Abstract

Abstrak. Development of Problem-solving skills is needed in physics to master concepts. This goal can be achieved through the implementation of the right steps. The purpose of this research is to describe models, strategies, media, and instruments that can be used to develop problem-solving skills. Learning models that can be applied include PBL, PIL, Inquiry, IBMR, PO2E2W, Discovery Learning, PjBL, Virtual Laboratory, CPSL, and CTL learning models. Learning strategies can be in the form of peer instruction, scaffolding, Polya strategies, Heller, Keith, and Enderson strategies, knowledge planning strategies, Rosengrant strategies, and visualization of the imaginary world. Various supporting media can be in the form of computing media, the development of teaching materials, mobile applications, and games. The instruments used for assessment and questionnaires.

Abstract

Practical instructions for practical activities in computational physics courses have been successfully developed with material on the Laplace equation for temperature distribution. This research aims to produce practical instructions and determine the characteristics, feasibility, and responses of students to practical instructions for computational physics on the Laplace equation. The research design used is development research or R&D (Research and Development) which was modified from Sugiyono. The research was carried out at the Computer Laboratory of PGRI University Semarang with Physics Education study program students as research subjects. The research results show that the computational physics practicum instructions developed have the criteria "Very Feasible" based on validation from three computational physics experts with respective percentages of 96%, 99% and 93%. The characteristics of this computational physics practical guide are that it is prepared using computational thinking techniques and written using structured documents (LaTex), presented explicitly and equipped with algorithms, solving with two different scenarios (iterations and matrices) in one case as well as writing coding. uses the latest software (Python) and is equipped with algorithms. This computational physics practical instruction received a very good response from students with a percentage of 87% in the initial trial and 88% in the usage trial.

Abstract

Abstract The purpose of this study is to determine the terminal velocity and fluid viscosity using falling ball viscometer with video tracker application. The terminal velocity is obtained by videoing the ball falling into a tube 115 cm long and 5 cm in diameter which has been filled with fluid and then the video is analyzed using tracker application. The fluids used are oil SAE 20W-50 and glycerin. The balls used are namely as balls I, II, and III with diameters of 1,09cm, 1,56cm, and 1,57cm. Once the terminal velocity of the sphere is known, the fluid viscosity is obtained by using Stokes law principle. The terminal velocities of balls I, II, and III in oil SAE 20W-50 are 0.247m/s, 0.250m/s, and 0.187m/s, while the terminal velocities of balls in glycerin are 0.092m/s, 0.090m/s, and 0.065m/s. The average fluid viscosity of oil SAE 20W-50 and glycerin are 0,834Ns/m2 and 1,807Ns/m2.
