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

Nanofibers are nanotechnologies with cross-sectional diameters ranging from tens to hundreds of nanometers. We explained the definition of nanofibers and their unique physicochemical characteristics. This study aimed to see the characterization of Polyvinyl pyrrolidone/Cellulose acetate/Aloe vera extract fiber. The fiber was made with a concentration of PVP/CA in 13% (w/w) and an Aloe vera extract in 10% (w/w) using the electrospinning method. The electrospinning technique involves an electrohydrodynamic process in which liquid polymer droplets are electrified to produce jets that elongate to produce fibers. Electrospinning is an easy, fast, and simple technique for producing fibers with sizes ranging from micrometers to nanometers. Process parameters used in this research, such as flow rate of 0,20 ml/hour, high voltage of 12 kV, and drum speed is 200 rpm with the distance to the needle tip of the collector is 75 cm. The result showed that fiber PVP/CA/AE morphology is bead free and homogeneous. The average diameter of PVP/CA/AE fibers was 1115 nm.These results indicate that the resulting fiber is in the form of nanofibers. A small fiber diameter will result in a broader surface area. The XRD result shows that the PVP/CA/AE fibers have a semi-crystal phase.

Abstract

This study aims to create a microcontroller-based hydrostatic pressure experiment tool in science education. The digital system makes the tools used more effective and time-efficient. The digital system used in this tool consists of a microcontroller, digital display (LCD), and the MS5637 Barometer sensor. This series of tools processes digital data into hydrostatic pressure, displayed on the LCD. The method used in this study is following Archimedes' principle. The independent variable in this study is the depth of the funnel thrust into the measuring cup, while the dependent variable is the hydrostatic pressure displayed on the LCD. The results showed that the hydrostatic pressure valuesobtained were close to theoretical calculations. Then, the r-squared result between Δh of water and hydrostatic pressure through experiments with a microcontroller (Arduino) is 0.9981. This value is good enough to show the proportion or percentage of hydrostatic pressure affected by Δh of water. Thus, experiments using this tool are quite effective in science learning.

Abstract

The most interesting problem to be discussed in electrical physics is one-way electric circuits. In this work, the researchers constructed an experimental setup for determining the time constant of DC resistors and capacitors using the open-source Arduino UNO hardware platform. Arduino UNO was a signal generator for data collection systems and a simple signal visualization instrument. Experiments were carried out using an analog oscilloscope combined with theoretical calculations. The results show that, on a spreadsheet, the data processing and fitting of the curves for the six Resistor and Capacitor test sets yielded values determined by the component tolerances. The researchers believe that the design of this equipment and software demonstrates the recommended suitability, making it flexible for use in teaching and learning in laboratory contexts.

Abstract

The  theory, as a modification of the general relativity theory, is frequently employed as an alternative theory of gravity and offers a promising avenue for addressing the challenges of formulating a quantum gravity theory. In this study, by applying the separation method of time, radial and angular variables, we derived the general solution of the Klein-Gordon equation in a curved space-time using modified Schwarzschild metric. We modified Ricci scalar  form in Einstein’s action principle as a general function of Ricci scalar  and formulated the general Schwarzschild metric. The solution of the time function was analytically obtained in exponential form, and the solution of the angular function in terms of Legendre polynomial depends on azimuthal and magnetic quantum numbers. The radial function in terms of a non-linear second-order differential equation was solved by a numerical method using Python. The solutions described the gravitational effect for a light particle on the area gravitationally has a strong interaction, represented by a spherically symmetric metric. For small  (in Schwarzschild radius), the results analytically show that the gravitational effect in this region is massive. It follows that even light would be drawn into a black hole and unable to escape. For further research, it is expected to extend the Klein-Gordon equation in relativistic quantum mechanics to modified general relativity theory. This theory offers a different way of looking at the effects of gravity in quantum field theory.

Abstract

This study aims to examine the effect of altitude on the acceleration of gravity with the help of smartphone acoustic sensors. The altitude varies from the interval 100-1061 MASL (Mean Above Sea Level), located around the Special Region of Yogyakarta. An iron ball is dropped from a certain height, and the time it falls is observed using an acoustic sensor in Phypox, and the results are used to determine the acceleration value due to gravity (g) through the equation g = 2h/t2. Fitting data from measurements of the four altitude variations are shown in the polynomial equation y = 0.000003x2 – 0.0035x +10.718 m/s2 with a regression number R2 = 1,000. This equation shows that the acceleration value due to gravity will decrease quadratically with each increase in the altitude per meter above sea level.

Abstract

One factor that significantly affects rainfall in Indonesia, especially in Palembang City, is the El-Nino Southern Oscillation (ENSO). This study aims to determine how big the correlation is and when the highest correlation occurs between the Nino 3.4 Index and rainfall during the 2001-2020 period. The stages of analysis carried out to carry out this study are as follows: 1) downloading daily rainfall data for 20 years, 2) processing the raw data to make it homogeneous, and 3) correlation analysis to find out when the highest correlation occurs between rainfall and the Nino 3.4 Index. The results show that the highest correlation occurs in September at -0.524, August at -0.481, and October at -0.439. The influence of the Nino 3.4 Index produces a negative relationship. If the Nino 3.4 Index increases, it will affect the maximum temperature at the sea surface so that rainfall will decrease and cause drought. The results obtained can also be used as a prediction or forecast of the inflow of rainfall and the length of the rainy season.
