Abstract

A high failure rate in physics subjects is caused by students' inability to understand the material. The physics learning process certainly requires an appropriate learning approach. The learning analytics approach is one of the innovations in learning. It allows students to analyze problems. Therefore, this research aimed to determine the learning analytics approach's effect on improving students' multiple representation skills. This research is experimental. The validation of the lesson plan obtained excellent results based on two material experts and four practitioners. Furthermore, the empirical test was carried out on 504 students. The research design was the pretest-posttest control group design. The control and experimental groups were determined using cluster random sampling. The findings of this research include (1) the normality test results that are higher than 0.05, which means that the research data was normally distributed. (2) The homogeneity test results were higher than 0.05, which indicated that the data was homogeneous. (3) The paired sample T-test obtained a value lower than 0.05, which means that there was an influence of the multiple representation approach. (4) The N-gain value in the experimental class was higher than the control class. Lastly, (5) only 47.2% of students used graphical and mathematical representation skills. Based on these findings, the effect of the learning analytics approach on students' multiple representation skills was fairly good with moderate criteria. For further research, learning products or models can be developed to improve multiple representation skills focused on a combination of graphics and mathematics.

Abstract

In this study, the researchers focused on testing experimental media from Yeti Rusmiati to measure the dielectric constant of capacitors, with variations in thickness, surface area, material, and density. The experimental results show that the thicker the dielectric material, the smaller the capacitance value. This applies to all materials tested, namely mica, silicon, and duplex paper, with errors from largest to smallest being 24.97% duplex, 7.27% mica, and 0% silicon. Measuring the capacitance of parallel plate capacitors with variations in plate area from GRC gypsum, silicon rubber, and mica, it was found that the error from largest to smallest is mica 11.56%. In comparison, silicon rubber and GRC gypsum have an error of 0%. Measurement of capacitance by varying the dielectric material shows that the capacitance value of the capacitor is proportional to the dielectric constant of the material. Among all the 12 materials tested, the highest dielectric constant is banana leaves with a value of ? = 12.6 and the smallest flannel with a value of ? = 1.02. In contrast, the variation in density shows that the greater the density, the greater the dielectric constant, from the largest to the smallest, the variation in density of leaves steamed with fire, fresh leaves 1 x 24 hours, and dry leaves heated with the sun, respectively 67.51;22.96; 16.57. It can be concluded that Yeti Rusmiati's media can be used in measuring dielectric constant with variations in thickness, area, density, and dielectric material in learning capacitors.

Abstract

LaFeO3 (LFO) is commonly used as a material for gas sensor applications. However, the LFO material in ethanol gas sensor applications can still improve sensitivity and selectivity parameters. Gadolinium (Gd) doping is widely used in gas sensor applications to increase the sensitivity of gas sensors. In addition, reduced graphene oxide (rGO) materials are commonly used in gas sensor applications to increase gas sensors' selectivity, sensitivity, and working temperature. This study analyzed the effect of Gd doping (LGFO) and the addition of an rGO single layer on LFO material (LGFO@rGO) on sensitivity and selectivity based on the adsorption energy of the system with ethanol gas molecules. Density Functional Theory studies were conducted to yield insight into the LGFO or LGFO@rGO – ethanol gas interactions and the sensitivity and selectivity improvement by changing adsorption energy. Based on the analysis, the presence of Gd doping and single-layer rGO could increase the adsorption energy. The addition of the rGO layer showed an escalation of the adsorption energy of about 9.45%, 2.49 eV in the LGFO to -2.75 eV LGFO@rGO. This improved adsorption capacity translates to a higher sensitivity for detecting lower concentrations of ethanol gas. This result shows the potential of LGFO and LGFO@rGO as ethanol gas sensor materials.

Abstract

The Peter Half Slope method is valuable for estimating rock depths using total magnetic field anomaly data. It relies on graphical analysis and practical rules to gauge the depths of magnetic sources. This method finds significant utility in magnetic interpretation, measuring half the maximum slope distance on magnetic anomaly curves. The primary objective of this research is to determine anomaly depths within Medan City by applying the Peter Half Slope method. The study employs total magnetic field anomaly data from the Medan city area, a part of the Northern Sumatra Basin. The research methodology includes data preparation, reduction to the pole transformation, profile creation, maximum slope computation, half-slope determination, and identifying tangent points on both minimum and maximum curves. The difference between these tangent points is then calculated to derive the depth of the bedrock. Based on the depth calculations using criteria for very thin, intermediate thickness, and very thick bodies, depths of 401, 301, and 240 meters were obtained, resulting in an average depth of 314 meters. This method plays a pivotal role in characterizing subsurface rock structures and is essential for geophysical analysis and magnetic data interpretation.

Abstract

Grids are additional accessory in radiography that absorb scatter radiation hoping to reduce blurriness on the image.  Various type of grids is available in the market so the effect of those on image quality needs to be evaluated. The purpose of this study is to compare the quality of abdominal radiography images using three variations of grids (moving and stationary grid) and without using a grid in order to see the best type or grids to produce the greatest image quality. Abdominal radiography exposure factors were used to expose two phantoms. Pro-Fluo 150 phantom was used as the object to measure image quality such as Signal to Noise Ratio (SNR), Contrast to Noise Ratio (CNR), and spatial resolution. A survey of five radiologists was also performed to evaluate the contrast and the visibility of objects’ boundaries in Anthropomorphic phantom images. The result of this study showed that the usage of various grids gave different values of SNR, CNR, and spatial resolution. The exposure factor of 70-75 kV in each mAs have the highest SNR value (52,64-78,31). Images obtained without a grid and exposure factor of 80-85 kV in each mAs have the highest SNR value (160,65-800,48). Images obtained from using moving grid also have the highest CNR and spatial resolution, with score of 3.72 – 7.62 and 3.7 lp/mm. The results of radiologists’ survey showed that the average score for moving grid’s images was 29.8 of 30 with a percentage of 99.33%. Therefore, it that can concluded that images obtained with moving grid have the best quality that can provides contrast and shows the boundaries between organs clearly in abdominal radiography. Based on this research, it’s recommended to use moving grid for abdominal radiography examinations.

Abstract

Environmental Physics concepts are very likely to be explored to facilitate the cultivation of spiritual attitudes because they are closely related to phenomena in everyday life. Visual media can help visualize environmental phenomena so that they are easier to understand. This study aims to instill spiritual values through the concept of Environmental Physics as an alternative learning that focuses on the affective domain with the help of visual media. This study involved 15 science education postgraduate students. This research used a Pre-experimental design with a Shoot Case Study. The research design includes pre-experiment, experiment, and analysis of experimental data results. In the pre-experiment stage, the concept of environmental physics and spiritual attitudes were analyzed, learning tools were prepared, and questionnaire instruments for student perceptions related to the cultivation of spiritual values were prepared. At the experimental stage, the implementation of Environmental Physics learning integrated with spiritual values was carried out. In the post-experiment stage, data analysis and interpretation were carried out to answer research problems. Based on the results of data analysis, it is known that 92.15% of respondents strongly agree that learning environmental physics can instill awareness of the nature of God. Based on the results of the open-ended questionnaire, it is known that students can explain the content of spiritual values in various phenomena in the environment. In addition, students stated that visual media can facilitate the activity of instilling awareness that God is omnipotent over all the universe. Thus it can be concluded that environmental physics learning activities can instil spiritual attitudes through environmental physics content assisted by visual media. Science content, especially environmental physics, is very relevant in instilling spiritual values
