CONTEXT BASED ANALYSIS IN THE TRANSFORMATION OF RENDRA'S POETRY MUSICALIZATION
Authors: Fikri Muhammad , Arianto Tomi , Wellem Karmila Alam Syah , Khairunnisa Khairunnisa
Published: June 2023

Poetry holds a very deep meaning that cannot even be only touched by a heuristic approach reading. When poetry is transformed into strings of tones or musicalization, the power of meaning in words will be even more stunning and make the affirmation of words stronger and more rooted. This article will reveal two of Rendra's transformation poems in the form of musicalized poems entitled “Serenada Kelabu” and “Kangen”. This article revealed the negation of "I" in poetry by using theoretical concepts textually and contextually. Textual analysis reveals the use of figurative language through the transformation of the poetry in the third song of Rendra's poem, while contextual analysis seeks to reveal the discourse built through the three poems. The method used in this research is a qualitative research method. The results of this study indicate that Both " Serenada Kelabu" and "Kangen" are poems in which the "I" that is opposed to the "You" and is defined by "love" is used to refer to the speaker. I feel so tormented as a result of my love for myself, tormented by my feelings of loss as well as loneliness. Because of love, "I" ceases to exist independently and is subjected to "you," whose existence only lives in the "I" as shadow.

Tolerance is an important concept when society experiences disputes or conflicts of interest. Misuse of the word tolerance occurs when the word only means there is no conflict on the surface layer of people”s lives. In fact, the potential for conflict is like burning husks. Sowing the seeds of tolerance is not just aimed at eliminating differences or eliminating conflicts. Tolerance is the essence of the existence of society itself. This article will analyze the concept of tolerance and how to raise awareness that tolerance stems from a person”s self-concept in looking at those around him. The following article reviews the ideas behind the term tolerance. Tolerance has breadth and depth of meaning. This study employed qualitative method with literature research design. Data were analyzed with content analysis method. The study results show that tolerance grows as part of the human personality. When humans are able to embrace tolerance, there is a guarantee that the preservation of all differences and all kinds of conflicts can continue constructively. Both must exist for the sake of humanity. It is hoped that the meaning of the value of tolerance will not be manipulated by people who have evil intentions to justify their evil behavior and actions. Nor should the idea of tolerance be used by humble and simple people to hand over their rights to arrogant and greedy people. Tolerance should not benefit the evil one and harm those who live simply.

Published: June 2023

The efficiency of government bureaucracy has long been a topic of debate, with the aspiration of establishing a transparent and authoritative government yet to be realized. State Civil Servants (ASN) are frequently found to be unproductive, neglecting their duties and responsibilities, and lacking in innovation and responsiveness, all of which have hindered progress and advancement. As a response to this issue, the government introduced regulation of the Minister for the Utilization of State Apparatus and Bureaucratic Reform Number 28 of 2019, aimed at simplifying and streamlining the bureaucracy by standardizing administrative positions into functional positions. This regulation was further refined by Regulation of the Minister for the Utilization of State Apparatus and Bureaucratic Reform Number 17 of 2021. However, the implementation of these regulations has been challenging, with numerous issues arising. In order to bring about the desired changes, ongoing studies, analyses, socialization, and the strengthening of apparatus that have undergone standardization are essential. To investigate the problems associated with the implementation of these regulations, this study employs a library research method, utilizing regulations as the primary reference. The findings suggest that the implementation of Regulation of the Minister for the Utilization of State Apparatus and Bureaucratic Reform Number 17 of 2021 has presented significant challenges for both the organization and the functional and structural officials involved.

Authors: Cahyani Novi Ratna
Published: June 2023

The utilization of nickel ore has increased along with the growing trend of electric vehicles. As a country with abundant nickel ore resources, Indonesia has received economic benefits from nickel ore export activities. However, since January 1, 2020, Indonesia has taken a policy to stop the export of nickel ore. Indonesia’s decision is interesting to study for two reasons. First, a ban on nickel ore exports has reduced state revenues. Second, the policy of stopping nickel ore exports creates a bad perception from partner countries that have depended on the supply of raw materials. This research aims to examine why Indonesia implemented the policy of stopping nickel ore exports in 2020. This research explores existing problems using a neomercantilism perspective through qualitative research methods with secondary data sources. The results show that stopping the export of nickel ore is Indonesia's neomercantilist policy to secure the supply of nickel ore and support domestic companies BUMN, to increase their relative position in international trade. It was concluded that stopping nickel ore exports in 2020 had improved Indonesia's relative position in international trade.

UN Convention to Combat Desertification as an International Environmental Regulatory Framework for Protecting and Restoring the World’s Land towards a Safer, More Just and Sustainable Future
Authors: Bristol-Alagbariya Edward T.
Published: June 2023

There are ongoing international initiatives on how to protect the environment towards sustainable development (SD). These initiatives range from those of the United Nations (UN) to those of other international organizations and institutions. At the level of the UN, these initiatives are mainly its conferences and summits, which may be considered as the UN SRJRS Process. The UN SRJRS Process refers to the cities in which various UN conferences and summits on the environment and development towards SD have so far been convened, namely Stockholm, Rio de Janeiro, Johannesburg, Rio de Janeiro and Stockholm. So, these UN conferences and summits are the (i) UN Conference on the Human Environment, held at Stockholm, in 1972; (ii) UN Conference on Environment and Development, held at Rio de Janeiro, in 1992; (iii) World Summit on SD, held at Johannesburg, in 2002; (iv) UN Conference on SD (Rio+20), held again at Rio de Janeiro, in 2012; and (v) the Stockholm+50, which was held again in Stockholm, Sweden, in June 2022. The UN SRJRS Process and their outcome documents and progressively ongoing strategies are aimed at protecting the environment in the course of development, so as to achieve SD in UN’s member states and territories around the globe, in the interest of humans and society at large. Desertification, which may arise from deforestation, is an environmental problem associated with forests. Internationally, forests are regulated by the UN Statement of Forest Principles, 1992, UN Framework Convention on Climate Change, 1992, the Convention on Biological Diversity, 1992, the Convention to Combat Desertification (CCD), 1994, and other relevant multilateral conventions, as well as international agreements and efforts associated with forests. This study thus examines the UNCCD, 1994, as a worldwide shared vision and a comprehensive multilateral environmental regulatory mechanism, designed to combat desertification, through relevant implementation measures, such as policies, laws, institutional regulatory frameworks and practices in sovereign states and territories around the globe, so as to protect and restore the world’s land, towards a safer, more just and better sustainable future, especially towards achieving relevant goals of the UN Sustainable Development Goals.
Assessment of Acoustic Properties of Lecture Theatres in Ladoke Akintola University of Technology, Ogbomoso, Nigeria

Published: June 2023

Acoustic design is an important consideration in the design of lecture theaters (LTs); it has a significant impact on communication between students and instructors, their hearing comfort levels, lecture outputs and their overall performance. However, despite the significant role acoustic design plays in LTs, it has not received a significant attention both in design and literature in the developing countries especially Nigeria. This study is hence aimed at assessing the acoustic properties of lecture theaters in Ladoke Akintola University of Technology (LAUTECH) Ogbomoso with a view to establishing the design requirements for effective acoustic comfort in lecture theatres in Nigeria. Seven (58.33%) lecture theaters were randomly selected out of a total of 12 available in the study area and were objectively analysed. Shape of the lecture theaters, wall, floor, ceiling and furniture surface finishes were physically observed and their sound absorbing coefficients were evaluated and compared with data obtained from the Bureau of standards for the sound absorption coefficients, ISO 354 and literature. The total surface absorption coefficients of materials and surface area were used to calculate the Reverberation Time (RT) using Wallace Sabine model and results was compared with RT standard of between 0.5 and 1.0s recommended by scholars Odoh and Urenyang for LTs in Nigeria. The study observed that walls, floor and ceiling surfaces were treated with materials of low sound absorbing coefficients while only the ceilings were treated with high coefficient materials, the effect was observed in the RT values obtained. It was observed that only 3 (42.86%) LTs have their RTs within the recommended standards and hence are capable of providing good acoustic comfort for users while 4 (57.14%) LTs have excessive RT implying likely acoustic discomfort. The study recommended that materials with high sound absorbing coefficients be used for building component finishes and acoustic decisions should be taken right from design inception stage.

Authors: Mohammed Djaouti Soumia , Khelfi Mohamed Fayçal , Malki Mimoun , Mohammed Salem
Published: June 2023

Tuning a nonlinear inverted pendulum is a complex and uncertain optimization problem. In this paper, we develop two new GWO variants by introducing a DLH (Dimension Learning-based Hunting) module and new formulas to enhance the exploitation/exploration ratio aiming to avoid local minima. A statistical analysis is carried out to compare the two proposed approaches with five GWO variants. After that, they are used to tune a PID and FSMC controller. The obtained results are promising even when compared to other approaches

This paper discusses two-dimensional heat flow of an incompressible non-Newtonian hydromagnetic fluid over a power-law stretching curved sheet. The energy equation of the flow problem considers a radiative flux influenced by viscous dissipation and surface frictional heating. Lorentz force and Joule heating are taken in the consequence of applied variable magnetic field satisfying solenoidal nature of magnetism. The governing equations are reduced to boundary-layer regime using dimensionless quantities and the resulting PDEs are converted into ODEs by suitable similarity variables. The flow fields; velocity and temperature are computed numerically by implementing Keller-Box shooting method with Jacobi iterative technique. Error analysis is calculated to ensure solutions' convergence. Interesting flow parameters are examined and plotted graphically. Results show that velocity is increased for large number of fluid rheology and opposite effects are recorded for increasing curvature, Lorentz force, and stretching power. Flow past a flat and curved surfaces are substantial in validation of this present work.
Model Fitness and Predictive Accuracy in Linear Mixed-Effects Models with Latent Clusters
Authors: Bello Yusuf , Yahya Waheed B. , AbdulRaheem Abdulrazaq
Published: June 2023

In clustered data, observations within a cluster show similarity between themselves because they share common features different from observations in the other clusters. In a given population, different clustering may surface because correlation may occur across more than one dimension. The existing multilevel analysis techniques of the primal linear mixed-effect models are limited to natural clusters which are often not realistic to capture in real-life situations. Therefore, this paper proposes dual linear mixed models (DLMMs) for modeling unobserved latent clusters when such are present in data sets to yield appreciable gains in model fitness and predictive accuracy. The methodology explored the development and analysis of the dual linear mixed models (DLMMs) based on the derived latent clusters from the natural clusters using multivariate cluster analysis. A published data set on political analysis was used to demonstrate the efficiency of the proposed models. The proposed DLMMs have yielded minimum values of the models' assessment criteria (Akaike information criterion, Bayesian information criterion, and root mean squared error), and hence, outperformed the classical PLMMs in terms of model fitness and predictive accuracy.

Published: June 2023

Introduction: The onabotulinumtoxinA (onabotA) is an injectable preventive treatment of chronic migraine (CM), administered in 12 week’s intervals. Some patients present a wearing-off (WO) effect in the last weeks before the next treatment. The aim of our study was to evaluate the WO phenomen in patients under onabotA treatment and to recognize possible predictive features of the phenomena.

Methods: We designed a cross-sectional study and proceeded to demographic and clinical characterization of a group of patients, and evaluation of onabotA therapeutic response and adverse events. WO effect was defined as the loss of therapeutic effect, that consists of reduction equal or greater than 50% in the number of headache days, before the 12-week interval. Statistical testing was carried out using a level of significance of p<0.05.

Results: We included 60 patients (95.1% female) with a mean age of 49.0±11.4 years. On average, before onaBotA treatment patients had around 15.0 attacks per month. In 45.3% we noticed a therapeutic response after the first treatment. The WO effect was noticed in 36 patients (66.7%) and the majority (50.9%) between the 10th to 12th week post treatment. Wearing-off was more reported by patients under 155 units PREEMPT protocol (p=0.032).

Conclusion: This study documents the high frequency of WO phenomen in patients with chronic migraine under onabotA. Therefore, the possibility of a different protocol in selected patients must be explore with larger observational and prospective studies as well as evaluation in clinical trials.
Efeitos do Fortalecimento do Membro Superior, no Equilíbrio e na Marcha, em Idosos Pós-Acidente Vascular Cerebral: Revisão Sistemática
Authors: Figueiredo Vânia , Carvalho Andreia , Mota Patrícia
Published: June 2023

Introdução: A ocorrência de acidente vascular cerebral (AVC) tem uma prevalência elevada na população mais velha, sendo que 30% a 60% destes indivíduos apresentam limitações ao nível do membro superior (MS). A diminuição da amplitude e alteração dos membros superiores podem potenciar alterações ao nível do padrão de marcha, risco de queda e equilíbrio. Estudos referem que fortalecimento dos MS pode melhorar o padrão de marcha e a capacidade funcional em utentes com sequelas de AVC.
O nosso objetivo foi determinar o efeito do fortalecimento do MS, na marcha, quedas e equilíbrio em pé, em adultos com 65 ou mais anos, com diagnóstico de AVC.

Métodos: Pesquisaram-se publicações nas bases de dados PubMed, Cochrane Library e ScienceDirect, com inclusão de ensaios clínicos randomizados, sem limitação de data, que avaliavam o efeito do fortalecimento do MS, na marcha, quedas e equilíbrio, em pessoas com 65 anos ou mais, pós-AVC. Dois revisores, de forma cega, seleccionaram os artigos para inclusão, havendo em caso de discordância um terceiro revisor. Excluíram-se protocolos, apresentações e artigos com pontuação inferior a 5 na escala PEDro.

Resultados: Foram incluídos 6 estudos, com um total de 468 participantes. O fortalecimento do MS interfere positivamente na capacidade de marcha, nomeadamente ao nível da velocidade, é eficaz na prevenção de quedas, promove melhorias no equilíbrio comparativamente ao início da intervenção.

Conclusão: A inclusão do fortalecimento do MS interfere positivamente na melhoria da velocidade de marcha e equilíbrio, podendo condicionar a diminuição do risco de queda nesta população.
Comparison of pharmacy student, evaluator, and standardised patient assessment of Objective Structured Clinical Examination (OSCE) performance
Authors: Barrickman Ashleigh L , Marina Galvez-Peralta  , Lena Maynor
Published: June 2023

Objective: The study aimed to (1) determine if standardised patient (SP) assessment of student communication differs from faculty assessment and (2) identify factors that may affect their assessment scoring since differences between evaluator scoring could impact students’ learning and feedback.
Methods: Students completed four OSCEs in spring 2022. Communication skills were scored using a global assessment rubric completed by a faculty evaluator, SP, and student. SPs and students rated their confidence in student recommendations on a scale of 1-5 (1=lowest; 5=highest). Spearman correlation and Wilcoxon matched-pairs signed rank tests were used for analysis.
Results: SP global assessment scores were statistically significantly higher than faculty scores. SP global assessment and confidence scores were strongly correlated.
Conclusion: Differences in OSCE scoring among evaluator types and factors that may impact scoring are important to explore. SP scores were consistently higher than faculty scores, which should be considered when using OSCEs as assessments.

Islamic bank is a banking system that runs a system of financial activities based on Islamic law. The performance of Islamic banks can be measured by the size of the NPF. Factors that affect NPF basically come from outside and inside the company such as CAR, BOPO, and FDR. This study aims to examine the effect of Non Performing Financing (NPF) from Islamic banks with the Capital Adequacy Ratio (CAR), Operating Costs and Operating Income (BOPO) and Financing to Deposit Ratio (FDR). This research is a quantitative research. The data used is quarterly data at BRI Syariah Bank. In this study using multiple regression data analysis. The classical assumption tests used in this research are normality, multicollinearity, heteroscedasticity and autocorrelation. The research shows that NPF has a positive and significant effect on CAR, BOPO, and FDR. The predictive capability of the three variables on the NPF is 56.6%, while the rest are affected by other factors outside the research model
Pengambilan Keputusan Pemberian Kredit Berdasarkan Karakteristik Nasabah dan Informasi Akutansi Pada PT. Bank Rakyat Indonesia (Persero) Cabang Rantauprapat

Credit facilities provided by banks are the biggest assets for banks. Based on the author's observations at PT. Bank Rakyat Indonesia (Persero) Rantauprapat Branch at the time of pre-research it was known that the decline in credit realization was due to the low quality of accounting information held by customers. It can be seen that there are still many customers who do not have a good report on the company's health condition. So that in making the decision to grant credit at PT. Bank Rakyat Indonesia (Persero) Rantauprapat Branch is still based on trust and some use guarantees from large debtors or debtors who have been trusted by the bank. So that many prospective debtors based on the results of the assessment are not good, but because there is a guarantee from a third party, the credit application can still be realized. This results in a weak assessment of credit applications in looking at the characteristics and accounting information possessed by prospective debtors in making credit decisions, because some debtors do not need to go through credit analysis selection and financial statement assessment. Weak assessment causes weak credit decision making. Therefore we need a way of making decisions in granting credit. With the aim of making it easier for the bank to make credit decisions to colon customers. Based on the hypothesis testing is done by testing the partial significance test (t-test) and significant test. Simultaneously (f-test) where the calculation that the current ratio has a tcount value of 2.122 is greater than t-table 1.989 (tcount> ttable: 2.122>1.989) thus Ha is accepted while H0 is rejected. So it can be stated that the current ratio variable has a significant effect on = 0.05 on the decision to grant credit to the decision to grant credit. And the F value of 34,872, thus simultaneously the current ratio, return on equity, credit guarantee and debtor motivation variables have an Fcount of 34,872 which is greater than Ftable 2.483 (Fcount> Ftable: 35,383> 3,259). Thus, the effect of the independent variables (current ratio, return on equity, credit guarantees and debtor motivation) is simultaneously positive and significant on the dependent variable (credit granting decisions) at PT. Bank Rakyat Indonesia (Persero) Rantauprapat Branch.
