<![CDATA[Inter-Semester Lectures are identical students whose level of mastery of concept skills is still low. Efforts that can be made to improve students' mastery of concepts are applying learning with the cognitive conflict approach. Students have a very low understanding of concepts in basic physics subjects in temperature and heat. The purpose of this study is to improve the mastery of the concept of students in the material Temperature and Heat. This type of research is a quasi-experimental design with the One Group Pretest-Posttest Design. The sample in this study used students of physics education study programs at one of the universities in NTB. The number of samples in this study was 20 students. The research instrument used was a multiple-choice question. Improved understanding of concepts was analyzed by the N-Gain test. The results showed an increase in mastery of the concept of material temperature and heat after learning with the cognitive conflict approach with an average N-Gain of 0.62 in the medium category DOI: 10.29408/kpj.v4i1.2009]]>

<![CDATA[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.]]>

<![CDATA[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]]>

<![CDATA[The earthquake was the most common natural disaster in Indonesia, one ofwhich was the Province of Bali. The southern part of Bali is a meeting area of two earth plates (subduction zones) between the Eurasian and Indo-Australian plates and in the northern region there is a back arc thrust fracture which results in earthquake frequencies in the Bali area. One of the parameters that is very instrumental in determining the level of damage to land and buildings that occur on the surface of the earth due to earthquake shocks is the acceleration of the soil. A research has been conducted which aims to find out the empirical equation of land acceleration for Bali in the 2008-2016 period, namely by determining the empirical equation of land acceleration (PGA) conducted using magnitude parameters, hypocenter distance and PGA (observation) values in 2008-2016 with coordinates 70-120 LS and 1130-1180 BT. Through the regression analysis approach, to obtain the empirical equation of land acceleration in the Bali region is ð‘™ð‘œð‘”10(ð‘ƒðºð´) = (−1,89) ð‘™ð‘œð‘”10(ð‘…) + (0,71) ð‘šð‘ + 1,18. Then several approaches and correlation analysis are performed to see the compatibility of the new empirical equation with the existing one.]]>

<![CDATA[From the observations in SMP Utama Wacana III Tulang Bawang Barat, the motivation of the students is very low, so the students' learning activity is low to. This problem appears when the teacher explains the teori, some students are drowsy, daydreaming, there is also chatting with his friends. This study aims to determine the effect of student learning activities with the provision of motivation in the form of written media in the form of bulletins and posters. The research method is experimental method using two classes, that is experiment class and control class. The data collecting is done by posttest only control group design. From the results of research conducted, it was found that the average learning activity that was given the motivation to use the media in the form of bulletin and poster higher than the average of learning activities that are not motivated using the media in the form of bulletins and posters with test data difference of two average obtained t -hit = 3.95 and t-daf = 1.68, showing t-hit> t-daf. So it is important if in the classroom given posters that can motivate students and if you can add with articles that can increase student motivation as well, awareness for learning increases so that student learning activities increase.]]>
