Abstract

The aim of this study was to determine the effect of the intensity of the yellow LED light and the sound intensity of religious music (Asmaul Husna) on the growth of various types of chili plants in indoor system. The research method uses experimental research. This research was conducted in Baitussalam District, Aceh Province. This research was conducted for a month. Based on the results and discussion, it can be concluded that exposure to LED lights and religious music (Asmaul Husna) has a fairly good effect on the growth of stem height, number of leaves and leaf width of the three types of chili plants tested. This is because the addition of light in the form of LEDs and sound can help the plant photosynthesis process to be more productive and accelerate the growth of the third type of chili. From the three types of chili, the most significant effect is in terms of plant height, leaf width and number of leaves found in chili peppers compared to the results obtained on cayenne pepper and green chili.

Abstract

The ability of students in solving physics problems used Polya's theory is still at a low level, in general students have difficulty in solving physics problems at the stages of planning and implementing problem solving. This study aims to determine the level of difficulty of students in solving physics problems used Polya's theory and find out what are the difficulties of students in solving physics problems used Polya's theory. The research approach used is mixed method, with the explanatory sequential design. Data collection techniques used tests and interviews. The results of data analysis show that the very high level of difficulty of students in solving equilibrium problems of rigid bodies is at the stage of seeing / checking back, but the difficulties experienced by students at this stage are very dependent on the other three stages of Polya, namely understanding the problem, planning problem solving and implementing problem solving. Students' difficulties in solving physics problems used Polya's theory, among others, students had difficulty in translating or changing the problem in physics symbols, students had difficulty in making plans because they did not know the formula that should be used, students had difficulty in completing mathematical operations and students did not re-examine the solution steps and answers that had been obtained so that some answers were still not correct.

Abstract

This study aims to identify students' misconceptions on the material of Kinetic Gas Theory in physics learning. This study uses a qualitative approach and the type of research used is descriptive research. The subjects of this research were 20 students of class XI. The data was collected by means of a diagnostic test technique equipped with CRI (Certainty of Response Index) and free-guided interviews. The results of data analysis show that the average Lucky Guess level is 13%, concept understanding is 39%, not understanding concept is 20%, and average percentage of misconceptions are 28%. Based on the identification results, the highest misconceptions in students appear in the indicator of the question of calculating the ideal gas equation by 55%. The results of the analysis and interviews that have been carried out, misconceptions occur due to the students themselves because they do not understand the concept as a whole and the lack of interest of students to repeat the lesson.
