Carbon emission and environmental cost from coal production in Indonesia
Authors: Mahroini Zahidah , Chien Yu-Lan
Published: July 2024

Indonesia primarily exports coal, with an average annual quantity of over 421 million tonnes in the past decades (2011-2020), reaching its peak at 616 million tonnes in 2019. Despite its economic benefits, coal production carries hidden costs. This research delves into using life cycle assessment (LCA) to gauge the environmental impact of coal production and estimate external cost (EC) related to Greenhouse gases (GHG) and air pollutants (AP). The study applied the benefit transfer method to make these estimations, focusing on coal mining and international transport processes. The findings revealed that over the past decades, per tonne coal mining contributed an estimated EC of $12.54-15.26 for GHG and $3,439-5,250 for AP, while transport abroad per-tonne-km coal incurred an EC of $19.98-23.94 for GHG and $19.58-23.30 for AP. Moreover, coal mining contributes to water pollution and substantial water depletion. Despite the coal production in Indonesia generating around $40 billion in revenue in 2020, the study shows that the total EC from GHG and AP is up to $2,131 billion, which is 53 times the revenue, posing serious health and ecological risks to Indonesians and exacerbating global climate change. Notably, these estimates exclude EC from water pollution (WP) and water depletion. With the global push towards ‘net zero emissions’, the coal industry as a whole faces an urgent need to curb its GHG and AP emissions from its.

Authors: Ostoj Izabela ,   University of Economics in Katowice
Published: July 2024

Goal – the article aims to identify the characteristics of platform work (PW) as a potential source of satisfaction, based on the opinions of adult Poles. It draws on the approaches to job satisfaction derived from neoclassical economics and psychological concepts of work. Research methodology – the characteristics of PW were compiled through the review of extant literature. The opinions were collected in a diagnostic survey using an online questionnaire filled and returned by a representative sample of 3165 Poles. The survey identified a group declaring to have the knowledge of platform-mediated work opportunities, which ultimately contained 2099 respondents. To the best of the author’s knowledge, this was the first survey in Poland on the perception of the characteristics of work mediated through digital platforms conducted on such a large scale. Score/results – the study showed that major benefits of PW relate to contractor autonomy and concern the freedom of choice when and how long to work. The most frequently identified demerit, on the other hand, concerns work remuneration and it is the instability of income. Originality/value – the originality of the study stems from the quantitative representation of the opinions concerning the characteristics of platform-mediated work, divided into merits and demerits classified under three categories: labour income, contractor autonomy, and working conditions.

Authors: Zagóra-Jonszta Urszula ,   The University of Economics in Katowice
Published: July 2024

Goal – the article analyzes the anti-crisis policy of the Silesian Sanation. In this challenging period for the economy, the Silesian provincial authorities had to counteract the crisis’s adverse effects and defend themselves against attacks from the opposition, mainly the Silesian Christian Democrats and socialists, who criticized their actions. Research methodology – source analysis, comparative, and description methods were used. This investigation is based on pre-and post-war studies on the discussed topic. Score/results – during the crisis years, the Silesian authorities extended the public works system and triggered the Polonization of the Silesian industry. Contrary to the central government, the active involvement of the state in economic life was accepted by the Silesian Sanation. The state was taking over indebted German enterprises because of the weakness of the Polish private capital. Originality/value – the article is based on source materials, i.e., Prints and Transcripts of the Silesian Parliament, materials from the National Christian Labor Union congresses, and the Sanation press. The Silesian Sanation stance towards interventionism was stated, which is often forgotten when writing about the government’s attitude (as a representative of the total authorities) to the state’s role in the economy.

Corporate Social Responsibility: Environmental Concern Through the Application of Communitarian Citizenship Thinking
Authors: Fahmi Rizal , Hilal Ramdhani  , Hudaya Latuconsina  , Sri Jaya Lesmana
Published: July 2024

Environmental awareness is an integral part of the sustainability of ecosystems worldwide that are starting to be damaged due to rapid industry. The rise of industrial companies in Indonesia impacts environmental damage and has drawn criticism from the community, so corporate social responsibility was formed, which is a form of corporate commitment to its social environment to maintain environmental sustainability and empowerment of the surrounding community. Ideologically, environmental damage is inseparable from the muscular liberalism that pays little attention to ecological elements. This paper seeks to raise an alternative study of communitarian CSR that understands environmental awareness. Communitarianism focuses on the social reality that must be maintained and cared for to raise collective consciousness, including environmental elements. This paper uses a literature study to examine the understanding of communitarianism. The knowledge gained from the literature search is that communitarianism provides a different perspective from liberalism regarding self and environment, so it is interesting to apply communitarian thinking in companies to implement environmental awareness as an alternative to solving environmental problems where this condition indicates the need for a movement based on communal awareness in reforestation. The more communal awareness of nature is built on the impact of community pressure on the government to make a rule that pays attention to environmental problems.

Published: July 2024

Aim: This study aimed to investigate the effects of ergothioneine and quercetin on the in vitro development of bovine embryos Materials and Methods: Cumulus-oocyte complexes (COCs) were collected via ovary aspiration from a local abattoir and cultured in vitro for maturation. After maturation, in vitro fertilization was performed. The pronuclear embryos were divided into three groups: control, 10 μM L-ergothioneine, and 10 μM quercetin supplemented. After the addition of antioxidants to the CR1aa medium, in vitro culture of embryos were performed. The cleavage and morula rates were assessed on days 2 and 5, respectively. Blastocyst formation and quality were assessed on days 7-8. Results: Statistical analysis showed cleavage and morula rates were significantly higher in the ergothioneine group compared to the quercetin and control groups (P<0.05). While no blastocysts formed in the quercetin group, the blastocyst rate reached to 17.96% with ergothioneine supplementation on day 8. Conclusion: In conclusion, supplementation with 10 μM ergothioneine enhanced the in vitro development of bovine oocytes. However, 10 μM quercetin supplementation impaired development, and no blastocyst formation observed. Further studies utilizing different concentrations are warranted to better understand the effects. This study provides insights into modulating oxidative stress during in vitro embryonic production.

Published: July 2024

An algorithm for analyzing double-crystal rocking curves from the near-surface layers of monocrystals has been proposed, and corresponding software has been developed. It is taken into account that to obtain correct results, both coherent and diffuse components of X-ray scattering need to be considered. The possibility of simultaneous analysis of rocking curves from several reflections is provided. To approximate experimental rocking curves with theoretical ones, an approach that simultaneously uses three different approximation methods has been utilized. The effectiveness of the proposed approach is confirmed by verifying the uniqueness of the obtained results.

Published: July 2024

В задаче рассеяния света одиночной случайно ориентированной частицей пик обратного рассеяния для крупной частицы неправильной формы связан с известным пиком когерентного обратного рассеяния. Показано, что степень линейной поляризации вблизи направления рассеяния назад для одиночной частицы имеет всплеск, физической причиной появления которого является то же самое когерентное обратное рассеяние. В приближении физической оптики нами рассчитано обратное рассеяние света крупными хаотически ориентированными частицами неправильной формы. Показано, что знак всплеска поляризации для пар сопряженных пучков может быть как отрицательным, так и положительным в зависимости от формы траектории пучков света, которые вносят основной вклад в обратное рассеяние. Суммируя всплески, мы приходим к выводу, что общеизвестные явления отрицательной поляризации не обязательны для случая одиночной частицы, рассеивающей свет в окрестности направления рассеяния назад. Результаты работы будут полезны для интерпретации данных, получаемых российскими и международными лидарными сетями.

In this article, we have calculated light backscattering by large irregularly shaped particles with random orientations. We have utilized the physical optics approximation to analyze this phenomenon. Our findings demonstrate that there is a distinct polarization surge in the degree of linear polarization, which arises from coherent backscattering. The sign of the polarization surge for pairs of conjugate beams can vary, being either negative or positive, depending on the light beam trajectorie which significantly contribute to the backscattering process. By summing up these surges, we have concluded that the well-known phenomenon of negative polarization not necessarily occur when a single particle scatters light in the vicinity of the backscattering direction.

Published: July 2024

Расширение грозопеленгационных сетей в последнее время привело к росту количества данных о грозах, которые могут использоваться для верификации прогнозов гроз и являются новым источником информации о состоянии атмосферы. Эта информация может быть учтена в численных моделях динамики атмосферы, но на данный момент применяется весьма редко. В работе предложена и реализована в виде кода в рамках модели WRF-ARWуниверсальная процедура учета данных о положении гроз. Процедура универсальна, так как не требует использования каких-либо процедур параметризации физических процессов, и благодаря этому она может быть введена в любую гидродинамическую модель. В процедуре по данным сетей грозопеленгации определяются ячейки расчетной сетки, в которых фиксировались молнии, в них итерационно добавляется влага до возникновения термодинамической неустойчивости, а значит конвекции. Исследована эффективность этой процедуры в прогнозе осадков, температуры и влажности; проведено сравнение с другими способами учета данных о грозах. Усвоение данных грозопеленгаторов позволяет локально улучшить прогноз сильных осадков и температуры в областях, где наблюдались грозы; коэффициент прогноза интенсивных осадков Пирси–Обухова при использовании предложенного метода возрастает с 0,26 до 0,40.

The paper considers the possibilities of taking into account data from lightning networks in the procedure for lightning data assimilation in numerical models of atmospheric dynamics. A universal procedure is proposed and the code is implemented within the framework of the WRF-ARW model. According to the data from lightning detection networks, the cells of the computational grid are determined, in which lightning was recorded. Then moisture is iteratively added in these cells until the occurrence of thermodynamic instability and, hence, convection. The effect of using this scheme on the forecast of precipitation, temperature, and humidity is studied, and a comparison is made with other lightning assimilation methods. The use of data from lightning detectors makes it possible to locally improve the forecast of heavy precipitation and temperature in areas where thunderstorms were observed. The Piercy–Obukhov coefficient for forecasting intense precipitation using the proposed procedure increases from 0.26 to 0.40.

Published: July 2024

The flexural performance of a glulam wood/PVC composite (GWPVC) hollow member, which was assembled from four elements with WPVC composite hollow sections to create a double I-section, was studied using two methods: the analytical method with iteration technique (AMIT) and the finite element method (FEM). Experiments verified the predictions from AMIT and simulations from FEM to determine the most suitable method for the parametric studies. This investigation explored the variations in slenderness ratio and the flange and web thickness to enhance and study their impact on flexural performance. In parametric studies, equal cross-sectional areas were used to facilitate comparisons and maintain production costs. The importance of bond strength at the contact surfaces in assembling a GWPVC hollow member led to bonding tests and confirmed sufficient strength at contact surfaces. In four-point bending tests, the GWPVC hollow member exhibited a brittle mode with flexural tensile failure without delamination. The initial MOE, MOR, and maximum deflection values were 5,140 MPa, 29.8 MPa, and 47.8 mm, respectively. The parametric study employs AMIT to investigate flexural performance and reveals that varying the slenderness ratio affected the initial stiffness, maximum deflection, and ultimate load. Flexural performance can be improved by making minor adjustments.

Published: July 2024

Water contamination in rural Malaysian areas, mainly caused by logging activities leading to soil erosion and river pollution, presents a significant threat to water supplies. In response, a specialized activated carbon water filtering device was developed to target the absorption of organic molecules. The impact of compaction of activated carbon on water filtering efficiency was evaluated. Testing both compacted and uncompacted activated carbon filters with contaminated river water, the study utilized the Malaysia Department of Environment’s (DOE) water quality index (WQI) to assess filter effectiveness. The results revealed that water filtered through compacted activated carbon was clearer and less yellowish compared to the uncompacted counterpart. Moreover, the compacted filter showed higher dissolved oxygen levels, lower ammoniacal nitrogen levels, and a lower pH, resulting in a significantly higher WQI score of 80.4 compared to 78.8 for the uncompacted filter. Further analysis via an adsorption isotherm test demonstrated the superior ability of compacted activated carbon to absorb acetic acid, as evidenced by higher lines in the Freundlich isotherm model graphs. These findings emphasize the efficacy of compacted activated carbon in water filtration, advocating for its integration into filter construction to enhance water quality in rural regions.

Published: July 2024

Global regulations are guiding society towards more sustainable material solutions. This increasing awareness of the need for environmentally friendly alternatives has led to a greater emphasis on biocomposites, which combine natural fibers with bio-based polymers. This study investigates how bleached softwood pulp fibers (BSWPF) and unbleached softwood pulp fibers (UBSWPF) affect the characteristics of poly(lactic acid) (PLA)-based biocomposites. UBSWPF is a more cost-effective option because it is manufactured with less processing steps than BSWPF. However, it is largely unexplored as a reinforcement in biopolymers. Through investigating the mechanical, thermal, and morphological aspects of the biocomposites, this study showed that UBSWP increased the modulus and impact strength of the PLA biocomposites better than BSWPF. The impact strength, modulus, and tensile strength of PLA-BSWPF and PLA-UBSWPF improved as the fiber content increased. However, a decrease in tensile strength was seen at higher percentages of UBSWPF in PLA. Despite the decrease in tensile strength at higher UBSWPF concentrations, both types of fibers improved the mechanical properties of the biocomposites, demonstrating a potential sustainable reinforcing material for PLA biocomposites.

To address the current inefficiencies and subjective nature of manual observation in maize cultivation, with the aim of achieving high efficiency and productivity, this study focused on the DeMaya D3 maize variety. It proposes a maize growth stage recognition method based on the MobileNet model, which is a lightweight convolutional neural network architecture. The method was tested and achieved recognition accuracies of 0.98, 0.96, 0.92, 0.85, and 0.97 for different growth stages, respectively. Additionally, a maize growth prediction model was developed. Based on data collected from experimental plots regarding maize plant height and stem diameter, the Prophet model and an optimized version of the Prophet model were used to forecast maize growth trends. The Prophet model is an open-source tool for time series forecasting. Comparative analysis was conducted between the predictions of the original Prophet model and the optimized version. The relative errors of the Prophet model predictions were 0.85%, 2.11%, and 0.79%, while those of the optimized Prophet model were 0.76%, 0.47%, and 0.71%. Compared to the Prophet model, the optimized model reduced errors by 0.09%, 1.64%, and 0.08%, respectively. The maize plant growth control system was designed to obtain the information through the collection layer. The decision-making layer judged the soil nutrient absorption and growth status. Finally, the management layer controlled water and fertilizer.

The goal is to investigate and evaluate the effects of FES and TENS, individuals who have suffered spinal cord injury, spasticity of paresis or plethora leg muscles, and muscle characteristics. The study was conducted in the homes of the persons. Before and after stimulation, spasticity and muscle properties were measured using the myotonometer “Myoton”. Using Compex Cefar and Compex Mini stimulants, 30 min. FES was applied to the left leg and 30 min. of the TENS program to the right leg. The study involved 10 individuals who suffered spinal cord injury. Tens showed a statistically significant increase in the elasticity of the quadriceps thigh muscle (p < 0.05), which means that the ability of the muscles to resist muscle contraction and the effects of external factors increased. All other measurements did not have a statistically reliable difference (p > 0.05). No statistically significant difference was also found between the FES and TENS groups (p > 0.05). Although FES and TENS did not have a statistically significant impact on elasticity and muscle tone, tens had a statistically significant deterioration in the muscle property of elasticity, which means that spasticity increased.

Published: July 2024

The present study is a contribution to evaluate the agronomic potential of two different organic products (cattle effluents, either composted or digested by Black Soldier Fly larvae) as organic fertilizers, through the measurement of production and the photosynthetic activity of ryegrass (Lolium multiflorum L.), growing in a sandy soil, treated with different doses of those products. Within this aim, an experiment was conducted in a semi-controlled greenhouse with ryegrass plants cultivated in pots, with ten treatments: four different treatments of traditionally composted material, four different treatments of biodigested material, a mineral control (using the recommended rate of mineral fertilizer for ryegrass), and a zero control (without any type of fertilization). Under the experimental conditions, the results showed a significant effect of both organic composts over mineral fertilization, with a better performance of the biodigested by black soldier fly larvae. As for the informative capacity of photosynthetic activity data, in assessing the vegetative development of crops, "net assimilation rate" and "water use efficiency" proved to be the most suitable parameters.

In the Republic of Moldova, the issue of the child labour in agriculture presents a significant challenge. This study has the aim to evaluate the participation of the Moldovan children in agricultural work and its effects on their well-being, safety, and education. Highlighting a lack of updated data and research within Moldova, especially in the agricultural sector, this study employs a detailed methodology encompassing national statistics, expert surveys, and international convention reviews. The findings indicate the involvement of children in various agricultural tasks, including hazardous ones, affecting their education and health, with children aged on average 12.7 to 15.3 years working over 20 hours weekly. The research distinguishes between harmful child labour and beneficial work, advocating for a comprehensive strategy to improve educational opportunities, family incomes, and alternative employment options. It stresses the importance of effective policies and legislation to safeguard children from exploitative labour in both formal and informal sectors. Although there has been some advancement in tackling child labour in Moldova, considerable obstacles persist. The research advocates for a comprehensive strategy that includes refining policies, strengthening the enforcement of current laws, and executing specific initiatives aimed at decreasing child labour in the agricultural sector. The research calls for joint efforts from the government, international bodies, NGOs, and communities to protect and promote child welfare, aiming to integrate children into safe environments and offering them better future prospects.

Photoluminescence of aluminum nitride films at the below bandgap excitation has been studied. It has been found that low-energy (up to 2.02 eV) photoluminescence spectra of the AlN films contain a series of equidistant maxima, the intensities of which decrease with energy. Theoretical analysis has shown that the observed photoluminescence features may be caused by strong electron-phonon interaction (long-range interaction of electrons in the band gap with Al3+ ions in the lattice sites). This interaction presumably leads to appearance of quasi-particles in the band gap of AlN, which are a bound state of an electron with an ion in a crystal lattice site. Such quasi-particles have been called “elions”. The energy of an elion is quantized. An elion quantum is equal to the longitudinal optical phonon energy. The low-energy photoluminescence is based on the elion generation and subsequent annihilation mechanism.

AbstractThis research aims to discover what and how culture is represented in the "Bahasa Inggris 2" textbook. A qualitative descriptive method was employed in this paper, focusing on documents as the primary data, in which nine chapters were analyzed utilizing a checklist of content analysis. The findings reveal three aspects of culture: cultural categories, elements, and senses. First, following the concept of Cortazzi & Jin (1999), three cultural categories, i.e., source culture, target culture, and international culture, were found in the textbook. Second, cultural elements based on Yuen (2011), i.e., products, persons, perspectives, and practices were observed. Finally, referring to Adaskou et al. (1990), the senses of culture included in the textbook were aesthetic, sociological, semantic, and pragmatic. Concerning the frequency of occurrence, the research results show that the cultural categories were mostly present through source culture (42.75%), whereas the cultural element was dominated by products (48.31%). Lastly, the sociological sense was found to occur the most (44.44%). These findings imply the need to have a balanced representation of the three mentioned cultural aspectAbstrakPenelitian ini bertujuan untuk menemukan apa dan bagaimana budaya direpresentasikan dalam buku ajar “Bahasa Inggris 2”.

Published: July 2024

Background: Heart failure with mildly reduced and reduced ejection fraction are associated with incident cancer. However, cancer screening is not routinely discussed in this population. This study aimed to describe the uptake and perception of cancer screening among patients with heart failure attending a specialised heart failure clinic in Australia. Methods: A prospective survey of consecutive ambulatory patients attending the clinic from 2022–2023 was performed. Included patients were eligible for recommended breast, cervical and/or bowel cancer screening according to Australian guidelines, had an ejection fraction of <50% and no prior history of cancer. The primary endpoint was adherence to recommended cancer screening according to Australian guidelines. Perceptions towards cancer screening were also assessed and cancer screening rates were compared with those of the general Australian population. Results: Among the 200 included patients, there was low uptake of recommended breast, bowel and cervical cancer screening despite the availability of free national cancer screening programmes. Cancer screening rates among heart failure patients were lower than observed in the general Australian population. Patients were unaware of the association between cancer and heart failure and expressed interest in cancer screening participation. Conclusion: Future efforts should be targeted at improving education on cancer screening among patients and cardiovascular healthcare providers to improve overall health outcomes in heart failure.
