The emergence of antibiotic-resistant strains of microorganisms calls for research and the development of strategies to curb this menace. The screening of antimicrobial compounds from endophytic fungi is a promising way to meet the increasing threat of drug-resistant. This study aims at evaluating the antimicrobial activity of the endophytic fungal extract of Colletotrichum sp. from the leaves of Vernonia amygdalina (Del). Endophytic fungal isolation, cultivation, and identification were carried out using standard methods. Subsequently, fermentation and extraction of the secondary metabolites were done on a rice medium. About 1.2g of the fungal extract was subjected to vacuum liquid chromatography (VLC) using gradient-based elution; n-hexane and ethyl acetate followed by dichloromethane and methanol. The high-performance liquid chromatography (HPLC) analysis of the crude extract and VLC fractions were also carried out. Gel permeation chromatography using Sephadex LH-20 was carried out on Fraction JT2. Antimicrobial Assays for fraction JT4 and the Sephadex LH-20 fractions (JT2C – JT2E) were also carried out. The results were analyzed using Statistical Package for Social Sciences. The high-performance liquid chromatography (HPLC) analysis of the crude extract and VLC fractions revealed the presence of the five bioactive metabolites (acropyrone, beauvericin, indole-3-carbaldehyde, indolyl-3-acetic acid, and rocaglamid A). The result of the antimicrobial activity of the VLC fraction, JT4, showed that the fraction exhibited a significant inhibitory effect against Bacillus subtilis, Pseudomonas aeruginosa at 0.25 – 1 mg/ml (IZD) and antifungal activity against Aspergillus niger only at 0.0625 – 1 mg/ml (IZD). The result of the antimicrobial activity of the gel chromatographic fractions revealed a significant effect against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli at 0.0625 – 1 mg/ml and had no inhibitory effect against Bacillus subtilis, Aspergillus niger and Candida albicans. The results of this study show that endophytic fungi on V. amygdalina could be a potential source of bioactive compounds for the development of potential and effective antibiotics.

Determinant of Intention to Purchase Halal Cosmetics: A Millennial and Z Generation Perspective
Authors: Nurcahyono Nurcahyono , Hanifah Asma'
Published: April 2023

In recent years, the halal industry has become a trend, this is because the Indonesian people have begun to apply halal culture as a lifestyle. This article aims to determine the factors influencing the purchase intention of halal cosmetics among millennials and generation Z. The author uses the theory of planned behavior to identify factors that encourage a person's intention to buy halal cosmetics among millennials and generation Z. The variables or predictors are attitudes, halal awareness, subjective norms, knowledge, halal labels, buying behavior, brand image, psychological risk, social media, and religiosity. This study has advantages compared to others because it uses a psychological approach in the form of buying and risk behavior and uses the effects of social media. The data was obtained through a survey conducted by the millennial generation and generation Z, who live in the city of Semarang. The sampling method used was non-probability with a purposive sampling technique. The data analysis of this research used Structural Equation Modeling (SEM) � Partial Least Square (PLS) with WarpPLS application. Testing is done using the measurement, goodness of fit, and structural models. The results showed that the factors influencing the purchase of halal cosmetics are attitudes, subjective norms, knowledge, halal labels, buying behavior, brand image, psychological risk, and religiosity. However, the halal awareness variable, social media, is not a determinant of someone buying halal cosmetics. The results show that the halal awareness of research respondents is still low because they have not fully paid attention to the halal aspect. Currently, social media provides too much information, making it difficult to distinguish whether it is credible or not, so respondents choose other alternatives.

Published: April 2023

Introduction: As various pterygium morphologies have been advocated as contributing factor on corneal astigmatism, little support in the literature available in establishing techniques in measuring pterygium thickness as clinical indicator.Objective: The aim of this study was to describe a quantitative method in determining pterygium thickness using anterior segment optical coherence tomography (AS-OCT).Methods: Anterior segment imaging was performed using enhanced high resolution cornea (EHRC) of Visante™ AS-OCT in 120 primary pterygium eyes. Prior to imaging, corneal topography assessment was performed on each pterygium eye in order to identify its topographic location. Based on topography mapping, three meridians (in degrees) were selected as close as possible to the pterygium border, which signify the demarcation of pterygium from the cornea. Reliability testing between intra and inter-observer of AS-OCT imaging modality was examined using intraclass correlation and scatter plot.Results: The overall (n = 120) mean and standard deviation of pterygium thickness EHRC of AS-OCT modality were 0.48 ± 0.10 mm (confidence interval: 0.45 – 0.50). EHRC of AS-OCT also showed excellent intra and intergrader reliability in measuring pterygium thickness with intraclass correlation of 0.997 (confidence interval: 0.994 – 0.998).Conclusions: EHRC of AS-OCT imaging modality is a better choice in assessing pterygium compared to traditional slit-lamp biomicroscopy. This tool is applicable for future work related to better understanding on the role thickness in pterygium morphology, its progression and prediction of induced corneal astigmatism and visual impairment due to pterygium.

Low Molecular Weight Antioxidant versus Flavonoids in Combating Oxidative Stress: Which One is Superior?
Authors: Nasihun Taufiqurrachman
Published: April 2023

According to the free radical theory of aging, firstly proposed by Denham Harman, the most prominent cause of aging and degenerative diseases (DD) is continuously chemical reaction in cells and tissues. In this context aging and or DD is manifested as chemical composition, whilst aging process is reflected by chemical reaction affected by environment (Harman, 1981). Thus, both aging and DD have similar process, predisposed with oxidative stress and characterized by the progressive cellular alteration accumulation in line with time and account for increase in susceptibility to diseases and death. The most prevalent chemical reaction is between free radical reactive oxygen species (ROS) and reactive nitrogen species (RNS) with cellular biomolecules such as lipids, protein, carbohydrate, and DNA (Lamichhane et al., 2013). In order to prevent the deleterious effect of that chemical reaction, human’s body provides an antioxidant defense system to counterbalance the free radical dangerous effect. However, owing to inappropriate life style, eating style, physical activity, and poor environment, production of ROS and RNS may be increased and induce cellular damages. Numerous publications indicated that oxidative stress and cellular damages can be reduced even prevented by exogenous antioxidant, thus intake antioxidant from external sources is necessary. There are two type of exogenous antioxidant consisting of low molecular weight antioxidant (LMWA) and flavonoids. Unfortunately, the effect of LMWA on delaying aging and ameliorating DD remain inconsistent. On the other hand, numerous data indicate that flavonoids a botanical antioxidant was capable of improving oxidative stress and emerging as an alternative promising antioxidant (Sudhakaran et al., 2019). However, the effect of LMWA and flavonoids in combating oxidative stress remain unknown which one is better.

Published: April 2023

Background: Recent studies have identified that chronotropic incompetence is correlated with poor cardiometabolic health and systemic inflammation that results in exercise intolerance, impaired quality of life and death due to cardiovascular disease (CVD). Unfortunately, there’s still paucity of data regarding cardiometabolic factors associated with chronotropic incompetence. The purpose of this study was to identify the cardiometabolic factors associated with chronotropic incompetence.

Methods: This study was a cross-sectional retrospective study using cardiac treadmill stress test data at Sanglah General Hospital from May 2018 - May 2020 and 136 patients were enrolled. Data analysis used SPSS version 21. Pearson chi-square test was used to compare categorical variables based on cardiometabolic risk factors in chronotropic incompetence.

Results: Patients were divided based on the characteristics of age, gender, smoking status, body mass index, coronary artery disease, heart failure, hypertension, dyslipidemia, type 2 diabetes mellitus (T2DM), the levels of HbA1C, total cholesterol, LDL, HDL, and triglyceride. In this study, it was found that T2DM (PR 2.29; 95%CI 1.16–3.37), HbA1C (PR 3.13; 95%CI 2.31-4.22), dyslipidemia (PR 1.773; 95%CI 1.170–2.687), high total cholesterol (PR 2.396; 95%CI 1.650-3;481), and high LDL level (PR 1.853, 95%CI 1.229-2.794) were significantly associated with chronotropic incompetence (all p-value <0.05), while other factors were not significantly related.

Conclusion: Chronotropic incompetence can impair quality of life and contribute to cardiovascular mortality. However, T2DM, high HbA1C, dyslipidemia, high total cholesterol and LDL levels were found to be associated with chronotropic incompetence. This may contribute to higher cardiovascular risk attributed to those factors.

Abstract

Background: Heart valve disease is still a significant health burden in the world, including Indonesia. The postoperative outcome of mitral valve surgery is influenced by many things, including decreased right ventricular (RV) function, which is the most common complication. Several studies have shown that decreased RV function after mitral valve surgery is associated with long-term outcomes. TAPSE is a routine and easy measurement of RV systolic function. A decrease in TAPSE after cardiac surgery is common because of the effects of pericardiotomy, and does not necessarily reflect a decrease in RV ejection fraction (RVEF). Regardless of whether postoperative TAPSE values ​​indicate right ventricular systolic function or only due to the effects of pericardiotomy, it is still not clear whether postoperative TAPSE values ​​have a prognostic value to long-term mortality after mitral valve surgery. Therefore, the objective of this study is to obtain information regarding the relationship of TAPSE echocardiographic parameters after mitral valve surgery with long-term mortality.

 

Methods: This is a retrospective cohort study, looking at the effect of TAPSE on outcome after mitral valve surgery. The analysis starts from the starting point of the study when the patient was discharged alive from the hospital after mitral valve surgery (operation period January 2016 – February 2017) to the end point of the study, which was June 30th, 2021 and the observed outcome was mortality from any cause. Results: Of the 266 study subjects, 11 subjects died within 4-5 years after mitral valve surgery, the mortality is 4%. Bivariate analysis was performed on several factors and no relationship was found between the analyzed variables and mortality.

Conclusion: There is no relationship between mortality and TAPSE after mitral valve surgery.

The study was carried out to determine the competencies needed for improving teaching among lecturers of polytechnics in North-western Nigeria. A polytechnic was established in Nigeria to train individuals to learn a specific skill using competent lecturers for employment or self-reliance after graduation.These lecturers are very essential to the quality of students of electrical/ electronic technology in the polytechnics. However, technology dynamism has become a serious challenge for the lecturers to perform their teaching tasks. Hence the need for lecturers to continually improved on their competence and knowledge of the subject matter content they teach.The study is also to identify any difference of competency needed among the institutions. 122 electrical/electronic lecturers from nine universities were purposely selected as respondents for the study whose consisted of 55 lecturers fromfive state polytechnics and 67 lecturers fromfour federal polytechnics. The study adopted survey research design and used structured questionnaire as the main instrument for the data collection. The questionnaires were developed and distributedtorespondents.Mean and improvement needed indexanalysis were used for data analysis to achieve the research objective whilst t-testwas used to test the significance difference between the institutions.It was found that electrical/electronic lecturers in polytechnics need improvement of their competencies related to knowledge and skills in the subject matter. However, there was no significant difference of competency needed between the lecturers in state and federal polytechnics on the teaching subject matter. The implication of the finding is that the location of the lecturers did not significantly affect their opinion in the competencies.In conclusion, lecturers of electrical/electronic technology from the polytechnics has low competency in executing technical task assigned to them within the study area which required adequate investigation by determining the competencies of lecturers who happen to be the main implementers of the electrical/electronic programme. Therefore, it isrecommended that the schools administrators should continually organized workshop and training for lecturers to build their capacity in order for the lecturers to always develop their competencies to effectively teach the contents of the subject assigned to them.

Cooperative learning is a student-centered learning technique that can be considered a learning strategy for improving student performance both intellectually and in soft skill acquisition. Changesin curriculum structure in vocational institutions, because of the TVET transformation in 2012, have had an unforeseen influence on teaching and learning, whereas in the prior framework, a detailed teaching guideline was supplied compared to the latest structure. Teachers with inadequate knowledge and experience in learning strategies struggled to execute the new curriculum structure due to the lack of depth in these recent curriculum structure. This may be seen in the case of construction drawing subjects, where there were originally 14 main topics but now there are just four. Thus, the goal of this research is to help these teachers by offering a guideline for creating lesson plans that use a cooperative learning strategy. The aim of this paper is to identify and highlight the important component in the creation of a lesson plan using cooperative learning. For this investigation, the fuzzy Delphi technique was used. The main instrument for this study is a questionnaire survey that was developed utilizing a construct identified through literature and the results of a previous needs analysis. A total of 15 expert panels were chosen as the sample, which included university lecturers, vocational college instructors, officers from the Ministry of Education's Technical and Vocational Training Division, and industry representatives. The data was analyzed with the help of Microsoft Excel FDM. Visual skills, Cooperative Student Team Achievement Division (STAD), Power Point, and demonstrations components have been recognized as the major component to include in the lesson plan based on the analysis. With these components identified, a good lesson plan guideline for the next phase of this study can be constructed. It is envisaged that the development of such guidelines would help to elevate the practice of teaching and learning to the next level.

This study employs an experimental designwith pre-and post-test control groups to class-XI vocational students. We taught vocational students about brake pad fabrication and its industrial applications.Conventional methods of instruction were used in the control class, while the experimental demonstration method with learning videos was used in the experimental class.The learning videos used in the experimental class during the learning process contain basic theory and experiments on related materials. The resultsof the pre-test and post-testscores were analysed and measured to determine student learning outcomes. The findings revealed differences in learning outcomes between the control and experimental groups. Students in the experimental groupcomprehended the concept of fabricatingbrake pads more thoroughly than students in the control group. Students can get concrete examples from the teacher or instruction through experimental demonstration. Practical experience can help to form strong memories and skills. This success can be attributedto the availability of learning videos that students can watch repeatedly. Students are also more enthusiastic about learning videos because we teach something that can be applied in the industry. The addition of experimental demonstrations using commercially available materials increases student interest by increasing students' ability to experiment on their own.In addition, we also explain the concept of recycle and reuse agricultural waste for fabricating brakepad that can support current sustainable development goals (SDGs).Further learning applications using experimental demonstration methods are expected to be carried out because this method is proven to be effective for student learning

The purpose of this study is to introduce sustainability literacy to vocational students through distance learning with experimental demonstration as well asshow the production process of ionic liquid and its application as a fire-retardant agent. The method was the implementation of distance learning with an experimental demonstration method to 40 vocational students through three stages, namely given a pre-test; given an instructional video, and given a post-test. The learningprocess carried out was assisted by a learning video containing basic theory, experiments, and the application of ionic liquids. In this case, we taughtthe concept of manufacturing ionic liquid and its application in the industrial world that will be useful for vocational students when they graduate. The results showedthat the experimental demonstration method succeeded in improving student learning outcomes because of an increase in the score between the pre-test and post-test scores. This success is because students are taught through unique learning media such asa learning video. This learning videosucceeded in increasing students' understanding because the information in the video was presented attractively to stimulate students' curiosity and interest in the subject. In addition, students' responses to the learning video werethat they became moreenthusiastic aboutlearning because the content delivered relatesto the vocational training that they are learning, the video display is attractive, and the videos are easily accessible. Furthermore, the impact of the learning video on industrial applications is that the information conveyed in the video can be an alternative to making environmentally friendly solvents and solutions to improve the quality of bamboo as one of the materials used in industry. The addition of an experimental demonstration using commercially available materials also attracts students more because it motivates them to try it themselves. This study shows that experimental demonstration is effectively used in learning and fosters sustainability values in students.

Vocational education and training plays a crucial part in the creation of decent job. The fast growth of information and communication technology (ICT) during the past ten years has increased work opportunities for laborers. This research uses the yearly labor force survey data to study the impact of vocational education and training on decent job opportunities for employees in the context of Vietnam's information and communication technology development. The logit model results indicate that the 2020 rate of decent jobs is still low, at approximately 25.6 percent. However, vocational education and training and the advancement of ICT positively affect decent job opportunities. This long-lasting impact affects laborers in various areas, regions, and industries. These findings suggest that vocational education and training and ICT must play a significant role in transitioning from precarious to more secure employment, so laborers must acquire professional knowledge and information technology skills.

Psychological resilience is the ability to manage psychologically or emotionally with a catastrophe or to swiftly recover to pre-crisis position. Adversity is one of the most important abilities for psychological resilience. Workers in the twenty-first century must be able to deal with adversity in a challenging work environment, especially during a pandemic.The purpose of this study was to determine the level of adversity quotient among Malaysian employees during the pandemic period. Different employees' ability adversity quotients have also been compared in terms of gender, race, and age. This study's design is a cross-sectional surveywith 585 respondents from all around Malaysia selected using a convenient sampling technique. A modified version of Dr. Paul G. Stoltz's Adversity Response Profile was employed as instrumentin this study. The data was then analysed with the sum, median, mean, standard deviation, independent-sample t-test, and logistic regression.The findings of the study show that the majority of employees have a high adversity quotient score.In terms of gender, men employees tend to score higher than female employees. Employees aged 50 and over excel those aged 26 and below. However, the adversity quotient score for employees of different races is not significantly different. Employers should eventually take serious concern by implementing the appropriate intervention programme or policy aimed at potential employees in order to overcome their shortcoming in the adversity quotientand, more importantly, to enhance the employee's ability to face challenges in order to drive the company's mission and vision.
José Carlos Mariátegui: entre las políticas culturales y la gestión cultural
Authors: Vich Victor , Mariátegui E. José-Carlos
Published: April 2023

Este ensayo explora la faceta de José Carlos Mariátegui como observador de las políticas culturales del Estado y como gestor cultural desde la sociedad civil. Mariátegui fue un incansable fundador de periódicos y revistas, y promovió un tipo de producción editorial que estuvo marcada por novedosos modelos de sostenibilidad y difusión. Su objetivo consistió tanto en contribuir a transformar la cultura entendida como “modo de vida” como en proponer proyectos editoriales destinados a formar ciudadanos más informados, con nuevas ideas y con una sensibilidad distinta de la propuesta por la sociedad capitalista. Por ello, este artículo explora esta faceta poco estudiada del trabajo de José Carlos Mariátegui a partir de su práctica periodística, de su labor en el campo editorial –que abarcó la creación de la editorial Minerva y los modelos de sostenibilidad de Amauta y Labor–, y de su incesante preocupación por las políticas culturales en el Perú (entendidas como instancias de democratización de la cultura). Debido a ello, organizó una extensa red de contactos que aseguraran un eficiente sistema de difusión. Argumentamos que Mariátegui no solo fue quien produjo el pensamiento más original de la modernidad peruana, sino que, además, él fue un dinámico agente cultural en búsqueda de significativas transformaciones en el país.

In the context of regional development, regional development directions are needed based on the availability of resources, so that regional development directions can be directed and run well. In general, the goals of regional development are equity, economic growth, and sustainability so that the region can develop to the desired level. The ability to take advantage of the potential planning resources available in the region is a way of developing a region based on regional potential. One of the solutions in regional development is the development of superior commodities, with the intention that these commodities can support regional economic growth and people's welfare. The purpose of this study was to identify and determine the superior commodities of the plantation sub-sector in Rokan Hulu Regency and to determine the location of the superior production of the plantation sub-sector in Rokan Hulu Regency. Leading commodities are determined based on analysis of Sectoral Contribution Index (SCI), Growth Ratio Model (GRM), Dynamic Location Quotient (DLQ), Location Quotient (LQ) and Composite Indeks (CI). Meanwhile, plantations in plantation sub-sector superior production areas are carried out using a Geographic Information System with Hot Spot analysis Getis-Ord Gi*. Based on the results of the analysis, it is known that the leading commodities in the plantation sector in Rokan Hulu Regency are rubber and palm oil. Hot Spot analysis shows the location of the leading area, namely in North Tambusai District. The results of this study are expected to be input in determining the superior commodities of plantation estates and the development of agropolitan areas in Rokan Hulu Regency.
