Abstract

Many students have not yet completed the science learning process, so there is no need for students to take part in the improvement program to meet the Minimum completion criteria. The purpose of this study was to analyze the science learning outcomes of VIII-grade students of Air Setan Middle School through the Problem Based Learning model. The design of this study used a design that was created pretest-posttest Group Design. Samples are taken at random (simple random sampling). Data collection techniques using essay questions, this test is done twice, namely before (pre-test) and followed (post-test) learning process. Data analysis techniques using the t-test, in using this t-test, both the experimental class and the control class data must be normal and have a homogeneous variant that is tested for normality and homogeneity before testing the hypothesis with the t-test. Learning outcomes using problem-based learning are better because this learning involves students solving problems, by means of their creative ideas and ideas, so students do not easily forget the lessons they have learned

Abstract

This research was conducted by making a rectangular slit using a razor blade as a narrow gap in the Fraunhofer diffraction experiment. The intensity distribution measurement on the resulting diffraction pattern uses a voltage divider circuit. This circuit takes advantage of the nature of the LDR, which changes resistance when exposed to light. Experiments show that a diffraction pattern screen when a 560 nm coherent light passes through a narrow rectangular slit made of razor cut. We measured the narrow gap using a tracker application with the resulting gap size (0.3564 x 0.4677) mm. The ratio of the intensity distribution of the x-axis bright pattern on the Fraunhofer diffraction by a rectangular slit with slit size height x width = (0.4677 x 0.3564) mm from b = -5p to 5p (maximum 4, maximum 3, maximum 2, maximum 1, central maximum, maximum 1, maximum 2, maximum 3, maximum 4) is 0.000873; 0.000763; 0.005395; 0.020583; 1; 0.039658; 0.008088; 0.002554; 0.001218. The ratio of the intensity distribution of the y-axis bright pattern on the Fraunhofer diffraction by a rectangular slit with slit size height x width = (0.4677 x 0.3564) mm from g = -5p  to 5p (maximum 4, maximum 3, maximum 2, maximum 1, central maximum, maximum 1, maximum 2, maximum 3, maximum 4) is 0.001890; 0.001469; 0.002447; 0.040516; 1; 0.037141; 0.006482; 0.001690; 0.000440. This study indicates that diffraction experiments and the measurement of the diffraction pattern’s intensity can be carried out with simple materials and equipment and can be used in the correct experiment.

Abstract

The purpose of this study was to identify the implementation of the experimental method in science learning and the obstacles faced by teachers, as well as to identify the application of pre-lab in science learning. Research design was survey which is non-experimental quantitative research. The participants were 26 teachers who teach subjects in the sciences, namely Chemistry, Biology, Physics, and Science as integrated subjects. Data were collected through online questionnaires using google forms and were analyzed descriptively. The results show that experimental activities have not been fully applied to science learning. Most teachers provide the tools and materials needed in learning activities in the laboratory and provide work procedures to students. The constraints that are faced by teachers in applying the experimental method are related to facilities and infrastructure, student characters, and experiment time allocation. Most of the teachers have also carried out pre-lab activities, but they are still dominated by lectures from the teacher. This study also explored the pre-lab model to be developed, almost all teachers agreed if the pre-lab was developed in the form of virtual learning. The forms of media that teacher’s interest in for pre-lab activities are videos and android applications

Abstract

Research has been carried out with a device to observe the phenomenon of Rayleigh Benard convection, made of a glass box bounded by a lower plate and an upper plate. The bottom plate is hotter than the top plate which functions to heat the horizontal fluid layer from below. This study aims to observe the phenomenon of water molecule movement. The observation medium was water mixed with teak sawdust as a representation of water particles with an average density of mean=0.99 g/cm3. The variation of water thickness (d) used 5 cm and 6 cm with variations in temperature difference (DT) with an average increase of 50°C. Data was collected with a cellphone camera and run with Windows Movie Maker software which has a time accuracy of up to 0.001 seconds. It was observed that an increase in the temperature difference (DT) between the two plates resulted in an increase in the velocity of motion of water particles in convection which is depicted by a v-DT diagram. Due to the difference in temperature (DT) also results in the movement patterns of water molecules, namely laminar and turbulent. The turbulent phase with the Rayleigh number value R~107, indicated that the flow of water particles is getting faster, the direction of the flow of the particles starts to become irregular and sometimes signs of a water vortex appear. At different fluid immersion results in the start of a turbulent phase. The turbulent phase for d=5cm is observed at DT~30°C, and d=6cm at DT~20°C. Furthermore, this RBC phenomenon is used as a representation of learning natural phenomena in air fluids, namely whirlwinds as an event due to differences in temperature and pressure of a fluid
