Abstract

This study aims to find the effectiveness of forming a Pancasila student profile by applying a project based learning model in the physics learning process for Newton's Law material in class X MIPA students at SMAN 1 Bajawa. The dimensions of the Pancasila Student Profile include three dimensions, namely the ability to think critically, creatively, and mutual cooperation. This type of research is a mixed method sequential explanatory. Data collection instrument were tests and observation guidelines. The results of the data analysis show that the project based learning model contains Pancasila student profile values. Based on the research data, it was obtained that the students’ abilities on the Pancasila student profile is in the good category. The ability to critical thinking and crietive thinking has increased and can foster an attitude of mutual cooperation in students after being treated using a project based learning model. The N-gain value of critical thinking is 64.3% and classic completeness is 93%, the N-gain creative thinking increases by 68.5% and classic completeness is 90%, the students' cooperative attitude is 83% in the good category. This shows that the project based learning model that was implemented is effective in strengthening the profile of Pancasila students.  The class control uses the  PBL model N-gain value of critical thinking was 57.7%, the N-gain creative thinking increased by 53.3%, the mutual cooperation attitude of the students was in the with the medium category.

Abstract

Over the past decades, photonic crystals have emerged as interesting photonic structures. It plays a vital role in many fields of optical communication, biomedical sensing, and other applications due to its compactness, high sensitivity, high selectivity, fast responsiveness, etc. Strong light confinement in photonic crystals and adjustment of its geometrical parameters have led to the emergence of photonic crystal biosensors. Biosensors are extensively employed for diagnosing a broad array of diseases and disorders in clinical settings worldwide. Photonics crystal-based biosensor is one of the solutions to detect various diseases. By using literature review method, this paper aims to explore applications of photonic crystal-based biosensors to encounter the sensitivity of various biomolecules for cancer, malaria, and blood components detection.

Abstract

This research aimed to describe the validity of a numeracy literacy assessment instrument of electromagnetic induction based on minimum capability assessment (MCA) which was develop using Rasch model analysis assisted by Winstep software. The research employed the research and development design with a modified Mardapi model. The instrument was constructed by developing fifteen questions. The analysis of the instrument was utilized to measure the construct and item validity, reliability, item difficulty level, and item discriminatory. This research involved 32 participants in the small-scale test and 206 participants in the large-scale trial. The test result showed that the fifteen questions were suitable to use because it has values that meet the criteria for all measurement variables both on small scale and large-scale tests and could be assess students' numeracy literacy skills.

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.
