This study aims to examine the effect of the SSCS (Search, Solve, Create, and Share) learning model assisted by e-LKPD on students’ mastery of physics concepts. The type of research used is quasi experiment with nonequivalent control design. The population in this study were all students of class XI SMAN 1 Lembar consisting of four classes. The sampling used purposive sampling technique and obtained students of class XI MIPA 1 as experimental class and XI MIPA 3 as control class. Data collection techniques using multiple choice tests to measure the mastery of physics concepts of students. The data obtained were analyzed using an independent t-test with the help of excel. The results showed that there was a significant difference in the mastery of physics concepts between students who used the SSCS learning model and students who used conventional learning models. This is shown from the acquisition value of tcount 2.21> ttable 1.67 so it can be concluded that there is an effect of the SSCS learning model (search, solve, create, share) assisted by e-LKPD on the mastery of physics concepts of students.

Vectors are fundamental concepts in mathematics and physics that play a crucial role in various scientific and engineering applications. This study investigates the relationship between the angle and magnitude of the resultant force vector using the Cookbook Laboratory practical approach. The experiment involved combining two forces at different angles and measuring the resultant force. The results indicate a linear relationship between the angle and magnitude of the resultant force, suggesting that as the angle increases, the magnitude of the resultant force also increases. However, this finding contradicts the theoretical prediction of an inverse relationship. This discrepancy is attributed to experimental limitations, particularly parallax error, which may have affected the accuracy of the measurements. Further experiments are recommended to minimize parallax error and obtain more accurate results. A thorough understanding of vector concepts and measurement techniques is essential for comprehending the relationship between angle and resultant force magnitude.

Analisis Faktor yang Menyebabkan Penyimpangan Galvanometer dan Kondisi Lampu dengan Hukum Faraday Menggunakan Laboratorium Virtual PhET

2024-06-24T12:36:20+01:00

This study aims to explore the concept of Faraday's Law by allowing us to understand what factors can affect the deviation of the galvanometer needle and lamp conditions. The method used is experimental method using PhET virtual laboratory. This study shows that there are factors that affect the deviation of the galvanometer needle, namely the orientation of the poles on the magnet that is moved near or away from the coil. The factors that affect the condition of the lamp are the number of turns on the coil and the speed of the magnet movement when approaching or moving away from the coil.

Keywords: EMF, Faraday's Law, PhET Virtual Laboratory.

Analisis Pengaruh Ketinggian Lintasan Terhadap Gaya Gesek dan Kecepatan Benda Pada Bidang Miring Menggunakan PhET Simulation

2024-06-24T12:07:59+01:00

Physics is an empirical science, meaning that physics is based on observation and experimentation. One of the fundamental concepts in physics that is the foundation for many calculations is the law of mechanical energy conservation, especially on inclined planes. This study aims to analyze the effect of track height on the friction force and velocity of objects when crossing an inclined plane. This research uses a virtual PhET Simulation laboratory with a virtual experimental research design. This research uses a quantitative approach, the data analysis technique uses statistical methods to determine the effect of track height on the friction and speed of objects. The result of this study is that the height of the track affects the value of the friction force, with increasing track height, the value of the friction force will decrease, this is due to the normal force acting on the inclined plane. In addition, with increasing track height on an inclined plane, the value of mechanical energy will increase. This is because the higher the trajectory, the greater the gravitational potential energy possessed by the object.

Keywords: Altitude, Inclined plane, Mechanics, Speed.

This study aims to determine the effect of temperature value on conductivity value (conduction heat rate) in conduction heat transfer. The method used in this research is an experimental method with variable temperature and variable conductivity values of materials using amrita virtual lab simulation software. The variable variation used in this study is the difference in materials using cardboard and glass with variations in voltage, current, diameter and thickness of the same material. The results of this study indicate the effect of temperature on the conductivity value, if the conductivity value of a material is small then the temperature will be large because this experiment was conducted on insulating materials on both objects. Temperature will inhibit heat transfer by conduction, it can be concluded that both materials are good heat insulators.
