Abstract

Creative and analyzing thingking is a competence that students need in studying physics on the subject of mechanical waves by developing ideas with the result that they can be analyzed through examples of everyday life. The competence of creative thinking and analyzing of class XI students in SMA Negeri 1 Dempet, Demak Regency when studying physics is less optimal and feels bored faster. This is because students still depend on the formulas used without knowing the concept, and they are passive in participating in learning activities by only paying attention to the teacher's explanation. Learning that is suitable for developing creative thinking and analytical skills is to use the Problem Posing learning model in terms of skimming and mind mapping, with the aim of research to determine the effectiveness and describe the competence to think creatively and analyze. This study used a mixed methods and the sample was selected through purposive sampling technique so that the experimental class and control class were obtained. In the experimental class, the treatment was given to the Problem Posing learning model in terms of skimming and mind mapping, while the control class was given treatment of the Problem Based Learning learning model. The results showed that the more students follow the learning using Problem Posing through skimming and mind mapping techniques, the better the final competence test results for creative thinking and analyzing. This is shown based on triangulation in each category of skimming and mind mapping observations with the final ability of creative thinking and analysis

Abstract

The dynamics of the spring-pendulum system with two degrees of freedom were studied. The motion of this system is restricted to be in a vertical plane so that the chosen generalized coordinates are the increased length of the spring  and the swing angle of pendulum . Hamiltonian of the system is obtained from the Legendre transformation of Lagrangian. Hamilton’s equation yields four differential equations that represent the dynamic of the system. The obtained results were visualized in configuration space and phase space trajectories. It is shown that generally the greater the initial swing angle, the more complex pattern will occur followed by the appearance of chaotic phenomena.

Abstract

The purpose of this research  was to examine the value of the Wien’s constant using PhET Simulation virtual laboratory and simple numerical approach. The independent and dependent variable is blackbody temperature (T) and maximum wavelength (λ_max). In the use of a virtual laboratory, research is carried out by shifting the black body temperature feature so  the graph will display a spectral power density that varies to the wavelenght. Numerical approach was used in this research is Newton Raphson methods by Python program. Both of simulation and numerical approach yield the value of the maximum wavelength (λ_max) for a black body temperature variation. The black body temperatures and their appropriate maximum wavelength data then analyzed using linear regression. Final result show that value Wien’s constant using PhET is 2,93 × 10-3 mK with relative error obtained is 1,07 % while using Newton Raphson the Wien’s constant value obtained is 3,07 × 10-3 mK with relative error is 5,90 %. The two approachs carried out produce data that slightly different, but still in a very good accucracy range when compared with theory. So, PhET Simulation and Newton Raphson methods effective to examine the value of the Wien’s constant.
