direct proportionality between energy yields and heating values. The highest heating value of char, recorded at 5560.9088 kcal/kg, was achieved at a holding time of 60 minutes, while the lowest value, 2911.501 kcal/kg, was observed at 30 minutes. This suggests that a 60-minute duration in the carbonization process yields maximum energy output. Proximate analysis further supports this, indicating elevated levels of fixed carbon and volatile matter in the hydrothermal process. Then, the comparative analysis demonstrates that the heating value of the char exceeds that of char produced by pyrolysis and even surpasses raw mahogany wood. This study highlights the efficiency of a 60-minute hydrothermal carbonization process in maximizing energy yield, emphasizing its potential in biomass energy conversion.

Published: May 2024

Beach resorts located in coastal areas are particularly vulnerable to natural disasters and extreme weather events. Climate change exacerbates these risks, with rising sea levels, intense rainfall, and cyclones impacting coastal communities, including hotel operators. This study aims to address the challenge of tropical storms resulting from climate change in Langkawi's coastline region, specifically focusing on mitigating their impact on pedestrian wind comfort. The research investigates the quantitative impact of vegetative windbreaks on wind velocity at an open-building resort in Cenang, Langkawi, Malaysia. The goal is to propose effective strategies for reducing wind velocity and enhancing pedestrian wind comfort for beachfront resorts. The primary objective is to determine the optimal arrangement of vegetative windbreaks that provide optimal wind comfort for buildings. Numerical simulations were conducted to analyze flow characteristics around tree windbreaks, with validation through wind tunnel experiments. The simulation method, employing the RNG k-ε turbulence closure scheme, accurately predicted airflow patterns for both single and double rows of trees, treating the trees as porous media with defined aerodynamic properties. Results indicate that staggered double rows of windbreaks offer the most significant improvement in wind shelter, with a maximum mean Boundary Effectiveness Index (mBEI) of approximately 1.92. This configuration ensures greater downwind shelter distances compared to linear double rows and single-row windbreaks, thus enhancing wind comfort. Enhanced wind comfort is crucial for promoting safety and enjoyment during outdoor activities at resort facilities. Strategically planting windbreak trees enables resort management to create a more pleasant environment for guests, shielding them from strong winds while preserving aesthetic appeal. This study offers practical guidelines for resort developers, emphasizing optimal row arrangements and windbreak designs that balance environmental aesthetics with pedestrian wind comfort. Implementing these practices enhances the overall experience for resort guests, contributing to a safer and more enjoyable leisure environment.

The palm oil industry plays a vital role in Malaysia, but it generates substantial amounts of biomass waste, which, if not properly managed, can lead to environmental pollution. Among these waste products, oil palm empty fruit bunch (OPEFB) is the most abundant and underutilized, being generated daily without any commercial value. The aim is to efficiently convert OPEFB into fermentable sugars for improved biogas production. Nevertheless, the challenge lies in efficiently degrading OPEFB within a short timeframe before fermentation into biogas can occur. This study aims to explore the potential of hydrothermal pre-treatment as a means to enhance biogas production from OPEFB. The pre-treatment process was optimized by varying reaction temperatures (100 to 250°C), and reaction times (10 to 40 minutes). The main objective was to maximize the total soluble sugar yield, a crucial precursor for efficient biogas production. The optimal conditions for hydrothermal pre-treatment are identified at a temperature of 175°C and a reaction time of 20 minutes, resulting in a yield of 49.2 mg of glucose per gram of OPEFB. Subsequent anaerobic co-digestion of the treated OPEFB with digested sludge increased methane yield to 100.53 ml/g-VS, representing a remarkable 392% increase compared to the low 20.44 ml/g-VS produced by untreated OPEFB. Nonetheless, elevated pre-treatment temperatures (200°C and above) led to reduced biogas production due to inhibitory compounds. This study demonstrates the effectiveness of hydrothermal pre-treatment as a low-temperature, green technology for enhancing OPEFB-based biogas production, contributing to Malaysia's renewable energy goals. Future research should focus on scale-up and validation of this integrated process.

Published: May 2024

Terminal synergetic control (TSC) is proposed as a control strategy for the temperature management of a plate heat exchanger. The controller is designed by incorporating a selected macro variable with a time-varying sliding surface. The primary objective is to maintain precise control over the outlet temperature of the cold water. To assess the convergence characteristics of the newly proposed TSC approach, the simulation results achieved using TSC featuring a time-varying macro variable are compared to those obtained from the conventional synergetic control (SC) method. With an appropriate macro variable, the simulation results indicate a notable improvement in the convergence rate provided by our designed TSC method, compared to the conventional one. The desirable property of control input, the chattering-free condition, achieved by both TSC and SC approaches emphasizes the advantage of the synergetic control-based techniques over the conventional sliding mode controller. In conclusion, synergetic control-based techniques offer superior potential solutions for nonlinear feedback control problems.

Investigation of the Effect of Heat Transfer during Friction Stir Welding (FSW) of AZ80A Mg Alloy Plates using a Pin Tool by Conducting Finite Elements Analysis
Authors: Imad O. Bachi Al-Fahad  , Hussein Kadhim Sharaf
Published: May 2024

Friction stir welding (FSW) is an innovative solid-state welding process that has attracted substantial attention due to its potential for combining problematic materials such magnesium alloys, such as AZ80A. In order to better understand the impact of heat transport during FSW of AZ80A magnesium alloy plates using a pin tool, this study used finite element analysis (FEA). The welding process's thermal features, such as temperature distribution, thermal stresses, and material flow patterns, are the major focus of this analysis. The first step of the study is to conduct a comprehensive literature evaluation to lay a firm groundwork and pinpoint knowledge gaps. The thermal conductivity, specific heat, density, and mechanical characteristics of AZ80A magnesium alloy are measured and recorded as part of the material characterisation process. To ensure an exact simulation of real-world welding circumstances, a comprehensive 3D model of the welding setup is built, including the AZ80A magnesium alloy plates and the pin tool. In order to accurately record temperature variations, a tiny mesh is used, particularly in the welding zone. By include boundary conditions that mimic the real-world welding characteristics, such as the rotation of the pin tool and the clamping or fixturing of the plates, finite element analysis is used to model the FSW procedure. To simulate the heat input produced by FSW, a heat source or heat production model is used.

Published: May 2024

Nanoparticles are structures that are applicable to a wide range of fields. The most significant characteristic of these structures is their structural and dimensional diversity, which varies the synthesis process based on the area that will be incorporated into several sections. Although there are other synthetic techniques, the green synthetic technique is the most often used. By employing only natural processes instead of chemicals, this method synthesizes products leaving no by-products. The technique is also highly preferred as it is affordable. In this respect, the green synthesis approach was utilized in this study to investigate the synthesis characteristics, phytochemical content, and evaluate the antibacterial activity of silver nanoparticles from black pepper (Lavandula stoechas), which is commonly used as a sweetener in food and beverages. Furthermore, theoretical investigation was conducted into the glucosamine-6-phosphate synthase inhibitory characteristics of the resveratrol molecule, which was identified as the main constituent based on the HPLC outcome. Characterization tools like FT-IR, UV-Vis, and fluorescence spectroscopy were employed. The phytochemical content was examined by HPLC.

Amaç: İleri evre over malignitelerinde cerrahi sonrası morbidite nedenlerini, hastanede yatışla ilişkili risk faktörlerini değerlendirmek.
Gereçler ve Yöntem: Eylül 2018–Aralık 2023 tarihleri arasında Mersin Üniversitesi Jinekolojik Onkoloji Bilim Dalı’na başvuran evre III over malignitesi tanısı olan 88 hasta çalışmaya dahil edildi. Hastaların demografik bilgileri, kanserin histolojik tipleri, tedavinin yönetimi ve sitoredüktif cerrahinin kapsamı, komplikasyonlar ve yönetimi, yoğun bakım ihtiyacı, morbidite ve erken dönem yatış süreleri, hastaneye yeniden kabuller ve müdahaleler değerlendirilmiştir.
Bulgular: Primer sitoredüktif cerrahi (PSC) sonrası hastaların %70.6’sında, nüks sonrası cerrahilerin %74.1’inde, neoadjuvan kemoterapi sonrası interval sitoredüksiyon (NAKS-IS) yapılan hastaların %70.4’ünde komplet sitoredüksiyon sağlandı. Postoperatif erken dönemde morbiditenin en sık nedenleri sırası ile %17 yara yeri enfeksiyonu, %10.2 atelektazi, bulantı-ileus %9.1 idi. Yara yeri enfeksiyonu, atelektazi, ileus, tromboemboli görülme sıklığı açısından istatistiki olarak guruplar arası fark yoktu(p=0.537). Postoperatif dönemde yatış süresi ve 2. basamak yoğun bakım ihtiyacı açısından yönetimler arası fark yoktu(p>0.05). Postoperatif hospitalizasyonun en sık nedeni yara yeri enfeksiyonudur.
Sonuç: Tedavi yönetimlerimiz arasında ve sitoredüksiyon başarıları açısından fark yoktu(p>0.05). NAKS-IS’in PSC’ye göre cerrahi süresi, yoğun bakım ihtiyacı, hastanede kalış süresi bakımından avantajlı bulunmuştur. Sitoredüksiyon oranları ve postoperatif komplikasyonlar açısından fark bulunmamıştır(p>0.05). Yara yeri enfeksiyonunun NAKS-IS te PSC’ye oranla fazla olma nedenini NAK bağlı sitopeni ile ilişkilendirebiliriz. PSC’de NAKS-IS’e kıyasla hızlı patoloji kullanımı, ameliyat süresi, postoperatif atelektazi ve ileus oranları artmıştır. Sitoredüktif cerrahi sonrası yara yeri enfeksiyonu, atelektazi, ileus ve tromboemboli açısından hastaların yakın takibi önemlidir.
BITCOIN PRICE AND CHINESE GREEN BONDS: EVIDENCE FROM THE QARDL METHOD

This article primally explores the short-term fluctuation and long-term implications of the international Bitcoin price (BP) on the Chinese green bond (GB) market, within the sample period of 2014:M10–2023:M07. Bitcoin is the most important cryptocurrency and has a carbon-intensive feature, and its price suffers from great volatility and is closely related to the green finance market. Meanwhile, although China is the largest bitcoin mining state, it is pursuing a dual carbon target, which promotes its green bond market’s development. Thus, it is valuable to investigate the influence of BP on GBs in China. Based on the quantile autoregressive distributed lag approach, this paper indicates that the positive and negative impacts of BP on the GB market are significant in the long-term but not apparent in the short-term. These results emphasize the importance for market participants to obtain a better understanding of how BP affects GB under various market circumstances. Implementing specific policies, such as regulatory mechanisms for Bitcoin trade, market-oriented reform for the bond market, and information disclosure, can alleviate shocks from BP and accelerate the development of the GB market.

Herein, we present the statistical properties of active galactic nuclei (AGNs) for approximately 1 million member galaxies of galaxy groups and clusters with 0.1 < cluster redshift (z
cl) < 1.4 selected using the Subaru Hyper Suprime-Cam, the so-called CAMIRA clusters. In this research, we focused on the AGN power fraction (f
AGN), which is defined as the proportion of the contribution of AGNs to the total infrared (IR) luminosity, L
IR (AGN)/L
IR, and examined how f
AGN depends on (i) z
cl and (ii) the distance from the cluster center. We compiled multiwavelength data using the ultraviolet–mid-IR range. Moreover, we performed spectral energy distribution fits to determine f
AGN using the CIGALE code with the SKIRTOR AGN model. We found that (i) the value of f
AGN in the CAMIRA clusters is positively correlated with z
cl, with the correlation slope being steeper than that for field galaxies, and (ii) f
AGN exhibits a high value at the cluster outskirts. These results indicate that the emergence of the AGN population depends on the redshift and environment and that galaxy groups and clusters at high redshifts are important in AGN evolution. Additionally, we demonstrated that cluster–cluster mergers may enhance AGN activity at the outskirts of particularly massive galaxy clusters. Our findings are consistent with a related study on the CAMIRA clusters that was based on the AGN number fraction.

We analyze rest-frame ultraviolet to optical spectra of three z ≃ 7.47–7.75 galaxies whose Lyα emission lines were previously detected with Keck/MOSFIRE observations, using the JWST/NIRSpec observations from the Cosmic Evolution Early Release Science survey. From NIRSpec data, we confirm the systemic redshifts of these Lyα emitters, and emission-line ratio diagnostics indicate these galaxies were highly ionized and metal-poor. We investigate Lyα line properties, including the line flux, velocity offset, and spatial extent. For the one galaxy where we have both NIRSpec and MOSFIRE measurements, we find a significant offset in their flux measurements (∼1.3–5× greater in MOSFIRE) and a marginal difference in the velocity shifts. The simplest interpretation is that the Lyα emission is extended and not entirely encompassed by the NIRSpec slit. The cross-dispersion profiles in NIRSpec reveal that Lyα in one galaxy is significantly more extended than the nonresonant emission lines. We also compute the expected sizes of ionized bubbles that can be generated by the Lyα sources and discuss viable scenarios for the creation of sizable ionized bubbles (>1 physical Mpc). The source with the highest-ionization condition is possibly capable of ionizing its own bubble, while the other two do not appear to be capable of ionizing such a large region, but require additional sources of ionizing photons. Therefore, the fact that we detect Lyα from these galaxies suggests diverse scenarios for the escape of Lyα during the epoch of reionization. High-spectral-resolution spectra with JWST/NIRSpec will be extremely useful for constraining the physics of patchy reionization.
Modeling the Saturation of the Bell Instability Using Hybrid Simulations

Published: May 2024

The nonresonant streaming instability (Bell instability) plays a pivotal role in the acceleration and confinement of cosmic rays (CRs), yet the exact mechanism responsible for its saturation and the magnitude of the final amplified magnetic field have not been assessed from first principles. Using a survey of hybrid simulations (with kinetic ions and fluid electrons), we study the evolution of the Bell instability as a function of the parameters of the CR population. We find that at saturation, the magnetic pressure in the amplified field is comparable with the initial CR anisotropic pressure, rather than with the CR energy flux, as previously argued. These results provide a predictive prescription for the total magnetic field amplification expected in the many astrophysical environments where the Bell instability is important.
