Third Space of Communication in Soekarno's Thought
Authors: Saintio Fidelis Aggiornamento , Sujoko Anang , Sobari Wawan
Published: April 2021

Viewed from the perspective of the third space of communication, colonialism is no longer a moment of the West’s domination over the East. The boundary between superiority and inferiority is removed by exchanges of influences. In addition, the third space of communication can also be used as a means of fusing different cultures and values. However, when applied in certain contexts, there are opportunities to enrich the idea of a third space of communication. The enrichment of this idea can be found in the state speech made by President Soekarno on June 1, 1945. Apart from formulating the foundation of the Indonesian state, the speech also aimed to unite the diverse Indonesian peoples into one national identity. Through a hermeneutics analysis, it was found that there was no need to fuse or remove diversity to form a third space of communication

Bioactive compounds are the group of secondary metabolites of plants that have a potent impact on antimicrobial and antibiofilm agents. Although Curcuma longa (turmeric) is well known for its antimicrobial activity, the question arises if curcumin, the primary bioactive compound is only responsible for it or the synergistic and simultaneous contribution of more than one bioactive compound are responsible for this antibiofilm efficacy. The research work aims to determine the efficacy of the extract Curcuma longa has a higher potential of antimicrobial and antibiofilm activity than the purchased curcumin and standard antibiotic. Present work was initiated with GC-MS analysis of the ethanolic extract of Curcuma longa (turmeric) and showed that in addition to curcumin, methyl palmitate de-hydro zingerone had a higher percent of availability within the extract. The in-silico studies also showed that when targeted upon Gram-positive biofilm-forming protein of Staphylococcus aureus (3TIP), curcumin alone had a binding constant value of -6.33 Kcal/mol but showed a value of -17.811 Kcal/mol when acted in association with Dehydrozingerone. Similarly, the binding constant's value changed from -6.07 Kcal/mol to - 23.844 Kcal/mol, when Gram-negative biofilm-forming protein (3ZYB) of Pseudomonas aeruginosa was acted upon by curcumin only and in association with methyl palmitate, respectively. Lower minimum inhibitory concentration (MIC) and higher effectivity in reducing the bacterial quorum sensing (QS) activity of the turmeric extract than pure Curcumin indicated the higher antimicrobial and antibiofilm efficiency of the extract, respectively. This indicated clearly that the synergistic action of all the bioactive compounds imparts the antibiofilm activity of turmeric. The result was further confirmed by the scanning electron microscopic (SEM) studies, fluorescent microscopic studies, and FTIR analysis of EPS as well.

Authors:   Dept. of Statistics, Federal University of Technology, P.M.B 704, Akure, Nigeria, Makinde Olusola S.
Published: April 2021

Several multivariate depth functions have been proposed in the literature, of which some satisfy all the conditions for statistical depth functions while some do not. Spatial depth is known to be invariant to spherical and shift transformations. In this paper, the possibility of using different versions of spatial depth in classification is considered. The covariance-adjusted, weighted, and kernel-based versions of spatial depth functions are presented to classify multivariate outcomes. We extend the maximal depth classification notions for the covariance-adjusted, weighted, and kernel-based spatial depth versions. The classifiers' performance is considered and compared with some existing classification methods using simulated and real datasets.

Schizophrenia is a psychological disorder, way tougher to diagnose than other psychological disorders, as it shares similar symptoms with psychosis. As we know, schizophrenia occurs due to chemical imbalance in the brain; identifying the role of neurotransmitters in schizophrenia poses a vital area to study. Neurotransmitters being the sole carrier of different brain activities, researchers have already initiated studies to investigate their role and effect in disorder. Firstly, this paper performs a critical review of the literature that dealt with different neurotransmitters in schizophrenia. Secondly, we identify the most important neurotransmitters and broadly elaborate on their functional roles and effects on the disorder. Finally, we have successfully identified various gaps and unexplored research questions to investigate these neurochemicals' role. Studies show that neurotransmitters like dopamine, glutamate, GABA, serotonin, and oxytocin are majorly responsible for schizophrenia, among which dopamine contributes the most. To the best of our knowledge, this paper encapsulates all the neurotransmitters, enzymes, and chemicals for the first time and explores their related literature. This study also identifies the most responsible chemicals involved in schizophrenia and unfolds the research community's unsolved problem.

Water demand in the world increases rapidly every year, especially in urban areas due to population growth and improved economic conditions. The largest freshwater source on earth is groundwater that can be utilized and easily obtained. However, the number of groundwater resources is very dynamic, depending on the recharge and discharge, including groundwater extraction. Increasing groundwater abstraction will cause a decline in groundwater level and seawater intrusion in the coastal area. Groundwater level fluctuation trends can be used to estimate groundwater recharge for optimum utilization. Therefore, this study aims to find the trend of groundwater level fluctuation related to rainfall to estimate the groundwater recharge in Yogyakarta City, Indonesia. The study was carried out by measuring the groundwater level of four monitoring wells that spread evenly in Yogyakarta City from 2011 to 2017 every month and comparing the result to monthly rainfall and annual groundwater abstraction from hotels in Yogyakarta City. The annual trend of rainfall and groundwater level fluctuation analysis using the nonparametric Mann-Kendall test and analyzing the trend's magnitude using the nonparametric Sen’s method. The groundwater recharge was estimated by using the water table fluctuation (WTF) method. The study results showed that the trend of rainfall and groundwater level fluctuation is positive in the city's western and eastern parts. However, the groundwater level fluctuation in the city's central and southern parts is a negative trend due to groundwater over-exploitation by hotels. Groundwater recharge is estimated at around 158 up to 538 mm/year based on the WTF method. Higher groundwater recharge was identified in the city's central and eastern parts due to the high contribution from urban wastewater recharge.

Regular consumption of dietary fibre (DF) has been proven to reduce the risk of non-communicable diseases, which leads to the rising demand for DF-enriched products. The study aims to investigate the effect of Pleurotus sajorcaju powder (PSP) incorporation on the nutrient composition, sensorial acceptability, and glycaemic index (GI) of the developed tortilla. Four tortilla formulations with different PSP levels (0%, 5%, 10%, and 15%) to replace wheat flour partially were prepared. The control tortilla's protein concentration was 8.26% and increased to 9.31, 9.72, and 10.60% when incorporated with 5, 10, and 15% PSP, respectively. Both the 10% and 15% PSP tortilla (12.00% and 13.62%) were found to be significantly higher than the control tortilla in total DF. The β-glucan content was the highest in the tortilla with 15% PSP added (1.21%). In sensory evaluation, the tortilla fortified up to 15% PSP was apparently well accepted by the sensory panelists. Control tortilla had an intermediate GI value (58) while 15% PSP tortilla had a low GI value (53). In summary, adding up to 15% PSP in the tortilla formulation increased nutritional values, improved sensorial attributes, and reduced GI value.

Authors: Midha Nidhi , Yadav Sachita , Srivastava Sanjay
Published: April 2021

Purpose-Social Media has become an integral part of today's life. The business world has seen numerous opportunities in its application, and it has added new dimensions to the marketing function. This paper studies the impact of social media marketing (SMM)
functionalities on the brand equity elements for the white goods brands in India.
Design/Methodology/ Approach-The study approaches social media functionalities and
brand equity as developed by the ISMBE model (Babac,2011) and explores the impact of
social media marketing (SMM) variables on the brand equity of the white goods brands in India. The researcher has drawn from past studies on social media marketing and study of brand equity to develop a standardized questionnaire which was administered on a random sample of 150 respondents using Google forms. Various tests of reliability and validity were applied to test the variables, data was analyzed using linear and multiple regression, and finally regressions equations were established to understand the impact of dependent and independent variables.
Findings-The study is effective in determining that social media marketing is helpful in
building brand equity. The study stresses that white goods brands should consider social media marketing to access consumers in a cost-effective way to build and strengthen brand equity. The findings of the research corroborate with the framework suggested in the ISMBE model.
Originality / Value-There is very little research done in the areas of social media marketing and its impact on consumer-based brand equity. While past research has dealt with some categories of brands like mobiles, fashion, malls etc. but there is no study on impact of social media variables on the brand equity of white goods brands in India therefore to that extent it contributes to a fresh understanding on this category in India.
Marketing in the New Era: Investigating the Personality Antecedents of Materialism, Consumer Insecurity, and Consumer Loneliness
Authors: Kansal Purva , Singh Neha
Published: April 2021

Purpose-By investigating the impact of personality antecedents on marketing influenced
surface traits (i.e., Materialism, Consumer Loneliness and Consumer Insecurity), the current research tries to take a step forward in understanding the real impact marketing activities have, on these surface traits.
Design/Methodology/Approach: Following a descriptive research methodology, data for
the current study were collected from 174 respondents using standardized scales and
hypotheses were tested using CFA and SEM analysis (AMOS (v23)).
Findings: Results confirm the existence of a significant relationship between surface traits and personality traits, substantiating the theory that certain personality traits are inherent to the risk of being associated with these surface traits, and therefore the real impact of marketing activities might be much lower.
Originality/Value: With marketing activities being criticized because of its negative impact on the society (which has been proved in the literature immensely), the current paper tries to give the debate a new perspective by studying the other antecedents (personality) of these 'negative consequences', in order to better understand the real affect of marketing activities.
Implications: Marketers can take into consideration the results of the current study and
incorporate them while making advertising decisions so that marketing actions elicit a more positive reaction than negative ones.

Escribir en las universidades a distancia: formación y diﬁcultades de los estudiantes
Authors: Núñez Cortés Juan Antonio , García de la Barrera Trujillo María José
Published: April 2021

Enseñar a escribir en la universidad es un reto al que tienen que hacer frente los responsables de la educación superior: profesores universitarios y gestores académicos. Esto supone un desafío no solo en las universidades presenciales, sino, y por diferentes motivos, en las universidades a distancia. Por esto, conocer la opinión sobre la escritura académica de los estudiantes de estas universidades y sobre la formación que han recibido para aprender a escribir es fundamental para poder tomar decisiones. Este es el objetivo del estudio que se presenta. Para ello, se ha realizado un cuestionario en línea a 160 estudiantes de cinco universidades a distancia españolas. Algunos de los aspectos que se han abordado están relacionados con la importancia otorgada a la expresión «escrita», las diﬁcultades que tienen a la hora de escribir, las funciones de la universidad, la formación en estrategias de composición de textos y en géneros académicos, así como las iniciativas que llevan a cabo los profesores para enseñarles a escribir. Los resultados muestran que pese a la importancia dada por profesores y estudiantes a la escritura, los problemas todavía se tienen que resolver. Asimismo, se muestra cómo en general predomina una formación más teórica que práctica. En consecuencia, se sugiere la puesta en marcha de iniciativas que gozan de una percepción positiva por parte de los estudiantes, como son, en el marco de un centro de escritura en línea, las tutorías de escritura por parte de profesores especialistas y la sistematización de recursos didácticos en un repositorio institucional.
Funcionalización de superﬁcies anti-fouling sobre titanio para mejora de sus propiedades
Authors: Buxadera-Palomero Judit , Mas-Moruno Carlos , Rodríguez Rius Daniel , Manero Planella José María
Published: April 2021

Actualmente las infecciones de implantes y prótesis son un problema grave, debido al incremento de uso de dichas prótesis y a la cada vez mayor presencia de bacterias resistentes a los antibióticos. Estas infecciones tienen su origen, en la mayoría de casos, en bacterias planctónicas. Una posible estrategia para evitar las infecciones es desarrollar superﬁcies anti-fouling que eviten la adhesión bacteriana. Otra estrategia se centra en conferir propiedades bactericidas a las superﬁcies de los implantes en el uso de péptidos antimicrobianos. En ambos casos, es necesario mantener la excelente unión a los tejidos que presenta el titanio.
La superﬁcie ideal para prótesis combinaría los efectos anti-fouling, bactericida y osteointegrativo, logrando un excelente efecto sinérgico en las superﬁcies de los implantes, mejorando su estabilidad y funcionalidad. Para conseguir este objetivo es necesario solventar un punto crítico, que es funcionalizar la capa anti-fouling con otras biomoléculas que permitan dotarla de las propiedades mencionadas.
El objetivo del presente trabajo es depositar una capa anti-fouling sobre un biomaterial metálico con un grupo funcional que permita enlazar a la superﬁcie tratada otras biomoléculas. Se ha conseguido depositar una capa de (poli)etilenglicol (PEG) funcionalizado sobre titanio, al cual se ha unido la secuencia tripeptídica Arg-Gly-Asp (RGD). Las superﬁcies tratadas han mostrado una excelente combinación de propiedades anti-fouling y de buena respuesta celular.

A vaccine for the virus called corona or what is known as covid 19 has not been found, which has eaten a lot of people, from those who were only infected to those who breathed their last. The plague like this makes all countries in the world forced to take preferential steps to prevent its spread that is increasingly widespread. One of the steps taken by the Indonesian government is social distancing. Such restrictions in turn also affect the education sector, in which all schools and campuses are closed. Of course, educational activists will not let the teaching and learning process take off. Online schools are one of the solutions taken by many educational units in Indonesia. Besides online schools, the ruangguru tutoring platform which provides a lot of material is also used as a place to study. This study will further analyze the role of the ruangguru in developing children's creativity in this pandemic era. The research model is a sentiment analysis. The results showed that positive comments about ruangguru reached 430, negative comments reached 57, and mediocre comments reached 14.

If seen in astate of infra-structure that covers the center of the political power of thepeople, contained in elements of social organization, political figures,community leaders, the tools of political communication, and especially apolitical organization or political party is able to affect the workings of theapparatus of the public to express, distribute, translate, convert demands,support and the specific problems associated with the public interest, especiallyin this case the education sector, the government has given freedom inexpressing their opinions. It is proved that the Indonesian State has beenattempted in the give attention to education for its citizens. Because with aquality education will be able to improve economic growth and development ina Country. However, the education budget by 20% is considered not able tomaximize the improvement of the quality of education in Indonesia, so the needfor a new policy in increasing the percentage of the budget for education.

Relationship Between Academic Stress and Learning Achievement in Nursing Student
Authors: Panma Yuanita
Published: April 2021

The stress experienced by most students is academic stress. This academic stress is closely related to students' academic processes and the environment that affects the academic process. The purpose of this study was to determine the relationship between academic stress and student learning achievement. This study was a cross-sectional design with purposive sampling of 126 respondents. Data were collected at a nursing academy in Jakarta in 2018. The instrument used was the Student Life Stress Inventory (SLSI) questionnaire. Results showed most students were female(88.9%), from Senior High School majoring in science (38.9%), very satisfyinglearning achievement (91.3%), and experience severe academic stress (55.6%). There is no significant relationship between learning achievement and academic stress (p = 0.317) and gender (p-value 0.370). There is a significant relationship between learning achievement and sebior high school majoring (p=value 0.005) and age (p-value 0.007). Institutions should identify sources of the academic stressor and apply appropriate coping mechanisms to reduce academic stress.Keywords:academic stress, learning achievement, nursing student.
Ijtihad From Friends Of The Prophet Muhammad In Making Justice Law
Authors: Hidayat Nur , Jafar Wahyu Abdul
Published: April 2021

This study explains that ijtihad existed when the companions of the Prophet Muhammad were still alive and continued to develop along with the development of Islam. Ijtihad was born because it is a logical reflection of the struggles of various situations in society that require solutions to be found. However, it should be noted that not everyone can perform ijtihad because ijtihad must use the science of ushul fiqh. Ijtihad, which is carried out carelessly can produce a perverted legal product, as is the case today. Therefore, through this study, the author discusses the ijtihad practised by the companions of the Prophet Muhammad before the emergence of the science of ushul fiqh. The purpose of this discussion is to find out whether the licensed products that were born before the emergence of ushul fiqh science are legally flawed or not. After conducting an in-depth study, it was found that even though at that time the science of ushul fiqh had not been recorded in one book, the companions of the Prophet Muhammad were able to formulate and produce Islamic law products precisely. This happens because they master the science of ushul fiqh and keep it well in their memory.
Euthanasia dan Bunuh Diri Ditinjau Dari Hukum Islam Dan Hukum yang Berlaku di Indonesia
Authors: Nugroho Irwan Budi
Published: April 2021

This study aims to determine the causes of people committing euthanasia and suicide, knowing the Islamic legal view of euthanasia and suicide, and knowing the legal views in Indonesia regarding euthanasia and suicide. The literature study method was used in this research. After conducting the discussion, the researchers found: 1) The causes of euthanasia include: insufficient economic factors, drug prices and medical treatment costs that are too expensive and unreachable, diseases convicted of being incurable by the medical team, consideration of hospital rooms, health workers, and hospital equipment deemed usable another patient, a sense of humanity, a consideration of deserving death rather than a life of torment, and a desire to lighten the burden of the sick. 2) Personal egoism, the desire to defend others, the urge to defend certain groups, the burden of life, and burdensome regulations can cause a person to commit suicide. 3) In essence, both Islamic law and Indonesian law prohibit euthanasia and suicide.
Multi-sensor analyses of the skin temperature for the assimilation of satellite radiances in the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS, cycle 47R1)

Abstract. The assimilation of clear-sky radiance in the European Centre for Medium-Range Weather Forecasts (ECMWF) atmospheric analysis relies on the clear-sky radiances observation operator. Some of these radiances have frequencies that make them sensitive to both the surface and atmosphere. Because the atmospheric and surface analyses are currently not strongly coupled, a specific treatment of the surface is required. The observation operator expects in particular, a skin temperature value at the observation location and time, together with the profiles of the atmospheric variables along the viewing path. This skin temperature is added to the control variable and optimised simultaneously with all the atmospheric variables to produce optimal simulated radiances.We present two approaches to add the skin temperature to the control variable. In the current TOVSCV approach, a series of skin temperature value per observation location is added to the control variable. Effectively, in the optimisation process, the skin temperature acts as a sink variable in observation space and is uncoupled from the skin temperature at other locations. In the novel SKTACV approach, two-dimensional skin temperature fields are added to the control variable. All clear-sky radiances then participate in the optimisation of these two-dimensional fields and the analysis produces temporally and spatially consistent skin temperature fields.We compare the two approaches over two seasons of three months each. Overall, there is a neutral impact of the new approach on the analysis and forecast. Besides, there are some evidences that the contribution of the sub-surface layers should be represented in the new approach for the skin temperature associated with the microwave instruments.
