Religious Marriage in Indonesia in the Perspective of Islamic Law and Positive Law in Indonesia : Legal Comlexities and the Issuance of Supreme Court Circular Letter No. 2 of 2023
Authors: Rusman Rusman , Hidayat Yusuf , Rifai Anis
Published: November 2023

This normative legal research aims to clarify the regulation of interfaith marriages in Indonesia, considering both positive law and Islamic law perspectives, and assess the impact of Circular Letter No. 2 of 2023 on legal certainty in this matter. The study found that the 1974 Marriage Law lacks comprehensive protection for interfaith marriages. Islamic law, particularly according to the Indonesian Ulema Council (Mui), tends to prohibit such marriages due to perceived violations of fiqh principles, such as preventing harm (sadd al-zarî’ah). Despite these differing opinions, Circular Letter No. 2 of 2023 is expected to provide legal clarity and potentially resolve the controversy surrounding interfaith marriages in Indonesia. The Supreme Court's prohibition on interfaith marriages has sparked debates and protests in society, with some activists arguing that the court's order is a clear violation of people's constitutional rights, such as freedom of religion. Highlights: The study aims to clarify the regulation of interfaith marriages in Indonesia, considering both positive law and Islamic law perspectives, and assess the impact of Circular Letter No. 2 of 2023 on legal certainty in this matter.

K-means and RS based DEA model and its application in Chinese low-carbon efficiency
Authors: Shen Chaofeng , Zhang Jun
Published: November 2023

Since the evaluation results of DEA method are difficult to reflect the differences among many samples, the rough set idea is introduced, the comprehensive efficiency value solved by DEA is taken as the decision attribute, and other indicators are taken as the conditional attribute, and the index is relatively reduced. On the one hand, the kernel attribute is extracted to reduce the redundancy among indicators and maintain the unity of the index system. On the other hand, the provinces with effective and invalid DEA results are segmented into low input and high output, high input and high output, low input and low output, and then the low carbon efficiency of different provinces can be analyzed and the solution direction can be proposed. However, the data used in rough sets must be discretized data. In this paper, the contour coefficient method is used to optimize the K-means algorithm to obtain the optimal cluster number and classification results, so that the discretized data obtained can be used for the relative reduction of rough sets. The results show that Anhui, Hunan, Jiangxi, Chongqing, Guizhou, Shaanxi and Heilongjiang with invalid DEA show low input and low output and high input and low output. The provinces with effective DEA and high output and low input and high output are Shanghai, Gansu, Qinghai, Yunnan, Xinjiang, Henan and Zhejiang with the best low carbon efficiency. The provinces with high input and low output of DEA are Beijing, Hubei and Sichuan, which do not allocate resources well and have the worst low-carbon efficiency. On the whole, the distribution of low carbon efficiency has spatial autocorrelation, and there are high-high aggregation, high-low aggregation and low-low aggregation.
Eastern Redcedar: A United States Native Tree That Ranges from Useful, to a Nuisance, and Even Invasive in Certain Environments
Authors: Schnelle Michael A.
Published: November 2023

Invasive and nuisance plants, both introduced as well as native, have negatively impacted native flora and fauna and altered hydrological processes. Economic damage estimates range from $1.4 trillion globally to as high as $120 billion in the United States. Eastern redcedar (Juniperus virginiana) is native to at least 37 states in the United States. A medium-sized tree, eastern redcedar is commonly used as a landscape ornamental given its ability to grow in a wide range of conditions and its tolerance to many environmental pollutants. A tenacious conifer, eastern redcedar is valued for its landscape value and other uses, including wildlife habitat, lumber, medicines, and more. However, with wildfires suppressed and prescribed fires often discouraged, eastern redcedar has grown outside its original habitat and is an example of the term “range change.” This species’ predisposition to be opportunistic has allowed it to encroach on both abandoned and cultivated fields as well as grasslands. When the tree exhibits nuisance tendencies, control measures are warranted including prescribed fire, mechanical control, and herbicides. Ultimately, integrated control measures culminate in the best long-term results. The objective of this article was to describe eastern redcedar’s desirable ornamental features as well as landscape and utilitarian uses for humans and animals but also outline that it can be weedy to invasive depending on several factors discussed herein.
Site Factors Related to Dry Farm Vegetable Productivity and Quality in the Willamette Valley of Oregon
Authors: Davis Matthew , Stone Alexandra , Gallagher Andy , Garrett Amy
Published: November 2023

Dry farming has been defined as rainfed crop production in a climate with more than 20 inches of annual precipitation, but where most precipitation falls outside the growing season. Dry farming is garnering interest in the western United States because it allows farmers to produce crops despite a lack of access to irrigation or water rights or to eliminate the infrastructure, labor, and energy costs of irrigation systems. Sites have differing suitability for dry farming, and some sites that can be farmed with irrigation will perform poorly when dry-farmed. To determine site factors associated with dry farm yield and fruit quality, trials of ‘Early Girl’ tomato (Solanum lycopersicum) and ‘North Georgia Candy Roaster’ winter squash (Cucurbita maxima) were conducted at 17 participant farms in the Willamette Valley in Oregon, USA, in 2018 and 2019. The mean blossom-end rot (BER) incidence was higher in the Willamette Valley than in coastal California; this was probably because of the Willamette Valley’s hotter and drier climate. Increasing the available water-holding capacity of soil, total available water (available water-holding capacity of the soil plus in-season rainfall), native productivity rating, soil pH (0–6 inches and 24–36 inches), soil nutrient concentrations (0–6 inches and 24–36 inches), and in-season rainfall were positively associated with at least one measure of tomato or winter squash yield, fruit number, or average fruit weight. An earlier planting date was positively associated with winter squash total yield and total fruit number in 2019. The water-limited yield potential (the total yield potential if water was the only limiting factor) for 20-ft2/plant plots was estimated to be 2.2 tons/acre per inch for tomato and 2.8 tons/acre per inch for winter squash. In 2019, high-density plantings (20 ft2/plant) had higher tomato and winter squash mean total yields, mean total fruit numbers, and mean tomato unblemished yield than low-density plantings (40 ft2/plant). In 2019, planting tomato at 20 ft2/plant decreased the mean BER incidence by 15.6% when compared with planting tomato at 40 ft2/plant.

Authors: Wuisan Dewi , Hermawan Asep , Antonio Ferdi , Pramono Rudy
Published: November 2023

This study aims to determine the effect of peer-to-peer lending (P2PL) on small and medium enterprises (SMEs) underpinned by the theory of planned behavior and asses its impact on the borrower’s intention to recommend such a platform. This paper used a quantitative survey method with partial least squares structural equation modeling to analyze the data collected through a questionnaire. The data were obtained from 395 respondents who are entrepreneurs or business leaders in SMEs in Indonesia and had experience in borrowing business loan funds from the P2PL apps. The structural questionnaire was distributed from January to May 2022. The results of this study indicate that the three core components of the theory of planned behavior (attitudes, subjective norms, and perceived behavioral control) can significantly influence the intention to continue usage and the intention to recommend with an R-squared value of 0.626, which indicates a meaningful explanatory power. The results proved that perceived benefits and risk and electronic word-of-mouth are the antecedents with significant influence. Moreover, this study provides new insights into how self-efficacy and mental accounting can influence perceived behavioral control. These findings could suggest that P2PL management should be more innovative in developing effective marketing strategies based on the traits and borrower’s points of view. Particularly, they could emphasize customer segmentation based on mental accounting.

ZEIN/PVA NANOPARTICLES LOADED WITH EUGENOL AND CLOVE ESSENTIAL OIL: OPTIMIZATION OF SYNTHESIS AND ANALYTICAL VALIDATION FOR EUGENOL QUANTIFICATION. Nanoparticles of zein (NPZ) stabilized with surfactant polyvinyl alcohol (PVA), and nanoparticles of zein/PVA loaded with eugenol (NPZ-Eug) and the essential oil extracted from the clove (Syzygium aromaticum) (NPZ-OC) were produced by nanoprecipitation method. The extraction method of essential oil of the clove was carried out by the hydrodistillation technique, obtaining a content of 81.5% (m/m) of eugenol. The nanoparticle preparation method was optimized using a one-factor-at-a-time design of experiments, where different levels of variables (zein concentration, PVA concentration, and eugenol concentration) were explored. The best condition of synthesis was obtained with 0.3% (m/v) zein, 0.6% (m/v) PVA and 1.5 mg L-1 eugenol or essential oil of the clove, reaching NPs with acceptable propriety for stable nanoparticulate systems: size particles (NPZ = 113, NPZ-Eug = 229 and NPZ-OC = 279 nm), polydispersity index (PDI < 0.26), and zeta potential (≈ −30 mV). Loaded NPs showed encapsulation efficiency and drug-loading of 52 and 20% (NPZ-Eug), and 62, 27% (NPZ-OC), respectively. The quantification method of eugenol was validated by analytical parameters. Finally, all NPs produced exhibited good colloidal stability, confirming the effectiveness of PVA as a stabilizing agent, which had not been previously reported for these systems. The results obtained provide promising prospects for further investigations into its potential application as a bioinsecticide agent.

Published: November 2023

Wastewater is considered a source of water, power, and enriching nutrient for plants. Wastewater treatment is among the most significant biotechnological procedures for treating municipal and industrial sewage across the world. Conventional wastewater treatment methods, however, have constraints, primarily because they are cost-intensive to achieve the aim of wastewater remediation. Microorganisms, on the contrary, outperform humans when it comes to sewage water purification. Their ability to decompose a wide range of organic chemicals and cycle components such as nitrogen, phosphorus, and carbon is unparalleled in ecology. These characteristics have been successfully used in microbial wastewater treatment plants. This chapter discusses the necessity for wastewater treatment, and the function of diverse microbes in wastewater treatment, including new and developing technologies that use microbes for wastewater treatment and purification, such as microbial fuel cells, bioremediation, and activated sludge processes along with the challenges and prospects of using microorganisms in wastewater treatment.

Authors: Sengupta Tanusree , Mitra Arup Kumar
Published: November 2023

The various everyday developments of our urban society have led to the improvement of industries and agricultural growth causing the mismanagement of wastewaters coming out from these industries. This wastewater exerts many faceted pollution issues leading to the biomagnification and thus affecting human population. Bioremediation is one of the most effective methods of removing hazardous impurities from wastewater. Due to their role as bio indicators in showing the status of any environment, zooplankton have been used to remove the effects of hazardous pollutants from wastewater and thus aid in bioremediation for a while. Zooplankton and other microbes act to remove or reduce pollutants through biological degradation of pollutants into nontoxic substances. Several parameters decide the correct method of bioremediation among in situ or ex situ methods. Processes like bio stimulation, bioaugmentation, bioventing, bio piles and bio attenuation are required to develop a complete bioremediation process.

Published: November 2023

The application of nanotechnology in the area of environment has been studied extensively. With the rise in environmental challenges, one of biotechnology's primary concerns is the remediation of the environment. This technique can be called bioremediation and it works to decontaminate the environment by using microorganisms like fungi or their enzymes to break down hazardous compounds into non-hazardous ones. The combination of various particle and organism types, including fungi along with nanotechnology, can offer ecologically responsible alternatives for bioremediation. Nanoparticles are one of the varieties of nanomaterials and have found extensive use in a wide range of applications. Iron oxide nanoparticles were considered a good candidate for nanoparticles that is appropriate for usage in biosystems because of their chemical stability and low toxicity. As a result, components like bioactive nanoparticles, nanocomposites, and nanocatalysts have been used more in the creation of procedures and techniques for cleaning up an environment contaminated with chemical waste.

Authors: Garkoti Pankaj , Tiwari Harshit , Sarkar Priyanka , Bhunia Biswanath
Published: November 2023

About 400 trillion liters of wastewater is generated yearly due to widespread and inefficient water use. The wastewater from different sources contains many nutrients, including nitrogen, phosphorous, and carbon. Therefore, these nutrients must be recovered using appropriate sustainable processes. The selection of the proper process depends upon the type of waste and its generation. Hence, there is a need to implement a biorefinery approach to utilize organic and biological pollutants to recover energy and bioproducts. For sustainable and inexpensive wastewater treatment, microalgae-based processes have garnered considerable interest. The biomass produced by microalgae can be used in bioenergy production and other value-added products. Thus, this chapter provides state-of-the art information regarding the potential of biomass-based integrated biorefineries for effluent treatment.
Analysis of extreme annual rainfall in North-Eastern India using machine learning techniques
Authors: Agarwal Shivam , Mukherjee Disha , Debbarma Nilotpal
Published: November 2023

The machine learning techniques of Multiple Linear Regression (MLR), Generalized Additive Models (GAMs), and the Random Forest (RF) Method have been used to analyze the extreme annual rainfall in the six states of Assam, Meghalaya, Tripura, Mizoram, Manipur, and Nagaland in North-Eastern (NE) India. Latitude, longitude, altitude, and temperature were the covariates that were used in this study. Ordinary Kriging was used to interpolate the predicted outcomes of each dataset. Statistical metrics like Mean Absolute Errors (MAE), Root Mean Square Error (RMSE), Coefficients of Determination (COD-R2), and Nash–Sutcliffe Efficiency (NSE) were also assessed. When compared to satellite rainfall data, all techniques performed significantly better for ground rainfall data. For prediction, GAM's predicted rainfall values triumph over MLR or RF. RF ranks a close second, while the linearity of MLR prohibits it from making precise predictions for a physical phenomenon like rainfall. The MAE and RMSE of GAM forecasts are significantly lower than those of MLR and RF in most circumstances. Additionally, the COD and NSE of GAM predictions are significantly better than both MLR and RF in most cases, showing that GAM, out of MLR, GAM, and RF, is the best model for predicting rain in our research area.

The value of the posterior ligamentous complex in traumatic injury of thoracolumbar junction. Part 1. Morphology and biomechanics
Authors: Nekhlopochyn O.S. , Verbov V.V. , Cheshuk I.V. , Vorodi M.V.
Published: November 2023

According to modern concepts, one of the basic criteria for the stability of the spinal motion segment in case of its traumatic damage is the integrity of the posterior ligamentous complex (PLC). Regarding the thoracolumbar junction (TLJ) as a zone that is most vulnerable to traumatic injuries, the Thoracolumbar Injury Classification and Severity Score and the clinically oriented AO Spine Thoracolumbar Spine Injury Classification System are used in determining therapeutic approaches in which the state of the thoracic spine is one of three key parameters. The term PLC was first proposed in 1963 by F.W. Holdsworth. However, only the widespread introduction of magnetic resonance imaging into clinical practice made it possible to fully reveal the informativeness of the specified parameter. The complex includes the interspinous, supraspinous ligaments, ligamentum flavum and facet joint capsule. The purpose of the review is to organize modern ideas about the morphology, biomechanical features, clinical significance, and diagnostic possibilities of detecting damage to the PLC in traumatic injuries of the TLJ area. In the first part, the morphological and biomechanical features of the PLC of the TLJ zone are considered in detail. When describing the morphology of some ligaments, the main attention is paid to their length, fixation zones, and certain layers, if such are distinguished. In addition, the relative anatomical location of the considered structures was taken into account. Histological features are indicated only in terms of their biomechanical significance. The analysis of literature data made it possible to organize the data characterizing the biomechanical parameters of each ligament of the PLC for each spinal motion segment of the area under consideration. Stiffness indicators, breaking force, fracture energy, strength and deformation limits, maximum deformation and elastic modulus were taken into account. The features of the load-deformation curve of the TLJ ligaments and methods of calculating the nonlinear change in the stiffness of each ligament of the PLC within the limits of physiological loads are considered. The phenomenon of preload and its clinical significance are described. Some aspects of the interaction between the elements of the passive stabilization system under different load patterns are considered. The data presented in the first part of the review can be useful for a general understanding of the principles of biomechanics of the spinal motion segment and may be used in the construction of highly detailed computer models.

Published: November 2023

Background. Currently, there is an increase in the lower limb fractures (47.3 %). More than 50 % of complications are related to the treatment of tibial fractures, which caused 27.9 % of disability. Goal: to conduct a comparative analysis of the stress-strain state of the tibial models with a fracture in the upper third with different options of osteosynthesis under bending load depending on the patient’s weight. Materials and methods. The model simulated a tibial fracture in the upper third and three types of osteosynthesis using an external fixation device (EFD), a bone plate and an intramedullary rod. The models were tested under the influence of a bending load of 700 and 1200 N. Results. Normally, the stress under bending load is maximal in the distal tibia. When using EFD, the maximum stress level is observed in the distal fragment of the tibia. During osteosynthesis with a bone plate, the stresses are maximal in the fracture zone. Osteosynthesis with an intramedullary rod provides the lowest stress level in the fracture zone. An increase in the load up to 1200 N leads to an elevation in the stress values in all elements of the model. Conclusions. Under bending loads, indicators of the stress level in the fracture zone and the metal structure were the worst when using a bone plate. Osteosynthesis with the help of EFD ensures the lowest level of stress in the fracture zone, it is also worth noting the lowest level of stress on the device itself. Quite low stress indicators in the fracture zone and in the proximal fragment of the tibia occur when using osteosynthesis with an intramedullary rod.

In the context of radio, the gist of development communication is how the radio is used to aid social development. Although there are studies on radio listenership, research on women's listening habits in Malaysia is inadequate, although women are dominant radio listeners globally. This study examines factors that motivate women's listening to the radio, mainly in Semporna, Sabah. The central question is how radio has become significant among women in Semporna? This research employs a quantitative research approach. A structured questionnaire was used to obtain information from 294 female respondents. A chi-square test, factor analysis, and Kruskal-Wallis test with Bonferroni correction were used to analyse the data. The findings of the chi-square test analysis revealed a significant link between radio listening and possessing a radio set at home (X2 = 33.871, df = 1, p 0.05). The Kruskal-Wallis test with Bonferroni correction was conducted to see whether the agreement score in listening to the radio for entertainment and peace of mind is different according to four factors: age, marital status, level of education and occupation. Thus, radio is no longer the primary medium to get information, except for undocumented people.
Challenges in conserving Intangible Cultural Heritage in Vietnam as seen from the Van Phuc Silk Village
Authors: Son Nguyen Huu
Published: November 2023

Traditional handicrafts in Ha Dong, Van Phuc, Vietnam, are the subject of this study. Crafts are portable and manufactured by craftsmen with artistic and manual talents, serving immediate demands and are traded and exchanged. They may exhibit cultural significance and symbolic values of gender, age, ethnicity, and nationalism, forming part of social and religious beliefs. Unfortunately, growing industrialization, globalisation, and commodification have limited them. The Van Phuc village is a great case study for how it survived and developed during urbanisation and industrialization. Applying qualitative research, data was collected through offline observations, interviews, and document analysis from 2017-2021. This study found that lack of basic infrastructure, less competitive products, traditional crafts style, and anxiety for future succession have inhibited the village's promotion of its values. To help stakeholders understand and safeguard the village, some implications are proposed.

Harmonizing Emotions: A Musical Journey through Innovative Extrapolation
Authors: Kumar Rahul
Published: November 2023

Abstract: In the symphony of life, music serves as a powerful conductor of emotions, weaving intricate patterns that resonate within the depths of our souls. The quest for joy and the alleviation of melancholy often find solace in the artistry of musicians and composers. Yet, in our digital age, where music is fragmented into bite-sized pieces, the challenge emerges: how can we transform fleeting moments of musical bliss into a sustained, transformative experience? This research endeavors to explore a novel solution to this conundrum, proposing an innovative idea that involves generating sequential 10-second music chunks. These musical fragments, when skillfully combined, have the potential to orchestrate a seamless composition of desired duration, thus unlocking a symphony of emotions. Delving into the intricacies of human psychology, the study challenges the conventional belief that repetitive exposure to a short musical piece can adequately replace the profound impact of a longer composition. By extrapolating the musical experience, we aim to bridge the gap between the ephemeral and the enduring, offering a unique pathway to emotional resonance. Join us on this melodic journey through the nitty-gritty details of our solution, where each note becomes a stepping stone towards a richer, more immersive musical experience. As we navigate the intersection of innovation and emotion, the allure of extended musical euphoria awaits discovery, promising to revolutionize the way we perceive and experience the transformative power of music.
