Abstract

Telah dilakukan penelitian yang bertujuan untuk mengetahui pengaruh dosis paparan dan indeks eksposi pada pemeriksaan thorax terhadap IMT pasien dewasa. Data peneltian yang digunakan pada saat pengamatan adalah berat dan tinggi badan pasien, faktor eksposi yang terdiri dari tegangan (kV), Arus (mA) dan waktu (s) serta nilai FFD pada saat pemeriksaan. Pengambilan data dengan menggunakan jenis pemeriksaan thorax Posterior-Anterior (PA). Rentang usia pasien yang digunakan saat penelitian sesuai dengan aturan DEPKES pada kategori dewasa yaitu 26-45 tahun. Pengujian pada data menggunakan uji-F dengan taraf signifikansi 0,05. Berdasarkan hasil pengujian data menggunakan uji-F diperoleh nilai signifikansi sebesar 0,000 dan nilai Fhitung sebesar 49,166 dengan nilai taraf signifikansi 0,05 dan nilai Ftabel sebesar 3,35. Dari hasil tersebut dinyatakan memenuhi kriteria pengujian dalam statistik dimana H1 diterima dan H0 ditolak, sehingga dapat disimpulkan bahwa terdapat pengaruh pada nilai dosis paparan dan nilai indeks ekposi terhadap Indeks Massa Tubuh (IMT) dimana nilai indeks eksposi berpengaruh terhadap hasil citra pesawat sinar-X pemeriksaan thorax.

Abstract

The title of this paper is Fraunhofer diffraction simulation using spreadsheet and GNU octave media as an alternative for learning during the pandemic. This paper aims to present an alternative to distance learning during the COVID-19 pandemic by using simulations using spreadsheets and GNU Octave media.Optical practicum in physics laboratories can not be done during pandemics. So the solution that can be offered is to use simulations on optical subjects of diffraction material. In the simulation making activities students can learn and explore about the phenomenon of diffraction. Simulations using the equations used in the research of Zhanget al. in 2013.This simulation is used to visualize the effect of variations in different parameters such as wavelengths and gap widths in Fraunhofer diffraction patterns. This paper has successfully simulated Fraunhofer's diffraction using spreadsheets as well as GNU Octave. This distance learning allows students to develop fraunhofer computational computational skills and conceptual understanding of diffraction

Abstract

This study aims to improve the competence of prospective teacher students through the 2nd Batch Teaching Campus Program in 2021 at SMPN 19 Mataram. This activity was carried out at SMPN 19 Mataram with a total of 8 students from 5 study programs at FKIP University of Mataram. The activity was carried out for 5 months, with a total implementation time of 20 weeks starting from August to December 2021. This type of research is quantitative research. Data on improving the competence of prospective teacher students was obtained from a questionnaire with an assessment using a scale of 4. The number of questions in the questionnaire was 25. The competency criteria consisted of four categories, namely Very good (A), Good (B), Enough (C), and Poor (K). The increase in student competence from week 1 to week 20 is calculated using N-gain. The average value of student teacher competency is 83.7, which is in the Good (B) criteria. The N-gain value obtained is 70.7 which is in the high criteria. Thus, the competence of prospective teacher students will increase through the 2nd Batch Teaching Campus Program in 2021 at SMPN 19 Mataram.

Abstract

This study aims to determine student responses to the implementation of online semesters in basic physics courses. The subjects of this study were first semester students as many as 28 students. The instrument used is a questionnaire of 5 statements answered via google form. Then the answers to the questionnaire were analyzed using a qualitative description, the data of which was written in a table. Based on the results of data analysis, the percentage of student responses to the online basic physics course semester is 83%. Based on the percentage, this shows that students give a positive response to the semester of basic physics courses.

Abstract

The study, entitled "Application of the Problem Base Learning Model in Science Lessons at SMPN 3 Selong" aims to determine the influence of students in  understanding  the  concept  of  learning  science  in  the  classroom.  The research subjects were students of class VIII at SMPN 3 Selong, namely class VIII A and class VIII B, with the data retrieval process using a written test of 5 items of description. The average value obtained in the control class is 65.48 while the experimental class is 85.48 with a difference of 20 points. For the hypothesis value   = 2.042 while   = 1.079 from the results of the calculation of the hypothesis test results of learning science students obtained  >  =, then the hypothesis alternative (Ha) is accepted. So it can be concluded that there is an influence in the application of the Problem Base Learning model in science learning at SMP 3 Selong

Abstract

This development research aims to produce a product in the form of a physics learning device with a problem based learning model on Momentum and Impulse material to improve students' higher-order thinking skills. The type of research is Research and Development (R&D) with a 4D model consisting of Define, Design, Develop, and Disseminate. The products developed are syllabus, online learning implementation plans, student worksheets equipped with PhET simulation instructions, and higher order thinking ability test instruments. Product validity was assessed by five validators with Likert scale analysis. Furthermore, the effectiveness of the device is determined from a limited trial to get the N-gain value. The results of the study based on the validator's assessment showed that the overall device developed had an average value of above 3.00 in the good category, then the average N-gain test results obtained a value of 0.34 in the medium category. Thus, it can be concluded that the development of problem based learning physics learning tools on Momentum and Impulse material is valid, and effective for improving students' higher order thinking skills.
