Undang-undang Perbankan mengatur bahwa eksekusi agunan dapat dilakukan dengan dua cara yaitu yaitu melalui pelelangan atau secara di bawah tangan. Dalam praktik, penjualan melalui pelelangan tidak selalu berhasil dengan cepat. Bank kemudian melakukan langkah pengambilalihan agunan yaitu dengan cara membeli melalui lelang (AYDA). AYDA atas pengalihan tanah dan/atau bangunan akan menimbulkan kewajiban perpajakan bagi bank berupa BPHTB. Dalam UU Perbankan, kewajiban bank sebagai pembeli dapat ditunda dalam jangka waktu 1 (satu) tahun sampai bank menemukan pembeli AYDA. Tulisan ini mengkaji pemenuhan kewajiban BPHTB dalam pengambilalihan agunan tanah dan/atau bangunan oleh bank melalui lelang dan kepastian hukum penundaan kewajiban BPHTB-nya dalam perspektif Hukum Perbankan dan UU HKPD. Metode Penelitian yang digunakan adalah yuridis normatif dengan cara mengkaji permasalahan berdasarkan bahan-bahan kepustakaan. Penelitian ini menggunakan pendekatan undang-undang dan pendekatan konseptual dengan spesifikasi penelitian deskriptif analitis dan cara analisis data yuridis kualitatif. Berdasarkan hasil penelitian dapat disimpulkan menurut UU HKPD, pemenuhan BPHTB terutang harus dibayar oleh pemenang lelang pada saat penunjukan pemenang lelang yaitu tanggal pelaksanaan lelang. Sedangkan menurut UU Perbankan, kewajiban BPHTB tersebut dapat ditangguhkan selama 1 (satu) tahun. Dualisme pengaturan tersebut menimbulkan penafsiran yang berbeda dalam penerapannya. Adapun cara yang dapat dilakukan untuk mengatasinya dengan melakukan penafsiran dan perbaikan regulasi. Perbaikan dilakukan dengan merevisi UU HKPD terkait saat terutangnya BPHTB dan ketentuan pengecualian bagi bank terkait pembayaran BPHTB atas AYDA oleh bank melalui lelang. Selain itu, amanat UU Perbankan untuk membuat Peraturan Pemerintah yang mengatur tata cara pembelian agunan dan pencairannya perlu direalisasikan.

Authors: Rebai Rania , Iman Sebai
Published: July 2023

The COVID-19 pandemic has overwhelmed healthcare systems particularly the training curriculum for post-graduate medical students. Our aim was to assess family medicine residents’ perceived impact of the COVID-19 pandemic on training and medical education in Tunisia. Methods: We conducted a cross-sectional survey among all Tunisian family medicine residents who were in training during the year 2020. Residents starting their first-year residency studies in 2021 were excluded. A structured questionnaire was created and shared via Google Forms. Residents' anonymity and consent were respected. Results: We included 107 residents (85% females). During the first semester of 2020, a significant reduction in workload was reported including working hours (58.9%), patient's flow (65.1%) and elective admission (83%). The workload tended to partially normalize during the second half of the year. The restriction of academic activities (staff, grand rounds, and congresses) was considered the major obstacle (73.8%) hindering residents’ training. About 72% benefited from E-learning during the second period. By the end of 2020, 48.6% of participants reported being infected by the virus. The majority (97.2%) reported feeling anxious, irritable and/or depressed. The pandemic significantly decreased residents' satisfaction with their medical training (4.22±2.15 before the crisis versus 2.78±1.18 during COVID-19) (p<10-3). Conclusion: The COVID-19 pandemic had decreased residents' level of satisfaction with their training and had negatively affected their mental health. The key findings of the present research can be a starting point to provide high quality residency training and to avoid bypassing their weaknesses in the upcoming outbreaks.
Pasar 16 Ilir: Ruang Perdagangan di Kota Palembang Awal Abad 20
Authors: Wargadalem Farida R. , Susanti Helen
Published: July 2023

This research is based on the lack of narrative regarding the market as an important space for trade in the Palembang City area. In fact, the market is one of the most important trading spaces in the transaction process, meeting sellers and buyers, and cultural exchange. Palembang as a trading city has a fairly well-known market, especially during the Dutch colonial period, namely the Pasar 16 Ilir Palembang area. Merchants from various ethnic backgrounds trade at Pasar 16 Ilir, such as: Local traders from the Archipelago, Arabs, India, China, to Europe. This study aims to reveal the role of Pasar 16 Ilir as a trading space in the Palembang region. This research uses historical methods by utilizing a variety of literature, such as: archives, journals, and books. The results of this study indicate that the Pasar 16 Ilir area began to form in 1900 (early 20th century). The market became lively and growing because of its strategic location on the outskirts of the Musi River and the development being carried out by the colonialists. New, more modern stalls were built to replace the old booths by paying attention to hygienic aspects. Apart from that, the bustling market was also caused by an increase in trading commodities. The increasing number of buyers and the large number of commodities being traded are the impact of the enactment of the 1870 Agrarian Law. In its development, Pasar 16 has not only become a meeting point for traders and buyers from various social and ethnic backgrounds. More than that, there has been social interaction that has an influence, especially on the socio-economic.

The main problem studied in this research is how to manage women's education to the realization of educational outcomes in women's schools formed by Sultan Syarif Kasim II in 1927-1945. In general, this study aims to describe the pattern of women's education formed by Sultan Syarif Kasim II and his consort in the Siak Sultanate. This study was studied by applying historical methods, including four steps, namely heuristics, verification, interpretation, and historiography. Based on the research findings, the pattern of women's education in Siak Sri Indrapura was formed directly by the sultanate including the formation of the curriculum, procurement of teachers and students and the facilities provided. Although both were managed by the sultanate, there were different styles of teaching between the two women's schools founded by Sultan Syarif Kasim II, namely Sultanah Latifah School which focused more on teaching hand skills and homemaking, and Madrasa Annisa which taught more Islamic religious knowledge. The results of the education of the two girls' schools gave birth to women who were prosperous in terms of changes in social institutions, which succeeded in becoming a weaver, educator, and preacher. Thus the management of education formed by Sultan Syarif Kasim II succeeded in contributing greatly to the welfare of women's education in the Sultanate of Siak Sri Indrapura

Human capital convergence in European NUTS 2 regions
Authors: Dańska-Borsiak Barbara
Published: July 2023

Research background: The role of human capital in modern economy development is as important as that of material growth factors. According to the three-sector model theory, economic growth is associated with the process of labour force leaving the primary sector. The research issue addressed in this paper was the human capital level estimation in European NUTS 2 regions and the relationship between the human capital level and sectoral structure of the economy.
Purpose of the article: The article aimed to verify the hypotheses of absolute and conditional human capital convergence in European NUTS 2 regions. The analysis covered the 2005-2020 period for European NUTS 2 regions and two subgroups: the CEE regions and the Western European regions.
Methods: A composite indicator approach was adopted to measure human capital levels in NUTS 2 regions. In order to verify the absolute and conditional b-convergence hypotheses, dynamic panel data models were estimated. The Blundell and Bond system-GMM estimator with parameter standard errors robust to heteroscedasticity was used.
Findings & value added: The study positively verified the hypotheses of absolute and conditional convergence in each group of regions. Percentages of employees in sectors proved to be the steady-state determinants. The time needed to reduce differences occurring in human capital levels by half (a half-life) was about 11 times greater for the CEE regions than for the Western European ones. The value added of the article lies in proving the relationship between the sectoral structure of employees and the pace of human capital convergence in European NUTS 2 regions.

DONORS AND DONATIONS IN SIXTEENTH-CENTURY WALLACHIA AND MOLDAVIA
Authors: SULLIVAN Alice Isabella
Published: July 2023

In the post-Byzantine period, the rulers of the north-Danubian principalities of Wallachia and Moldavia, through their monetary gifts and donations, played central roles in the continuation of religious life within and beyond the borders of their domains. This essay charts the patterns of patronage of two key donors – Neagoe Basarab of Wallachia (r. 1512–1521) and Peter Rareș of Moldavia (r. 1527–1528; 1541–1546) – in order to underscore their piety and the broader implications of their activities. Through the extant textual and material evidence, this study engages with aspects of the desires, collaborations, and effects of patronage from these two important rulers within Wallachia and Moldavia, respectively, and to far-off places like Mount Athos and the monastery of Saint Catherine at Mount Sinai. This study reveals a complex web of personal, spiritual, and ideological facets of leadership and identity that shaped a culture of donations and piety rooted in Byzantine models and transformed in local contexts through the desires and ambitions of each individual ruler.
A BRIEF HISTORIOGRAPHICAL NOTE RELATED TO NORTH ASIA: NICOLAE MILESCU (1636–1708) & JOHN FREDERICK BADDELEY (1854–1939)
Authors: DUMBRAVĂ Daniela
Published: July 2023

Russian exploration in the 17th century attracted the attention of twentieth-century geographers, a fact that also resulted in a series of translations of texts produced by Russian embassies in the Far East, especially those beginning to deal with the Qing dynasty. The British geographer John F. Baddeley was one of these geographers, as he was also a member of the Royal Geographical Society. He not only translated texts, but also explored the Russian territories under discussion using the corpus of manuscripts compiled by the Russian ambassador to the Qing, Nicolae Milescu. The reception of his translations and his venture into North Asia by historians of science and geographers is remarkable, and it is equally a nuance where the history of the 17th century seems to ‘encounter’ Baddeley’s time of exploration in the 20th century.
“GOD PREPARES THE WAY FOR HIS LIGHT TO ENTER INTO THE TERRIBLE DARKNESS OF MUSCOVY”. EXCHANGE AND MOBILITY BETWEEN HALLE PIETISM AND RUSSIAN ORTHODOX CLERGY IN THE 18TH CENTURY
Authors: HAAS Daniel , LYUTKO Eugene , RIMESTAD Sebastian
Published: July 2023

This contribution analyses the relationship between Halle Pietism and Russian Orthodoxy with a focus on the mobility of actors on both sides. This included Halle Pietists travelling to Russia, but also young Russians being invited to Halle to study theology. The paper uses unpublished sources from the Archives of the Francke Foundations in Halle to paint a comprehensive picture of this mobility of people, but also of ideas and literature, which might not have achieved the intended aims on either side, but was still an important episode in German-Russian relations that has received very little attention in existing research. The relationship is looked at over four distinct chronological stages from the final decade of the 17th century to the Catherinian era in the 1760s, with an additional section focusing on the Russian academic migration to Halle. Each of these stages must be seen both within the context of what happened in Russia at this time, as well as the developments in Halle. This paper takes all these aspects into account.
EXPLORING GENDER DIFFERENCES IN USING METADISCOURSE FOR POLITICAL OPINION WRITING
Authors: Ramash Nur Syahira , Ng Lay Shi
Published: July 2023

Background and Purpose: Metadiscourse marker is one of the most commonly-used linguistic devices in persuasive writing, and it shapes writer’s arguments to the needs and expectations of the target readers. Research has consistently shown that women, on average, are less politically interested, informed, and efficacious than men. However, this does not necessarily imply that male columnists are more persuasive than female columnists when writing political opinion articles. Hence, the present study aims to investigate how male and female columnists use metadiscourse markers in political opinion writing to effectively direct their political views toward their readers.
 
Methodology: This descriptive study used frequency analysis, comparative analysis, and a semi-structured interview with eight ardent readers to examine metadiscourse markers used by male and female columnists in their political opinion articles, as well as the impact of persuasion on their readers. 100 opinion articles about Malaysia's 14th general election were chosen from two English-language online newspaper portals in Malaysia, The Star and the New Straits Times.
 
Findings: The findings revealed that female columnists employed more metadiscourse markers than male columnists. Respondents concluded that articles with more metadiscourse markers used in the text, particularly in the interpersonal category, appeared to be more persuasive. Furthermore, the findings indicated that female columnists presented a more convincing image than those produced by male columnists.
 
Contributions: As research conducted on gender differences in political writing is still rare, this research provided information regarding gender preferences in using metadiscourse markers in political opinion articles. This study contributes to the body of knowledge by informing researchers and opinion writers about the many types of metadiscourse markers that may be used to establish rapport between writers and readers.
 
Keywords: Metadiscourse markers, persuasive writing, gender, male, female, political-opinion articles.

THE EFFECT OF BLENDED LEARNING TOWARDS PUPILS’ VOCABULARY DEVELOPMENT AND MOTIVATION IN AN ESL CLASSROOM
Authors: Hong Andy Lim Teik , Stapa Mahani
Published: July 2023

Background and Purpose: Vocabulary is the fundamental aspect of a language. However, second language (L2) learners often perceive vocabulary learning as boring and difficult. As such, various efforts must be made by teachers to empower pupils’ vocabulary base to be able to be competent in the target language. Hence, this study attempts to address the use of blended learning on pupils’ vocabulary development and motivation.
 
Methodology: This research adopted the quantitative research design. The research participants consisted of two classes of primary school pupils chosen through purposive sampling. The pupils were divided into the experimental group and the control group. The instruments used were pre-test, post-test, and questionnaires. An independent t-test was used to compare the mean score to see any significant difference in terms of pupils’ pre-test and post-test scores whereas mean interpretation was used to determine pupils’ level of motivation.
 
Findings: The results revealed that pupils who learned through blended learning performed better in terms of vocabulary development compared to the pupils who learned through traditional learning. Similarly, pupils have high motivation towards blended learning instructions. It is apparent that pupils become motivated learners when their need for autonomy, competence, and relatedness are fulfilled.
 
Contributions: This research aids teachers in constructing suitable blended learning environments for content delivery as an alternative way for students to interact with information in preparation for classroom work.
Keywords: Blended learning, vocabulary development, motivation, ESL classroom, purposive sampling.

In the nanotechnology era, nanotechnology applications have been intensifying their prospects to embrace all the vigorous sectors persuading human health and animal. The safety and concerns regarding the widespread use of engineered nanomaterials (NMs) and their potential effect on human health still require further clarification. Literature elucidated that NMs exhibited significant adverse effects on various molecular and cellular alterations. Epigenetics is a complex process resulting in the interactions between an organism’s environment and genome. The epigenetic modifications, including histone modification and DNA methylation, chromatin structure and DNA accessibility alteration, regulate gene expression patterns. Disturbances of epigenetic markers induced by NMs might promote the sensitivity of humans and animals to several diseases. Also, this paper focuses on the epigenetic regulators of some dietary nutrients that have been confirmed to stimulate the epigenome and, more exactly, DNA histone modifications and non-histone proteins modulation by acetylation, and phosphorylation inhibition, which counteracts oxidative stress generations. The present review epitomizes the recent evidence of the potential effects of NMs on histone modifications, in addition to in vivo and in vitro cytosine DNA methylation and its toxicity. Furthermore, the part of epigenetic fluctuations as possible translational biomarkers for uncovering untoward properties of NMs is deliberated.

Published: July 2023

In a fruit crop located in the Lujan district (Buenos Aires province, Argentina), we exposed plastic bottles to the environment for three years. We explored microplastics’ presence on thalli. Out of the potential five lichen species only one grew: Hyperphyscia coralloides. Microplastic particles were observed on the thalli. The present work represents the first record of H. coralloides growing on PET plastic. Considering the largest thalli size recorded, the results of the growth rate are similar in an average to those recorded for fruticose species. Finally, our results suggest that the contact of H. coralloides with microplastics may be a potential pathway for the incorporation of microplastics into ecosystems.
Does Digitalization Accelerate the Winner-Takes-All Effect in the Sports Industry?
Authors: Glebova Ekaterina , Terrien Mickaël , Desbordes Michel
Published: July 2023

Today media and sports are indivisible, having a kind of inseparable, mutually influential relationship. Media attracts audiences and generates profit through sports. In its turn, sports content is disseminated, transmitted, and popularized through the media. Thus, theoretically, sports and media exist in symbiosis. However, practically, this relationship is complex and includes many factors. First of all, in recent decades, the process of overall digitalization (and digital transformation) of all fields of life has had a crucial impact on sport, media, and their interrelationship. This paper aims to conceptualize and analyze the possible impact of digitalization on “winner-takes-all” (WTA) (winner-takes-most, WTM) dynamics in the professional sports industry, notably for spectating audiences, and answer the question: “Can digitalization be seen as a driver of ecosystem change and how it should be tested?” This conceptual model paper seeks to construct and develop a theoretical framework that can explain and predict relationships between concepts of digitalization and key sport spectating variables: audience, TV rights, and revenue through a prism of WTA. We found that the technological change in the sports media market and the greater global-orientated strategy of leading sports organizations have re-sorted and compressed many market shares, but the effect of technological disruption has been significantly less pronounced for the most powerful digital leaders in the industry. To this end, we represent digitalization as the main accelerating factor of the WTA effect (along with other auxiliary effects) in the sports industry and propose future research directions and perspectives.

Published: July 2023

The increased global demand for and price of rare earth elements (REEs) has led to intensive search for them in rocks of the upper continental crust all over the world. This study is aimed at characterising the granitoids at Okeho within Southwestern Nigeria using geochemical data and assessing their potential for REE enrichment. Ten representative rock samples of the Proterozoic intrusives, syenite and granodiorite, were studied for their mineralogical and elemental compositions. Elemental concentrations were analysed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Average major oxide concentrations revealed SiO2 (57.53 wt. %), Al2O3 (13.25 wt. %), CaO (5.05 wt. %), and MgO (5.59 wt. %) for the syenite and SiO2 (62.39 wt. %), Al2O3 (14.98 wt. %), CaO (3.67 wt. %), and MgO (3.25 wt. %) for the granodiorite. Total Alkali–Silica (TAS), Aluminum Saturation Index (ASI), and La/10-Y/15-Nb/8 plots discriminated the granitoids as metaluminous monzonite-syenite and peraluminous diorite-granodiorite. Average total REE concentrations in the syenite (625.06 ppm) and porphyritic-granodiorite (364.51 ppm) were above values reported for the granites in some mines in Jiangxi Province, Southern China.

Tujuan penelitian ini adalah untuk mengetahui kemampuan larva T. molitor pada tingkatan instar 4, 6 dan 8 dalam mendegradasi limbah masker medis surgical yang dicampur ampas tahu dan dedak padi serta melihat pertambahan bobot badan larva. Penelitian ini dilakukan secara eksperimen  menggunakan Metode Rancangan Acak Lengkap Faktorial (RALF) dengan 3 perlakuan dan 3 kali penggulangan masing-masing instar. Hasil dari penelitian ini menunjukkan bahwa  Larva T. molitor pada instar 6 memiliki laju degradasi tertinggi yaitu 2,39 gr/hari dibandingkan instar 4 dan instar 8 dengan  pakan masker yang dicampur dengan ampas tahu (P1). Sedangkan untuk laju degradasi terendah yaitu pada instar 4 yaitu sebesar 0,01 gr/hari, dengan pakan masker tanpa dicampur limbah organik. Pemberian pakan kombinasi pada larva menyebabkan perubahan yang signifikan terhadap bobot badan larva. Hubungan pakan yang terdegradasi dengan pertambahan bobot badan pada instar 4 dikategorikan sedang yaitu memiliki nilai korelasi (r) = 0,579 gr/hari dan instar 6  dikategorikan sedang juga karena memiliki nilai korelasi (r) = 0,509 gr/hari,sedangkan  instar 8 memiliki korelasi (r) = 0,221 gr/hari dikatakan lemah dan tidak berpengaruh terhadap pertambahan bobot badan.

Published: July 2023

Biota laut seperti ikan, kerang, dan gastropoda lainnya merupakan sumber makanan bagi manusia. Pada Kawasan Teluk Benoa, nelayan umumnya menangkap biota tersebut dan menjualnya di pasar atau untuk dikonsumsi. Logam berat telah mencemari biota laut di sekitar Teluk Benoa. Logam berat memiliki efek fatal bagi tubuh manusia jika dikonsumsi secara berlebihan. Beberapa logam berat yang berbahaya seperti kadmium (Cd), kromium (Cr), tembaga (Cu), timbal (Pb), dan seng (Zn). Penelitian ini bertujuan untuk mengetahui konsentrasi logam berat Cd, Cr, Cu, Pb, dan Zn pada biota laut di sekitar Teluk Benoa. Sampel ikan, kerang, dan gastropoda diambil secara acak dari nelayan Teluk Benoa. Metode AAS (Atomic Absorption Spectrophotometry) digunakan untuk menentukan konsentrasi logam berat pada setiap objek. Hasil penelitian menunjukkan konsentrasi logam berat yang tinggi pada Scarus Psittacus (ikan kakatua), Acanthurus xanthophores (ikan madah), Marcia hiantina (kerang merah), Anadara antiquata (kerang darah), and Cerithidea sp. (siso/batu-batu). Perbandingan dengan baku mutu FAO (1983), WHO (1989), IAEA-407 (2003), dan SNI-7387 (2009) menunjukkan bahwa biota-biota tersebut telah melebihi baku mutu. Pencemaran logam berat dari sedimen laut di daerah yang sama dan cara makan biota menjadi indikator dari konsentrasi logam berat yang variasi pada biota tersebut.

Indonesia is one of the countries that have a fairly high level of consumption of fuel oil (BBM), based on data from BPH Migas (2018) throughout 2018 which reached 75 million kiloliters or an average of 1.6 million kiloliters per day. The consumption includes 16.2 million kiloliters of certain types of fuel (JBT), special types of fuel for assignment (JBKP), and general types of fuel around 51.3 kiloliters. The data is growing this study aims to measure the efficiency of reducing imports of fuel oil by utilizing solid waste of palm oil and to make proposals for the formulation of planning scenarios to optimize the functions of the Indonesian palm oil downstream industry. This research method combines quantitative and qualitative methods using the concept of efficiency and the Scenario Planning model. The method used in this paper is to calculate the level of efficiency using quantitative data on oil palm based on the amount of plantation area and the solid waste it produces. Then a mapping of the downstream palm oil industry will be carried out by reviewing the results of previous research as well as data and information obtained from accurate sources. The result is that by optimizing the utilization of palm oil solid waste, 7.4 billion liters of bioethanol can be obtained which can be used to produce biofuels to reduce the level of imports of fuel oil in Indonesia.

3D Printing Machine is a machine that works with the basic principle of CNC, namely the movement of the machine in making the workpiece which is regulated by the G code in 3 coordinate axes x, y, and z. Based on how it works, 3d printing machines are classified into 7, namely, Vat photopolymerization, Material Extrusion, Powder-Bed Fusion, Sheet Lamination, Binder Jetting, Material Jetting, Directed Energy Deposition. The results of the research on 3d Printing Material extrusion this time using PLA material with a machining diameter of 1.75mm, nozzle distance with bed 0.1mm, nozzle diameter 0.4mm, layer height 0.12mm, nozzle temperature 2000C, bed temperature 600C, printing speed 80mm/s. The experimental results found problems such as clogging, the filament does not stick to the bed, the filament has a different freezing point, thus affecting the geometry of the workpiece to be printed. For the mass of all printed workpieces after measuring the mass with no significant changes, it is ensured that the problem originates from variables related to the printing of each layer in the form of printing speed, bed temperature, nozzle temperature, and system temperature.

OBJECTIVE: To verify the adequacy of the tidal volume (VT) of the preterm newborn (PTNB) under mechanical ventilation according to the parameter adjustments made by the team and to compare it with the ideal tidal volume for the weight. METHOD: This is a cross-sectional study with a sample composed of PTNB with gestational age (GA) <37 weeks hospitalized in the Neonatal Intensive Care Unit of Hospital Agamenon Magalhães. Six VT measurements were collected for 60 seconds and the adequacy of the VT found was assessed by calculating the ideal tidal volume (VTi) using the formula Vti = 4ml / kg x current weight. RESULT: The sample of 16 premature infants, 68.7% had inadequate TV at the time of collection. PTNBs with GA above 30 weeks obtained a statistically higher TV (TV = 12.27 ± 2.22mL). When corrected for weight, those with GA <30 had a corrected VT of 9.34 ± 4.63 mL / Kg, not statistically significant, but mportante from a clinical point of view. CONCLUSION: It was found that PTNB below 30 weeks were exposed to VT greater than the ideal range for weight. With this, it is possible to identify the importance of continuous monitoring of the VT, favoring a better ventilatory assistance, minimizing lung injuries.

Authors: Fernández Moreno Aleida
Published: July 2023

Se presenta un sencillo caso hipotético sobre la presencia y la puntualidad de profesionales en los servicios de salud y, derivadas de este, algunas consideraciones sobre la ética en Terapia Ocupacional. La autora invita a pensar en el tema y a realizar una revisión ética desde tres aristas: la ley profesional vigente, los principios de la bioética y la deliberación ética. En las dos primeras no se logra resolver el caso, la salida será planteada desde la deliberación ética. La Terapia Ocupacional colombiana necesita la renovación de su ley profesional, empezar la formación en ética desde los primeros semestres y generar espacios interdisciplinares de discusión, especialmente a nivel de las prácticas profesionales.

Published: July 2023

The nutraceutical efficacy of phytochemical curcumin has been utilized in many therapeutic foods and drugs, thanks to their anti-inflammatory, antimicrobial, antioxidant, antitumor and anticancer activities. Therefore, it is necessary to develop green and scalable methods of isolating the natural products from the Curcuma longa plant. This study presents an environmentally friendly method of aqueous extraction to obtain fine curcumin powder with high purity (84.6 % quantified by HPLC). The fine curcumin combines with montmorillonite clay to synthesize an improved drug delivery vehicle. Synthetically, equilibrium adsorption of curcumin on montmorillonite results in a curcumin-loaded montmorillonite structure. The montmorillonite/ curcumin drug delivery vehicle shows good properties of aqueous dispersibility and curcumin stabilization in the environment of neutral water and natural/ ultraviolet lights. The innovative formulation of montmorillonite/curcumin helps to upgrade the bioavailability and stability of bioactive curcumin in nutraceutical delivery applications.
