Abstract

The Partnership for 21st Century Learning (P21) developed the Framework for 21st Century Learning to help education practitioners integrate skills into lesson teaching. This framework describes the skills, knowledge, and expertise that students must master in order to succeed in work and life. One of the skills that must be mastered by students in facing the 21st century is the 4C skill which consists of critical thinking, communication, collaboration, and creativity skills. This study aims to analyze the growth of the 4C skills of SMK students as the effect of implementing the use of PjBL STEM-based digital physics modules. This research is an experimental study with the before-after method, which compares the conditions before and after the implementation of learning activities. Data was collected by filling out a questionnaire with a Likert scale by students. The results showed that the 4C skills of vocational high school students grew significantly.

Abstract

The properties of neutron star’s inner crust have been investigated using the Compressible Liquid Drop Model, particularly around the neutron drip density region, which is the boundary between the outer and inner crust. Symmetry energy in the equations of state SLy4 and BSk3 was calculated to determine the density data between the outer and inner crusts.  The properties of the inner crust can be understood through parameters such as the change in the number of nucleons in the atomic nucleus, the asymmetry parameter in surface energy, and volume energy. It was shown that the choice of the symmetry energy expansion coefficient (L) of order-1 results in a distinct energy range of 9-11 MeV within the neutron drip region. This contrasts significantly with the energy symmetry observed around saturation density, which reaches (30 ± 4) MeV in the reference models used. Furthermore, it was found that symmetry energy affects the neutron composition in the inner crust. As the density increases, neutron numbers rise, while proton counts exhibit relative stability within the range of 40 to 50 for each atomic nucleus. Importantly, we observe a marked decrease in proton fraction at the onset of the neutron drip region, where ???? ≅10 MeV, suggesting electron capture processes transforming protons into neutrons. This phenomenon contributes to the presence of neutron and free neutron gas layers within the inner crust.

Abstract

Indonesian clay, with red color type was one kind of clay with wide distribution and yet to be well managed. The clay can be used as natural coloring material as a substitute for the textile dyes. This study aims to determine the effect of soaking time on the color produced and the effect of clay solution composition on the color produced. The variable used in this research is the variation of the solution composition (1kg/ 1 L, 1kg/ 2L, 1kg/ 3L) and variation of soaking time (24 hours, 48 hours, and 72 hours). The results of the research show that on the solution composition variation obtained the most concentrated color at 1kg/ 1L solution, and at the soaking time variation obtained the most concentrated color at 72 hours with the intensity of light that can penetrate the fabric is very small.

Abstract

Lighting in the bedroom is important in maintaining the quality of children's sleep. At the age of 0-5 years, a child has a sleep duration of around 11-18 hours, so it is necessary to pay attention to the lighting in the bedroom so that children have quality sleep time. This study aims to determine the effect of lighting in the bedroom on the sleep quality of children aged 0-5 years. Samples were taken randomly with the age range of children 0-5 years with the criteria of children accustomed to sleeping with the lights off as many as 6 samples.  The number of samples was adjusted to the availability of samples around the research site in Tinjomoyo village. Data collection techniques were observation and questionnaires. The parents of the sample filled out the observation sheets and questionnaires. The duration of data collection depends on how many times each sample wakes up during sleep at night, starting when the child falls asleep until 03.00 AM. The results showed that there was an effect of bedroom lighting on the sleep quality of children aged 0-5 years as indicated by a change in the child's total awakening, which is an average of 2 fewer awakenings during sleep from the lights on to the lights off.

Abstract

The purpose of this study was to identify the science process skills of physics education students through analysis of practicum reports on wave courses at the Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang. The research method used is qualitative descriptive. The entire population in this study is used as a sample. Therefore, the sample in this study consists of third-semester students for the 2022/2023 academic year in the Physics Education program, totaling 94 students into 3 classes: A, B, and C. Observations indicate that the wave practical sessions are conducted using an open inquiry approach, without any practical guidance modules. The assessment of practical reports is conducted according to the predetermined evaluation rubric. The students' science process skills in preparing wave laboratory reports are categorized as high. Analysis results show that the highest average percentage of science process skills is found in the grouping indicator, at 88.32%, while the lowest is in the hypothesizing indicator, at 73.72%. The lecturer is assisted by laboratory assistants in evaluating the students' practical reports, with the assessment based on the results obtained in the report preparation. Students are considered to be in the high category if they are able to prepare reports according to the systematic report structure and meet the science process skills criteria.

Abstract

This study discusses the utilization of gadgets used for virtual practicum in order to obtain data on students' conceptual understanding in physics subjects with electricity material. This study aims to determine the understanding of students' concepts in physics subjects. Student understanding of concepts was obtained by comparing knowledge before and after the treatment is carried out. This type of research was quantitative research, with sample of class XII MIPA MAN Kendal students. Data processing techniques used pretest data and posttest data between the experimental class and the control class. The average result of the experimental class was 0.28 with the low N-gain category and the average control class was 0.16 with the low category. However, the average N-gain in the experimental class is close to the medium category, thus the average level of understanding of the concept in the experimental class is higher than that of the control class.

Abstract

Students have difficulty understanding abstract physics concepts because they are difficult to visualize. Based on the results of observations, students’ critical thinking skills are not yet improved and the learning process is still conventional. The use of learning media based on Smart Apps Creator by integrating the PBL learning model aims to improve student’s critical thinking skills. Based on the developing of ADDIE model, this study is development research or Research and Development (RD). During the 2022–2023 academic year, class XI–3 students at SMA Negeri 1 Kembang were the subjects of this study. The validation results by material experts were 88.75% and media experts were 89.38% in the very feasible category. Learning media based on Smart Apps Creator (SAC) is effective to improve student’s critical thinking skills as shown by the higher percentage of N-Gain test results for the experimental class, namely 76.82% with effective criteria, compared to the control class of 56.46% with quite effective criteria. Analysis of the profile student’s critical thinking skills after the action was shown by observation results of 84.52%. This shows that students in this class can improve their critical thinking skills.
