Dayaknese and Islam: A Confluence from Borneo's Hinterland, Indonesia
Authors: Amin Faizal , Tanggok M. Ikhsan
Published: October 2022

Sufism has generally been regarded as the confluence that helps to facilitate Islamization in Indonesia by opening accommodating spaces for local beliefs and practices. This article examines manuscripts as historical records to show concrete examples of how Sufi interpretations of local culture are constructed. This article is not only based on philological studies of the Abang Ahmad Tahir Manuscript Collections (MSS AAT), but also observations and interviews from the field between 2012 and 2019. This article argues that the MSS AAT have provided appropriate examples of the confluence of Dayakness and Islam. Not only has MSS AAT presented dynamic engagement between critically selected local traditions of cosmology and specific elements of Sufi textual discourses, but it has also noted the ways in which such texts further indicate both the Islamisation of local communities and how they vernacularise interpretations of Islam in Kapuas Hulu, which is situated in the hinterland of West Kalimantan
Al-Jihād al-insānī: Shumūlīyat "al-Muhammadīyah" fi muḥārabat ja'ihat COVID-19

Published: October 2022

The Covid-19 pandemic has jolted the world, including Indonesia. The transmission is extremely quick, huge, and difficult to identify. Millions of people have been infected, and some have died as a result. Vaccines and medicines that are effective have yet to be discovered. This extraordinary situation deserves exceptional handling from all sides. This research attempts to explain Muhammadiyah’s humanitarian jihad by mobilizing all of its resources using an empirical method and referencing the study of social fiqh-praxis. This study illustrates Muhammadiyah’s humanitarian struggle in sustaining and safeguarding life against the real threat of Covid-19. During the management of Covid-19, their efforts resulted in religious fatwas and humanitarian initiatives by involving all resources. The rise of this humanitarian struggle is the result of a genuine and unprecedented challenge to the soul and integrity of Muhammadiyah. This kind of jihad has ramifications for worship practices, activities, and organizational actions that include the public.
Social entrepreneurship in tourism: a chance for rural communities
Authors: Kulish Inna M.
Published: October 2022

The article argues that enterprises that develop the tourism sector in rural territorial communities have the characteristics of social enterprises and meet the threefold criterion – they ensure the well-being of residents of rural settlements. Ukrainian legislation gives local governments broad powers to plan and finance tourism activities, but their capacities are very limited as most rural budgets are subsidized. It is possible to promote tourism in rural communities only if the majority of residents are aware of all the benefits and responsibilities associated with this activity. The article confirms that uncontrolled exploitation of natural resources can lead to their irreversible depletion. The example of ski resorts shows that the practice of a single economic activity for the whole area poses a threat to local communities, as the well-being of residents becomes very dependent on natural and climatic conditions. The article emphasizes that the maximum use of available local resources is an important factor in the success of social entrepreneurship in tourism at the level of rural communities. In order to avoid conflicts when planning business, it is necessary to take into account the natural and anthropic resources of each community and compare the forms of their use with local values and traditions. Differences in the results of the impact on the local community as a result of the activities of the classic and social tourism enterprise on its territory are analyzed. The main vectors of the impact of social entrepreneurship in tourism on the social aspects of rural areas are highlighted.

Published: October 2022

Various approaches for the induction of moulting have been explained in the literature review, however, there is a dire need to explore other effective methods that can be more efficient in terms of production performance. The current study was conducted to evaluate the role of zinc-induced moulting on certain body performance attributes, serum biochemical profile and serum hormonal profile of White Leghorn layers towards the end of their first production cycle (spent layers). Commercial White Leghorn birds (n=24) of 67-weeks of age were procured from local market and were induced to moult with zinc oxide (3 g/kg diet) for three consecutive weeks. The spent layers were grouped as non-moulted group (NML) and moulted group (ML) after zinc-induced moulting. The result on overall body performance attributes indicated that the body weight and weight of organs significantly (P≤0.05) decreased in ML group birds as compared to the birds of NML group except for kidneys. The cholesterol, HDL, LDL and triglycerides were lower (P≤0.05) in birds of ML group as compared to birds of NML. On the contrary, serum circulating levels of ALT and AST were statistically higher (P≤0.05) in birds of ML group as compared to their counterpart NML group. A significant increase (P≤0.05) was noticed in serum T4 and cortisol concentrations for birds of ML group as compared to those of NML group, whereas T3 level was found decreased (P≤0.05) in birds of ML group. The results of present study indicated that usage of dietary supplementation of ZnO (3g/kg), for the purpose of moulting, exhibits promising effects on body performance attributes and serum biomarkers. Different dietary concentrations of ZnO may be evaluated in future to minimize stress and further enhance the performance of spent layers.

The absorption of the minerals produced by the probiotics in ruminants is expected to improve the absorption of the required nutrients. The study used different dietary rations with different percentage of concentrates: forages, different selenium doses, different locations and different strains of lactic acid bacteria as probiotics. The trials were performed with three repetitions using a factorial block (2x2x3x4). Samples were incubated for 48 h using in vitro incubation system. The parameters were pH, the kinetics of gas production, in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), and NH3-N concentration. The data were analyzed using the ANOVA, followed by the Duncan test. The results showed altered fermentation characteristics, while BioNano-Se at 25 ppm has significantly increased the rumen pH, gas production rate, IVDMD, IVOMD and decreased the total gas production significantly, but did not affect the ammonia concentration. High concentrate rations (R1) produces significantly lower pH (P < 0.05), but higher gas production rate and digestibility (P < 0.05). Higher dose of BioNano-Se significantly decreased gas production rate and ammonia production (P < 0.05). In conclusion, BioNano-Se and probiotics can alter rumen fermentation process.

Authors: Abedullah A , Kouser S , Badar H , Ibrahim M.N.M.
Published: October 2022

Aflatoxins are highly toxic compounds in raw milk and pose serious risks to human health. Growing awareness among consumers about safe food is encouraging researchers, suppliers, and policymakers to investigate consumers’ demand for aflatoxin-free raw milk. In this background, this study estimates consumers’ willingness to pay for varying levels of aflatoxin in raw milk in Pakistan. A discrete choice experiment was conducted on 360 randomly selected urban households in the Punjab province. We employed the latent class multinomial logit model to uncover the heterogeneity in consumers’ preferences for different quality and safety attributes of raw milk. Empirical findings suggest that consumers want to pay the highest premium of US$ 1.9/liter for milk having the lowest concentration of aflatoxin. Based on these findings, we suggest that there is considerable scope for the rapid development of aflatoxin-free milk in Pakistan, even though it is marketed at higher prices than the prices of status-quo milk.

Authors: Munir N , Samad S , Sharif N , Haq R , Naz S
Published: October 2022

Chemical and physical mutagens like sodium azide, H2O2 and UV light have a significant role in the metabolism of living organisms. Effect of these mutagens was recorded during the present work on lipid content of Oscillatoria sp. and Ulothrix sp. The algal species were subjected to the mutagens by adding them in culture media. Lipids were extracted by Microwave- assisted extraction using methanol, ethanol and chloroform. During the present work generally a significant effect of algal species and mutagens was observed. All the tested mutagen significantly affected the lipid content. A significant effect of solvent on lipid content of algal species was observed when the algae were extracted with different solvents after treatment with H2O2 and UV light however this effect was non-significant when algae were subjected to sodium azide. . In general, the mutagen resulted in an increase in lipid content. In Oscillatoria sp. the lipid content was generally less as compared to Ulothrix sp. The highest lipid content of 0.5433±0.002 g100g-1 was recorded in Ulothrix sp. after 3 days stress of sodium azide stress followed by H2O2 treated (50mM) samples with a content of 0.5133±0.05g100g-1. In Oscillatoria sp. 15mM treatment for 3 days gave a lipid content of 0.3733±0.0001g100g-1 after 3 days. A reduction in fresh weights of both tested algal species was recorded after UV stress. The oil content also showed a significant reduction after UV exposure. GC-MS analysis of the transesterified lipids showed that different fatty acids show variation when algal samples were treated with mutagens. Hence this study is helpful in manipulation of algal oil for biodiesel production.

The experiment was conducted to evaluate the metabolic activity through MTT (3[4,5-dimethylthiazol-2-y1]-2,5-diphenyltetrazolium bromide) reduction assay of Indian red jungle fowl sperm during cryopreservation process. In addition, MTT test was compared with sperm motility and viability data. Sperm analysis was made at pre-dilution, post-dilution, post-cooling, post-equilibration and post freeze-thawing stages. Pearson’s correlation coefficient showed significant (P<0.01) positive association of MTT reduction rate with motility (r=0.85) and viability (r=0.84). A significant (P<0.05) decline was observed in motility, viability and metabolic status after each stage of cryopreservation. The highest (P<0.05) stage-specific percent decrease in motility and viability were observed after freeze-thawing. Nevertheless, stage-specific percent decrease in metabolic status differ (P<0.05) after dilution (5.93 ± 0.12), cooling (8.41 ± 0.03), equilibration (19.1 ± 0.04) and freeze-thawing (30.9 ± 0.08). The total decrease in motility, viability and metabolic activity after the complete freeze-thawing cycle were calculated as 56%, 47% and 52%, respectively. It is concluded that MTT reduction assay is simple and reliable method to evaluate mitochondrial redox activity in sperm of this threatened species.

Since the emergence of Covid in Indonesia, the education sector in Indonesia has experienced changes in learning activities. This makes the ministry think of various efforts so that learning activities can still be carried out and teachers think of a learning model that can help students achieve their goals optimally. The research was conducted for fifth graders at El Fitra Elementary School which aims to determine the implementation of the Radec learning model with distance learning for students. The results of this study indicate that the Radec model has a good effect on helping students learn in online learning. This can be seen from being active and students being able to explain answers to pre-learning questions. However, in distance learning, there are still students who do not heed the teacher's instructions to read and are actively involved in learning.
Pernikahan Beda Agama: Tafsir Ideologis Ezra 10: 1-44 dengan Lensa Pluralisme Agama
Authors: Shindang Daniel Luther
Published: October 2022

In today's context, the level of religious intermarriage is increasingly questionable and negative. Even such negative imagery is legitimized by bible texts, for one thing: Ezra 10: 1-44. The text of Ezra 10: 1-44 explicitly shows Ezra's action against intermarriage between the Israelites and foreign nations. Such resistance is based on understanding that when the Israelites mix with foreigners their allegiance to YHWH is eroded. This post is the result of ideological criticism with a pluralism perspective on Ezra 10: 1-44. Interpretations reveal that the prevailing ideology that represented Ezra 10: 1-44 was the attempt to maintain the purity of the cult YHWH. Thus, the writer finds it necessary to do a dialectic with the problem of religious interfaith that takes place in today's context. The dialectic done was to find a correlation between the context of Ezra and current readers. On the other hand, based on the ideological theories of sheila brigs and Robert Setio, the writer offers a counter-ideology, producing a theological offer in the plural context of Indonesia.

This article aims to interpret Psalm 80 and explore its implications. Restoring power is derived from the original national spirituality. Every nation, in any civilization, has national spirituality that was born from the noble promise when the nation was formed. The noble commitment is a manifestation of the work and role of the Holy Spirit, who gave wisdom to the nation's founders with one goal: to build a country that unites its pluralistic people and fights for prosperity, justice, truth, and integrity for its pluralistic people equally. With a socio-exegetic approach, the author asserts that the practice of restoring power is a manifestation of God's authority in the nation.

Bei dynamischen Messungen an Eisenbahnbrücken zur Bestimmung des Lehr’schen Dämpfungsmaßes haben nicht nur die angewendeten Mess- und Auswertemethoden einen Einfluss auf die Ergebnisstreuung der versuchstechnisch ermittelten Dämpfungsmaße, sondern auch die versuchsauswertende Person. Diese Umstände verdeutlichen den Bedarf nach der Festlegung einer einheitlichen Vorgehensweise bei der Auswertung von dynamischen Versuchen, um einerseits die Ergebnisstreuung zu reduzieren und andererseits um den individuellen Handlungsspielraum der auswertenden Person einzuschränken, damit auch eine objektive Vergleichbarkeit unterschiedlicher Messungen am selben Objekt gegeben werden kann. In Teil 1 zum vorliegenden Beitrag wurden Methoden und Analysewerkzeuge für Messungen im Frequenzbereich vorgestellt. Der vorliegende Teil 2 behandelt Methoden im Zeitbereich, wobei das Ausschwingverhalten des Tragwerkes nach dynamischer Anregung die Grundlage bildet. Die praktische Anwendung der in diesem Beitrag vorgestellten Methoden und Analysewerkzeuge sowie die formulierte Handlungsweise zur Festlegung eines konkreten Lehr’schen Dämpfungsmaßes wird dabei anhand eines In-situ-Versuches exemplarisch dargelegt.

Published: October 2022

Fusicoccane-type terpenoids are a subgroup of diterpenoids featured with a unique 5-8-5 ring system. They are widely distributed in nature and possess a variety of biological activities. Up to date, only five fusicoccane-type diterpene synthases have been identified. Here, we identify a two-gene biosynthetic gene cluster containing a new fusicoccane-type diterpene synthase gene tadA and an associated cytochrome P450 gene tadB from Talaromyces wortmannii ATCC 26942. Heterologous expression reveals that TadA catalyzes the formation of a new fusicoccane-type diterpene talaro-7,13-diene. D2O isotope labeling combined with site-directed mutagenesis indicates that TadA might employ a different C2,6 cyclization strategy from the known fusicoccane-type diterpene synthases, in which a neutral intermediate is firstly formed and then protonated by an environmental proton. In addition, we demonstrate that the associated cytochrome P450 enzyme TadB is able to catalyze multiple oxidation of talaro-7,13-diene to yield talaro-6,13-dien-5,8-dione.

Chitosan is a polymeric material having properties such as adsorption and hydrophilicity. Chitosan itself is almost photocatalytically inactive, but it can couple with other photocatalysts to improve their photocatalytic activity. Chitosan significantly enhances photocatalysts' adsorption and lowers the charge carrier recombination, which ultimately aids in the enhanced photocatalytic activity. In this review, we have discussed chitosan's basic structural, electronic, and chemical properties. We have also explored the photocatalytic properties of chitosan and chitosan-based materials. Since metal-based and metal-free semiconductors are the two major classes of semiconductor photocatalysts, so we have described how chitosan can be used to enhance the limitations of metal-based and metal-free semiconductor photocatalysts. This review will help to develop a better understanding of chitosan and chitosan-based materials for photocatalysis. We have also explored the future aspects of chitosan-based photocatalytic materials to improve the research in the future.

e-mail: yuliia.stetsiv@lnu.edu.ua Polyaniline (PAn) films, doped with citric acid, were synthesized on a polyethylene substrate by chemical oxidative polymerization using ammonium peroxydisulfate as an oxidant. The influence of monomer concentration on the optical properties of PAn films was investigated. Optical band gap, absorption coefficient, extinction coefficient, refractive index were calculated as a function of wavelength. Different methods for determining the energy of the energy gap (Tauc method and absorption spectrum fitting) were considered. It was found that the optical band gap for all thin PAn films is due to the direct allowed optical transitions. It was found that the band gap of PAn films decreases with increasing thickness of deposited PAn films. It is established that the optical energies of the band gap of PAn films of different thickness, estimated by the results of optical absorption measurements using Tauc methods and absorption spectrum fitting, are practically commensurate and are in the range of 3.13–2.36 eV for film thicknesses equal to 18.7–137.4 nm, respectively. Based on the correlations between the optical energy of the band gap and the refractive index of semiconductors using Moss, Ravindra, Ravindra-Gupta, Reddy-Ahammed, Gerve-Vandamme, Kumar-Singh, Annani and Duffy-Reddy ratios, the value of the refractive index of PAn films was calculated and these results were compared with the values obtained from the experimental results. From the obtained results it is seen that the refractive index of PAn films increases with increasing polyaniline film thickness on a polyethylene substrate. The values obtained from the Ravindra and Ravindra-Gupta relations are the closest to the experimental ones. Therefore, the synthesized PE/PAn films can be an available material for the production of optoelectronic devices, for example, for organic field transistors and LEDs.

Providing macroscopic magnetism in organic materials is a very complex but quite promising scientific problem. The need to create an organic magnet is due to a number of expected advantages, such as lightness, transparency, flexibility, ability to switch under the influence of light (magneto-optics), or chemical influences (sensors), creation of modern toners for digital printing, materials for chemical power sources etc. To understand the mechanism of biological processes, in particular, human thinking and DNA functioning may help to study the state of spin glass, biomagnetism, the mechanism of action of paramagnetic probes in living tissues and others. In the present paper the peculiarities of the structure and magnetic behavior of the iron complex with 1-nitroso-2-naphthol Na[Fe(C10H6(NO2)3] have been studied. The powder X-ray diffraction method determined that the crystal structure of the complex is monoclinic with the space group P2/1. According to cyclic voltammetry, the electrochemical behavior of the complex anion Fe(C10H6(NO2)3] is characteristic of reversible electrochemical systems with one electron transfer. Optical absorption bands are observed in the electronic spectra of the complex at 389, 690, and 763 nm. The dependences of the magnetic susceptibility of the complex on the temperature, frequency and magnetic field strength in the temperature range 1.5–200 K in the external magnetic field up to 90 kE and in the frequency range from 95 to 2000 Hz are obtained and analyzed. At low temperatures, the peculiarities of magnetic behavior characteristic of the state of spin glass are revealed. The EPR spectrum of the complex is a superposition of two lines, the behavior of which is opposite when the temperature changes in the range of 4–293 K, which indicates the unusual dynamics of the molecular surrounding the Fe3+ ion. Such features may be due to the presence of two structurally inhomogeneous magnetic centers that exhibit opposite spin dynamics with changing temperature. The presence of this dynamic can have a significant impact on the properties of the substance.

For the first time, the crystal structures of new quaternary compounds were studied by the powder method. They crystallize in tetragonal system, Sp.Gr. I-4, structural type CuIn2Te3Cl, with cell parameters: AgGa2Se3Cl (a = 5.9789(3) Å, c = 10.8592(7) Å), AgGa2Se3Br (a = 5.9767(3) Å, c = 10.8558(7) Å). From the analysis of the crystal structure it was found that the researched quaternary compounds belong to semiconductors with the general formula AІВІІІ2XVI3YVII (AІ – Cu, Ag; ВІІІ – Ga, In; XVI – S, Se; YVII  Cl, Br, I). Chalcohalide compounds of the АІСІІІ2XVI3YVIІ type refers to cation-defective compounds with a ratio of cations to anions 3:4. Their compositions can be represented by the formula Kn-uuAn, where K cations,  vacancies, A anions, u the first letter of the word unoccupied. For these compounds VEC = 4,571. If we consider the vacancy as an atom with zero valence, we get for compounds АІСІІІ2XVI3YVIІ VEC = 4. This structure refers to the tetrahedrals when the cations are surrounded by the four nearest anions. This is confirmed by the studied crystal structures of the compounds AgGa2Se3Cl(Br). The semiconductor properties can be expected from these and other compounds from the group AІВІІІ2XVI3YVII (AІ – Cu, Ag; ВІІІ – Ga, In; XVI – S, Se; YVII  Cl, Br, I).

The imidazo[2,1-b][1,3]thiazine nucleus, as well as the pyridine-N-oxide fragment, are pharmacophore groups that have received much attention from researchers. That is why the combination of these scaffolds in the structure of a single molecule seems to be quite attractive from chemical and biological point of view. Synthetically available 4-pyridinyloxy-substituted (benzo)imidazo[2,1-b]thiazines were used as precursors to obtain previously unknown (benzo)imidazo[2,1-b][1,3]thiazin-6-yloxypyridine 1-oxides. It was found that the oxidation of the latter with m-chlorobenzoic acid under mild reaction conditions using dichloromethane as a solvent at room temperature proceeds smoothly and selectively to obtain only the target products. The composition and structure of the synthesized pyridine-N-oxides are unambiguously confirmed by complex physicochemical analysis, particularly by 1H and 13C NMR spectroscopy, chromato-mass spectrometry, as well as elemental analysis data. The antiexudative activity of (benz)imidazo[2,1-b][1,3]thiazin-6-yloxypyridine 1-oxides was studied in vivo in a model of carrageenan-induced paw edema in white outbred male rats. The development of edema was considered from increasing the volume of the paw 4 hours after the introduction of carrageenan. Quantitative assessment of antiexudative activity was performed by the degree of reduction of rat paw edema, and the rate of suppression of the inflammatory process was calculated. Performed bioscreening showed that the synthesized pyridine-N-oxides are characterized by weak anti-inflammatory activity, and only 2-chloro-4-[(2,3-diphenyl-6,7-dihydro-5H-imidazo[2,1-b][1,3]thiazin-6-yl)oxy]pyridine 1-oxide 2a has moderate antiexudative effect with of inflammatory inhibition rate of 31.9%. This compound is thus of interest for further structural modification in order to obtain potential non-steroidal anti-inflammatory agents. It is important to note that the presence in the structure of the synthesized derivatives 2a-e of N-oxide fragment is very promising for the design of anti-inflammatory agents, which are characterized by the absence of side effects caused by inhibition of cyclooxygenase-1.
