Abstract

Model Thomas-Fermi-Dirac-von Weizsacker merupakan perluasan dari model Thomas-Fermi dengan menambahkan koreksi suku exchange dan koreksi gradien energi kinetik. Metode yang digunakan dalam penelitian ini adalah Metode Langsung (Direct Methods). Penerapan metode ini dalam Teori Fungsional Densitas berarti bahwa profil densitas pada keadaan dasar dapat diperoleh secara langsung melalui analisis fungsional energi sistem terkait, tanpa menyentuh persamaan Euler-Lagrange, seperti yang sudah biasa dilakukan. Penerapan pada kristal NaCl menghasilkan gambaran batas atas minimizer yang berupa suatu fungsi sehingga disebut sebagai fungsi payung.

Abstract

Gypsum is derived from pure calcium sulfate dehydrate which is a common material that is commonly used in denture manufacturing process. This study aimed to know the difference on compressive strength and dimensional change of commercially type III gypsum compared to recycle type III gypsum to produce working cast. The type of research is laboratory experiment. A total of 40 samples for each test is divided into five groups which consists of commercial type III gypsum, pure recycled type III gypsum, pure recycled type III gypsum with 10%, 20%, 30% type III commercial gypsum. The difference on compressive strength and dimensional change between the groups was analyzed using one way ANOVA and is them tested with LSD test. The result showed that there was a significant difference (p<0,05) between compressive strength and dimensional change of commercial type III gypsum compared to pure recycled type III gypsum and pure recycled type III gypsum with 10%, 20% and 30% type III commercial gypsum. In conclusion, addition of 30% commercial gypsum in recycled gypsum the compressive strength was higher than other recycled gypsum types.

Abstract

&nbsp;&nbsp;&nbsp;&nbsp; This research aims to revealing profile of science process skills, profile of questions, and structure of conceptual presentation in physics textbooks on the subject of optical tools. The research method used is descriptive analysis with a quantitative-qualitative approach. Sample of this research are two physics textbooks based on the 2013 Curiculum those widely used as learning resources in Cilacap district. The results showed that both textbooks on the subject of optical tools more present aspects of basic science process skills than integrated science process skills. The percentage aspects of basic science process skills is 72,88% for book A and 87,32% for book B. Questions are more dominant to train students at the level application (C3) with percentage 66,67% for book A and 71,37% for book B. The structure of presentation of the concept in book A prepared directly on the discussion of optical tools, whereas in book B is explained about reflection and refraction firstly, then review the material of optical tools.

Abstract

Some of Physics Science material in Junior High School are abstract so that sometimes students find difficulties in understanding them because there is no clear visualization of the material. Those things can be overcome by using a learning media. Scrapbook is a craft that contains images and a little narration which can help teachers in explaining some of the Physics Science material that requires a good visualization. This study aimed to develop scrapbook learning media and find out the effect of the learning media on students' material understanding. The method that was used in this research was Research &amp; Development (R &amp; D). The sample of this study were 27 students of VIIC class of SMP Negeri 1 Sigaluh using pretest-posttest and feasibility questionnaires. The data analysis techniques used t-test to see the difference between students? learning result before and after the use of scrapbook as a media in the learning activities. Moreover, an N-gain test was also performed to calculate the amount of increase that was occured. The results of this study showed that scrapbook learning media did not only emphasize on the clear and interesting images, but also provided enough materials so that the media can be used for independent learning. The results of the feasibility test by material experts and media experts obtained an average score of 91.26% with a very feasible category. Scrapbook media was able to give an influence to the enhancement of students? material understanding by obtaining an N-gain value of 0.54 with a medium category.

Abstract

All types of selection test for state universities are accompanied by intense competition levels. SBMPTN is one of this test that provides the highest quota of prospective students. Some questions tested require high order thinking skills while students are accustomed to work on low order thinking skills on their high school. The challenge for students is the students have to know the type of questions tested in SBMPTN and accustomed to work the kind of questions. This study aimed to find out the cognitive level classification in SBMPTN physics problems based on revised Bloom?s taxonomy and characteristics of SBMPTN physics problems based on indicator of critical thinking skill and problem solving skills. This study was qualitative research using SBMPTN physics problems code 402 in 2018, as its subject. The result of this study showed that in 2018 there were 73.33% SBMPTN physics questions included HOTS categories.&nbsp; In addition, it obtained that in 2018, SBMPTN physics problems contained critical thinking skills of 80%. Furthermore, the availability of problem solving skill?s indicators in the SBMPTN physics question was found to be 60%.
