The research objectives are to determine the effects of the Brain-based Learning (BBL) approach on students' higher-order thinking skills and student motivation to learn physics. This research used the quasi-experimental pretest-posttest design. The sample of this research consisted of two tenth-grade science classes chosen by simple random sampling technique. This research population was all tenth-grade students of a senior high school in Yogyakarta. The data were obtained by test and non-test techniques. The result shows that BBL approach affects on the students' higher-order thinking skills (sig. 2-tailed = 0,003 <α = 0.05). Further, it also improves students' higher-order thinking skills represented by the N-Gain value (experimental class N-Gain = 0.40 > control class N-Gain = 0.21). On the other hand, not only on student's higher-order thinking skills, BBL approach bring the significant effect on students’ motivation in learning physics (sig. 2-tailed = 0,000 <α = 0.05) as well as could improve it (experimental class N-Gain = 0.55 > control class N-Gain = 0.04). It means that the BBL approach could improve higher-order thinking skills and students' motivation more effectively than the traditional approach

Visualization of physical phenomena through modeling and virtual experiment help students to understand the physics concepts. The concept of momentum is quite challenging to explain without the help of virtual experiments.This study aimed to analyze students' independent learning after conducting the learning process on the concept of momentum using Tracker software as a virtual experimental model. This study was quasi-experimentalwith the purposive sampling technique to determine the control class and the experimentalclass. There were 42 students involved in this research. The control class was treated by actual experiments on learning, while the experimental class used the Tracker software as a virtual experiment model. The instrument used was questionnaires given at the end of learningto measurestudents’ learning independence. The data were analyzed by using the descriptive statistics method. Learning independence in the control class obtained 51.31% in the medium category, and the experimental class obtained 60.95% in the medium category. Although the average achievement was not significantly different, the aspects of responsibility, motivation, and self-evaluation of the experimental classwere better than that of the control class.

The influence of storage room conditions can cause the quality of post-harvest fruit to decline, so monitoring is necessary. Monitoring is carried out using a data acquisition system designed to measure the temperature, oxygen, and carbon dioxide in the refrigerator storage room automatically. System design is divided into two stages, namely hardware design and software design. The hardware is composed of a sensor unit, a data processing unit (Arduino Mega 2560), and a display unit. On the other hand, the software uses the Arduino IDE. The test results of temperature (DS18B20), oxygen (Figaro KE-25), and carbon dioxide (MH-Z14a) from the system obtained an accuracy value of 98.29% with an error of 1.71%; 98.57% with an error of 1.43%, and 94.58% with an error of 5.42%. The device can display real-time measurement data output to 20x4 LCD with IIC and save the data on a micro-SD card.

Theory about Newton's Law is considered difficult for students. Many students cannot solve Newton's Law’s problems caused they cannot understand the concept. Concept understanding requires complex learning by increasing students’ motivation. This study aimed to explore the relationship between students’ motivation through scientific argumentation skills and students’ learning outcomes on Newton's laws. This research was a non-experimental mixed-method study with an embedded-correlational research design. The subjects of this study were 32 students of Senior High School (SMA) Laboratory UM Malang (State University of Malang). The sampling technique used in the study was purposive sampling, specifically homogeneity sampling. The research instrument consisted of open-ended questions, semi-structured interviews, questionnaires, and document identification. The data analysis technique used was a partial correlation test for quantitative data and descriptive analysis through coding for qualitative data. The results showed that the quality of students' scientific arguments was most dominant at Level 2. The arguments consisted of claims supported by data. However, the students sometimes claimed incorrect understanding of Newton's Laws I and II. The results of the partial correlation test between motivation and scientific argumentation and student cognitive learning outcomes did not show any correlation. However, there was a positive effect.

During the production of batik cual, thick-colored wastewater is produced. Unfortunately, the wastewater could damage the environment if it is disposed of without specific processing. The Fenton method is an advanced oxidation process (AOPs) that can degrade organic dyes found in liquid waste. In this research, the researchers studied the Fenton mechanism's application to the batik cual wastewater treatment. The Fenton's reagent used was H2O2 with FeSO4.7H2O. Some of the experimental wastewater treatment parameters were the values of biological oxygen demand (BOD), chemical oxygen demand (COD), the degradation efficiency of difficult to decompose organic materials, and the color degradation efficiency in batik cual wastewater. The results show that the Fenton mechanism’s efficiency of removing color from batik cual wastewater is up to 97.8%, COD and BOD removal efficiencies are 76.3% and 75.2%, and the degradation efficiency of difficult to decompose organic matter is 76.8%. Also, the researchers found that the higher amounts of FeSO4.7H2O increase the removal parameters effectiveness. Therefore, the Fenton mechanism can effectively improve the quality of wastewater in batik cual production.

The researchers present a simple experimental activity to measure the sound intensity level using an Android-based smartphone to prove the inverse square law and analyze the dependence of the sound intensity to the sound source frequency. The type of this study was quantitative research by conducting level of intensity experiment using a pair of smartphones with one smartphone functioning as the sound source using a tone generator free application (app) and the other smartphone functioning as the detector installed with Physics Toolbox sound meter application to measure the arriving sound intensity level. The smartphone functioning as the sound source was placed at a certain place labeled as the origin point (0.0), while the other smartphone as the detector was placed at various distances on the x-axis. In this study, the frequencies of the tone generator used were 500 Hz, 1000 Hz, and 2000 Hz. Then, the sound intensity level versus distance was analyzed to determine the compatibility between the experimental results using a smartphone and the prevailing theory, namely the inverse square model. The sound intensity level detected by the smartphone from 2,000 Hz resulted in the graph with smaller slope after passing 0.3 meters. The results follow the theorem of which the sound intensity level at the detector depends on the distance between the source and the detector based on the inverse square law. When the frequency of a source was changed (500 Hz, 1000 Hz and 2000), the sound intensity also changed. Higher frequency leads to a larger sound intensity. The experiment can thus be used to assist high school students and physics undergraduates in understanding the inverse square law of sound or to study environmental noise with a simple and low-cost experiment.

This research aimed to understand the critical thinking ability improvement and preparedness assisted by Android-based media to understand landslides through physics learning and understand the effectiveness of the media. This research provides knowledge about disaster preparedness through physics learning in landslide-prone schools using Android media. This research used quasi-experimental with Control Group Design. The research subjects included tenth-grade students in class X (30 people) at SMA N 1 Kokap. The samples were selected using the lottery method and saturated sampling technique to determine the control and experiment groups (quasi-experimental with Control Group Design). The pretest and posttest were in the form of essay questions. The analysis data used independent sample T-test and effect size. The results show that the average critical thinking ability of the experimental class increased from 18.13 to 65.00, and the average preparedness increased from 68.75 to 81.88. The results of the independent sample t-test show the value of Sig. (2-tailed) on critical thinking ability was 0.000 and preparedness was 0.027 (Sig. (2-tailed) <0.05). Thus, it can be concluded that there are significant differences in critical thinking ability and disaster preparedness in the experimental class and the control class. The effect size of using an Android-based understanding of landslide natural disasters on students' critical thinking ability and preparedness is 2.0 with high effectiveness. Media landslides and landslides through Android-based physics learning can improve students’ critical thinking ability and disaster preparedness.
