Abstract:
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.

Abstract:
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.

Abstract:
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

Abstract:
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.

Abstract:
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.

Abstract:
Misconceptions frequently occur in various physics concepts, including momentum and impulse. Misconceptions in students must be addressed since they can hinder the learning process. This study aimed at investigating students' misconceptions on momentum and impulse material after implementing Interactive Conceptual Instruction (ICI) with computer simulations. The method employed in this study was a quasi-experimental design with One Group Pretest-Posttest Design. This research was conducted on 30 students of the tenth grade determined by the purposive sampling technique. Fifteen four-tier test items were used as the research instrument. The N-gain analysis was performed to know the reduction of misconceptions. The results showed that the N-gain value obtained was 0.46 with moderate interpretation, meaning that Interactive Conceptual Instruction (ICI) aided with computer simulations could reduce student misconceptions. The results also indicated that the misconception after treatment was smaller than before treatment. This phenomenon can be seen from the reduction of misconceptions by 11.6% after implementing Interactive Conceptual Instruction (ICI) with computer simulations. Therefore, it can be concluded that the Interactive Conceptual Instruction (ICI) with computer simulations can facilitate students in the learning process so that misconceptions can be reduced.

Abstract:
The present study focuses on the approach of the concept of light by primary school students. The study explores how a teaching procedure founded on using the metaphor that light travels as a wave reflects on the concept of light as a distinct natural entity. The experimental method was used for the research. One hundred and fifty-two children aged between 7 to 8 years old (average age 7.59) from 9 different primary school classes in Colorado, USA, participated in the research. An experimental and control group was delineated. Following a socio-cognitive perspective, the experimental group took part in a teaching procedure based on using the metaphor that light travels as a wave. Following an empiricist perspective, the control group took part in a teaching procedure based on a description of the phenomenon without using a metaphor. Data had been collected through pre and post-test, which results were analyzed using the Mann-Whitney test. The quantitative analysis showed an essential difference between the two groups. The experimental group pupils achieve higher learning outcomes as they better understand light as a distinct entity. It is argued that using a metaphor allows children to make connections with their everyday life, wonder about, and conceptualize light in a more efficient and meaningful way. The study informs everyday educational practice by providing a quality improvement element for learning and teaching about the primary classroom light

Abstract:
The study's purpose was to describe students' learning difficulties in physics, the causes of students' learning difficulties in physics, and the remediation to solve students' difficulties. This research was exploratory research with qualitative and quantitative approaches. The populations of this study were eleventh-grade students of SMAN 6 Palu. The respondents were chosen based on the lowest posttest results. The research instruments were OSRT treatment, pretest, posttest, and diagnostic test. The data were analyzed by comparing the pretest results, the posttest, and the gain score to determine the improvement after the remediation. Respondent A obtained 0.71 within the high category, respondent B obtained 0.69 within the high category, respondent C obtained 0.85 within the high category, respondent D obtained 0.84 within the high category, and respondent E obtained 0.46 within the moderate category. It can be concluded that internal and external factors caused difficulties. The internal factors were students' weak basic knowledge and weak material prerequisites, while the external factors were the teacher's learning methods that did not attract students' attention. The OSRT can overcome the difficulty in understanding Newton's law's concept to improve their ability to understand physics concepts.

Abstract:
Heat rate and heat capacity are widely used to determine the thermal characteristics, especially for wastewater treatment using electro coagulant. This study aimed to determine the value of heat rate and heat capacity of the waste solution in the textile industry, especially in the dyeing waste, by using a microcontroller device. The method for measuring the specific heat capacity and the textile waste solution's heat rate is based on the principle of the first law of Thermodynamics. Temperature measurements were carried out using a digital temperature sensor type DS18B20. In this research, the heat rate and specific heat of the dyeing solution and mineral water used in the textile industry have been studied. This study uses five types of dyeing waste solution as test solutions, namely green waste solution, orange waste solution, blue waste solution, brown waste solution, and mineral water. This experiment's principle is applying Joule's law by using electrical properties with a microcontroller device used to obtain the rise of temperature data each time in real-time every 2 seconds. Based on this research, it can be concluded that the instrument can be used to measure the heat rate and heat capacity of a textile waste solution. Based on this research, we also found that the specific heat of hard water (Hard water is a kind of water with high mineral content, while soft water is water with low mineral content. Apart from calcium and magnesium ions, the cause of hardness can also be other metal ions as well as bicarbonate and sulfate salts) (4.19 ± 0.77) J/ gram ℃ and the specific heat of the four types of waste solution ranged from (3.20 ± 0.72) J/gram ℃ to (6.83 ± 1.71) J/gram ℃ and also it was found that the heat rate of hard water is 0,0471 ℃/s and the heat rate of the four types of waste solution is range from 0,0289 ℃/s to 0,0617 ℃/s.

Abstract:
The purposes of this research were to estimate the crystallite size, density, and chemical composition of the ingot Ti: Al2O3 crystal grown by the Czochralski method. The crystallite size and composition of Ti: Al2O3 crystals had been determined using x-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDXS). Based on the Archimedes principle, the density of the crystals had been determined. The XRD patterns showed a single central peak with high intensity for all samples. It indicated that all samples had a single crystal. The average value of the samples' crystallite size was in the range of 20.798 nm to 34.294 nm. The ingot crystal density and Ti composition increased from the top to the bottom part because the solid solution was distributed unevenly during the growth process.

Abstract:
Linear air track is often used in physics learning for linear motion experiments because it can reduce friction between objects with trajectories. However, the use of air tracks for motion experiments in schools often does not care about aspects of air drag, so the purpose of this study is to calculate the air friction contained in the air track and as an offer of enrichment experiments at senior high school. The research method used is an experimental method that uses a set of air track experimental devices consisting of trajectors, carts, blower, and time counters with light sensors. Cart objects with a mass of 120.02 gram is given the initial velocity variation 12.272 cm/s, 16.286 cm/s and 24.599 cm/s. Then the time recorded when the cart crosses the distance of 10 cm to 110 cm at intervals of 10 cm. This experiment is conducted in the Integrated Science Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang. The second Newton law has been derived to obtain a special exponential function, so the relation between distance and time is obtained. The non-linear relation between distance and time shows the effect of air drag. Then, fitting the graph of the distance and time relation so that the air drag constants obtained are (10.6 ± 0.1) gram/s, (10.6 ± 0.2) gram/s, and (11.1 ± 0.2) gram/s. The results of the air drag constants obtained can be additional data as a factor affecting experiments using linear air track and can be enrichment experiments at senior high school laboratory.

Abstract:
The purposes of this research were to investigate the synthesized Nylon-6 nanofibers using electrospinning technique and their characteristics. The method used in this study was an experimental method with a quantitative approach. Nylon-6 nanofibers have been produced using the electrospinning method. This fiber was made with different concentrations, i.e. 20% w/w (FN1), 25% w/w (FN2), and 30% w/w (FN3). The SEM results show that the morphology of all nylon-6 nanofibers) forms perfect fibers without bead fiber. Increasing fiber concentration from 20% w/w to 30% w/w results in bigger morphology and fiber diameter. The dimensions of the FN1, FN2, and FN3 fibers are 1890 nm, 2350 nm, and 2420 nm, respectively. The results of FTIR analysis showed that the increase in the concentration of nylon-6 (b) and the electrospinning process caused a peak shift in the amide II group (CH2 bond), the carbonyl group and the CH2 stretching of the amide III group from small wave numbers to larger ones. The results of XRD characterization showed that the electrospinning process affected the changes in the XRD pattern of nylon-6 nanofiber (FN1, FN2, and FN3) in the state of semi crystal. Nylon-6 nanofibers can be used for applications in medicine, air filters, and electrode for capacitors

Abstract:
Gravity measurement has been conducted in South Lampung area to study the characteristics of the distribution of bedrock and igneous rocks, especially those that can be utilized for development in the National Strategic Area of the Sunda Strait. This study uses a 2D qualitative modeling method and utilizing spectrum analysis of complete Bouguer anomaly data. Based on the result of modeling of residual gravity anomaly, it was found that the intrusion pattern on Sulan granitoid pluton and surrounding plutons showed a significant intrusion of the body and scattered in some Tarahan area. 2D qualitative modeling shows Paleozoic metamorphic rocks are responsible as bedding rocks, and the spread was identified scattered throughout the study area, although it cannot be ascertained whether the bedrock in the Bakauheni area is precisely the same rock as the bedrock in Tarahan area. Meanwhile, Quaternary volcanic rocks are still dominated by tuffaceous sandstone and breccia. This method also confirms that andesite lava is commonly found as a product of the eruption of Mount Rajabasa and Pre-Rajabasa in the Bakauheni region. Nevertheless, some potential of basaltic andesite rocks can be obtained in monogenetic volcanic zones exposed around the foot of Mount Rajabasa.

Abstract:
The test of critical thinking skills in specific topics in physics is still rarely. This study aimed to develop a specific test in critical thinking skills in the kinetic theory of gases (CTKTG) and also to assess the students' critical thinking skills. This study used the 4D method (Define, Design, Develop, and Disseminate). The CTKTG test was initially tested in four sample groups: interviews with an expert review (N = 3), professional physics teachers (N = 2), and graduate school students (N = 2), students from secondary schools (N = 29). The test was modified based on the revised results in the initial test. After that, the test was given to a group of students in class XI, who were science students (N = 55). The results showed that internal consistency from the CTKTG test was α = .89 (good). The implementation strategies and tactics are the most difficult aspect of critical thinking skill with a mean of 1.37 (very low) and basic classification is easiest with a mean of 2.84 (average). So, the findings showed that the CTKTG test can be used to measure students' critical thinking skills on the topic of the kinetic theory of gases.

Abstract:
Students' comprehension of the theory is often implemented as an effort to improve their achievements. However, other learning processes are rarely carried out by teachers, such as the practice or tools uses as the lesson application. The purpose of this study is to analyze the learning effectiveness by applying the geophysical surveys practice method or the use of environmental geophysics tools. The assessment of students' abilities is based on the interpretation results of environmental geophysical survey data and the presentations and discussions about the results of interpretation. The TGT Cooperative learning model was used with a quasi-experimental method and quantitative design. Data collection was carried out using a series of research instruments in the form of questionnaires. The results of the study were based on comparisons between the experimental class and the control class. The results show that the experimental class has excellent findings. 1) Based on the results of the post-test, the TGT cooperative learning method is very effective in this study, because teamwork can maintain students' enthusiasm and understanding during the learning process. 2) Retrieval of field data makes students better understand the application of geoelectric concepts and determination of rock resistivity.

Abstract:
The use of mobile phones for learning is still becoming a debate in Indonesia. Many schools forbid their students to bring mobile phones to school. This study was aimed to describe the perceptions of physics teachers in Lampung Province regarding the use of mobile phones to study physics. Data was collected from 39 physics teachers from various districts in Lampung Province. The Likert scale with a range of 1 to 5 was used. Descriptive quantitative data analysis was carried out. The results showed that most teachers agree /strongly agree: (1) to utilize mobile phones in learning physics both inside and outside of the classroom, (2) the tendency of students to use mobile phones make the physics learning process efficient. It could strengthen and improve the quality of the learning process. Almost all physics teachers agree /strongly agree with mobile phones usage, because: (1) it could turn the learning process from teacher-centered into student-centered and from content-oriented learning to process-oriented learning, (2) it could improve efficiency and productivity in the learning process. However, they agreed that the use of mobile phones by students could not replace the teacher's role, so physics teachers needed a more sophisticated concept of cellular learning to be implemented
