However, the scheme of this combination is unclear. Both type of learning need to be synchronized so that learning becomes effective. The solution is to involve technology in the learning process. Technology can be used as a learning medium and assessment. Blended learning scheme using worksheet based on PhET (Physics Education Technology) simulation was applied in Basic Physics course. This solution is expected to create link between face-to-face and online learning. Mixed methods with embedded design was applied. The population is quite small, namely 32 students so that all population is applied as a sample. Data on students' conceptual understanding were collected using a test. Class discussions became the basis for qualitative data which was further explored through interviews. Conceptual understanding was found in the high category for vector and projectile motion when taught through a blended learning scheme using student worksheets. The averages scores for vector in 1 dimension and 2 dimensions are 85.94 and 77.93, respectively. Then the average scores for the projectile motion is 80.93. Furthermore, through discussions and interviews, various misconceptions and their causes.</p>2023-06-21T23:20:40+07:00##submission.copyrightStatement##https://ejournals.umma.ac.id/index.php/karts/article/view/1796The PENGARUH MODEL REQOL (REAL QUEST OUTDOOR LEARNING) TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN HASIL BELAJAR FISIKA SISWA SMA2023-06-30T14:39:37+07:00fadilla pusvitasari Azisfadillapusvita12@gmail.comI Wayan Distrikpusvitafadilla12@gmail.comViyanti Viyantipusvitafadilla12@gmail.com<p>The goal of this study is to evaluate the impact of the ReQOL model on high school students' critical thinking and cognitive learning outcomes. This experimental research method uses pre-test and post-test questions to collect quantitative data from the results of students' critical thinking assessments. All of the pupils in the XIPA class at SMA Negeri 1 Natar made up the study's population. Purposive sampling is used to choose the research sample. Class X IPA III served as the control class in this study, and class X IPA VIII served as the experimental class. Test questions and observation logs were used to obtain the data. Utilizing independent sample T tests and effect size. According to the findings, there was a difference between students who used the ReQOL learning model and those who used Direct Instruction when learning about harmonic vibrations. This difference was based on the significance values of the test Smirnov, which were 0.076 for the pre-test and 0.167 for the post-test in the experimental class. The level of significance of the data is revealed to be 0.000 < 0.05 based on test results from an independent sample T test, indicating that the ReQOL model has a significant impact on improving high school students' critical thinking abilities and academic performance. Based on these results it can be concluded that there is an influence of critical thinking skills and student learning outcomes following the ReQOL learning model in class X IPA physics at SMA Negeri 1 Natar.</p> <p> </p>2023-06-27T00:00:00+07:00##submission.copyrightStatement##https://ejournals.umma.ac.id/index.php/karts/article/view/1760ANALISIS KARAKTERISTIK PANJAR MAJU DAN PANJAR MUNDUR PADA DIODA 1N40072023-06-30T21:52:22+07:00Mukti Alimukti.ali@uin-alauddin.ac.idFitrani Kadirfktria85@umma.ac.idMuh. Syihab Ikbalmukti.ali@uin-alauddin.ac.id<p><em>The purpose of this study is to describe the characteristics of changes in current and voltage in rectifier diodes with the 1N4007 series in the forward bias and reverse bias states and to be able to describe and explain the characteristics of the current-voltage (I-V) and 1N4007 rectifier diodes. The method used in this study is the experimental method. The equipment and components used in the research are 1N4007 diode, B10K potentiometer, 100Ω resistor, ammeter and voltmeter. The variables measured in this study are the control variable (voltage source), the measurement variable (diode voltage), the response variable (diode current strength). The relationship that is formed from the current strength and voltage on the diode is in the form of a linear curve at the voltage value below the diode working voltage, and will increase significantly when the diode voltage is at working voltage. Based on the analysis of the graph and the load line, it can be concluded that the 1N4007 diode is a diode derived from silicon material with a working voltage value of 0.6 -0.7volts and will only pass current in one direction and will not pass current in a bias state. backwards as long as the diode has not reached its breakdown voltage.</em></p>2023-06-30T21:52:22+07:00##submission.copyrightStatement##https://ejournals.umma.ac.id/index.php/karts/article/view/1733IDENTIFIKASI UNSUR TANAH LITOSOL DENGAN METODE XRF (X-RAY FLUORESCENCE) DAN FTIR (FOURIER TRANSFORM INFRA RED) BERDASARKAN TITIK ELEVASI DI DESA SAMANGKI KECAMATAN SIMBANG KABUPATEN MAROS2023-08-01T07:54:51+07:00Jumardin Jumardinjumardin.jumardin@uin-alauddin.ac.idAndi Syam Rizalandi.syamrizal@uin-alauddin.ac.idMinarti Minartiminarti.minarti@uin-alauddin.ac.idAbdul Munim Thariqabdu.thq@gmail.comNurhafida TurayniNurhafidat@gmail.comWahyullah Wahyullahwahyullah405@gmail.com<p>XRF method to determine elemental content and FTIR test to determine the nature of chemical compounds (functional groups) of Litosol soil at the slope (elevation angle) and the distance of the research trajectory lines.

In this mathematical pendulum material, critical thinking skills are needed by each student because they need to understand the concept of simple harmonic vibrations and the various components in it. This research method is conducted quantitatively correlative, which describes and investigates the relationship between variables. The correlation coefficient number in the results above shows 0.521 or a positive value, so the relationship between variables is unidirectional. This can be interpreted that the higher the critical thinking skills of students, the higher the student learning outcomes. Based on the correlation coefficient number on the research results, the level of relationship between critical thinking skills and physics learning outcomes on mathematical pendulum material is a moderate correlation. The results and discussion of the research indicate that the critical thinking skills of students have a good tendency.</em></p> <p><strong><em>keywords</em></strong><strong><em>:</em></strong> <em>Mathematical Pendulum, Critical Thinking, Correlation</em></p> <p><strong>Abstrak: Analisis Hubungan Kemampuan Berpikir Kritis Dengan Hasil Belajar Mahasiswa Pendidikan Fisika Pada Materi Bandul Matematis. </strong>Penelitian ini bertujuan mengetahui hubungan kemampuan berpikir kritis dengan hasil belajar mahasiswa pendidikan fisika pada materi bandul matematis.
