Numerical methods are used to solve the differential equations in the case of a damped pendulum system. In this paper, we aim to solve the equation of dumped pendulum motion using some numerical. Four numerical methods are decomposed, each the Euler method, fourth-order Runge-Kutte, Odeint provided in Python, and Neural Network scheme. All answers obtained are approximations or predictions that include errors. The error of those methods will be compared with the analytical solution of the case, known as the global error. The Odeint and fourth-order Runge-Kutta methods are more accurate than the other methods. The Odeint is built from the Runge-Kutta fourth-order method.The Neural Network method has less accuracy than Runge-Kutta, but the error obtained is still within acceptable tolerance limits.

Low English skills can have an impact on various things related to students' academic progress. One of them is that students have difficulty accessing various international learning references written in English. This research aims to develop an interactive module to support English lectures for physics in the Physics Education Study Program, Ganesha University of Education. Development of interactive modules as a solution to provide adaptive and effective physics English lecture teaching materials to increase students' motivation in attending lectures. Specifically, the objectives of this research include 1) describing the validity of the interactive module being developed; 2) describe the level of practicality of the interactive module being developed; 3) describe the effectiveness of the interactive module developed in increasing student learning motivation. This research uses development research methods with the ADDIE model (Analysis, Design, Develop, Implement, Evaluation).

PENGEMBANGAN E-LKPD FISIKA BERBASIS PROBLEM BASED LEARNING BERMUATAN PENDIDIKAN KARAKTER UNTUK PESERTA DIDIK KELAS XI DI SMA N 12 PADANG

In the learning process students can be said not to be active. The learning process still uses printed teaching materials such as textbooks and LKS. The learning model is in the form of lectures and questions and answers. Along with technological developments, the learning process must be able to utilize technology, such as the formation of teaching materials. One of the teaching materials developed is in the form of E-LKPD. The purpose of this study was to develop a valid and practical E-LKPD Physics Based on Problem Based Learning with Character Education for Class XI Students at SMA N 12 Padang. This type of research is development (Research and Development) using the 4D development model. The instruments used were validity and practicality sheets, used to determine the validity and practicality of the teaching materials developed. The percentage level of validity is based on material experts and media experts, the validation average is 89.77% which is categorized as very valid. The practicality percentage of the media is 92% which is categorized as very practical. So that the teaching materials developed are categorized as very valid and very practical to use in the learning process.

The learning process is still not optimal because the learning models and media used are still conventional. This study aims to determine the effect of the discovery learning model on student learning outcomes on pressure material with the help of Phet Interactive Simulation Media at SMP Negeri 13 Medan. The method and design used is pre-Experimental Design with One-Group Pretest-Posttest type. The population of this study is all students in class VIII with the research sample is class VIII-4 with the sample technique is purposive side. The results of hypothesis testing analysis obtained t count = 16.11 with a significant level of 5% and t table = 2.04, then Ha is accepted and Ho is rejected. The average obtained on the pretest was 28.5 on the posttest 70.17. Furthermore, to determine the effect of the discovery learning model on student learning outcomes, a regression test was conducted with the equation Y = 27.32 + 0.62X. It can be concluded that there is an influence and improvement in the learning outcomes of students in class VIII-4 SMP Negeri 13 Medan after using Phet Interactive Simulatin media in the discovery learning learning model.

Penelitian ini bertujuan untuk menganalisis perbedaan kemampuan Higher Order Thinking Skills (HOTS) antara siswa yang dibelajarkan dengan model Problem Based Learning (PBL) dan siswa yang dibelajarkan dengan model Direct Instruction (DI). Penelitian ini menggunakan jenis penelitian quasi eksperimen. Desain penelitian pretest – posttest non equivalent control group design. Sampel penelitian diperoleh menggunakan teknik sampling jenuh. Jumlah sampel sebanyak 43 siswa yang terdistribusi ke dalam dua kelas. Data HOTS siswa diperoleh melalui hasil pretest dan posttest siswa. Semua pengujian hipotesis dilakukan dengan taraf 5%. Hasil penelitian menunjukkan bahwa uji normalitas dan homogenitas kedua kelompok > 0,05. Dengan demikian, data N-Gain score dinyatakan terdistribusi normal dan memiliki varians data homogen. Selanjutnya, hasil uji-t kemampuan HOTS siswa yaitu 0,000. Dengan demikian, data N-Gain score < 0,05, maka H0 ditolak dan Ha diterima sehingga dapat disimpulkan bahwa terdapat perbedaan kemampuan HOTS antara siswa yang dibelajarkan menggunakan model PBL dan siswa yang dibelajarkan menggunakan model DI.
