This research utilizes the Sloan Digital Sky Survey (SDSS) dataset, examining 12,884 observations to explore quasars, stars, and white dwarf objects. Magnitude data and coordinates across five filter bands are analyzed, revealing unique features through statistical methods. The identification of 77,429 quasars with 15 dimensions enhances the dataset. Thorough analyses of stellar and white dwarf classes, coupled with visualization techniques, unveil variable relationships. Residual validation and Gaussian kernel density plots confirm significant class differences. Non-linear regression and a normal distribution mixture model depict complex variable relationships. A parallel coordinates plot aids in interpreting data patterns, while predictive modeling via regression exposes meaningful coefficients. Logistic regression effectively classifies astronomical objects in the SDSS training data. This research contributes to understanding celestial object characteristics, offering valuable insights for astronomers and astrophysicists in analyzing large-scale astronomical datasets.

This research aims to investigate the relationship between Confidence Interval, Hubble Parameter, Comoving Distance, and Distance-Volume Relationship, which are important equations in cosmology. The Confidence Interval equation is used to estimate the range of values for the difference between the mean redshift and Hubble parameter. The Hubble Parameter equation is used to measure the expansion rate of the universe, while the Comoving Distance equation is used to calculate the distance between two objects in the expanding universe, and the Distance-Volume Relationship equation is used to calculate the distance between an observer and a cosmic object based on the object's redshift. This study seeks to address several research questions, including the accuracy of estimating parameters using these equations and the potential for developing more precise equations. The study employs cosmological data analysis using the R program to analyze existing data and gain a better understanding of cosmological parameters. The results of this research contribute to our understanding of the nature and evolution of the universe, providing insights into the distribution of matter and the role of dark matter and dark energy in shaping the universe's evolution. By examining the relationship between cosmological parameters, this study enables us to make predictions about cosmic phenomena and improve the accuracy of future measurements. The findings of this research have implications for cosmological research and can aid in the development of more accurate models and theories in the field of cosmology. Overall, this study provides valuable insights into the fundamental equations in cosmology and their relationships, advancing our understanding of the universe's dynamics and evolution.

The structure of the vocational school curriculum is different from the structure of the high school curriculum in that the vocational school curriculum contains vocational subjects which causes students to set aside non-vocational subjects such as science. One of them is science subjects, whose role is unknowingly very important because the learning process prioritizes direct experience and does not become an important concern for students. The purpose of this study was to explore empirical data regarding the perceptions of vocational school students with the expertise of Fashion Design regarding the science learning process. So far, very few or even rare empirical reasons have been found for the perceptions of Vocational High School students of fashion skills regarding the science learning process. This research uses a type of case study research method with a quantitative and qualitative approach. The sampling process in this study used purposive sampling with participants totaling 37 students with an age range of 15-16 years. The instruments used in this study were questionnaires and interviews. The results of the study revealed that there were several different student perceptions in terms of interest, competence, effort, pressure, and values related to science learning activities in fashion design vocational schools.

The rapid development of technology today does not only require problem solving skills, other thinking skills such as computational thinking skills are needed in solving complex problems. This study aims to investigate the relationship between problem solving abilities in physics, especially vibrations and waves, and computational thinking skills. This study uses a correlation research design in which the relationship between two variables of problem-solving ability and computational thinking is observed. By using data from 21 eighth grade junior high school students who had participated in wave learning, it was found that the correlation between the two variables was in the moderate category. These data indicate that problem solving abilities contribute to students’ computational thinking skills. Discussion of the results of this study will be discussed in more detail in this article.

Understanding students’ preconceptions is an important initial step towards meaningful and appropriate physics learning. Particularly in the concept of collisions, students’ understanding of collision concepts often does not align with those established by scientists. Therefore, to explore students’ preconceptions, visual representation enables students to connect their experiences with specific concepts. This aids in revealing and diagnosing students’ preconceptions. This research aims to analyze high school students’ preconceptions regarding collision concepts by examining their visual representations. The research design employs a qualitative descriptive research design with data collection methods including observation sheets and interviews. Observation sheets containing visual representations by students are analyzed using a four-step semiotic analysis approach, while interview data is analyzed thematically. Seventy-two tenth-grade students were sampled offline using convenience sampling. The research findings reveal that students’ use of visual representations indicates diverse preconceptions about collision concepts, categorizing them at the macroscopic level. This data is examined across four categories of student visuals: (1) 11 visuals that are correct; (2) 18 visuals based on the objects used; (3) 34 visuals depicting different types of collisions; (4) and 29 visuals that are incorrect.

Preconceptions are an essential foundation for students, serving as a basis for more effective learning. In the context of climate change concepts, many students harbor misconceptions. One method to uncover students’ preconceptions is through the use of visual representations. Visual representations can elucidate students’ understanding of abstract and complex concepts. This study aims to examine and analyze the extent of high school students’ comprehension of climate change. The research employs a descriptive qualitative approach, with a population and sample comprising 63 tenth-grade science students from a high school in Indonesia. Data collection techniques included observation and interviews, with semi-structured interviews being utilized in this study. The results reveal that students have varied understandings of the concept of climate change, with many exhibiting misconceptions. The study identifies three categories of climate change concepts: (1) correct concepts of climate change, representing 37%; (2) climate change concepts based on objects, as depicted in the visualizations provided by the respondents; and (3) incorrect concepts of climate change, representing 63%. Based on empirical evidence, the students’ preconceptions of climate change are predominantly at the macroscopic level.

Sedangkan siswa yang telah mencapai ketuntasan dalam belajar meningkat dari 13 orang siswa (46,43%) menjadi menjadi 18 orang (64,3%). Namun demikian hasil belajar siswa belum seperti yang diharapkan dengan kondisi siswa yang tuntas belum mencapai 70%. Setelah dilaksanakan siklus II, hasil belajar siswa meningkat lagi menjadi 26 orang atau sebesar 92,86%. Sedangkan yang tidak tuntas hanya 2 orang atau sebesar 7,14%. Berdasarkan uraian di atas disimpulkan bahwa penerapan model pembelajaran kooperatif tipe STAD dapat meningkatkan hasil belajar siswa pada mata pelajaran Fisika kelas X-TEI 2 SMK Negeri 2 Banjar
