“…In general, video tracking analysis has been used in various cases, including physical phenomena, as done by Khotijah et al (2019) developed a practicum about momentum; Fitriyanto & Sucahyo (2016) designed a tracker video analysis for motion kinematics; Anissofira et al (2016) analyzed the motion of a roller coaster using a tracker with a multi-mode representation approach as a way for students to understand the concept of kinematics; Nurfadilah et al (2020) applied video tracking analysis to determine moments of inertia in video labs to increase student learning activities. This application is popular due to its open source, easy-to-use, and complete functionality.…”

Understanding the wave parameters in the ocean wave phenomenon is necessary to learn and develop the potential of ocean wave energy. Therefore, this study created a simple laboratory-scale of wave simulator that was developed using an electric motor. The various wave parameters obtained by different treatments were carried out using variations in the angle of the wedge inclination and the rotational speed of the wave generator. In this system, two pulleys of different sizes were used, a large pulley with a diameter of 20 cm and a small pulley with a diameter varying between 1.25 cm and 1.98 cm. Changing the size of the pulleys uses the principle of axial rotational motion to produce different rotational speeds. Moreover, the video tracker analysis application was used to characterize the parameters of the waves generated in the simulator that has been designed. The parameters obtained include wave height, amplitude, frequency, wave period, wavelength, and wave propagation speed. In the examination and analysis that have been carried out, it has been found that increasing wave height and amplitude correlates with increasing the inclination of wedges. The frequency and speed of the waves are linearly related to changes in the rotation speed of the wave generator. For the characteristic wavelength, there is inverse relation to the rotational speed. Based on this study, the wave simulator system and video tracking analysis application can be used to increase the understanding of wave parameters. In addition, this research can also be used as preliminary research on developing a prototype for an ocean wave energy converter on the laboratory scale.

“…This course weighs 1 credit and is taken in semester 1. The practicum "Linear Momentum Collisions" in the Basic Physics Practicum I course aims to test the applicability of the law of preserving linear momentum in collisions [18], [19]. The law of conservation of momentum states, in a perfectly elastic collision between two objects in a system, the total momentum before the collision is equal to the total momentum after the collision [20], [21].…”

“…In physics learning, it should not only focus on concepts and facts, but should be integrated with experience in students so that students can understand scientifically (Rahmadita et al, 2021;Wardani & Jatmiko, 2021). The process of physics learning activities provides space for students to develop 4C's (critical, creative, collaboration dan communication skills) (Aliftika & Purwantoutari, 2019;Khoiri et al, 2021;Khoiriyah & Suprapto, 2021;Khotijah et al, 2019).…”

Critical thinking skills of students in Indonesia are still very low, then one way to improve CTS is to collaborate learning with real-world problems that can be found in everyday life with the help of existing technology as a learning tool. The purpose of this research was to find out the profile of students' critical thinking skills and the implementation of problem based learning implementation with assisted augmented reality books in high schools, especially on learning physics with parabolic motion materials. The method research is included in preliminary research with a sample of 190 high school students in Surabaya, East Java. Data collection techniques by sharing critical thinking skills tests, student response surveys and interviews of students and teachers. Then the data is analyzed using qualitative descriptive to represent the results of the reserach. The findings of the study are 1) Students' critical thinking skills are still in the low category. 171 students with low categories, 19 medium categories and none at all high-category students; 2) The lowest indicator of critical thinking skills is interpretation; 3) Teachers still use conventional lecture methods and teaching materials during learning; 4) The implementation of problem-based learning models with integrated AR books is expected to improve students' critical thinking skills on physics materials. It can be concluded that to improve students' critical thinking skills, it is important to innovate learning, especially in physics learning, one of which is the implementation of Problem Based Learning assisted by Augmented Reality books.
