Published: January 2024

This article focuses on the evolution and development of liberalism especially in Malaysia since being brought by western colonizers till form social movements in Malaysia preliminary. The philosophy of liberalism in Malaysia is not a newly thought issue, but one that has existed among Malaysian Muslim community for a long time. Throughout the history, the liberalism ideology has evolved among the people of Malaysia since it was first brought in, it is known as liberal Islamic movements. In the modern times, Liberalism's advocates have increasingly and rapidly embraced the ideology of liberalism, especially through the liberal Islamic movement and in the name of human rights. Although liberalism has been part of the society in the areas of life such as economy, politics, culture, law and administration in Malaysia, the development and dissemination of the liberalism ideology can lead to a threat in ‘aqidah (faith) especially among Muslims today in Malaysia.
المرابحة المصرفية و تطبيقاتها المعاصرة: دراسة تحليلية نقدية Banking Murābaḥah and its Contemporary Applications: An Analytical Critical Study
Authors: Benaouali Mohamaed Cherif
Published: January 2024

Banking murābaḥah is one of the most popular and commonly offered financing product in Islamic banks and windows. It was introduced as a legitimate alternative for customers who wish to enter into Sharīʻah-compliant transactions that are interest-free. Despite its wide use, several contentious issues were observed in relation to its application. Therefore, this study attempts to present the Sharīʻah viewpoint of the banking murābaḥah product in terms of its concept and conditions, followed by highlighting the opinions and evidence of contemporary jurists. The study will also discuss and critically analyze the most contentious Sharīʻah issues related to the application of banking murābaḥah, such as the use of binding promise, delay penalties, and interest-based benchmark for determining the profit. This will be followed by focusing on the practical aspects of the banking murābaḥah product applied in Al-Salam Bank in Algeria. The study concludes by suggesting several Sharīʻah solutions and alternatives to ensure the sound application of the product. The study reaches the conclusion that banking murābaḥah is an innovative and contemporary product that is permissible subject to certain conditions, among which is the avoidance of relying on a binding promise, whether unilateral or bilateral, rather it should be executed on the basis of conditional option between the bank and the customer to complete the transaction or cancel it. The non-binding nature of the transaction makes it free from the suspicion of usury, and in compliance with the requirement of consent, which is a condition for the validity of the sale.

Authors: Darusman Darusman
Published: January 2024

Organic waste is a serious problem in big cities. Eco Enzyme and Green Tonic fertilizer are used to solve the problem and increase the growth of chili plants. Research comparing the macro content of both is needed. Eco Enzyme analysis activities were carried out at the Soil Laboratory, Faculty of Agriculture, Mulawarman University. The activity of planting chili plants was carried out in one of the researcher's houses. The activities carried out in this study were carried out in two stages, namely the first stage of analysing the content of Eco Enzyme and Green Tonic Fertilizer and the second stage of planting chili plants. Green Tonic Fertilizer has a higher Nitrogen content than Eco Enzyme. However, Eco Enzyme has a higher Potassium content than Green Tonic Fertilizer. Based on the results of the research activities that have been carried out, it can be concluded that; observation of the height of chili plants after the experiment shows that the interaction effect and the main effect of applying eco enzyme has a significant effect on the height of chili plants compared to applying Green Tonic fertilizer and the results also show that many leaves using eco enzyme are better than Green Tonic fertilizer.

Published: January 2024

In this study, the method of analysis of iodine by UV-Vis spectrophotometry was validated. Two other solvents, ethanol, and cyclohexane were used to validate this approach. The UV-Vis Spectrophotometer method's linearity, detection, and quantization limitations, precision, and accuracy were investigated as variables. The results of the linearity tests indicated that the method was proportionally verified because the r values for the two iodine solutions in ethanol and cyclohexane varied between 0.990 and 0.999, respectively. This suggests that the values were higher than 0.99. The LOD values for the ethanol solvent were 4.441 mg/kg and the LOQ was 14.802 mg/kg, whereas the cyclohexane solvent had an LOD value of 2.660 mg/kg and the LOQ was 8.866 mg/kg. According to the required precision acceptance, the %RSD value of 2%, precision values for both standard iodine solutions with two modifications of solvents demonstrated good results. Recovery percentages of ethanol solvents are 96% and cyclohexane solvents are 86%, respectively, according to accuracy measurements. The combined uncertainty value for this test is 0.109 for the ethanol solvent and 0.019 for the cyclohexane solvent, respectively. This research provides a comprehensive understanding of the validity of the iodine analysis method, establishing a robust foundation for the sustainability and reliability of using UV-Vis spectrophotometer in the analysis

The production of herbal beverages such as ginger, turmeric, and other spices generates waste that is commonly discarded. The cellulose content in red ginger is about 60-80%, and in turmeric, it is 50%. The high cellulose content makes red ginger and turmeric waste suitable for use as raw materials for paper production. The objective of this research is to determine the optimum conditions for making paper based on red ginger and turmeric waste. The pulp formation process was carried out using the Semi-Mechanical Method, which involves the addition of chemical solutions and grinding, on a mixture of turmeric and red ginger waste (60:40) with variations of NaOH concentration at 8%, 10%, and 13% (w/v). The papermaking process began with refining and drying the waste, cooking the pulp, adding water and kaolin filler, and then printing. Characterization included antibacterial testing, tensile strength, and grammage. Based on the pulp characterization results at the optimum NaOH concentration of 8%, the moisture content was 8.89%, cellulose content was 49.28%, and lignin content was 9.28%. These parameters comply with the national standard (SNI) for packaging paper. The paper characterization results showed a tensile index of 2.12 Nm/gram, an antibacterial inhibition zone of 5 mm, and a grammage of 13 g/m2. This research indicates that the NaOH concentration influences the moisture, cellulose, and lignin content. Furthermore, based on the characterization results, paper made from turmeric and ginger waste has the potential to be used as antimicrobial packaging paper.

Industrial development impacts environmental problems, such as the emergence of wastewater containing methylene blue. In this research, SiO2 was composited with ZnO to remove methylene blue. The steps of this study include SiO2 extraction from geothermal solid waste, ZnO/SiO2 synthesis, and methylene blue removal test. The process of extracting SiO2 from geothermal solid waste used the sol-gel method. The FTIR analysis showed that SiO2 contains siloxane group (Si-OH) and silanol group (Si-O-Si). ZnO/SiO2 synthesis was done by making SiO2 suspension and continued with adding the addition of several Zn(NO3)2.6H2O. The FTIR analysis of ZnO/SiO2 showed no absorption at the wavenumber 960 cm-1 and there is a shoulder around the number 950 cm-1 which indicates the vibration of Si-O-Zn. Meanwhile, methylene blue removal tests were carried out on artificial wastewater. Based on the research results, the highest percent removal (99%) was obtained under operating conditions, including a dose of 500 mg/L, pH 10, and contact time of 30 minutes. Based on box-benkhen analysis, it is known that dose and pH singularly affect the percent removal, while contact time does not affect the percent removal. The optimization results obtained optimum conditions for methylene blue removal at a dose of 581.952 mg/L, pH of 10, and contact time of 30 minutes. Percent removal in conditions without irradiation and with irradiation of UV light were 98.758% and 99.178%. It shows that the adsorption process is the main process in removing methylene blue, while the photocatalytic process has little effect because it is possible that only a small amount of ZnO can attach to the surface of SiO2.
Arctic Amplification during the Last Glacial Inception due to a delayed response in sea ice and surface temperature
Authors: Xu Shan , Krebs-Kanzow Uta , Lohmann Gerrit
Published: January 2024

The last glacial inception (LGI) marks the transition from the
interglacial warm climate to the glacial period with extensive Northern
Hemisphere ice sheets and colder climate. This transition is initiated
by decreasing summer insolation but requires positive feedbacks to
stimulate the appearance of perennial snow. We perform simulations of
LGI with climate model AWI-ESM-2.1, forced by the radiative and
greenhouse gas forcing of 115,000 years before present. To compare with
the preindustrial (PI) simulation, we use a consistent definition of the
seasons during the LGI and the PI and evaluating model output on an
angular astronomical calendar. Our study reveals a prominent role of sea
ice in the albedo feedback to amplify the delayed climate siregnal at
polar latitudes. Through a radiative budget analysis, we examine that
the ice-albedo feedback exceeds the shortwave radiative forcing,
contributing to the cooling and high latitude snow built-up during LGI.

Authors: Nicita Fabiana , Calapaj Massimo , Alibrandi Simona , Donato Luigi , Aquilio Emidio , D’Angelo Rosalia , Sidoti Antonina
Published: January 2024

Objectives

To assess effectiveness of an experimental sterilization method based on the exposure of an O3/O2 gas mixture directly inside the packaging for clear aligners.

Materials and Methods

Fifty samples consisting of pieces of polyethylene terephthalate glycol (PET-G) aligners were contaminated by manual handling and subsequently divided into different groups (n = 30 for exposure to O3/O2 gas at different times, n = 10 for positive control with 2% chlorhexidine digluconate, n = 10 for negative control). The measurement of optical densities (OD) of the initial and final microbial cultures was recorded for all groups. Kruskal-Wallis test was used for differences between groups while Wilcoxon test was used to compare initial and final OD values within groups. Statistical significance was set at P < .05.

Results

Comparison within the groups showed statistically significant differences for exposure to the gaseous mixture (72 hours), for positive and negative controls. Other significant differences were found in the multiple comparisons between the application of gaseous ozone (48 hours and 72 hours) and the negative control.

Conclusions

The direct exposure of gaseous ozone on the aligners inside their packaging showed microbicidal capacity at 72 hours, which was equivalent to the positive control with immersion in chlorhexidine digluconate. This innovative sterilization procedure could be considered in the final manufacturing processes of clear aligners to eliminate the potentially pathogenic microorganisms that are deposited on surfaces of these orthodontic devices.
Austro-Prussian War of 1866, Landscape Archaeology of the Battlefield of Sadowa-Königgrätz
Authors: Holas Matouš
Published: January 2024

The article attempts to present current results of landscape archaeology concerning a military conflict between Prussia and Austria in the summer of 1866 near Hradec Králové (Sadowa/Königgrätz). The aim is to introduce the possibilities of analysing individual available sources using the methods of battlefield archaeology, which is a sub-discipline of post-medieval archaeology. The historical period in question is not only a regional issue. This topic is mainly important with regard to protection of constantly endangered war relics, whose number in East Bohemia has been increasing in the past decade. The knowledge acquired from systematic and rescue excavations conducted in various parts of battlefields in the territory of Hradec Králové region demands new analysis to be appropriately evaluated and interpreted. The primary processing and treatment of finds are equally important as their spatial information and a successful setting into the chronological frame of well-known historical events. Archaeological knowledge thus sheds a new light on these events. The paper presents basic research topics and methods, to which increased attention is currently being paid within the context of archaeological sites. All of them use a wider view of the 1866 historical landscape, which was not distinctly modified for the purpose of military operations, but on the contrary significantly influenced their course and sequence. In order to properly interpret the acquired spatial data, it is necessary to reconstruct this historical landscape and to define the form of various activities which took place there during the war.

Sense of Belonging to War in Ukraine
Authors: Polek Tina
Published: January 2024

This reflection deals with the concept ‘sense of belonging’ in its relation to war in Ukraine. It shows the insiders’ perspective of this feeling and its role in everyday life behavior of Ukrainians. It raises up the problem of constructing a sense of belonging to war. What makes people feel the belonging? How collective experience creates collective belonging and how collective it actually is?

Reflection regards a sense of belonging on macro and micro level in its relation to solidarity from one side and in-group and out-group communication from the other side. The author also reflects about the ethics of belonging to war and appropriate and inappropriate behavior in this situation. The last part deals with the representation of a sense of belonging to war in verbal (what happens with language during the war?) and visual (in online and offline everyday life) form.
Collective Memory, Moral Economy and Land Disputes after the Repatriation of Crimean Tatars
Authors: Sobolieva Olena
Published: January 2024

This article is devoted to the meaning of identity and belonging in the processes of defending land rights. The 20th century was marked by unprecedentedly large processes of rejection and redistribution of land ownership in the countries of the socialist camp. Forced confiscation of property and collectivization fundamentally changed the landscape of land ownership. And in some border territories of the Soviet Union, which includes the Crimean peninsula, the events of ethnic deportations of the population had a decisive influence on the redistribution of land ownership as well. Separated from their ethnic lands, the Crimean Tatars formed an identity that had a clear connection to the lost territory and homeland. The process of political resistance, which continued during the Soviet period, and mass spontaneous repatriation took place under the main slogan - the restoration of justice and the return of Crimean Tatars to their ethnic homeland. After the return of a large part of the Crimean Tatars to their ethnic lands, the process of restoring land rights began. This process had an organized nature and great political resonance in Crimea and led to a significant reorganization of the cultural landscape of the peninsula.

Published: January 2024

Background: Little is known about the transgenerational effects of maternal exposure to fine particulate matter (PM2.5) on offspring kidney health. This study investigated the effect of maternal administration of PM2.5 or PM2.5 with vitamin D during pregnancy and lactation on renal injury in rat dams and their offspring. Methods: Nine pregnant Sprague-Dawley rats received oral administration of normal saline, airborne PM2.5, or PM2.5 with vitamin D from gestational day 11 to postpartum day 21. Kidneys of rat dams (n = 3 for each group) and their male offspring (n = 5 for each group) were taken for analysis on postpartum or postnatal day 21. Results: Maternal PM2.5 exposure increased glomerular damage, tubulointerstitial injury, and cortical macrophage infiltration in both dams and pups; all increases were attenuated by vitamin D administration. In dam kidneys, PM2.5 increased the protein expression of vitamin D receptor (VDR), klotho, and tumor necrosis factor-α; vitamin D lessened these changes. The expressions of renin, nuclear factor erythroid 2-related factor 2 (Nrf2), and nuclear factor-kappa B (NF-κB) p50 decreased in rat dams exposed to PM2.5. In offspring kidneys, exposure to maternal PM2.5 reduced the expression of VDR, renin, angiotensin-converting enzyme (ACE), Nrf2, and NF-κB p50, but increased cytochrome P450 24A1 expression. Maternal vitamin D administration with PM2.5 enhanced VDR, ACE, and NF-κB p50 activities in pup kidneys. Conclusion: PM2.5 exposure during nephrogenesis may exert transgenerational renal impairment, and maternal vitamin D intake could attenuate PM2.5-induced kidney damage in mothers and their offspring.
Can CSR engagement improve firm’s resilience to the COVID-19 pandemic? Evidence from the Moroccan stock market.
Authors:   Université Cadi Ayyad, Marrakech, Maroc, Ouchchikh Rachid , Ziky Mustapha , Laadimi Mohamed Taieb
Published: January 2024

The purpose of this paper is to investigate empirically the role of corporate social responsibility engagement on stock returns during the COVID-19 crisis in the case of a sample of Moroccan-listed companies. The authors use a difference-in-difference (DiD) regression estimated on a panel dataset of a sample of 23 Moroccan listed companies for the period spanning from March 2019 to March 2021. We identified the connection between CSR activities and financial returns by comparing the monthly stock returns of the treatment and the control groups. Empirical results reveal that the pandemic-induced decrease in stock returns is stronger for firms with CSR activities. It means that engaging in CSR activities does not immunize Moroccan firms during the pandemic. Our findings show that Moroccan’s stock market is unable to positively value CSR activities. The results indicate that agency problems lead Moroccan investors to overinvest in costly CSR activities, which reduce the value of the firms in times of the COVID crisis and delay their recovery from it. To the best of our knowledge, this study is the first to investigate the relationship between CSR activities and the resilience of Moroccan companies. Also, this study is distinguished by using the DiD method and by exploiting data from the Eikon Refinitiv database.

Authors:   Hassan II University of Casablanca, Morocco, El Yamani Rachida
Published: January 2024

Economic growth’s theories suggest that a developed financial sector can promote the economy growth. However, the ability of financial sector to boost the economic growth depends on its ability to finance the economy. This paper investigates the relationship between Morocco's economic growth and financial development (FD). We base our study on the crucial role of banking sector in economic growth in developing countries through their financial intermediation. In order, to verify this relationship the vector error correction model (VECM) is used on secondary data: real GDP per capita (GDP) and a set of explanatory variables representing the financial development sector, specifically the ratio of private sector credit (CPS) and control variables including the share of government consumption (PC), the real interest rate (IR), trade openness (TO), and the inflation rate (INF). Our secondary data comes from the Central Bank of Morocco database and covers 56 quarters from 2007Q1 to 2020Q4. The findings support the long- and short-term benefits of financial sector development for economic growth in Morocco.

As a maritime nation, fish is a staple in the Indonesian diet, rich in nutrition and a crucial protein source. It is imperative to maintain the freshness of fish to ensure the quality of fish production. However, the practice of mixing fresh and non-fresh fish poses a serious threat to consumer health and diminishes the overall quality of fish production. Therefore, the development of an automated and efficient method is necessary to distinguish between fresh and non-fresh fish. This research proposes the application of the Naïve Bayes method in classifying fish freshness based on color analysis in the eye area image. This approach involves the extraction of entropy features after segmenting fish images using the RGB and YCbCr color models. A total of 40 datasets of fish eye images were used for training and testing the model. The research results indicate that the proposed classification method achieved an accuracy rate of 97.5%. This success signifies the potential of the color analysis method and entropy features in distinguishing levels of fish freshness. These findings contribute to the development of automated techniques for monitoring and processing fish quality in the fisheries industry.

Authors: Fuad Moh. Fahimul , Mukri Moh. , Alamsyah A. , Akla A.
Published: January 2024

The term Islam Nusantara has sparked and caused polemics, pros, and cons that are quite warm in Indonesia since 2015 until now. As happened in the West Sumatra MUI environment. Islam Nusantara is interpreted as a religious pattern that exists in the archipelago, both at the level of religious practice and how to preach it. The level of amaliyah is interpreted as religious behavior that exists in the archipelago, especially in relation to fiqh which originates from its religious understanding. The problem is: What is the source of knowledge used in formulating Islamic fiqh in Nusantara? What is the validity and method of understanding the sources of knowledge used in formulating Islamic jurisprudence in Nusantara? How is the contribution of Islam Nusantara jurisprudence in reforming family law in Indonesia? This study aims to find answers to the epistemological formulation of Islamic jurisprudence in the archipelago and its contribution to reforming family law in Indonesia. To answer the questions above, the author uses qualitative research methods, types of literature research, the theory of ijtihad with the ushul fiqh approach. This means that the study of the concept of Islam Nusantara is carried out using the framework of ushul fiqh knowledge, especially regarding the concept of ijtihad. At the level of research work, the stretching of thinking to produce fiqh concepts that are unique to the archipelago is seen as part of ijtihad activities. The findings of the research are: (a) The source of knowledge used in formulating Islamic jurisprudence in the archipelago is a source of knowledge commonly known in the study of fiqh and ushul fiqh, both the mujma ’alaih and the mukhtalaf fih, (b) the source of knowledge as said to be valid. By giving a large enough portion to 'urf, and a benefit-oriented understanding, (c) Islam Nusantara’s fiqh can be used as an alternative law in the context of reforming family law in Indonesia.Keywords: Islam Nusantara, Jurisprudence, Epistemology, Legal Reform

It takes a process and cooperation between husband and wife and family members to make it happen, and it is not uncommon for households to contain various disputes with the end of divorce, especially during the current covid-19 pandemic, and to minimize this, the Tabliqh congregation of Lampung Province carries out the Masturah Program movement to prevent the increase in divorce cases in Lampung. This research is a qualitative research using an empirical juridical approach and is descriptive analytic, data analysis using inductive and deductive thinking frameworks. This study found the fact that the masturah program is very effectively used as a contemporary method to make it easier to create a sakinah family and as a renewable method as a means of mediation by the mediator so that religious courts and scholars are able to reduce divorce rates in Lampung province, especially among the Tabligh congregation community. Keywords:     Divorce Prevention, Masturah Program, Tabligh Congregation.
DIREITO À EDUCAÇÃO E SISTEMAS MUNICIPAIS DE ENSINO NA REGIÃO SUDESTE DO BRASIL: o que desvelam as pesquisas?
Authors: Brito Katia Cristina Custódio Ferreira , Conti Celso Luiz Aparecido , Nardim Thaise Luciane
Published: January 2024

Este artigo apresenta resultados de uma pesquisa que se debruçou sobre os trabalhos publicados em anais digitais de eventos científicos da Associação Nacional de Política e Administração da Educação (ANPAE) e do Grupo de Trabalho 5 da Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPED). O objetivo da pesquisa foi identificar trabalhos publicados nesses anais que abordassem temas relacionados à Educação Municipal, com ênfase no Sistema Municipal de Ensino, e sua relação com o direito à educação. Partindo de todos os anais digitais disponíveis publicamente, datados de 2010 a 2022, foram realizadas três rodadas de seleção, sendo uma delas por busca mecanizada e duas por leitura de varredura, tendo sidos selecionados 111 trabalhos. A análise pautou-se, ainda, na identificação dos grupos de pesquisa que desenvolvem estudos em torno do referido conteúdo. Identificou-se uma multiplicidade de textos que mencionam os termos descritores, cuja ênfase recai em temas que orbitam em torno dos sistemas municipais de ensino, havendo baixa ocorrência de produções que tomam este tema específico como objeto de reflexão e o compreendem como essencial para consolidação a garantia de direitos. O registro dos grupos de pesquisa no Diretório de Grupos corrobora essa observação, uma vez que os grupos do sudeste trazem a matéria apenas como palavras-chave de linhas de pesquisa. Conclui-se que as reflexões sobre o tema são pouco expressivas na produção analisada, indicando a necessidade de investigar-se o que condiciona esse fato.
