Authors: Suprihatiningrum Jamil
Published: March 2024

There is no one-size-fits-all answer to support the uniqueness of a student’s learning needs. Providing accessibility to enable every student to achieve the same learning goals is a critical issue to create an inclusive environment. This study investigated ways of science teachers met the challenges in providing accessibility for students in learning science. Ten participants from three Schools Providing Inclusive Education (SPIE): Schools Cerdas, Pintar, and Pandai in basic education level in the Province of Daerah Istimewa Yogyakarta Indonesia were selected purposively. The participants were interviewed individually and in group to share their thought and experiences in meeting the challenges of learning accessibility for students with disabilities (SWD) in the science classrooms. As part of a qualitative case study, data were analyzed systematically and three themes were generated to discuss the findings, i.e., inclusive pedagogy, inclusive content, and inclusive technology. All participants considered how learning is achieved and provided the means to help students succeed. A syllabus was made available in all schools, although expectations were set low and learning objectives were not clearly defined and measurable. Collaborative teaching only existed in School Pandai with limited co-planning time. All teachers revisited science content and ensured it was set up for all students to meet their expectations. Science teachers in School Pandai created different worksheets based on the student’s needs as the main learning source, while other teachers in Schools Cerdas and Pintar claimed they had no time to vary science modalities. Although all teachers understood how SWD needs to interact with different tools, only teachers in School Pintar and Pandai utilized assistive technologies to help SWD in learning science.

Published: March 2024

This study explores the metacognitive dimensions of social media consumption among elementary school students in Islamic boarding schools, explicitly focusing on self-reflection and self-regulation. With the increasing integration of social media platforms in educational settings, understanding how elementary school students navigate and make sense of digital media becomes crucial. Metacognition, which involves the awareness and regulation of one's thinking and learning processes, plays a significant role in students' interactions with social media. The study adopts a mixed-methods approach, combining a comprehensive review of existing literature, empirical research, and interviews with students and educators in Islamic boarding elementary schools. The theoretical frameworks of metacognition and social cognitive theory inform the research design and analysis. The study reveals the metacognitive processes associated with social media consumption in Islamic boarding elementary schools. Students self-reflect by critically examining the content they encounter and assessing its relevance to their learning objectives and Islamic values. Additionally, self-regulation strategies, such as setting limits on social media usage and managing online distractions, are employed to maintain focus and ensure responsible digital engagement. The implications of this study highlight the importance of integrating metacognitive skill development within elementary education. Educators and stakeholders can use the findings to design interventions promoting self-reflection and self-regulation in students' social media usage. In conclusion, this study comprehensively explores the metacognitive dimensions of social media consumption in Islamic boarding elementary schools.

Published: March 2024

In the era of Intelligent Society 5.0, collaborative skills, which can be defined as the ability to work effectively with others to achieve common goals, are essential competencies for students to thrive. Therefore, this study aims to explore the effectiveness of Online-based Science Project Learning (SPL) as a substitute instructional model for fostering collaborative skills among elementary school students. The study participants consisted of 75 elementary school fifth-grade students, distributed across three classes in Muhammadiyah Islamic Elementary School, Surabaya, East Java, Indonesia. It is important to comprehend that this examination was a replica of a preliminary test, and was conducted following the same methodology without the inclusion of a control group. The study design utilized a single-group approach, incorporating both a pretest and a posttest assessment. Furthermore, data analysis was conducted through paired t-test, n-gain calculation, and ANOVA using IBM SPSS version 25. The obtained results showed a statistically significant increase in the collective proficiency score of the observed students, as assessed at a 5% alpha level, after their engagement with the online-based Science Project Learning (SPL) model. Additionally, the average n-gains for the three grades were high, with no grade-level differences, and over 90% of the students responded positively to the online-based SPL Model teaching method. Based on these findings, it was concluded that online-based SPL models improved the collaborative work skills of the observed students. This study has several implications. First, it enhances the understanding of 21st-century life skills and abilities among elementary school teachers in Indonesia. Second, it suggests the potential for expanding the scope of the subject matter. Third, it underscores the importance of government collaborations in studies that prioritize the development of 4C skills, particularly collaboration, among students. Moreover, the study also emphasizes the necessity of online-based Science Project Learning (SPL) for scholars interested in remote learning, with a focus on examining the collaborative abilities and science learning outcomes of elementary students in virtual learning environments.

Authors: Zhao Bin , Anas Nirwana
Published: March 2024

Traditional games must be adapted for the present since they have cultural values that need to be conserved for future generations. This study attempts to create an EFAS (Engklek Fun and Smart) medium version of a typical game product. With research experience at IES Al-Ittihadiyah Berastagi, this study applies the Research and Development (R&D) technique. Forty-five first graders of Islamic Elementary School (IES) Al-Ittihadiyah Berastagi became the study participants. The findings indicate that the EFAS medium is recognized as valid. The "Very Valid" category showed an 89.63% score for the EFAS medium. It is also claimed that the EFAS medium is useful. This information came from a survey of the students and teachers’ opinions. Twenty-five students completed a questionnaire on the EFAS medium, and the questionnaire received 9.6% in the "Very Practical" category. A score of 97.5% in the "Very Practical" category came from the teachers’ response to the supplied statement. The results of the two questionnaires indicate that the teachers and students’ replies are categorized as being very practical. Third, the EFAS medium is deemed operational. This was demonstrated by the fact that the students were able to respond to the ASK and DO question instruments both in writing and orally with a score of 92% during the learning process utilizing EFAS. Written responses to EFAS infer that it can be an "effective" medium, whereas oral responses indicate that the medium can help students develop their communication abilities. This justifies the declaration that the EFAS medium is legitimate, applicable, and useful for enhancing students' communication skills.

Ketenagakerjaan merupakan bidang yang vital dalam pembangunan ekonomi maupun pembangunan manusia. Dewasa ini, problematika terkait ketenagakerjaan semakin kompleks dan menjadi tantangan dunia. Sustainable Development Goals  menyoroti secara khusus peningkatan kualitas ketenagakerjaan, tertuang dalam tujuan kelima, yang secara lebih spesifik menggarisbawahi kelayakan pekerjaan. Sampai tahun 2030, dunia menargetkan kelayakan pekerjaan penuh yang diimbangi dengan menurunnya tingkat pengangguran. Pengangguran merupakan suatu fenomena yang banyak mendapatkan sorotan dan merupakan isu strategis dalam pemerintahan suatu negara. Di Indonesia, Tingkat Pengangguran Terbuka telah mencapai level yang setara dengan pengangguran global. Meskipun demikian, masih terjadi ketimpangan antarprovinsi. Penerapan program dan kebijakan yang sesuai dengan karakteristik ketenagakerjaan provinsi diperlukan untuk mengatasi ketimpangan serta mewujudkan kelayakan pekerjaan secara beriringan. Penelitian ini menggunakan metode Fuzzy C-Means Clustering untuk mengelompokkan 34 provinsi di Indonesia ke dalam klaster-klaster menurut karakteristik ketenagakerjaan. Analisis dilakukan dengan memperhatikan dua aspek, yaitu kesempatan kerja dan kelayakan pekerjaan. Penelitian ini berhasil mengklasifikasikan 34 provinsi ke dalam dua klaster. Klaster pertama beranggotakan provinsi-provinsi dengan tingkat kesempatan kerja yang rendah, namun kelayakan pekerjaannya sudah baik. Sedangkan klaster kedua memiliki karakteristik kesempatan kerja yang tinggi, namun belum diimbangi dengan kelayakan pekerjaan yang baik. Terhadap kedua klaster yang terbentuk, pemerintah diharapkan dapat memberikan perlakuan atau menerapkan kebijakan yang sesuai dengan karakteristik yang dimiliki.
In the Eye of the Storm: The Disrupted Career Paths of Young People in the Wake of COVID-19
Authors: Issehnane Sabina , Moulin Léonard
Published: March 2024

Using a survey representative of individuals who left the educational system in France at any level in 2017, we examine the impact of the COVID-19 pandemic on young people’s probability of being employed between the start of lockdown in March 2020 and July 2020. We find that the COVID-19 pandemic had a strong impact on youth employment. Our results show that young people’s probability of being employed decreased by as much as 3 % during the lockdown period relative to the pre-pandemic baseline. This impact is smaller than that observed in other countries, probably due to the significant measures implemented in France. Our heterogeneity analyses indicate that the impact of the COVID-19 pandemic on young people’s labor market integration varied with the type of employment contract, area of study, and, to a lesser extent, having a working-class parent, a foreign-born parent, or residing in a rural area.

Published: March 2024

Despite the several mismatches of methodological understanding between teachers and students in higher education, research methodologies in education are a relatively common pedagogical practice in most European advanced courses in education. However, only some studies have shown what pedagogical practices are mobilised by the teachers with their specific scientific conceptions. This article presents and discusses the results of an extensive research study conducted in Portugal with all the teachers involved in teaching research methodologies on master’s and doctoral programmes in education. The results show the personal and professional characteristics of the teachers involved in this teaching and the type of senses, decisions, and challenges experienced when teaching research methodologies. The study identifies and characterises the research culture generated by the different pedagogical practices in this scientific field. Based on the results, we argue that the teachers’ scientific conceptions and pedagogical practices may be developed by a “peer authorial construction of research understanding,” aiming to provide appropriate educational experiences to students in research methodologies courses in advanced studies in education.
Distributed self-healing control of single-phase grounding fault in neutral point non-effective grounding system
Authors: He Silin , Zhu Jiran , Zhang Di , Liu Shengpeng , Zhan Luxin , Chen Chun
Published: March 2024

In distribution networks, single-phase grounding occurrences in non-effectively grounded systems do not result in short-circuits, thus leading to low fault currents. Particularly in high-resistance grounding scenarios, fault currents become extremely low, increasing the risk of protection misjudgments. To enhance the speed and accuracy of self-healing during such faults, a distributed self-healing control method based on flexible grounding and zero-sequence current analysis for non-effectively grounded systems is proposed. This method employs peer-to-peer distributed self-healing and flexible grounding techniques to convert isolated or arc-suppressed neutral systems to low-resistance grounded systems. Additionally, a localization criterion unaffected by neutral grounding modes is introduced, utilizing deviations in zero-sequence current upstream and downstream of the fault as distinguishing characteristics. The proposed method is straightforward in principle and leverages existing terminal equipment for accurate and swift fault processing. Simulation results validate the method’s resilience to transition resistance and neutral grounding conditions, demonstrating its suitability for single-phase grounding fault localization across all system types. The research findings effectively ensure the accuracy and swiftness of self-healing during single-phase grounding faults in non-effectively grounded systems.
Optimal evaluation of symmetry-adapted n-correlations via recursive contraction of sparse symmetric tensors
Authors: Kaliuzhnyi Illia , Ortner Christoph
Published: March 2024

We present a comprehensive analysis of an algorithm for evaluating high-dimensional polynomials that are invariant (or equi-variant) under permutations and rotations. This task arises in the evaluation of linear models as well as equivariant neural network models of many-particle systems. The theoretical bottleneck is the contraction of a high-dimensional symmetric and sparse tensor with a specific sparsity pattern that is directly related to the symmetries imposed on the polynomial. The sparsity of this tensor makes it challenging to construct a highly efficient evaluation scheme. Bachmayr et al. (“Polynomial approximation of symmetric functions,” Math. Comp., vol. 93, pp. 811–839, 2024) and Lysogorskiy et al. (“Performant implementation of the atomic cluster expansion (pace): application to copper and silicon,” npj Comput. Mater., vol. 7, Art. no. 97, 2021) introduced a recursive evaluation strategy that relied on a number of heuristics, but performed well in tests. In the present work, we propose an explicit construction of such a recursive evaluation strategy and show that it is in fact optimal in the limit of infinite polynomial degree.

Published: March 2024

Indonesia is a significant producer of shallots, and the country frequently cultivates three distinct varieties: Bima, Trisula, and Sumenep. Each cultivar exhibits distinct characteristics, specifically when grown under suboptimal conditions. Several studies showed that insufficient watering intervals (WIs) can lead to drought stress, while excessive levels often lead to inundation. To investigate the effects of cultivar and WI on shallot growth and quality, this study employed a split-plot design with main plots and subplots with four repetitions. The main plots consisted of cultivars (Bima, Trisula, and Sumenep), while the subplots comprised WIs (once in 1 day, 2 days, and 3 days). The results showed that there was an effect of interaction between cultivars and WIs on growth (proline [126.15 mg 100 g−1]) and quality (quercetin [3.8739 mg g−1], rutin [0.2080 mg g−1], and kaempferol [1.209 mg g−1]). However, there was no effect on the number of tillers, shoot/root ratio, water content, number of tubers, tuber weight, and total flavonoid.

Drainage in sugarcane cultivation in high-rainfall areas is of paramount importance because it affects sugarcane plants from planting, maintenance, and production. Poor drainage can damage plants and reduce productivity. This study was conducted at Bone Sugarcane Plantation, which typically has high annual rainfall; thus, drainage is necessary. The existing drainage channel cannot drain all surface runoff quickly and causes problems to sugarcane plants. Therefore, a study was conducted with the aim of designing the shape and size of drainage channels that can drain surface runoff quickly, have a strong structure, allows for an effective use of cultivated land by reducing headland for tractor turning, and maintains appropriate soil moisture. The research began by determining the saturated hydraulic conductivity of the soil using the Falling Head method. Surface runoff discharge was calculated using rational equations to determine the dimensions of the drainage channel. Rainfall intensity was determined from Intensity Duration Frequency curve which was constructed using Manonobe method. The results showed that the saturated hydraulic conductivity of the soil was 3.54 × 10−3 cm/s which is suitable with surface drainage. Rainfall intensity is estimated to be 201.33 mm/hour. The shape and dimensions of the drainage channel are parabolic with the largest width and depth of 1.70 m and 0.90, respectively. This study provides a practical method to solve drainage problems in sugarcane fields that apply full mechanization. In addition, the practical analysis used in this study can be adapted to analyze the design of drainage channel for other plantations or regions with similar constrains.

Recent scholarship claims that group grievances due to political exclusion and discrimination drive civil wars. The grievance perspective suggests that socio-psychological factors allow groups to overcome collective action problems. We argue that the grievance perspective (over)focuses on the ends and not means, which are critical to explain how groups survive state sanction, allowing contention to escalate to civil war. We suggest that inclusive economic governance reduces investment in state-evading infrastructures for quotidian economic reasons, leading to the buildup of rebellion-specific capital. Physical and human infrastructures of state evasion form the logistical bases for survival against state sanction. Our analyses show that group-grievance-generating political factors are poorer predictors of civil war compared with economic freedoms measured as free-market friendly policies and the private ownership of economies, which should reduce economic rents accruing to state-evading shadow markets. Our results are robust to several alternative models, data, and estimating method. Theory that ignores the means explain the main causes of costly violence only partially, or mistake symptom for cause. Freedom and inclusiveness, which should reduce grievances, are intrinsically valuable, but they are hard to obtain when violence is waged successfully for more narrower ends.

To ensure safe human-robot cooperation, it is necessary not only to measure the force exerted during contact, but also to monitor an approaching action. This would allow avoiding any unintentional contact through evasive maneuvers and thus prevent possible injuries. In our contribution we analyze a localization system based on capacitance tomography where an approaching object constitutes an electrode of a multi-electrode capacitance. The system processes measured voltages made on the surface of a conductive layer. From this, the location of the capacitive coupling between the object and the layer can be reconstructed, and the position of the object can be estimated. The system’s performance is further analyzed using the Neyman–Pearson detector. To define the performance of the system, for object detection only, the influence of object distance, object area, and number of measurements used on the probability of detection is examined.

NiTi-based memory alloys are often used as intracorporeal implant materials because of their superelasticity and shape memory properties. However, over time, the release of nickel from the NiTi alloy into the body becomes unfavorable; therefore, studies should be conducted to reduce the negative impact of nickel leakage. In this study, the biocompatible selenium element was used to coat NiTi alloys with different thicknesses. The coating process was performed using the thermal evaporation technique. Scanning electron microscopy-Energy Dispersive X-ray Analysis measurements revealed that the surfaces of the samples were well covered. Also, the atomic force microscope device determined the surface roughness of the alloys. The roughness of the surface increased after the coating process. The Tafel test was accomplished to determine the biocompatibility of the coated and uncoated alloys in an artificial body fluid. The corrosion test reveals that Se-coated NiTi alloys have high corrosion resistance.

Emigrants who left the Municipality of Malaga in the 2017–2021 period went to multiple destinations, mostly municipalities located in the province of Malaga itself, more specifically in its metropolitan area. Average housing prices in these metropolitan municipalities are highly variable, and, in this context, it is reasonable to assume that there will be a relationship between the income levels of emigrants and their destination. Based on a special processing of the Municipal Register of Inhabitants of the Municipality of Malaga, we show how a relationship can effectively be found between the average household income (AHI) of the census tract of origin of the emigrants and the average price of housing in the destination municipality, both for the whole group of emigrants and for selected age groups – children and young adults. A relationship that points to an overrepresentation of municipalities with high housing prices in the sections with the highest income, and vice versa.

Corrosion is a natural process that occurs when refined metal is converted into a more stable form, such as oxide, hydroxide, or sulfide. Wear is the failure of a surface due to dynamic contact between two surfaces. In offshore operations and environments, corrosion and wear are major problems due to the presence of corrosive and abrasive elements. The coating is a common surface protection method that enhances corrosion resistance and prolongs lifespan. In this work, a Ni-Graphene nanocomposite coating was fabricated using the electrodeposition method. This work aimed to fabricate a Ni-GO nanocomposite coating on mild steel with different surface roughness, to characterize the physical, mechanical, and chemical properties of the coating, and to investigate its corrosion and wear rate. The fabrication process involved preparing substrates coated with Ni-GO nanocomposite through a 45-minute constant current electrodeposition process. The coated specimens were characterized using X-Ray Diffraction Machine (XRD), Scanning Electron Microscope (SEM), Alicona Infinite Focus, Vicker’s Hardness Test, Raman spectroscopy, and Adhesion test. The corrosion and wear rate of the coatings were investigated using a Slurry Erosion tester and Salt Water spray, respectively. The results showed that the Ni-Go nanocomposite coating on a smooth surface roughness substrate achieved the highest microhardness, wear resistance, and corrosion resistance, with values of 468.8 HV, 0.182% weight loss, and 0.03% weight gain, respectively. This indicates that the specimen coated with a smooth surface roughness substrate provided better coating performance than the rough and medium surface roughness substrates.
