Kelengkapan fasilitas laboratorium sangat membantu proses belajar mengajar di sekolah, dan karena itu guru harus mampu berinovasi dan kreatif dalam mendain peralatan laboratorium fisika yang sederhana namun memenuhi standar kelayakan penggunaannya. Penelitian ini adalah sebuah penelitian rekayasa atau rancang bangun dengan menggunakan pendekatan Forward Engineering. Alat lab sederhana yang telah diproduksi kemudian diuji coba melalui dua tahapan, yaitu uji ahli untuk mengetahui tingkat kevalidan alat dan uji mandiri untuk mengetahui keberfungsian alat lab fluida dinamis yang didahului dengan kajian awal studi literatur. Pengambilan data dilakukan dengan eksperimen, uji validasi awal dan uji validasi akhir oleh ahli materi dan ahli media. Hasil pengujian alat praktikum fluida dinamis memilki pesentase kesalahan paling tinggi 3,04 % sedangkan hasil validasi akhir untuk ahli materi dan ahli media untuk alat dan penuntun praktikum fluida dinamis berada pada kriteria tingkat kelayakan 81%- 100%. Berdasarkan hasil penelitian dapat disimpulkan bawa telah dihasilkan peralatan praktikum fluida dinamis dengan kualifikasi valid atau layak.

This study aims to improve student learning outcomes using the Kinemaster and Quizziz applications using classroom action research methodology. In the current coronavirus disease 2019 pandemic situation and the very rapid development of ICT, learning physics using the Kinemaster and Quizziz applications can be one of the learning media that can be used in the teaching and learning process of physics to improve student learning outcomes by creating a pleasant learning atmosphere. This study uses the Class Action Research (CAR) method for students of class X MIPA II SMA Negeri 2 Langowan. With the number of students 19 people. The results of the evaluation of teaching and learning activities at the stage of the first cycle showed the value of classical X MIPA II students' learning outcomes that was 100%, where there was only 1 student whose learning outcomes were categorized as moderate, 8 students whose learning outcomes were categorized as high and 10 students whose learning outcomes were categorized very high. The results of the research obtained in the learning process using the Kinemaster and Quizziz applications on the material of straight motion can improve the learning outcomes of students of class X MIPA II at SMA Negeri 2 Langowan.

The purpose of this study is to explore the concept and scientific process of the phenomenon of changes in air temperature and soil temperature in vegetation land, open land, and asphalt roads. This study uses a qualitative and quantitative approach. The exploratory research used by the research team is themodel Higher Orther Thinking Learning in Democratic Interactionwhich (HOTL-DI) Type A emphasizes interactive components, individualistic high-level learning processes and democratic interactions as a process of sharing and cooperation between individuals in groups. The first stage of object exploration (changes in air temperature and soil temperature in vegetation land, open land, and asphalt roads), concepts and scientific processes is carried out by the research team under the guidance of the thesis supervisor. The second stage is exploratory research on fourth semester students majoring in physics education for the 2021 academic year. The stage of exploring physics objects, concepts and processes in groups as democratic interactions. Democratic indicators, formulated by researchers based on the condition of group interaction when exploring objects and discussing in group report preparation. Students experience difficulties at the beginning of exploration activities because they lack experience in exploring physical concepts and processes about natural phenomena. Democratic behavior and exploration activities seem to be getting better over time, so this learning can realize learning activities to explore objects, concepts and science processes in democratic interaction learning well.

This research aims to determine the effectiveness of student learning outcomes using PhET simulation material on the principle of continuity for class XI students at SMA Negeri 1 Likupang. This research uses an experimental method with a Two Group design using Post-test Control Group Design. The sample for this research was taken from class XI MIA 1 as an experimental class which was taught using PhET Simulation with a total of 20 students and class The second class is homogeneous and equal. The data taken in this study came from the same post-test in both classes. The average post-test score for the experimental class was 87.35 and the post-test for the control class was 70.7, which means that student learning outcomes in the experimental class were higher than student learning outcomes in the control class. The research results were analyzed using the t-test with a significance level of 0.05, obtaining a value of tcount = 7.763 > ttable = 1.686, so H0 was rejected and H1 was accepted. Meanwhile, for the N-Gain Test, the percent obtained was 76, which is within the effective criteria. From the results of this research it can be concluded that the use of PhET simulations is effective on student learning outcomes in material as continuity.

The mathematical model for paratrooper motion is formed based on Newton's Second Law where the change in momentum in a system is equal to the resultant force acting on it. This research is an experiment with analytical descriptive method, which aims to show which method is most effective for the root solution of the equation in determining the drag coefficient (c) of the parachutist's motion numerically using the graph method, the method for two, the false position method, the Newton- Raphson and the Secant method. Numerical analysis using Borland Delphi 7 program and data processing using Microsoft Excel program. The results showed that the graph method is only limited to determining the estimated value for the lower and upper limits that will be used in the method of the two-way method, the false position method, the Newton-Raphson method and the Secant method. It turns out that the Secant method is a more effective method in determining the drag coefficient (c) of the parachutist's motion, because there are only 4 iterations to obtain a c value of 16.8345.

Guided inquiry encourages students actively identify problems, create hypotheses, conduct experiments, analyze data, and draw conclusions. Tracker helps students understand physics concepts by analyzing objects in parabolic motion, and visualizing relation between variables through graphs and tables. This study aimed to examine effect of guided inquiry model with Tracker on high school students’ learning outcomes in parabolic motion. The method used Quasi-Experiment with pretest-posttest control group design. The population is 11th-grade students at SMA Negeri 1 Kawangkoan Barat with samples experimental class XI A and control class XI B.The test instruments included multiple-choice and essay questions. After treatment, the experimental class's average score showed significant increase 54 to 81, higher than control class 50.75 to 66.25. Hypothesis testing (SPSS) led to rejected H0 and H1 accepted. Its concluded that guided inquiry with Tracker positively affects learning outcomes by boosting student engagement and comprehension.

Physics learning in university is often theoretical and lacks a contextual approach, making it difficult for students to understand concepts in depth. Thematic-Explorative-Democratic Learning (TED) is an approach that emphasizes the exploration of real experiences and democratic interaction. This study aims to determine the results of physics concept exploration and democratic interaction of students through the application of TED learning themed traditional games cenge-cenge. The research method used is descriptive qualitative with data collection techniques through observation, exploration sheets, and democratic interaction assessment sheets. The results show that students are able to identify various physics concepts such as Newton's laws, gravity, parabolic motion, rigid body equilibrium, friction, and momentum. Democratic interaction is seen from active collaboration between students across semesters. It is concluded that TED learning based on traditional games is effective in improving contextual physics understanding as well as student participation and cooperation.
