Authors: Ardiansyah Angga , Mulyati* Yayuk , Wicaksono Azizul Ghofar Candra
Published: June 2024

Critical thinking skills (CTS) are essential in the 4.0 era. However, the attempts to enhance these skills during learning are still suboptimal, particularly in science education at the junior high school. Gender is believed as one affecting factor on students critical thinking. The research investigated the effects of problem based learning (PBL) student worksheets on students critical thinking from the perspective of gender differences. This quasy experimental research applied pretest-posttest nonequivalent multiple group design. The samples were chosen through purposive sampling, resulting in one male class having 24 students and one female class having 24 students. The research instruments included a lesson plan, a PBL-based student worksheet, and pretest-posttest questions that had been validated. Data analysis uses statistical tests in the form of paired and independent sample t-tests, and N-gain. The analysis indicated that using PBL-based student worksheets increases CTS more effectively in female students than in male students. These are proven by paired and independent sample t-tests showing a significant difference (Sig. 2-tailed = 0.000 0.050) with N-gain signifies a moderate increase of 0.6 for male students and a high increase of 0.7 for female students. These findings may serve as recommendations to enhance students critical thinking and as a reference for gender-segregated schools in designing learning programs that optimize the role of each gender

Published: June 2024

This research aims to determine the effect of kits renewable energy projects by implementing a project-based learning model on students' lower order thinking skills (LOTS) and higher order thinking skills (HOTS). The research method used was quasi-experimental with a nonequivalent posttest only control group design. The population in this study was 198 students. Samples were taken randomly from a population that had passed the normality test and homogeneity test. This research uses a cognitive learning outcomes test instrument in the form of multiple choices. The research results show that there is no significant difference in cognitive learning outcomes in the LOTS category between students in classes that apply project-based learning on renewable energy material and classes that apply conventional learning on renewable energy material, sig. 0.127 ≥ 0.05, using the Mann Whitney test. Meanwhile, the results of hypothesis testing for cognitive learning outcomes in the HOTS category using the independent sample t-test obtained a sig (2-tailed) value of 0.000 ≤ 0.05, which means there is a significant difference in students' cognitive learning outcomes. between classes that apply project-based learning to renewable energy material and classes that apply conventional learning to renewable energy material. These results indicate that project-based learning can produce student learning in the HOTS category, but has no effect on increasing students' cognitive abilities

Published: June 2024

One aspect of process science skills that learners need to have is the ability to interpret. The ability to interpret graphs in students is currently considered difficult and still belongs to the very low category. This study aims to analyze the relationship between mathematical understanding and the learning styles of students in terms of their ability to interpret graphs. This type of research is descriptive-quantitative. The research sample consisted of class XI students at SMA Negeri 4 Takengon, which amounted to 67 students. The research data was collected using learning style-type questionnaires, multiple-choice questions on linear program material, and reaction rate material. The ability to interpret the graphs of students at SMA Negeri 4 Takengon is on the "medium" criterion, while the students' mathematical understanding is on the "very high" criterion. Students with visual learning style types are more dominant and have an average score of mathematical understanding and the ability to interpret graphs higher than students with auditorial and kinesthetic learning styles. The result of the correlation coefficient r = 0.912 shows a significant positive relationship between mathematical understanding and the ability to interpret graphs with a "high" and unidirectional interpretation
MEASURING THE AESTHETICS OF PHOTOGRAPHIC COMPOSITION USING CARTESIAN COORDINATE APPROACH TO PROVE VISUAL BALANCE
Authors: Prasetyo Martinus Eko , Resmika Ika
Published: June 2024

Photography is used for creative and reflective purposes, much like in fine art photography. The main goal of photographic aesthetics is to produce works that are not only technically sound but also have high artistic value. The research method used is qualitative descriptive. This study aims to measure the aesthetics of composition in photography with a focus on proving visual balance. Composition aesthetics are studied through the analysis of elements such as the golden ratio, symmetry, and tonal distribution. The research method involves collecting and analyzing data from sample photos with various compositions. The results show that visual balance can be measured using mathematical approaches and aesthetic principles, which influence the perception of beauty in a photo. The implications of this research are to strengthen understanding of how visual composition affects aesthetic judgment in photography. This research produces measures of aesthetic visual balance composition that will elevate case studies of six photographs from six professional photographers of different genres, whose works are internationally recognized, namely the works of photographers Natalie Dybisz, Lee Jeffries, Jimmy Nelson, Ansel Adams, Dorothea Lange, and Robert Capa, which will be measured visually using a three-to-two basic framing grid approach.

Im Bann der Konjunktur - Entstehung und Institutionalisierung der Konjunkturbeobachtung in der Schweiz, 1932–1980
Authors: Ronca Marion
Published: June 2024

Konjunkturdiagnosen und -prognosen erwecken den Eindruck, dass sich der Zustand und die künftige Entwicklung einer Volkswirtschaft objektiv bestimmen lassen. Tatsächlich aber werden Wirtschaftskrisen kaum je vorausgesehen und eine Einigkeit über die Wechsellagen der Wirtschaft, ihre Ursachen und ihren Verlauf herrscht – bestenfalls – nachträglich. Warum also existieren Konjunkturprognosen? Die Geschichte der Schweizer Konjunkturbeobachtung zeigt, dass die Bestimmung der Wirtschaftslage nicht primär den Zweck verfolgte, die Zukunft vorauszusagen. Vielmehr strebte sie eine Objektivierung der Konjunkturmeinung an. Im Wesentlichen bildete die Konjunkturbeobachtung aber eine Streitpraxis, bei welcher Wissenschaft, Politik und der Staat um die Deutungshoheit über die wirtschaftlichen Verhältnisse und ihre Handhabe rangen.

Published: June 2024

The sudden shift to distance and hybrid learning due to the COVID-19 pandemic created a need to identify out-of-school learning settings and practices that reflect the vision of inquiry in science education. The meaningful adaptation of science materials in a distance learning environment combined with face-toface learning can promote and enhance development of science concepts as well as science practices. We present the teaching material as a three-level gradually developing design that provides opportunities for pupils to engage in home (out-of-school – level 1), school (classroom, school lab – level 2) and specialized (specialized lab, university – level 3) settings. A set of several scientific research questions is introduced. They have increased complexity and precision (three levels), are relevant and authentic for pupils (aged 11 – 17) with potential to develop all aspects of scientific literacy.

Button mushrooms and asparagus have a very short shelf life after harvesting and are sensitive to mechanical  damage, browning, moisture loss and chlorophyll  degradation. An edible coating based on rice bran protein (RBP) was tested in order to determine the shelf-life  extension period of mushroom and asparagus. Weight loss, color browning, ascorbic acid, total chlorophyllm pH, total titrable acidiity, polyphenol oxidase activity and peroxidase activity of mushrooms and asparagus were studied. Also, microbiological analysis of the coated samples was studied. The results revealed that, weight loss and firmness of samples decreased with of using RBP coating compared to the control samples. Also, RBP coating maintain the pH values for samples during storage compared to control. Ascorbic acid decreased during storage for both coated and uncoated while, the uncoated samples decreased more. Also, RBP coating was effective to maintain of the color compared to control. Finally, the study showed also that RBP coating with bacteria, molds and yeasts of mushroom and asparagus samples compared to control.

The interaction between a pin-plate and plasma are representing an interest subject in plasma technology and applications. In this research, the influence of added NaCl to distilled water on the discharge characteristics that formed in the gap between pin-water surfaces was investigated in more details. Their electrical and optical characteristics serve as identifiers. It's found that all optical emissions intensity peaks as a results that detected are decreased with increasing of NaCl concentrations (300,400, and 500 mg). As well as, the emission intensity of neutral emission peaks are much higher than that of the ionic emission peaks. The addition of NaCl changes the liquid accessibility, which alters the kinetics of the discharge that forms in the pin-water surface gap. Also, its observed that the NaCl concentrations affected on the I-V characteristics. The data detected that the plasma frequency ((377.1176 - 279.1951)*1011 rad/sec), electron number density ((4.4519 – 2.4401)*1017 cm-3) and electron temperature (2.1537 – 1.663 eV) decreased with increases of NaCl concentrations except the Debye length ((1.6342 – 1.93989)*10-6 cm) shown a different behavior with increase of NaCl concentrations.

OBJECTIVE: To evaluate the effect of a workplace injury prevention and wellness program compared to no intervention (control) on musicians’ playing-related musculoskeletal pain intensity. The hypothesis was that musicians who completed the program would have a greater reduction in pain intensity than the control group.

DESIGN: Pragmatic parallel randomized controlled trial.

METHODS: Sixty-five orchestra musicians were recruited and completed patient-reported outcome measures (primary outcome: pain intensity over 11 months, using the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians; range: 0-40; lower is better) at baseline, 14 weeks (T1), and 11 months (T2). Following baseline assessment, participants were randomly assigned to the intervention (n = 33) or control (n = 32) groups, stratified by instrument and pain prevalence. The intervention group received a 14-week injury prevention and wellness program including education and exercise; the control group received no intervention.

RESULTS: Pain intensity means (standard deviation) were 7.8 (6.2), 8.0 (7.5), and 8.6 (5.7) in the control group, and 9.0 (6.6), 5.0 (4.2), and 6.7 (6.6) in the intervention group at T0, T1, and T2, respectively. Using intention-to-treat analyses (3 dropouts, n = 65 analyzed), between-group differences in pain intensity (95% confidence interval) were T1-T0: −4.2 (−7.5, −0.9); T2-T0: −3.7 (−7.1, −0.3), type III (overall) P = .03, favoring the intervention group. No adverse events were reported.

CONCLUSION: A workplace injury prevention and wellness program may have a clinically meaningful effect on reducing orchestra musicians’ pain intensity. J Orthop Sports Phys Ther 2024;54(9):584-593. Epub 11 June 2024. doi:10.2519/jospt.2024.12277

Floods are the most destructive natural disaster. Due to predicted climate change, hydrological risks will increase in the North and the Arctic, which makes residents of these regions vulnerable. The population of flood-prone areas is aware of the potential flooding, but is not always prepared for it, just like the management system. The article presents the results of a survey conducted in eight settlements of Yakutia previously affected by floods, half of which are located in the Arctic zone of the Russian Federation. The researchers reveal that the perception of hydrological risks by the population is influenced by the amount of damage suffered during the last flood, and the assessment of the effectiveness of various levels of management during the flood and at the recovery stage is influenced by the amount and form of its compensation.

Ice cellars are a traditional way of long-term storage of meat and fish near the places of their commercial production in the Arctic during warm season. Due to the degradation of permafrost, these structures are in a state of disrepair everywhere. Using the example of the Chukchi national village of Lorino, where traditional hunting of sea animals is preserved, we have considered options for solving the problem of preserving the caught meat. Economic assessments show that the use of a permafrost storage facility is reasonable for storing more than 100 tons of products; for smaller volumes, it makes sense to switch to refrigeration containers powered by renewable energy sources. Selling excess energy and heat from a chiller can generate significant revenue. Especially if this energy is used to create the maximum benefit under the given conditions, e.g. in vegetable growing.

The paper reviews the approach of assessing mechanisms and factors determining the formation of a gas condensate spill from a shallow underwater emergency discharge at a gas condensate field. The researcher determine spatial and temporal formation scales of an intense evaporation zone for the characteristic flow rates of underwater wells, necessary for assessing the area of increased gas contamination in which it is impossible to carry out emergency recovery measures. They establish that the radial flow in the area where the gas-liquid plume exits the sea surface determines the size of the intense evaporation area; at low values of wind speed and currents, it depends on the well flow rate, gas factor and fractional composition of the oil product. The researchers have carried out calculations using the SPILLMOD model and the evolution model of a characteristic Lagrangian element in the spilling region.
