Abstract

This study aims to design and develop learning media based on augmented reality on hydrocarbon material and its validity to determine the media's feasibility and increase students' multi-representation ability. This research is a type of development research using Design Research and Development (R&D). The product validity test phase was carried out by two material experts and three media experts. In addition, testing was carried out on the responses of the participating students. The implementation stage of learning was carried out by class X TKJ 2 SMK Gondang Pekalongan with a total of 32 students. The data analysis technique used a questionnaire instrument and the technical descriptive statistical analysis. The results of this study are: (1) the development of augmented reality-based learning media on hydrocarbon material in the form of an android application consisting of five main menus, namely basic competencies and indicators, materials, AR camera, practice questions, and the identity of the researcher, as well as seven molecular cards of the structure chemical compound molecules; (2) validity assessment by material experts with an average score of 85% in the "very valid" category and the validity assessment by media experts with an average score of 94% in the "very valid" category; (3) the feasibility test results for using media in the implementation of learning obtained an average student response score of 78%, with the "feasible" category used as learning media. The increase in multi-representation abilities is shown by increasing student learning outcomes using multi-representation questions, including macroscopic, submicroscopic, and symbolic levels. The macroscopic level increased by 27.50%, the submicroscopic increased by 36.70%, and the symbolic level increased by 33.30%. The results of this study indicate that augmented reality-based learning media on hydrocarbons is very suitable for use in chemistry learning and has been proven to increase students' multi-representation abilities

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

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

Abstract

This research developed a paper indicator made from extracted Ashoka flower, Ixora coccinea Linn, with solvent and the soaking period variances. Ashoka flower is a plant containing anthocyanin pigment. The plant is sensitive to acidic levels of pH. The content of the Ashoka flower brings significant potential as a natural indicator. The researchers extracted the anthocyanin pigment of the lower with the maceration method with 96% and 70% ethanol solvents for 24 hours. The researchers calibrated the extracted ethanol with buffer solution under pH 1-12. Then, the researchers cut 42 Whatman papers sized ±5x1 cm. The researchers put the papers into the mixtures of the extracted ethanol within 48 - 72 hours of the soaking period. After that, the researchers dried out the papers and examined the solution in terms of acid-base level. The papers made of extracted ethanol from Ashoka flower on solutions of HCl, CH3COOH, NH4OH, NaOH had their colors changed into brighter pink, pink, light green, and green-brownish. The color changes on the developed paper indicators made of extracted ethanol from Ashoka were extremely clear with a condition of 96% ethanol solution and 72 hours of soaking period.

Abstract

Experimental activities are part of physics learning process with the aim of gaining knowledge and having good understanding of physics concepts. Sound and organ pipes are the main subjects discussed in physics and engineering lessons. These materials contain facts accompanied by actualization in everyday life in social life. However, the fact in high school (SMA) physics learning is that experimental activities in supporting students’ learning and understanding have not been widely carried out. This is due to the lack of practical support tools. The purposes of this research are to design a sound experimentation tool design of an open and closed organ pipes and to determine the value of the speed of sound which propagates through air medium using a data acquisition technique assisted by sound analysis oscilloscope software. This type of research is a Research and Development research with five stages referring to the ADDIE model. The first stage was analysis, that was done by conducting a study of the problems of physics learning at senior high school level, especially in sound chapter. The second stage was design, namely designing experimentation tools. The third stage was development, that was done by providing materials that were used in the experiment. The fourth stage was implementation, that was testing the tool which had been made combined with sound analysis oscilloscope software, and the fifth was conducting an evaluation and feasibility test based on the validity of the experimental data. The data analysis technique used average and linear regression by utilizing the results of data from frequency analysis using sound analysis oscilloscope software. The results showed that the experimentation tool in this study was able to be used as learning media for the sound and open and closed organ pipes materials. The experimental results obtained that the speed of the sound waves propagation in air for an open organ pipe was v = 332.19 m/s with an accuracy rate of 97.70%. While the value of the speed of the sound waves in air for a closed organ pipe was v = 334.69 m/s with an accuracy rate of 98.44%.
