Published: July 2022

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.

Published: July 2022

Understanding the concept and having a positive attitude towards studying physics is a requirement to succeed in studying physics. Studies have shown that students have low conceptual understanding and do not yet have positive attitudes toward learning physics. This research aims to analyze students' conceptual understanding of Straight Motion for class X, analyze students' attitudes towards learning physics, and analyze the correlation between conceptual understanding and students' attitudes towards teaching physics. This type of research is descriptive research with a quantitative approach and the population of all students of class X SMAN in Payakumbuh City and a sample of 205 students. The sampling technique used the purposive sampling technique using the Four-Tier Multiple Choice and Likert Scale. The research results revealed: Students understood the concept of 33.93% in the medium category. Students' attitudes towards studying physics are good, but the indicators of interest in increasing the time to study physics tend to be in the reasonably good category. The correlation between conceptual understanding and student attitudes with a significance value of 0.000 and a correlation value of 0.490 means that the correlation between the concept understanding variable and the student attitude variable is moderate.

Published: July 2022

Pre-service elementary teachers’ attitude in supporting the achievement of the ecosystem and environmental balance is necessary to implement. Most global warming topic taught in natural science learning has yet to be based on environmental orientation. This research purpose was to analyze pre-service elementary teachers’ attitudes in preventing global warming and environmental health issue. The research uses a descriptive method with the data collection technique of the survey. The research samples include 239 students of the Department of Elementary Teacher Education in Jakarta, Bogor, Depok, Tangerang, Bekasi (Jabodetabek) area. These students are pre-service elementary teachers. Data analysis used is by comparing the average score of each item and indicator. The research result indicates that the average score for attitudes is 87.33 suggesting that the attitude score is relatively high. The attitudes, however, have not been fully implemented in the form of attitudes to prevent global warming and environmental health issue. Natural science learning plays a prominent role in providing understanding related to global warming. The research results also recommend the application of more applicable lecture activities to the pre-service elementary teachers to improve the pre-service teacher attitude in natural science learning. The research concludes that the score of the pre-service elementary teachers’ attitudes is within a high category

Published: July 2022

This study aims to analyze the application of character education in learning biology in Genetic Engineering material at State Senior High School 7 Bengkulu and see what efforts are being made by teachers and schools to instill such character education. This research is qualitative description research with 29 research subjects as grade XII students. The instrument used was in the form of a questionnaire and several interview questions. The results showed that the picture of biology learning character education in Genetic Engineering material in State Senior High School 7 Bengkulu had begun to be embedded but still needed guidance to be more focused on understanding the concepts, impacts, and application of genetic engineering techniques because teachers had not fully applied the teaching methods of character education in class. The picture can be seen in the observation data, questionnaires, and interviews of honest, disciplined, democratic, communicative, and creative values that have begun to develop. Caring, responsibility, and sociality are well entrenched. Independence is still very much needed to be considered while religious have begun to appear. In an effort to create character education attitudes that will be the basis for dealing with scientific and technological progress, the school has also implemented a number of support programs to improve or train character education attitudes

Research has been carried out on the preparation of active natural zeolite impregnated with nickel followed by activity testing through the hydrocracking catalytic reaction of n-Hexadecane. Active natural zeolite was obtained from PT Prima Zeolita Yogyakarta. The nickel concentration in the zeolite sample was carried out by ion exchange method with [Ni(NH3)6]2+ precursor solution with a concentration of 0.06M. The nickel content of the catalyst was determined by Atomic Absorption Spectrophotometer (AAS). The hydrocracking reaction used a fixed bed reactor system. Ratio of feed (n-Hexadecane) : catalyst = 3 : 1 (in gram). Catalysis study also carried out at various temperatures, from 315oC - 450oC at certain nickel content. The results of the catalytic reaction at each temperature after passing through the cooling system there was a liquid fraction that had been successfully accommodated then weighed and determined the percent of conversion. Furthermore, for the determination of Ea and the order of the reaction using linear regression calculations. The results showed that the catalytic reaction using an active natural Ni-Zeolite catalyst in the n-Hexadecane hydrocracking process resulted in different conversion results depending on the temperature of the catalytic reaction. The largest conversion was obtained at a temperature of 450oC, which was 35.18%. The reaction order was the first-order reaction (n=1). Meanwhile, the activation energy or activation energy (Ea) of the catalytic reaction in the n-Hexadecane hydrocracking process using a natural Ni-Natural zeolite catalyst with a nickel content of 2.0% (w/w) was 127.071 kJmol-1.
