Authors: Nisa Roudhatun , Gazali Ahmad , Anafarhanah Sri 
Published: October 2022

Pengelolaan wakaf yang baik sangat dipengaruhi oleh nazir selaku pengelola, penerapan fungsi POAC dalam lembaga nazir sangat penting dilakukan guna meningkatkan kualitas SDM dan nilai dari wakaf. Metode penelitian ini adalah kualitatif dengan jenis penelitian lapangan. Hasil dari penelitian mengatakan bahwa nazir di kecamatan Penajam didominasi oleh nazir yang berlatarbelakang pendidikan SLTA, kemudian penerapan fungsi manajemen sumber daya manusia pada (a)perencanaan, sistem pemilihan nazir telah sesuai dengan undang-undang (b)pengorganisasian, pembentukan struktur, pengembangan SDM melalui pelatihan, serta kompensasi non finansial (c)pelaksanaan yaitu dimulai dari administrasi hingga pengelolaan wakaf sesuai dengan peruntukkannya, dan (d)pengawasan, dilakukan langsung oleh kementerian agama dan KUA. Dari hasil diatas penerapan manajemen sumber daya manusia pada nazir masih belum terlaksana dengan baik karena kurangnya pelatihan sehingga menyebabkan kurangnya pengetahuan nazir terhadap wakaf serta pengelolaan yang masih bersifat tradisional, akan tetapi secara garis besar pengelolaan wakaf dikecamatan Penajam bisa dikatakan efektif karena pengalaman yang dimiliki nazir.

Mining waste due to gold exploitation has a great consequence for the environment and needs to be assessed where mining sites are developed for good sustainable environmental management because it is responsible for the release of massive amounts of hazardous metals. For this purpose, the diagnosis of the current state of the environment of the mining sites of Fel and its environs was carried out through physical and geochemical analysis to assess evidence of pollutant capacity. Physical analyses focus on the granulometry of wastes while geochemical analyses concern the assessment of the amount 10 Metallic trace elements (MTE) on 9 samples from three mining sites. The results of the granulometric analyses reveal heterogeneity and discontinuity in the sandy gravel texture of the waste. Geochemical analyses show that a fine fraction less than 80 μm presents the best geochemical result for all chemical elements. The geoenvironmental assessment of the wastes according to the Geoaccumulation Index (Igeomax=7,14), the Contamination Factor (CFmax=212,45), the Degree of Contamination (DCmax=252,86) and the Sediment Pollution Index (SPI), characterized by low polluted sediment (SPImax=4,07), made it possible to establish the high link between As and Sb with very high concentrations, thus extreme pollution of these elements in the mining waste of the study area, particularly in Foum, Mama Wassande and Fel. Strong to very strong positive correlations observed between As and Cu, Pb, Cd and Cr, suggest that these MTE originated from a common source of contamination. Therefore, these MTE should be assessed on groundwater to prevent and avoid or minimize their effect on human health in this environment.

COVID-19 pandemic generated copious amounts of news regarding COVID-19 that is circulating among the public. Both positive (e.g., vaccine development) and negative (e.g., COVID-19 cases increase) news affect emotional states on an individual level, specifically for the student in higher education. They are struggling in challenging situations while adapting to online learning, which is not easy for them. This study aims to gain knowledge and gather empirical data on the COVID-19 news impact on young adult students in one of the public universities in West Java, Indonesia. We used an experimental approach in this study. Sixty participants were randomly assigned into control and experiment (i.e., being exposed to COVID-19 news) groups. Positive Affect Negative Affect Schedule was used to measure participants' emotional state before and after the experiment. This study shows that COVID-19 news significantly decreases participants’ positive affect when participants have personal experience with COVID-19. Therefore, information sharing regarding COVID-19 has to be done with caution to protect individual emotional states during the pandemic. The student also should restrict the abundant information relating to COVID-19 to maintain their positive emotional state.

Published: October 2022

Abstract
This paper presents a neural network model for identifying non-human traffic to a web-site, which is significantly different from visits made by regular users. Such visits are undesirable from the point of view of the website owner as they are not human activity, and therefore do not bring any value, and, what is more, most often involve costs incurred in connection with the handling of advertising. They are made most often by dishonest publishers using special software (bots) to generate profits. Bots are also used in scraping, which is automatic scanning and downloading of website content, which actually is not in the interest of website authors. The model proposed in this work is learnt by data extracted directly from the web browser during website visits. This data is acquired by using a specially prepared JavaScript that monitors the behavior of the user or bot. The appearance of a bot on a website generates parameter values that are significantly different from those collected during typical visits made by human website users. It is not possible to learn more about the software controlling the bots and to know all the data generated by them. Therefore, this paper proposes a variational autoencoder (VAE) neural network model with modifications to detect the occurrence of abnormal parameter values that deviate from data obtained from human users’ Internet traffic. The algorithm works on the basis of a popular autoencoder method for detecting anomalies, however, a number of original improvements have been implemented. In the study we used authentic data extracted from several large online stores.
Rotors of Vertical-Axial Wind Turbines Assembled in Bearings and Aerodynamic Characteristics of a Blade with Unclosed Wing Profile
Authors: Panda Anton , Rozhkova Lyudmila , Kuznetsov Eduard , Nahornyi Volodymyr 
Published: October 2022

Abstract
In world practice, traditional blades used in high-speed wind turbines, both horizontal-axial and vertical-axial, have a wing-shaped profile. However, for horizontal-axial wind turbines, blades with such a profile have a fairly narrow range of operating values of the angle of attack of the incoming air flow and a low value of the moment of pulling from place. As for vertical-axial wind turbines, the self-starting of the rotor with wing blades is completely absent and additional devices are needed to start the rotor into operation. In order to ensure the self-starting of the rotor and the operation of the wind turbine at high and low wind speeds, a new shape of the blade profile was developed, called non-closed wing profile. The concept of the development is that the blade should have a configuration in which the pulling force is involved at the beginning of the movement, and then, with the establishing of the movement, a lifting force would arise, which acquires a prevailing character in the operating mode. The article presents the results of experimental studies of the aerodynamic characteristics of the developed non-closed wing blades. One of the results obtained is to determine the effect of the thickness of the blade profile on the range of values of subcritical angles of attack of the incoming air flow and the differences between the nature and range of changes in the coefficients of lifting force and pulling force in a traditional wing blade and a blade with a non-closed wing profile. Studies of the rotor model of a vertical-axial wind turbine with non-closed wing blades have confirmed the presence of its self-starting and operability even at low wind speeds.
E-Service Quality Assessment According to Hierarchical Service Quality Models
Authors: Ingaldi Manuela 
Published: October 2022

Abstract
E-commerce is becoming more and more popular. The COVID-19 pandemic made its development even faster. Currently, an enterprise that does not provide its services via the Internet is suffering heavy losses. Online shopping is largely different from traditional purchases, so their assessment should be made on the basis of different criteria. The aim of the paper was to assess the quality of services provided by the selected e-shop, in terms of its commercial services. The first stage of the research was the analysis of the literature in terms of hierarchical models of e-service quality, which in their structure indicate the areas of assessment. This allowed for the construction of the author’s hierarchical model of e-services and for making a list of attributes that were used in further research. On the example of the clothing e-shop, an analysis of the provided services was made, taking into account the opinions of its customers. The Importance Performance Analysis (IPA) was selected as the basis for conducting the survey research and analyzing its results, which facilitates the commenting of the obtained results. The research allowed to indicate the strengths and weaknesses of the examined e-shop, but also to identify areas requiring improvement in order to increase the quality of the offered services, as well as the customers satisfaction.

Abstract
Companies are increasingly aware that employees are an important factor in success, so they pay more and more attention to them. Because of that, organizational culture and normative commitment are also included as extremely important factors. The research includes a systematic and comprehensive review of the literature and at the same time obtaining and analysing data from practice through a survey. The research focuses on employees from the logistics departments in the supply chain of electronic component production and supply. Group of companies across Europe were included in the survey (Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Germany, Hungary, Latvia, Lithuania, North Macedonia, Poland, Romania, Russia, Serbia, Slovenia and Ukraine). The research demonstrates the realization that the types of classification of organizational culture have different effects on direct and indirect normative commitment. Gender differences were also found. The research-based on the calculated average mean values shows the classifications of organizational culture and normative commitment. The latter follows the organizational culture with minor deviations. The order of classification of organizational culture follows the current economic situation, where according to the studied criteria, the first is a culture of the market. The research shows that men’s rate of normative commitment is better than women’s, while in organizational culture the situation is exactly the opposite. One of the most significant findings is based on the Pearson correlation coefficient with the SPSS program was found that, according to the classification, Hierarchy culture has a positive effect on indirect normative commitment.
The Impact of Psychophysical Factors on the Level of Occupational Risk in Small-Sized Enterprises with Particular Emphasis on the Manufacturing Sector
Authors: Niciejewska Marta , Idzikowski Adam 
Published: October 2022

Abstract
In this paper, the authors focused on the analysis and evaluation of factors affecting the level of occupational risk in “small” enterprises, with a particular emphasis on psychophysical factors in the manufacturing sector. The study was conducted using a self-administered questionnaire. The results were verified using the strucla interview method with elements of observation. The purpose of the paper was to draw attention to – often overlooked in the assessment of occupational risks by employers – psychophysical hazards with particular emphasis on psychosocial hazards. Respondents – employees of enterprises with a particular focus on the manufacturing sector – point to psycho-physical hazards as those that, right after hazardous (accident) hazards, significantly affect the level of occupational risk. However, the assessment of factors determining the level of occupational risk changes with the age of respondents. Older workers, more often than younger ones, perceive the factors that affect the level of occupational risk. Their experience and ability to reliably identify risks can be very useful in creating awareness of safe behavior among the youngest workers, who are most vulnerable to occupational accidents. The article also presents analyses and assessments of the symptoms of occupational stress, which is one of the factors shaping psycho-physical risk that is so often underestimated by many workers and employers.

Published: October 2022

Abstract
The study explored the legislative database for the maritime sector to be sustainable and have an intact blue economy. The problem for organizations with shipowners that have fishing boats older than 20 years is stated. Decision-making authorities face challenges nowadays. To be in the fleet for the next decade, shipowners for their ships should deploy energy efficiency projects for marine system retrofitting to improve energy efficiency and meet environmental regulations. The Ship Energy Efficiency Management Plan’s development principles are discussed due to the current need for its deployment from 2021, so shipowners can contribute to the fast adoption of new regulations by the International Maritime Organization. In this work it is being offered to incorporate energy management issues with guidelines for upcoming regulations as well as those that are currently enforced. To improve energy efficiency, reduce environmental impact and cut fuel consumption costs, marine system retrofitting has been proposed. In this paper the focus is being put on studying energy management strengths and weaknesses which can lead to a qualitative understanding of the performance of the organizational structure, this work also focuses on the management settings concerning energy efficiency. If the organization wants to win by integrating energy policy, high-quality communication or promotion of energy efficiency issues should be employed. Marine plastic debris challenges fishing carriers on the African Union route. A possible beneficial solution for shipowners is discussed in this study.

Published: October 2022

Abstract
The article considers the methodological aspects of the theoretical investigation of marine power plants with thermochemical fuel treatment. The results of the study of the complex influence of temperature, pressure, and the ratio of steam / base fuel on the thermochemical treatment efficiency are presented. The adequacy of the obtained regression dependences was confirmed by the physical modelling of thermochemical fuel treatment processes. For a gas turbine power complex with a thermochemical fuel treatment system, the characteristics of the power equipment were determined separately with further merging of the obtained results and a combination of material and energy flow models. Algorithms, which provide settings for the mathematical models of structural and functional blocks, the optimisation of thermochemical energy transformations, and verification of developed models according to the indicators of existing gas turbine engines, were created. The influence of mechanical energy consumption during the organisation of thermochemical processing of fuel on the efficiency of thermochemical recuperation is analysed.

Published: October 2022

Abstract
This article presents the influence of various ship’s operational conditions occurring during manoeuvres related to entering and leaving the ports and mooring operations. Frequent starts and stops of the ship’s propulsion unit are then required, which affect the variability of the energetic loads of the ship’s power plant, causing accelerated, non-design wear of the ship’s main propulsion engine. The effects of cold start-ups of the main ship engine are the subject of this study. Conditions of the engine inlet valve damage process are discussed. The physics of the degradation process leading to air inlet valve damage was considered. Laboratory tests of structure continuity and their results are discussed, and the valve material defects were excluded as the cause of the damage. The causes of repeated damage to the inlet air valves were identified. The effectiveness of the performed corrective measures was confirmed by a documented control test of the engine start-up. The article is a utilitarian premise for the requirements of the Classification Society.

Published: October 2022

Abstract
A marine gas turbine enclosure must be designed to prevent overheating of the electrical and engine control components as well as diluting potential fuel leaks. In order to achieve an optimal enclosure design, a numerical study of the ventilation-ejection cooling mechanism of a gas turbine enclosure is carried out in this paper. The evaluation index of the ejection cooling performance is first proposed and the algorithm of numerical simulation is verified. On this basis, orthogonal combinations of structural parameters are carried out for the expansion angle α of the lobed nozzle and the spacing S between the outlet plane of the lobed nozzle and the inlet plane of the mixing tube. The flow and the temperature distribution inside the enclosure are analysed under different operating conditions. The results show that the influence of the lobed nozzle expansion angle α and the spacing S on the performance is not a single-valued function but the two influencing factors are mutually constrained and influenced by each other. For any spacing, the combined coefficient is optimal for the expansion angle α = 30°. When the expansion angle α = 45° and the spacing S = 100 mm, the combined coefficient and the temperature distribution inside the enclosure are optimal at the same time.

Esta investigación tiene como objetivo central comprender la seguridad alimentaria en Brasil ante el desperdicio de alimentos en la cadena productiva, y verificar las perspectivas de mitigación para el cumplimiento de los Objetivos de Desarrollo Sostenible, especialmente en cuanto al hambre. El desperdicio de alimentos empieza con el manejo, almacenamiento y acondicionamiento, debido a la ineficiencia de las cadenas de abastecimiento y de procesamiento, distribución y consumo. Al esperdicio de alimentos se le añaden los impactos socioambientales por el uso del agua, en el suelo y en la biodiversidad, que impiden la solución del hambre, teniendo en cuenta que la alimentación adecuada y la existencia de una producción suficiente de alimentos constituyen un derecho humano fundamental. En ese contexto, se plantea como problema de investigación el siguiente interrogante: ¿cuáles son las perspectivas de mitigación del desperdicio de alimentos a lo largo de la cadena productiva para el cumplimiento de los ods?
Undergraduate medical education in India: Need for total modification
Authors: Ghosh Kanjaksha 
Published: October 2022

Background:
With tremendous advances in medical and allied sciences and India passing through epidemiological transition, the need for overhauling undergraduate medical education was felt in the past 30–40 years. Around the world, both developed and developing nations felt similar needs. The present review evolved from the quest of how to overhaul medical education in our country.

Methods:
All the references on medical education with key words such as teachers, Reforms, challenges, undergraduate teaching, qualities of good medical teachers, infrastructural requirements, and curriculum generation were taken out from “PubMed” published after January 1980. These articles were carefully read and summarized in this narrative review. The references which authors found most relevant for Indian undergraduate education and some perspectives on what the world is thinking about medical education in general are included in the study.

Results:
Undergraduate medical education in India is in dire need of overhauling and this should start with preparing students from the high schools for good medical education. Morality, ethics, empathy, and social awareness should be inculcated from the schools in addition to good scientific education and communication capabilities. After developing proper selection process, the undergraduate medical students should undergo need-based dynamic curriculum with both theoretical and practical training in a college having proper infrastructure and teachers who have been trained in education technology. The overseeing body needs to be corruption fee and should regularly oversee the progression of teaching. This body must liaise with university, state, and central government so that colleges are provided with everything required. Cost of medical education is high and there should be mechanism to smoothen this burden on the student. Student should learn at not only Individual patient management but also should have broad idea of epidemic investigation, community health, leadership qualities, and should learn elements of medical research. Students may be allowed to learn in his own pace within limits of time frame and training in silos must give away to broad-based interactive learning using all the learning tools including e-learning facilities.

Conclusion:
There is a need for global overhaul of undergraduate medical education of India with emphasis on assessment of outcome than mere theoretical learning. A teacher should act as a mentor during the whole of medical training period.
